To prepare for future Mars missions, scientists collect samples and simulate communications conditions from volcano parks on Earth.

The space industry and global interest in all matters inter-planetary is growing.
Studies from our own planet shed light on whether there could be life in a subglacial lake on Mars.
Life could have evolved on exoplanets Kepler-452b and Kepler-62e, according to a new study.
Following NASA’s latest discovery of organic matter on the red planet, new findings in a salt lake in California could point to where to look for alien life.
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.
If you want to live on Mars, you’re going to need to grow food. Seeds are naturally equipped to handle challenging Earth environments, but how well can they survive what they’ll encounter off-planet?
Even if alien life is never discovered, all is not lost.
Cassini is about to crash into Saturn to avoid contaminating its habitable moon Enceladus.
There has been much excitement this week about the possibility of water – and life – on some newly discovered exoplanets. But we can look closer to home for evidence of ET.
Complex life may be rare in the universe because most planets become either too hot or too cold before life has a chance to get a foothold. This might explain why we have yet to bump into E.T.
New research gives a clue about what happens when there are two habitable worlds in the same solar system.
As far as underwhelming headlines go: “No Alien Life Found on Comet” must rank very close to the top. An article with this title appeared in the Guardian on July 6 in response to a story claiming that…
One of the many unanswered questions about the origin of life on Earth is: where did organic molecules – those containing carbon, from which life as we know it is derived – come from? Given the conditions…
Scientists have simulated the electrical energy produced in the Earth that may have led to life 3.5 billion years ago. Using a fuel cell, researchers from the University of Leeds and NASA’s Jet Propulsion…
Could life really exist on other planets? The most positive scientific answer we can offer is: well, maybe, but we do not yet have enough evidence for or against. Yet Milton Wainwright and colleagues from…
Earth will be able to support life for at least another 1.75 billion years, according to new research by astrobiologists…
A recent article in Nature Geoscience suggests that at least one large, deep crater on Mars may once have supported an alkaline lake that was fed by water from kilometres below the planet’s surface. This…
Earth is the only planet in our solar system with a long-term, stable supply of liquid water – essential for the formation and evolution of all organic life. But this doesn’t mean there aren’t other pockets…
Life originated on Earth about four billion years ago. Death, sex and multicellularity came along about a billion years later. According to our new atavistic model, cancer came with multicellularity. About…
