SpaceX launches upgraded solar arrays and innovative satellite on NASA cargo mission.

SpaceX is set to launch its 28th cargo mission to the International Space Station (ISS) for NASA today, carrying a few thousand pounds of science investigation supplies and provisions for the station's crew. The cargo Dragon will spend just over 40 hours on an intercept course with the ISS. The Falcon 9's first stage will perform a boost-back burn and land on SpaceX's autonomous droneship A Shortfall of Gravitas. The cargo Dragon is designed as a reusable vehicle, and will return scientific samples from over 34 investigations aboard the ISS at the end of its stay at the station.
