Lt. Gen. DeAnna Burt, deputy chief of space operations, is retiring after 33 years of service.

SALT LAKE CITY – It’s easy to talk about satellite autonomy but significant work remains to determine exactly which tasks should be handled by machines, according to speakers at the 2025 Small Satellite Conference.

The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our solar system because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water on its surface is theoretically possible. But according to a new study using data from the NASA/ESA/CSA James Webb Space Telescope, it does not have an Earth-like atmosphere.

Insurers are returning to the space industry after retreating in the wake of harrowing losses just a few years ago.

An Ariane 6 successfully launched a European weather satellite with an Earth science hosted payload Aug.

Europe’s first MetOp Second Generation, MetOp-SG-A1, weather satellite – which hosts the Copernicus Sentinel-5 mission –  has launched aboard an Ariane 6 rocket from Europe’s Spaceport in French Guiana. The rocket lifted off on 13 August at 02:37 CEST (12 August 21:37 Kourou time).

MetOp-SG-A1 is the first in a series of three successive pairs of satellites. The mission as a whole not only ensures the continued delivery of global observations from polar orbit for weather forecasting and climate analysis for more than 20 years, but also offers enhanced accuracy and resolution compared to the original MetOp mission –
