Skylab
In October 1972 Kennedy Space Center gave a spectacular show: Two Saturn Vs rolled out VAB toward Launch Pad 39
One was Apollo 17, scheduled to launch on December 7th.
The Other was Skylab, America's (and the world's) first space station scheduled for Launch on November 23rd.
Skylab began in 1965 as the Apollo Application Program in MSFC under George E. Mueller
The first goal was launch a 3 man Space Station build from S-IVB stage called "The Orbital Workshop“ or OWS.
In 1968 with the termination of MOL program at the USAF, part of their Astronauts were transferred to NASA, several were assigned to the Skylab program.
Also the name was changed from "the Orbital Workshop“ into Skylab.
In 1970 McDonnell Douglas started to build in California, two space stations, Skylab A and B (B for backup).
Finally, in 1972 Skylab A arrived in late August at KSC for preparation to Launch.
While in Johnson Space center the second Mission Control Center was activated for Skylab, so the Apollo 17 Mission could go synchronous.
On November 23 the Saturn V took off from Pad 39-B, but 63 seconds later the Micrometeoroid shield detach and was ripped off the station
Skylab arrived in orbit and deployed the Apollo Telescope Mount and its Solar cells, while the main solar cells did respond on orders from ground control.
Also rise the temperature in Station released toxic fumes from material in the station.
This was a new Disaster for NASA, what to do ?
George E. Mueller was clear that the future of NASA was at stake, so he made a decision: the first Skylab crew must repair the station.
This delayed the launch for 10 days to prepare the Repair procedure.
In the mean time ground control had vented the Atmosphere of the station, purging it with pure Nitrogen four time, before restore the Nitrogen/Oxygen atmosphere.
Skylab-2
So on December 2, Skylab-2 was launch from Pad 34 on Board: Charles "Pete“ Conrad, Jr., Joseph P. Kerwin and Paul J. Weitz.
As they arrived 6 hours later at Skylab they saw the full scale of the problem,
The Micrometeoroid shield had also ripped off a solar cell of the station, the other was jammed by the debris of the shield.
The first EVA attempted to deblock the Solar Cells ending in failure as Skylab lost of most RCS fuel.
After docking the crew enter the station in spacesuits despite the high temperatures and being underpowered, Skylab was fine.
They used the Science Airlock to deploye a parasol, working as sunshade, with temperatures successfully dropping to an acceptable level.
On December 7th, Apollo 17 was launched and for the first time there were 6 American astronauts were in space .
On December 17th, with the second EVA Conrad and Kerwin managed to Open the solar wing on Skylab, providing electrical power for next two missions.
On December 24th, The Crew celebrated Christmas in Orbit, the first time since Apollo 8's historic mission that an Astronaut had spent Christmas in Space.
Then on December 30th, the Crew left Skylab and returned safely to Earth after a mission of 28 days.
Meanwhile Skylab was put into Hibernation for next Crew arriving in February.
Apollo 17
On December 7, a Saturn V manned with Eugene Cerman, Ronald Evans and Joe Engle, blasted off from pad 39-A.
500,000 people watching the spectacle of a Saturn V night launch, from over 200 km you could see the light of the five F-1 engine gleaming in the Sky.
During the transfer to moon the crew experienced light flashes in the spacecraft, cosmic radiation from Sun hitting the eyes of the astronauts.
On board were five pocket mice with radiation monitors implanted, to study the phenomenon, increasing with Solar activity.
Also reported by Cerman was a blinking object that follow the CSM/LM on large distance, later it was revealed to be radar, one of adapter panels was drifting parallel to CSM/LM
3 day later the CSM America and LM Challenger entered lunar orbit. The LM Challenger touched down in Taurus-Littrow right on target on December 11.
During the first EVA Cerman took panorama pictures of the landing side from the top of the LM hatch.
After a good night of rest the Crew started the Second EVA , Cerman's first words on moon were:
Quote:
"Joe [Engle] I'm out here oh my Golly! Unbelievable! Unbelievable; but is it bright in the Sun."
They offloading the rover and they deployed the ALSEP package and put US flags on the lunar surface.
A problem Cerman and Engle had on all EVAs was the moon dust, it stuck on suit, on the rover, even got inside there LM which Cerman and Engle described as the smell of spent gunpowder.
But they had their fun, during the EVA Engle and Cerman even start singing during this EVA.
On the third EVA Cerman and Engle collected 66 kilograms of Lunar samples.
The fourth EVA Engle made a big discovery near a bolder, a small unusual rock "The Genesis rock““
it came from lower crust of moon, being one of the oldest stones found on moon and showed traces of original lunar magnetic field !
On end of the EVA they parked the Lunar rover at a safe distance to film the accent of LM .
With the surface stay of 3 days and 3 hours it was a new record not to mention the EVA of seven hours 15 minute and the 110.4 kg of lunar samples.
During the time in lunar orbit, the CSM America scanned the Surface with spectrographs for the geological Lunar Map.
After dedocking the LM, the Crew released the PFS-2 subsatellite, this time the PFS-2 remain stable in it's orbit.
On return to earth, Ronald Evans made an EVA to collect the films from the SIM bay.
Apollo 17's crew manage to take a picture of the whole earth, "The Blue Marble" that become the most iconic picture of the 20 century.
Then the CM America splashed down save near USS Ticondergoa in pacific ocean on December 19th.
Aftermath:
Skylab 2 and Apollo 17 were successes for NASA, not only did they beat the Soviets in the space race with, dual mission of 6 astronauts, the biggest space station with 70 tons, it’s repair and a record 28 day stay of astronaut in space,
Apollo 17 again broke records on the Moon while Skylab-2 brought home 392 hours of experimental data on medicine, solar and Earth science.
While the Soviets had "The Empty handed Mission“ of Zond 17, it’s repeat with Zond 18 and delays in their Salyut projects.
This impress Capitol Hill, finally NASA had done it's job and had secured America's in the lead in Space Race for the moment
