SpaceX is going to launch a Falcon Heavy rocket for only the third time ever tonight, should all go according to the current mission plan. The launch, set to take place during a four-hour launch window that opens at 11:30 PM EDT (8:30 PM PDT) tonight, will lift off from Launch Complex 39A at Florida’s Kennedy Space Center.
On its first-ever nighttime launch, Falcon Heavy’s STP-2 mission will carry a cargo made up of a number of payloads from commercial customers, as well as from the U.S. Department of Defence, the National Oceanic and Atmospheric Administration (NOAA) and NASA. The mission involves putting 24 different spacecraft into orbit, along three separate orbital paths. One of the is an experimental research satellite for the Air Force Research Laboratory, and NASA’s payload includes four different experimental craft, which the agency detailed last month.
It’ll also carry LightSail 2, a crowdfunded spacecraft spearheaded by Bill Nye’s Planetary Society, which will make its way through space using the literal solar wind beneath its massive sail. SpaceX is also re-using Falcon Heavy boosters for the first time, with side boosters used on the Arabsat-6A mission flown in April, and it’ll attempt to recover all three first-stage rockets via landings at Cape Canaveral and aboard its drone landing pad barge.
The launch will be streamed live above, with the feed getting started around 15 minutes prior to scheduled launch window opening.
