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

A Falcon 9 rocket took off from Cape Canaveral Wednesday with another batch of 60 Starlink internet satellites, achieving success on SpaceX’s 100th mission to launch from Florida’s Space Coast and clearing the way for liftoff of a NASA crew mission to the International Space Station later this month.

Hazardous anvil clouds approaching from a nearby thunderstorm forced SpaceX to abort the takeoff of a Falcon 9 launcher Monday, delaying the start of an International Space Station resupply mission and a bold attempt to recover the rocket intact on an ocean-going platform.

Russia’s Progress M-26M cargo carrier lifted off Tuesday aboard a Soyuz rocket, climbed through clouds and into orbit, then executed an on-time radar-guided docking with the International Space Station six hours later. See photos of the supply ship’s launch.
