Curiosity's design serves as the basis for the planned Mars 2020 rover, which will carry different scientific instruments. According to the space agency, Curiosity's selfie was stitched together using 57 images taken by the rover using the camera on its robotic arm. Just left of the rover are the two drill holes, called Glen Etive 1 (right) and Glen Etive 2 (left). There are individual cups inside the lab to test samples.
SAM then heats the samples, "sniffing" the gases that bake off, looking for chemicals that hold clues about the Martian environment billions of years ago. This solvent can eat through samples and help to detect organic compounds that are relevant to life development in so-called "wet chemistry" experiments.

Clay-based rocks are good at preserving chemical compounds, which break down over time.
NASA is intrigued to see which organic compounds, if any, have been preserved in the Red Planet's regolith.
Curiosity's SAM contains 74 cups that the rover uses to test samples. Each 20.7-inch (52.5 cm) wheel is a more advanced version of those installed on the Curiosity rover, which have suffered from an unexpected amount of wear and tear since landing on Mars in 2012.
They therefore sent the Ogunquit Beach sand to one of SAM's wet chemistry cups since there was still science to be gained. The rover drilled twice in this location, nicknamed Glen Etive.More news: Cyclone Kyarr To Bring Rain In Gujarat Before Heading To Oman
NASA built upon the Ogunquit Beach rehearsal to make adjustments to improve upon the 2016 experiment.
Scientists should know the results of the experiment next year. Mr Mahaffy added: 'SAM's data is extremely complex and takes time to interpret.
NASA's Curiosity rover took this selfie on October 11, 2019, the 2,553rd Martian day, or sol, of its mission. As an aside, the six wheels now on the Mars 2020 rover are placeholders, as the actual wheels for the mission won't be installed until next year. In addition to the rover, other notable regions such as the Gale Crater and the Vera Rubin Ridge can be spotted in the photo.
Curiosity has been ascending Mount Sharp, a three mile (5km) tall mountain inside the crater. A new NASA timelapse showcases the latest major milestone, as the rover can now support itself on its six legs and wheels.More news: Virgin Galactic to be 1st publicly traded firm next week
