NASA is Keeping an Eye on InSight from Space

This image from October 2024 shows the InSight lander at its final resting place on Mars. As dust covers its solar panels the lander is taking on the same colour as the Martian surface. The image was captured by the Mars Reconnaissance Orbiter. Image Credit: NASA/JPL-Caltech/University of Arizona

The InSight Lander arrived on Mars in 2018 to study the planet’s interior. Its mission ended prematurely in December 2022 after its solar panels were covered in the planet’s ubiquitous dust. NASA’s Mars Reconnaissance Orbiter captured an image of InSight recently and will continue to do so as the Martian dust slowly and inexorably reclaims the lander.

NASA Lays Out Two New Options for Mars Sample Return

Months after deciding that its previous plan for bringing samples back from Mars wasn’t going to work, NASA says it’s working out the details for two new sample return scenarios, with the aim of bringing 30 titanium tubes filled with Martian rocks and soil back to Earth in the 2030s.

One scenario calls for using a beefed-up version of NASA’s sky crane to drop the required hardware onto the Red Planet’s surface, while the other would use heavy-lift commercial capabilities provided by the likes of SpaceX or Blue Origin.

NASA Administrator Bill Nelson said the space agency plans to flesh out the engineering details for each option over the course of the next year and make its choice in 2026. But that all depends on what Congress and President-elect Donald Trump’s administration want to do.

New Study Explains How Mars Dust Storms Can Engulf the Planet

Mars is well-known for its dust storms, which occur every Martian year during summer in the southern hemisphere. Every three Martian years (five and a half Earth years), these storms grow so large that they are visible from Earth and will engulf the entire planet for months. These storms pose a significant threat to robotic missions, generating electrostatic charges that can interfere with their electronics or cause dust to build up on their solar panels, preventing them from drawing enough power to remain operational.

While scientists have studied these storms for decades, the precise mechanisms that trigger them have remained the subject of debate. In a new study, a team of planetary scientists at the University of Colorado Boulder (CU Boulder) has provided new insight into the factors involved. According to their findings, relatively warm and sunny days may kick off the largest storms every few years. These could be the first step toward forecasting extreme weather on Mars, which is vital for future crewed missions to Mars.

Could There Be Bacteria Living on Mars Today?

Mars is often considered to be the planet most similar to the Earth. Earth however, is capable of supporting life, Mars on the other hand could not. There was once a time when it was warmer and wetter and could support life. Exploring life on Earth shows us that bacteria known as extremophiles can live in the most harsh conditions on Earth, it may just be possible that there are places on Mars that could also support these hardy forms of life. A new paper explores that possibility by studying the most extreme Earth-based bacteria that could survive under ground on Mars.

Crisscrossing Dust Devil Tracks Across the Surface of Mars

An incredible image of Mars has been released that captures the relentless activity of dust devils, swirling across the planet’s surface. These Martian whirlwinds form, move across the surface and dissipate before others take their place. The image was taken by the HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter in September 2022 and shows part of the Haldane Crater, where dust devils have left their mark on the landscape. Scientists study the image tracks and the rate at which dust accumulates on Mars, helping them better understand the planet’s atmospheric processes.

Ingenuity became the first aircraft to fly on another world in the first half of 2021. It explored the Martian terrain from above proving that powered air flight was a very efficient way to move around alien worlds. Now NASA have released a computer rendering of their next design, the Mars Chopper!

Where’s the Most Promising Place to Find Martian Life?

New research suggests that our best hopes for finding existing life on Mars isn’t on the surface, but buried deep within the crust.

Archaeology On Mars: Preserving Artifacts of Our Expansion Into the Solar System

There's something wistful about this image, one of the InSIGHT missions final ones before it succumbed to Mars' dust storms. One anthropologist points out that this is now a historical artifact worthy of preservation, as are other spacecraft and equipment on Mars. Image Credit: NASA/JPL-Caltech

In 1971, the Soviet Mars 3 lander became the first spacecraft to land on Mars, though it only lasted a couple of minutes before failing. More than 50 years later, it’s still there at Terra Sirenum. The HiRISE camera NASA’s Mars Reconnaissance Orbiter may have imaged some of its hardware, inadvertently taking part in what could be an effort to document our Martian artifacts.

Is it time to start cataloguing and even preserving these artifacts so we can preserve our history?

Some anthropologists think so.

NASA Thinks it Knows Why Ingenuity Crashed on Mars

NASA’s Ingenuity helicopter sent its final signals to Earth in the earlier part of the year. Engineers have been studying these and have started to piece together a picture of events that led up to its final flight. They concluded that data provided by the navigation system was inaccurate leading to a chain of events that caused its ultimate demise. One of the biggest problems it seems is that the terrain was smooth leading to a lack of landmarks during Flight 72.

Other Liquids Could Be Forming Minerals on Mars

At left: Steel is seen to corrode into siderite (FeCO3) when immersed in subcritical liquid carbon dioxide (LCO2). At right: Samples of albite (a plagioclase feldspar) and a sandstone core are observed to form red rhodochrosite (MnCO3) when exposed to supercritical CO2 in the presence of a water solution with potassium chloride and manganese chloride, with particularly strong reaction near the interface of the two solutions. In both experiments, water saturation is provided by floating LCO2 on the water. Under the lower pressure conditions characteristic of early Mars, the water would float on the LCO2.

Most people will think of a dry arid landscape when they think of Mars. When seen from orbit, dry river channels and lake-beds can be seen along with mineral deposits thought to be the created in the presence of liquid water. A team of researches now suggest that liquid carbon dioxide could also explain the features seen. On Earth, a process known as carbon sequestration liquefies CO2 which is buried underground. There are a number of mechanisms that could explain the liquid CO2 underground the researchers suggest.
