Keeping astronauts alive – and improving wine

17 OCT. 2012 1539

Astronauts on a long-duration space mission would need tonnes of food, water and oxygen with them to stay alive – if they rely on current life support technologies. But ESA’s Micro-Ecological Life Support System Alternative (MELiSSA) pilot plant at the University Autònoma of Barcelona is targeting the creation of a closed-loop life-support system with close to 100% efficiency: all food is grown and water and air recycled. At the moment, a ‘crew’ of rats are being kept alive; one element of the international long-term MELiSSA effort, coordinated by ESA. Terrestrial spin-offs include improved water purification and process control for wine-making.

Self-steering rover for alien worlds

Six intense months of work culminated in a self-steering rover charting its own course through Chile’s Mars-like Atacama Desert. Innovative R&D projects can be run in innovative ways: ESA’s long-running StarTiger initiative gathers together a highly able team and sets them a challenge, in this case to develop methods for a long-range rover to navigate its way across many kilometres of an alien planet’s surface. Codenamed ‘Seeker’, the project was led and hosted for ESA by the UK’s Rutherford Appleton Laboratory.
