After gearing up for the space agency's much-hyped mission to hurl two spacecraft into the moon, the public turned away from the sky Friday anything but dazzled. Photos and video of the impact showed little more than a fuzzy white flash. In social media and live television coverage, many people were disappointed at the lack of spectacle. One person even joked that someone hit the pause button in mission control. Yet scientists involved in the project were downright gleeful. Sure, there were no immediate pictures of spewing plumes of lunar dust that could contain water, but, they say, there was something more important: chemical signatures in light waves. That's the real bonanza, not pictures of geyser-like eruptions of debris, the scientists said. The mission was executed for “a scientific purpose, not to put on a fireworks display for the public,” said space consultant Alan Stern, a former NASA associate administrator for science. Scientists said the public expected too much. The public groused as if NASA delivered too little. The divide was as big as a crater. “We've been brainwashed by Hollywood to expect the money shot, like ‘Deep Impact' or when Bruce Willis saves us from a comet,” said physicist and television host Michio Kaku, who was not part of the mission. “Science is not done that way.” But Kaku and other experts also faulted NASA for overhyping the mission, not being honest with the public about the images being a longshot. “They should have put Steven Spielberg in charge,” Kaku said. NASA's LCROSS mission _ short for Lunar Crater Observation and Sensing Satellite and pronounced L-Cross – had all the makings of a blockbuster. Its main goal was to look for some form of water on the moon – something that could still turn up in those light wave chemical signatures. A preliminary review of data from the Hubble Space Telescope indicated no signs of water in the debris viewed from the blast, NASA said late Friday, but added that more study was needed. And water on the moon could change NASA's troubled plans for space exploration. It would make revisiting and putting a base on the moon far cheaper because the moon's water could be used, Kaku said. It was relatively cheap and last-minute by NASA standards: Just $79 million, in about three years. It was elegant in its simplicity. An empty rocket hull that would normally be space junk remained attached to the plucky little LCROSS until pulling away Thursday night.
