Huge tracts of ice could lie under equatorial regions of Mars, scientists said on Thursday, challenging current understanding of the planet.
New radar data shows that the entire planet would be engulfed in water if the ice deposits melted, the international team of US and European scientists said.
They re-examined the Medusae Fossae Formation (MFF) on the planet, using data from the Mars Express orbiter’s Marsis radar, and now believe there are major deposits of ice under the surface of the Red Planet.
“We’ve explored the MFF again … and found the deposits to be even thicker than we thought, up to 3.7km thick,” said lead author Thomas Watters of the Smithsonian Institution.
“Excitingly, the radar signals match what we’d expect to see from layered ice, and are similar to the signals we see from Mars’s polar caps, which we know to be very ice-rich.”
The deposits had been identified previously but it was not known what they were made from.
“This latest analysis challenges our understanding of the Medusae Fossae Formation, and raises as many questions as answers,” said Colin Wilson, European Space Agency project scientist for Mars Express.
The MFF consists of several wind-sculpted features measuring hundreds of kilometres across and several kilometres high.
If melted, the ice could cover the planet in a layer of water up to 2.7m deep, or enough to fill Earth’s Red Sea.
“How long ago did these ice deposits form, and what was Mars like at that time? If confirmed to be water ice, these massive deposits would change our understanding of Mars' climate history,” Mr Wilson said.
“Any reservoir of ancient water would be a fascinating target for human or robotic exploration.”
Mars Express data showed the MFF to be relatively transparent to radar and low in density, both characteristics of icy deposits.
The new results suggest layers of dust and ice, topped by a protective layer of dust or ash several hundred metres thick.
The extent and location of the icy deposits would also make them potentially very valuable for our future exploration of Mars.
“Unfortunately, these MFF deposits are covered by hundreds of metres of dust, making them inaccessible for at least the next few decades,” the team said.
“However, every bit of ice we find helps us build a better picture of where Mars’s water has flowed before, and where it can be found today.”
Missions to Mars will need to land near the planet’s equator, far from the ice-rich polar caps or high-latitude glaciers.
They will need water as a resource, so finding ice in the region opens up new dreams of exploration.

Why does a queen bee feast only on royal jelly?
Some facts about bees:
The queen bee eats only royal jelly, an extraordinary food created by worker bees so she lives much longer
The life cycle of a worker bee is from 40-60 days
A queen bee lives for 3-5 years
This allows her to lay millions of eggs and allows the continuity of the bee colony
About 20,000 honey bees and one queen populate each hive
Honey is packed with vital vitamins, minerals, enzymes, water and anti-oxidants.
Apart from honey, five other products are royal jelly, the special food bees feed their queen
Pollen is their protein source, a super food that is nutritious, rich in amino acids
Beewax is used to construct the combs. Due to its anti-fungal, anti-bacterial elements, it is used in skin treatments
Propolis, a resin-like material produced by bees is used to make hives. It has natural antibiotic qualities so works to sterilize hive, protects from disease, keeps their home free from germs. Also used to treat sores, infection, warts
Bee venom is used by bees to protect themselves. Has anti-inflammatory properties, sometimes used to relieve conditions such as rheumatoid arthritis, nerve and muscle pain
Honey, royal jelly, pollen have health enhancing qualities
The other three products are used for therapeutic purposes
Is beekeeping dangerous?
As long as you deal with bees gently, you will be safe, says Mohammed Al Najeh, who has worked with bees since he was a boy.
“The biggest mistake people make is they panic when they see a bee. They are small but smart creatures. If you move your hand quickly to hit the bees, this is an aggressive action and bees will defend themselves. They can sense the adrenalin in our body. But if we are calm, they are move away.”
