That is why they have known the results after one and half day. Kepler spacecraft went into Emergency mode one and half day earlier.

They say it happened 1.5 days before but then they go on to say
"At such a distance, it takes 13 minutes for data to be sent or received between the spacecraft and NASA’s ground stations."

if there is a 13 min delay then why didnt Kepler send notification on its own rather than them finding this in a "routine communications check" 1.5 days after it occured. seems like there would have to be some further problems going on. cant imagine them not designing it to send an alert when something like this happens right away.

@wannabe - there definitely seems to be some kind of fault warning malfunction, or maybe they aren't carrying out enough routine checks. I'd suspect it's the former.
