At Cape Canaveral's Space Launch Complex-41, loading of the RP-1 fuel aboard the United Launch Alliance Atlas V first stage was finished last night.
Though it was completed late at 9:30 p.m. EDT due to weather conditions, launch preparations are on schedule this morning.
The launch of NASA's Radiation Belt Storm Probes has been confirmed on the Eastern Range for Aug. 30 at 4:05 a.m.
The terminal countdown to load the cryogenic liquid oxygen and liquid hydrogen into the rocket will begin at 1:35 a.m.
The launch weather forecast has improved with a 30 percent chance of not meeting the launch weather criteria on Thursday morning due to cloud conditions.
Atlas V RBSP to Return to Launch Pad Today
First motion today is planned for 2 p.m. EDT. Once at the pad, preparations will begin for the loading of storable propellant aboard the Atlas booster.
