Photos: Falcon takes flight

Keith Gendreau, an astrophysicist at NASA’s Goddard Space Flight Center, recently spoke with Spaceflight Now about a new experiment on the International Space Station to demonstrate X-ray communications in space for the first time.

Physicists are gearing up to send a re-engineered science instrument originally designed for lofty balloon flights high in Earth’s atmosphere to the International Space Station next week to broaden their knowledge of cosmic rays, subatomic particles traveling on intergalactic routes that could hold the key to unlocking mysteries about supernovas, black holes, pulsars and dark matter.

SpaceX’s first mission since a rocket explosion on a Florida launch pad is now scheduled for early January, when a Falcon 9 booster is set to begin a 70-satellite deployment for Iridium’s next-generation voice and data relay network, the company announced Wednesday.
