With less than 24 hours to go until launch, the weather is doing its part to cooperate.

The U.S. Air Force 45th Weather Squadron is continuing to predict an 80% chance of favorable weather conditions for the Thursday, July 30, liftoff of a United Launch Alliance Atlas V rocket, carrying NASA’s Mars 2020 Perseverance rover. Primary weather concerns for launch are cumulus and thick clouds.

Perseverance is scheduled to blast off tomorrow morning from Space Launch Complex 41 at nearby Cape Canaveral Air Force Station in Florida. The two-hour window opens at 7:50 a.m. EDT. NASA’s Launch Services Program, based at Kennedy Space Center, is managing the launch.

Tune in to NASA Television or the agency’s website today at noon to view a briefing with NASA Administrator Jim Bridenstine, live from Kennedy. Follow along at for a recap of this afternoon’s event, as well as a preview of live countdown and launch coverage, starting tomorrow at 7 a.m.
