NASA and DLR to conduct joint flight tests on alternative fuel emissions with focus on ice crystals

Green Car Congress

The focus will be on alternative fuel emissions and the characterisation of ice crystals in condensation trails (contrails), using biofuel as an example. The planned research flights are intended to determine particle emissions and how they affect cloud formation through contrails, thus investigating their impact on the climate.
