Q&A with Keith Gendreau, principal investigator of the first X-ray space communications experiment (members only)

Managers aborted liftoff of a commercial Antares cargo launcher Saturday when an aircraft strayed into restricted airspace near the rocket’s planned flight path east from Virginia’s Eastern Shore.

Look back on last week’s blastoff of a SpaceX Falcon 9 rocket from Cape Canaveral with NASA’s Transiting Exoplanet Survey Satellite.

SpaceX launched more than 2,500 of its satellites so far this year. It executed liftoff of its Falcon 9 rocket from pad 4E at Vandenberg Space Force Base on Friday at 1:41 p.m. PDT (4:41 p.m. EDT / 2041 UTC).
