This summer, NASA’s Mars Perseverance rover is taking the next giant leap in our search for signs of life beyond Earth.
Are you hesitating to buy anti-Covid-19 toothpaste? 100 years ago, you might have found some miracle elixirs to protect you from Halley’s Comet.
Duckweed is the perfect space food: small, fast-growing and nutritious. By studying how light levels changed the production of radiation-fighting antioxidants, researchers made it even better.
A new country launches a mission to Mars. A space expert explains what this means for the Middle East and the African continent.
Why are scientists trying to grow organs at the International Space Station? People live on Earth not in zero-gravity. A stem cell expert explains why it is useful to do these experiments in space.
Australia’s space industry is booming despite the impact of coronavirus.
If gravity was half as strong, you could jump much higher.
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.
Women are in many ways ideal astronauts, but the world of space has been designed for men.
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?
The distance between the ISS and Earth is the same as about 3,850 football fields. To bring the station down, rockets will lower it a bit, and then gravity will send it crashing the rest of the way.
NASA’s new Artemis Accords will clearly test international treaties governing the extraction of resources and bans on territorial claims.
Not all teaching spaces in universities are big enough to allow students to return to normal study as the pandemic restriction ease.
The primary objective of CHEOPS is to better understand the planets that we’ve already found. And its mission is now in full swing.
Cosmologists had only been able to find half the matter that should exist in the universe. With the discovery of a new astronomical phenomenon and new telescopes, researchers just found the rest.
SpaceX’s launch of astronauts to the International Space Station will make it the first private company to launch humans to space. The effort has ramifications for NASA and spaceflight in general.
An update of 50-year-old regulations has kickstarted research into the next generation of rockets. Powered by nuclear fission, these new systems could be the key to faster, safer exploration of space.
