The idea of building settlements on Mars is a popular goal of billionaires, space agencies and interplanetary enthusiasts.

But construction demands materials, and we can’t ship it all from Earth: it cost US$243 million just to send NASA’s one ton Perseverance Rover to the Red Planet.

Unless we’re building a settlement for ants, we’ll need much, much more stuff. So how do we get it there?

CSIRO Postdoctoral Fellow and Swinburne alum Dr. Deddy Nababan has been pondering this question for years. His answer lies in the Martian dirt, known as regolith.

“Sending metals to Mars from Earth might be feasible, but it’s not economical...

A giant bubble of gas and dust surrounds the red supergiant DFK 52, likely created in a powerful outburst 4,000 years ago. Astronomers are baffled at how the star survived without going supernova, and suspect a hidden companion may have played a role. This discovery could reveal clues about the final stages of massive stars.

Astronomers from Chalmers University of Technology, Sweden, have discovered a vast and expanding bubble of gas and dust surrounding a red supergiant star – the largest structure of its kind ever seen in the Milky Way...

The ancient Japanese art of paper-folding, or origami, is already inspiring the design of the next generation of space vehicles, but now there’s a new family of origami shapes that could make them even more compact and reliable.

Larry Howell at Brigham Young University and his colleagues have developed a new class of origami structures called bloom patterns that fold up flat and unfold like flower petals. These clever folding designs could also be used for other structures in space, such as telescopes and solar arrays.

Origami-based designs are perfect for spacecraft because they can be made to fol...

To see the world in a grain of sand: Investigating megaripples at Kerrlaguna on Mars

On Mars, the past is written in stone—but the present is written in sand. Last week, Perseverance explored inactive megaripples to learn more about the wind-driven processes that are reshaping the Martian landscape every day.

After wrapping up its investigation at the contact between clay a...
