In listless July, NASA launched Perseverance rover to Mars to hunt for indicators of former lifestyles on the Red Planet. As the robotic astrobiologist floats via position on its solution to Mars, its twin is getting prepared to reproduction the rover’s mission factual right here on Earth.Perseverance’s Earthly twin is gearing up to place apart out to the ‘Mars Yard’ this month, the place apart this would possibly possibly possibly possibly simulate the mission that Perseverance will rob in over 44 million miles away.Its title? OPTIMISM.Perseverance’s discontinuance to-equal twin is a plump-scale engineering version of the Mars rover, with six wheels, cameras, and a pc system that enables it to autonomously drive spherical the simulated Martian panorama. The down-to-Earth robotic counterpart is dubbed OPTIMISM, which stands for Operational Perseverance Twin for Integration of Mechanisms and Devices Despatched to Mars.”Perseverance’s mobility group can not wait to sooner or later drive our check rover open air,” Anais Zarifian, the mobility check mattress engineer at NASA’s Jet Propulsion Laboratory, acknowledged in a recent assertion. “Right here’s the check robotic that comes closest to simulating the true mission operations Perseverance will experience on Mars – with wheels, eyes, and brains all collectively – so this rover is going to be specifically fun to work with.”OPTIMISM passed its first driving check on September 1, and the group of engineers hope to birth up check-driving it subsequent week within the Mars Yard. The Mars Yard is a simulated Martian panorama, total with crimson grime, rocks, and other obstacles that the Perseverance rover would possibly possibly possibly come right via whereas rolling spherical the Red Planet.In a formulation, Perseverance’s Earthly twin can even moreover be thought of as the “corrupt” twin to the Mars rover. The reason is that after Perseverance lands on Mars in February, 2021, the rover’s group ought to no longer in a situation to physically work on the auto-sized robotic. Which arrangement, is something goes nasty, any repair desires to be some distance-off — and factual. By creating an Earthly counterpart, the group can accumulate and repair any hardware or utility complications the rover will possess sooner than they open up transmitting instructions to the Mars machine. “The Mars 2020 Perseverance check mattress group’s motto is ‘No optimism allowed,'” Matt Stumbo, the lead for the OPTIMISM rover on the check mattress group, acknowledged in an announcement. “So we named the check rover OPTIMISM to remind us of the work we possess got to make to fully check the system. Our job is to build up complications, no longer factual hope actions will work. As we work via the factors with OPTIMISM, we cancel self assurance in Perseverance’s capabilities and self assurance in our capability to feature on Mars.”OPTIMISM passed its first driving check at a warehouse in Southern California whereas its twin hurls via position on its solution to Mars.NASA/JPLAs it stands nowadays, OPTIMISM has the identical mobility system and prime driving bustle (0.094 mph), as neatly as the identical robotic “head,” a some distance-off sensing mast, as Perseverance. Nevertheless a second building section on the starting of the unique one year will admire OPTIMISM bear the total science instruments, cameras, and computer brains of its Martian counterpart, too.Fancy every pair of twins, the 2 make possess some, tiny differences. OPTIMISM is linked to an umbilical cord of a form, a nuclear battery the place apart it will get its energy. The cord also connects OPTIMISM with the ground group who will most likely be sending it instructions, quite than having to send instructions via a network of antennas your total solution to Mars.Proper as Perseverance will rendezvous with its robotic counterpart Curiosity, which has been roaming spherical the Red Planet since 2012, OPTIMISM will work aspect-by-aspect with Curiosity’s possess Earth twin, MAGGIE (Mars Computerized Extensive Gizmo for Integrated Engineering). “The Curiosity mission has learned lessons from MAGGIE that possess been very no longer prone to learn any opposite path,” Stumbo acknowledged. “Now that we possess got OPTIMISM, the Perseverance mission is neatly equipped to learn what they possess to prevail on Mars.”The two pairs will most likely be tethered to every other, mirroring every other’s actions. With any luck, the Earth group would possibly possibly possibly no longer high-tail rogue.
