An Act of Desperation

To the casual observer, it can certainly seem odd that two nations, which between them had launched a grand total of one satellite, would agree to do something as ambitious as landing astronauts on the Moon. With the benefit of hindsight, the treaty signed by Harold Macmillan and Charles de Gaulle in July 1963 could only have been signed in the early-middle years of the 1960s. Any earlier, and the technology needed to achieve its goals would have looked far beyond the reach of any nation. Much later, and the national and political imperatives to commit to such a strange and wonderful idea would have faded.

1963 has since proven to be a vintage year for conspiracy theories. The “Selene Bubble” is one of them; alleging that there was a co-ordinated set of contrived co-incidences in the nature and timing of events in the months leading up to the formation of the Project. According to those who believe in such things, it was all too good to be true. While they might make for entertaining films, most conspiracy theories (and certainly that one) are just that: Theories.

In practice, sometimes, coincidences happen and actions that seem odd today looked like good ideas at the time.

The Project was formed out of both hope and desperation, and even if it were to be cancelled later on (and there were many who thought it would be), in the summer of 1963 it suited almost everyone’s needs.

Britain’s fledgling civil space programme received an immense boost, not just in funding but in prestige; it was no longer just a joke, a “bunch of boffins launching tin cans into outer space…” The satellite TV relay programme had the support of the GPO, the Foreign Office and the MoD, but its most powerful ally was the BBC and through them, much of the TV-viewing public. Although Selene would not directly contribute to the relay satellites themselves, it would help expand the industry that would build them and guarantee the future of the rockets needed to launch them.

Many in the military and the firms involved with Britain’s Black Anvil missile programme supported Selene. Having an additional use for “their” rockets could help guarantee the future of the missile, by making it very difficult to cancel without disrupting both civil and military programmes. Selene would also help make the deterrent more reliable; The Project would launch dozens of probes and test flights, every one of which would be a chance to gather flight data and improve on the design of Blue Streak or Black Anvil.

It suited the British government. Aside from serving as a short-term distraction from an economic slowdown and political scandal, it made strategic sense. Without a major new defence or civil aviation programme, the future of Britain’s surviving aerospace firms looked very uncertain.
At the time, all that was left for Hawker-Siddeley was the P.1127 VTOL development programme and Blue Streak production (which was scheduled to end within a couple of years). Having failed to agree a deal to build an SST and with the prospect of a high-speed bomber contract for the RAF looking increasingly remote, BAC’s entire future depended on the development of Black Anvil and the small “1-11” jet airliner.

It was believed that the cost of supporting these firms (in other words: nationalising them) would be much the same as the contracts needed to keep them in business doing something useful. Having a world-class, privately owned aerospace industry for the same price as a moribund state-owned one was an easy decision for a Conservative government. Of course, it was popular with the owners too.

In France, the reasons were more nationalistic but equally pragmatic. The nation was seeking to move on from the memories of defeat in war, retreat in Indo-China and Algeria and the collapse of the French government. General de Gaulle was President of a “new France”, a proud nation with a booming economy, determined to take a leading role in world affairs.

The development of the French aerospace industry was one of the government’s top priorities. Research into nuclear weapons had produced a workable A-bomb based deterrent and a long range missile programme had been underway for some time. However, it was accepted that this would benefit greatly from the years of practical experience already acquired by British engineers. Earlier attempts to achieve outright Anglo-French cooperation in missile development had failed due to British indifference, French suspicion and the nature of Anglo-American agreements. Now, both countries would work together in the civil space sector; and a lot of technology and experience would naturally be passed on to French engineers.

From the strategic perspective, both nations had an eye on the future of warfare and the balance of power. Both the USA and USSR were actively engaged in lunar programmes. The “unspoken purpose” of the Selene Project was to ensure that Britain and France were not entirely left behind in the race to reach (and by implication, perhaps, control) the Moon. If future deterrents were to be placed in space, or if the Moon were to become a proxy battleground for the great powers of Earth, then all non-spacefaring nations could easily become irrelevant.

However, Selene was not going to be an all-out military research programme. It would be a steady, resource-limited technology development project, starting with “simple” Earth-orbit satellites and eventually reaching the Moon. Nominally, this would be achieved within 10 years, by which time it might be necessary to extend the Project towards other goals. It certainly wasn’t going to be a race with anyone; both nations assumed that both the USA and USSR would reach the Moon before them, possibly even by 1970. The Soviets led the world when it came to rocket launch capacity, while America seemed willing and able to pour vast amounts of money into their lunar plans. NASA’s budget would be the equivalent of £900M in 1963/4 (of which about £500M would be spent on the lunar program).
By contrast, joint funds allocated directly to Selene over the first year would be £42M, although this was expected to rise to well over £100M in subsequent years. Although such sums were large by Anglo-French standards, this relatively tiny budget seemed realistic, as Selene would rely on developments elsewhere in the industry (such as the availability of the Black Anvil rocket).

Within a fortnight, "The Selene Project", a hurriedly produced book containing details of what will be accomplished and when, goes on sale in both French and English. Despite being a short, semi-technical and legal document, it sells well as it offers the public their first insights into the Project, including a list of plans, dates and major milestones to be achieved:

1963-4 - Develop initial designs for the various missions and types of spacecraft, to be finalised by 1965.
1965 – First of a set of joint Earth orbit satellites, to be built in France and launched on Blue Star.
1966 - First of a series of unmanned lunar orbit satellites which will photograph the surface, to be called "Lunar Orbiter" (British built).
1967 - First of a series of unmanned lunar landers, to be called "Explorateur" (French built).
1968 - First manned flight in Earth orbit. Earth orbit test flights will be named "Aurora".
1969 - First flight of the lunar capable launch vehicle and unmanned "Lunar Orbiter B" missions to take high resolution surface images.
1970 - Long duration manned flights in Earth orbit.
1971 - First manned flight to lunar orbit, lunar missions to be named "Selene".
1972 - Manned lunar landing.

With the grand announcements and over and the ink dry on the treaty, it is time for the scientists and engineers to take over.
The first question they must answer is:

“How on Earth do we go to the Moon?”
 
Hello All,

This story is a follow on from my previous thread Quaerere Caelis - Prelude to Selene which will probably answer some of the "Ehhh...What?" questions you may have about the way this story starts.

No project would be complete without a patch:

Selene Logo2.jpg

Selene Logo2.jpg
 
And those theories on the Selene Project, IMO, will be as popular ITTL as the JFK assassination theories are (IOTL and ITTL)...
 
Cool!

One allohistorical in-joke... any chances for having a Blue Streak launch site in Wales? (Gwynedd, specifically.) One is of course to make a fictional Blue Streak launch look more real. The other would be that the fictional village the missile was launched from looked similar to a real village of sorts (Portmeiron)- whose founder, Sir Clough Williams-Ellis, was big friends with Bertrand Russell, both of whom hosted CND-type conferences there.
 
Query:
the requirement for your rockets was that they be able to stay fuelled for 7 days minimum.

Obviously, not a whole lot of problem for kerosene, but the liquid oxygen would be a challenge.

Do you have inlet and outlet pipes so LOX is continually pumped out of the rocket, chilled rather further, and pumped back in in a continuous cycle?

Sure, adding a (probably portable and temporary) extra blanket of insulation will help, but OTL, there's a lot of boil off of oxygen on rockets that use LOX.

Given this rocket is meant as a missile in silos, if all you did was replenish the LOX, the boiled off O2 would mean that the oxygen content in the silo quickly rises to dangerous levels, no?

Just wondering how they're tackling the challenge.

You've also got 7 days worth of ice accumulating.

I don't doubt technical solutions are possible. I also don't doubt that they'll be far trickier than the proposers believe...
 
The title make me curious
after first post you got my full attention

let see on Hardware
Britain got Blue Streak a MRBM based on Atlas ICBM, last one made good job and became a Launch rocket, despite addiction to explode (the Atlas not Blue Strak)
Black Anvil is ITTL project i guess a Short Range blister missile, that serve also as upper stages for Blue Streak aka Black Prince ?

french got "precious Stones" a family of Sounding rocket for Science and Military purpose
all solid rocket for moment, they work bigger liquid fuel rocket "Émeraude" (that become in 1965 Diamant A what launch french first satellite Asterix)

now with a Blue Streak with a Émeraude down side to half you get Launcher in size of Atlas Agena for Selene 1965 secluded
but for need bigger rocket for Rest especially for Lunar mission
something in size of Saturn IB or Saturn V

I'm sure the conspiracy theories will multiply and expand (they'll try to suppress them - and that'll be a conspiracy too).

Orville_third
Blue Streak in Wales? - No, although Llanbedr airfield will make an appearance in other ways.
Practical objection - any launch site will be a target for the Soviets. Fallout would be carried East across the centre of the UK. Blue Steak launchers are planned to be in the East (as they were in reality).
Personal objection - I have a house overlooking that estuary, I don't want noisy rocket launches and commie nuclear attacks interrupting my day. :)
Although the idea of a secret missile base under a mock Italian village ... that would certainly add to the plot of The Prisoner.

Dathi THorfinnsson
LOX/LCH4 boiloff - certainly a problem (amongst others). There's a roundup of Black Anvil due in a few posts, so you'll have to wait until then to find out how big a problem.

Michel Van
Yes, much bigger rockets are planned. Lots more detail and illustrations to come. Black Anvil will be an ICBM.

There's a bit more story development to come, then i'll try to post a glossary of what the various programmes/rockets are.
 
AVEZ-VOUS CUPPA?*

One of the first challenges for Selene engineers is to devise a method by which a lunar landing can be made, as this will influence the design of almost every ship, stage and system that will be needed. British and French teams formally meet for the first time on the 8th July. Although all of them are highly skilled designers, diplomatic talent is not always in evidence.

Both sides have studied the issues extensively, but from quite different viewpoints.
The British approach has been engineering focussed and benefits from a good knowledge of the operational issues involved in “real world” missile and spacecraft design, rather than just theories on paper. However, a good many of their concepts suffer from being limited to variations of known designs, typified by several studies showing what could be done with a Black Anvil rocket plus a new upper stage.

Uninhibited by the need to stick to any existing designs or systems, French engineers have explored a much wider range of concepts on a theoretical basis.

However, the failure of BAC and Sud Aviation to agree a design for a supersonic airliner in 1962 has left a legacy of cynicism and distrust. Many of the same people who failed to agree then are now involved in these discussions. The British side tends to dismiss concepts very quickly when their practical experience tells them that the ideas are too optimistic. The French engineers have a lot of ideas. Personal and national pride start to enter the discussions.

What happens when the irresistible force of French engineering élan meets the immovable object of British engineering pragmatism? – Bruised egos.

It is not a good start, but after the first few meetings the teams start to become familiar with each other’s capabilities and working styles and there are hints that progress can be made. Over the next few weeks, the natural camaraderie often found between engineers smooths over many of the national difficulties and progress becomes much easier. Both sides begin to develop a better understanding of the magnitude of the task they are attempting and the early heated discussions move towards a freer exchange of ideas and information.

Two groups of solutions emerge as the most practical.
- "Direct" missions, where a lunar ship is launched on a powerful rocket, or is assembled in Earth orbit. This one large ship then departs for the Moon, lands and returns.
- "Depot" missions, in which smaller vehicles are pre-placed in different locations such as in Earth orbit, lunar orbit and on the surface. A crewed ship then flies between the depots, refuelling and resupplying as needed.

British ideas tend to be variations on the "direct" mode, the best known of which is a BAC study which calls for booster stages to be launched separately then linked together in Earth orbit. It is also known to be the mode favoured by NASA for the American lunar programme.

French studies tend to be more complex, usually involving the “depot” concept with several different types of vehicles. However, these innovative ideas often result in lower mass to orbit requirements, as each vehicle can be optimised for its primary task; for example if there is a dedicated Orbital Transfer ship, a separate Lunar Lander doesn’t need to carry a heavy heatshield all the way to the Moon and back to Earth.

British engineers reject the pure "direct" mode, in which the whole mission launches on a single rocket. This would require either a huge new launcher, or a costly and complicated nuclear upper stage. Contacts with the US have provided some details of the American ROVER and NERVA nuclear engine programmes, which are only showing slow progress despite very significant investment. Both nations also agree that a pure "depot" mode, with bases or stations in several locations, is likely to be far too expensive.

Several other costly or complex mission modes are rejected as the summer draws to a close. A concept involving a lunar orbit space station “depot”, which could act as a base for expeditions to the surface, lacks flexibility and would still be excessively expensive.
A related concept uses a separate "mother ship", "lander" and “ascent ship”. Although this is superficially attractive in terms of mass efficiency, is considered to be too difficult to build due to the need to build three different spacecraft, all of which would need to be capable of operating independently. In an attempt to gain some early credibility for the Selene Project, the idea is passed on to NASA, as it would seem to fit well with the design of their Apollo CSM. Polite thanks are received back, however it seems they have previously rejected the idea.

Studies focus down onto two options, the last survivors of the “direct” and “depot” concepts: Earth Orbit Modular (EOM) or Lunar Surface Refuelling (LSR).

An EOM mission would involve the launch of separate, self-contained booster stages into low Earth orbit. These would be docked together and used in sequence to send a crewed vehicle into lunar orbit, then start the landing. The separate crew vehicle would complete the landing and then return to Earth under its own power.

An LSR mission would involve one or more unmanned "tanker" spacecraft, which would be sent directly to land on the Moon. A crewed vehicle would follow and land nearby, refuelling itself from the tanker for the trip home.

These options need much more detailed study, so BAC and Sud Aviation are awarded short term study contracts to analyse the merits of the EOM and LSR mission modes. Both firms are instructed to work with their respective national ministries to ensure reasonable costing methods are used.

The Go Ahead

Jul-63
After months of speculation, the GPO announces that it will go ahead with a programme to develop TV relay satellites, as an alternative to upgrading the existing transmitter network. An experimental spacecraft to broadcast low power signals is already planned for launch next year. The full size satellites will be built by Hawker Siddeley, with the transmitter payload developed in house at the GPO. The first launch of a prototype is planned for 1967. Once fully operational, satellite signals will carry a 625 line picture in colour. By 1969, two satellites will be able to support up to 4 simultaneous TV channels.
Next year, a second BBC channel will be launched on the existing 405 line network in most urban areas. The old network will be phased out in the mid 1970s once the satellite system is fully operational and the public have had time to convert to the new TV sets that will be needed.


Aug-63
Outline work sharing agreements are concluded and some of the first Selene contracts are awarded.
The UK will build and launch the "Lunar Orbiter" probes on an improved version of the Blue Star rocket. Saunders Roe are contracted to produce an SUS based spacecraft to carry a camera and film readout payload to lunar orbit. 6 spacecraft are planned.
France will develop and build the "Explorateur" unmanned landers to prove the techniques needed to land softly on the lunar surface and return scientific data. Sud Aviation is awarded a contract to build ten landers (two test versions and eight flight articles).
The UK will develop an upper stage for the Black Anvil missile, which will propel these landers towards the Moon. BAC, who are building Black Anvil, are contracted to produce the stage.

Aug-63 Overseas
Responsibility for the X-20 DynaSoar project is transferred entirely to NASA. Earlier in the year, the programme had been deemed unsuitable for USAF needs, however the aerodynamics and materials used on the vehicle are regarded as worthy of further study by NASA for use on future reusable spacecraft. NASA re-christens the programme the "XS-20 Spaceplane" and plans to conduct a series of six research flights in 1965-66.

Aug-63
The first Blue Streak hardened shelter is completed in East Anglia. Tests and checks will take several months before the "silo" (as they are publically described) is declared operational. An additional 38 shelters are scheduled to be completed across the UK over the next 16 months.

There is considerable debate among pilots and engineers over the size of the crew needed for Selene flights. Two is regarded as being too small. Three is felt to be the idea number, but would have the problem of it not being possible to split equally between British and French astronauts. Four crew would need a large spacecraft, at a significant mass penalty.

Bristol Siddeley test fire an improved thrust chamber for their J-650 engine. Constructed of higher grade steel tubing and brazed under better controlled conditions, this chamber proves much more resilient than previous versions. Thermal damage on the injector is eliminated; the firm has used a porous steel mesh, originally developed for the nuclear industry, in place of the solid plate used on previous engines. 17 firings, totalling 366 seconds of burn time are completed successfully.

F-15
Military test flight (publicly referred to as simply "Blue Streak").
It is the first test of a three-stage Blue Star rocket, equipped with the Satellite Upper Stage (SUS). This multi-purpose stage is intended to act as both a booster during launch and as a manoeuvrable platform for various civil and military payloads when in orbit.
The mission was supposed to be a day-long flight to test the systems of the SUS, but an electrical failure in the second stage guidance system left it pitching down at too high a rate. The third stage (the SUS) separated and fired as planned, but with a nose down attitude it accelerated back towards the atmosphere. Orbital speed was achieved, but the payload was descending too quickly and it burned up 5,400km downrange. Mission failed, however the firing of the SUS stage was successfully demonstrated.

Saunders Roe are ordered to investigate the reliability of their upper stage (the second stage of Blue Star). Of the four firings to date, three have suffered from control problems.
More of the complex (and expensive) SUS equipped flights are now planned. If there are faults in the second stage, these missions may have to be delayed until there is a better chance of success. A stretched version of the stage is also planned for flight next year, which uses the same guidance and control system, so these follow-on Blue Star Mk.2 flights could also be at risk.

The Nuclear Test Ban Treaty is ratified, which prohibits the signatories from conducting further nuclear testing in the atmosphere or in space. The UK, USA and USSR sign, France does not. British plans for a further series of tests, codenamed Grapple-L, are cancelled. It is believed that these were to be conducted in late 1963 and used to prove new warhead designs. [Mention is also made in declassified documents of a plan to use a Blue Streak missile to launch a warhead for a high altitude test to investigate electromagnetic effects].


Sep-63
The Selene Project Committee (SPC) is formed to co-ordinate the management of the project.
12 committee members from France and the UK, plus an Australian observer, will serve to agree strategies, contracts and liaise with their respective governments on budget matters.

The USA completes the withdrawal of Thor missiles from the UK, leaving the missile defence of Britain solely to the few Blue Streaks that are operational. With the ongoing agreement of the British government, USAF aircraft equipped for nuclear delivery will remain stationed in the country.

Despite British efforts to dissuade them, French engineers are still keen on the idea of a nuclear thermal rocket as a shortcut to building a highly capable launch vehicle. British engineers know that the US has had limited success in building these nuclear engines. They have encountering significant problems with the Uranium based fuel elements melting, eroding or reacting with the hot Hydrogen gas, while the need for radiation shields and high temperature alloys means all the designs have a very low thrust/weight ratio.
The British are still cautious about revealing the exact details of Black Anvil performance to the French, although they do suggest that a cluster of these rockets topped by a large upper stage would result in a sufficiently powerful launcher, with no need for nuclear engines.

Ferranti are awarded a Selene Project contract to develop a digital computer to control a spacecraft.
Their successful bid builds on work done with the University of Manchester over the past few years. Unlike previous systems used on missiles and spacecraft, this will be a "general purpose computer", as opposed to a unit designed for a single function such as guidance or thruster control.

After extensive consultation with the government over secrecy issues, BAC publish a brochure for the "Silver Star" launch vehicle, which in practice is a Black Anvil missile with a new upper stage. Although the brochure and related press articles contain photographs and diagrams, many technical details are deliberately vague, with figures for the size and mass of the first stage showing it to be smaller than in the real design. There are no details of engine performance. BAC excuse this on the basis that the whole system is still in the design stage, so exact performance cannot be specified. However, it is quoted as being "greater than 4,000lbs" to Geostationary Orbit.

BK105
UK-only test flight of an advanced RV design using a spare Black Knight rocket left over from the UK-US "Gaslight" programme. A specially ballasted RV is used to provide an aerodynamic lifting effect. It makes an adequately stable re-entry and is recovered with most of the planned data.


Britain and the US conclude an agreement to continue research flights as part of a new test programme called "Crusade". This will test the radar and thermal characteristics of RV designs as a part of US efforts to develop an ABM system and joint US-UK research into decoys and low-observability RVs. Continued research will help to maintain US-UK technical links, despite the two countries' recent disagreements over deterrent forces. Six improved Black Knight Mk.3 vehicles will be built to support the flights, based on the new “stretched” Blue Star Mk.2 upper stage.

The GPO christen their TV satellite programme “Hermes”.
Baulking at the cost of American made solar cells, and with no British alternative likely to be available in time, Hawker Siddeley decide to use a thermal generator to power the satellites. Solar cell costs for small scientific satellites are bearable, but Hermes will require several kilowatts of power, far beyond any solar installation built to date and likely to cost nearly $1,000,000 per spacecraft – for the solar cells alone. The idea of this much hard currency leaving the country just for a few “panels” is not popular with the programme’s government backers. By contrast, a thermal generator could be developed in the UK for about £250,000 with a per-unit cost of around £50,000. Three spacecraft are planned and there are hopes for follow-on and export orders, so the cost savings are be significant.
Traditional steam plant technology is far too heavy and awkward to use on a satellite. The solution is planned to be a Brayton cycle, a closed-loop gas turbine which will use Nitrogen or Argon as the working fluid. There will be large, lightweight mirrors to focus sunlight onto heating elements on the sides of the satellite. The disadvantage of the system is that these mirrors must be pointed accurately at the sun (within about a degree) and relatively large and heavy radiators will be required to reject waste heat to space.


Oct-63
OTR-3
Blue Streak operational Test & Training flight from Woomera. Impact 2,350' from target point, range 1,167km. Successful flight.


BAC complete the preliminary design for the structure and mechanical systems of the Black Anvil missile. The Bristol Siddeley main engines are yet to be finalised, however the mechanical interface and connections have been agreed. The firm has built a full scale engineering mockup (mostly constructed of plywood). The awesome size of the missile is unveiled to service chiefs and ministers at a closed event at Filton.
The same day, the first converted Princess flying boat takes off from the Solent for a two hour test flight. These giant boats will be able to transport a complete Black Anvil missile tank on their backs, although no external load is carried on this first flight.

Prime Minister Harold Macmillan resigns on health grounds. His administration has been struggling to survive criticism and scandal since the start of the year.

The results of the investigation into the Blue Star second stage reveal no systematic failures in the design. So far, all the faults have been different and it is accepted that development programmes will always run into teething problems. However, improved testing of electrical systems is suggested as well as revised designs to cope with static discharges and temperature variations. Flights of the Mk1 stages may resume once additional insulation is installed and further quality control checks are completed.

British firms seek to increase their advantage in the competition to build the manned capsule that will carry Selene Project astronauts. A group led by Hawker Siddeley agrees to fund the use of two Black Knight Mk3 rockets to conduct high altitude, high speed entry tests of small scale capsule designs. The experience of the UK (and HSD in particular) in designing warhead RVs and their heat shields makes the firm a natural candidate for the contract to build the Selene capsule. It is hoped these tests will prove the viability of one or both of the blunt-based shapes under consideration.

British and French teams agree the design for their first joint satellite, which will be launched next year on a Blue Star rocket. To save time and cost it will be based on the design of Britain's first satellite "Ariel", but will include several French-built experiments. Use of the SUS stage will allow a higher and much longer lived orbit to be achieved. The primary British experiments are to be communications and control tests, while French experiments will investigate highly charged particles, micrometeoroid density and magnetic fields.
Despite having signed up to the Selene Project, the French government decides to press ahead with a programme for its own small satellite launcher. Called "Diamant", this follows on from an existing series of “Precious Stone” research rockets, similar in concept to Britain’s Black Knight. These will be developed into a vehicle capable of launching a 100kg payload into low Earth orbit. It is hoped that experience gained in building this vehicle will allow France to work with the UK on a more equal technical basis as well as provide a testbed for France's ballistic missile programme.

Bristol Siddeley are contracted to produce a flightworthy version of their J-650 demonstration engine to power the upper stage of BAC’s Silver Star launch vehicle. This is not as simple (or cheap) as it sounds, as the firm will need to produce a lightweight thrust structure and complete turbine/turbopump package, neither of which have been fully developed as part of the experimental engine programme.


Nov-63
A dock for Princess flying boats is completed near the mouth of the River Avon, about a mile from the airfield at Filton where Black Anvil boosters are to be built. A wide taxiway extends beyond the existing runway to the new M5 motorway, which has been built with special wide access points and a minimum of 30' overhead clearance to allow the large boosters to pass underneath.

Bristol Siddeley test fire a rocket engine on a converted Blue Streak test stand at Spadeadam as part of the "Orion" programme. The engine is purely experimental and will help in the development of the injector and turbopump assembly. This first test was intended to last 4 seconds but was aborted after 2.47s due to flow rates being lower than expected. Subsequent inspection of the chamber shows damage to both the injector and chamber cooling tubes. It appears fortunate that the test was stopped early while the engine was still intact. Loss of this hand-built test article could have set the programme back by months. An intact chamber makes analysis of the issue easier as there is no need to reconstruct the pieces first (or to rebuild the test stand).

F-18
Blue Star flight from Woomera in support of the Black Anvil development programme.
This time, the launch goes well and the SUS achieves a near-perfect 76 degree 257km circular orbit. The objective of the flight is to test navigation systems and sensors installed in a unit on top of the SUS stage.
Shortly after injection into orbit, the horizon, star and lunar limb sensors as well as a magnetometer are initialised and attempts are made to point them at their targets. Problems begin when the SUS stabilisation systems fail 97 minutes into the flight, leading to a total loss of attitude control. Without a stable and controllable stage, the sensor tests cannot be continued. Communication links are maintained with the stage and an experimental gyro test continues until T+17h 13m, when the SUS batteries are depleted. The mission report describes the flight as a “partial success”.

Nov-63 Overseas
A report on the mishandling of intelligence prior to the failure of negotiations at Nassau is delivered to President Kennedy.
Senior figures in the administration had insisted on a policy of complete US control over all nuclear weapons. Junior staff were used to supply evidence to support this policy, based on selective use of intelligence that pointed to Britain's lack of capability in missile and nuclear technology. Plenty of data on the true size and scope of the British missile programme was available, but was selectively ignored. The report goes on to suggest that the US should engage with the UK in the development of strategic missile technology, as this is likely to be of benefit to both sides.
As ever, the President has a busy day and the report remains on his desk as he departs for Dallas. Subsequent events ensure that it is forgotten.
 
so nice Lunar Surface Refueling sound, it not work well

NASA study it under JPL in beginn of 1960s

There idea was to land Solid rocket motors on Moon collect by remote controlled Rovers
and Assembly to return space craft with a Capsule, ready to wait for landing of One US Astronauts
but the Idea was dumped because, it's complexity of dozens launches and use of Rovers to assembly it.

There were also proposal of landing "Tanker" on Lunar surface to refuel the lander for return trip
That idea was dumped also on simple problem: what if the Lander land to far from Tanker and refuel hose is to short to cover the distance ?
Also to make the Tanker moveable was to problematic, do unknown roughness Terrain on Moon.

In the end NASA take Lunar Orbit Rendezvous it reduce the Payload to land on Moon by keeping Capsule and it's return fuel in orbit
dropping 60000 kg for Direct lander to 15200 kg for LOR

I think that Selene work better with Lunar Orbit Rendezvous !
Only question what for a lander ?
Apollo used Lunar Module with mass of 15200 kg for tow astronauts
L3-Complet used Lunniy Korabl, with mass of 6525 kg for one Cosmonaut

but there were study for more minimalist lander
in september 1961 James Chamberlin came up with a plan to use a Gemini capsule to land two men on the moon and return them safely to earth at a cost 1/20 of that of the Apollo project !
it use Gemini Capsule and 4372 kg Lander, it more rocket scooter were Astronauts sit in there spacesuit in open space.
That around 13000 kg to launch to Moon if they using cryogenic Lox/LH2 stage to brake into lunar orbit.
 
so nice Lunar Surface Refueling sound, it not work well
...
I think that Selene work better with Lunar Orbit Rendezvous !
Only question what for a lander ?

This story isn’t going to be “Britain and France do the Apollo Moon landings”. It will be different to that due to the very different circumstances (and this supposed to be “alternative history”; simply retelling real history would be a bit dull wouldn’t it).

There are lots of ways of going to the Moon – EOR (called EOM in the story), LOR, Direct Ascent, LSR or depots in Earth/Lunar/L1/L2 halo orbits to name but a few. All of them have both advantages and drawbacks; there is no “one right way” of doing it.

In reality, LOR was ultimately picked by NASA because they were already developing a rocket large enough to launch it in one go (versus two launches needed for EOR, which was their earlier preference). They were rushing to meet a deadline and had a blank cheque for development funds. All this fitted in with single-launch LOR quite well.
None of that applies to Selene – they don’t have unlimited funds, they’re not in a hurry, they don’t have a giant rocket in development and the goal is to “explore” the Moon (with the “unspoken” option of placing nuclear weapons on it).
We don't even have a mission mode or a manned spacecraft yet, so the design of a manned lunar lander is still some way off.
Where possible, Selene needs to work with whatever Britain and France have, or what is needed by other space and missile programmes – so expect to hear a lot more about “Black Anvil”. More details of that to follow in the next instalment.
 
Arthur Clarke Vindicated

Arthur C. Clarke had a series of stories in which the UK was most successful in space exploration as an endeavour not dependent on the US programe.

Congratulations, you have come up with a timeline which vindicates Sir Arthur's optimism.
 
So DynaSoar isn't cancelled properly, so I guess we may see earlier proper exploration of space planes, which might spur similar movement in the USSR
 
This story isn’t going to be “Britain and France do the Apollo Moon landings”. It will be different to that due to the very different circumstances (and this supposed to be “alternative history”; simply retelling real history would be a bit dull wouldn’t it).

There are lots of ways of going to the Moon – EOR (called EOM in the story), LOR, Direct Ascent, LSR or depots in Earth/Lunar/L1/L2 halo orbits to name but a few. All of them have both advantages and drawbacks; there is no “one right way” of doing it.

ok
but make sure that LSR has tanker stage that are moveable, mean wheels on landing legs and good tractor to pull the tanker to return stage.

Many thanks, hopefully he would have been optimistic about "The Project" too.

Plenty of technical detail with the next two posts, but a few pictures to go with it.


The Silver Star Launch Vehicle

From the very beginning of the programme, it was obvious that the Black Anvil missile could form the basis for a very capable space launcher. However, in 1961, Britain didn’t have the need for such a powerful rocket. The Blue Star launcher (a Blue Streak with a set of upper stages) would be adequate for any of the small scientific satellites that were being considered.

When designs for geostationary communications and broadcast satellites started to be considered in 1962, it was immediately obvious that Blue Star was not going to be powerful enough. Understandably, technical and official scepticism for these “relay satellites” took more than a year to overcome, during which time several respected British firms and institutions had developed more detailed specifications. By the middle of 1963, the basics had been worked out and all but the hardened sceptics were convinced that the idea (now called “Hermes”) could be made to work. Engineers would need to put a powerful transmitter in orbit, which meant a large and heavy satellite. Launched in June 1963, the experimental American “Syncom” satellite had a mass of about 90lbs in orbit. Hermes’ mass would be more like 5,000lbs.
In 1963, there were no rockets powerful enough to orbit this payload … but by 1967, there could be.

It wasn’t just pie-in-the-sky fantasy for engineers to think about these large satellites. Several firms involved in the preliminary designs for Hermes were also building Britain’s new ICBM, Black Anvil, and they knew what it would be able to do. With government backing and equipped with an upper stage, the mysterious “Black Anvil” missile could become the very public “Silver Star” launch vehicle.

For an ICBM, Black Anvil was huge. With an upper stage, Silver Star would be even bigger; as big as NASA’s Saturn 1, a lot heavier and much more capable, thanks to its 2½ stage design.

The first stage booster (the missile core of Black Anvil) will be 20' in diameter, 119' long and equipped with seven Bristol Siddeley Orion engines. At liftoff, it will generate 2.3 million pounds-force and carry 680 tons of liquid Oxygen and Methane fuel. A ring of 6 "booster engines" will help lift the rocket off the pad and accelerate it to around 6,000mph, before being jettisoned about 2½ minutes into the flight. A central "sustainer engine" will run from launch until it is shut down at a pre-programmed velocity, shortly before the core runs out of fuel.

On top of the booster, the Silver Star Upper Stage (SSUS) will be a short, fat tank equipped with a single J-650 Methane-Oxygen engine. Under the control of its own separate guidance system, this stage will inject itself into orbit, stay there until it is in the correct position then fire again to push the payload towards its destination. On geostationary flights, this would be reached about 6 hours later, when the stage would have to fire for a third time in order to put the payload into a circular orbit about 35,900km above the Earth. Once its job is done, the stage will eject the payload and switch itself off.

The design of the Silver Star would be a mixture of cutting-edge technology where it was needed, and use proven ideas where possible.
Many of the systems, actuators, hydraulics and electrics are quite “ordinary” (insofar as that word can be used for anything attached to a space rocket). The fuel tanks that make up the body of the missile are thin stainless steel shells that will only be held rigid by the gas pressure inside. This extremely lightweight arrangement is scaled up from Blue Streak (where it was copied from the US “Atlas”). Unlike most contemporary rockets, the gasses used to pressurise the tanks would be the same as the liquid fuel inside. Heat exchangers mounted on the engines will vaporise liquid Oxygen under pressure and feed it back to the LOX tank. Methane gas will be tapped off from the engine’s cooling circuit and fed back into the fuel tank. The arrangement saves weight and complexity by eliminating the need for separate Nitrogen or Helium tanks to pressurise the rocket.

The Orion engines are definitely not “ordinary”. They are the first large Methane-Oxygen rockets ever built, and the list of engineering firsts didn’t stop there. Chamber pressure, efficiency and engine cycle were higher and more exotic than any booster engine that had been built before.

The key to this performance is the “pre-heater” cycle. Engineers at Bristol-Siddeley had studied the “expander cycle” design of the Pratt and Whitney RL-10 (a small Hydrogen fuelled engine being built in the US) and thought that they could adapt it. The RL-10 works by using its Hydrogen fuel to cool the nozzle and combustion chamber. Once it has done so, it is “warm” (a relative term, as its still at about -100C). However, this is sufficient to expand across a turbine and produce enough power to run the pumps that pressurise the cold, liquid fuel in the first place. The act of cooling the engine is therefore used to keep the engine running. The idea works extremely well, but can’t be used to build Hydrogen fuelled engines much above 60-70,000lbs thrust.

By using liquid Methane, which is much denser and easier to pump than liquid Hydrogen, it would be possible to build a much larger engine using the same basic idea. A sub-scale demonstrator, the J-650, would be built to test the concept. It was perhaps fortunate that low turbine and pump efficiencies and lower than expected cooling requirements forced a rethink, ultimately leading to the design of Orion, one of the finest booster engines ever built.

Turning Swords into Ploughshares - Part 2

Bristol-Siddeley’s problem was that the cooling loop didn’t quite provide enough power to the pumps to meet the chamber pressure and thrust requirements. The solution was to pre-heat the Methane flow before it entered the turbines. Today, this arrangement would be called “staged combustion”, but the way it was done in Orion remains unique. It would be easy to raise the temperature of the Methane stream; just inject a bit of Oxygen and allow it to burn. However, the small rise in temperature needed would mean a very “rich” fuel burn. As anyone who has run their car’s engine too rich knows, this creates a lot of soot – unburned particles of carbon that get in everywhere and gum up the works. In a rocket engine, this effect can be very serious; clogged injectors, eroded turbine blades and hot spots can lead to explosive failures in a matter of seconds.

They would solve the soot problem by borrowing a design from their jet engine business and turning it on its head. Unlike a jet engine, where a small amount of fuel needs to be burned efficiently in a large amount of air, in this “pre heater” a small amount of Oxygen would need to be combusted in a large amount of fuel.
After cooling the nozzle and thrust chamber the gaseous methane (now at about 330K) would pass through the “pre-heater assembly”. Inside is a set of tiny combustion chambers which burn small amounts of Methane and Oxygen under much leaner conditions, producing no soot. The main Methane flow bypasses these chambers, cooling their walls before mixing with the very hot gas produced inside.

The effect of all this is to raise the amount of energy available for the turbines by heating the Methane stream to about 600K, allowing both thrust and chamber pressure to be increased. The result should be a highly efficient (albeit rather heavy) booster engine which will also function efficiently at high altitude. Orion could now be developed to deliver its planned 150tf thrust at liftoff, at a chamber pressure of 85bar. Specific Impulse (a measure of propulsive efficiency) would be 288s at sea level and 336s at altitude. Although this adventurous piece of design would suffer several setbacks during development, no other booster engine would come close to matching these numbers for years to come.

Bristol-Siddeley would also get to build their “expander cycle” engine. The small J-650 operated at low thrust and so didn’t need the pre-heater. It would go on to be developed into the engine that powered the Silver Star Upper Stage.

With these concepts finalised and with testing well under way, by the end of 1963 designers at BAC were increasingly confident that this combination of engines and stages would be able to inject a 3 ton payload into geostationary orbit, large enough for the GPO’s new relay satellites.
It would be able to throw even larger probes towards the Moon.

Whooo i'm impressed !

The Black Anvil data of 20' in diameter, 119' long and with 2.3 million pounds-force take off thrust
means Britain just build there version of Proton rocket !
also the use of methane is surprising me, i had expected Kerosine/H2O2 engine with Staged-combustion (high Pressure and High Thrust).
