For the first time, err, officially, NASA will set loose human sperm in outer space. The Micro-11 mission, which made its way to space aboard a SpaceX Falcon 9 rocket's Dragon resupply capsule, amounts to a bunch of containers of frozen human and bull sperm. Aboard the International Space Station (ISS), scientists will thaw the sperm, according to a NASA statement, and then study it to see how weightlessness affects its ability to move and prepare to fuse with an egg. "Previous experiments with sea urchin and bull sperm suggest that activating movement happens more quickly in microgravity," NASA officials wrote, "while the steps leading up to fusion happen more slowly, or not at all. Delays or problems at this stage could prevent fertilization from happening in space." [7 Facts About Sperm] NASA is sending up bull sperm along with human sperm, agency officials wrote, because the bull cells are more consistent in activity and appearance than human sperm. By studying it alongside the … [Read more...] about There’s a Lot of Sperm on the International Space Station Right Now

Boeing’s first crewed flight to the International Space Station may last a lot longer than originally planned — and the mission may have an extra crew member along for the ride, too. The company’s Starliner vehicle is supposed to take NASA astronauts to the ISS for the first time later this year on a two-week trip, but the space agency is considering extending the voyage to six months. Instead of sending just a two-person crew on the spacecraft, a third astronaut could be added as well. This would completely restructure the first crewed trip for Starliner, which was only meant to be a test flight. As part of NASA’s Commercial Crew Program, both Boeing and SpaceX have been developing private vehicles to transport astronauts to and from the ISS. But before the companies can start doing full missions to the station, NASA wants each spacecraft to do two test flights to the ISS first: one without people on board and then one with crew. The two-person test flights are … [Read more...] about NASA wants to extend Boeing’s first crewed flight to the International Space Station
Tech & Science A SpaceX Dragon cargo craft was launched from Cape Canaveral Air Force Station on Monday, bound for the International Space Station. The Dragon was filled with more than 5,800 pounds of research, cargo, supplies and equipment for astronauts aboard the ISS. Along with general supplies like food, the Dragon craft held some extra special cargo. Sperm and bone marrow were just two of the hundreds of items that arrived at ISS on Wednesday. The sperm was sent by NASA as part of a project called Micro-11 out of the Ames Research Center in California. The goal is to gain insight into how space flight and travel can affect human reproduction. Researchers aren’t sure sperm will be able to function normally enough in a zero-gravity environment to fertilize an egg in space. To test this, frozen samples of human and bull sperm were sent to the station and the plan is for the crew on board to thaw the samples before adding a chemical that can activate the … [Read more...] about Spacex Launched Sperm, a Space Trash Catcher and More to the International Space Station
