4 billion miles: One tank of fuel
When the European Space Agency’s (ESA) Rosetta space probe arrived at Comet 67P/Churyumov-Gerasimenko it had been travelling for 10 years and completed 4 billion miles on just one tank of fuel. Kistler pressure sensors monitored the fuel consumption continuously to ensure that Rosetta arrived at its destination with enough fuel to make the final corrections necessary to put the probe into orbit.
