Besxar has successfully completed its first suborbital mission, demonstrating the viability of its technology for manufacturing semiconductors in space. The flight, which took place on July 5, utilized a SpaceX Falcon 9 rocket to carry experimental hardware and wafers above the Kármán line.

What Happened

The mission flew alongside a batch of Starlink satellites, serving as a piggyback opportunity to test Besxar's proprietary canisters. These canisters are designed to allow the natural vacuum of space to enter while preventing contamination from atomic oxygen, a common hazard in Low Earth Orbit (LEO). The flight carried semiconductor wafers from Besxar, as well as samples for researchers at the University of Virginia and the University of Texas at Austin.

According to CEO and founder Ashley Pilipiszyn, the primary goal was to prove that the hardware could keep wafers safe throughout the entire flight profile, including re-entry. "If we can’t keep it clean and protect the wafers, nothing else matters," Pilipiszyn told Payload. The mission provided critical flight heritage for the company's design, confirming that the canisters maintained their integrity and cleanliness standards during the suborbital arc.

Why It Matters

Semiconductor manufacturing requires a vacuum environment, which terrestrial facilities achieve through expensive pumping systems. Pilipiszyn noted that manufacturers invest billions of dollars to create these conditions on Earth, whereas in space, the vacuum is free. Besxar aims to leverage this advantage to produce higher-quality, lower-cost semiconductors in orbit that are then returned to Earth for sale.

This mission marks the first of 12 suborbital flights that SpaceX is under contract to fly for Besxar. Unlike some competitors who develop their own re-entry systems, Besxar is outsourcing re-entry technology to its launch provider. For this initial test, the wafers re-entered aboard the same Falcon 9 booster that launched them. As the company expands to longer in-space manufacturing missions, Pilipiszyn indicated that Besxar’s canisters will be integrated into vehicles such as Starship for launch, in-space operations, and re-entry.

The Bottom Line

Besxar has validated its vacuum-sealing and contamination-protection hardware through a successful suborbital flight on a SpaceX Falcon 9. With a $9.35M seed round led by Dauntless Ventures, the company plans to launch its second mission before the end of the year, continuing its contract for 12 total flights with SpaceX.
