SpaceX is launching its Falcon Heavy rocket tomorrow, and if it’s successful, it’ll be twice as powerful in terms of cargo capacity as its next closest active rival. That will help give SpaceX an edge in the growing private space race, and open up new opportunities in terms of potential clients, as well as set the stage for traveling to Mars.

The launch itself is happening on Tuesday, February 6 at 1:30 PM EST, weather permitting. The window lasts until 4 PM EST, however, so if conditions are good within that time the launch should go off as planned. There’s a backup window on February 7, which also starts at 1:30 PM EST, and we’ll be there live to watch it happen and report back all the news right here on TechCrunch.
