About CASPR

Configurable and Autonomous Sensor Processing Research (CASPR) is designed to enable effective onboard processing for next-generation sensors and applications. CASPR is a Department of Defense payload on the Space Test Program - Houston 7 (STP-H7) pallet aboard the International Space Station. It was developed, designed, and built by the students and faculty of the NSF Center for Space, High-performance, and Resilient Computing at the University of Pittsburgh. Explore below to learn more about this exciting research testbed.

Command Logs

Explore the latest from the students commanding CASPR.

[2024-02-19]:

High temperatures prevent GPU activity today. Boston burst remains on the SSP burst buffer, One target programmed!

[2024-02-12]:

Attempt near Chicago slightly off timing, but still feature rich! Another successful burst near Boston! High thermals affecting GPU today, so downlink slightly delayed.

[2024-02-09]:

Successful burst capture near Plymouth, Massachusetts! Downlink of coastal Japan burst started! Two more targets programmed! Eight bursts onboard CASPR!
