Halted rocket test could stall NASA moon shot, redo possible

NASA is considering a second firing of its moon rocket engines after a critical test came up short over the weekend, a move that could bump the first flight in the Artemis lunar-landing program into next year.

Window opens for Virgin Galactic test flight from spaceport

The window opened Friday for Virgin Galactic's first rocket-powered test flight from Spaceport America in southern New Mexico as the company prepares for commercial flights next year, but the exact timing of the launch will ...

Scientists solve big limitation of stratospheric balloon payloads

Nearly all photons emitted after the Big Bang are now visible only at far-infrared wavelengths. This includes light from the cold universe of gas and dust from which stars and planets form, as well as faint signals from distant ...

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.
