Besxar completes inaugural flight with SpaceX

Reporting the results of its Flight-1 ‘Mission Asimov’, Washington DC-based Besxar (which is developing the manufacturing of advanced semiconductor materials in space) says that, on 5 July, two of its ‘Clipper-class’ canisters flew from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida aboard a SpaceX Falcon 9 first-stage booster and were recovered intact after the booster returned to land.

Besxar’s reusable Fabships reached about 71 miles in altitude (past the internationally recognized edge of space) and the mission concluded about 11 minutes after liftoff.  

It was the first flight carrying custom wafer cartridges, power, avionics, and printed-circuit hardware that Besxar designed and built in-house, all of which qualified on the first attempt.

The mission carried gallium nitride (GaN)-on-sapphire, undoped silicon, and bare sapphire wafer samples from Besxar, in addition to gallium arsenide (GaAs), and aluminum indium arsenide antimonide (AlInAsSb) wafers from academic research partners at the University of Virginia (UVA) and the University of Texas at Austin (UT Austin).

Flight outcomes

Besxar’s primary test objective for Flight-1 was the viability and performance of the canister design in admitting vacuum, i.e. does it work as a cleanroom? The canister needed to (1) maintain structural integrity through all phases of flight, re-entry, and recovery; (2) allow vacuum into the canister during flight to expose test materials; and (3) prevent contaminants from entering the canister. Post-flight testing indicates that Besxar’s canisters performed as expected.

Besxar also tested the canister design’s ability to carry wafers safely through the entire flight profile. The canisters flew multiple wafer samples of varying compound semiconductor materials, and initial analysis indicates that none sustained damage. Besxar engineers examined the wafers and canister interiors against pre-flight markers and found no cracking, no warping, and no visible damage. Substrates flown for UVA and UT Austin are currently undergoing independent analysis at the material level that may yield additional data on the effects of vacuum exposure on compound semiconductor materials and their manufacturability. 

Besxar’s ultimate in-space manufacturing process will be fully autonomous, which requires significant real-time data and testing infrastructure. The firm built the initial foundation of that data collection system for Flight-1 and will expand it across subsequent flights and, eventually, operations. The data system performed well. Besxar was able to collect pressure, acceleration, thermal, vibration and shock data for the entire mission. One canister performed nominally; the second canister had an anomaly when recording flight data. Besxar is completing its anomaly review and closeout ahead of the next flight.

“In just nine months, we’ve been able to design and test initial key capabilities for our in-space compound semiconductor wafer manufacturing technology,” says founder & CEO Ashley Pilipiszyn. “We proved that the hardware is viable and that our systems can survive the extreme swings of spaceflight. Now, we have real data and, more importantly, a team with payload integration, spaceflight, and recovery heritage that will only accelerate our work as we take on the next set of technical milestones on our roadmap.”

Mission plans

Flight-1 was the first of 12 contracted missions under Besxar’s launch agreement with SpaceX. Mission Asimov clears the way for the next set of key technical milestones toward in-space compound semiconductor manufacturing. Besxar says that it will apply what it learned and iterate quickly toward Flight-2.

Mission Asimov and future flights are financed by Besxar’s early investors. Ahead of the mission, the firm raised a $10.3m seed round led by Dauntless Ventures alongside Overture VC, Keymaker VC, 645 Ventures, Singh Capital Partners, Koru Capital, Plum Alley Ventures, Mana Ventures and Earthrise VC, bringing total funding to $14.7m.
