Thanks to Curiosity, scientists now know much more about the planet. But it can also point to geological processes. In , however, the team determined the methane spike was not a seasonal event. There are smaller background changes in methane, however, that could be linked to the seasons.
Curiosity also made the first definitive identification of organics on Mars, as announced in December Organics are considered life's building blocks, but do not necessarily point to the existence of life as they can also be created through chemical reactions.
Initial results released at the Lunar and Planetary Science conference in showed scientists found complex organic molecules in Martian samples stored inside the Curiosity rover, but using an unexpected method.
In , results based on Curiosity's work added more evidence that life was possible on Mars. One study described the discovery of more organic molecules in 3.
The seasonal changes could mean that the gas is produced from living organisms, but there's no definitive proof of that yet. Besides hunting for habitability, Curiosity has other instruments on board that are designed to learn more about the environment surrounding it.
Among those goals is to have a continuous record of weather and radiation observations to determine how suitable the site would be for an eventual human mission. Curiosity's Radiation Assessment Detector runs for 15 minutes every hour to measure a swath of radiation on the ground and in the atmosphere. Scientists in particular are interested in measuring "secondary rays" or radiation that can generate lower-energy particles after it hits the gas molecules in the atmosphere.
Gamma-rays or neutrons generated by this process can cause a risk to humans. Additionally, an ultraviolet sensor stuck on Curiosity's deck tracks radiation continuously. A mission with days flying to Mars, days on the surface and days heading back to Earth would create a dose of 1. The total lifetime limit for European Space Agency astronauts is 1 sievert, which is associated with a 5-percent increase in fatal cancer risk over a person's lifetime.
The Rover Environmental Monitoring Station measures the wind's speed and chart its direction, as well as determining temperature and humidity in the surrounding air. By , scientists were able to see long-term trends in atmospheric pressure and air humidity. Some of these changes occur when the winter carbon-dioxide polar caps melt in the spring, dumping huge amounts of moisture into the air.
In early , Curiosity sent back pictures of crystals that could have formed from ancient lakes on Mars. There are multiple hypotheses for these features, but one possibility is they formed after salts concentrated in an evaporating water lake. Some Internet rumors speculated the features were actually signs of burrowing life , but NASA quickly discounted that hypothesis based on their linear angles — a feature that is very similar to crystalline growth.
Vapors from a "wet chemistry" experiment filled with a fluid called MTBSTFA N-methyl-N-tert-butyldimethylsilyl-trifluoroacetamide contaminated a gas-sniffing analysis instrument shortly after Curiosity landed. Since the scientists knew the collected samples were already reacting with the vapor, they eventually derived a way to seek and preserve the organics after extracting, collecting and analyzing the vapor.
Curiosity had a dangerous computer glitch just six months after landing that put the rover within only an hour of losing contact with Earth forever, NASA revealed in In some sense, the rover parts are similar to what any living creature would need to keep it "alive" and able to explore.
The Perseverance Rover Has The Following Parts: body : a structure that protects the rover's "vital organs" brains : computers to process information temperature controls: internal heaters, a layer of insulation, and more "neck and head": a mast for the cameras to give the rover a human-scale view eyes and ears : cameras and instruments that give the rover information about its environment arm and "hand" : a way to extend its reach and collect rock samples for study wheels and legs : parts for mobility electrical power : batteries and power communications : antennas for "speaking" and "listening".

The foreground shows a cliff on Mars; while in the sky, one can see both Venus and Earth appearing like stars in the dusty evening sky. In the summer of , Curiosity's science team began driving the rover toward a new and higher region on Mount Sharp where it will explore rocks rich in sulphate minerals. Because Mount Sharp was formed as layers of sediment were deposited by water and wind, the rocks get younger with height.
The sulphate minerals in this region may have formed because Mars went from wetter conditions—good for forming clay minerals—to drier conditions that could leave salts such as sulphates behind. On Sol , Curiosity completed its steepest drive of the mission as it ascended the sandy slope below the Greenheugh pediment, a broad flat surface capped by a sandstone layer.
The rover took these images on Sol as it looked across the layered sandstones and back over the Glen Torridon region below. We all know Mars as the Red Planet, we see that in the night sky.
However, as our drill tailings gallery shows, once we drill just a small depth in to the interior, Mars can be very different. We have drilled successfully 29 times now and the sediments show a range of hues from ochre-red to blue-grey reflecting the minerals and fluids that passed through the ancient rocks. Drilling allows us to get through the top most, oxidized surface that has been most exposed to cosmic radiation.
Curiosity in isolation at Glasgow. Each of the pixels is about 25cm, so we can pick out the rover quite nicely in the centre of the field of view. We had just completed a drill at a site we named Glasgow.
