Enhancing Supersonic Parachutes for Mars Exploration
NASA researchers are actively investigating methods to improve the reliability and safety of supersonic parachutes designed for delivering scientific instruments to Mars. The EPIC (Enhancing Parachutes by Instrumenting the Canopy) team at NASA’s Armstrong Flight Research Center is leading a series of research flights to gather crucial evidence that will advance sensor technology for these parachutes.
During a recent flight test in June, a drone successfully air-launched a capsule that deployed a parachute equipped with a flexible, strain-measuring sensor. Remarkably, the sensor was integrated without affecting the parachute’s canopy material, validating the EPIC team’s hypotheses. This successful deployment not only demonstrated the feasibility of the technology but also yielded important data that will inform subsequent tests.
Matt Kearns, project manager for the EPIC initiative, emphasized the importance of reviewing these research flights to shape future steps. “We are speaking with potential partners to come up with a framework to obtain the data that they are interested in pursuing,” he stated. Enhancements under consideration include temperature testing for the sensors, data analysis methods, and further instrumentation for upcoming flight tests.
These initial flight tests mark a significant step toward addressing gaps in current computer models that predict the performance of supersonic parachutes. Beyond improving Mars missions, the insights could foster collaborations with industries such as aerospace and auto racing, which also rely on advanced parachute systems.
This project is funded by NASA’s Space Technology Mission Directorate (STMD) through its Entry Systems Modeling project at NASA’s Ames Research Center in California. The collaborative efforts involved the development of the parachute and capsule system by NASA’s Langley Research Center, with interns at NASA Armstrong contributing to the build and integration of a similar system.
An earlier phase of the EPIC project focused on sourcing commercially available flexible strain sensors and creating an effective bonding method, showcasing the initiative’s dedication to innovation and industry collaboration. As research progresses, the EPIC team remains committed to refining parachute technology that holds promise for future interplanetary exploration.
