Mars's distinctive red rust may have been formed by water in the planet's ancient past, scientists believe.
Geologists say the dusty red surface that inspired astronomers to name the planet after a Roman god of war was covered in water billions of years ago. They believe they have found a substance with a "watery signature" that explains Mars's dramatic colour.
Scientists "were trying to create a replica Martian dust in the laboratory using different types of iron oxide," explained Adomas Valantinas, a planetary geologist at Brown University in the US. The one they found to be the "best fit" is known as ferrihydrite, a chemical compound containing iron and water.
The substance is found in volcanic areas on Earth but on Mars it "could only have formed when water was still present on the surface", Mr Valantinas said, suggesting Mars rusted earlier than had previously been thought. "Mars is still the Red Planet," he said. "It’s just that our understanding of why Mars is red has been transformed."
Scientists have long known that rusting iron is the key to Mars's colour, with winds believed to have spread the dust across the planet's surface after it was broken down over billions of years. However, the absence of water today led to suggestions that a dry compound, such as hematite, must have been responsible.
Question of life
But scientists have pointed the finger at ferrihydrite after grinding it down to a 100th of the size of human hair to replicate fine Martian dust, and using observations from spacecraft and "novel laboratory techniques", according to the European Space Agency.
It said the exact chemistry of Martian rust has been "intensely debated", because it provides a window into the planet's history and is "closely linked" to the question of whether Mars has ever been habitable.
"We eagerly await the results from upcoming missions like ESA’s Rosalind Franklin rover and the NASA-ESA Mars Sample Return, which will allow us to probe deeper into what makes Mars red," said Colin Wilson, a project scientist at the agency. He said samples of Martian dust had already been collecting and were awaiting return to Earth.
"Once we get these precious samples into the lab, we’ll be able to measure exactly how much ferrihydrite the dust contains, and what this means for our understanding of the history of water – and the possibility for life – on Mars," he said.

Key findings of Jenkins report
- Founder of the Muslim Brotherhood, Hassan al Banna, "accepted the political utility of violence"
- Views of key Muslim Brotherhood ideologue, Sayyid Qutb, have “consistently been understood” as permitting “the use of extreme violence in the pursuit of the perfect Islamic society” and “never been institutionally disowned” by the movement.
- Muslim Brotherhood at all levels has repeatedly defended Hamas attacks against Israel, including the use of suicide bombers and the killing of civilians.
- Laying out the report in the House of Commons, David Cameron told MPs: "The main findings of the review support the conclusion that membership of, association with, or influence by the Muslim Brotherhood should be considered as a possible indicator of extremism."

Tips for job-seekers
- Do not submit your application through the Easy Apply button on LinkedIn. Employers receive between 600 and 800 replies for each job advert on the platform. If you are the right fit for a job, connect to a relevant person in the company on LinkedIn and send them a direct message.
- Make sure you are an exact fit for the job advertised. If you are an HR manager with five years’ experience in retail and the job requires a similar candidate with five years’ experience in consumer, you should apply. But if you have no experience in HR, do not apply for the job.
