Where It Goes

What Your Donation Supports

Donations support the San Diego Space Institute (501(c)(3) public charity) and its applied aerospace research programs. Contributions are directed toward the Sentinel-Bio+ technology maturation ladder, a structured three-phase program that takes the mission from sensor development to flight-ready operations.

General Donation

Support SDSI's applied research programs broadly. Contributions are directed at the institute's discretion toward the areas of greatest need across all programs.

SDSI is a 501(c)(3) public charity (EIN 39-2191995). All donations are tax-deductible.
