As the European Space Agency’s ExoMars mission begins its six-month journey to the planet, we talk to its director-general Professor Jan Woerner about drilling into the Martian surface and pose the crucial question: is there life on Mars? We also find out how scientists are recycling historic data to create a virtual reality simulation of the planet’s terrain, and explore some of the obstacles to a crewed Martian mission.
Sending astronauts to Mars poses several large challenges, among them a long journey filled with life-threatening radiation from cosmic ray exposure and solar flares. Not to mention the fact that we haven’t yet worked out how to get them back again.
There could have been life under the surface of Mars, according to Prof. Jan Woerner, Director General of the European Space Agency (ESA), which in March is launching its ExoMars mission to find out.
To mark the European year of cultural heritage, Horizon explores how science is helping to uncover more about our past and to preserve our art, landscapes, buildings and ways of life for the future. We discover why prehistoric humans chose to paint rock art where they did, and how farming techniques from hundreds of years ago could help fight climate change today. Plus, we learn how cultural heritage feeds into European identities and what can be done to prevent the destruction of historical sites during wartime.
The way we work is undergoing a major shift thanks to technological development and demographic change and, this month, Horizon looks at how research is helping us stay ahead of the game. We find out how decisions made early in your career could determine when you retire, and how to get the most out of the relationship between humans and machines in factories. We also investigate some of the ethical issues that could arise in the jobs of the future and how best to take them into account.
The challenge of how to rebuild society following conflict is a difficult question that arises all too frequently, but recent studies have demonstrated that putting people at the centre of the process and enabling cooperation on politically neutral issues can help build peace.
Global warming is a reality – but just how bad will it be? A study published in January 2018 claims to halve the uncertainty around how much our planet's temperature will change in response to rising carbon dioxide (CO2) levels, potentially giving governments more confidence to prepare for the future.
Where does one start to fix a broken society?
A new analysis all but rules out the best and worst warming scenarios – but not everyone believes it.
Destruction of cultural heritage sites can be a war crime as they form part of people's emotional landscape, according to Dr Margarete van Ess.
