NASA and SpaceX will try to launch their new planting-hunting satellite Wednesday night.
Monday's launch was canceled as both agency's performed more testing on the "Transiting Exoplanet Survey Satellite" or "TESS." SpaceX wanted to analyze the rocket's guidance, navigation and control systems.
Once in orbit, Tess will search for planets that might support life orbiting bright stars.
The launch is set for 6:51 p.m. ET. You can watch a live stream of the launch here.
