ESA ‘Bakes’ Mars Parachute To Prevent Contamination
A European robotic rover named Rosalind Franklin is gearing up for a historic mission to search for signs of life beneath the surface of Mars. Scheduled for launch in 2028 and landing in 2030, the rover will drill up to 2 meters underground, where radiation cannot destroy potential ancient biological traces. However, to ensure scientists do not accidentally pick up hitchhiking Earth germs instead, the European Space Agency (ESA) recently carried out a bizarre sterilization test.
Under international “planetary protection” rules, space agencies must prevent Earth’s microscopic organisms from contaminating other pristine worlds. If sneaky microbes traveled across space, they could interfere with delicate scientific data or accidentally disrupt the alien environment. To meet these standards, engineers treated a key landing parachute in a specialized high-temperature test. The 35-meter-wide parachute, made of ultra-strong Kevlar fabric and weighing 74 kilograms, was carefully heated inside a special oven. It underwent a grueling 36-hour bake at 125 degrees Celsius following a careful 50-hour preheating process.
The process ensures the landing system is fully sterilized before launch. Engineers say the extreme cleaning step helps guarantee the rover reaches the Red Planet free of Earth-based contamination, allowing scientists to search for life with greater confidence in the mission’s results.
