SpaceX is set to launch a rocket Monday night from Cape Canaveral for the first time in six months.
The company's flights have been on hold since a rocket exploded in June, which was blamed on a weak strut.
SpaceX is also trying to safely land a rocket after a flight. If successful, it would be first in history this maneuver will be executed.
The Falcon 9 rocket will send 11 communication satellites into space that will be deployed about 20 minutes after liftoff.
The company says Monday night’s launch is scheduled for 8:33 p.m.
Launch & landing can be seen on the https://t.co/bDd3GxQXMC webcast or in person from Cape Canaveral public causeway at 8:33pm local tmrw
