Tyvak 61C

Tyvak 61C [Tyvak]

The Cubesat known by the manufacturers designation Tyvak 61C is built to the 3U CubeSat form factor and is to teste an optical telescope system that can be used for Earth and space observation and to catalog variability of luminous stars.

The instrument built by the Lawrence Livermore National Laboratory (LLNL) is a lightweight telescope, which measures as small as 8.5 centimeters in diameter and is so compact that the satellite it is mounted on can be smaller than traditional space vehicles. It is a high-resolution monolithic optical telescope systems, fabricated from a single piece of fused silica, for deployment on small satellites. The satellite is built by Tyvak.

This demonstration system, which was launched in early 2018 into low-Earth orbit, has produced excellent imagery of both stellar fields and ground targets. Potential applications under consideration for the low-cost imaging system include commercial and government Earth observation, space debris detection and tracking and astronomical science observations.

One advantage of the telescope is that it can take images of space in daytime and night during its 95-minute orbit of Earth, whereas terrestrial telescopes can only take images at night.
