U.S. Space Agency Launches Lunar Satellites
The U.S. space agency, NASA, has launched its twin GRAIL lunar satellites meant to examine the gravitational field and internal structure of the moon.
The launch of the Gravity Recovery and Interior Laboratory, or GRAIL, followed several weather-related delays Thursday and Friday. Saturday’s launch took place in the second and final of two “launch windows” that NASA had announced for the day.
High winds scrubbed Thursday’s first launch effort. NASA officials say they rescheduled the Friday attempt when technicians asked for more time to analyze the condition of the Delta II launch rocket.
