  2. Sound barrier - Wikipedia

    en.wikipedia.org/wiki/Sound_barrier

    The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible.

  3. Space psychology - Wikipedia

    en.wikipedia.org/wiki/Space_psychology

    Space psychology refers to applying psychology to advise human spaceflight.This includes applying industrial and organizational psychology to team selection, individual and team mental preparation, team training, and ongoing psychological support, [1] and applying human factors and ergonomics to the construction of spacecraft to ensure sufficient habitability.

  4. Space Shuttle program - Wikipedia

    en.wikipedia.org/wiki/Space_Shuttle_program

    The Space Shuttle program was the fourth human spaceflight program carried out by the U.S. National Aeronautics and Space Administration (NASA), which accomplished routine transportation for Earth-to-orbit crew and cargo from 1981 to 2011.

  5. Space Shuttle - Wikipedia

    en.wikipedia.org/wiki/Space_Shuttle

    The Space Shuttle external tank (ET) carried the propellant for the Space Shuttle Main Engines, and connected the orbiter vehicle with the solid rocket boosters. The ET was 47 m (153.8 ft) tall and 8.4 m (27.6 ft) in diameter, and contained separate tanks for liquid oxygen and liquid hydrogen.

  6. Sonic boom - Wikipedia

    en.wikipedia.org/wiki/Sonic_boom

    The sound of a sonic boom depends largely on the distance between the observer and the aircraft shape producing the sonic boom. A sonic boom is usually heard as a deep double "boom" as the aircraft is usually some distance away. The sound is much like that of mortar bombs, commonly used in firework displays. It is a common misconception that ...

  7. List of Space Shuttle missions - Wikipedia

    en.wikipedia.org/wiki/List_of_Space_Shuttle_missions

    The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated by NASA (the National Aeronautics and Space Administration). Its official program name was Space Transportation System (STS), taken from a 1969 plan for a system of reusable spacecraft of which it was the only item funded for development. [ 1 ]

  8. Hypersonic speed - Wikipedia

    en.wikipedia.org/wiki/Hypersonic_speed

    Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially because of the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.

  9. Sound suppression system - Wikipedia

    en.wikipedia.org/wiki/Sound_Suppression_System

    Sites for launching large rockets are often equipped with a sound suppression system to absorb or deflect acoustic energy generated during a rocket launch. As engine exhaust gasses exceed the speed of sound , they collide with the ambient air and shockwaves are created, with noise levels approaching 200 db.
