After decades of trial and error, launch operators are getting pretty good at sending things into space. The Falcon 9 is such a reliable workhorse that it’s now more newsworthy when something goes wrong than right. China is rapidly deploying megaconstellations that may rival the scale of SpaceX’s Starlink, all while building out new rockets with what the Chinese space industry claims will be better capabilities. That’s not to say that launch and space access are fully sorted, but things are coming along.


Receiving much less attention until recently is downmass, or the ability to send (intact) cargo back to Earth through controlled reentry shipments.


Some companies, such as Varda Space Industries, have been making headway. That company recently completed its sixth reentry mission, landing a capsule intact at the Koonibba Test Range in South Australia. These capsules and others like them would provide a means for in-space manufacturing, cargo delivery and biomedical or pharmaceutical research in microgravity.


Now, with newly-published Federal Aviation Administration documents, it appears that SpaceX is serious about getting in the game. The agency approved two test reentries for SpaceX’s Starfall, a cargo reentry vehicle that was first disclosed last July but not discussed publicly until now. Thus far, there’s no public information on when these tests will happen. But the documents suggest that, in typical SpaceX fashion, the company plans to push the concept hard with mass deployment of reentry vehicles after the testing phase.


This mass deployment may bring not only competition but potentially disruption to other downmass companies like Varda — which has been relying on SpaceX to launch its capsules.


These reentry capsules may not revolutionize the space industry overnight but could someday be as broadly ubiquitous as Falcon 9’s reusability is today. Aside from microgravity research and point-to-point delivery, technology that turns space traffic into a two-way street could enable use cases or growth in the in-space economy that the industry isn’t even thinking about yet, providing new tools for the trade.

SPACE UNICORNS


Speaking of Iceye, that fundraising round prompted the SpaceNews editorial team to update the newly published list of space unicorns, first compiled for the June issue of SpaceNews Magazine.


Iceye, already on the list of unicorns — startups that have reached a value of $1 billion or higher — leapt to the top of the list, now holding the highest disclosed valuation among all space unicorns and one of the highest amounts fundraised in total.

SpaceNews counts 30 space unicorns across the global industry in a list compiled from independent research and industry sources, company and government disclosures and other intelligence. (One less after SpaceX’s IPO expected Friday.) This list, assembled in the absence of a widely accepted global list of space unicorns, will become an ongoing project, updated as more companies cross the $1 billion threshold —  a feat that’s occurring at an increasingly rapid pace.
