55 lat temu, 24.06.1968, zakończył się test 2TV-1 w ramach sprawdzania kryteriów bezpieczeństwa zmienionych po wypadku załogi Apollo 1.

Załoga testu składała się z 3 astronautów:
Josepha P. Kerwin  dowódca
Vance D. Brand pilot CM
Joseph H. Engle pilot LM.

Załoga w kombinezonach kosmicznych Apollo A6L , weszła do CM 16 czerwca 1968 roku.
Wg procedury atmosfera kabiny na początku testu była mieszaniną 60 procent tlenu i 40 procent azotu, a potem dopiero potem zastąpiono ją samym tlenem. Było to potem praktykowane w realnych lotach kosmicznych.
Załoga spędziła 177 godzin w CM.

After 177 hours in a CM within Chamber A of the Space Environment Simulation Lab at MSC Kerwin, Brand & Engle emerged OTD in 1968. The 2TV-1 test began on 16 Jun to evaluate systems & procedures upgraded since the Apollo 1 fire & in advance of Apollo 7 [Courtesy NASA/Mark Garcia]

50 Years Ago: Two Critical Apollo Tests In Houston

For the 2TV-1 test NASA selected astronauts Joseph P. Kerwin as Commander, Vance D. Brand as CM Pilot and Joseph H. Engle as LM Pilot.  The crew, wearing Apollo A6L space suits, entered the CM on June 16, 1968, and closed the spacecraft’s hatch.  Based on lessons learned from the Apollo fire and in accordance with NASA’s decision in March 1968, the cabin’s atmosphere at the beginning of the test was a mixture of 60 percent oxygen and 40 percent nitrogen at a pressure of 16 pounds per square inch.  Engineers then pumped Chamber A down to vacuum and replaced the cabin’s atmosphere with pure oxygen at five pounds per square inch, the same procedure followed in an actual spaceflight.

During the next eight days, the crew performed many of the functions as if on an actual spaceflight, including eating and sleeping.  They operated guidance and navigation equipment, activated and checked out spacecraft systems and simulated engine firings.   Meanwhile, chamber operators put the spacecraft through several phases of the thermo-vacuum test, beginning with a 15-hour hot soak with the arc lamps aimed at the CM, followed by a 15-hour cold soak with the lamps off.  Then they aimed the lamps at the side of the Service Module for 45 hours, followed by 71 hours of alternate and contingency operations, ending with a 12-hour entry phase.  The spacecraft performed very well throughout the test, with only a few minor anomalies reported.  The crew egressed from the spacecraft on June 24, having spent 177 hours in the CM.  Recommendations from the test resulted in 12 hardware design and 13 crew procedure changes for the Apollo 7 mission.

60 lat temu, 26.06.1963. odbył się pierwszy naziemny test silnika SPS (Apollo Service Propulsion System).
Podczas lotów silnik SPS zapewnił wymaganą zmianę prędkości w lotach ku Księżycowi i z powrotem na Ziemię.

60 Years Ago: First Test Firing of the Apollo Service Propulsion System

In March 1962, NASA selected Aerojet-General’s Space Propulsion Division in Azusa, California, as the subcontractor to design, build, and test the SPS engine, designated AJ10-137, at a time when the agency favored the direct ascent mode to reach the Moon. The design of the SPS ensured that it had sufficient thrust to lift the entire Apollo spacecraft from the lunar surface for the direct trip back to Earth. Even after NASA selected lunar-orbit rendezvous in July 1962, no longer requiring such a powerful engine, managers decided not to change the design for the SPS so as not to delay its development. To increase the reliability of the engine now needed for critical maneuvers, especially the trans-Earth injection burn to bring the astronauts home, NASA chose the use of Aerozine 50 as fuel and nitrogen tetroxide as oxidizer. As hypergolic propellants, meaning they ignited upon contact with each other, they did not require a complex ignition system and also had the advantage of long-term storability. The engine generated 20,500 pounds of thrust and the gimbalable engine nozzle allowed precise steering.
