35 years ago Sally Ride became the first American woman in space. But rather than focus on her own extraordinary achievements, her passion became boosting the number of girls pursuing STEM. Another pioneering astronaut remembers her friend and colleague.

Australia occupies a unique location vital for supporting NASA and ESA deep-space missions.
Following NASA's latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.

Astronomers are gathering an exponentially greater amount of data every day – so much that it will take years to uncover all the hidden signals buried in the archives.
Time to peer below the swirling clouds of Jupiter.

Now's a great time to see Jupiter as it's about to be the closest to Earth for some time. Time too to catch up with the latest on the Juno mission, exploring the largest planet in our Solar System.

The little-known Rossi X-ray Timing Explorer spacecraft was like a Geiger counter for the universe, listening to black holes and zombie stars.
InSight aims to figure out just how tectonically active Mars is, and how often meteorites impact it.
What is Mars made of? We hear from a scientist who will be part of the team analysing 'marsquake' seismic data and orbital imagery from the InSight mission to the red planet.
NASA’s Transiting Exoplanet Survey Satellite (TESS) successfully launched on a SpaceX Falcon 9.
The new planet-hunting telescope TESS was successfully launched today by NASA, and Australia will play a key role in checking out any new worlds it discovers.
TESS will soon be our eye in the sky.

When NASA first started planning the Kepler mission, no one knew if the universe held any planets outside our solar system. Thousands of exoplanets later, the search enters a new phase.

Google's artificial intelligence has been taught to look for planets around other stars. It's already making new discoveries that scientists have missed.
A new trajectory means the mission to uncover core facts about the asteroid belt will happen sooner than planned.
Who’s rushing? The Chinese Long March 5 rocket lifts off.
Dreams of new footprints on the moon are more about domestic politics than foreign policy.

The discovery of tiny ripples in space from the violent collision of dense stars could help solve many mysteries – including where the gold in our jewellery comes from.
Off to court…
Future Mars colonists may want to form their own legal system. What would stop them?
Olympus Mons, biggest volcano in the Solar System.
They erupted for billions of years and make Earth's volcanoes look like molehills. Here's what we know and what we don't know about them.
Without satellites, modern technologies such mobiles phones and GPS would not exist.

We've all seen videos of satellites being blasted off into space - but once they're locked in orbit around the earth, how do we bring them back down?
A girl takes a close look at the world’s first artificial.
satellite, the Soviet-made Sputnik I.
Our fascination with space shows no signs of slowing down, 60 years after the Soviet Union launched the world's first satellite, Sputnik.
