Carrying water to space is extremely costly, thus recycling of it should be improved. On Earth, water management is also essential, for example to control humidity in buildings and where fresh water is scarce. 果冻影院 Centre for Nature Inspired Engineering (CNIE) PhD candidate听Malica Schmidt听draws lessons from nature to develop multi-functional surfaces to enhance water capture for reuse, combined with other desirable properties. Malica is supported by an EPSRC National Productivity Investment Fund studentship and is a CNIE PhD candidate co-advised by Prof Marc-Olivier Coppens听(果冻影院 Chemical Engineering) and Prof Marcos Cruz听(The Bartlett).

The novel Nature-Inspired, Multi-Functional Surfaces (NIMFS), were designed to absorb excess atmospheric moisture produced by astronauts鈥� indoors activities and transport it passively to improve existing and future life support systems on the International Space Station (ISS) and听missions to the Moon, Mars, and beyond. Previous ground-based experiments in the CNIE鈥檚 labs on designs manufactured using a Nanoscribe 鈥�3D microprinter鈥�, suggest increased performance of NIMFS in microgravity. Parabolic flights, on which microgravity is achieved during each apex of the parabola, allow this hypothesis to be tested.听听

From 16听to 24听September 2020, the听German Aerospace Center Space Administration听(DLR, Deutsches Zentrum f眉r Luft- und听Raumfahrt) organised the听35th Parabolic Flight Campaign听with the participation of eight teams during three flight days in Paderborn-Lippstadt Airport. Among them was the physical science experiment of Malica in collaboration with two departments from 果冻影院, the DLR, the听European Space Agency听(ESA), and the听Karlsruher Institut f眉r Technologie听(KIT).听

In these flights, microgravity is achieved by flying a series of 31 parabolas per day in the Airbus A310 Zero-G, owned by the French company听Novespace. During these parabolas, Malica and the experiment experienced 1.8 g during pull up of the airplane鈥檚 nose to 50 degrees, 22 seconds of microgravity when the pilots throttled the engine back, and a second 1.8 g phase when the plane pulled听down, before it went back to听steady flight.

For Malica and her team, this flight was the first of a series of experiments in microgravity, which may be used as a bridge to the ISS. It was also the first DLR flight during the Covid-19 pandemic. The originally scheduled flight in Bordeaux, France, had been postponed last-minute, but a later campaign flying from Paderborn materialised. In a feat of resilience and endurance, Malica, the team, and the other researchers had to deal with difficult, volatile conditions as institutions and labs were closed, but they took the opportunity of partial (re-)openings to make the impossible happen.

Apart from the synthesis of the NIMFS at 果冻影院 CNIE and KIT, Malica designed and assembled a flight-proof setup, including components manufactured with exceptional assistance from workshops and research technicians both at 果冻影院's The Bartlett, and at the DLR, with the latter听administration鈥檚 support. At last, months of preparation were put to good use for Malica to get the times right to carry out experiments with military precision, socially distanced under the challenging conditions of the parabolic flight rollercoaster. A total of 35 minutes of microgravity research has been accumulated, which is currently being analysed.

The Centre for Nature Inspired Engineering at 果冻影院 is a cross-disciplinary centre based within 果冻影院 Chemical Engineering, which draws lessons from nature to engineer innovative solutions to our grand challenges in energy, water, materials, health, and living space. Research is aligned to the UN Sustainable Development Goals, the UK Industrial Strategy and 果冻影院鈥檚 Grand Challenge on Transformative Technology.听
