NASA just declared its MAVEN Mars orbiter dead after a dozen productive years circling the Red Planet. Here's the fate that awaits the probe.

Le Français Arnaud Prost rejoindra en 2027 la mission inaugurale de Haven-1, la future station spatiale commerciale développée par Vast. L'entreprise américaine entend réduire fortement les coûts des infrastructures orbitales et préparer la relève de l'ISS avant sa désorbitation prévue vers 2030.

Scientists failed to find radio signals emanating from the interstellar comet 3I/ATLAS, further bolstering its status as a natural object, not one made by aliens.

Après six mois sans contact, la Nasa a officiellement mis fin à la mission Maven. En plus de dix ans en orbite autour de Mars, la sonde a profondément renouvelé les connaissances sur l'atmosphère, le climat passé et l'habitabilité de la planète Rouge.

NASA has confirmed its MAVEN spacecraft is officially dead after losing contact with the probe in December. An anomaly in the probe's rotation speed led to an unexpected loss of power, though the exact cause remains unknown.

After its rocket explosion, Blue Origin wants to complete repairs and put another New Glenn on the launchpad before the end of 2026, according to CEO Dave Limp. That's very ambitious.
