NASA's new moon rocket arrived at the launch pad Wednesday ahead of its debut flight in less than two weeks. The 322-foot rocket emerged from its mammoth hangar late Tuesday night, drawing crowds of Kennedy Space Center workers, many of whom were not yet born when NASA sent astronauts to the moon a half-century ago. It took nearly 10 hours for the rocket to make the four-mile trip to the pad, pulling up at sunrise. NASA is aiming for an Aug. 29 liftoff for the lunar test flight, the AP reports. No one will be inside the crew capsule atop the rocket, just three mannequins swarming with sensors to measure radiation and vibration.
The capsule will fly around the moon in a distant orbit for a couple of weeks before heading back for a splashdown in the Pacific. The entire flight should last six weeks. The flight is the first moonshot in NASA's Artemis program. The space agency is aiming for a lunar-orbiting flight with astronauts in two years and a lunar landing by a human crew as early as 2025. That's much later than NASA anticipated when it established the program more than a decade ago, as the space shuttle fleet retired. The years of delays have added billions of dollars to the cost. "Now for the first time since 1972, we're going to be launching a rocket that’s designed for deep space," NASA's rocket program manager, John Honeycutt, said recently.
NASA's new SLS moon rocket, short for Space Launch System, is 41 feet shorter than the Saturn V rockets used during Apollo a half-century ago. But it's more powerful, using a core stage and twin strap-on boosters, similar to the ones used for the space shuttles. "When you look at the rocket, it almost looks retro. It looks like we're looking back toward the Saturn V," NASA Administrator Bill Nelson told reporters earlier this month. "But it's a totally different, new, highly sophisticated, more sophisticated rocket and spacecraft." This was the rocket's third trip to the pad. A countdown test in April was marred by fuel leaks and other equipment trouble, forcing NASA to return the rocket to the hangar for repairs. The dress rehearsal was repeated at the pad in June, with improved results. "I want to underscore that this is a test flight," Nelson said. "It's just the beginning."
