SpaceX is getting ready to test reentry vehicles that could be used for in-orbit manufacturing, tapping into a potentially lucrative industry that’s slowly gaining momentum. The Federal Aviation Administration (FAA) approved test flights of SpaceX’s Starfall, an uncrewed capsule designed to perform research and development in the microgravity environment, as well as provide point-to-point cargo delivery. SpaceX has shared little information about Starfall, but recent FAA documents reveal some new details about the ongoing project. An early look at Starfall Bloomberg first reported on the Starfall program last year, describing plans to use SpaceX’s Starship rocket to launch the capsules and develop commercial products, like pharmaceutical components, in space. Based on the FAA documents, the capsules are shaped like a disk measuring 10.2 feet (3.1 meters) wide and 2.5 feet (0.75 meters) tall. They are made of an aluminum top plate and a carbon-fiber heat shield to protect the payload during reentry. The capsules will be able to carry up to 2,205 pounds (1,000 kilograms) worth of payloads each within a volume of 8.2 by 4.9 by 1.6 feet (2.5 by 1.5 by 0.5 meters). SpaceX plans on using either its Falcon 9 or Starship rocket to launch the capsules to orbit. The capsules will complete reentry using a single main parachute, along with pilot and drogue parachutes, while the heat shield jettisons off before splashdown.
