ASUSat (Arizona State University Satellite, also known as ASU-OSCAR 37) was a U.S. amateur radio satellite that was developed and built for educational purposes by students at Arizona State University.

ASUSat was launched on January 27, 2000, along with JAWSAT with a Minotaur I rocket from Vandenberg Air Force Base, Lompoc, California.

ASUSat was received 50 minutes after the start in South Africa, later also in New Zealand and the United States.

A problem with the power supply was reported on the third pass, 14 hours after take-off.

The solar cells did not provide any electrical energy, so the batteries were exhausted shortly afterwards.
