Just heard this news

A Japanese communication sat was supposed to launch from Baikonaur today

Looks like Japan got tired of trying to launch their payloads on the costly H-2 which had a number of failed launches so they went for the less costly Russian option.

Major setback for the Russians, Proton just exploded (a proton failure may have ISS fallout).
and More bad luck for Japan :(

I don't know of any additional Proton launches scheduled for the ISS so there should be little impact. Your thread title is a bit misleading. It suggests that the satellite exploded, causing the Proton to fail. From what I've read, the Proton second stage engines failed to ignite (sounds like a turbopump failure since the Proton uses hypergolic propellants). The satellite was fine up until the destruct signal or ground impact.
