SpaceX shows off Dragon capsules for Polaris Dawn, Crew-9 astronaut missions (photos)
These two Dragons are getting ready to spread their wings. SpaceX just gave us a look at the Crew Dragon capsules that will fly on the Polaris Dawn and Crew-9 astronaut missions, which are set to launch on Aug. 26 and Sept. 24, respectively. “Double Dragons readying for flight ahead of the Polaris Dawn and Crew-9 human spaceflight missions,” the company wrote in an X post on Wednesday (Aug. 21) that featured two photos of the capsules, side by side in a processing facility on Florida’s Space Coast. Polaris Dawn…

“What happens when you throw a star at a black hole?” It’s not a question we can physically answer here on Earth. Thankfully, actual black holes and stars can’t be smashed together in the lab! However, scientists can use advanced supercomputer modeling to simulate a black hole ripping apart and devouring a star in a so-called “tidal disruption event” or “TDE.” Doing just that, a team of researchers led by Danel Price from Monash University has discovered that the answer to our opening question is “things get messy.” “Black holes…

2 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) In-space propulsion systems utilizing cryogenic liquids as propellants are necessary to achieve NASA’s exploration missions to the Moon, and later to Mars. In current state of the art (SOA) human scale, in-space propulsion vehicles, cryogenic liquids can be stored for several hours. For the planned HLS mission architecture to close, cryogenic liquids must be stored on-orbit on the order of several months. NASA’s 2025 HuLC Competition asks student teams to develop innovative, systems-level solutions to understand, mitigate potential problems,…

In our solar system, scattered across one of Earth’s verdant mountains, six eggshell-white telescopes gaze into the deep universe. As one cohesive hive, the domed structures collect cosmic light to guide modern astronomers exploring space — and it is thanks to this hive that we now have a brilliant new perspective on the light that guided astronomers of the past: the North Star. Our visual knowledge of the current North Star (because of Earth’s axial wobble, the title passes to different stars over the eons) runs deep. Artists, old and…

2024-08-20T20:08:06.397Z Polaris Dawn crew 1 week from launch (Image credit: Polaris Program / John Kraus) The four private astronauts of SpaceX’s Polaris Dawn mission are a week away from launch after two years of training for a mission that, they hope, will include the world’s first private spacewalk. American billionaire Jared Isaacman, who previously backed his private Inspiration4 spaceflight with SpaceX, will command the Polaris Dawn mission, the first of three new spaceflights he’s purchased from SpaceX. Isaacman, pilot Scott “Kidd” Poteet, and mission specialists Sarah Gillis and Anna Menon,…
