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.
Psychological and sociological effects of space flight are important to understanding how to successfully achieve the goals of long-duration expeditionary missions. Although robotic spacecraft have landed on Mars , plans have also been discussed for a human expedition , perhaps in the 2030s, [ 1 ] for a return mission.
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.
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.
At a speed of about 767 miles per hour, depending on temperature and humidity, a moving object will break the sound barrier. It was not until World War II, when aircraft started to reach the ...
In 2024, Jon Kelvey noted in an overview article that "the scientific community hasn't yet reached a consensus about whether the Kessler Syndrome has begun, or, if it has not begun, how bad it will be when it starts. There is consensus, however, that the basic concept is sound and that the space community needs to clean up its act." [39]
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.
