Meet the Arc spacecraft: it aims to deliver cargo anywhere in the world in an hour

The test spacecraft, with a mass of about 200 pounds (90 kg) performed well, Fiaschetti said. It demonstrated the capability to raise and lower its orbit, and remains power positive to date, periodically checking in with Inversion flight controllers. However, the spacecraft will not make a controlled landing.
“Ray won’t be coming back,” Fiaschetti said. “We’re doing long-term testing of software on orbit.”
Although Ray did not land, Inversion now feels confident enough in its technology to move into the production of the larger Arc vehicle, which was unveiled on Wednesday evening. About the size of a large table top—Arc is four feet wide and eight feet tall—the company is aiming to launch the first Arc vehicle by the end of 2026. Fiaschetti said Inversion is “on a really good path” to make that timeline.
So what does the military want to ship?
Arc is a lifting body spacecraft, and it will do the majority of its maneuvering in the atmosphere, where it has 1,000 km of cross-range capability during reentry. It will land under parachutes and therefore not require a runway. Because the vehicle’s propulsion system uses non-toxic materials, a soldier can approach it immediately after landing without any protective gear.
So what would the US military want to pre-position in space for delivery at a moment’s notice to any location around the world?
“We like to describe this as mission-enabling cargo or effects,” Fiaschetti said. “This could be a wide variety of specific payloads, anything from medical supplies to drones to what have you. But the key discriminator is, does this make a difference in the moment it’s needed when it gets back down to the ground? You know, for the military and national security, if they need their cargo before the fight is over.”
The company says it has already built a “full-scale manufacturing development unit of the primary structure” for the first Arc vehicle. It would be an impressive capability if the small team at Inversion—now 60 people strong, and growing—can bring the Arc spacecraft to market. If, of course, is the operative word. “Space is hard” may be a cliché, but it also happens to be true.
