The rover is scheduled to launch at 7:50 am ET from Cape Canaveral, Florida. You can watch it LIVE here.
So far, reports from the 45th US Air Force Weather Squadron predict an 80% chance of favorable conditions for launch this Thursday morning. The biggest concern is thick clouds.
If the rover does not launch at that time, it will be possible to do so every five minutes during a two-hour window this morning. And if the launch is delayed beyond Thursday, there is a two-week window in which Perseverance can launch and will end on August 15.
