Tomographic Experiment Using Radiative Recombinative Ionospheric EUV and Radio Sources
TERRIERS was a student-built NASA space-science mission led by Boston University to reconstruct three-dimensional views of Earth's ionosphere. Its ultraviolet and radio measurements were intended to improve understanding of upper-atmosphere variability and the space-weather conditions that disrupt terrestrial communications.

- Launch Site
- Outcome
- TERRIERS reached its intended orbit, but an attitude-control polarity error pointed its solar array 180 degrees away from the required direction. The spacecraft exhausted its battery roughly ten hours after launch and never returned science data, resulting in complete mission failure.
