The Mission
What Sentinel-Bio+ Does
Sentinel-Bio+ is a planned constellation of small satellites designed to measure space radiation and atmospheric drag in low Earth orbit. The data supports NASA, satellite operators, and government agencies that need reliable space-environment measurements to manage operational risk.
The Sun is nearing the peak of Solar Cycle 25, and the number of satellites in orbit is growing rapidly. Reliable radiation data is critical for protecting astronauts, managing satellite lifetimes, and planning future missions.
The program is selected and funded by the NASA California Space Grant Consortium. San José State University is developing the spacecraft with guidance from SDSI mentors, following NASA systems engineering processes from design review through hardware testing.
