How will future robotic explorers navigate the difficult subterranean environments of caves and lava tubes on the Moon and Mars? This is what a recent study published in Science Robotics hopes to address as a team of researchers from Stanford University investigated the use of a novel robotic explorer called ReachBot, which could potentially use its unique mechanical design to explore deep caves and lava tubes on the Moon and Mars in the future.

What would the economy of a future Mars society look like, and how could it be self-sustaining while being completely sovereign from Earth and its own economy? This is what a recent study submitted to Space Policy hopes to address as a sole researcher discusses a model that could be used for establishing economic freedom on Mars, enabling both monetary and political stability across all Red Planets settlements. This study holds the potential to help scientists, economists, and world leaders better understand plausible governmental systems used by human settlers on other worlds while maintaining sovereignty from Earth and its own governmental law and order.

On May 30th, the Mars Curiosity rover was just minding its own business exploring Gediz Vallis when it ran over a rock. Its wheel cracked the rock and voila! Pure elemental sulfur spilled out. The rover took a picture of the broken rock about a week later, marking the first time sulfur has been found in a pure form on Mars.

If history has taught us one thing, it is that science fiction often gives way to science fact. Consider the Star Trek communicator and the rise of flip phones in the late 1990s and early 2000s, or how 2001: A Space Odyssey predicted orbiting space stations and reusable space planes – like the International Space Station (ISS) and the Space Shuttle. And who can forget Jules Verne’s classic, From the Earth to the Moon, and how it anticipated that humans would one day walk on the Moon? Almost a century later, this dream would be realized with the Apollo Program.
The latest comes from Cornell University, where a team of researchers has developed a novel in-suit urine collection and filtration system inspired by the suits the Fremen wore in Frank Herbert’s Dune. Once integrated into NASA’s standard spacesuit—the Extravehicular Mobility Unit (EMU)—this system has the potential to provide astronauts with additional water while reducing the risk of hygiene-related medical events. In short, the stillsuit technology has the potential to enable longer-duration missions on the surface of the Moon, Mars, and orbit.

In the coming decades, multiple space agencies and private companies plan to establish outposts on the Moon and Mars. These outposts will allow for long-duration stays, astrobiological research, and facilitate future Solar System exploration. However, having crews operating far from Earth for extended periods will also present some serious logistical challenges. Given the distances and costs involved, sending resupply missions will be both impractical and expensive. For this reason, relying on local resources to meet mission needs – aka. In-Situ Resource Utilization (ISRU) – is the name of the game.
The need for ISRU is especially important on Mars as resupply missions could take 6 to 9 months to get there. Luckily, Mars has abundant resources that can be harvested and used to provide everything from oxygen, propellant, water, soil for growing food, and building materials. In a recent study, a Freie Universität Berlin-led team evaluated the potential of harvesting resources from several previously identified deposits of hydrated minerals on the surface of Mars. They also presented estimates of how much water and minerals can be retrieved and how they may be used.

After 100,000 orbits and almost 23 years on Mars, NASA’s Mars Odyssey orbiter has seen a lot. The spacecraft was sent to map ice and study its geology, but along the way, it’s captured more than 1.4 million images of the planet.
A recent image captured the Solar System’s tallest mountain and volcano, Olympus Mons.

NASA’s InSight Mars Lander faced some challenges during its time on the red planet’s surface. Its mole instrument struggled to penetrate the compacted Martian soil, and the mission eventually ended when its solar panels were covered in dust. But some of its instruments performed well, including SEIS, the Seismic Experiment for Interior Structure.
SEIS gathered Mars seismic data for more than four years, and researchers working with all of that data have determined a new meteorite impact rate for Mars.

When astronauts land on Mars someday, they might have to live in lava caves or lava tubes to survive the harsh radiation that rains down on the Martian surface every second. But which caves could offer them the best chance of survival? This is what a recent study presented at the 55th Lunar and Planetary Science Conference hopes to address as Dr. Anatoliy P. Vidmachenko from the National University of Life and Environmental Sciences of Ukraine investigated where, how, and why lava tubes and lava caves could aid future Mars astronauts regarding their survival. This study holds the potential to help scientists and engineers help mitigate risks for future Mars astronauts and what steps that need to be taken to make that a reality.

NASA’s Perseverance Rover has left Mount Washburn behind and arrived at its next destination, Bright Angel. It found an unusual type of rock there that scientists are calling ‘popcorn rock.’ The odd rock is more evidence that water was once present in Jezero Crater.

Earth is a seismically active planet, and scientists have figured out how to use seismic waves from Earthquakes to probe its interior. We even use artificially created seismic waves to identify underground petroleum-bearing formations. When the InSIGHT (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander was sent to Mars, it sensed Marsquakes to learn more bout the planet’s interior.
Researchers think they can use Marsquakes to answer one of Mars’ most pressing questions: Does the planet hold water trapped in its subsurface?
