‘Curiosity’ will not be NASA’s solely energetic Mars rover for for much longer as in subsequent summer season, ‘Mars 2020’ will probably be headed for the Pink Planet. Constructed and managed by NASA’s Jet Propulsion Laboratory in Pasadena, California, every has its personal function within the ongoing exploration of Mars and the seek for historical life. The Mission behind touchdown ‘Curiosity’ in 2004 was to “follow the water,” the dual rovers ‘Spirit’ and ‘Alternative’ found proof that the planet as soon as hosted operating water earlier than turning into a frozen desert, NASA stated in a press launch.
‘Mars 2020’s’ arm has the identical attain as ‘Curiosity’s’, however its turret weighing extra, 99 kilos (45 kilograms) as a result of it carries bigger devices and a bigger drill for coring. The drill will minimize intact rock cores, quite than pulverizing them, they usually’ll be positioned in pattern tubes by way of a fancy storage system.

“‘Mars 2020’s’ body, is about five inches longer than ‘Curiosity’. It’s also heavier, checking in at 2,260 pounds (1,025 kilograms), compared with Curiosity’s 1,982 pounds (899 kilograms). The weight difference has to do with the tools each carries,” the discharge acknowledged.
‘Mars 2020’ can even discover a panorama formed by water which is the ‘Jezero Crater’, the location of an historical delta. However 2020 will take the subsequent scientific step: It should search for precise indicators of previous life, or biosignatures, capturing samples of rocks and soil that might be retrieved by future missions and returned to Earth for in-depth examine.
Beginning with the robotic arms: Curiosity extends 7 ft (2.2 meters) and wields a rotating 65-pound (30-kilogram) turret geared up with a scientific digicam, chemical analyzer, and drill. The roving science lab pulverizes rock samples and pours the powder into its chassis, the place two laboratories can decide the rocks’ chemical and mineral make-up, stated NASA.
‘Mars 2020’ has 23 cameras, most of them are color cameras. The brand new rover additionally consists of ‘ears’, which might be two microphones to seize not solely the primary sounds of a Mars touchdown but additionally Martian wind and the rover’s chemical-analyzing laser zaps. ‘Mastcam-Z’, an improved model of Curiosity’s Mast Digital camera, has a zoom functionality and can take high-definition video and panoramas.
Whereas ‘Mars 2020’s’ wheels are produced from the identical supplies, as ‘Curiosity’s’ they’re barely larger and narrower, with skins which might be virtually a millimeter thicker. As a substitute of Curiosity’s chevron-pattern treads, or grousers, Mars 2020 has straighter ones and twice as many per wheel (48 versus 24). In depth testing in JPL’s Mars Yard has proven these treads higher face up to the stress from sharp rocks however work simply as properly on sand.
“Mars rovers don’t drive themselves. Teams of scientists and engineers beam meticulously programmed task lists to them at the beginning of each Mars day. Rover drivers on Earth then wait for the vehicle to report back before planning the next drive. The more a rover can do on its own, the more time drivers have to program new commands,” it acknowledged.
‘Mars 2020’ has much more self-driving smarts, permitting it to calculate a path 5 occasions sooner than Curiosity can. That self-driving will probably be key to condensing the period of time it takes for the 2020 staff to plan every day’s operations. The brand new mission intends to ultimately condense day by day operations to simply 5 hours.
‘Curiosity’ reworked Mars landings with the seemingly radical “sky crane maneuver.” Mars 2020 will depend on the identical course of but additionally options an vital new know-how: Terrain Relative Navigation. An onboard pc matches floor pictures from a digicam to a map to maintain the spacecraft on the right track. In the meantime, the Vary Set off lets the rover get miles nearer to a super web site earlier than firing a parachute.
‘Mars 2020’ will carry spacesuit samples, permitting scientists to review how they degrade. An oxygen generator will check know-how for astronauts to make their very own rocket gasoline from the Martian ambiance. Subsurface radar just like the one on the rover may sometime be used to search out buried water ice, the house company stated.
