LightSail 2 is Ready for Launch



Jason Davis • June 24, 2019

Greetings from Kennedy Space Center, Florida, where the Planetary Society is onsite for the launch of LightSail 2! This afternoon we got an up-close look at the SpaceX Falcon Heavy rocket that will carry 24 spacecraft to orbit as part of the U.S. Air Force's STP-2 mission. Liftoff is set for 23:30 EDT (03:30 UTC), the start of a 4-hour launch window.

The rocket's two side boosters still bear their scorch marks from April's Arabsat-6A mission, during which both boosters successfully flew back to Cape Canaveral for upright landings. The center core is pearly white, having never flown.

You can watch tonight's live launch on our homepage at planetetary.org. SpaceX typically starts their webcast about 20 minutes before liftoff. For more information, see our LightSail 2 mission page and our What to Expect When LightSail 2 Launches in Space article

Go Falcon Heavy! Go Prox-1! Go LightSail 2!
