In the early 20th century a Russian scientist – regarded as the father of rocketry – made some novel predictions on where we would be in space in the 21st century. So how accurate was he?
No human has been to the moon since 1972. But India, China and Russia would like to change that, and soon.
Dreams of new footprints on the moon are more about domestic politics than foreign policy.
Scientists used to think that the ocean on Enceladus would be transient, perhaps freezing after a few million years. A new study suggests this isn't the case.
Private companies are increasingly challenging national space agencies in a new space race, which comes with great opportunities but also huge risks.
Musk’s audacious plan to blast people to Mars by 2024 glosses over some important social and political challenges that SpaceX will need to successfully navigate to get off the ground.
Planetary protection protocols try to make sure we don't seed places like Mars with life from our planet. An astrobiologist argues they're misguided – especially with human astronauts on the horizon.
Space exploration is exciting - but there are barriers for humans hoping to visit and even stay on planets. Buried ice on Mars could be a water source for interplanetary visits of the future.
The last signals from Cassini space probe before it burns up in Saturn's atmosphere will tracked by the Canberra Deep Space Communication Complex.
The Cassini space probe discovered liquid lakes, poisonous gases and the basic elements of life on Saturn's moon, Titan.
The Cassini space probe took us up close and through the beautiful rings of Saturn. It captured some amazing images, and even the sound of the rings during its mission.
The Cassini space probe discovered several new moons on its mission to Saturn, and revealed fresh views of the moons we already knew about.
With only days to go before NASA's Cassini space probe ends its two-decade mission to explore Saturn, what has it revealed about the ringed planet, the second largest in our solar system?
Humanity is the real target for these recordings which continue to inspire us to better understand ourselves and our place in the cosmos.
Even if alien life is never discovered, all is not lost.
Operating the two spacecraft that make up BebpiColombo will be harder than rocket science, says a member of its science team.
Cassini is about to crash into Saturn to avoid contaminating its habitable moon Enceladus.
We could learn a lot from any mission to send people to Mars, such as whether there's life elsewhere in the universe or even the technology for new household appliances.
We may need to re-think our models of Jupiter’s formation thanks to the first results from Juno probe orbiting the planet, and new observations from Earth.
There are loads of applications for 3D printers in space.
