Si parla molto sui mass media, da parecchie settimane, di un articolo scientifico peer reviewed in arrivo in cui la NASA stessa confermerebbe il funzionamento dell'EmDrive, il motore ritenuto "impossibile" in quanto sembrerebbe violare il principio di azione e reazione (conservazione della quantità di moto) di Newton. Un motore siffatto potrebbe ridurre l'ordine di grandezza di un viaggio su Marte da un anno a un paio di mesi, per cominciare, poi si sa: quando nasce una nuova tecnologia, strada facendo, i margini di sviluppo possono superare ogni aspettativa.
Abstract. A vacuum test campaign evaluating the impulsive thrust performance of a tapered radio-frequency test article excited in the transverse magnitude 212 mode at 1937 MHz has been completed. The test campaign consisted of a forward thrust phase and reverse thrust phase at less than 8 × 10−6 torr vacuum with power scans at 40, 60, and 80W. The test campaign included a null thrust test effort to identify any mundane sources of impulsive thrust; however, none were identified. Thrust data from forward, reverse, and null suggested that the system was consistently performing with a thrust-to-power ratio of 1.2 0.1 mN∕kW.
