A Mars rover due to launch next year has been named after pioneering scientist Rosalind Franklin, the unsung* hero of DNA* research.

The UK-built Mars Rosalind Franklin rover is a part of a joint European and Russian project, called ExoMars.

Astronaut Tim Peake announced the name, which was the winning suggestion in an international competition.

Major Peake, speaking in the ‘Mars Yard’ at Airbus Defence and Space at Stevenage, UK, called Dr Franklin “one of the great British scientists who unlocked the secrets of human life in terms of understanding DNA.”

Alice Bunn, international director of the UK Space Agency, said in a statement: “Rosalind Franklin is one of science’s most influential women, and her part in the discovery of the structure of DNA was truly groundbreaking.

“It’s fitting that the robot bearing her name will search for the building blocks of life on Mars, as she did so on Earth through her work on DNA.”

There were 36,000 entries in the European Space Agency (ESA) naming competition. It chose to commemorate* Dr Franklin for her work during the 1940s and ‘50s.

She captured structural images of substances such as viruses* and coal, as well as the biological compounds DNA and RNA*, which both carry genetic* information.

US scientist James Watson and UK scientist Francis Crick used Dr Franklin’s research without permission and with little credit when publishing their model of the structure of DNA in 1953.

The pair won the Nobel* prize in 1962 for their work on DNA.

In Dr Watson’s book “The Double Helix,” which shaped future research on DNA for decades, he was extremely negative about Dr Franklin. She died in 1958 at age 37, and her work went mostly unacknowledged* until the 1990s.

“This name reminds us that it is in the human genes to explore,” ESA Director General Jan Woerner said.

“Science is in our DNA, and in everything we do at ESA. Rosalind (Franklin) the rover captures this spirit and carries us all to the forefront of space exploration.”

ROSALIND FRANKLIN MARS ROVER
The rover will launch in 2020 and is expected to reach Mars by 2021.

It will be the first to be able to roam around Mars and dig beneath the surface.

ESA astronaut Tim Peake, who is a former International Space Station crew member, said: “This rover will scout the Martian surface equipped with next-generation instruments — a fully-fledged automated laboratory on Mars.”

ROSALIND FRANKLIN
Dr Franklin was a chemist and an X-ray crystallographer. A chemist is a scientist who studies the structure of substances — how they are built from tiny building blocks called molecules and atoms — and how they react with each other. An x-ray crystallographer bounces X-rays off atoms and molecules to make an image to show how they are built.

Dr Franklin and another scientist, Raymond Gosling, captured an X-ray image of DNA in 1952. Their image led to the understanding of the shape of DNA.

After finishing her work on DNA, Dr Franklin led pioneering work on the molecular structures of viruses. Her team member Aaron Klug continued her research after Dr Franklin’s death and won the Nobel prize in Chemistry in 1982.
