Katarina Miljkovic We’ve all heard of earthquakes, but what about marsquakes? NASA’s InSight mission has, for the first time, recorded seismic activity coming from Mars’ interior. The observations, recorded in 2019 and published today, will help understand the red planet’s internal structure, composition and dynamics. It opens a new chapter in planetary geophysics and exploration. The NASA InSight … Read More

David Weintraub, Vanderbilt University The closest place in the universe where extraterrestrial life might exist is Mars, and human beings are poised to attempt to colonise this planetary neighbour within the next decade. Before that happens, we need to recognise that a very real possibility exists that the first human steps on the Martian surface will lead … Read More

Briardo Llorente, Macquarie University Preparations are already underway for missions that will land humans on Mars in a decade or so. But what would people eat if these missions eventually lead to the permanent colonisation of the red planet? Once (if) humans do make it to Mars, a major challenge for any colony will be to … Read More

Becky Turner Theoretical physicist and one-man-phenomenon Stephen Hawking contributed a wealth of knowledge to mankind during his lifetime. One of his recommendations was that humans would need to colonise other planets in the next hundred years to avoid annihilation. His fears took the form of deadly viruses, nuclear war, asteroid impacts, and global warming. In order to avoid … Read More

Monica Grady, The Open University It was to a great fanfare of publicity that researchers announced they had found evidence for past life on Mars in 1996. What they claimed they had discovered was a fossilised micro-organism in a Martian meteorite, which they argued was evidence that there has once been life on the Red Planet. Sadly, … Read More

Katarina Miljkovic, Curtin University This article was originally published on The Conversation. Read the original article. When we look up at Mars in the night sky we see a red planet – largely due to its rusty surface. But what’s on the inside? Launching in May, the next NASA space mission will study the interior … Read More
