Rogue Soyuz Rocket Engine Firings Are No Big Deal

NASA ISS On-Orbit Status 9 June 2015

"Today at 10:27 a.m. Central time during the routine testing of communications systems between the Soyuz TMA-15M spacecraft and the International Space Station (ISS), Soyuz thrusters activated inadvertently which led to a slight change in the orientation of the ISS. Actions were immediately taken to reorient the ISS. There was no threat to the crew or the station itself, and the issue will have no impact to a nominal return to Earth of the Soyuz TMA-15M on Thursday. Roscosmos specialists are determining the cause of the incident. Once more information is known, additional information will be provided."

Keith's note: Hmmm ... rocket engines on a spacecraft just fire for some unknown reason, alter the ISS orientation such that contingency measures need to be taken and ... that's it: stay tuned? When I worked at NASA something like this in a safety review would have justifiably been a cosmic issue of epic proportions. Not any more, it would seem. I guess there will be some telecons and some Powerpoint slides.
