Billion-year-old Martian dunes reveal planet’s history

The discovery of near-perfectly preserved billion-year-old Martian dunes is helping scientists to unravel the geologic and climatic history of the red planet. On October 5, 2020, a team of scientists announced the discovery of a group of one-billion-year-old Martian sand dunes in the planet’s Valles Marineris region. This rare find of paleo-dunes led scientists to a second big discovery. That is, climate, atmospheric pressure and landscape evolution on Mars have remained relatively consistent over the past billion years.

How to spot Mars during its closest approach in Tuesday’s night sky

If you want to see Mars, your best bet is to look at the night sky on Tuesday. The planet will be highly visible as its orbit makes its closest approach to Earth until 2035, according to NASA’s Mars Exploration Program. Mars will be easy to spot for most of the night, although it still will be about 38.6 million miles from Earth.

Mars Is Shining Bright This Month & Is Closer Than It Will Be for Almost 15 Years

Mars is not only the planet earthlings seem most obsessed with, it's one of the most beautiful objects in the night sky. It glows a ruddy red that stands out against the pale twinkling of stars around it. It's an alluring sight any time you get to see it, but October 2020 is an outstanding time to look at the red planet from your own backyard.

Water on Mars: discovery of three buried lakes intrigues scientists

Researchers have detected a group of lakes hidden under the red planet’s icy surface. Two years ago, planetary scientists reported the discovery of a large saltwater lake under the ice at Mars’s south pole, a finding that was met with excitement and some scepticism. Now, researchers have confirmed the presence of that lake — and found three more.

The colorful walls of an exposed impact crater on Mars

Impact craters have been called the "poor geologists' drill," since they allow scientists to look beneath to the subsurface of a planet without actually digging down. It's estimated that Mars has over 600,000 craters, so there's plenty of opportunity to peer into the red planet's strata—especially with the incredible HiRISE (High Resolution Imaging Science Experiment) camera aboard the Mars Reconnaissance Orbiter, which has been orbiting and studying Mars from above since 2006.

AI Is Helping Scientists Discover Fresh Craters on Mars

It's the first time machine learning has been used to find previously unknown craters on the Red Planet. Sometime between March 2010 and May 2012, a meteor streaked across the Martian sky and broke into pieces, slamming into the planet's surface. The resulting craters were relatively small - just 13 feet (4 meters) in diameter. The smaller the features, the more difficult they are to spot using Mars orbiters. But in this case - and for the first time - scientists spotted them with a little extra help: artificial intelligence (AI).

The way forward to Mars

The path that ExoMars 2022 will follow to reach the Red Planet is set. The trajectory that will take the spacecraft from Earth to Mars in 264 days foresees a touchdown on the martian surface on 10 June 2023, at around 17:30 CEST (15:30 UTC). The weather at Mars, the...

Can We Still Go to Mars?

Elsewhere in the solar system, a NASA rover is on its way to Mars. It carries, among other things, several pieces of spacesuit material. Designers want to see how the samples fare in the planet’s dusty, radiation-laden environment—the sturdy fabrics of the suit’s exterior, the cut-resistant fibers of its gloves, the shatterproof plastic of the bubble helmet that might someday reflect the soft light of a Martian sunset. When future astronauts arrive on the surface, the spacesuit designers back on Earth must be sure that they’re appropriately dressed for the occasion.
