Proper now, NASA’s Perseverance Rover is exploring the Jezero Crater on Mars. On Earth, Perseverance’s twin, OPTIMISM, is exploring the Mars Yard at NASA’s Jet Propulsion Laboratory (JPL) in Southern California.
OPTIMISM is a full-scale engineering mannequin of Perseverance, modified barely to raised deal with Earth’s situations. For instance, OPTIMISM has wider wheels than Perseverance does, to assist it higher fight Earth’s stronger gravity. OPTIMISM is brief for Operational Perseverance Twin for Integration of Mechanisms and Devices Despatched to Mars.
With OPTIMISM, NASA is ready to take a look at tough terrains and delicate pattern gathering on Earth. NASA can shortly intervene if one thing goes flawed, earlier than it has Perseverance tackle the duty.
OPTIMISM has not too long ago been given an improve. NASA scientists added further mobility software program and an adaptive caching meeting. Now, OPTIMISM is ready to do end-to-end testing, from drilling rock to accumulating samples to caching the samples in a cylinder.
The Mars Yard is so long as a doubles tennis court docket and twice as huge. It’s modeled to seem like a martian panorama. It’s a form of impediment course for NASA’s rovers, with slopes and rocks strewn about to check the rover’s mobility.

Perseverance is on Mars to seek for indicators of historical microbial life. That implies that it’s tasked with taking rock samples from Mars. OPTIMISM is testing a wide range of various kinds of rocks, because the scientists aren’t certain what Perseverance will encounter on Mars. For instance, OPTIMISM not too long ago cored a rock efficiently on a slope with out slipping. This makes scientists hopeful that Perseverance might do the identical on Mars.
OPTIMISM can be placing Perseverance’s autonomous navigation system, AutoNav, to the take a look at. Within the Mars Yard, the rover might be offered with obstacles for it to determine the best way to work round. The aim is to see if Perseverance can be prepared for longer drives sooner or later.
“The scale and form of rocks within the visible subject – will they flip into obstacles or not?” mentioned Bryan Martin, the flight software program and take a look at beds supervisor at JPL. “We take a look at a number of that and determine what sorts of issues to keep away from. What we’ve got safely traversed round right here has knowledgeable rover drivers in planning their traverses on Mars. We’ve completed a lot testing on the bottom we might be assured in it. It really works.”
The Perseverance Mars Rover was launched in July of 2020 and made its touchdown on Mars in February 2021. Perseverance is exploring the Jezero crater. In September 2021, the rover cored its first rock pattern on Mars.
