Q&A with Claire Leon, director of launch enterprise directorate at SMC

The satellite awaiting launch early Saturday from California aboard the final flight of the venerable Delta 2 rocket should allow scientists to more precisely track changes in our planet’s ice sheets, using six green laser beams to chart the height and slope of polar ice and glaciers, providing a key input into climate change research.

SpaceX decided to scrub a launch attempt on Saturday, May 3 and then postponed the launch with new launch date announced.

Two communications satellites blasted off Sunday aboard a SpaceX Falcon 9 rocket, kicking off more than a half-year of novel maneuvers in orbit using plasma drive engines to position the spacecraft 22,300 miles above Earth and link the Americas, Europe, Africa and the Middle East.
