46.030 UO Terrier-Improve Malemute sounding rocket was launched from Wallops Island, VA on August 19, 2021. RockSat-X student experiments are developed with an objective of providing students with an enhanced experience of flying experiments that are exposed to the space environment. The students gain experience in designing, building, testing, and then flying their experiments on a sub-orbital space flight. It also exposes students to the design and mission lifecycle. The payload was recovered and the experiments returned to the students.

The RockSat-X missions carry student developed experiments and is a follow on mission to RockOn and RockSat-C. RockSat-X experiments are more advanced than RockOn and RockSat-C and include full featured sounding rocket support systems, such as telemetry, attitude control and recovery. RockSat-X experiments are exposed to the space environment enabling measurement of variables outside the payload. The Principal Investigator was Mr. Chris Koehler/Colorado Space Grant Consortium.
