ExoMars parachute progress

Positive steps towards solving the problems discovered with the ExoMars mission parachutes have been taken in the last month to keep on track for the July-August 2020 launch window.

GOCE's second mission improving gravity map

(Phys.org)—ESA's GOCE gravity satellite has already delivered the most accurate gravity map of Earth, but its orbit is now being lowered in order to obtain even better results.

ExoMars parachute testing moves forward

The parachute system that will help deliver the Rosalind Franklin ExoMars rover to Mars has completed the first full-scale high altitude drop test with redesigned elements following two unsuccessful tests last year. Parachute ...

NASA's SAMPEX: A 3-year mission stretches to 20

(Phys.org)—NASA's very first small explorer, the Solar, Anomalous, and Magnetospheric Particle Explorer or SAMPEX, was launched July 3, 1992 to study the zoo of particles and cosmic rays surrounding Earth. Surviving much ...

Aerocapture is a 'free lunch' in space exploration

When spacecraft return to Earth, they don't need to shed all their velocity by firing retro-rockets. Instead, they use the atmosphere as a brake to slow down for a soft landing. Every planet in the solar system except Mercury ...

Image: Letting a satellite breathe

This air intake collector is designed to harvest sufficient air particles as it skims the top of the atmosphere to fuel an "air-breathing" electric thruster. The aim is to help satellites to overcome atmospheric drag to operate ...
