Mars Rovers Will Need to Dig Deeper If They Want to Find Evidence of Life

The search for life—even ancient life—on Mars is trickier than we thought. In a recent study published in the journal Astrobiology, researchers have determined that NASA’s Mars Perseverance (Percy) Rover will have to dig two meters (6.6 feet) beneath the Martian surface in order to find traces of ancient life. This is because the surface of Mars is constantly bombarded with extreme levels of solar radiation that scientists hypothesize would quickly degrade small molecules such as amino acids. The reason for this extreme level of radiation is due to the absence of a magnetic field, which scientists believe was stripped away billions of years ago when the planet’s liquid outer core ceased to produce the dynamo that created the field.

Dust Devils and Strong Winds Produce the Constant Haze on Mars

Dust is an everyday feature on Mars and wreaks havoc on various pieces of equipment humans decide to send to it, such as Insight’s continual loss of power or the losses of Opportunity and Spirit. But we’ve never really understood what causes the dust to get up into the air in the first place. That equipment that is so affected by it usually isn’t set up to monitor it, or if it is, it has been sent to a place where there isn’t much dust, to begin with. Now, that has changed with new readings from Perseverance in Jerezo crater, and the answer shouldn’t be much of a surprise – dust devils seem to cause some of the dust in the atmosphere on Mars. But strong winds contribute a significant amount too.

A Perfectly Balanced Rock Seen by Perseverance

NASA's Mars Perseverance rover acquired this image using its Right Mastcam-Z camera. Mastcam-Z is a pair of cameras located high on the rover's mast. This image was acquired on June 12, 2022 (Sol 466) at the local mean solar time of 12:20:39. Image Credit: NASA/JPL-Caltech/ASU

The Perseverance rover has begun exploring a region that looks a little like Monument Valley in Arizona and Utah in the US, or perhaps like a set on an old sci-fi movie. The rover’s science team has nicknamed the area “Hogwallow Flats,” and the rock formations in this area on Mars are stunning in their varied and sometimes absurd shapes and structures. One wonders what took place here eons ago to create the weird variety of formations.

While small, one feature catches the eye: a smaller rock that appears to be perfectly perched and balanced on top of a larger rock formation.

Perseverance Has Been Carrying a Rock in its Wheel for Over 100 Days

NASA's Mars Perseverance rover acquired this image of a rock inside the rover's wheel, along with the area in front of it using its onboard Front Left Hazard Avoidance Camera A. This image was acquired on May 26, 2022 (Sol 449). Image Credit: NASA/JPL-Caltech

Why does a Mars rover have a rock in one of its wheels? Maybe it’s because a rover doesn’t have pockets.

Who among us hasn’t picked up a great rock, carried it around, maybe saved it for a long time, or even placed it somewhere safe or special? The Perseverance rover is doing just that, having carried a random Mars rock in its wheel for quite some time.

Perseverance is Seeing A LOT of Dust Devils

While the Mars InSight lander is still waiting for a passing dust devil to clean off its solar panels, it appears the Perseverance rover sees dust devils several times a day.

A new paper detailing the first 216 days of Perseverance’s mission in Jezero Crater reports how the newest rover on Mars appears to be located in a “dust storm track” that runs north to south across the planet. Jezero Crater has particularly high levels of dust and wind activity.

Martian Dust is Starting to Darken Ingenuity’s Solar Panels

This image of NASA’s Ingenuity Mars Helicopter was taken by the Mastcam-Z instrument of the Perseverance rover on June 15, 2021, the 114th Martian day, or sol, of the mission. The location, "Airfield D" (the fourth airfield), is just east of the "Séítah" geologic unit. Credits: NASA/JPL-Caltech/ASU/MSSS.

Like every solar-panel-powered vehicle on Mars, maintaining electrical power always becomes an issue at some point in the mission. Last week, mission controllers at the Jet Propulsion Laboratory lost contact with the Ingenuity Mars Helicopter. While they were able to re-establish communications, which is done through the Perseverance rover, engineers know that keeping Ingenuity’s batteries charged is going to be increasingly difficult as the dark winter is on the way to Jezero Crater.

Ingenuity is now Scouting Ahead of Perseverance, Helping it Navigate Difficult Terrain

NASA’s Ingenuity Mars Helicopter recently surveyed a ridgeline near the ancient river delta in Mars’ Jezero Crater at request of the Perseverance rover’s science team. On the left is the full image Ingenuity acquired of the ridgeline on April 23, 2022, during its 27th flight. The science team calls the line of rocky outcrops running from the upper left to middle right of the main image “Fortun Ridge.” Enlarged at right is a close-up of one of the ridgeline’s rocky outcrops.

The Ingenuity Mars Helicopter is providing scientists a look at what is on the road ahead for the Perseverance rover. And acting as a scout, Ingenuity can tell the team what places to avoid, too.

Amazing! Ingenuity Helicopter Flies to the Perseverance Backshell and Parachute to See Them Close Up

You may recall we reported earlier this month that the Perseverance rover finally spotted its parachute and backshell off in the distance. This is the hardware that safely brought the rover to Mars surface on February 18, 2021.

But now, the incredible Ingenuity helicopter has snapped better images of those items, while it was hovering in the Martian air during its 26^th flight.

And what a mess! The poor backshell crashed to the surface, splitting into pieces.

Perseverance Begins the Next Phase of its Mission, Studying an Ancient River Bed on Mars

On February 18, 2021, NASA’s Perseverance (Percy) Rover successfully landed in the dried-up lakebed known as Jezero Crater on Mars, beaming back images and video of its descent and landing to millions of space fans living on the planet that built and launched this incredible robotic explorer. With this landing came enormous excitement for a new era of robotic exploration of the Red Planet as we slowly continue to unlock the secrets of Mars and its ancient past, to include (hopefully) finding evidence of past life.
