Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
A spacecraft is a vehicle that is designed to fly and operate in outer space. [1] Spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and cargo.
The mission touched down safely, and the crew was reflown with the same mission plan on STS-94. Collision in space 25 June 1997: Mir: At Mir, during a re-docking test with the Progress M-34 cargo freighter, the Progress freighter collided with the Spektr module and solar arrays of the Mir space station. This damaged the solar arrays and the ...
If the near-light-speed space craft is interacting with matter that is moving slowly in the planetary reference frame, this will cause drag which will bleed off a portion of the engine's acceleration. A second big issue facing ships using constant acceleration for interstellar travel is colliding with matter and radiation while en route.
Aldrin held that reusable spacecraft were the key in making space travel affordable, stating that the use of "passenger space travel is a huge potential market big enough to justify the creation of reusable launch vehicles". [76] Space tourism is a next step in the use of reusable vehicles in the commercialization of space.
Odin, named for the father of Thor in Norse mythology, will be one of the first spacecraft developed by a private sector company to travel to deep space, or beyond the moon. The spacecraft is set ...
spacecraft Habitation Return spacecraft Brief mission summary 1 Yuri Gagarin: 12 April 1961 Vostok 1: First crewed spaceflight. Reached Low Earth Orbit (LEO), flew around the Earth one time. 2 Alan Shepard (1) 5 May 1961 Mercury-Redstone 3 : First American crewed spaceflight. Did not reach Earth orbit, maximum altitude: 187 km (116 miles). [1 ...
A Bussard ramjet, one of many possible methods that could serve to propel spacecraft. Interstellar travel is the hypothetical travel of spacecraft between star systems.Due to the vast distances between the Solar System and nearby stars, interstellar travel is not practicable with current propulsion technologies.
