It’s an ambitious plan to send a micro-spaceship to our stellar neighbour but is this possible with today’s technology or even technology in the near future?
Building a tiny starship may be doable. The big challenge will be making sure it survives all the hazards in interstellar space.
Yes, it really is rocket science.
The Last Man on the Moon is much more than a biographical documentary – it is a gripping account of human endeavour.
People and machines need to be able to interact and communicate effectively. Right now we – and they – can’t. But without that, we risk missing the potential benefits of collaboration.
After last summer’s Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here’s some of what scientists have learned so far from that rich, slow cache.
We’re on the cusp of being able to consistently launch and land rockets, greatly reducing the cost of space travel. But how long before there’s a Millennium Falcon in every garage?
Scott Kelly’s year in space is over. Now we need to know what it did to his body.
We already have much of the technology we’d need to start a colony on another planet.
No one nation should be allowed to go it alone and develop a mining industry in space. It needs an international effort and Australia, with a long history in mining, can play its part.
The spectacular science of quasars, no hair theorum and spaghettification.
The 50th anniversary of Luna 9’s first soft moon landing reminds us how difficult landing a spacecraft is.
We should honour the dead by striving to go further.
No warp drives or worm holes required.
What’s life like in a hostile environment that’s literally out of this world?
Scientists on the International Space Station are preparing for one of the biggest DIY challenges of their lives.
From the high-speed journey to Jupiter to solar eclipses, meteor showers and planetary alignments visible in the skies above – add these space highlights to your 2016 calendar.
Dawn’s mission director and chief engineer describes his ‘dream come true’ job – and how the new data coming back from Ceres could unlock some of the secrets of the earliest days of our solar system.
Four decades later, I find myself surveying 13 billion years of cosmic history and mapping events that really did happen a long time ago in galaxies far, far away.
