‘Kidney on a chip’ gets another ride to space

SpaceX launched a Dragon cargo capsule to the International Space Station today with more than 7,300 pounds of supplies and science, including an experiment from the University of Washington that takes advantage of zero gravity to study how our kidneys work.

The resupply mission began at 1:29 p.m. ET (10:29 a.m. PT) with liftoff for SpaceX’s Falcon 9 rocket from NASA’s Kennedy Space Center in Florida. Minutes after launch, the Falcon’s first-stage booster flew itself back to an at-sea touchdown in the Atlantic Ocean, while the Dragon continued its rise to orbit.

Rendezvous with the space station took place on June 5.

SpaceX’s 22nd cargo resupply mission is carrying a wide range of science experiments. One will use glow-in-the dark bobtail squid to study the impact of spaceflight on interactions between microbes and their hosts. Another will study how tardigrades are able to weather the rigors of space. And then there’s UW’s “kidney on a chip.”
