NASA Mars mission: Perseverance to begin search for life on Red Planet – Daily Express

The Perseverance rover has been on the planet for ten days - while the project is into its 213th day in total. Stunning images from the vehicle's 23 cameras captured the historic descent and dusty terrain of its landing - on what is thought to be a former lake.

Microphones picked up the sound of a gentle wind which was recorded and sent back to Earth.

Perseverance will spend at least two years drilling into rocks in the vicinity in search of past life.

Sanjeev Gupta, one of the leading scientists on the 3 billion mission, has said sophisticated laboratory analysis of samples will be used to establish if life existed.

He refers to the Jezero Crater on which the mission landed as Lake Jezero.

Discussing images of the Mars surface, he told BBC Newsnight: Youre looking at a new vista that nobody has ever seen before.

It looks like a very desolate place; reddish colour, rocks strewn.

But about 3.7 billion years ago, we think the crater that Perseverance landed in was actually a lake, so you would have been sitting in the middle of a lake.

The goals over the next year or so are going to be looking at the rocks we can see in the foreground and the background and trying to work out if the environment was actually habitable for life.

The project is so complex that gathered samples will not be returned until the 2030s, and hundreds of the worlds top scientists are offering their wisdom to the investigation.

"Thats what we are seeking - chemical evidence for life or fossilized signatures.

The tubes of samples we are going to bring back are going to be tiny.

"But with lab techniques on Earth we will be able to delve into detail on those.

Presenter Emily Maitlis asked Professor Gupta, of Imperial College Londons Department of Earth Science and Engineering, if life had to be an organism relying on oxygen or water - or whether a different definition could exist.

He replied: We use Earth examples.

The rocks we are looking at are 3.7 billion years old and the earliest life on Earth that we can be certain of occurred about 3.5 billion years ago - and thats microbial life in rocks in Australia that used water and chemical energy.

"So we are using the same sorts of learnings from Earth to look for life on Mars.

On the refinement and evolution of Earth as a planet, Prof Gupta added: It makes Earth feel very special, a tropical landscape on Earth feels very special, and one can actually imagine 3.7 billion years ago one could have actually had a picnic on the lake shore of Lake Jezero but thats not possible now.
