The company is targeting Sunday (May 24) for its Launch Demo mission, with a backup opportunity on Monday (May 25). The four-hour window will open each day at 1 p.m. EDT (1700 GMT), Virgin Orbit representatives announced today (May 20).
Launch Demo will be a huge milestone for Virgin Orbit, which has been developing its air-launch system for five years. That system involves a modified Boeing 747 jet called Cosmic Girl and a 70-foot-long (21 meters) rocket known as LauncherOne, which is capable of delivering about 1,100 lbs. (500 kilograms) to a variety of destinations in low Earth orbit.
If the launch succeeds, than Virgin Orbit will stand ready to begin commercial launches later this year.
