The Army Ordnance Missile Command (AOMC) submitted the "Saturn System Study" which had been requested by the Advanced Research Projects Agency ARPA on December 18, 1958. From the 1375 possible configurations screened, and the 14 most promising given detailed study, the Atlas and Titan families were selected as the most attractive for upper staging. Either the 120-inch or the 160inch diameter was acceptable. The study included the statement: "An immediate decision by ARPA as to choice of upper stages on the first generation vehicle is mandatory if flight hardware is to be available to meet the proposed Saturn schedule." Additional Details: Saturn System Study. References: 16 .
The first stage of the Saturn SA-5 launch vehicle was static fired at MSFC for 144.44 seconds in the first long-duration test for a Block II S-1. The cluster of eight H-1 engines produced 680 thousand kilograms (1.5 million pounds) of thrust. An analysis disclosed anomalies in the propulsion system. In a final qualification test two weeks later, when the engines were fired for 143.47 seconds, the propulsion problems had been corrected. References: 16 .

Mir Main Expedition EO-01. Epic repair mission. Crew comprising ship's commander L D Kizim and flight engineer V A Solovyov first docked with the Mir orbital station to conduct scientific and technical studies and experiments. Mir then maneuvered 17 April to match Salyut 7 at 4000 km separation, then again on 4 May to catch up. After six weeks aboard Mir, Soyuz T-15 undocked on 5 May, then rendezvoused with the dead Salyut 7 station. Only docking to date by a single spacecraft with two space stations. After manual docking with inoperative Salyut 7, the station was found to be ice bound and without electrical power. Crew repaired the station, regaining power, heat, and environmental control. Removed experimental results left behind by last crew. Undocked Salyut 7 on 25 June, and redocked with Mir on 26 June. Landed 55 km NE Arkalyk. Recovered July 16, 1986 12:34 GMT. No crew ever revisited Salyut 7; it made an uncontrolled reentry over Argentina. References: 1 , 2 , 6 , 32 , 33 , 51 .

Second test against a Minuteman I was considered successful enough that no further tests were planned. Further develoment of the technology was to be accomplished by the Orbital Sciences' Aries test vehicle with spectacularly poor results.
