Update #35 Starting the new year, American-style
This update is a bit of an experiment, approaching 1970 holistically rather than piecemeal. It means a longer prep time, but then regular updates.
The Soviet moon landing meant a new breath of life for the American space budget. A Congress that had sharpened its knives and licked its chops at the chance to cut space pork and hand it over to welfare recipients (as proposed by many Democrats), more worthy defense projects (proposed by many Republicans), or back to the People, themselves (proposed by an overshouted minority in both parties), now had to reevaluate their plans.
The Space Race wasn't over, and there was concern that, despite the rise of detente in the past couple of years, America's soft stance on Communism had given the Soviets time to regroup and surpass the West. Moreover, it wasn't just about prestige anymore--it was about seizing the higher ground.
NASA was quick to capitalize on the short-lived new phase of Moon Fever. If the civilian program was to survive well into the 70s, it was going to have to evolve beyond annual expensive moon shots. To that end, Director Webb concentrated on enhancements to the Saturn line. In addition to the Saturn II, a modular successor to both the IB and V lines, work was also done on the truly massive Saturn V Mark 4, which would throw 500,000 kg into orbit in a single throw. The mammoth rocket would require an overhaul of the entire Canaveral infrastructure but would actually be more efficient, ultimately, than the launch of three or four contemporary Saturn Vs. The plan was to be able to launch really big space station components by mid-decade, design of which began in 1970.
And there is no question that NASA was committed to its station program. In addition to maintaining its successful (if utilitarian) Asgard stations, NASA contracted Boeing set to work on a successor. It would be a modular system for easy upgrading. The first module designed was a fuel station, so Artemis support could be maintained. This modular station was designed to be compatible with the ministations concurrently being developed (though by a different and, unfortunately, slower contractor--McDonnell Douglas). Part of the ministation's delay was the result of emphasis being put on adaptability for its role as part of a Martian spacecraft.
Boeing also began designing 15-ton lunar base modules along similar lines to its space station components. Essentially, NASA's station policy mirrored its Saturn policy--maximum modularity for maximum cost efficiency.
Supporting the station was a follow-on design of Artemis with a cargo bay and manipulator arms instead of the big SM fuel tank. Even with the budget boom, this project was a design too far, especially given the flexibility and relative inexpensiveness of the Delphi-derived Thor. Cargo Artemis ("Ceres") never went beyond the initial plan stage, and it quietly disappeared from the 1971 budget.
One promising plan evolution of existing hardware, however, as an unmanned Artemis derivative designed to bring 15 tons of supplies or a 15 ton base component to the moon. Because the vessel did not have to support astronauts or return to Earth, a mission could be launched with a single Saturn V.
The last big project started by NASA was a study of a reusable winged spaceplane. Excitement for the project was rather lukewarm, but a cheap multi-mission alternative to the Artemis and aging Delphi was a good idea, at least on paper. Max Faget's stubby-winged concept was the most popular configuration at the time.

Coasting the wave of increased funding that resulted from the Soviet moon landing, the Department of Defense diversified its pursuits. The thinking was that, if their eggs were put in enough baskets, at least some of the programs would survive a future budget cut.
One of the most ambitious projects was Argo, a follow-on spaceplane utilizing technology pioneered by the X-20 programs, but involving a whole new design. The goal was to develop a partially or fully reusable spaceplane which would combine heavy lift capability with the flexibility of the Dynasoar. It would hopefully be cheaper than anything NASA could build, potentially replacing Artemis and Delphi derivatives. It could deploy satellites and retrieve (friendly and enemy) satellites for inspection back home. Initial plans involved a two-plane, fully reusable system. Both would be liquid fueled and piloted. The first stage would take off with the second on its back and then return to Earth, while the second, roughly a scaled up S-23, would head off into orbit.
It was undoubtedly an ambitious project, one designed to replace the Titan booster family (and potentially cripple competitors using them) and to deliver large numbers of people into orbit. In addition to being able to carry seven passengers, the initial Argo design was usually depicted with a squad of "space marines" in the cargo bay.
Two mission profiles were to be unique to the new vessel. One was a single-orbit "once around." This would allow the spaceplane to do on-orbit work and deorbit before the Soviets could intercept. The Argo would have some 2000km of cross-range capability on landing.
The other profile involve carrying space-based weaponry into orbit for testing. This was completely illegal pursuant to the Outer Space Treaty of 1968, but it would also be difficult to confirm absolutely.
Most attractively, the Argo would be able to fly at least twelve times per year.
Another ambitious project, one that returned from the shelf, was the Phoenix 2-man space station to be launched into polar orbit optimized for constant visual and radar surveillance. Resolution of station cameras would be as good as .2m--better than the NRO's satellites of the time.
There would also be an attached spaceplane that could be used for bombing, surveillance, anti-satellite duties, etc. A geosynchronous station was also a possibility
Planned operational life for the station was 40 days. An S-23 Pegasus could bring enough provisions for an additional 40 days.
The Department even secured funding for a parallel lunar project. With each NASA landing requiring two giant Saturn Vs, it stood to reason (so Clark Clifford urged) that if one could put everything on a single Saturn V, or perhaps two cheaper Titan 3Ls, one could launch a very inexpensive lunar mission indeed. To do so would require a complete redesign of the lunar spacecraft, involving a version of the Lunar Orbit Rendezvous proposed almost a decade before. Lockheed and TRW were awarded contracts to develop a small lunar lander to attach to a stripped-down Artemis or some other craft. It was not quite a spacecraft without a mission--the Air Force liked the idea of a dedicated and cheap in-space vehicle for repair and station construction.
Work also continued on the Titan 3M, the Adonis space fighter as well as a transstage to make the Dynasoar family more flexible, and the Orpheus geosynchronous communications satellite.
Of course, DoD couldn't have everything, even in a boom year. And thus, the S-22 made its quiet final exit from the lists of extant military spaceplanes. No examples survive, all of the parts of existing or in-production vessels being recycled for S-21 use or scrapped.

Perhaps the biggest budget increase (percentage-based) in the wake of the Soviet moon landing went to the Office of Space Science. NASA's unmanned program had already shown it was on the way toward, if not directly turning a profit, increasing the profitability of the nation. The suspension of the Orbital Observatories program also freed up some funds.
In development at the OSS were the Advanced Exploratory Spacecraft: Solar (AES), the Mercury flyby probe, and two Martian-aimed endeavours: an improved Valkyrie orbiter and a bus-and-lander revival of the canceled Thurisoz based on the lunar Isa.
The lynchpin to OSS' success was its partnership with the National Reconnaissance Office (NRO). Using shared technology, the OSS' Earth Resources Technology Satellite (ERTS) and Lunar Geological Observer (LGO) satellites had already proven their worth. Director's Fletcher and Flax (OSS and NRO, respectively) watched each other's backs when Secretary of Defense Clifford argued for more manned flights (though even their best efforts could not defeat the tremendous publicity DoD would receive in latter 1970).

The NRO's paramount goal was determining whether or not the Soviets planned to return to the moon, and when. Resources were poured into intelligence programs both terrestrial and space-bound. At least one Soviet agent was turned into a valuable double (see "Checkmate", Knopf Press 1994). American attempts to infiltrate agents into the Soviet space and missile industries proved less fruitful--Andropov was still circling all the tents to keep America clueless about the Soviet's slow development of 2nd-strike nuclear weapons
Development continued on the geosynchronous versions of the Creon ELINT probe as well as the Ares orbital launch detection satellite. Work progressed on the next-generation Hebe satellite, which monitored nuclear tests. The ill-fated Athena real-time reconnaissance satellite continued to have troubles in development.
