Deep analysis of the image captured on radar shows that the mars is coming out of an ice age due to ongoing climate change, said scientists on Thursday.

According to the research published in the journal Science Martian, ice began its retreat about 370,000 years ago, marking the end of the last ice age.

Using images taken by satellites orbiting Mars, the researchers determined that about 20,872 cubic miles (87,000 cubic km) of ice has accumulated at its poles since the end of the ice age, mostly in the northern polar cap.

Scientists are keenly interested in piecing together the climate history of Mars, which contains strong evidence that oceans and lakes once pooled on its surface, bolstering the prospects for life.

Scientists can now use the new ice measurements in computer simulations to more accurately model the Martian climate, said planetary scientist Isaac Smith of the Southwest Research Institute in Boulder, Colorado, who led the study.

“Previously those models were unconstrained by observations so they started with guesses. Now they have more to run on,” Smith said.

The study also was the first to tie a specific layer of Martian ice with a specific period of time. “Eventually we’d like to be able to do this for every layer,” Smith said.

From the perspective of an Earthling, every day on Mars may feel like an ice age. According to NASA, temperatures on Mars may hit a high at noon at the equator in the summer of roughly 70 degrees Fahrenheit (20 degrees Celsius), or a low of about minus-225 degrees Fahrenheit (minus-153 degrees Celsius) at the poles.

Unlike Earth, ice ages on Mars occur when its poles are warmer than average and frozen water is more stable at lower latitudes. Transitions between lengthy climate phases can leave telltale features in the ice, the research showed.

For example, Smith and colleagues found dramatic slopes in layers of ice within the Martian northern ice cap. Other layers reveal ice flowing in reverse direction. The climate cycles are triggered by changes in Mars’ orbit and tilt, which affect how much sunlight reaches the planet’s surface.

The climate changes on Red planet depend on the its orbit and tilt which also affects how much sunlight reaches the planet’s surface. For example, Smith and colleagues found dramatic slopes in layers of ice within the Martian northern ice cap. Other layers reveal ice flowing in reverse direction.

It is said that shifts on Mars are pretty strong as their tilt change is as much as 60 compared to that Earth’s tilt degree is just about 2 degrees. (Reuters)

    Just waiting for the day when scientists will declare Mars suitable enough for growth of living organisms. Hope one day we humans will travel to Mars.

NASA has launched a new interactive website that lets users explore how space technology impacts everyday life on Earth.

The new website, called NASA Home and City, features about 130 spinoff technologies in a virtual space, allowing users to tour through buildings and rooms to discover common items that NASA inspired or helped improve, the agency said in a statement on Tuesday.

These spinoffs are commercial products that apply NASA technology originally developed for studying and exploring space.

“Introducing NASA Home and City! A brand new interactive website where you can explore all the ways NASA benefits you in your daily life,” NASA Administrator Jim Bridenstine, said in a tweet.

“From GPS to airplanes, from baby formula to the camera in your phone, NASA technology is all around you!” he added.

The US agency’s collaboration with commercial companies has helped bring space technology back to Earth for over 50 years.

These range from water filtration systems, originally designed to purify water for the Apollo astronauts to durable wind turbines, designed with Mars in mind to the selfie taking camera, the report said.

“Our space technology continues to improve life on Earth,” said Jim Reuter, the acting associate administrator of NASA’s Space Technology Mission Directorate.

“NASA Home and City is a place of discovery for people, and especially students, who have ever wondered why space exploration should matter to them,” Reuter noted. (IANS)
