Nothing says springtime on Mars like defrosting dunes.

Here are the 7 Best Places to Search for Life in the Solar System

If humanity is ever going to find life on another planet in the solar system, it’s probably best to know where to look. Plenty of scientists have spent many, many hours pondering precisely that question, and plenty have come up with justifications for backing a particular place in the solar system as the most likely to hold the potential for harboring life as we know it. Thanks to a team led by Dimitra Atri of NYU Abu Dhabi, we now have a methodology by which to rank them.

Strange Terraces on Mars are a Clear Signal of Sedimentary Rock

If we’ve learned anything about Mars the past 2-3 decades from the various rovers, landers and orbiters we’ve sent to the Red Planet, it’s that the planet’s geologic history is much more complicated and diverse than what we thought.

This picture from the HiRISE (High Resolution Imaging Science Experiment) camera on the Mars Reconnaissance Orbiter shows fractured sedimentary rock inside a crater called Danielson. Sedimentary rock is a sure sign that this planet was active in the past. The fracturing, layering and terrace-like structures suggests a long-term watery history in this region.

Future Mars Explorers Could be Farming Oxygen From Landscapes Like This

Viking’s biochemistry experiments have been among the most hotly debated scientific results of all time. The lander famously collected samples from the Red Planet in 1976, in an experiment called “Label Release.” Scientists watched with bated breath as oxygen was released from the sample after it was subjected to a liquid slurry. They were then left scratching their heads as that oxygen production continued after the sample was sterilized via 160 degree C heat. Scientists now really agree that the oxygen production that Viking noticed was an abiotic process. But that also leads to a potential opportunity as some scientists think we can make oxygen farms out of a system similar to that used on Viking itself.

There’s a Big Rock Stuck Inside one of Perseverance’s Wheels

It looks like the Perseverance rover has an unwanted passenger, a rock stuck inside one of its wheels. The image of the stone was selected as the “Image of the Week” for Week 54 (Feb. 20 – 26, 2022) for the Perseverance mission. The Image of the Week is selected by public input. Perseverance captured this image on February 25th, 2022.

Mars Explorers are Going to Need air, and Lots of it. Here’s a Technology That Might Help Them Breath Easy

In situ resource utilization (ISRU) is still a very early science. Therefore, the technology utilized in it could be improved upon. One such technology that created one of the most useful materials for ISRU (oxygen) is MOXIE – the Mars OXygen In-situ Resource Utilization Experiment. A small-scale model of a MOXIE was recently tested on the Perseverance last year. Its primary goal is to create oxygen out of the Martian atmosphere.

A Mars Meteorite Shows Evidence of a Massive Impact Billions of Years ago

This artist’s impression shows how Mars may have looked about four billion years ago. The young planet Mars would have had enough water to cover its entire surface in a liquid layer about 140 metres deep, but it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 kilometres.

Researchers at Australia’s Curtin University have discovered evidence of a massive impact on the Martian surface after 4.45 billion years ago. This may not seem like a surprising revelation – after all, we know that there were several large impacts on Mars, like Hellas and Argyre, and we know that large impacts happened frequently in the early solar system – so why is this a big deal?

Curiosity Finds a Bizarre Rock on Mars that Looks Like a Flower

The Curiosity rover took a picture of something pretty enticing this week on the surface of Mars. While the object in question looks like a tiny little flower or maybe even some type of organic feature, the rover team confirmed this object is a mineral formation, with delicate structures that formed by mineral precipitating from water. The size of this tiny object is just 1 centimeter.

Here’s What China is Planning to do in Space for the Next 5 Years

Central planning is literately central to any communist country, though its history has mixed results. As part of that planning, bureaucrats in all parts of the government are occasionally tasked with coming up with goals and milestones for their specific part of the government. These usually take the form of a five or ten-year plan, which is what the China National Space Agency (CNSA) released on January 28th.

China Releases a Selfie-Stick Video of Tianwen-1 Above Mars

Selfies have become ubiquitous everywhere – even Mars. Now, the Tianwen 1 orbiter is getting into the spirit with a selfie taken high up in Martian orbit.
