Mars Rover Addresses Parachute Damage Problem That Delayed Launch To 2022


A “new parachute strategy” is in place to let the Rosalind Franklin rover lastly go away for Mars in 2022, in accordance with a mission replace.

The European Space Agency and companion Roscosmos made the robust name virtually precisely a yr in the past to delay the mission, the newest within the ExoMars collection, from a launch in 2020. Missing the launch window meant they lose the prospect to reach at Mars with NASA’s Perseverance rover in February, nevertheless it was a vital determination.

What troubled mission managers final March was a collection of parachute issues, compounded with the emergence of the novel coronavirus pandemic that made testing much more tough than normal.

But everybody has been exhausting at work (with security precautions) within the months since. Recently, ESA completed two balancing checks in Cannes, France, together with a composite spacecraft spin take a look at producing an acceleration equal to twice Earth’s gravity. They carried out simulated rover operations in Turin, Italy. And on the parachute facet, there’s been plenty of progress, the company mentioned within the replace.

ESA requested a second producer to supply canopies for a brand new high-altitude drop take a look at in May or June this yr in Sweden, to ensure all the pieces is working appropriately. The new producer is Airborne Systems, the identical firm that helped get Perseverance to Mars on Feb. 18, and they’ll help parachute maker Arescosmo.

Parachute injury issues hold cropping up throughout testing, occurring once more in November 2020 — however ESA mentioned the issue is much less extreme than the checks in 2019, indicating progress. Now there’s a plan to deploy even “stronger and more robust” parachute canopies subsequent time, together with redesigned baggage and a brand new packing process that ought to reduce any tangles throughout deployment.

Since there’s just one probability to land safely on Mars, ESA plans yet one more high-altitude take a look at in Oregon someday between September and November. A last, optionally available testing alternative is scheduled for February or March in Oregon, if wanted. In between these drop checks, ESA will use a floor facility to confirm any modifications to the parachute design.

The company is being extra-careful because it hasn’t made it to Mars’ floor safely but; the Schiaparelli take a look at car could have exploded upon impression in 2016, and the Beagle 2 mission failed to phone home after its 2003 try.

“High altitude drop tests require complex logistics and strict weather conditions, making them difficult to schedule,” ESA defined. “The ground tests can be repeated on a quick turnaround, buying significantly more time in the test campaign and reducing risk by allowing more tests to be conducted on a short time frame.”

Rosalind Franklin will probably be a vital addition to Mars efforts, serving to with ongoing searches for indicators of life on the Red Planet. NASA and the European Space Agency are additionally planning a pattern return mission as quickly as this decade, to get attention-grabbing rocks from Mars into high-end laboratories on Earth. But that pattern return mission will depend upon funding, technical know-how and political will; Rosalind Franklin is probably going a vital piece in proving the subsequent mission can go forward.
