    La société américaine SpaceX a prévu d’envoyer lundi 14 août sur la Station spatiale internationale (ISS) une cargaison comprenant un super-ordinateur, afin de tester sa capacité à fonctionner dans l’espace pendant un an, dans des conditions extrêmes.

    Le décollage du lanceur #Falcon_9, transportant la capsule Dragon, est prévu à 12h31 (16h31 GMT) depuis la base de Cap Canaveral, en Floride et les conditions météorologiques sont favorables 70%. La capsule Dragon transporte 2,9 tonnes de marchandises, dont un supercalculateur conçu par la société informatique américaine Hewlett Packard Enterprise (HPE).

    Le but de cette mission est de voir si l’ordinateur peut fonctionner dans des conditions extrêmes dans l’espace pendant un an, la durée qu’il faudrait à des astronautes pour atteindre Mars.

    Plus les astronautes parcourent de longues distances, plus le délai de transmission des communications devient important. Il faudrait au moins 20 minutes pour que des messages envoyés depuis Mars atteignent la Terre et autant de temps dans l’autre sens.

    « Un tel délai de communication rendrait toute exploration sur le terrain compliquée et potentiellement dangereuse si les astronautes sont confrontés à des scénarios de mission cruciaux qu’ils ne seraient pas en mesure de résoudre par eux-mêmes », explique le vice-président de HPE, Alain Andreoli, dans un communiqué.

      SpaceX’s latest International Space Station Resupply mission has completed its latest step, with the Dragon capsule launched on Monday loaded with over 6,400 pounds of supplies successfully docked. Dragon met up with the ISS early Wednesday morning, roughly 36 hours after launching from Kennedy Space Center aboard a Falcon 9 rocket.

      The Dragon capsule, whose payload includes experiments including a novel software-hardened HP supercomputer designed for eventual use in a Mars mission, was captured by the ISS’s robotic Canadarm appendage after matching orbit with the ISS as planned. The capsule will now remain docked at the ISS for roughly a month, as astronauts work to unload its cargo of supplies and experiments.

      Dragon will also be reloaded with 3,000 pounds of cargo destined for a return to Earth, including experimental results being ferried back for examination by researchers and scientists on the ground. The capsule will de-orbit and then splash down in the Pacific Ocean for recovery if all goes as planned.

      This is the last new Dragon capsule SpaceX will use for ISS resupply, if all goes to the private space company’s plan: from here out, SpaceX hopes to use only refurbished, reused Dragons it has flown and recovered before to run CRS missions for NASA.

    • SpaceX lands another one of its Falcon 9 rockets on solid ground - The Verge

      SpaceX has landed yet another one of its Falcon 9 rockets after launching the vehicle into space this afternoon. The rocket took off from Cape Canaveral, Florida, at 12:31PM ET, bound for the International Space Station. Around eight minutes after takeoff, the majority of the vehicle landed back on solid ground off the Florida coast. It marks the 14th successful rocket landing for SpaceX, and the sixth time a Falcon 9 has successfully touched on solid ground post-launch.

      In fact, SpaceX has yet to lose a rocket during a ground landing. The company has lost a few vehicles during ocean landings, when the rockets attempted to touch down on autonomous drone ships at sea. But all six Falcon 9s that have landed on solid ground have touched down just fine at SpaceX’s Landing Zone 1 — a ground-based landing site at Cape Canaveral.
