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?
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.
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.

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?
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.
