International Launch Services, facing headwinds in a commercial launch market now largely shaped by billionaires and satellite miniaturization, has touted a new relationship with the Russian space agency and Glavkosmos as a means to drive down Proton rocket prices, make Russian space industry more friendly to the commercial market, and diversify its offerings.
