Update, 10:51 PM: Liftoff!

At 10:50 PM ET tonight, SpaceX plans to launch two satellites into orbit with a Falcon 9 rocket that will take off from Cape Canaveral. The launch window extends for 43 minutes, and weather forecasters estimate a 70% chance of favorable conditions.

The payload includes a satellite by Asia Broadcast Satellite, or ABS, and one by Paris-based Eutelsat, both of which will provide broadcast and telecommunications services. What's remarkable about them is their propulsion systems: USA Today says these will be the first sats entirely reliant upon electrical propulsion, not chemical, to reach their proper orbits.

Watch it live here starting at 10:30 PM ET:

Next landing attempt will be 3rd launch from now. Tonight's flight and following one will not have enough propellant. — Elon Musk (@elonmusk) March 2, 2015
