Details, quoting from Smithsonian National Air and Space Museum | Space Shuttle Enterprise:
Manufacturer:
Rockwell International Corporation
Country of Origin:
United States of America
Dimensions:
Overall: 57 ft. tall x 122 ft. long x 78 ft. wing span, 150,000 lb.
(1737.36 x 3718.57 x 2377.44cm, 68039.6kg)
Materials:
Aluminum airframe and body with some fiberglass features; payload bay doors are graphite epoxy composite; thermal tiles are simulated (polyurethane foam) except for test samples of actual tiles and thermal blankets.
The first Space Shuttle orbiter, "Enterprise," is a full-scale test vehicle used for flights in the atmosphere and tests on the ground; it is not equipped for spaceflight. Although the airframe and flight control elements are like those of the Shuttles flown in space, this vehicle has no propulsion system and only simulated thermal tiles because these features were not needed for atmospheric and ground tests. "Enterprise" was rolled out at Rockwell International’s assembly facility in Palmdale, California, in 1976. In 1977, it entered service for a nine-month-long approach-and-landing test flight program. Thereafter it was used for vibration tests and fit checks at NASA centers, and it also appeared in the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans. In 1985, NASA transferred "Enterprise" to the Smithsonian Institution’s National Air and Space Museum.

Quoting from Wikipedia | Space Shuttle Enterprise:
The Space Shuttle Enterprise (NASA Orbiter Vehicle Designation: OV-101) was the first Space Shuttle orbiter. It was built for NASA as part of the Space Shuttle program to perform test flights in the atmosphere. It was constructed without engines or a functional heat shield, and was therefore not capable of spaceflight.
Originally, Enterprise had been intended to be refitted for orbital flight, which would have made it the second space shuttle to fly after Columbia. However, during the construction of Columbia, details of the final design changed, particularly with regard to the weight of the fuselage and wings. Refitting Enterprise for spaceflight would have involved dismantling the orbiter and returning the sections to subcontractors across the country. As this was an expensive proposition, it was determined to be less costly to build Challenger around a body frame (STA-099) that had been created as a test article. Similarly, Enterprise was considered for refit to replace Challenger after the latter was destroyed, but Endeavour was built from structural spares instead.
Service
Construction began on the first orbiter on June 4, 1974. Designated OV-101, it was originally planned to be named Constitution and unveiled on Constitution Day, September 17, 1976. A write-in campaign by Trekkies to President Gerald Ford asked that the orbiter be named after the Starship Enterprise, featured on the television show Star Trek. Although Ford did not mention the campaign, the president—who during World War II had served on the aircraft carrier USS Monterey (CVL-26) that served with USS Enterprise (CV-6)—said that he was "partial to the name" and overrode NASA officials.
The design of OV-101 was not the same as that planned for OV-102, the first flight model; the tail was constructed differently, and it did not have the interfaces to mount OMS pods. A large number of subsystems—ranging from main engines to radar equipment—were not installed on this vehicle, but the capacity to add them in the future was retained. Instead of a thermal protection system, its surface was primarily fiberglass.
In mid-1976, the orbiter was used for ground vibration tests, allowing engineers to compare data from an actual flight vehicle with theoretical models.
On September 17, 1976, Enterprise was rolled out of Rockwell’s plant at Palmdale, California. In recognition of its fictional namesake, Star Trek creator Gene Roddenberry and most of the principal cast of the original series of Star Trek were on hand at the dedication ceremony.
Approach and landing tests (ALT)
Main article: Approach and Landing Tests
On January 31, 1977, it was taken by road to Dryden Flight Research Center at Edwards Air Force Base, to begin operational testing.
While at NASA Dryden, Enterprise was used by NASA for a variety of ground and flight tests intended to validate aspects of the shuttle program. The initial nine-month testing period was referred to by the acronym ALT, for "Approach and Landing Test". These tests included a maiden "flight" on February 18, 1977 atop a Boeing 747 Shuttle Carrier Aircraft (SCA) to measure structural loads and ground handling and braking characteristics of the mated system. Ground tests of all orbiter subsystems were carried out to verify functionality prior to atmospheric flight.
The mated Enterprise/SCA combination was then subjected to five test flights with Enterprise unmanned and unactivated. The purpose of these test flights was to measure the flight characteristics of the mated combination. These tests were followed with three test flights with Enterprise manned to test the shuttle flight control systems.
Enterprise underwent five free flights where the craft separated from the SCA and was landed under astronaut control. These tests verified the flight characteristics of the orbiter design and were carried out under several aerodynamic and weight configurations. On the fifth and final glider flight, pilot-induced oscillation problems were revealed, which had to be addressed before the first orbital launch occurred.
On August 12, 1977, the space shuttle Enterprise flew on its own for the first time.
Preparation for STS-1
Following the ALT program, Enterprise was ferried among several NASA facilities to configure the craft for vibration testing. In June 1979, it was mated with an external tank and solid rocket boosters (known as a boilerplate configuration) and tested in a launch configuration at Kennedy Space Center Launch Pad 39A.
Retirement
With the completion of critical testing, Enterprise was partially disassembled to allow certain components to be reused in other shuttles, then underwent an international tour visiting France, Germany, Italy, the United Kingdom, Canada, and the U.S. states of California, Alabama, and Louisiana (during the 1984 Louisiana World Exposition). It was also used to fit-check the never-used shuttle launch pad at Vandenberg AFB, California. Finally, on November 18, 1985, Enterprise was ferried to Washington, D.C., where it became property of the Smithsonian Institution.
Post-Challenger
After the Challenger disaster, NASA considered using Enterprise as a replacement. However refitting the shuttle with all of the necessary equipment needed for it to be used in space was considered, but instead it was decided to use spares constructed at the same time as Discovery and Atlantis to build Endeavour.
Post-Columbia
In 2003, after the breakup of Columbia during re-entry, the Columbia Accident Investigation Board conducted tests at Southwest Research Institute, which used an air gun to shoot foam blocks of similar size, mass and speed to that which struck Columbia at a test structure which mechanically replicated the orbiter wing leading edge. They removed a fiberglass panel from Enterprise’s wing to perform analysis of the material and attached it to the test structure, then shot a foam block at it. While the panel was not broken as a result of the test, the impact was enough to permanently deform a seal. As the reinforced carbon-carbon (RCC) panel on Columbia was 2.5 times weaker, this suggested that the RCC leading edge would have been shattered. Additional tests on the fiberglass were canceled in order not to risk damaging the test apparatus, and a panel from Discovery was tested to determine the effects of the foam on a similarly-aged RCC leading edge. On July 7, 2003, a foam impact test created a hole 41 cm by 42.5 cm (16.1 inches by 16.7 inches) in the protective RCC panel. The tests clearly demonstrated that a foam impact of the type Columbia sustained could seriously breach the protective RCC panels on the wing leading edge.
The board determined that the probable cause of the accident was that the foam impact caused a breach of a reinforced carbon-carbon panel along the leading edge of Columbia’s left wing, allowing hot gases generated during re-entry to enter the wing and cause structural collapse. This caused Columbia to spin out of control, breaking up with the loss of the entire crew.
Museum exhibit
Enterprise was stored at the Smithsonian’s hangar at Washington Dulles International Airport before it was restored and moved to the newly built Smithsonian’s National Air and Space Museum‘s Steven F. Udvar-Hazy Center at Dulles International Airport, where it has been the centerpiece of the space collection. On April 12, 2011, NASA announced that Space Shuttle Discovery, the most traveled orbiter in the fleet, will be added to the collection once the Shuttle fleet is retired. When that happens, Enterprise will be moved to the Intrepid Sea-Air-Space Museum in New York City, to a newly constructed hangar adjacent to the museum. In preparation for the anticipated relocation, engineers evaluated the vehicle in early 2010 and determined that it was safe to fly on the Shuttle Carrier Aircraft once again.
My confession

Slowly and gravely the Witch repeated, “There is no sun.” And they all said nothing. She repeated, in a softer and deeper voice, “There is no sun.” After a pause, and after a struggle in their minds, all four of them said together, “You are right. There is no sun.” It was such a relief to give in and say it.
“There never was a sun,” said the Witch.
“No. There never was a sun,” said the Prince, and the Marsh-wiggle, and the children.
For the last few minutes Jill had been feeling that there was something important she must remember at all costs. And now she did. But it was dreadfully hard to say it. She felt as if huge weights were laid on her lips. At last, with an effort that seemed to take all the good out of her, she said: “There’s Aslan.”
“Aslan?” said the Witch, quickening ever so slightly the pace of her thrumming. “What a pretty name! What does it mean?”
“He is the great Lion who called us out of our own world,” said Scrubb, “and sent us into this to find Prince Rilian.”
“What is a lion?” asked the Witch.
“Oh, Hang it all!” said Scrubb. “Don’t you know? How can we describe it to her? Have you seen a cat?”
“Surely,” said the Queen. “I love cats.”
“Well, a lion is a little bit-only a little bit, mind you-like a huge cat-with a mane. At least, it’s not like a horse’s mane, you know, it’s more like a judge’s wig. And it’s yellow. And terrifically strong.”
The Witch shook her head. “I see,” she said, “that we should do no better with your lion, as you call it, than we did with your sun. You have seen lamps, and so you imagined a bigger and better lamp and called it the sun. You’ve seen cats, and now you want a bigger and better cat, and it’s to be called a lion. Well, ’tis a pretty make-believe, though, to say truth, it would suit you all better if you were younger. And look how you can put nothing into you make-believe without copying it from the real world, this world of mine, which is the only world. But even you children are too old for such play. As for you, my lord Prince, that art a man full grown, fie upon you! Are you not ashamed of such toys? Come, all of you. Put away these childish tricks. I have work for you all in the real world. There is no Narnia, no Overworld, no sky, no sun, no Aslan. And now, to bed all. And let us begin a wiser life tomorrow. But, first, to bed; to sleep; deep sleep, soft pillows, sleep without foolish dreams."
The Prince and the two children were standing with their heads hung down, their cheeks flushed, their eyes half closed; the strength all gone from them; the enchantment almost complete. But Puddleglum, desperately gathering all his strength, walked over to the fire. Then he did a very brave thing. He knew it wouldn’t hurt him quite as much as it would hurt a human; for his feet (which were bare) were webbed and hard and coldblooded like a duck’s. But he knew it would hurt him badly enough; and so it did. With his bare foot he stamped on the fire, grinding a large part of it into ashes on the flat hearth. And three things happened at once.
First, the sweet heavy smell grew very much less. For though the whole fire had not been put out, a good bit of it had, and what remained smelled very largely of burnt Marsh-wiggle, which is not at all an enchanting smell. This instantly made everyone’s brain far clearer. The Prince and the children held up their heads again and opened their eyes.
Secondly, the Witch, in a loud, terrible voice, utterly different from all the sweet tones she had been using up till now, called out, "What are you doing? Dare to touch my fire again, mud-filth, and I’ll turn the blood to fire inside your veins."
Thirdly, the pain itself made Puddleglum’s head for a moment perfectly clear and he knew exactly what he really thought. There is nothing like a good shock of pain for dissolving certain kinds of magic.
“One word, Ma’am,” he said, coming back from the fire; limping, because of the pain. “One word. All you’ve been saying is quite right, I shouldn’t wonder. I’m a chap who always liked to know the worst and then put the best face I can on it. So I won’t deny any of what you said. But there’s one thing more to be said, even so. Suppose we have only dreamed, or made up, all those things-trees and grass and sun and moon and stars and Aslan himself. Suppose we have. Then all I can say is that, in that case, the made-up things seem a good deal more important than the real ones. Suppose this black pit of a kingdom of yours is the only world. Well, it strikes me as a pretty poor one. And that’s a funny thing, when you come to think of it. We’re just babies making up a game, if you’re right. But four babies playing a game can make a play-world which licks you’re real world hollow. That’s why I’m going to stand by the play-world. I’m on Aslan’s side even if there isn’t any Aslan to lead it. I’m going to live as like a Narnian as I can even if there isn’t any Narnia. So, thanking you kindly for our supper, if these two gentlemen and the young lady are ready, we’re leaving your court at once and setting out in the dark to spend our lives looking for the Overland. Not that our lives will be very long, I should think; but that’s a small loss if the world’s as dull a place as you say.”
