Perseverance rover collects water-altered rocks in search for ancient life on Mars

The mystery of possible life on Mars may one day be solved after the Nasa’s Perseverance rover collected the first rock samples from the red planet that could be returned to Earth for analysis.

The rover took samples from the floor of the Jezero crater, which 3.7 billion years ago was a lake fed from a small river.

Watery Mars could have supported life billions of years ago, say scientists.

The rocks analysed and stored for return to Earth have been altered by water.

“These kinds of environments on Earth are places where life thrives,” said University of Florida astrobiologist Amy Williams, one of the long-term planners for the Perseverance mission.

“The goal of exploring the Jezero delta and crater is to look in these once-habitable environments for rocks that might contain evidence of ancient life.”

The rover is now surveying the river delta to collect additional rock samples for the Mars Sample Return mission.

This is a proposed mission to return Martian rock and dust samples to Earth in a small rocket brought to the planet surface in a lander.

“When that delta was deposited is one of the main objectives of our sample return programme, because that will quantify when the lake was present and when the environmental conditions were present that could possibly have been amenable to life,” said geochemist David Shuster, professor of earth and planetary science at the University of California, Berkeley.

Perseverance landed at the bottom of the Jezero crater in February 2021.

Since then, scientists have been exploring the geological make-up of the crater floor using a suite of tools on board the rover.

The researchers discovered the crater floor had eroded more than they expected.

Erosion exposed a crater made up of rocks formed from lava and magma, known as igneous rocks.

Before the mission, geologists expected that the floor of the crater would be filled with either sediment or lava that had spilt on to the surface and cooled rapidly.

However, at two sites referred to as Seitah — the Navajo word for “amidst the sand” — the rocks appear to have formed underground and cooled slowly.

This suggests that whatever was covering them has eroded away over the past 2.5 to 3.5 billion years.

“We have organisms on Earth that live in very similar kinds of rocks,” said Dr Williams.

“The aqueous alteration of the minerals has the potential to record biosignatures.”

Nasa and the European Space Agency plan to return the rock samples to Earth around 2033 with the Mars Sample Return mission.

Because the rock samples taken at the bottom of the crater likely predate the river delta, dating these rocks will provide important information about the age of the lake.

The findings are published in the Science journal.

What you as a drone operator need to know

A permit and licence is required to fly a drone legally in Dubai.

Sanad Academy is the United Arab Emirate’s first RPA (Remotely Piloted Aircraft) training and certification specialists endorsed by the Dubai Civil Aviation authority.

It is responsible to train, test and certify drone operators and drones in UAE with DCAA Endorsement.

“We are teaching people how to fly in accordance with the laws of the UAE,” said Ahmad Al Hamadi, a trainer at Sanad.

“We can show how the aircraft work and how they are operated. They are relatively easy to use, but they need responsible pilots.

“Pilots have to be mature. They are given a map of where they can and can’t fly in the UAE and we make these points clear in the lectures we give.

“You cannot fly a drone without registration under any circumstances.”

Larger drones are harder to fly, and have a different response to location control. There are no brakes in the air, so the larger drones have more power.

The Sanad Academy has a designated area to fly off the Al Ain Road near Skydive Dubai to show pilots how to fly responsibly.

“As UAS technology becomes mainstream, it is important to build wider awareness on how to integrate it into commerce and our personal lives,” said Major General Abdulla Khalifa Al Marri, Commander-in-Chief, Dubai Police.

“Operators must undergo proper training and certification to ensure safety and compliance.

“Dubai’s airspace will undoubtedly experience increased traffic as UAS innovations become commonplace, the Forum allows commercial users to learn of best practice applications to implement UAS safely and legally, while benefitting a whole range of industries.”

Who is Tim-Berners Lee?

Sir Tim Berners-Lee was born in London in a household of mathematicians and computer scientists. Both his mother, Mary Lee, and father, Conway, were early computer scientists who worked on the Ferranti 1 - the world's first commercially-available, general purpose digital computer. Sir Tim studied Physics at the University of Oxford and held a series of roles developing code and building software before moving to Switzerland to work for Cern, the European Particle Physics laboratory. He developed the worldwide web code as a side project in 1989 as a global information-sharing system. After releasing the first web code in 1991, Cern made it open and free for all to use. Sir Tim now campaigns for initiatives to make sure the web remains open and accessible to all.
