  • NASA Headquarters approved rescheduling of the Gemini flight program as proposed by Gemini Project Office (GPO). - . Nation: USA. Spacecraft: Gemini; Gemini Parachute; Gemini Paraglide. Late delivery of the spacecraft systems coupled with the unexpectedly small number of Mercury systems incorporated in the Gemini spacecraft had forced GPO to review the flight program critically. In the revised program, the first flight was still set for December 1963 and was still to be unmanned, but it was now to be orbital rather than suborbital to flight-qualify launch vehicle subsystems and demonstrate the compatibility of the launch vehicle and spacecraft; no separation or recovery was planned. The second mission, originally a manned orbital flight, now became an unmanned suborbital ballistic flight schedule for July 1964. Its primary objection was to test spacecraft reentry under maximum heating-rate reentry conditions; it would also qualify the launch vehicle and all spacecraft systems required for manned orbital flight. The third flight, formerly planned as a manned orbital rendezvous mission, became the first manned flight, a short-duration (probably three-orbit) systems evaluation flight scheduled for October 1964. Subsequent flights were to follow at three-month intervals, ending in January 1967. Rendezvous terminal maneuvers were planned for missions 3 (if flight duration permitted) and 4, a seven-day mission using a rendezvous pod. The sixth flight was to be a 14-day long-duration mission identical to 4 except that no rendezvous maneuver missions with the Atlas-launched Agena D target vehicle. Water landing by parachute was planned for the first six flights and land landing by paraglider from flight 7 on.

The two crewmen were to transfer to the Pecan for the duration of the mission. As with similar investigations for the application of Apollo hardware, the scheme postulated by Robins and his colleagues emphasized maximum use of existing and planned hardware, facilities, and operational techniques.

1975 April 29 - . LV Family: Proton. Launch Vehicle: UR-500MK.
  • UR-500MK designed - . Nation: USSR. Related Persons: Chelomei; Glushko. In response to the Ministry of Defence's guidelines for third generation launch vehicles, the Ministry of General Machine Building issued instructions for Chelomei to study boosters meeting the military's requirements. These included Lox/Kerosene propellants in place of the toxic N2O4/UDMH favoured previously. Chelomei's competitor in the design, Glushko, was then head of NPO Energia which included Glushko's former OKB-456 engine design bureau. Therefore Chelomei was forced to propose using Kuznetsov Lox/Kerosene engines from the cancelled N1 moon program. The use of existing Proton tankage tooling for the stages and the Kuznetsov engines would allow a high-performance vehicle to be developed at minimum cost. However Chelomei was out of favour, Kuznetsov was discredited after the N1 fiasco, and Glushko was ascendant. The proposal stood no chance. Glushko's Zenit launch vehicle became the accepted solution.

  • ISS On-Orbit Status 04/29/08 - . Nation: USA. Related Persons: Kononenko, O D; Love; Reisman; Volkov, Sergey. Program: ISS. Flight: ISS EO-16-3. CDR Volkov worked a major IFM (Inflight Maintenance) in replacing the compressor unit of the Russian SKV-2 air conditioner with a spare, after first verifying deactivation of SKV-2 and the associated NOK-2 condensate evacuation pump.

    The separation & reconnection of hydraulic lines required several leak checks during the IFM. The activities were supported by tagup with ground specialists via S-band and photo documented. (The SKV-2 shut down yesterday morning due to high temperature, but the compressor R&R had already been scheduled for some time.)

    With the BITS2-12 onboard telemetry system's still disconnected at the SKV-2 and the Elektron ST-64 current stabilizer (BD-SU control mode remaining active), FE-1 Kononenko replaced the ST-64 with a spare unit to check out the latter's operability. Later, Sergey & Oleg reconnected the BITS2-12, and the Elektron was restarted in 32A mode by the ground, with Kononenko monitoring the external temperature of its secondary purification unit (BD) for the first 10 minutes of operations to ensure that there was no overheating. The activities were supported by tagup with ground specialists via S-band. (When the FE-1 disconnected the BITS2-12 telemetry connector at the ST-64, an 'SM Elektron Catastrophic Failure' alarm alerted the crew but was quickly identified by TsUP-Moscow as having been generated by erratic data caused by the cable disconnection. The message was unexpected since it had not annunciated previously in ground tests of the R&R.) Additional Details: ISS On-Orbit Status 04/29/08.
