With a claimed data throughput of 140Gbps, the Viasat-1 can transmit more data than all the other commercial communications satellites broadcasting to the US and Canada combined.
It was launched by a Russian Proton rocket from the Baikonur Cosmodrome in Kazakhstan yesterday on behalf of US satellite broadband company Viasat, which will use it to power the essential YouTube downloading needs of rural American subscribers of its Wildblue Communications ISP.
It beats the previous fattest satellite broadcaster, the European Eutelsat Ka-Sat, which managed a total throughput of 70Gbps. And yes, Gbps stands for "Gigabytes per second."[BBC]
