Thinking outside the box has always been a strong suit of space exploration. Whether taking a picture of the Earth in a sunbeam or attempting to land a rocket on a floating ship, trying new things has been a continual theme for those interested in learning more about the universe. Now, a team from the University of Manchester has come up with an outside-the-box solution that could help solve the problem of building infrastructure in space – use astronauts themselves as bioreactors to create the building blocks of early colonies.

When it landed on Mars in February of 2021, the Perseverance rover joined a small armada of robotic explorers working hard to characterize Mars’ environment and atmosphere and determine if it ever supported life. But unlike its predecessors, one of the key objectives of the rover is to obtain samples of Martian soil and rock, which it will leave in a cache for later retrieval by a joint NASA-ESA mission.
This will be the first sample return from Mars, and the analysis of these samples will provide new insight into the geological and environmental evolution of Mars. The first attempt to obtain a sample didn’t go so well, with the sample crumbling before it was placed in the cache. Undeterred, the science team moved onto the next site and prepared to try again. A few days ago, NASA confirmed that the rover succeeded in its second attempt and has the pictures to prove it!

Mars is bombarded with radiation. Without a protective magnetic shield and a thick atmosphere like Earth’s, radiation from space has a nearly unimpeded path to the Martian surface. Our machines can roam around on the surface and face all that radiation with impunity. But not humans. For humans, all that radiation is a deadly hazard.
How can any potential human explorers cope with that?
Well, they’ll need shelter. And they’ll either have to bring it along with them or build it there somehow.
Or maybe not. Maybe they could use natural features as part of their protection.

Dust on Mars gets everywhere – including on top of ice deposited during one of Mars’ previous ice ages. Just how that dust affects the ice is still up for some debate. Adding to that debate, a recent paper by researchers at Arizona State University and the University of Washington has laid out a map between the dust content of a glacier and the brightness of its ice.

The Perseverance rover now has a new tool to help scientists and engineers figure out where the rover goes next. The new tool is the little rotorcraft that was tucked away in the rover’s belly, the Ingenuity helicopter. Ingenuity has now started doing aerial surveys to scout ahead for Perseverance.

In the last two decades, we have all grown accustomed to rovers exploring Mars. At least one rover has been active on the planet every day since January 4, 2004, when NASA’s Spirit rover landed in Gusev crater. Opportunity (2004) and Curiosity (2012) followed, each making unique journeys of discovery of their own. Perseverance (2021) is the latest and greatest of these robotic explorers, boasting a state-of-the-art in-situ resource utilization experiment to extract oxygen from the atmosphere, an accompanying helicopter to scout the path ahead, and a suite of unparalleled geology instruments. But what really sets Perseverance’s mission apart is that, for the first time, it is collecting samples of Martian rock to bring back to Earth.

One of the biggest ongoing changes in space exploration is the introduction of commercial methods into the field. Commercial launch providers like RocketLab and SpaceX have fundamentally changed the way the industry does business. Now researchers are taking their “move fast and break things” approach to another part of the industry – actual mission design.

Three months after touching down on the Martian surface, China’s Zhurong rover has completed its primary mission and is still going strong.

The search for Martian life has been ongoing for decades. Various landers and rovers have searched for biosignatures or other hints that life existed either currently or in the past on the Red Planet. But so far, results have been inconclusive. That might be about to change, though, with a slew of missions planned to collect even more samples for testing. Mars itself isn’t the only place they are looking, though. Some scientists think the best place to find evidence of life is one of Mars’ moons.

Despite decades of exploration and study, Mars still has its fair share of mysteries. In particular, scientists are still trying to ascertain what happened to the water that once flowed on Mars’ surface. Unfortunately, billions of years ago, the Martian atmosphere began to be stripped away by the solar wind, which also resulted in the loss of its surface water over time – although it was not entirely clear where it went and what mechanisms were involved.
To address this, a team of scientists recently consulted data obtained by three orbiter missions studying the Martian atmosphere. In the process, they found evidence that the smaller regional dust storms that happen almost annually on Mars are making the planet drier over time. These findings suggest that storms are a major driving force behind the evolution of Mars’ atmosphere and its transition to the freezing and desiccated place we know today.
