The Lunar Prospector spacecraft that >discovered water on the Moon, developed by NASA Ames Research Center, >Moffett Field, CA, was a runner-up in that category, and another Ames >project, experimental "smart airplane" software was a finalist in the >Transportation category. > >The smart plane software which can help pilots safely land aircraft that >have suffered major failures was flight tested on a modified F-15 aircraft. >Each sixth of a second, a damaged aircraft's computer can "relearn" to fly >the aircraft using special neural network "controller" software. Without >the smart software, severe problems such as partially destroyed wings, >major fuselage tears or sensor failures can greatly alter how an airplane >handles, and the aircraft might respond oddly or pilots' controls may not >work properly. > >"We were fascinated when we saw each others' inventions during the Awards >events," said Dr. Chuck Jorgensen, a NASA Ames scientist who leads the >smart plane software effort. "I felt very honored when I saw how many >amazing inventions competed." > >In the Exploration category, "To the Moon, Cheaply," the Lunar Prospector >spacecraft project, was runner-up to the Revolutionary Rocket. Lunar >Prospector exemplifies NASA's new way of doing business, having set new >standards in cost containment and schedule for a NASA exploration mission. > >Developed in less than three years at a total cost of $63 million, Lunar >Prospector provided evidence that water ice exists in the permanently >shadowed craters of the lunar polar regions. Prospector also yielded data >that have led to the development of complete gravity maps of the Moon, maps >of location and extent of key minerals and other elements, and evidence >concerning tectonic and volcanic activity. >-more- >-2- > >"I want to add my congratulations to all those who are working tirelessly >to develop new innovations and technologies to meet the needs of people >worldwide in the next century," Vice President Al Gore wrote in a letter to >awards ceremony attendees.

The >Boeing Company's Phantom Works division, St. Louis, MO, integrated the NASA >Ames neural network software into the F-15 test aircraft. Jorgensen is the >principal investigator for the four-year Intelligent Flight Controller >Program at Ames. > >"Neural net software learns by observing 'patterns' in the real world and >learning to take new actions in response to different patterns," Jorgensen >said. > > The software gets speed, direction and force data from sensors on >the aircraft. The aircraft's computer compares the pattern of what is >actually happening to the aircraft with a pattern showing how the airplane >should fly. If there is a mismatch, the computer software, which contains >a dozen basic aeronautical equations, or "behavior patterns" that define >how airplanes fly, makes the system work with a "new pattern," if it is >feasible. > >"If sensor data show that a pattern is not being followed, and the airplane >is turning too abruptly, the airplane's neural network can rapidly learn to >assist the pilot. It does this by helping the pilot to use the stick, >flaps, rudders and other control surfaces in ways that may be very >unconventional, but possibly successful," said Jorgensen. >-end- > > To receive Ames press releases via email, send an email with the >word "subscribe" in subject line to: >ames-releases-request@lists.arc.nasa.gov >To unsubscribe, send an email to: ames-releases-request@lists.arc.nasa.gov >with "unsubscribe" in subject line.
