S89-42940 (April 1989) --- In this artist's rendition, the Galileo spacecraft is being boosted into its inter-planetary trajectory by the Inertial Upper Stage (IUS) rocket.  The Space Shuttle Atlantis, which is scheduled to take Galileo and the IUS from Earth's surface into space, is depicted against the curve of Earth.  Galileo will be placed on a trajectory to Venus, from which it will return to Earth at higher velocity and then gain still more energy in two gravity-assist passes, until it has enough velocity to reach Jupiter.  Passing Venus, it will take scientific data using instruments designed for observing Jupiter; later, it will make measurements at Earth and the moon, crossing above the moon's north pole in the second pass.  Between the two Earth passes, it will edge into the asteroid belt, beyond Mars' orbit; there, the first close-up observation of an asteroid is planned.  Crossing the belt later, another asteroid flyby is possible.

The free-flying Tracking and Data Relay Satellite-E (TDRS-E), still attached to an Inertial Upper Stage (IUS), was photographed by one of the crewmembers during the STS-43 mission. The TDRS-E was boosted by the IUS into geosynchronous orbit and positioned to remain stationary 22,400 miles above the Pacific Ocean southwest of Hawaii. The TDRS system provides almost uninterrupted communications with Earth-orbiting Shuttles and satellites, and had replaced the intermittent coverage provided by globe-encircling ground tracking stations used during the early space program. The TDRS can transmit and receive data, and track a user spacecraft in a low Earth orbit. The IUS is an unmarned transportation system designed to ferry payloads from low Earth orbit to higher orbits that are unattainable by the Shuttle. The Space Shuttle Orbiter Atlantis for the STS-43 mission was launched on August 2, 1991.

In this photograph, the Chandra X-Ray Observatory (CXO) was installed and mated to the Inertial Upper Stage (IUS) inside the Shuttle Columbia's cargo bay at the Kennedy Space Center. The CXO will help astronomers world-wide better understand the structure and evolution of the universe by studying powerful sources of x-rays such as exploding stars, matter falling into black holes, and other exotic celestial objects. X-ray astronomy can only be done from space because Earth's atmosphere blocks x-rays from reaching the surface. The Observatory provides images that are 50 times more detailed than previous x-ray missions. At more than 45 feet in length and weighing more than 5 tons, the CXO was carried into low-Earth orbit by the Space Shuttle Columbia (STS-93 mission) on July 22, 1999. The Observatory was deployed from the Shuttle's cargo bay at 155 miles above the Earth. Two firings of an attached IUS rocket, and several firings of its own onboard rocket motors, after separating from the IUS, placed the Observatory into its working orbit. The IUS is a solid rocket used to place spacecraft into orbit or boost them away from the Earth on interplanetary missions. Since its first use by NASA in 1983, the IUS has supported a variety of important missions, such as the Tracking and Data Relay Satellite, Galileo spacecraft, Magellan spacecraft, and Ulysses spacecraft. The IUS was built by the Boeing Aerospace Co., at Seattle, Washington and managed by the Marshall Space Flight Center.

This artist's concept drawing depicts the Tracking and Data Relay Satellite-C (TDRS-C), which was the primary payload of the Space Shuttle Discovery on the STS-26 mission, launched on September 29, 1988. The TDRS system provides almost uninterrupted communications with Earth-orbiting Shuttles and satellites, and had replaced the intermittent coverage provided by globe-encircling ground tracking stations used during the early space program. The TDRS can transmit and receive data, and track a user spacecraft in a low Earth orbit. The deployment of TDRS-G on the STS-70 mission being the latest in the series, NASA has successfully launched six TDRSs.
Space Shuttle Projects
STS043-601-033 (2 Aug 1991) --- The Tracking and Data Relay Satellite (TDRS-E), is seen almost as a silhouette in this 70mm image.  The TDRS spacecraft was captured on film as it moved away from the earth-orbiting Atlantis a mere six hours after the shuttle was launched from Pad 39A at Kennedy Space Center, Florida.  TDRS, built by TRW, will be placed in a geosynchronous orbit and after on-orbit testing, which requires several weeks, will be designated TDRS-5.  The communications satellite will replace TDRS-3 at 174 degrees west longitude.  The backbone of NASA's space-to-ground communications, the Tracking and Data Relay Satellites have increased NASA's ability to send and receive data to spacecraft in low-earth orbit to more than  85 percent of the time.  Before TDRS, NASA relied solely on a system of ground stations that permitted communications only 15 percent of the time.  Increased coverage has allowed on-orbit repairs, live television broadcast from space and continuous dialogues between astronaut crews and ground control during critical periods such as space shuttle landings.  The five astronauts of the STS-43   are John E. Blaha, mission commander, Michael a. Baker, pilot, and mission specialists Shannon W. Lucid, G. David Low and James C. Adamson.

S82-41171 (29 Nov. 1982) --- NASA?s tracking and data relay satellite (TDRS) is gently mated to its inertial upper stage (IUS), which will propel the satellite to a higher geosynchronous orbit after it is ejected from the Challenger?s cargo bay during STS-6. Another TDRS will be placed in orbit on a later shuttle mission. The two will provide communications between orbiting shuttle mission craft and the ground, resulting in increased real-time communication and eliminating the need for much of NASA?s extensive world-wide system of ground tracking stations. A more distant plan is to launch other TDRS to be used for commercial telecommunications and for handling peak loads. Photo credit: NASA

The Inertial Upper Stage (IUS) booster is lowered 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. Following that, an end-to-end test (ETE) will be conducted to verify the communications path to Chandra, commanding it as if it were in space. With the world's most powerful X-ray telescope, Chandra will allow scientists from around the world to see previously invisible black holes and high-temperature gas clouds, giving the observatory the potential to rewrite the books on the structure and evolution of our universe.

At Launch Pad 39-B, the Chandra X-ray Observatory sits inside the payload bay of Space Shuttle Columbia, waiting for the doors to close. Chandra is the primary payload on mission STS-93, scheduled to launch aboard Columbia July 20 at 12:36 a.m. EDT. 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. The world's most powerful X-ray telescope, Chandra will allow scientists from around the world to see previously invisible black holes and high-temperature gas clouds, giving the observatory the potential to rewrite the books on the structure and evolution of our universe

STS006-40-685 (4 April 1983) --- This view of a tilted tracking and data relay satellite (TDRS) and part of its inertial upper stage (IUS) was photographed during deployment of the TDRS/IUS tandem some 10 hours following launch of space shuttle Challenger. A 70mm camera was aimed by crew members through the aft windows of the Earth-orbiting Challenger to capture the scene. A tilt-table device was used to lift the TDRS to this position (almost 90 degrees different from its stowed position). Onboard NASA’s second reusable shuttle for this five-day flight were astronauts Paul J. Weitz, Karol J. Bobko, Dr. F. Story Musgrave and Donald H. Peterson. Photo credit: NASA

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. Following that, an end-to-end test (ETE) will be conducted to verify the communications path to Chandra, commanding it as if it were in space. With the world's most powerful X-ray telescope, Chandra will allow scientists from around the world to see previously invisible black holes and high-temperature gas clouds, giving the observatory the potential to rewrite the books on the structure and evolution of our universe.

In the Vertical Processing Facility (VPF), workers watch as the overhead crane starts lifting the shrouded Chandra X-ray Observatory to a vertical position. The telescope will undergo final installation of associated electronic components; it will also be tested, fueled and mated with the Inertial Upper Stage booster. A set of integrated tests will follow. Chandra is scheduled for launch July 9 aboard Space Shuttle Columbia, on mission STS-93 . Formerly called the Advanced X-ray Astrophysics Facility, Chandra comprises three major elements: the spacecraft, the science instrument module (SIM), and the world's most powerful X-ray telescope. Chandra will allow scientists from around the world to see previously invisible black holes and high-temperature gas clouds, giving the observatory the potential to rewrite the books on the structure and evolution of our universe
