Mercury ECS Chronology

1959 July 31 - .
  • First animal couch for the Mercury program. - . Nation: USA. Program: Mercury. Spacecraft: Mercury; Mercury ECS. Personnel from the Aeromedical Field Laboratory inspected the first animal couch fabricated by McDonnell to be used in the Mercury animal flight program. The objective of the animal program was to provide verification of successful space flight prior to manned missions; to aquire data on physical and mental demands which will be encountered by the astronauts during space flight; to provide dynamic test of technical procedures and training for support personnel in handling the aeromedical program for manned flight; and to evaluate spacecraft environmental control systems and bioinstrumentation under flight conditions.

1959 September 11 - .
  • Mercury astronaut food and water requirements - . Nation: USA. Program: Mercury. Spacecraft: Mercury; Mercury ECS. After a preliminary study of the Mercury environment with regard to astronaut food and water requirements, Dr. Douglas H. K. Lee estimated that water use would be in the order of 500 cu cm/hr and that the caloric intake per day would be about 3,200 calories of food. Dr. Lee was a member of the Natick Quartermasters Research and Engineering Laboratory.

1960 April 18 - .
  • Manned environmental-control-system training spacecraft completed - . Nation: USA. Program: Mercury. Spacecraft: Mercury; Mercury ECS. Summary: Fabrication of the manned environmental-control-system training spacecraft was essentially completed and a test program on the equipment was started at McDonnell. This test was completed on April 25, 1960..

1963 January 11 - .
  • Changes made to Mercury spacecraft 20 - . Nation: USA. Program: Mercury. Flight: Mercury MA-9. Spacecraft: Mercury; Mercury ECS. The Project Engineering Field Office (located at Cape Canaveral) of the Mercury Project Office reported on the number of changes made to spacecraft 20 (MA-9) as of that date after its receipt at Cape Canaveral from McDonnell in St. Louis. There were 17 specific changes, which follow: one to the reaction control system, one to the environmental control system, seven to the electrical and sequential systems, and eight to the console panels.

1963 April 20 - .
  • The final water condensate tank was installed in spacecraft 20 for the Mercury MA-9 mission. - . Nation: USA. Program: Mercury. Spacecraft: Mercury; Mercury ECS. In all, the system consisted of a 4-pound, built-in tank, a 3.6 pound auxiliary tank located under the couch head, and six 1-pound auxiliary plastic containers. The total capacity for condensate water storage was 13.6 pounds. In operation, the astronaut hand-pumped the fluid to the 3.6 pound tank to avoid spilling moisture inside the cabin from the built-in tank. Then the 1-pound containers were available.

1963 June 6-7 - .
  • Mercury MA-10 pitched to Webb - . Nation: USA. Related Persons: Webb. Program: Mercury. Flight: Mercury MA-10. Spacecraft: Mercury; Mercury ECS. Officials of the Manned Spacecraft Center made a presentation to NASA Administrator James E. Webb, outlining the benefits of continuing Project Mercury at least through the Mercury-Atlas 10 (MA-10) mission. They thought that the spacecraft was capable of much longer missions and that much could be learned about the effects of space environment from a mission lasting several days. This information could be applied to the forthcoming Projects Gemini and Apollo and could be gained rather cheaply since the MA-10 launch vehicle and spacecraft were available and nearing a flight readiness status.

1963 June 8 - . LV Family: Atlas. Launch Vehicle: Atlas D.
  • Mercury MA-10 environmental control system changes - . Nation: USA. Program: Mercury. Flight: Mercury MA-10. Spacecraft: Mercury; Mercury ECS. In preparation for the Mercury-Atlas 10 (MA-10) mission, should the flight be approved by NASA Headquarters, several environmental control system changes were made in spacecraft 15B. Particularly involved were improvements in the hardware and flexibility of the urine and condensate systems. With regard to the condensate portion, Gordon Cooper, in his press conference, indicated that the system was not easy to operate during the flight of Faith 7 (MA-9).
