Les États-Unis entrent dans un nouveau « shutdown », séquence lors de laquelle des centaines de milliers de fonctionnaires se retrouvent à l'arrêt. Dans ce contexte, l'agence spatiale américaine (Nasa) est aussi touchée.

Un astéroïde est passé à moins de 300 km de la surface de la Terre le 1er octobre. Un événement rare et d'autant plus inquiétant qu'il n'a pu être repéré que quelques heures avant son arrivée.

Ils sont 4 hommes et 6 femmes à avoir été sélectionnés par la Nasa pour représenter la prochaine génération d'astronautes. Une annonce qui se produit en pleine incertitude dans le milieu du spatial aux États-Unis. Alors, que vont faire ces futurs voyageurs spatiaux ?

Tout est rentré dans l'ordre : le vaisseau cargo Cygnus XL, affrété par Northrop Grumman et lancé par une fusée Falcon 9 de SpaceX, a fini par rejoindre la Station spatiale internationale (ISS). Deux jours avant, le véhicule subissait un dysfonctionnement au niveau de sa propulsion.

Le ravitaillement de la Station spatiale internationale avec le cargo de Northrop Grumman ne se déroule pas comme prévu. Alors qu'il devait rejoindre l'ISS le 17 septembre, une autre date doit être déterminée.

Une capsule Dragon de SpaceX a procédé à une manœuvre pour pousser la station spatiale internationale, et ainsi la maintenir sur son orbite. Une opération délicate qui se déroulera de nouveau dans les mois à venir.

Take a look at what being called "a stunning phenomenon," captured in a photo taken from the International Space Station as it passed above a thunderstorm over Mexico and the American Southwest. So what was it? "A rare form of Transient Luminous Event (TLE) called a gigantic jet," according to a new blog post at Notebookcheck.net: A gigantic jet happens above thunderstorms, firing powerful bursts of electrical charge from the top of the thunderstorm (about 20 km [12.4 miles] above the ground) into the upper atmosphere (about 100 km [62.1 miles] above the ground). The upper part of gigantic jets produces red emissions identical to sprites [large-scale electric discharges above thunderclouds]. But while gigantic jets burst directly from the top of thunderstorms, sprites form independently, much higher in the atmosphere, appearing around 50 miles (80 km) above the Earth's surface. "If ordinary lightning seems pretty ordinary, upper-atmosphere lightning is something else — an entire zoo of various upper-atmosphere electrical discharges," writes the Severe Weather Europe site. And NASA made a request in a new blog post this week to any aspiring citizen scientists. "Have you captured an image of a jet, sprite, or other type of TLE? Submit your photos to Spritacular.org to help scientists study these fascinating night sky phenomena!"

After five months on the International Space Station, four astronauts splashed down in the Pacific Ocean in a SpaceX Crew Dragon capsule named Endurance, reports Space.com. It was NASA's 10th commercial crew rotation mission: The flight launched atop a SpaceX Falcon 9 rocket on March 14 and arrived at the orbiting lab two days later. Crew-10's four astronauts soon set to conducting science work, which consumed much of their time over the ensuing months... The wheels for Crew-10's departure began turning last Saturday (Aug. 2), when SpaceX's four-person Crew-11 mission arrived at the International Space Station. The Crew-10 astronauts spent a few days advising their replacements, then set their minds to gearing up for the return to Earth — and reflecting on their orbital experience. "We got to accomplish a lot of really amazing operational things," Ayers said during a farewell ceremony on Tuesday (Aug. 5). "We got to see some amazing views, and we have had some really big belly laughs and a wonderful time together," she added. "I think that [we're] leaving with a heart full of gratitude, and [we're] excited to see where the International Space Station goes after we get home." The hatches between Endurance and the ISS closed on Friday (Aug. 8) at 4:20 p.m. EDT (2020 GMT), and the capsule undocked about two hours later, at 6:15 p.m. EDT (2205 GMT). Endurance then began maneuvering its way back to Earth, setting up its splashdown today. It was the first Pacific Ocean return for a SpaceX CCP mission; all previous such flights have come down off the Florida coast. SpaceX recently shifted to West Coast reentries for all of its Dragon missions, both crewed and uncrewed, to minimize the chance that falling space debris could damage property or injure people. "During their mission, crew members traveled nearly 62,795,205 million miles," NASA announced, "and completed 2,368 orbits around Earth..." Along the way, Crew-10 contributed hundreds of hours to scientific research, maintenance activities, and technology demonstrations. McClain, Ayers, and Onishi completed investigations on plant and microalgae growth, examined how space radiation affects DNA sequences in plants, observed how microgravity changes human eye structure and cells in the body, and more. The research conducted aboard the orbiting laboratory advances scientific knowledge and demonstrates new technologies that enable us to prepare for human exploration of the Moon and Mars. McClain and Ayers also completed a spacewalk on May 1, relocating a communications antenna, beginning the installation of a mounting bracket for a future International Space Station Roll-Out Solar Array, and other tasks.
