      Que se passerait-il si l’on voyageait quasiment à la vitesse de la lumière ?

    L'agence spatiale américaine a publié une vidéo amusante pour décrire les effets d'un voyage spatial quasiment à la vitesse de la lumière. À cette vitesse, la perception du temps et de l'espace serait bien différente. [Lire la suite]

      Blast off: Disney drops first trailer for The Right Stuff dramatic series

      Jennifer Ouellette • news.movim.eu / ArsTechnica • 20 August, 2020 • 1 minute

    In October, Disney+ will debut its new series, The Right Stuff, based on the 1979 book by Tom Wolfe.

    A team of elite military test pilots finds itself tapped to be astronauts for Project Mercury , the first human spaceflight program in the United States, in The Right Stuff , a new eight-episode dramatic series debuting in October on Disney+. Like Philip Kaufman's Oscar-winning 1983 film of the same name, the series is based on the bestselling 1979 book by Tom Wolfe.

    Wolfe became interested in the US space program while on assignment by Rolling Stone to cover the launch of Apollo 17, NASA's last Moon mission. He spent the next seven years writing The Right Stuff , intent on capturing the drive and ethos of those early astronauts. (In a foreword to the 1983 edition, he pondered "What makes a man willing to sit up on top of an enormous Roman candle... and wait for someone to light the fuse.")  Wolfe spent a great deal of time consulting with General Chuck Yeager, who was shut out of the astronaut program and ended up as a contrasting character to the college-degreed Project Mercury team featured in the book. The Right Stuff won widespread critical praise, as well as the National Book Award for Nonfiction.

    When United Artists decided to finance a film adaptation , the studio hired William Goldman ( The Princess Bride ) to adapt the screenplay, but his vision was very different from that of director Philip Kaufman, and Goldman quit the project. Kaufman wrote his own draft script in eight weeks, making Yeager more of a central figure; Goldman's script ignored Yeager entirely. Goldman later wrote that "Phil [Kaufman]'s heart was with Yeager. And not only that, he felt the astronauts, rather than being heroic, were really minor leaguers, mechanical men of no particular quality, not great pilots at all, simply the product of hype."

    The US Attorney's Office for the District of Columbia has opened a criminal investigation of a former top NASA official, the Wall Street Journal reported Friday .

    The grand jury investigation concerns communications between Doug Loverro, then the chief of human spaceflight for NASA, and Jim Chilton, senior vice president of Boeing's space and launch division. These discussions occurred early this year, during a blackout period when NASA was taking bids to construct a Human Landing System for the Artemis Moon Program. It is not permissible to interfere with a competition for government contracts.

    "Mr. Loverro, who wasn’t part of NASA’s official contracting staff, informed Mr.Chilton that the Chicago aerospace giant was about to be eliminated from the competition based on cost and technical evaluations," the report states, citing unidentified sources. "Within days, Boeing submitted a revised proposal."

      Dragonship Endeavour is flying free, on its way back to Earth

    On Saturday evening the Crew Dragon spacecraft carrying NASA astronauts Doug Hurley and Bob Behnken, named Dragonship Endeavour , undocked from the International Space Station to begin its journey home.

    The undocking came after NASA and SpaceX determined the spacecraft would find calm seas and light winds off the coast from the Florida Panhandle, in the Gulf of Mexico, on Sunday. This will be the first water landing for a U.S. spacecraft since 1975, when an Apollo capsule splashed down after the Apollo-Soyuz Test Project in the Pacific Ocean. Landing is slated for 2:48pm ET (18:40 UTC). A final call on weather will be made on Sunday.

    After moving away from the "Keep Out Sphere" surrounding the space station, Endeavour will put distance between itself and the orbiting laboratory before performing more engine burns. This will set the spacecraft up for a de-orbit burn on Sunday, about 50 minutes before splashdown. Asked what he and Behnken would spend most of their final night in space doing, Hurley quipped during a news conference with reporters this week, "Sleeping."
