The launch of Orbital Sciences

The launch of Orbital Sciences’ Antares rocket carrying its Cygnus cargo spacecraft has been scrubbed. The range remained red because of a boat down range in the trajectory Antares would have flown had it lifted off.

United Space Alliance technician Don Pataky

United Space Alliance technician Don Pataky repairs hail-inflicted damage in the foam insulation on the external tank of Space Shuttle Discovery. The Shuttle was rolled back from Pad 39B to the Vehicle Assemby Building for repairs because access to all of the damaged areas was not possible at the pad. The work is expected to take two to three days, allowing Discovery to roll back to the pad late this week for launch of mission STS-96, the 94th launch in the Space Shuttle Program. Liftoff will occur no earlier than May 27. STS-96 is a logistics and resupply mission for the International Space Station, carrying such payloads as a Russian crane, the Strela; a U.S.-built crane; the Spacehab Oceaneering Space System Box (SHOSS), a logistics items carrier; and STARSHINE, a student-shared experiment. 05/18/1999

In the Vehicle Assembly Building, Ken Strite, NASA Quality Control, inspects the connection between Space Shuttle Discovery and the external tank that will be used to launch mission STS-103 in early December. This 10-day mission is designed to replace aging parts on the nine-year-old Hubble Space Telescope and to upgrade some of its functioning systems. During the flight, the astronaut crew will replace all six of the observatory's gyroscopes, a fine guidance sensor, its main computer, and other equipment. 11/05/1999

The orbiter Discovery rolls along the tow-way to the Vehicle Assembly

The orbiter Discovery rolls along the tow-way to the Vehicle Assembly Building where it will be mated with an external tank and solid rocket boosters for its launch on mission STS-103. The launch date is currently under review for early December. STS-103, the third Hubble Space Telescope servicing mission, is a "call-up" due to the need to replace portions of the pointing system, the gyros, which have begun to fail on the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. The gyroscopes allow the telescope to point at stars, galaxies and planets. The STS-103 crew will also be replacing a Fine Guidance Sensor and an older computer with a new enhanced model, an older data tape recorder with a solid-state digital recorder, a failed spare transmitter with a new one, and degraded insulation on the telescope with new thermal insulation. The crew will also install a Battery Voltage/Temperature Improvement Kit to protect the spacecraft batteries from overcharging and overheating when the telescope goes into a safe mode. 11/04/1999

 

 

 

 

 

 

 

 

 

Space Shuttle Discovery makes the turn toward Launch Pad 39B

Space Shuttle Discovery makes the turn toward Launch Pad 39B on its trek atop the mobile launcher platform and crawler transporter. Once at the pad, the orbiter, external tank and solid rocket boosters will undergo final preparations for the STS-103 launch targeted for Dec. 6, 1999, at 2:37 a.m. EST. The mission is a "call-up" due to the need to replace and repair portions of the Hubble Space Telescope. Although Hubble is operating normally and conducting its scientific observations, only three of its six gyroscopes are working properly. Four EVA's are planned to make the necessary repairs and replacements on the telescope. The STS-103 crew members are Commander Curtis L. Brown Jr., Pilot Scott J. Kelly, Steven L. Smith, C. Michael Foale (Ph.D.), John M. Grunsfeld (Ph.D.), and Claude Nicollier of Switzerland and Jean-François Clervoy of France, both with the European Space Agency. 11/13/1999

nspecciona el cable de seguridad rango entre el tanque externo y cohetes de combustible sólido (SRB) en la misión STS-103 / transbordador espacial Discovery.

Rodney Wilson, with United Space Alliance, inspects the range safety cable between the external tank and solid rocket boosters (SRB) on STS-103/Space Shuttle Discovery. The cable, which relays a redundant emergency destruction signal between the SRBs in the unlikely event of a contingency, was damaged during close-out operations and is being replaced. Discovery's processing schedule leads to a target launch date of Dec. 6. 11/09/1999
