The original draft project anticipated use of a two-launch profile. On the first launch a Block R TB braking stage would be put on a translunar trajectory. The TB would place itself in lunar orbit. Next, the manned L3M lunar lander would be launched. This new spacecraft was much larger than the LK, with a mass of 21 tonnes landed on the lunar surface. The L3M would dock, tail-first, with the TB stage in lunar orbit. The RTB would act as a lunar crasher stage. The L3M would separate from the TB just over the lunar surface, then hover to a soft landing. The crew would spend up 16 days on the surface. Following completion of their work, the landing legs would be left behind, and the L3M would launch itself on a trans-earth trajectory. Just before arrival at earth, the crew would enter their Soyuz capsule, separate from the L3M, and make a lifting re-entry into the earth's atmosphere. It was felt that within the existing funding allocation of the original N1-L3 programme, enough N1's would be available to support a series of landings in 1978-1980.

Growth of the 12-man Saturn V-launched Space Station into a 50 man Space Base was a required capability in the Phase B NASA Space Station studies of 1969-1970. The original core Station Module was to be used in the Base build-up several years later or was to be used as a prototype of one of the Space Base modules. Space Base would serve as a major international facility for research, applications and for the support of other space operations such as servicing unmanned satellites.

NASA had canceled the Apollo 20 mission and stretched out the remaining seven missions to six-month intervals, Deputy Administrator George M. Low told the press in an interview after dedication of the Lunar Science Institute (next to MSC in Houston). Budget restrictions had brought the decision to suspend Saturn V launch vehicle production after vehicle 515 and to use the Apollo 20 Saturn V to launch the first U.S. space station in 1972. References: 16 .

NASA issued instructions for deletion of the Apollo 20 mission from the program. MSC was directed to take immediate action to:

• Stop work on LM-14 and determine its disposition.
• Delete requirements for the Apollo 20 spacesuits and portable and secondary life support systems.
• Determine disposition of CSM 115A pending a final decision as to its possible use in a second workshop mission.
• Reevaluate orbital science experiments and assignments and prepare proposed revisions.

Dale D. Myers was appointed NASA Associate Administrator for Manned Space Flight with an effective date of 12 January. He succeeded George E. Mueller, who left NASA on 10 December 1969 to become a vice president of General Dynamics Corporation. Prior to his acceptance of the NASA position, Myers was Vice President and General Manager of the Space Shuttle Program at North American Rockwell.

An MSC meeting to realign the Apollo 16-19 lunar orbital science experiments recommended that the Sounding Radar Experiment, S-167, be deleted and the Lunar Electromagnetic Sounder, S-168, should be developed and flown. Scientific-value for the experiments was ranked in the following descending priorities for the various scientific disciplines: geochemistry, particles and fields, imagery and geodesy, surface and subsurface profiles, and atmospheres.

Australis-OSCAR 5 was launched piggyback with ITOS-1 (TIROS-M weather satellite. Weight 17.7 kg (9 kg of which was battery mass). Box shaped 304 x 431 x 152 mm. 2 meter monopole and 10 meter dipole antennas. It was the first amateur satellite to be remotely controlled. Built by students at The University of Melbourne, Melbourne, Victoria, Australia. Battery powered, Australis-OSCAR 5 transmitted telemetry on both 2 meter (144.050 MHz at 50 mW) and 10 meter (29.450 MHz at 250 mW) bands that operated for 23 and 46 days respectively. Passive magnetic attitude stabilization was performed by carrying two bar magnets to align with the Earth's magnetic field in order to provide a favorable antenna footprint. The University of Melbourne compiled tracking reports from hundreds of stations in 27 countries. References: 1 , 2 , 5 , 6 .

Brezhnev orders a cooperative crash program to build a civilian space station to beat Skylab into orbit. The civilian station (later named Salyut) will use the Almaz spaceframe fitted out with Soyuz functional equipment. Mishin's OIS military station was cancelled and Chelomei's Almaz would continue, but as second priority to the civilian station. The Soyuz 7K-S station ferry, the 7K-ST, would be revised to be a more conservative modification of the Soyuz 7K-OK. The OIS cosmonaut group was incorporated into the Almaz group. References: 76 .

NASA announced that the Apollo Applications Program had been redesignated the Skylab Program. The name Skylab, a contraction connoting a laboratory in the sky, was proposed by Donald L. Steelman, USAF, while assigned to NASA. The name was proposed following an announcement by NASA in 1968 that they were seeking a new name for AAP. Then NASA decided to postpone renaming the program because of budgetary restrictions. Skylab was later referred to the NASA Project Designation Committee and was approved 17 February 1970.
