'Tube map' around planets and moons made possible by knot theory

Just as sat-nav did away with the need to argue over the best route home, scientists from the University of Surrey have developed a new method to find the optimal routes for future space missions without the need to waste ...

Space exploration: A luxury or a necessity?

"Oh, come on Daniel, space travel is so expensive, and pointless!" These were the words of my friend Max, during a Christmas party where I was discussing my thesis project: studying places on Earth where the living conditions ...

NASA technology helps guard against lunar dust

Defeating dust may be a small concern for most people on Earth, but for astronauts and spacecraft destined for the moon or Mars, it is a significant hazard that must be mitigated. That's why researchers at NASA's Kennedy ...

Through astronaut eyes, virtual reality propels gateway forward

NASA astronauts are using virtual reality to explore Gateway. When they slip on their headsets, they're not just seeing the station—they're in it, meticulously surveying every detail and offering crucial insights on design ...

Spaceflight

Spaceflight is the use of space technology to achieve the flight of spacecraft into and through outer space.

Spaceflight is used in space exploration, and also in commercial activities like space tourism and satellite telecommunications. Additional non-commercial uses of spaceflight include space observatories, reconnaissance satellites and other earth observation satellites.

A spaceflight typically begins with a rocket launch, which provides the initial thrust to overcome the force of gravity and propels the spacecraft from the surface of the Earth. Once in space, the motion of a spacecraft -- both when unpropelled and when under propulsion -- is covered by the area of study called astrodynamics. Some spacecraft remain in space indefinitely, some disintegrate during atmospheric reentry, and others reach a planetary or lunar surface for landing or impact.
