'Drag sail' to deorbit satellites receives $750K in seed funding

A "drag sail" concept designed to help get space junk out of orbit just received a cash infusion.

The Spinnaker concept to deorbit small satellites received $375,000 in seed funding from the investment firm Manhattan West, which NASA will match under its Small Business Innovative Research Phase II-Extended (SBIR Phase II-E) contract.

The combined $750,000 in funding will pivot Vestigo Aerospace's product line to commercial manufacturing, the company said in a Purdue University release (opens in new tab), with the first sales expected in 2023. (The tech is licensed through Purdue.)

The money follows on from numerous discussions in the U.S. space community about space debris in recent weeks, including a fresh pledge to address the growing problem by the Federal Communications Commission and via policy from the Biden administration.

"The Spinnaker product line of drag sails addresses the growing need for reliable end-of-mission deorbit capability … to maintain the sustainability of low Earth orbit," David Spencer, founder and CEO of Vestigo, said in the statement. "Bolt-on dragsails represent an 'ounce of prevention' approach to the orbital debris problem that, if left unchecked, could halt the growth of the orbital economy."

While the tech is early-stage, Vestigo did seek to test out its Spinnaker3 concept in orbit. However, that prototype was destroyed during the debut test flight of Firefly Aerospace's Alpha rocket, which ended with an explosion shortly after liftoff in September 2021.

Once operational, the drag sail should be available for deployment on satellites regardless of whether they are functional or not, Vestigo said. "The drag sails can be deployed on command or via a backup timer, providing reliable deorbit capability even if the host vehicle is inoperative," the release stated.

Spinnaker isn't the only drag sail out there. The first spacecraft to demonstrate similar active space debris-removal technologies deployed from the International Space Station in 2018, and China tested a drag sail of its own in 2022.
