Tyvak, a manufacturer of small satellites, disclosed new details Monday about an experimental spacecraft launched aboard a SpaceX Falcon 9 rocket Saturday, revealing plans to validate compact optical telescopes that could offer a new way to monitor space traffic and orbital debris.
The small satellite, named Tyvak 0130 and weighing about 25 pounds (11 kilograms), launched Saturday from NASA’s Kennedy Space Center in Florida with a cluster of 52 Starlink internet satellites and a radar observation craft from Capella Space.
A spokesperson for Tyvak Nano-Satellite Systems, based in Irvine, California, said Monday that the small Tyvak 0130 satellite carries optical telescopes capable of black-and-white and color imaging. The telescopes were developed in collaboration with Lawrence Livermore National Laboratory, according to Tyvak.
The Tyvak 0130 satellite is based on a 6U CubeSat platform. The main body of a 6U CubeSats is typically about the size of a briefcase.
Tyvak said the new satellite builds on lessons learned from Tyvak 61, a smaller 3U CubeSat launched in 2018. Tyvak 61, also known as GeoStare, tested the performance of monolithic telescope design that could be used to collect remote sensing data for Earth observation, astronomy, and space debris tracking applications.
The monolithic telescope replaces the primary and secondary mirror structures in standard telescopes with one solid piece of glass, according to Tyvak and LLNL, with optical shapes and reflective coatings at both ends of the glass.

LLNL’s monolithic telescope design does not require precise alignment between two separate mirrors to ensure proper focusing, simplifying the design and allowing a smaller, less expensive spacecraft to carry the monolithic telescope, officials said.
Tyvak 61 “produced exceptional imagery of stellar fields and ground targets in the visible spectrum,” the Tyvak spokesperson said.
The larger Tyvak 0130 satellite launched Saturday can accommodate twice the number of telescopes as the Tyvak 61 testbed. The new spacecraft is now in its commissioning phase, according to Tyvak.
Tyvak 0130 feature improvements to better track space objects and debris, and can see in multiple wavelengths simultaneously, Tyvak said.
“Once on-orbit performance validation is completed, Tyvak 0130 will be the most optimized commercial Space Situational Awareness (SSA) satellite available in the market today,” the company said.

Tyvak’s cooperative agreement with LLNL allows the smallsat company to commercialize the monolithic telescope technology. The agreement also gives Tyvak the option to license LLNL’s intellectual property associated with the miniature telescope design.
The monolithic telescopes can range in size from one inch to 14 inches (2.5 centimeters to 35.5 centimeters), according to Tyvak. They can fit on a range of small satellites ranging from nanosatellites to microsatellites that can weigh several hundred pounds.
Tyvak 0130 is on the smaller end of the spectrum.
“The MonoTele nanosatellite imaging payloads can be used across multiple applications and will serve Earth observation, space situational awareness, and satellite navigation initiatives,” Tyvak said in a statement last year announcing the agreement with LLNL.
