Pentagon chief sharpens warnings to defense contractors over delivery, pay and buybacks

When satellites eventually fall back down to Earth, they mostly burn up because of the friction caused by the atmosphere. Scientific data about this atmospheric reentry process is urgently needed to design future satellites for a quick, safe and sustainable demise at the end of their mission – reducing risks on the ground and in space.

The European Space Agency (ESA) successfully manoeuvred its remaining two Cluster satellites to ensure they can both be observed from a plane as they reenter the atmosphere on 31 August and 1 September 2026.

Satellite navigation is essential to everyday life, from tracking your morning jog to landing air ambulances. But as reliance on satellite navigation grows, so do the risks associated with its interruption, natural or intentional. To strengthen European resilience in navigation, the European Space Agency (ESA) takes part annually in Jammertest.

Organised on the remote island of Andøya, Norway, Jammertest is the world’s largest open air testing campaign for jamming and spoofing resilience. In September 2025, ESA engineers attended Jammertest with ESA’s mobile navigation lab to test how different systems respond to interference. After this, the data are analysed

Amazon has purchased an additional 10 Falcon 9 launches from SpaceX as part of its efforts to accelerate deployment of its broadband satellite constellation.

Transcelestial, a startup developing optical communications technologies, has signed an agreement with Gilmour Space Technologies to incorporate its technology on Gilmour Space spacecraft.
