Ustinov supported presentation of the DOS concept to the Central Committee. Chelomei categorically opposed DOS and was trying to kill it through military channels. But the allure of an '18 month' station - one which would not only beat the American Skylab, but be in space in time for the 24th Party Congress - seemed too alluring. Mishin also rejected DOS, but deputies at both design bureaux supported the concept and were eager to proceed.
DOS was therefore created only when the moon project failed. Chelomei was forced to work on DOS, and it severely impacted Almaz schedules. The Salyut name was later applied to both the DOS and Almaz stations, creating the impression in the outside world that they were built by one designer.
Progress M-62 (27P), approaching from below the station, docked nominally at the DC1 Docking Compartment nadir port at 3:14am EST, with automatic AO-VKA orientation antenna retraction, followed by docking probe retraction and hook closure ('sborka') at 3:23am after motion damp-out, while the ISS was in free drift. (Launched 12/23 (2:12am EST), the 27P resupply drone delivered about 2.5 tons of cargo for the ISS crews, including propellants for the Russian thrusters, fresh water, oxygen, food, spare parts, repair gear, life support and science experiment hardware. For the docking, ISS attitude control authority was handed over to Russian MCS (Motion Control System) thrusters at 11:48pm and returned to US Momentum Management at 5:06am. Starting with TV camera activation at ~2:37am (range ~8 km), the KURS TV camera display data overlay failed to show through docking despite attempts by the crew to activate the numerical display. The docking took place nominally, without violation of any joint flight rules, since Malenchenko and Whitson had all numerical data on a laptop before them. Telemetry was also available in TsUP-Moscow.) Additional Details: ISS On-Orbit Status 12/26/07.
