Last July, a team of robots explored a simulated martian landscape in Germany, guided by an astronaut aboard the International Space Station. This was the final session of the Surface Avatar experiment, a joint initiative between ESA and the German Aerospace Center (DLR) to investigate how astronauts can remotely control robotic teams.

This latest session took place at the DLR site in Oberpfaffenhofen and introduced new levels of autonomy, decision-making and realism, bringing Europe one step closer to seamless human-robot collaboration in space exploration.

Astronomers using the NASA/ESA/CSA James Webb Space Telescope have found strong evidence of a giant planet orbiting a star in the stellar system closest to our own Sun. At just 4 light-years away from Earth, the Alpha Centauri triple star system has long been a compelling target in the search for worlds beyond our solar system.

Louisville, CO – July 30, 2025 — Tendeg, a leader in deployable antenna systems for space, has completed construction of Innovation Drive, a 120,000 square foot facility purpose built to […]

A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet 3I/ATLAS, using the crisp vision of the NASA/ESA Hubble Space Telescope.

ESA's Planetary Defence Office responded promptly to the discovery of the comet, and has been tracking it since the beginning of July.

Now, Hubble's observations from space are allowing astronomers to more accurately estimate the size of the comet’s solid icy nucleus. The upper limit on the diameter of the nucleus is 5.6 km, but it could be as small as 320 m across, researchers report.

Though the Hubble images put tighter constraints on the nucleus size
