Back in November 2018, NASA announced that the Mars 2020 rover would land in the Jezero Crater. Jezero Crater is a geologically diverse area, with an alluvial fan of sediment deposited by an incoming river. That sediment may contain preserved ancient organic molecules, and the deposit is clearly visible in satellite images of the Crater.
But the crater holds something else that has scientists intrigued, something that doesn’t show up so clearly in visible light images: a “bathtub ring” of carbonates, which scientists think could hold fossils.

This is sad news. After finding what seemed like a solution to the Mole’s difficulties on Mars, engineers are stymied again. The Mole, or Heat Flow and Physical Properties Package (HP3) has bounced half-way out of its hole.
It’s like Groundhog Day on Mars. If the Mole bounces out of its hole, it means six more weeks of engineers scratching their heads to come up with a solution.

After months of setbacks, NASA says that the InSight Lander’s Mole is working again.
InSight landed on Mars on Nov. 26 2018 in Elysium Planitia. Its mission is to study the interior of the planet, to learn about how Mars and other rocky planets formed. InSight (Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport) is a NASA mission with other partners, including the DLR (German Aerospace Center.)

If the Curiosity rover was paranoid, would it feel like it was being watched? Well, it is being watched, by its brother in orbit, the Mars Reconnaissance Orbiter. The MRO watched Curiosity as it travelled through the ‘Clay-Bearing Unit‘ in Gale Crater, during June and July, 2019.

NASA and the DLR are making some progress with the Mole. The Mole has been stuck for months now, and NASA/DLR have been working to get it unstuck. After removing the mole’s housing to get a better look at it with InSight’s cameras, the team came up with a plan.

From some viewpoints, Mars is kind of like a skeleton of Earth. We can see that it had volcanoes, oceans, and rivers, but the volcanoes no longer fume and the water is all gone. A new image from the ESA’s Mars Express drives the point home.

What happened to Mars? If Mars and Earth were once similar, as scientists think, what happened to all the water? Did there used to be enough to support life?
Thanks to the Mars Science Laboratory (MSL) Curiosity, we’re getting a better picture of ancient Mars and what it went through billions of years ago. A new study published in Nature Geoscience says that Mars likely underwent alternating periods of wet and dry, before becoming the frigid, dry desert it is now. Or at least, Gale Crater did.

The mole is still stuck.
The mole is the name given to the Heat Flow and Physical Properties Package (HP3) instrument on NASA’s Mars InSight lander. It’s job is to penetrate into the Martian surface to a depth of 5 meters (16 ft) to measure how heat flows from the planet’s interior to the surface. It’s part of InSight’s mission to understand the interior structure of Mars, and how it formed.
But it’s stuck at about 35 centimers (14 inches.) The mole can do science shy of its maximum depth of 5 meters, but not this shallow. And NASA, and the DLR (German Aerospace Center) who provided the mole, have a new plan to fix it.

The SEIS (Seismic Experiment for Interior Structure) instrument on NASA’s InSight lander has sensed 21 Marsquakes since it was deployed on December 19th, 2018. It actually sensed over 100 events to date, but only 21 of them have been identified as Marsquakes. SEIS is extremely sensitive so mission scientists expected these results.
SEIS is a key part of InSight, NASA’s mission to understand the interior of Mars. Along with other instruments, it’ll help scientists understand what’s going on inside Mars.

In 2017, Elon Musk laid out his grand sweeping plans for the future of SpaceX, the company that would take humanity to Mars. Over decades, tens of thousands of Starship flights would carry a million human beings to the surface of the Red Planet, the minimum Musk expects it’ll take to create a self-sustaining civilization.
