One of the major tasks assigned to the robotic Curiosity of NASA is to search for the presence of ancient life on Mars.

It has been there on the Red Planet since August 6, 2012, busy investigating the Martian climate and geology. It wants to unearth evidence on whether the Gale Crater supported life forms in the past. The rover has already discovered traces of certain molecules that could be possible positive signs. Thanks to the Renewable Energy available on Mars in solar power, the NASA robot has been active throughout its stay on the alien surface.

Daily Mail UK says the latest findings are results of a new technique NASA used in 2017. It happened when the rover's drill stopped functioning. Ground control evolved an alternate procedure to collect samples. At that time, the dirt revealed the presence of benzoic acid and ammonia. These occur naturally in plants and animals, including humans. An expert says these molecules are not biosignatures. They are not evidence of past or present life. However, they reveal the presence of biosignatures. The expert is Maëva Millan, a postdoctoral fellow at NASA's Goddard Spaceflight Center. Curiosity has been capturing images of Mars.

NASA used this new concept on Mars

The new concept used by NASA is a wet chemistry experiment.

Europe's upcoming Rosalind Franklin Mars rover could rely on the same logic for its rover. It is set to launch in September 2022. Its schedule was last summer, but the launch suffered delays due to coronavirus restrictions.

Daily Mail UK reports it will be similar to the Perseverance rover of NASA, which launched in July 2020.

The rover Rosalind Franklin will also join the search for signs of ancient life on Mars. It is equipped with a unique drill that can go down to a depth of six and a half feet below the Martian surface to extract samples for analysis. NASA's Mars science rover Perseverance has collected samples of Martian rock. Obviously, the composition of the samples would be different because their sources would not be the same.

The world is curious to learn more about Mars

Since H. G. Wells wrote the sci-fi novel "War of the Worlds" in the late 19th century, the world has been curious to learn more about Mars. Different countries are trying to explore the planet for various reasons. NASA has taken the lead and has positioned robots on the planet to keep track of happenings.

According to WION, NASA's Mars Curiosity rover is exploring the Red planet to provide evidence of any lifeforms. Its Curiosity rover mixed a sample of Martian dirt with chemical reagents inside a cup.

Researchers analyzed in March 2017. The result was a combination of organic molecules that were new on the surface of Mars. Zhurong, the rover of China, landed on Mars, and it has joined the American rover's Curiosity and Perseverance to study the planet.

Many eyes focused on Mars, the red planet

Apart from the United States and China, UAE is also in the race to put its footprint on Mars. Europe has its upcoming Rosalind Franklin Mars rover on the cards. Objectives vary from identifying helpful natural resources on the planet to its colonization and using it as a stepping-stone to other destinations.

WION adds organic molecules are the building blocks of life on Earth, and they might be found elsewhere in the cosmos as well. Curiosity rover has discovered traces of organic compounds buried in Martian sediments. Perseverance rover is also collecting samples from the surface of Mars for detailed study in a laboratory. Common to all countries is their knowledge of the three basics of working with Artificial Intelligence, robotics, and renewable energy when the subject is millions of miles away.
