The European Space Agency (ESA) is Europe’s gateway to space. Its mission is to shape the development of Europe’s space capability and ensure that investment in space continues to deliver benefits to the citizens of Europe and the world.

The water drunk by astronauts on the International Space Station is recycled by up to 80% from their sweat, urine and other sources. Recycling reduces the number of supply missions needed to run the Station, and building a self-sufficient spacecraft will be necessary for future mission farther from our planet.
Flight surgeons and astronauts closely monitor the quality of the drinking water and the Aquapad experiment that ESA astronaut Thomas Pesquet will run in space aims to simplify the regular testing.
Aquapad is a new approach developed by France’s CNES space agency and French diagnostic company bioMérieux: paper impregnated with powdered growth medium creates a 3D petri dish. When water is added, the microbes form coloured spots revealing their locations.
Although developed for space, the technology behind Aquapad is clearly useful on Earth. For example, in disaster areas, where water could be contaminated, a quick picture and calculation are cheaper and faster than sending samples to a laboratory.
