Mexican satellite launch grounded for engineering review

The launch of a Boeing-built Mexican communications satellite on a Proton rocket has been postponed after engineers discovered an anomaly on a similar spacecraft. The Proton rocket was supposed to blast off Tuesday from the Baikonur Cosmodrome in Kazakhstan. The Centenario satellite, also known as Mexsat 1, remains safely perched atop the 19-story rocket at the launch pad, according to International Launch Services, the U.S.-based firm which manages commercial Proton missions. ILS said in a statement Monday that the launch was “postponed in order to investigate an anomalous condition discovered on another spacecraft and to re-confirm the flight worthiness of the Centenario satellite.” More
