For EVAs from the International Space Station, NASA employed a camp-out procedure to reduce the risk of decompression sickness. [34] This was first tested by the Expedition 12 crew. During a camp-out, astronauts sleep overnight in the airlock prior to an EVA, lowering the air pressure to 10.2 psi (70 kPa), compared to the normal station ...
The Apollo Lunar Module (LM / ˈ l ɛ m /), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only ...
The NASA X-57 Maxwell is an experimental aircraft being developed by NASA to demonstrate the technologies required to deliver a highly efficient all-electric aircraft. [142] The primary goal of the program is to develop and deliver all-electric technology solutions that can also achieve airworthiness certification with regulators.
Brownian excursion, a concept in the theory of stochastic processes; Critical excursion, or criticality accident, a topic in nuclear physics; Diaphragmatic excursion, the movement of the thoracic diaphragm during breathing; Geomagnetic excursion, a change in the Earth's magnetic field; Excursion (audio), the linear movement range of a speaker
Members of the NASA Astronaut Corps hold one of two ranks. Astronaut Candidate is the rank of those training to be NASA astronauts. Upon graduation from training, candidates are promoted to Astronaut and receive their Astronaut Pin. The pin is issued in two grades, silver and gold, with the silver pin awarded to candidates who have successfully ...
The Laschamp or Laschamps, also termed the Adams event, [1] was a geomagnetic excursion (a short reversal of the Earth's magnetic field). It occurred between 42,200 and 41,500 years ago, during the end of the Last Glacial Period.
A spacecraft prefix is a combination of letters, usually abbreviations, used in front of the name of a spacecraft, and its purpose is often analogous to more conventional ship prefixes.
A geomagnetic excursion, like a geomagnetic reversal, is a significant change in the Earth's magnetic field.Unlike reversals, an excursion is not a long-term re-orientation of the large-scale field, but rather represents a dramatic, typically a (geologically) short-lived change in field intensity, with a variation in pole orientation of up to 45° from the previous position.
