This week, NASA has discovered great similarities between the Earth and Mars and Pluto. But when it comes to the potential for life, Mars is an increasingly hot favourite.
Review: stranded on Mars' desolate landscape, a cocky, endearing protagonist breathes life into this survival tale.
NASA has set a target date of 2030 for a manned mission to Mars. With no real scientific breakthroughs needed, success depends on developing the proper technology.
Hollywood may already have done it but when we eventually send real astronauts to Mars, what medicines should we arm them with? And will they work the same way as they do on Earth?
Water on Mars could mean life on Mars. But how do we explore it without destroying it?
The latest of the spate of recent space films may be the brightest, but it doesn't inspire this author to head to the Red Planet.
The Martian is a rare film that seeks to use science to enhance the plot, and gives a sense of the splendour of the Red Planet.
Now that we have discovered liquid water on the surface of Mars, what does this mean for the prospects of finding life there, past or present?
New research suggests that salty water exists on Mars in the summer months. But that wouldn't be the first time we hear of water on the red planet. So what's new and what isn't?
New research provides a compact but powerful way for Mars rovers to communicate directly with Earth via an array of smaller antenna elements, bypassing the need for an intermediary.
Space scientists have a busy decade ahead with plans to visit Jupiter, Mars, Mercury and other interplanetary bodies all on the cards.
Everything in space is so far away, but probes bring us closer.
Some atomic ratio detective work on our solar system neighbors tells us a lot about their watery pasts. That Venus and Mars are mostly dry now could be a cautionary tale for us on the Blue Planet.
By comparing satellite images of Mars with mud flows on Earth, we managed to find signs of recent running water on the red planet.
Astrophysicists found out after the January 2014 solar flare that their predictions of solar weather were not very accurate. Here's the fix (kind of).
For centuries, scientists have wondered how water channels on Mars formed. Our model suggests that they were caused by water erupting from subsurface lakes on the ancient planet.
4,000 days on Mars and still going strong: one scientist's experience of working with Opportunity.
Radiation in space could lead to cognitive decline.
A new form of engine can capture the energy released when solid carbon dioxide turns into gas.
Literature has long imagined other worlds but now space travel and planetary colonisation look to become scientific fact.
