Next-generation NASA technologies tested in flight

Teams of NASA researchers put their next-generation technologies to the microgravity test in a series of parabolic flights that aim to advance innovations supporting the agency's space exploration goals.

Would astronauts' kidneys survive a roundtrip to Mars?

The structure and function of the kidneys is altered by space flight, with galactic radiation causing permanent damage that would jeopardize any mission to Mars, according to a new study led by researchers from UCL.

Human bodies mostly recover from space, tourist mission shows

How bad for your health is space travel? Answering this question will be crucial not just for astronauts aiming to go to Mars, but for a booming space tourism industry planning to blast anyone who can afford it into orbit.

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.
