Summary:
The Shuttle Discovery and its seven crewmembers are now in orbit after cruising through key flight milestones. On mission STS-114, the crew will perform inspections on orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay.

Solid Rocket Booster separation was triggered 2-minutes and 5-seconds into the flight after burnout of the putty-like fuel packed inside each rocket. The firing of explosive bolts freed the twin boosters from the side of the External Tank, allowing them to peel away from the Space Shuttle. Parachutes were then automatically deployed from the boosters, allowing them to slowly descend into the Atlantic Ocean where they will be towed back to shore.

Discovery initiated the command for Main Engine Cutoff, or MECO, at the 8-minute, 23-second mark. MECO shuts down the orbiter's three powerful engines in the rear of Discovery after completing the "uphill" climb into space.

With the ascent into space complete and fuel onboard the External Tank exhausted, Discovery jettisoned the orange canister. Following jettison, Discovery used it's new belly-mounted digital camera to take pictures of the tank as it fell back into Earth's atmosphere.

This historic mission is the 114th Space Shuttle flight and the 17th U.S. flight to the International Space Station. STS-114 is scheduled to last about 12 days, with a planned KSC landing at about 5:46 a.m. EDT Aug. 7.

Discovery's first launch attempt was July 13 and was postponed at 1:30 p.m. EDT. During countdown activities, a low-level fuel cut-off sensor located inside the External Tank failed a routine prelaunch check. The sensor protects a Shuttle's main engines by triggering their shut- down in the event that fuel runs unexpectedly low. The sensor is one of four inside the liquid hydrogen section of the External Tank.

Discovery rolled into KSC's Orbiter Processing Facility (OPF) on Aug. 22, 2001, after returning from its last mission STS-105 in August 2001 and undergoing an Orbiter Major Modification period. The Shuttle rolled out of OPF bay 3 and into the Vehicle Assembly Building (VAB) on March 29 this year. While in VAB high bay 1, Discovery was mated to its redesigned External Tank and Solid Rocket Boosters. The entire Space Shuttle stack was transferred to Launch Pad 39B on April 7.

In order to allow for the addition of a new heater to the External Tank, Space Shuttle Discovery was rolled back to the VAB on May 26 for that modification to be performed. Discovery was removed from its External Tank and attached to a new tank originally scheduled to fly with orbiter Atlantis on mission STS-121, the second Return to Flight mission.

Discovery was rolled back out to Launch Pad 39B on June 15 in preparation for the July launch window.

On mission STS-114, the crew will perform inspections on orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay.

In the payload bay, the Multi-Purpose Logistics Module Raffaello, built by the Italian Space Agency, will carry 11 racks with supplies, hardware, equipment and the Human Research Facility-2.

During two additional spacewalks, the crew will install the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure. The STS-114 crew includes Commander Eileen Collins, Pilot James Kelly, and Mission Specialists Soichi Noguchi, Stephen Robinson, Andrew Thomas, Wendy Lawrence and Charles Camarda.
