The northern hemisphere of Mars is beginning to thaw from winter. But for the red planet, that doesn’t mean that birds will sing and flowers will bloom. It means that the carbon dioxide will sublimate. It’s still beautiful though.

Who has an even bigger grin than ten years ago? This goofy-looking crater on Mars.

Like Earth, Mars has experienced periods of extreme glaciation or ice sheet coverage, which are known as ice ages. As these ice ages come and go, glaciers expand and contract along the planet’s surface, grinding huge boulders down to smaller rocks. By examining the size of boulders and rocks at specific locations on Mars, we should be able to understand the history of the Martian ice ages.
A new study did just that.

It’s looking more and more like the future of space exploration could involve drones in a big way.
We’ve already seen it here on Earth, where all kinds of flying drones are used by all kinds of people for all kinds of things. Drones are particularly useful in resource development, exploration, imaging, and remote sensing.
Could the future see drones flying around in the thin Martian atmosphere?

Many consider the various rovers we’ve sent to Mars as the next best thing to sending a geologist to the Red Planet. Spirit, Opportunity and Curiosity have carried all the necessary equipment similar to what human geologists use on Earth, and are able to navigate the terrain, “see” the landscape with the various cameras, pick up rock and dust samples with scoops, and then analyze them with various onboard tools and equipment.
In addition to all those things, the new Mars 2020 Perseverance rover will add a “sense of hearing” to its robotic toolkit. The rover includes a pair of microphones to let us hear – for the first time – what Mars really sounds like.

It’s always a sad day when a mission comes to an end. And it’s even sadder when the mission never really got going in the first place.
That’s where we’re at with NASA’s InSight lander. The entire mission isn’t over, but the so-called Mole, the instrument designed and built by Germany’s DLR, has been pronounced dead.

Since the 1960s and 70s, scientists have come to view Mars as something of a “dead planet.” As the first close-up images from orbit and the surface came in, previous speculation about canals, water, and a Martian civilization were dispelled. Subsequent studies also revealed that the geological activity that created features like the Tharsis Mons region (especially Olympus Mons) and Valles Marineris had ceased long ago.
However, in the past few decades, robotic missions have found ample evidence that Mars is still an active place. A recent indication was an image taken by the Mars Reconnaissance Orbiter (MRO), which showed relatively fresh landslides in a crater near Nili Fossae. This area is part of the Syrtis Major region and is located just north of the Jezero Crater (where the Perseverance rover will be landing in six weeks!)

If humans plan to go to live and work beyond Earth someday, they will need technologies that allow for sustainable living in alien environments. This is especially true of Mars, which is extremely cold, dry, and subject to more radiation than we are used to. On top of that, it also takes six to nine months to send spacecraft there, and that’s every two years when Earth and Mars are closest to each other in their orbits.
As such, settling on the Red Planet will require some serious creativity!
This is the purpose of Mars City Design (the Mars City®), an innovation and design platform founded by architect and filmmaker Vera Mulyani. Every year since its inception, this organization has hosted the Mars City Design Challenges, where students from around the world come together with industry experts to produce architectural designs for living on Mars (what Mulyani calls “Marchitecture”).

This past summer, NASA’s Perseverance rover launched from Cape Canaveral, Florida. On February 18th, 2021, it will arrive on Mars and join in the search for evidence for past (and maybe even present) life. A particularly exciting aspect of this mission is the Mars Sample Return (MSR), a multi-mission effort that will send samples of Mars back to Earth for analysis.
This aspect of the Perseverance mission will be assisted by a lander and orbiter developed by NASA and the European Space Agency (ESA). According to NASA, the MSR recently advanced to the next stage of development (Phase A). If all goes well, Perseverance will have a companion in the coming years that will take its samples and launch them to orbit, where they will be picked up and sent back to Earth.

In many ways, Mars is the planet that is most similar to the Earth. The red world has polar ice caps, a nearly 24-hour rotation period (about 24 hours and 37 minutes), mountains, plains, dust storms, volcanoes, a population of robots, many of which are old and no longer work, and even a Grand Canyon of sorts. The ‘Grand Canyon’ on Mars is actually far grander than any Arizonan gorge. Valles Marineris dwarfs the Grand Canyon of the southwestern US, spanning 4,000 km in length (the distance between LA and New York City), and dives 7 kilometers into the Martian crust (compared to a measly 2km of depth seen in the Grand Canyon). Newly released photos from the High-Resolution Imaging Science Experiment (HiRISE) aboard the Mars Reconnaissance Orbiter (MRO) reveal a stunning look at eroding cliff faces in Candor Chasma, a gigantic canyon that comprises a portion of the Valles Marineris system.
