Ingenuity’s ninth flight offered imagery that may assist the Perseverance rover workforce develop its science plan going ahead.
Photos snapped on July 5 by NASA’s Ingenuity Mars Helicopter on its formidable ninth flight have supplied scientists and engineers working with the company’s Perseverance Mars rover an unprecedented alternative to scout out the street forward. Ingenuity offered new perception into the place completely different rock layers start and finish, every layer serving as a time capsule for a way situations within the historical local weather modified at this location. The flight additionally revealed obstacles the rover could must drive round because it explores Jezero Crater.
Throughout the flight – designed to check the helicopter’s capacity to function an aerial scout – Ingenuity soared over a dune area nicknamed “Séítah.” Perseverance is making a detour south round these dunes, which might be too dangerous for the six-wheeled rover to strive crossing.
The colour pictures from Ingenuity, taken from a top of round 33 ft (10 meters), supply the rover workforce a lot higher element than they get from the orbiter pictures (such because the one above) they sometimes use for route planning. Whereas a digicam like HiRISE (the Excessive Decision Imaging Science Experiment) aboard NASA’s Mars Reconnaissance Orbiter can resolve rocks about 3 ft (1 meter) in diameter, missions often depend on rover pictures to see smaller rocks or terrain options.
“As soon as a rover will get shut sufficient to a location, we get ground-scale pictures that we are able to examine to orbital pictures,” stated Perseverance Deputy Challenge Scientist Ken Williford of NASA’s Jet Propulsion Laboratory in Southern California. “With Ingenuity, we now have this intermediate-scale imagery that properly fills the hole in decision.”
Under are a couple of of Ingenuity’s pictures, which accomplished the lengthy journey again to Earth on July 8.
Ingenuity (its shadow is seen on the backside of this picture) supplied a high-resolution glimpse of rock options nicknamed “Raised Ridges.” They belong to a fracture system, which frequently function pathways for fluid to movement underground.
Right here in Jezero Crater, a lake existed billions of years in the past. Spying the ridges in pictures from Mars orbiters, scientists have puzzled whether or not water might need flowed by these fractures sooner or later, dissolving minerals that might assist feed historical microbial colonies. That will make them a primary location to search for indicators of historical life – and maybe to drill a pattern.
The samples Perseverance takes will finally be deposited on Mars for a future mission that will take them to Earth for in-depth evaluation.
“Our present plan is to go to Raised Ridges and examine it shut up,” Williford stated. “The helicopter’s pictures are by much better in decision than the orbital ones we have been utilizing. Finding out these will permit us to make sure that visiting these ridges is essential to the workforce.”
Sand dunes like those on this picture maintain rover drivers like JPL’s Olivier Toupet awake at evening: Knee- or waist-high, they may simply trigger the two-ton rover to get caught. After touchdown in February, Perseverance scientists requested whether or not it was attainable to make a beeline throughout this terrain; Toupet’s reply was a tough no.
“Sand is an enormous concern,” stated Toupet, who leads the workforce of mobility specialists that plans Perseverance’s drives. “If we drive downhill right into a dune, we may embed ourselves into it and never have the ability to get again out.”
Toupet can be the lead for Perseverance’s newly examined AutoNav function, which makes use of synthetic intelligence algorithms to drive the rover autonomously over higher distances than may very well be achieved in any other case. Whereas good at avoiding rocks and different hazards, AutoNav can’t detect sand, so human drivers nonetheless must outline “keep-out zones” round areas that might entrap the rover.
With out Ingenuity, seen in silhouette on the backside of this subsequent picture, Perseverance’s scientists would by no means get to see this part of Séítah so clearly: It’s too sandy for Perseverance to go to. The distinctive view presents sufficient element to examine these rocks and get a greater understanding of this space of Jezero Crater.
Because the rover works its method across the dune area, it could make what the workforce calls a “toe dip” into some scientifically compelling spots with fascinating bedrock. Whereas Toupet and his workforce wouldn’t try a toe dip right here, the current pictures from Ingenuity will permit them to plan potential toe-dip paths in different areas alongside the route of Perseverance’s first science marketing campaign.
“The helicopter is an especially precious asset for rover planning as a result of it gives high-resolution imagery of the terrain we need to drive by,” stated Toupet. “We will higher assess the dimensions of the dunes and the place bedrock is poking out. That’s nice data for us; it helps determine which areas could also be traversable by the rover and whether or not sure high-value science targets are reachable.”
Extra In regards to the Mission
A key goal for Perseverance’s mission on Mars is astrobiology, together with the seek for indicators of historical microbial life. The rover will characterize the planet’s geology and previous local weather, pave the way in which for human exploration of the Crimson Planet, and be the primary mission to gather and cache Martian rock and regolith (damaged rock and mud).
Subsequent NASA missions, in cooperation with ESA (European House Company), would ship spacecraft to Mars to gather these sealed samples from the floor and return them to Earth for in-depth evaluation.
The Mars 2020 Perseverance mission is a part of NASA’s Moon to Mars exploration strategy, which incorporates Artemis missions to the Moon that may assist put together for human exploration of the Crimson Planet.
