Pandora, the latest in a long portfolio of University of Arizona's space science missions, has cleared its last major milestone on its journey into space. This week, Pandora—a satellite about the size of fridge—was mounted inside the launch vehicle, a SpaceX Falcon 9 rocket. Pandora now awaits blast-off from Space Launch Complex 4E at Vandenberg Space Force Base in California. The launch window opens at 6:19 a.m. Arizona time (8:19 a.m. EST) on Sunday, Jan. 11. SpaceX will provide a livestream of the event.
