Orbit is the satellite launch system currently being developed in the US by Sir Richard Branson.
This system intends to despatch rockets to space from under the wing of a converted Virgin Atlantic jumbo jet.
The investment offer is dependent on Spaceport Cornwall and Virgin Orbit putting together the business case.
If everything comes together, however, it could see the jet, called Cosmic Girl, operating out of Newquay in the early 2020s.
“We’re eager to fly from lots of places, to have hubs and gateways to key orbits,” explained Will Pomerantz, vice president for special projects at the Long Beach, California-based company.
