Astronauts took thousands of photographs of Earth, and the Earth Resources Experiment Package (EREP) viewed Earth with sensors that recorded data in the visible, infrared, and microwave spectral regions. The record for human time spent in orbit was extended beyond the 23 days set by the Soyuz 11 crew aboard Salyut 1 to 84 days by the Skylab 4 crew.
International Space Station. The International Space Station (ISS) is a large space station that was assembled and is maintained in low Earth orbit by a collaboration of five space agencies and their contractors: NASA (United States), Roscosmos (Russia), ESA (Europe), JAXA (Japan), and CSA (Canada). The ISS is the largest space station ever ...
The selection and training of astronauts are integrated processes to ensure the crew members are qualified for space missions. [6] The training is categorized into five objectives to train the astronauts on the general and specific aspects: basic training, advanced training, mission-specific training, onboard training, and proficiency maintenance training.

Apollo 15 (July 26 – August 7, 1971) was the ninth crewed mission in the Apollo program and the fourth Moon landing. It was the first J mission, with a longer stay on the Moon and a greater focus on science than earlier landings. Apollo 15 saw the first use of the Lunar Roving Vehicle. The mission began on July 26 and ended on August 7, with ...
Moonlight planners have proposed creating a new time zone for the Moon for this purpose, culminating in the introduction of the Coordinated Lunar Time standard in 2024. [83] Due to the lower gravity and relative motion, time passes more quickly on the Moon, making every 24-hour period elapse 56 microseconds early when measured from Earth. [84]
Apollo 11 was the second American mission where all the crew members had prior spaceflight experience, [54] the first being Apollo 10. [55] The next was STS-26 in 1988. [54] Deke Slayton gave Armstrong the option to replace Aldrin with Lovell, since some thought Aldrin was difficult to work with.
Mission Elapsed Time. Mission Elapsed Time (MET) is used by NASA during their space missions, most notably during their Space Shuttle missions. Due to the fact that timing is very consequential in a mission, all events after launch are scheduled on the Mission Elapsed Time. This avoids the constant rescheduling of events in case the launchtime ...
Skylab 4 (also SL-4 and SLM-3 [2]) was the third crewed Skylab mission and placed the third and final crew aboard the first American space station.. The mission began on November 16, 1973, with the launch of Gerald P. Carr, Edward Gibson, and William R. Pogue in an Apollo command and service module on a Saturn IB rocket from the Kennedy Space Center, Florida, [3] and lasted 84 days, one hour ...
