There’s at least one small bit of good news in these challenging Covid-19 times. And it’s playing out on the surface of Mars. In a brief Tweet, NASA says that using InSight’s robotic arm to push the Mole into the ground is working, somewhat.

What do coal, crude oil, and truffles have in common? Go ahead. We’ll wait.
The answer is thiophenes, a molecule that behaves a lot like benzene. Crude oil, coal, and truffles all contain thiophenes. So do a few other substances. MSL Curiosity found thiophenes on Mars, and though that doesn’t conclusively prove that Mars once hosted life, its discovery is an important milestone for the rover. Especially since truffles are alive, and oil and coal used to be, sort of.

The Curiosity rover on Mars has captured the most detailed panoramic image ever taken of the Red Planet’s surface. The image is made from over 1,000 images, containing 1.8 billion pixels of the Martian landscape, with 2.43 GB of high-resolution planetary goodness.
“This is the first time during the mission we’ve dedicated our operations to a stereo 360-degree panorama,” said Curiosity Project Scientist Ashwin Vasavada.

Want to look inside a deep, dark pit on Mars? Scientists and engineers using the HiRISE Camera on board NASA’s Mars Reconnaissance Orbiter have done just that.
From its orbit about 260 km (160 miles) above the surface, HiRISE can spot something as small as a dinner table, about a meter in size. But can it look inside a cave-like feature on the Red Planet and actually resolve any details inside this pit?

The InSight lander has been on the surface of Mars for about a year, and a half dozen papers were just published outlining some results from the mission. Though InSight’s primary mission is to gather evidence on the interior of Mars—InSight stands for Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport—the lander also keeps track of Martian Meteorology. A new paper reports that InSight has found gravity waves, swirling dust devils, and a steady background rumble of infrasound.

The NASA and DLR InSight lander has been on Mars for over a year now. The mission has faced significant challenges getting its HP3 (Heat Flow and Physical Properties Package) into the subsurface, but the spacecraft’s other instruments are working as intended. Now, researchers have published six papers outlining some of the mission’s scientific results.

There may be no life on Mars, but there’s still a lot going on there. The Martian surface is home to different geological process, which overlap and even compete with each other to shape the planet. Orbiters with powerful cameras give us an excellent view of Mars’ changing surface.

Billions of years ago, Mars had liquid water on its surface in the form of lakes, streams, and even an ocean that covered much of its northern hemisphere. The evidence of this warmer, wetter past is written in many places across the landscape in the form of alluvial fans, deltas, and mineral-rich clay deposits. However, for over half a century, scientists have been debating whether or not liquid water exists on Mars today.
According to new research by Norbert Schorghofer – the Senior Scientist at the Planetary Science Institute – briny water may form intermittently on the surface of Mars. While very short-lived (just a few days a year), the potential presence of seasonal brines on the Martian surface would tell us much about the seasonal cycles of the Red Planet, as well as help to resolve one of its most enduring mysteries.

There are around 61,000 meteorites on Earth, or at least that’s how many have been found. Out of those, about 200 of them are very special: they came from Mars. And those 200 meteorites have been important clues to how Mars formed in the early Solar System.

This summer, between mid-July and early August, the Mars 2020 rover will launch, reaching Mars by February of 2021. Once it touched down in the Jezero Crater, it will carry on in the footsteps of its predecessor – the Curiosity rover. This will include searching for evidence of Mars’ past habitability and the possible existence of life (past and present), as well as a sample-return mission.
To accomplish these tasks, the Mars 2020 rover will be relying on an advanced suite of instruments. One of these is the SuperCam, which includes a camera, a laser, and spectrometers and is mounted to the rover’s mast (or “head”). Once operational, this instrument will be used to study the chemistry and mineralogy of Martian rocks and (with any luck) find evidence of fossilized microbial life on Mars.
