Varda Space Industries achieved a major milestone on June 23, 2025, with the successful return of its W-4 reentry capsule to Earth. The capsule, launched by SpaceX, carried payloads designed to utilize microgravity for advancements in human health technologies. This marks a significant step in in-orbit manufacturing.
The W-4 capsule, upon reentry, endured temperatures reaching 7,000 degrees Fahrenheit. This was made possible by a heat shield constructed from C-PICA, a lightweight ablative material developed at NASA's Ames Research Center. The technology transfer from NASA to Varda highlights the potential for growth in the U.S. orbital economy.
This mission showcases the successful collaboration between NASA and emerging space companies. It exemplifies how technology and knowledge can be transferred to foster innovation. The success of Varda's mission paves the way for future in-space manufacturing endeavors.
