Apollo 13 Faces CO2 Crisis in Lunar Module Until Scrubber Is Made (15 April 1970) —- An interior view of the Apollo 13 Lunar Module (LM) during the trouble-plagued journey back to Earth. This photograph shows some of the temporary hose connections and apparatus which were necessary when the three Apollo astronauts moved from the Command Module (CM) to use the LM as a “lifeboat”. Astronaut John L. Swigert Jr., command module pilot, is on the right. An unidentified astronaut on the left holds in his right hand the feed water bag from the Portable Life Support System (PLSS). It is connected to a hose (center) from the Lunar Topographic (Hycon) Camera. In the background is the “mail box,” a jury-rigged arrangement which the crew men built to use the CM lithium hydroxide canisters to scrub CO2 from the spacecraft’s atmosphere. Since there was a limited amount of lithium hydroxide in the LM, this arrangement was rigged up to utilize the canisters from the CM. The “mail box” was designed and tested on the ground at the Manned Spacecraft Center (MSC) before it was suggested to the Apollo 13 astronauts. An explosion of an oxygen tank in the Service Module (SM) caused the cancellation of the scheduled moon landing, and made the return home a hazardous journey for astronauts Swigert, James A. Lovell Jr., commander, and Fred W. Haise Jr., lunar module pilot.

(15 April 1970) —- Interior view of the Apollo 13 Lunar Module (LM) showing the “mail box,” a jury-rigged arrangement which the Apollo 13 astronauts built to use the Command Module (CM) lithium hydroxide canisters to purge carbon dioxide from the LM. Lithium hydroxide is used to scrub CO2 from the spacecraft’s atmosphere. Since there was a limited amount of lithium hydroxide in the LM, this arrangement was rigged up to utilize the canisters from the CM. The “mail box” was designed and tested on the ground at the Manned Spacecraft Center (MSC) before it was suggested to the problem-plagued Apollo 13 crew men. Because of the explosion of one of the oxygen tanks in the Service Module (SM), the three crew men had to use the LM as a “lifeboat”.

NASA successfully completed its first rendezvous mission with two Gemini spacecraft-Gemini VII and Gemini VI-in December 1965. This photograph, taken by Gemini VI crewmembers Walter Schirra and Thomas Stafford, shows Gemini VII in orbit 160 miles (257 km) above Earth. The main purpose of Gemini VI was the rendezvous with Gemini VII. The main purpose of Gemini VII, on the other hand, was studying the long-term effects of long-duration (up to 14 days) space flight on a two-man crew. The pair also carried out 20 experiments, including medical tests. Although the principal objectives of both missions differed, they were both carried out so that NASA could master the technical challenges of getting into and working in space.
