BoeingFan7879
NASA Rockwell Space Shuttle OV-101 "Enterprise"
The Orbiter Enterprise rolled out of its assembly building in Palmdale, CA, in 1976. It was the prototype for all future shuttle orbiters to follow. Its most significant contribution to the shuttle program was the Approach and Landing Test program in 1977, a crucial phase that tested the orbiter's ability to glide and land like an airplane. The Shuttle Carrier Aircraft (SCA), a specially modified Boeing 747, carried the orbiter aloft. The SCA released Enterprise for a gliding approach, proving the concept of a winged spacecraft returning from orbit could successfully make a conventional runway landing.
Enterprise, despite its limitations, flew five of these missions, each lasting only a few minutes. As an atmospheric test vehicle, she did not have the thermal tiles and reinforced carbon-carbon components like the other shuttles. Nor did Enterprise carry larger systems such as engines, radar, and outfitted crew compartments, highlighting the challenges and constraints faced in the early days of space exploration.
After all flight tests were completed, the rest of the orbiter fleet was constructed in succession, and missions to orbit began in 1981. Enterprise was initially considered for upgrading to orbital capability, but this plan was later abandoned, a decision that carried significant weight in the aerospace industry, when it was determined structurally heavier than the other vehicles.
Enterprise was used for ground tests after the disasters of the shuttles Challenger in 1986 and Columbia in 2003. These tests were crucial in understanding the causes of the disasters and improving the safety of future missions. However, most of her career has involved being on static display, from the Paris Air Show in 1983 to the New Orleans World's Fair in 1984 and from 1985 to 2011, when it was part of the National Air and Space Museum's collection at the Udvar-Hazy Center in Virginia. A few years later, she was moved via barge to her new home at the Intrepid.
