Airbus continues to collaborate with NASA to monitor climate change from Space

Airbus has been awarded a contract to design and build the GRACE-C twin spacecraft by NASA’s Jet Propulsion Laboratory JPL (Pasadena, California). This new mission of NASA and the German Space Agency at the German Aerospace Center (DLR) will strengthen the more than 20 year long partnership between the USA and Germany to ensure uninterrupted measurement of the Earth's gravity field, which started in 2002 with GRACE and continues with GRACE Follow-On, launched in 2018.

During its five year nominal mission lifetime, the GRACE-C Mission (Gravity Recovery And Climate Experiment-Continuity) will continue the series of measurements observing how Earth’s groundwater, oceans, ice sheets, and land shift, month-to-month, by measuring changes in the planet’s gravity field.

Alain Fauré, Head of Space Systems at Airbus, said: “It is amazing to think that, without looking down at Earth, two satellites more than 200 km away from each other, can tell us how quickly our ice sheets are melting. In environmental monitoring, continuity is key. The valuable data provided by the previous GRACE missions is testament to their success and it is great news that Airbus continues to be part of this international mission providing the tools to measure how our climate is evolving.”

GRACE-C consists of two identical satellites flying around 200 km apart at an orbit altitude of 500 km with an inclination of 89 degrees. Each satellite will measure approximately 3 x 2 x 1 metres and weigh around 600 kg. Launch is planned no earlier than late 2028 from the USA.
