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.
Robots won’t replace doctors any day soon, but they can already help medical professionals do amazing things. This month, Horizon looks at how robots will someday perform remote physical and ultrasound examinations so doctors can make a diagnosis from a distance, and medical avatars for elderly people that help them stay fit and safe. Plus, we see how computer games could make young people lead healthier lifestyles and how to give self-help apps more scientific merit.
How will we have enough food to feed another 2 billion people by the middle of this century without destroying our planet? Agriculture is already one of the biggest contributors to climate change. This month, we hear from scientists designing disease-resistant crops using gene editing, packing more calcium into finger millet, and resurrecting ancient crop varieties to offset the sector’s environmental impact. Plus, we hear from Dr Manoj Dora about so-called lean agriculture, which is looking to make agriculture more sustainable by eliminating waste from the production process.
Using off-the-shelf technology and innovative economics, lightweight helium balloons have started carrying remote-controlled laboratories to the edge of space and back, offering the business case for new types of science missions.
Floating research laboratories are reaching the fringes of space.
Automated and connected devices can save lives.
EU firms should be brought within ‘innovation ecosystems’ to develop breakthrough technology, according to Prof. Luke Georghiou.
