Getting to Mars with current rocket technology will use massive amounts of fuel to move very small cargoes. There is a more fuel-efficient way.

What viewing on the International Space Station tells us about life among the stars.
Increasing Australia’s role in the billion-dollar global space industry has hardly raised a mention in this year’s federal election campaign.
Scientists are working out how to grow plants in space, ready to use them as food when we visit other planets.
NASA’s Asteroid Redirect Mission has had its funding cut. Here’s why politicians should think again.
Just about anyone can get a tiny, cheap satellite into orbit these days. As we consider how to deploy them responsibly, inspiration comes from an amateur community of enthusiasts.
After half a century of trying, scientists have finally caught a glimpse of the magnetic process that fuels space weather and the northern lights.
The increasingly rapid pace of exoplanet discoveries must mean it is only a matter of time until astronomers find another Earth.
A philosopher argues that now is the time to figure it out, before we make the inevitable discovery of extraterrestrial life.
Why weightlessness in space is about balancing forces rather than a lack of gravity.
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.
