VANDENBERG AFB, CALIF. -- Technicians ready the Pegasus XL rocket, the vehicle that will launch the High Energy Solar Spectroscopic Imager (HESSI), for flight to Florida. The primary mission of HESSI is to explore the basic physics of particle acceleration and energy release in solar flares. The launch of PegasusXL/HESSI is scheduled for Feb. 5, 2002, from beneath an Orbital Sciences Corp. L-1011 aircraft over the Atlantic Ocean KSC-02pd0087

VANDENBERG AIR FORCE BASE, CALIF. - At Vandenberg Air Force Base, Calif., the Pegasus launch vehicle is moved toward its hangar. The Pegasus will carry the SciSat-1 spacecraft in a 400-mile-high polar orbit to investigate processes that control the distribution of ozone in the upper atmosphere. The data from the satellite will provide Canadian and international scientists with improved measurements relating to global ozone processes and help policymakers assess existing environmental policy and develop protective measures for improving the health of our atmosphere, preventing further ozone depletion. The mission is designed to last two years.

KENNEDY SPACE CENTER, FLA. - At Vandenberg Air Force Base in California, the DART (Demonstration for Autonomous Rendezvous Technology) flight demonstrator is revealed after its protective cover has been removed. The spacecraft was developed to prove technologies for locating and maneuvering near an orbiting satellite. Future applications of technologies developed by the DART project will benefit the nation in future space-vehicle systems development requiring in-space assembly, services or other autonomous rendezvous operations. Designed and developed for NASA by Orbital Sciences Corporation in Dulles, Va., the DART spacecraft will be launched on a Pegasus launch vehicle. At about 40,000 feet over the Pacific Ocean, the Pegasus will be released from Orbital’s Stargazer L-1011 aircraft, fire its rocket motors and boost DART into a polar orbit approximately 472 miles by 479 miles. Once in orbit, DART will rendezvous with a target satellite, the Multiple Paths, Beyond-Line-of-Site Communications satellite, also built by Orbital Sciences. DART will then perform several close proximity operations, such as moving toward and away from the satellite using navigation data provided by onboard sensors. DART is scheduled for launch no earlier than Oct. 18. KSC-04pd1593

KENNEDY SPACE CENTER, FLA. - An artist’s conception of the autonomous Demonstration for Autonomous Rendezvous (DART) spacecraft as it approaches the Multiple Paths, Beyond-Line-of-Site Communications (MUBLCOM) satellite. NASA is testing the DART as a docking system for next generation vehicles to guide spacecraft carrying cargo or equipment to the International Space Station, or retrieving or servicing satellites in orbit. Before the new system can be implemented on piloted spacecraft, it has to be tested in space. The computer-guided DART is equipped with an Advanced Video Guidance Sensor and a Global Positioning System that can receive signals from other spacecraft to allow DART to move within 330 feet of the target. DART is scheduled to launch from Vandenberg Air Force Base in California no earlier than Oct. 18. It will be released from a Pegasus XL launch vehicle carried aloft by an Orbital Sciences Corporation aircraft. The fourth stage of the Pegasus rocket will remain attached as an integral part of the spacecraft, allowing it to maneuver in space. Once in orbit, DART will race toward the target, the MUBLCOM satellite, for a rendezvous. KSC-04pd1684

DART is scheduled to launch from Vandenberg Air Force Base in California no earlier than Oct. 18. It will be released from a Pegasus XL launch vehicle carried aloft by an Orbital Sciences Corporation aircraft. The fourth stage of the Pegasus rocket will remain attached as an integral part of the spacecraft, allowing it to maneuver in space. Once in orbit, DART will race toward the target, the MUBLCOM satellite, for a rendezvous. KSC-04pd1685

KENNEDY SPACE CENTER, FLA. - An artist’s conception of the autonomous Demonstration for Autonomous Rendezvous (DART) spacecraft as it approaches the Multiple Paths, Beyond-Line-of-Site Communications (MUBLCOM) satellite. NASA is testing the DART as a docking system for next generation vehicles to guide spacecraft carrying cargo or equipment to the International Space Station, or retrieving or servicing satellites in orbit.

KENNEDY SPACE CENTER, FLA. - At Vandenberg Air Force Base in California, the Demonstration of Autonomous Rendezvous Technology (DART) spacecraft is prepared for rotation from horizontal to vertical. It will be lifted onto a test stand for launch processing activities. The spacecraft was developed for NASA by Orbital Sciences Corporation in Dulles, Va., to prove technologies for locating and maneuvering near an orbiting satellite. DART will be launched on a Pegasus launch vehicle. At about 40,000 feet over the Pacific Ocean, the Pegasus will be released from Orbital’s Stargazer L-1011 aircraft, fire its rocket motors and boost DART into a polar orbit approximately 472 miles by 479 miles. Once in orbit, DART will rendezvous with a target satellite, the Multiple Paths, Beyond-Line-of-Site Communications satellite, also built by Orbital Sciences. DART will then perform several close proximity operations, such as moving toward and away from the satellite using navigation data provided by onboard sensors. DART is scheduled for launch no earlier than Oct. 18. KSC-04pd1635

VANDENBERG AIR FORCE BASE, Calif. — In the Orbital Sciences Building 836 at Vandenberg Air Force Base in California, workers lower the second satellite onto the payload support structure. Three micro-satellites are being mounted on a payload support structure. The three satellites make up the Space Technology 5 spacecraft, called ST5, and will be launched by a Pegasus XL rocket. The satellites contain miniaturized redundant components and technologies. Each will validate New Millennium Program selected technologies, such as the Cold Gas Micro-Thruster and X-Band Transponder Communication System. After deployment from the Pegasus, the micro-satellites will be positioned in a “string of pearls” constellation that demonstrates the ability to position them to perform simultaneous multi-point measurements of the magnetic field using highly sensitive magnetometers. The data will help scientists understand and map the intensity and direction of the Earth’s magnetic field, its relation to space weather events, and affects on our planet. With such missions, NASA hopes to improve scientists’ ability to accurately forecast space weather and minimize its harmful effects on space- and ground-based systems. Launch of ST5 is scheduled for Feb. 28 from Vandenberg Air Force Base. KSC-06pd0165

The three satellites that make up the Space Technology 5 spacecraft, called ST5, will be launched by a Pegasus XL rocket. The satellites contain miniaturized redundant components and technologies. Each will validate New Millennium Program selected technologies, such as the Cold Gas Micro-Thruster and X-Band Transponder Communication System. After deployment from the Pegasus, the micro-satellites will be positioned in a “string of pearls” constellation that demonstrates the ability to position them to perform simultaneous multi-point measurements of the magnetic field using highly sensitive magnetometers. The data will help scientists understand and map the intensity and direction of the Earth’s magnetic field, its relation to space weather events, and affects on our planet. With such missions, NASA hopes to improve scientists’ ability to accurately forecast space weather and minimize its harmful effects on space- and ground-based systems. Launch of ST5 is scheduled for Feb. 28 from Vandenberg Air Force Base. KSC-06pd0163

VANDENBERG AIR FORCE BASE, Calif. — Inside Orbital Sciences’ Building 1555 at Vandenberg Air Force Base in California, the wrapped Space Technology 5 (ST5) spacecraft is revealed after removal of the shipping container. ST5 will be launched by a Pegasus XL rocket. The satellites contain miniaturized redundant components and technologies. Each will validate New Millennium Program selected technologies, such as the Cold Gas Micro-Thruster and X-Band Transponder Communication System. After deployment from the Pegasus, the micro-satellites will be positioned in a “string of pearls” constellation that demonstrates the ability to position them to perform simultaneous multi-point measurements of the magnetic field using highly sensitive magnetometers. The data will help scientists understand and map the intensity and direction of the Earth’s magnetic field, its relation to space weather events, and affects on our planet. With such missions, NASA hopes to improve scientists’ ability to accurately forecast space weather and minimize its harmful effects on space- and ground-based systems.
