At Launch Pad 39-B, the Chandra X-ray Observatory sits inside the payload
bay on mission Space Shuttle Columbia, waiting for the doors to close.
Chandra is the primary payload of STS-93. The combined Chandra/Inertial
Upper Stage, seen here, measures 57 feet long and weighs 50,162 pounds.
Fully deployed with solar arrays extended, the observatory measures 45.3
feet long and 64 feet wide. (Photo: NASA)

Preparation for
Launch
Hours before dawn, the payload canister transporter delivers its cargo
(lower left) to Launch Pad 39B, below the Rotating Service Structure (RSS).

Preparation for
Launch
The payload canister containing Chandra is prepared for its ascent up the
Rotating Service Structure (RSS). The canister arrived at the pad on the
payload canister transporter below it. The canister will be lifted up to
the Payload Changeout Room in the RSS where it will be relieved of its
cargo. After the RSS rotates to a position behind Shuttle Columbia (at
right), the observatory will then be installed vertically in the orbiter
payload bay. (Photo: NASA)

Preparation for
Launch
Space Shuttle Columbia sits on Launch Pad 39B less than two weeks after
liftoff of Discovery on mission STS-96. Columbia was rolled out June 7 in
preparation for the launch of STS-93 with its payload of the Chandra X-ray
Observatory. The Rotating Service Structure, at left, will be moved into
place on Tuesday, June 8. (Photo: NASA)

Preparation for
Launch
The orbiter Columbia is rolled out from the Orbiter Processing Facility
(background) on its transporter. It is being moved to the nearby Vehicle
Assembly Building (VAB) for external tank mating operations. Columbia will
be rolled out to Launch Pad 39B on Monday, June 7, for mission STS-93.

In the Vertical Processing Facility, the Chandra X-ray Observatory is
revealed with its protective cover removed. Chandra is ready for mating
with the Inertial Upper Stage (IUS) beneath it, to be followed by testing
to validate the IUS/Chandra connections and to check the orbiter avionics
interfaces. (Photo: NASA)

Preparation for
Launch
The Inertial Upper Stage (IUS) booster is moved toward a workstand in
Kennedy Space Center's Vertical Processing Facility. The IUS will be mated
with the Chandra X-ray Observatory and then undergo testing to validate the
IUS/Chandra connections and check the orbiter avionics interfaces. (Photo: NASA)

The STS-93 stack of solid rocket boosters and external tank sits at the
Mobile Launcher Platform park site. STS-93 will carry the Chandra X-ray
Observatory into space. (Photo: NASA)
