Q&A with Mark Mulqueen, Boeing’s space station program manager

NASA has announced a one-day delay in SpaceX’s next cargo launch until Wednesday to allow time for ground teams to replace moldy food bars meant for 40 mice heading for the International Space Station as part of a biological research experiment, denying the launch company a chance at two Falcon 9 missions on back-to-back days.

Russian investigators have traced the cause of a dramatic Oct. 11 Soyuz launch abort to a “deformed” sensor in a system that controlled the separation of a strap-on first-stage booster from the rocket’s central core stage, triggering a dramatic emergency escape for the Russian mission commander and his NASA co-pilot, senior managers said Thursday.

A Russian Proton rocket blasted off from Kazakhstan on Friday on a critical launch aiming to complete deployment of a major multibillion-dollar global communications network for London-based Inmarsat. Liftoff occurred at 1144 GMT (7:44 a.m. EDT), but it will take more than 15 hours to put the satellite in the correct orbit.
