Après des années de retards, de changements de partenaires et de bouleversements géopolitiques, la première mission européenne de rover martien dispose désormais d’un lanceur confirmé : le Falcon Heavy de SpaceX, avec un décollage visé fin 2028.

Researchers at the University of Southern California report a memristor that operated reliably at 700 degrees Celsius, a result that could reshape electronics for Venus missions and other extreme environments.

Jeff VanderMeer’s new story in MIT Technology Review imagines stranded explorers traversing a hostile planet linked by immense paths between 13 heated domes. The result is a tense meditation on survival, contact, and the

NASA has published the first official moon-flyby images from Artemis II, including a rare in-space solar eclipse and views of terrain on the lunar far side as the crew returns to Earth.

NASA’s Artemis 2 crew completed a lunar flyby on April 6, 2026, circling behind the moon, witnessing a total solar eclipse from beyond it, and traveling farther from Earth than any humans before them.

Le spécialiste de mission d’Artemis II, Jeremy Hansen, s’apprête à devenir le premier Canadien à faire le tour de la Lune, couronnant une longue attente qui a inclus des années de travail technique, de politique et de formation d’astronautes.

Alors que NASA finalise les préparatifs pour Artemis II — la première mission habitée au-delà de l'orbite terrestre basse depuis Apollo — l'agence converge avec Hollywood dans la sortie de 'Project Hail Mary', que des scientifiques de NASA ont aidé à façonner et que les équipages de l'ISS ont regardée en orbite.

Il y a un siècle, Robert Goddard a lancé la première fusée alimentée par carburant liquide du monde dans un champ du Massachusetts, volant pendant seulement 2,5 secondes dans un moment qui a changé la trajectoire de la civilisation.

Scientists analyzing dust samples returned from asteroid Ryugu by Japan's Hayabusa-2 mission have uncovered a 4.6-billion-year magnetic record that reveals conditions in the earliest days of the solar system.

NASA's Juno spacecraft discovers that auroras on Jupiter's moon Ganymede splinter into bright patches mirroring Earth's northern lights.

Hollywood has painted a romanticized picture of life on the Red Planet, from Matt Damon growing potatoes to Arnold Schwarzenegger surviving the Martian surface. But experts say the real challenges of off-world living are far more daunting and far less cinematic than anything science fiction has prepared us for.

Scientists have created the first three-dimensional map of Uranus's upper atmosphere using the James Webb Space Telescope, revealing how the planet's bizarre tilted magnetic field creates complex auroral patterns and drives atmospheric cooling. The 15-hour observation session captured faint molecular emissions up to 5,000 kilometers above the clouds.

NASA will attempt to fuel its Artemis 2 Space Launch System rocket for the second time on February 19, after a hydrogen leak during the first wet dress rehearsal forced the agency to wave off a February launch window. If the test succeeds, a crewed lunar mission could launch as early as March.

A hydrogen fuel leak during the Artemis II wet dress rehearsal has pushed the crewed Moon mission from February to March 2026, as technicians replace seals on the mobile launcher.

A new strategic analysis outlines three pathways for deploying fission reactors on the Moon and Mars, arguing that nuclear power is the only viable option for sustained human presence beyond Earth.

Germany committed 78 million euros to a new space exploration control center, reinforcing its role in lunar and deep-space human missions.
