GeoStare 2 or Tyvak 0130 is an optical spectrum astronomical observation satellite built by Tyvak on the CubeSat (6U) form factor.
Two telescopes that make up Tyvak-0130?s GeoStare 2 payload are producing super high-resolution images in a small form factor at a low cost
The satellite carries a miniature space telescope called MonoTele for possible commercial use. The technology was developed by Tyvak Nano-Satellite Systems and the Lawrence Livermore National Laboratory under a four-year agreement to advance compact telescopes for commercial applications. It is a high-resolution monolithic optical telescope system, fabricated from a single piece of fused silica, for deployment on small satellites. It is highly compact and extremely robust against vibration loads and temperature swings. It is the third flight of such a miniature telescope after GeoStare and Pathfinder Risk Reduction.
