![]() ![]() The plan for the Mars Sample Return mission involves a small rover called a Fetch Rover, one or more sample recovery helicopters, and the first rocket to take off from another planet. NASAs Mars rover Curiosity took 25 images in Gale Crater using its mast-mounted Right Navigation Camera (Navcam) to create this mosaic. That's the aim of NASA's Mars Sample Return mission, which plans to transport samples from Mars to Earth for further study in the 2030s. By looking at layers of rock, scientists can see different periods in Mars' history and learn about things like the climate or temperature during different time periods.īut if we want to really understand more about the history of Mars, and especially whether there was ever life there, we need to get samples off the planet and back to labs on Earth where they can be examined in more depth. It can perform investigations using instruments like spectrometers to understand the composition of rock samples, and it can use its cameras to image the areas those samples were taken from and see whether there are useful geographic features like layers that can give a clue to the area's past. "On Earth, preparing for sampling is a massive undertaking and involves careful coordination across all instrument teams, scientists, and engineers it’s a huge team effort," Dr Kronyak said.To understand the history of Mars, a rover like Perseverance is an important tool. To date, the rover has collected 19 of a.
