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.
Sub-orbital space flights, being at a much lower speed, do not generate anywhere near as much [further explanation needed] heat upon re-entry. Even if the orbiting objects are expendable, most [ quantify ] space authorities [ example needed ] are pushing toward controlled re-entries to minimize hazard to lives and property on the planet.
First living organisms to fly in space and safely return. USSR Soviet space dogs [7] 5 October 1954: The composite image taken from specially modified cameras on-board an Aerobee sounding rocket produces the first color picture of Earth, the first detailed view of a tropical storm and the first complete (albeit distorted) view of the planet.
The Hubble Space Telescope's Wide Field Camera 3 has the potential to provide a precision of 20 to 40 microarcseconds, enabling reliable distance measurements up to 5,000 parsecs (16,000 ly) for small numbers of stars. [5] [6] The Gaia space mission provided similarly accurate distances to most stars brighter than 15th magnitude. [7]
Notable test flights of spaceflight systems may be listed even if they were not planned to reach space. Some lists are further divided into orbital launches (sending a payload into orbit, whether successful or not) and suborbital flights (e.g. ballistic missiles, sounding rockets, experimental spacecraft).
