Q&A with Marc Eisenberg, Orbcomm’s chief executive

SpaceX’s Falcon 9 rocket rolled out to its launch pad at Vandenberg Air Force Base, California, on Monday, one day before its scheduled liftoff carrying seven satellites into orbit on commercial communications and climate research missions.

Look back on the May 30 launch of a Russian Proton rocket from the Baikonur Cosmodrome in Kazakhstan with this gallery of photos showing the 19-story launcher climbing into the sky with the Yamal 601 communications satellite.

Launch preparations for the SES 10 communications satellite, the first spacecraft to ride a reused Falcon 9 booster to space, are on track for a late March blastoff from Florida, officials said.
