Watch European Area Company Check Its Mars Rover Parachute


Regardless of what you may think, the trickiest a part of sending a rover to Mars isn’t the journey by house — it’s slowing down and touchdown when you arrive there. Mars’s skinny ambiance makes slowing utilizing a parachute troublesome, which is why Mars missions are usually geared up with very giant and high-tech parachutes to assist rovers contact down gently on the pink planet.
The European Area Company (ESA) and Roscosmos will likely be sending their ExoMars rover to Mars in 2022, they usually lately carried out a high-altitude take a look at of the rover’s parachute. However there have been issues in the course of the take a look at, with one of many two parachutes being broken when the pilot chute indifferent. The workforce will likely be checking knowledge and making changes within the hope of fixing the problem earlier than the subsequent take a look at later this yr.

ESA carried out two exams of the system over June 24 and 25, taking the parachute to an altitude of 29 km (18 miles) utilizing a helium balloon and dropping it together with a dummy descent module which simulates the dimensions and weight of the rover as it is going to land. The parachute has two levels: A 15-meter-wide first stage which opens whereas the car remains to be touring at supersonic speeds, and a 35-meter-wide second stage, which slows the car additional.
“We’re very completely happy to report that the primary important parachute carried out completely: We have now a supersonic parachute design that may fly to Mars,” stated Thierry Blancquaert, ExoMars program workforce chief.
Relating to the problem with the second parachute, Blancquaert went on to say, “The efficiency of the second important parachute was not excellent however a lot improved, due to the changes made to the bag and cover. After a easy extraction from the bag, we skilled an sudden detachment of the pilot chute throughout closing inflation. This seemingly implies that the primary parachute cover suffered further stress in sure elements. This created a tear that was contained by a Kevlar reinforcement ring. Regardless of that, it fulfilled its anticipated deceleration and the descent module was recovered in good state.”
The workforce hopes to have this concern resolved prepared for the subsequent testing part, which is scheduled to happen in October or November this yr in Oregon.
