Japanese astronaut joins the crew for SpaceX Dragon mission to space station

The first non-American to be added to the crew for a SpaceX Dragon flight to the International Space Station is Japanese astronaut Soichi Noguchi. Noguchi first visited the space station in 2005 during the first space shuttle flight following the 2003 Columbia shuttle tragedy, and rode a Russian Soyuz spacecraft for a six-month orbital stay on the station in 2009-2010. For his next mission, Noguchi will be teaming up with NASA's Michael Hopkins and Victor Glover Jr. — plus Shannon Walker, wh...

Univ. of Washington studies antimalarial drug’s use to head off COVID-19, with Gates Foundation’s aid

University of Washington researchers are among the leaders of a newly announced clinical trial investigating whether hydroxychloroquine, a drug that's commonly used to counter malaria and autoimmune disease, can prevent COVID-19. The multi-site trial, managed by UW in collaboration with New York University's Grossman School of Medicine, aims to determine definitively whether taking the drug can prevent transmission in people exposed to the virus. "We currently don’t know if hydroxychloro...

Whales face more fatal ship collisions as waters warm

Climate change is imperiling the world's largest animals by increasing the likelihood of fatal collisions between whales and big ships that ply the same waters. Warming ocean temperatures are causing some species of whales in pursuit of food to stray more frequently into shipping lanes, scientists say. The phenomenon already has increased ship strikes involving rare North Atlantic right whales on the East Coast and giant blue whales on the West Coast, researchers say.

SpaceX wins NASA contract to send cargo to lunar Gateway with new Dragon XL craft

NASA has tapped a type of SpaceX cargo craft that hasn't yet been built to deliver supplies to a moon-orbiting outpost that hasn't yet been launched. SpaceX's robotic Dragon XL, a cylindrical, supersized version of its workhorse Dragon spacecraft, will handle shipments to the Gateway space platform as the first commercial provider to receive a Gateway Logistics Services contract from NASA. The contract is similar to NASA's existing Commercial Resupply Services contracts with Spac...

Xplore’s Xcraft space probe lands in Xtronaut 2.0 board game — and STEM students are the winners

Seattle-based Xplore isn't due to launch its first Xcraft space probe until late 2021, but it's already landed in an educational board game. Xtronaut 2.0, a multiplayer game devised by planetary scientist Dante Lauretta and Xtronaut Enterprises CEO Michael Lyon, will feature Xcraft as one of the deck's playing cards. Players can combine the cards to create their own game-board missions to deep space. The arrangement is part of a sponsorship deal for Xtronaut 2.0's Kickstarter cro...

Calling all kids: Send Blue Origin a space postcard while you’re stuck at home

Are you looking for educational activities to occupy the kids while you're cooped up due to the coronavirus outbreak? One option is to make space postcards for the Club for the Future, an educational campaign created by Amazon CEO Jeff Bezos' Blue Origin space venture. Last year, Blue Origin collected thousands of student-decorated cards, and sent them to space and back on its New Shepard suborbital craft. After the flight, the cards were stamped "Flown in Space" (in some cases, by Bezos...
