It’s non every 24-hour interval that researchers at UC San Diego tin enlist a NASA astronaut to tweak their experimental set-up, but when duty calls, Scott Kelly is at the ready.
The astronaut, who returned to populace 2 weeks agone next a one-year mission aboard the International Space Station, made crucial adjustments during his mission to an experiment led past times Forman Williams, a professor of mechanical together with aerospace technology scientific discipline at the University of California, San Diego. Williams’ Flame Extinguishment Experiment (FLEX) report – 1 of several microgravity experiments existence run on the ISS’s Destiny Laboratory – is an attempt to larn to a greater extent than nearly so-called cool-burning flames, which could Pb to the production of safer spacecraft equally good equally cleaner, to a greater extent than efficient engines for vehicles dorsum on earth.
Kelly spent 2 consecutive days configuring exam hardware to perform exam points for the FLEX system. He besides replaced needles, a fiber arm, igniter tips together with reservoirs inward back upwards of the experiments.
All the FLEX experiments accept house inward the ISS’s Multiuser Droplet Combustion Apparatus, which tin generate together with ignite droplets from dissimilar fuels inward dissimilar atmospheric conditions. The bedroom is crammed alongside sensors together with equipped alongside video cameras that tape experiments. It’s located within an experimental facility called the Combustion Integrated Rack, which is roughly the size of a 5.5-foot bookcase, weighs closed to 560 lbs together with records the information for transmission dorsum to Earth.
Researchers believe that cool flames – which were discovered during an experiment aboard the ISS inward 2014 – are the trial of simple chemic reactions that exercise non cause got the fourth dimension to develop closed to burning fuel droplets on earth, where they tin alone be for a real curt catamenia of time. The FLEX report seeks to larn to a greater extent than nearly how chop-chop fuel burns, the weather condition required for soot to form, together with how mixtures of fuels evaporate earlier burning. The microgravity surround of the ISS, where at that spot is no buoyancy, makes it possible to supply a sufficient amount of exam fourth dimension required to back upwards the chemic procedure that creates cool flames.
