Step Into ‘Winter Wonderland’ On Mars With These Stunning Pictures Taken By ESA’s Orbiter

Published

As the world gets into holiday mood, the European Space Agency (ESA) has shared pictures of ‘Winter Wonderland’ on Mars. The images feature the icy landscape on the red planet’s south pole captured by the Mars Express orbit.

The region in the pictures is named Australe Scopuli where the red landscape turns white due to swirls of carbon dioxide ice and dust layers. Temperature drops as low as -125°C when it snows in the southern polar region.

According to ESA, the images were taken in June 2022 close to summer solstice at the Martian south pole. Around this time, the region gets covered in dark patches as the ice sublimates i.e. turns directly from solid into vapour, when the sunlight warms the surface.

As the sunlight causes the sublimation, pressure builds in pockets of gas which makes the icy layer crack and bursts of gas jet outwards.

“These gas fountains carry dark dust from below, which falls back to the surface in a fan-shaped pattern moulded by the direction of the prevailing wind. The fans can range in length from tens to hundreds of metres,” ESA explained in a statement.

It further said that the fan-like structure normally forms boundaries between the polar layered deposits highlighting weak zones where ice cracks more easily.

Mars is also tilted on its axis like Earth meaning it has seasons similar to our planet. However, the seasons last twice as long because the planet takes two Earth years to orbit the Sun.

NASA Takes Instagram Followers By Surprise With Picture Of A Crane; ‘Is It Hacked?’

Published

By



NASA, on Thursday, surprised its Instagram followers by posting a picture of a Sandhill Crane. The image featured the crane looking dead straight into the camera with NASA‘s rocket assembling building visible as a blur in the background.

Deviating from the lines of astronomy, NASA chose to educate its followers about the bird which according to the agency is among the 1,500 species of animals and plants that reside at the Kennedy Space Center (KSC) in Florida.

The agency said that KSC, which shares space with the Merritt Island National Wildlife Refuge is a particularly favorable environment. The sandhill cranes get drawn to this region due to the region’s shallow freshwater habitats, which provide nesting space and a variety of food sources.

Also featuring in this picture is the Vehicle Assembly Building where NASA assembles its rockets including the Space Launch System (SLS) which launched Artemis 1 Moon mission in 2022.

The image shared by NASA took the followers by surprise who questioned ‘why the bird?’

“Has anyone hacked NASA’s page?” one user asked. “You’re a NASA page, why are you acting like the Nat Geo channel?” asked another.

Others just appreciated the bird staring into the camera with its big brown eyes and thanked NASA for the information.

U.S. satellites reveal China’s solar dominance

The sun‘s energy is plentiful. And China is capitalizing.

Images captured by two Earth-observing satellites, operated by the U.S. Geological Survey, revealed a rapid expansion of solar farms in a remote northern Chinese region, the Kubuqi Desert.

“The construction is part of China’s multiyear plan to build a ‘solar great wall’ designed to generate enough energy to power Beijing,” writes NASA‘s Earth Observatory. (For reference, although all this energy won’t directly power the Chinese capital, around 22 million people live in Beijing; that’s over two and a half times the population of New York City.)

The two Landsat satellite images below show a section of the major solar expansion between 2017 and 2024. Use the slider tool to reveal the changes. (For a size and scale reference, the images below are about 10 kilometers, or 6.2 miles, across.)

And the solar complex is still growing. It will be 250 miles long and 3 miles wide by 2030, according to NASA.

Though China’s energy mix is still dominated by fossil fuels — coal, oil, and gas comprised 87 percent of its energy supply as of 2022 — the nation clearly sees value in expanding renewable energy.

“As of June 2024, China led the world in operating solar farm capacity with 386,875 megawatts, representing about 51 percent of the global total, according to Global Energy Monitor’s Global Solar Power Tracker,” NASA explained. “The United States ranks second with 79,364 megawatts (11 percent), followed by India with 53,114 megawatts (7 percent).”

Energy experts say that solar energy, like wind, is an important part of an energy supply, as they’re renewable and have been shown to reduce energy costs. Fossil fuels, of course, still play a prominent role in most states’ energy mix today.

But the economics of solar are clearly there. The proof, via U.S. satellites, is in the Kubuqi Desert.
