The Deployable Dust Cover was developed for integration with the University of Arizona's Thermal and Evolved Gas Analyzer (TEGA), a combination high-temperature furnace and mass spectrometer onboard the 2007 Phoenix Mars Lander Mission.
- Sealed protection. The cover used a magnetic seal to protect the TEGA instrument from contamination by airborne dust before it was ready to accept samples.
- Mission-driven design. The TEGA Dust Cover contained no materials that could possibly compromise the instruments’ results. Deploying the cover produced no particulates that could find their way into the TEGA oven chambers.
- Reliable operation. Paraffin actuators provided reliable operation for this mission-critical hardware.
