CAPE CANAVERAL, Fla. (AP) ? NASA’s newest moon probes are still on Earth.
The launch countdown got all the way down to the four-minute mark Saturday morning. But high wind prevented the unmanned rocket from blasting off on the day’s first opportunity. NASA has one more chance to get the twin spacecraft flying Saturday at 9:08 a.m. Otherwise, that’s it until Sunday.
This is the third launch delay for the $496 million Grail mission. Thursday’s try was put off by high wind. Rocket concerns spoiled Friday’s attempt.
The twin Grail spacecraft will circle the moon and measure its gravity.
