BAIKONUR COSMODROME, Kazakhstan, April 27, 2015-The launch of a Proton launch vehicle with the Centenario satellite was postponed in order to investigate an anomalous condition discovered on another spacecraft and to re-confirm the flight worthiness of the Centenario satellite.

The vehicle and satellite remain in a safe configuration at the launch site.

The satellite was built by Boeing Satellite Systems International for the Mexican government’s Ministry of Communications and Transportation, the Secretaria de Comunicaciones y Transportes (SCT).
