Personnel at NASA and the DLR have been working for months to get InSight’s Mole working. They’re at a disadvantage, since the average distance between Earth and Mars is about 225 million km (140 million miles.) They’ve tried a number of things to get the Mole into the ground, and they may finally be making some progress.

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 less than four years, NASA plans to send astronauts back to the Moon for the first time since the Apollo era (Project Artemis). But this time, NASA plans to build the infrastructure needed to ensure a “sustainable program” of lunar exploration. In short, we’re going back to the Moon and this time, we plan to stay! To help them get there, the agency has partnered with commercial aerospace companies to provide logistical support.
In addition, NASA recently named three companies to develop vehicles for the Artemis missions that will be capable of landing astronauts on the lunar surface. They include the commercial space powerhouses SpaceX and Blue Origin, as well as the Alabama-based Dynetics, all of whom are tasked with developing Human Landing Systems (HLS) that can be deployed from their respective heavy launch systems (or another commercial provider).

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.

Flying low over the surface of Mars. Don’t tell me you haven’t dreamed about it, especially with some of the ‘Mars flyover’ videos that have been produced over the years using data from the orbital missions. And if all goes well – global pandemic not withstanding — a helicopter will be on its way to the Red Planet in just a few months.

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.”

In the near future, sample-return missions from Mars will finally be a reality. For decades, scientists have analyzed the composition of Martian rocks and soil by either sending rovers to the surface or by examining meteorites that came from Mars. But with missions like Perseverance, which are equipped with a sample cache instrument, it won’t be long before Martian rocks are brought back to Earth for study.
Similar to how the Apollo astronauts brought back Moon rocks, which revealed the existence of water on the Moon and its similarity to Earth, Martian rocks could reveal a great deal about the formation and evolution of the Red Planet. The question is, what rocks should be returned? This is the question that the international Mars Sample Return campaign is considering on the eve of Perseverance’s launch.
