Virgin Orbit is wasting no time in 2021 getting back to active flight testing: The company has a window for its next orbital demonstration launch attempt that opens on Sunday, January 10, and that continues throughout the rest of the month. This follows an attempt last year made in May, which ended before the LauncherOne rocket reached orbit — shortly after it detached from the Cosmic Girl carrier aircraft, in fact.
While that mission didn’t go exactly as Virgin Orbit had hoped, it was a significant milestone for the small satellite launch company, and helped gather a significant amount of data about how the vehicle performs in flight. LauncherOne was able to briefly light its rocket booster before safety systems on board automatically shut it down. The company had been looking to fly this second test before the end of last year, but issues including COVID-19 meant that they only got as far as the wet dress rehearsal (essentially a run-through of everything leading up to the flight with the vehicles fully fueled).
This next mission will once again attempt an orbital launch, and this time, the stakes are somewhat higher because actual customer payloads from NASA are on board. They include a number of small satellite science experiments and demonstrations, and while they’re specifically selected for the mission profile (meaning it’s not a tremendous loss if the launch fails), it still would make everyone happiest to actually get them to their target destination.
The nature of the launch window means that Virgin Orbit will likely wait for conditions to be as good as possible before taking off from the Mojave Air and Space Port in California, so take that January 10 date as the earliest possible launch time, but not necessarily the most likely. If successful, Virgin Orbit will join a select group of private small launch vehicles that have made it to orbit, so the industry will definitely be watching the next time Cosmic Girl takes off with LauncherOne attached.
