Perseverance aims to travel quickly and efficiently, journeying at least 15 kilometres across Jezero in one Mars year which is nearly 2 years on Earth — the time NASA allotted for the initial mission. It carries 43 tubes for collecting Martian rock and dirt; the goal is to fill and lay down 15 to 20 of them by the end of that first year for future spacecraft to pick up.
Countdown to Mars: three daring missions take aim at the red planet. The plutonium-powered rover could then roll onto a neighbouring plain to explore other environments that were suitable for ancient life and continue collecting rocks and soil. The earliest any of its samples could be returned to Earth is It is the third mission to reach the red planet this month — following spacecraft from the United Arab Emirates and China , which are both now in orbit.

The whole of the landing was streamed live via NASA's YouTube channel, and the rover was later able to send back high definition footage from the final moments of its descent. From the deploying of the parachute to the final 'sky crane' assisted touchdown, check out the video of Perseverance landing on Mars below. You can track where the Perseverance rover is now using NASA's interactive rover map, which uses live data to plot Perseverance's journey around Jezero Crater.
Track the Perseverance rover. Just like Gale crater, the location for NASA's other current rover Curiosity, Jezero is the site of a suspected ancient lake and river delta. As water is an extremely important part of the existence of all known life on Earth, anywhere it could be found on Mars — whether in the modern day or in the ancient past — is a good place to be looking for evidence of life on the planet.
Just as geologists here on Earth would take samples of rocks from various places around a region to study them, Perseverance will take and analyse samples using a sophisticated 'chemistry set', the results of which are transmitted back to the scientists here on Earth.
All four science objectives for the Mars mission relate to searching for signs of life on Mars. The rover could even enable humans to live on Mars in the future: one of its instruments is designed to produce oxygen from the Martian atmosphere. Perseverance will search for signs of past and present life on Mars, as well as test out new technologies to aid future human missions to Mars. To complete these scientific goals, the rover has been fitted with several scientific instruments, each designed to perform different experiments or test new technology.
It will also carry samples of astronaut spacesuit material, testing to see whether they can withstand the harsh Martian environment. If oxygen can be extracted from the atmosphere, it could be used in future human missions to provide oxygen to astronauts and possibly be used in other technologies such as transport systems on the planet.
The rover will even include a small autonomous helicopter called Ingenuity. This is a technology demonstration which, if successful, could be used in future missions to scout out areas to explore on the surface of Mars. NASA's Perseverance rover, at 3 metres long and 2. Both Mars and the Earth orbit around our Sun, the Earth taking one Earth year to complete one trip, while Mars takes a little under 2.
Because of this the distance to Mars can be as little as 55 million kilometres when they are both in the same part of their orbits, or as far as million kilometres when they are on opposite side of the Sun. On average it's around million kilometres. The rover's mission is to collect samples of Martian rock and soil. These samples will be picked up by a future mission for detailed analysis on Earth, according to NASA.
However, Perseverance is not alone in this mission. It has a helicopter, Ingenuity , for aerial surveillance.
