How many chances of NASA to get on Mars – BBC News


Mars to find signs that once lived on Mars could be easier to find.

That is the scientists who manage NASA's mission without having to use it; It needs to be reached on its red planet in 2021 with the unique aim of being able to; trying to get evidence of past life.

The six-wheeled carriage that travels around Mars will Finding tracks on rocks that can be around 3.9 billion years old.

There was evidence that life on Earth at a very remote time was very difficult but researchers believe that the evidence could be better preserved on Mars.

This is the result of the dynamic modes in which; Our planet that shakes and flows out; recycle the rocks constantly, which may break the animals, but not stop in the & # 39; red planet at an early stage.

"We do not believe, for example, that Mars has a tectonic plates like Earth for most of its history," said Ken Williford of Labord Jet Jet, in California ( JPL). acronyms in English).

"Most of the Earth's rock recordings were destroyed by displaying under the shadow of the sea, but even the rock that rests on the surface is heated and damaged in ways that should not happen on Mars. So, on average, it is likely that the oldest rocks on Mars will be preserved better than young rocks on Earth, "he told BBC News.

Waterway and life

The research vehicle will carry out its work near Jezero's skin, which is a praising the soldiers once a suggestion & # 39; there was a deep lake.

Scientists hope if the microbes live in or around that water, their presence signs are preserved in sediments that are now easy to contaminate.

The main target of carbonate deposits is likely to be in line with the old loch shore.

"It's a kind of mineral in carbonates that flows out of the water and it's great about that when they catch everything in the water. Then, all life can be found inside the meal, "explained Briony Horgan from the University of Purdue in Indiana.

The situation is very good for her & her; Vehicle meets creatures that are similar to stromatolites. These are carbonate-shaped carbonate structures that are Earth-made with micro-bitumen rugs.

The vehicle chooses the most beautiful place on the coastal shore type and drill samples that can be packed in a vessel and abandoned on the ground to be collected later.

NASA and its European group, ESA, have a & # 39; Project project related to up to 40 samples of the vehicle back, possibly at the beginning of the 2030s.
