  2. Reduced-gravity aircraft - Wikipedia

    en.wikipedia.org/wiki/Reduced-gravity_aircraft

    A300-Zero-G. NASA flew zero gravity flights on various aircraft for many years. In 1959 Project Mercury astronauts trained in a C-131 Samaritan aircraft dubbed the "vomit comet". [23] Twin KC-135 Stratotankers were used until December 2004 and later retired. One, a KC-135A registered N930NA (also known as NASA 930, formerly USAF serial no. 59 ...

    en.wikipedia.org/wiki/Convair_C-131_Samaritan

    In 1959, a C-131 was the first aircraft to be used as a reduced-gravity aircraft or 'vomit comet', for astronaut training as part of Project Mercury. [7] [8] [9] A Samaritan was the first aircraft used as a flying gunship testbed in mid-1963, in a program known as "Project Tailchaser". [10]

    en.wikipedia.org/wiki/Space_adaptation_syndrome

    In excellent physical condition, Garn did not become sick on the vomit comet before STS-51-D. [15] All three astronauts on Skylab 3 suffered from nausea, although the three on Skylab 2 had not; the illness affected their work during the first few days, worrying NASA doctors. [16] Experienced aviators and space travelers can suffer from space ...

  5. Low-g condition - Wikipedia

    en.wikipedia.org/wiki/Low-g_condition

    In fact, it can be enjoyable to have zero gravity in the cockpit. To produce 0g, the aircraft has to follow a ballistic flight path, which is essentially an upside down parabola. This is the only method to simulate zero gravity for humans on earth. In helicopters. In contrast, low-g conditions can be disastrous for helicopters.

  7. Neutral buoyancy simulation as a training aid - Wikipedia

    en.wikipedia.org/wiki/Neutral_buoyancy...

    The other major method used to simulate microgravity is flight in a reduced gravity aircraft (a so-called "vomit comet"), an aircraft which performs a number of parabolic climbs and descents to give its occupants the sensation of zero gravity. [9] Reduced-gravity aircraft training avoids neutral-buoyancy training's drag problem (trainees are ...

    Zero Gravity "G-FORCE ONE" aircraft People in the reduced-gravity aircraft. As of August 2022, the price of a flight for a single passenger starts at US$8,200. [12] The unique Weightless Weddings Experience is also included in the list of services [13] Noah and Erin Fulmor were the first couple to get married in weightlessness. [14]

    Zero-gravity training aircraft for simulating weightlessness (cf. Vomit Comet), including the MiG-15 UTI, Tupolev Tu-104 and later the IL-76 MDK with internal volume of 400 cubic metres (14,000 cu ft). Training aircraft are based at the Russian Air Force base at Chkalovskiy airfield. [citation needed] A Medical observation clinic and testing ...
