Blue Origin will make another attempt to launch its New Glenn megarocket —carrying NASA’s ESCAPADE Mars mission—on Thursday afternoon.

Intense solar storms responsible for breathtaking auroras across the U.S. delayed the launch of Blue Origin’s big new rocket Wednesday.

The 321-foot (98-meter) New Glenn blasted into the afternoon sky from Cape Canaveral Space Force Station, sending NASA’s twin Mars orbiters on a drawn-out journey to the red planet.
