LASARsat (Laser-Assisted Satellite Reentry satellite) is a Czech scientific microsatellite, which was launched on 21 December 2024. The LASARsat mission is a continuation of the Czech high school team LASAR,1 which won the Conrad Challenge, a global STEM competition held in Houston.23 The satellite is designed to test the possibilities of using high-power lasers for traffic management in orbit and to help to solve the problem of space debris.456 LASARsat is 1U specification CubeSat, with dimensions of 10×10×11.3 cm and total volume of 1000 cubic centimeters. The satellite was launched into a Low Earth orbit by SpaceX's Falcon 9 on the Bandwagon-2 mission.78910
Payload
The satellite has control, energy and communication equipment on board, the latter being designed for amateur radio contact.11 LASARsat is also carrying a small capsule with non-alcoholic Czech beer.12

Seven scientific instruments are on board LASARsat:11
- Photodiodes for measuring the laser's energy losses in Earth's atmosphere
- Series of light-emitting diodes (LEDs) for improving tracking accuracy
- Retroreflectors for reflecting the laser beam back to Earth's surface to allow its further study
- Langmuir probe for measuring changes in ionization upon laser's impact
- Earthcam, a camera for capturing the Earth's surface, on which the effects of the laser beam on optical sensors are tested
- Two dosimeters, one supplied by Czech Aerospace Research Centre and the other one by SkyFox Labs
