Photos: Atlas 5 rocket aims for International Space Station

Rocket Lab canceled a launch attempt Wednesday in New Zealand to evaluate unexpected sensor data, postponing a mission that will deliver 10 small commercial Earth-imaging satellites to orbit.

China added two more satellites to the country’s Beidou navigation fleet — an analog to the U.S. military’s GPS network — with a successful Long March 3B rocket launch Sunday.

Desperately needing a successful deployment to modernize the communications infrastructure for its citizens, Mexico is counting on the Atlas 5 rocket to safely launch a new satellite Friday.
