Along with carrying 10 very high-tech scientific instruments one made in Canada , Curiosity takes with it the hopes and dreams of scientists trying to make a giant leap in the understanding of Mars. But maybe, just maybe, there are signs that the planet could have supported microbial life, and Curiosity is decked out to try to find evidence of that.
When Spirit and Opportunity landed on Mars in , each carried with it five scientific instruments weighing a total of five kilograms.
Curiosity has 10 instruments weighing a total of 75 kilograms. We've got more accurate landing capabilities. We've got longer live systems on the surface with nuclear power and we have state-of-the-art instruments aboard," McCuistion said. The rover's new functions and new science tools means it must accommodate a larger turret at the end of the robot arm.
This turret has the coring drill and two science instruments, plus a color camera for close-up surface inspection and also "selfies" for engineering health checkups.
The new rover will gather 20 sealed samples of Martian rocks and soil. The samples will be set aside in a "cache" on Mars. The team is building new software to run the rover. The software will be updated with improvements throughout the mission. New Wheels for Perseverance Engineers redesigned the Mars Perseverance rover's wheels to be more robust due to the wear and tear the Curiosity rover wheels endured while driving over sharp, pointy rocks.
Perseverance's wheels are narrower than Curiosity's, but bigger in diameter and made of thicker aluminum. The combination of the larger instrument suite, new Sampling and Caching System, and modified wheels makes Perseverance heavier than its predecessor, Curiosity. The Mars Rovers: Curiosity.
The Short Answer:. Curiosity is a rover that was sent to Mars to determine if the Red Planet ever had the proper conditions for microbial life to survive. Meet the Mars Rovers.

From a fiery entry into the atmosphere, a supersonic parachute needed to deploy to slow the spacecraft.
NASA officials said the parachute would need to withstand 65, lbs. Under the parachute, MSL let go of the bottom of its heat shield so that it could get a radar fix on the surface and figure out its altitude. The parachute could only slow MSL to mph kph , far too fast for landing. To solve the problem, engineers designed the assembly to cut off the parachute, and use rockets for the final part of the landing sequence.
About 60 feet 18 m above the surface, MSL's "skycrane" deployed. The landing assembly dangled the rover below the rockets using a foot 6 m tether.
Falling at 1. NASA personnel tensely watched the rover's descent on live television. When they received confirmation that Curiosity was safe, engineers pumped fists and jumped up and down in jubilation. News of the landing spread through traditional outlets, such as newspapers and television, as well as social media, such as Twitter and Facebook. One engineer became famous because of the Mohawk he sported on landing day. The rover has a few tools to search for habitability.
Among them is an experiment that bombards the surface with neutrons , which would slow down if they encountered hydrogen atoms: one of the elements of water. Curiosity's 7-foot arm can pick up samples from the surface and cook them inside the rover, sniffing the gases that come out of there and analyzing them for clues as to how the rocks and soil formed. The Sample Analysis of Mars instrument , if it does pick up evidence of organic material, can double-check that.
On Curiosity's front, under foil covers, are several ceramic blocks infused with artificial organic compounds. Curiosity can drill into each of these blocks and place a sample into its oven to measure its composition. Researchers will then see if organics appear that were not supposed to be in the block. If so, scientists will likely determine these are organisms hitchhiking from Earth. High-resolution cameras surrounding the rover take pictures as it moves, providing visual information that can be compared to environments on Earth.
This was used when Curiosity found evidence of a streambed , for example. In September , Curiosity arrived at its science destination, Mount Sharp Aeolis Mons shortly after a NASA science review said the rover should do less driving and more searching for habitable destinations.
It is now carefully evaluating the layers on the slope as it moves uphill. The goal is to see how the climate of Mars changed from a wet past to the drier, acidic conditions of today. Curiosity's prime mission is to determine if Mars is, or was, suitable for life.
