The Lunar Module (originally designated the Lunar Excursion Module, known by the acronym LEM) was designed after NASA chose to reach the Moon via Lunar Orbit Rendezvous (LOR) instead of the direct ascent or Earth Orbit Rendezvous (EOR) methods. Both direct ascent and EOR would have involved landing a much heavier, complete Apollo spacecraft on ...
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 ...
In early 1963, NASA selected Marshall for studies in an Apollo Logistics Support System (ALSS). Following reviews of all earlier efforts, this resulted in a 10-volume report. Included was the need for a pressurized vehicle in the 6,490–8,470 lb (2,940–3,840 kg) weight range, accommodating two men with their expendables and instruments for ...
Kelly was promoted to lead the design team for the Lunar Excursion Module (LEM). He was in charge of more than 7,000 employees in design and building the Lunar Module. Kelly's group came up with the idea of a two-stage spacecraft (ascent & descent stage), that would take two astronauts to the Moon's surface while a third astronaut would stay in ...
The excursion also marked the second-longest spacewalk conducted from the ISS. During the spacewalk, Fincke and Feustel hooked up a jumper to transfer 2.3 kg (5 lb ) of ammonia to the Port 6 Photovoltaic Thermal Control System (PVTCS), lubricated the Solar Alpha Rotary Joint (SARJ) and one of the "hands" on Dextre , and installed a stowage beam ...
The Mars Excursion Module (MEM) was a spacecraft proposed by NASA in the 1960s for use in a human mission to Mars, and this can refer to any number of studies by corporations and spaceflight centers for Mars landers. However, primarily a MEM referred to a combination of a Manned Mars lander, short-stay surface habitat, and Mars ascent stage.
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.
Space tourism is human space travel for recreational purposes. [1] There are several different types of space tourism, including orbital, suborbital and lunar space tourism. . Tourists are motivated by the possibility of viewing Earth from space, feeling weightlessness, experiencing extremely high speed and something unusual, and contributing to scie
