Bad weather at Kennedy Space Center in Florida forced NASA to put off the first test flight of the new rocket that could someday replace the space shuttle.
The tall, skinny white rocket called Ares I-X is an experimental version of the Ares I rocket that's part of NASA's effort to build new space vehicles that could someday get a capsule of astronauts into orbit and then onto the moon.
The unmanned test flight was originally targeted for 8 a.m. EDT. But winds and clouds over the launch site forced mission managers to reset the target launch time again and again, hoping for better weather. They finally decided to stand down until the next launch window on Wednesday morning.
The test flight is coming less than a week after a panel of experts convened by the White House suggested the possible cancellation of the Ares I program. Because of budget cuts and technological issues, the panel said, the rocket probably won't be ready until 2017.
