What would be the best method for exploring planetary atmospheres, such as at Mars, Venus or even Earth? One group of researchers are developing tiny, levitating “nanocardboard” aircraft that could hover in alien skies. They would fly like dust floating in beams of sunlight – but intelligently, and with a purpose.
“It’s exciting because it’s essentially a new mechanism of flight,” said Igor Bargatin from the University of Pennsylvania. “We’re talking about a structure half an inch in size that can fly around without any moving parts.”

It’s no secret that Mars once had abundant water flowing on its surface in the forms of rivers, lakes, and even an ocean. For this reason, scientists continue to wonder whether or not Mars might have had life in the past. Today, the surface is an extremely cold, dry place where even a single droplet of water would instantly freeze, boil, or evaporate. Unless, of course, the water had salt dissolved in it.
If these “briny” patches still exist on Mars, then it’s possible there are small pockets on the surface where microbes can still exist. This presents problems as far as issues of “planetary protection” are concerned. However, a new study led by the Lunar and Planetary Institute (LPI) has shown that if life from Earth were brought over by robotic or human explorers, it probably couldn’t survive in these brines.

The HiRISE (High-Resolution Imaging Science Experiment) instrument on NASA’s Mars Reconnaissance Orbiter (MRO) has given us a steady stream of images of the Martian surface. It’s been in orbit around Mars since March 2006, and has greatly outlived its intended mission length.
One of the latest Hi-PODs, or HiRISE Pictures of the Day, is this one, of sedimentary rock on Mars being eroded away.

A future rover on Mars may include shape-shifting capabilities. This innovative tech won’t quite be like the liquid-metal polymorphing robot from “Terminator 2,” but will solve a problem that have plagued previous rovers: wheel wear and tear.
NASA’s Glenn Research Center is now using shape memory alloys (SMA) to build better wheels for driving on Mars.

70 days from now, the next launch window to Mars opens. That’s when NASA will launch their Perseverance Rover. New images from NASA show the advanced rover being put into the fairing, readying it for its long journey.

Billions of years ago, Mars was once a much different place than the cold and desiccated place it is today. Basically, it had a thicker, warmer atmosphere and liquid water flowing on its surface, and maybe even life! The reason for this is because, like Earth, Mars had a planetary magnetic field that was generated by action in its core. But when that field disappeared, things began to change drastically!
For years, scientists believed that this field disappeared over 4 billion years ago, causing Mars’ atmosphere to be slowly stripped away by solar wind. But according to new research led by the University of British Columbia (UBC) has placed new constraints on when this magnetic field disappeared, indicating that Mars’ magnetic field existed sooner (and laster hundreds of millions of years longer) than previously thought.

In 2018, NASA decided that the landing site for its Mars 2020 Perseverance rover would be the Jezero Crater. At the time, NASA said the Jezero Crater was one of the “oldest and most scientifically interesting landscapes Mars has to offer.” That assessment hasn’t changed; in fact it’s gotten stronger.
A new research paper says that the Jezero Crater was formed over time periods long enough to promote both habitability, and the preservation of evidence.

Friday April 24th was China’s “Space Day,” celebrated on the 50 year anniversary of their first satellite launch. This past Friday, China marked the occasion with the announcement of the name for their first Mars Lander: Tianwen.
According to China’s National Space Administration (CNSA), Tianwen translates to “Quest for Heavenly Truth.”

After a lot of hard work spanning many years, a team of scientists have discovered something surprising. They’ve found abundant bacterial life in tiny cracks in undersea volcanic rock in the Earth’s crust. The bacteria are thriving in clay deposits inside these tiny cracks.
This discovery is generating new excitement around the hope of finding life on Mars.

The Mars Reconnaissance Orbiter (MRO) delivers once again! Using its advanced imaging instrument, the High Resolution Imaging Experiment (HiRISE) camera, the orbiter captured a breathtaking image (shown below) of the plains north of Juventae Chasma. This region constitutes the southwestern part of Valles Marineris, the gigantic canyon system that runs along the Martian equator.
