Juno: close, but no science

JunoNASA’s Juno space probe makes a third close swing past Jupiter, but engineering problems make it a blind pass: concerns over stuck valves in the engine leads ground controllers to cancel a planned engine burn to shorten the length of Juno’s orbit, and then mere hours before its latest close pass, Juno goes into a safe mode which shuts down all instruments and cameras pending intervention from Earth. Juno principal investigator Scott Bolton assures that Juno could, theoretically, complete its mission with longer, unadjusted orbits if need be; Juno’s next close pass by Jupiter is expected to happen in December, impacting all future events in the mission plan.
