Dropping in twice from a dozen miles excessive within the stratosphere, a paraglider safely touched down on Earth in a key milestone aimed toward eradicating space particles.
The high-altitude checks in April 2022 have been the flying begin to Outpost Applied sciences’ imaginative and prescient: to softly return used space {hardware} again to Earth for reflight or examination. That {hardware} may very well be satellites low on gas, or used-up science experiments on the International Space Station (ISS).
There’s an pressing want to assist with each industries. Satellites are quickly cluttering up low Earth orbit and including space debris that threatens the infrastructure we want for climate forecasts and telecommunications. In the meantime, the ISS is so crowded with 20 years of outdated experiments and tools that it’s operating out of room to host new ones; cargo ships can not empty it quick sufficient any extra.Â

“I consider that what we’re what we’re creating will principally put an finish to space particles,” Outpost CEO Jason Dunn informed Area.com in December 2022. NASA is taking note of that: the company awarded Outpost an early-stage contract (opens in new tab) on Dec. 6 to design a “Cargo Ferry” model of Outpost’s know-how focused for ISS payload return.
Dunn pledges the ferry can be prepared lengthy earlier than ISS is scheduled to retire in 2030, to carry dwelling smaller experiments that usually are accomplished inside just a few weeks of arriving on the large advanced. Bigger payloads would nonetheless be flown dwelling on conventional cargo ships, like SpaceX’s Dragon, he stated.
Dunn is aware of the ISS by his first main orbital enterprise, Made In Area, which he based in 2010. The corporate is finest identified for co-producing the first 3D printer for the ISS. Mockingly, the printer continues to be caught in orbit awaiting a cargo ship slot regardless of the Smithsonian Establishment pledging to take it when it comes dwelling.
The space ferry challenge was born not solely to return {hardware} like that, however to cope with the continuing downside of space launching prices and space particles, Dunn stated. “As I obtained extra concerned within the space trade and my profession, just a few issues have been nagging at me … a lot effort, a lot cash was being put into getting issues off the planet, and hardly any effort in getting issues again to the planet.”

Historically, Dunn stated, we proceed to provide throwaway “single mission” gadgets for space that then must be introduced again to Earth. That’s slowly altering with the introduction of reusable rocket phases by way of Blue Origin and SpaceX, and early-stage satellite refueling first demonstrated in-orbit in 2020. However Dunn stated extra needs to be accomplished, which impressed him to begin Outpost.
“I am an enormous believer within the thought of hundreds of thousands of individuals residing and dealing in space one day, and we, frankly, aren’t going to have that occur if if we do not chart a greater path,” Dunn stated.
The plan is to fetch the satellites in orbit with a small automobile after which to information them by the environment by way of a paraglider, at subsonic speeds; this may permit for an intact touchdown on Earth with out the {hardware} burning up within the environment. To bolster the enterprise case (and revenue), Outpost would fly up satellites throughout launch for deployment, then decide up older satellites in the identical orbit to return to Earth.
“We robotically information the paraglider and the satellite to a touchdown web site, and in precision touchdown flight checks that we have accomplished, we have been inside 5 meters [16 feet] of our goal,” Dunn stated. By comparability, NASA’s profitable take a look at of a “flying saucer” inflatable Mars heat shield excessive in Earth’s environment in November got here down inside 10 miles (16 kilometers) of its touchdown goal.
Thus far Outpost’s concepts are in early designs and checks, however the firm is rising shortly to fulfill forecast demand. Now standing at 14 workers from simply two a yr in the past, Outpost raised $7 million in seed funding (opens in new tab) final summer season on the power of their reusable satellite ventures. And as new space stations seemingly change the ISS within the 2030s, Dunn says, Outpost in all probability can contribute to their cargo wants as nicely.Â
