Past Projects

Remote Agent
The first artificial intelligence control system to control a spacecraft without human supervision. Flown aboard NASA’s Deep Space 1 in 1999, Remote Agent successfully demonstrated the ability to plan onboard activities and correctly diagnose and respond to simulated faults in spacecraft components. Autonomous control will enable future spacecraft to operate at greater distances from Earth, and to carry out more sophisticated science-gathering activities in deep space.

Mars Pathfinder Terrain Modeling
Provided mission scientists at the Jet Propulsion Laboratory (JPL) with 3D digital topographic models and an advanced interface for interaction with the virtual environment of the Martian surface during the Mars Pathfinder mission. Thanks to the photographic realism of the terrain models, scientists were able to learn more quickly about the Pathfinder landing site than they would have from a static view of the rock field that surrounded the lander. The virtual reality aspect of the display allowed them to move around the field, even to project a bird's eye view from above it. Moreover, 3D measurements of positions, distances, and angles were easily extracted from the topographic models, which provided valuable tools for science analysis and mission planning.

Databus Analysis Tool
A joint project between JSC's International Space Station Program and Code TI's Intelligent Mobile Technologies group. The DAT is a diagnostic tool consisting of both hardware and software running on a Shuttle computer that allows detailed on-orbit monitoring and logging of all 1553B avionics bus messages, the nerve system of the Space Station. The DAT was first flown aboard the STS-88 mission in December 1998, the first International Space Station assembly flight, which accomplished the on-orbit integration of the Zarya and Unity modules.

Principal Investigator (PI)-in-a-Box
An expert system designed to assist astronauts performing vestibular experiments on the Spacelab flights SLS-1 and SLS-2, and the Neurolab Sleep Experiment on STS-90 in April 1998.

SHOOT: Superfluid Helium On-Orbit Transfer
Software tools developed to support the monitoring and control of a Shuttle payload bay cryogenics experiment that successfully flew on the STS-57 in 1993. The SHOOT experiment was the first use of an expert system to teleoperate the payload from a remote ground station.

AutoClass
A program which automatically finds unexpected classifications, or groupings of like things, in data, such as new classes of infrared stars in the IRAS Low Resolution Spectral catalogue, and classes of proteins and introns in DNA/protein sequence data. AutoClass won a 1992 NASA Space Act Award.

The Wireless Network Experiment (WNE)
The first test of a wireless client-sever network in the space environment. The Mir WNE was launched by the Space Shuttle flight STS-74 in November 1995 and successfully conducted aboard the Space Shuttle Atlantis and the Mir Space Station in March 1996 during STS-76.

Surface Movement Advisor (SMA)
An airport ground traffic control system currently running at Atlanta Hartsfield International Airport. A 1997 study by the FAA conservatively estimated a cost saving of $20 million as a result of increased efficiency due to SMA technology.

The Ground Processing Scheduling System (GPSS)
A successful development of a Scheduler/Flow Control system for Space Shuttle Ground Processing at Kennedy Space Center to refurbish Space Shuttles between missions. The GPSS won the largest NASA Space Act award ever and is an outstanding commercial technology spin-off.

Clarissa
An experimental voice-enabled procedure reader, developed during a three-year project starting in early 2002, which enables astronauts on the International Space Station (ISS) to navigate complex procedures using only spoken input and output. This offers significant advantages for carrying out hands- and eyes-busy tasks in the challenging environment of microgravity. Clarissa has a vocabulary of about 260 words and supports about 75 different commands, including reading steps, scrolling forwards or backwards in the procedure, moving to an arbitrary new step, reviewing non-current steps, adding or removing voice notes, displaying pictures and setting alarms or timers. Clarissa was the first spoken dialogue system to be deployed in space. It was delivered to the ISS on Christmas Day, 2004, and it was successfully tested by Astronaut John Phillips on June 27, 2005.

Regulus
An Open Source platform used for building complex spoken command grammars, developed since 2001 by a consortium whose main partners are NASA Ames, the University of Geneva, and Fluency Voice Technology. The central idea is to develop a single English grammar, based on general linguistic principles, from which one can derive application-specific command grammars using example-based methods. Regulus has been used to build command grammars for Clarissa and several other major projects, including a medical speech translator and a speech-enabled home control system.
