SpaceX's plans to colonize Mars differ considerably from NASA's Journey to Mars ambitions. But direct comparison is difficult. SpaceX is able to wipe the slate clean and start fresh with a bold new approach to humans in space. NASA has no such luxury, and must use existing pieces and people to make their goals a reality.
After much anticipation, Elon Musk revealed his plans to colonize Mars. Here are the details, some questions yet to be answered, and a few thoughts on how this could change the way we think about human spaceflight.
Four days of cargo craft mania came to a close at the International Space Station this morning, as astronauts Kate Rubins and Jeff Williams snagged an approaching SpaceX Dragon vehicle and berthed it to the laboratory's Harmony module.
Tomorrow morning, Tim Kopra, Tim Peake and Yuri Malenchenko are coming home from the International Space Station. But if you live in the United States or Europe, you're going to have to get up pretty early—or stay up late—to see it happen.
This afternoon, NASA started a fire aboard a trash-filled cargo spacecraft, but it was all in the name of science. Engineers at the agency's Glenn Research Center are studying how large-scale fires spread in space.
BEAM, the International Space Station's new expandable habitat module, is open for business. NASA astronaut Jeff Williams and cosmonaut Oleg Skripochka entered the module at 4:47 a.m. EDT (9:47 UTC) this morning.
BEAM is expanded and pressurized! The International Space Station's newest module, which will serve as a technology demonstrator for in-space expandable habitats, was fully filled with air this afternoon.
NASA will try again tomorrow to expand BEAM, the Bigelow Expandable Activity Module. During a press teleconference this afternoon, officials said they were confident the module was going to expand—it's just a question of when.
