ExoMars 2020 Parachute Tests
A series of ground-based tests designed to check the extraction of the ExoMars 2020 mission’s parachutes from their bags have started successfully with promising results to keep the mission on track for next year’s launch.
Cooperation with NASA has provided access to special test equipment at NASA’s Jet Propulsion Laboratory enabling ESA to conduct multiple dynamic extraction tests on the ground to validate the new design adaptations prior to the upcoming high-altitude drop tests. The ground tests mimic the high speeds at which the parachutes will be pulled from their bags during the descent phase at Mars.
Calibration tests, including low-speed extraction tests at around 120 km/h on both main parachutes and the first high-speed extraction test at a targeted speed of just over 200 km/h on the first main parachute, have already been completed. The low-speed tests were crucial to verify the stability of the new parachute bag design, while the high-speed tests mimic that at which the parachutes will be pulled from their bags during the descent phase at Mars.

About the team
All parachute system qualification activities are managed and conducted by a joint team involving the ESA project (supported by Directorate of Technology, Engineering and Quality expertise), TAS-I (prime contractor, in Turin), TAS-F (PAS lead, in Cannes), Vorticity (parachute design and test analysis, in Oxford) and Arescosmo (parachute and bags manufacturing, in Aprilia). NASA/JPL-Caltech has provided engineering consultancy, access to the dynamic extraction test facility, and on-site support. The extraction tests are supported through an engineering support contract with Airborne Systems, who also provide NASA’s Mars 2020 parachutes, and by Free Flight Enterprises for the provision of parachute folding and packing facilities.
The ExoMars programme is a joint endeavour between ESA and Roscosmos. In addition to the 2020 mission, it also includes the Trace Gas Orbiter (TGO) launched in 2016. The TGO is already both delivering important scientific results of its own and relaying data from NASA’s Curiosity Mars rover and InSight lander. It will also relay the data from the ExoMars 2020 mission once it arrives at Mars in March 2021.
