When you look at the Moon, you don’t see any water on its surface. That doesn’t mean there isn’t any. In fact, there’s a lot of “wetness” on the Moon, but it’s in places and forms we can’t see. Understanding where all those resources are is the subject of a study based on NASA’s Moon Mineralogy Mapper (M3) data taken from aboard the Chandrayaan-1 spacecraft.

Few scientists doubt that Mars was once warm and wet. The evidence for a warm, watery past keeps accumulating, and even healthy skepticism can’t dismiss it. All this evidence begs the next question: what happened to it?

The Moon has been a source of interest of late largely due to the focus on getting humans back to the Moon. Future human explorers though will likely be there to stay in permanent lunar bases. Making this a reality means it is of vital importance to harvest materials from the Moon and water is just one of them. Recently, ESA Announced they have secured a ride to the Moon for their Prospect package in 2027. It consists of a drill and tiny laboratory that will hunt for water and other volatiles, paving the way for human exploration.

Mars was once wet, but now its surface is desiccated. Its meagre atmosphere contains only a tiny trace amount of water vapour. But new research says the planet contains ample liquid water. Unfortunately, it’s kilometres under the surface, well out of reach.

The ESA’s Mars Express orbiter captured an image of the remains of a vast ancient lake on Mars. The remnant lake bed has been weathered and altered by the passing of billions of years. In the planet’s distant past, scientists say, it held enough water to fill Earth’s Caspian Sea almost three times over.

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.

Distant Titan is an oddball in the Solar System. Saturn’s largest moon—and the second largest in the entire Solar System—has an atmosphere denser than Earth’s. It also has stable lakes and seas of liquid hydrocarbons on its surface.
New research shows that waves on these seas are eroding Titan’s coastlines.

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?

The Moon’s polar regions are home to permanently shadowed craters. In those craters is ancient ice, and establishing a presence on the Moon means those water ice deposits are a valuable resource. Astronauts will likely use solar energy to work in these craters and harvest water, but the Sun never shines there.
What’s the solution? According to one team of researchers, a solar collector perched on the crater’s rim.

The Search for Life in our Solar System leads seekers to strange places. From our Earthbound viewpoint, an ice-covered moon orbiting a gas giant far from the Sun can seem like a strange place to search for life. But underneath all that ice sits a vast ocean. Despite the huge distance between the moon and the Sun and despite the thick ice cap, the water is warm.
Of course, we’re talking about Enceladus, and its warm, salty ocean—so similar to Earth’s in some respects—takes some of the strangeness away.
