Despite clear air as a result of the pandemic reducing human activities, our emissions still soar.
How do people in a special airplane flight get to float like there is no gravity – just like astronauts? An aerospace engineer explains.
Martian meteorites allow scientists here on Earth to decode that planet's geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.
Empathy and scientific knowledge will be key for astronauts looking to travel to Mars.
When it comes to commercial space tourism, suborbital flight are the first frontier. But what are the risks? Are there health requirements? What should you know before taking such a way-out trip?
NASA's new Artemis Accords will clearly test international treaties governing the extraction of resources and bans on territorial claims.
About 770 Australian entities are already developing space-related infrastructure, most of which are privately owned.

NASA's InSight lander has recorded the first evidence of earthquake-like tremors on Mars. The discovery opens a new chapter in our understanding of the geological processes at play on another world.
Two defunct satellites passed within metres of one another, prompting renewed focus on the dangers of space debris. But with many satellites treated as military secrets, how do we track the hazards?
By understanding how bushfire maps are created, and what their features represent, you can get better at spotting fake ones.
We pulled four before-and-after NASA satellite images and asked bushfire researcher Grant Williamson to reflect on the story they tell.
Scientists can't expect the unexpected if they're not open-minded about how their theories might be wrong.
