Startup wants to launch satellites with slingshots instead of rockets

Trans-orbital rocket launches can be expensive, and wasteful. That's why a newish company called SpinLaunch has envisioned an alternative: a giant centrifugal slingshot that basically whips the satellite around for an hour until it reaches 5000 mph, then launching it through a tube and up into the atmosphere. If this works out, they say it could potentially reduce the cost of space launches by a factor of twenty.

Though the company launched in 2015, they just completed their first successful test launch on October 22, 20221 from its Spaceport America base in New Mexico.
