Signs Of Life On Mars

On Feb. 18, NASA’s Perseverance rover landed on Mars to search for signs of life there.

Our most recent package previews the mission, drilling down into the scientific instruments that will be used to explore the planet’s atmosphere, dust, soil, rocks and weather. It also describes just how difficult a challenge it will be for Perseverance to collect and return Martian samples to Earth. See below for more.

With the arrival of the Perseverance rover on Mars, scientists kick off a series of missions to bring back samples from the Red Planet in a quest to answer the age-old question if life exists beyond Earth. The rover follows NASA's ongoing Mars Science Laboratory Curiosity mission to look for habitable environments and cache samples for return to Earth. NASA is partnering with the European Space Agency for the sample return project. Meanwhile, the international fleet of spacecraft operating around Mars now includes the United Arab Emirates' Hope and China's Tianwen-1 orbiters, which arrived on Feb. 9 and 10, respectively.

“We’re very optimistic to take the next step to look directly for signs of ancient life."
