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.
He’s going to have to ‘science the shit out of this’.

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.
This digital false-colour image shows the dark, narrow streaks on Martian slopes inferred to be formed by seasonal flow of water on the planet. The streaks are roughly the length of a football field.

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?
The mysterious ephemeral dark streaks on Mars.
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?
Jean Paul Santos with the finished 4x4 sub-array antenna assembly that may help rovers talk directly with Earth.
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.
Once there was water….
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.
The ice caps on Mars could have been the source of the water flows.
By comparing satellite images of Mars with mud flows on Earth, we managed to find signs of recent running water on the red planet.
Ain’t half hot: but where’s it heading?
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).
Were eruptions of pressurised goundwater once commonplace on Mars?
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.
I really hope this is the right flag.
Radiation in space could lead to cognitive decline.
There must be energy here…somewhere.
A new form of engine can capture the energy released when solid carbon dioxide turns into gas.
H G Wells’s Martians.
Literature has long imagined other worlds but now space travel and planetary colonisation look to become scientific fact.
Mars in her eyes: Hannah Earnshaw - student, scientist, adventurer.
I have always been in awe of the night sky, trying to comprehend the vastness of space and the countless wonders it contains. But I have always felt a certain dissatisfaction with only being able to see…
Something big has disturbed the red planet’s thin atmosphere.
Enormous cloud-like plumes reaching 260km above the surface of Mars have left scientists baffled. This is way beyond Mars’s normal weather, reaching into the exosphere where the atmosphere merges with…
Not the Red Planet but Utah, one of the more Mars-like areas on Earth.
Elon Musk has built a US$12 billion company in an endeavour to pave the way to Mars for humanity. He insists that Mars is a “long-term insurance policy” for “the light of consciousness” in the face of…
