As part of the programme known as Mars Sample Return, a separate mission will be sent to land on Mars to pick up the tubes using a "fetch" rover. The ascent vehicle blasts the samples into Martian orbit where they are captured by an orbiter.
This orbiter will then deliver the sample containers to Earth, possibly by Follow Paul on Twitter. What will the rover do? How did it get to Mars? The rover was encapsulated within an aeroshell, consisting of a backshell and heatshield.

Mastcam-Z : An advanced camera system to help study surface minerals MEDA : A Spanish-built sensor suite to measure temperature, wind speed and direction, pressure, humidity and dust MOXIE : Experiment to demonstrate how astronauts might produce oxygen from Martian CO2 for breathing and fuel PIXL : Has an X-ray spectrometer to identify chemical elements and a camera that takes close-up images of rock and soil textures RIMFAX : A Norwegian-built ground-penetrating radar that will map geology beneath the surface at centimetre scales SHERLOC : Will use spectrometers, a laser and camera to hunt for organics and minerals that were altered by water SuperCam : Will examine rock and soil with a camera, laser and spectrometers to look for organic compounds.
When she was in high school in Maryland, she saw a documentary about the rovers. As Spirit stopped but the Opportunity mission went on, its human minders grew close.
The children of mission scientists would hear of Opportunity almost as if the rover were a distant cousin. Pairs of rover drivers would spend so much time together, they'd practically read each other's minds. A lot of life happens. Now, the team has six months to wrap up and archive the mission's data and otherwise wind down what for some has been a fixture of their lives for decades.
This global mosaic of Mars is centered on Valles Marineris, the solar system's largest canyon range. It extends 4, kilometers and is seven kilometers deep in some places.
While this may be the end for Opportunity, the study and exploration of Mars is far from over. The rover Curiosity is still chugging along, as are several Mars orbiters and the InSight lander. The European and Russian space agencies are readying their own Mars rover, recently named Rosalind Franklin after the pioneering x-ray crystallographer. And many alumni from Spirit and Opportunity are hard at work on the upcoming Mars rover , which will search for signs of past life and cache rock samples for future return to Earth.
In the meantime, Opportunity will stand as a monument to science for hundreds of thousands of years—and maybe even a site where future explorers pay tribute. Perhaps in coming decades, humans will touch down in Meridiani Planum, Opportunity's landing area. Some scientists and engineers, including Seibert, have formally suggested the region as a landing site for crewed Mars missions. All rights reserved.

But will they invade your privacy? An enhanced brain will permit Perseverance to figure out its path on Mars autonomously up to five times faster than Curiosity. Team members hope this will reduce the amount of planning time needed for navigation, allowing the new rover to cover more ground and accomplish more tasks. The drill will cut intact rock cores in the Jezero Crater, the site of a former lake, which could then be retrieved by future missions and returned to Earth for in-depth study.
MOXIE, an oxygen-generating instrument the size of a car battery, will demonstrate how future explorers could produce oxygen from the Martian atmosphere.
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
