Europe’s Arian 5 ES rocket successfully launched a quadruplet of Galileo positioning, navigation, and timing satellites into the medium-Earth orbit on Thursday, November 17, Space News reports.
Europe is preparing for the Nov. 17 launch of the Galileo navigation satellites. The quadruple satellites will be flying atop an Ariane 5 rocket from French Guiana spaceport.
A European Space Agency (ESA) Galileo satellite that had slipped into an erroneous orbit soon after deployment last August is reportedly back on its feet, so to speak. The unmanned craft sent its first navigation signal in space on Saturday 29 November 2014 after reaching a new target orbit.
A set of satellites recently launched by the European Space Agency aren't where they were planned to be, according to officials. An investigation into the matter in ongoing.
