AU Space Shuttle Enterprise
Circa 1985 to 1987
From my Alternative History Post (link) this is how the Space Shuttle Enterprise evolved from the 4th operational orbiter in 1985 to the prototype unmanned shuttle.
More History on the Shuttle:
• April 1983: Enterprise is returned to Palmdale for her disassembled and rebuild.
• As a weight saving measure her mid-fuselage is returned to Convair for a complete rebuild to bring it inline with OV-103 and OV-104.
• to further lighten her frame, her aft-fuselage is rebuilt with similar materials as her sisters.
• Engineers at Rockwell suggests rebuilding or replacing her wings as well but NASA doesn't have room in the budget.
• May 1985: at long last, Enterprise is rolled out and joins the fleet. She weighs slightly less than Columbia. Her main issue is her wings are heavier and weaker than the other Orbiters.
• September 1985: STS-21 is Enterprise's first mission
• 1987: During the Shuttle hiatus following the Challenger Disaster, she went through a mini refit that saw her exterior markings change. (NASA in this timeline returned to the Meatball logo sooner than in the OTL)
Circa 1988 to 1993
• April 1988: STS-30 is Enterprise's first launch following the hiatus.
• December 1993: following STS-61, Enterprise is retired due to being the oldest in the fleet. Endeavour takes her place in the fleet.
• June 1994: Enterprise is flown to Dulles Airport, Washington DC, and is given to the Smithsonian for eventual display when the Steven F. Udvar-Hazy Center is built. NASA retains the option recalled her if needed.
• 1998: NASA studies modifying the Shuttle-C software to work on the Space Shuttle and potentially using Enterprise as a reusable Shuttle-C. The reasoning behind this option this configuration would be a cheaper alternative to the X-33 program. However, while the shuttle could be retrofitted with the software, the shuttle would have less cargo capacity than the X-33 and still required use of expensive legacy launch facilities (ie VAB and LC-39). The study ends with only the software in a beta state.
• December 2003: Steven F. Udvar-Hazy Center is opened with Enterprise being one of its major exhibits.
• November 2003: the Shuttle-C software is used to return STS-118 Columbia to Earth and with critical damage to her structure (mainly her port wing and some internal damage from a collapsed landing gear).
• May 2004: NASA recalls Enterprise to replace Columbia.
• August 2004: initial plans are to return her flight, unmodified. However, NASA develops the Shuttle-C software further and changes it's name to A.S.Tr.O.S (Autonomous Space Transport Operating System).
• New wings! Enterprise is fitted with new wings which are of a modified design and lighter and stronger than the wings of her sisters. With other upgrades and modifications, she is slightly lighter than her younger sisters.
• Some within NASA joking refer to her as Enterprise-A, as a reference to Star Trek.
• September 2006: to commemorate the 30th anniversary of her unveiling to the media, Lockheed-Rockwell rolls her out of their Palmdale facility to rechristen the Shuttle. In attendance, Leonard Nimoy, George Takei, Nichelle Nicholas, Walter Koenig, Christopher Doohan and Rod Roddenberry.
- when asked by the media, Leonard remarked she is still a sight to behold and is glad she will continue her mission of exploration.
Enterprise A (unmanned)
• July 2006: to test the A.S.Tr.O.S. during a return to earth and landing, a new series of Approach and Landing Tests (ALT) were conducted with NASA's 747 SCA (N905NA) at the Dryden Flight Research Center, Edwards Air Force Base. 15 flights are flown to put the software in the real world, with two astronauts on board to step in when needed. Barring some higher than normal landing speeds, the software passes all of its objectives.
• It should be noted, while the rebuilt Enterprise is mainly used as an unmanned orbiter, this is a misnomer. It is more accurate to call her a hybrid shuttle. NASA has the option to convert her back into a manned shuttle if desired or needed.
- This nearly was used in 2015 during STS-154. Space Shuttle Atlantis was after conducting maintenance/upgrades on the Hubble Space Telescope (HST), the crew was unable to disconnect the shuttle from the telescope. CTS-48 Enterprise was already on LC-39B for a cargo mission to the International Space Station. All that was needed was to remove supplies from the payload bay and reinstall the seats in her crew space. Fortunately, this rescue wasn't needed as the Astronauts conducted an unscheduled EVA and manually disconnected the Shuttle from the HST.
• November 2008: first flight of Enterprise-A (CTS-11)
• When Columbia was given a cosmic restoration for her display, the first set of wings from Enterprise was used to replace her damaged one.
• 2019: Enterprise is retired for the final time following CTS-74.
• 2020: Enterprise is on display at Space Center Houston with the restored Star Trek Galileo Shuttlecraft prop.

some more spitballing about that AU but in a new post since that one was getting kind of long:
From Coran, Allura figures out that it may be possible to get someone's memory of the previous reality to return by having them come in contact with a specific trigger. For Coran, it was his control panel on the Castle of Lions.
Which means... she just has to figure out what each paladin's trigger is. Clearly it is not their lions. Keith is proof enough of that. But maybe she can even use it to disrupt Honerva's brainwashing.
Speaking of Keith, it is... deeply weird to see him as an Altean. But also fortunate, because it seems he has a spark of alchemical talent! Which means they can move the Castle of Lions, as soon as they get it in order.
Keith and Romelle are just confused. Why do these two- what did they call themselves again? Humans? Know so much about this ancient Altean ship?
Allura only sort of lies. She tells them she has memories from a past life, as does Coran. Technically very true! She has lived nineteen years as a human. It does make her life as an Altean princess feel a bit like a 'past life'.
Keith's a little wary, but Kosmo seems to trust them, so he decides to trust them both.
local half-Galra turned local Altean born with a lingering sense of something being off, but unable to determine what. He grows up wary and naturally suspicious. except for Romelle. he trusts Romelle implicitly.
(ironically, it was this same wariness that prompted him to never be around whenever Honerva visited. he was under her nose the entire time, and she never knew)
Keith and Romelle out on their own in the universe. What will they do? (acquire a cosmic wolf, an ancient Altean superweapon, and stumble upon an ancient Altean castle. they're keeping themselves busy.)
Pidge is Olkari and Hunk is Balmeran. These are obvious. If we had confirmation that the merpeople could get legs, I would make Lance one of them, but we don't so I feel like he's Puigian? I think Shiro's just Galra again. He gets to be fuzzy this time.
Coran gets to speedrun the sense of strangeness that Allura has lived with all her life, of being one thing and then suddenly another. It's fun!
(Allura overhears Keith and Romelle whispering to each other about their 'weird ears'. oh. now she knows how Lance felt.)
Allura is going to have to somehow teach Keith at least the fundamentals of Altean alchemy without being able to do it herself. That... shouldn't be hard, right?
(it very much is)
Their luck runs out eventually, and Honerva becomes aware that the Castle of Lions is active again. And onboard is a human girl who resembles Princess Allura far too closely for her comfort...

Ezra stumbled into class a couple minutes late, but he was sure his professor would understand. It wasn't his fault that spectre_pheonix had been streaming late last night, right? As long as he quietly slipped into the back of the classroom, no one would notice anyways.
"Mr. Bridger," Professor Syndulla called to him as he tried in vain to hide his late entry, "so glad you've decided to join us this morning."
Ezra turned around and tried to hide his guilty expression.
"Of course, ma'am," Ezra said, with a dramatic salute, "I'd never miss out on one of my favorite teacher's classes."
"Flattery gets you nowhere in my class," the professor said, "take a seat, and we'll continue."
"Yes ma'am," Ezra said. He took a seat as close to the back of the room as he could and pulled out his laptop to take notes.
Ezra tried his best to pay attention, but the lack of sleep was getting the better of him as Professor Syndulla's lesson dragged on.

After almost a standard hour's ride, the speeder bike stopped at the base of a nearby mountain.
"Here we are," the younger voice behind her said, "home sweet home, for the time being anyways."
Sabine stared at the mountain face in front of them as her "kidnappers" both helped her off the speeder bike, each of them holding onto one of her arms, probably so she wouldn't run off— which was excellent foresight, because that's exactly what she wanted to do.
👨👦sobering reflections
Ughtred was too young to be told all the details of that stormy night, but ever wise beyond his years, he'd pieced most of it together on his own. His father had tried to hurt Aunt Betty. Lord Mount Dunstan had saved her. Ughtred had been sent to his room before his father returned a week later, but he'd always been a light sleeper, heard enough to know that his father was ill, somehow beaten and injured to the point that he could scarcely move, and would be confined to a bed in the farthest wing of the estate for the rest of his miserable days.
No one ever spoke of what had happened to Sir Nigel, but in some unspoken way the whole household knew anyways, and Ughtred held his soon-to-be uncle in higher respect ever since.
Thanks for the asks!

The complete Shuttle Fleet AU
This is just my thoughts about how things might align for Enterprise to be refitted into an operational shuttle. This comes after reading a lot of the behind the scenes decisions and abandoned plans NASA had over the last 40 years. I only listed major events.
It wasn't meant to be this long but I hyperfocused too much on it one morning. Anyways, I hope you enjoy it.
• 1972: NASA started the Space Shuttle Program.
• OV-101 Enterprise: same rollout and testing as our timeline in 1976-77
•STA-099: delivered to Lockheed for structural load tests to simulate the launch and re-entry of an operational orbiter in February 1978.
• Point of divergent: The decision to use STA-099 instead of OV-101 as the second operational orbiter came too late as the frame was already tested to 90% stress load. At this point, it would be too costly to repair and bring it back inline. It was decided to continue testing to destruction (as was originally planned in our timeline), although some parts are removed to be refurbished for OV-103.
• OV-102 Columbia completed and rolled out in March 1980. (NASA doesn't relocate Columbia to KSC in March 1979 in an attempt to speed up her tile installation, which only delayed her completion).
•STS-1 is launched in December 1980 (instead of April 1981)
• NASA gives the go ahead to add Enterprise to the fleet and have her rebuilt after Congress increases their budget, but the work would start once OV-104 is completed.
• 1981: long led items for Enterprise's rebuild are started. This includes a new crew pressure vessel and a new aft-fuselage.
• OV-103, starts earlier and it's production is accelerated with parts salvaged from STA-099 (such as the forward fuselage upper section, elevons and vertical stabilizer). Construction completed in 1982 and christened Challenger.
source
• 1983: STS-7 is Challenger's maiden mission. Onboard is Sally Ride.
• 1983: OV-104 is competed and christened Discovery.
source
• STS-12 is Discovery's first mission.
Note: NASA never uses the STS-41-D format. Where the first digit indicating the federal fiscal year, second digit indicating the launch site (1 was Kennedy Space Center and 2 was Space Launch Complex 6 at Vandenberg Air Force Base), and the letter indicating scheduling sequence. This was due NASA Administrator James M. Beggs's triskaidekaphobia (fear of the number 13). In this timeline, the assistant admins were able to talk him out of it and simply skip STS-13.
• 1983: Enterprise is returned to Palmdale for her disassembled and rebuild. As a weight saving measure her mid-fuselage is returned to Convair for a complete rebuild to bring it inline with OV-103 and OV-104.
source
• 1985: at long last, Enterprise is rolled out and joins the fleet. She weighs about the same as Columbia despite weight saving implemented during her rebuild.
• 1985: Columbia is returned to Palmdale for refurbishment and to remove testing equipment (most notable is the ejection seats). This sees her thermal protection system revised and her 32,000 tiles reduced to 24,300. Most are replaced by Advanced Flexible Reusable Surface Insulation blankets which was used on the other three orbiters.
• September 1985: STS-21 is Enterprise's first mission
• STS-25 (STS-51-L in our timeline) launches at a later date due to NASA management listening to the Engineers about icy conditions on January 26, 1986. NASA quietly orders the complete redesign of the Solid Rocket Boosters.
• May 1986: tragedy strikes OV-103 Challenger during STS-27, when the attempted launch of the Centaur carrying the Ulysses probe explodes killing all those onboard. (A real fear in our timeline.)
source
• The Shuttle fleet is grounded for a year, during the investigation. Ultimately the Investigation board concluds NASA was trying to do too much with too limited a system/funding and is used by the administration to demand a bigger budget. (It has less of an impact on the American psyche since it wasn't televised).
• The USAF cancels all Shuttle missions from Vandeberg Air Force Base. (Same as our timeline)
• With an increased budget, NASA agrees to Rockwell's offer to build two new orbiters for the price of one offer.
• 1986: Columbia is returned to NASA after her refurbishment. However, he is placed into storage with the rest of the fleet.
• 1987: return to flight with STS-28 with Discovery. Also first launch with the redesigned SRBs.
• 1988: NASA launches the Shuttle-C program (or Cargo Transportation System), an expendable unmanned cargo pod, using the existing shuttle hardware. The goal is to increase the number of launches by augmenting the Orbiters and reduce the risks to human lives.
•1988: STS-29 Atlantis suffers a foam strike during launch. Post flight analysis determines the foam came from the bipod connected the ET near the top to the front underside of the orbiter. The orbiter was nearly lost during re-entry if it weren't for the fact the strike happened to a tile that was over less critical areas and the missing tile was over a steel patch for an antenna, which gave extra protection to the spacecraft structure. NASA removes the foam from the bipod connection on all missions going forward.
• OV-105 is built from spares from Challenger and Discovery. Completed in 1990 and christened Atlantis. Her design is the first to include a glass cockpit and other improvements.
• 1991: STS-45 is Atlantis's first mission
• OV-106 is a complete to an slightly improved design, making her lighter and stronger than her sisters. Externally she looks the same. Completed in 1992 and is christened Endeavour.
source
- Structural spares are built to replace the ones used in Atlantis's construction and are designated OV-107.
• 1992: first launch of the Shuttle-C (CTS-1). Mission was a success, carrying a DoD payload.

• 1993: STS-59 is Endeavour's first mission
• Rockwell International merges with Lockheed to become Lockheed-Rockwell.
• December 1993: OV-101 Enterprise is retired due to being the oldest in the fleet. Endeavour takes her place in the fleet. Enterprise is given to the Smithsonian with the option of being recalled by NASA if needed.
• 1994: NASA launches the X-33 program to compliment the shuttle as an unmanned reusable launch vehicle (RLV) and replace the Shuttle-C.
• 1996: CTS-5 carries the first component of the International Space Station.

•1996: the Shuttle-C program is cancelled to divert funds to the X-33 program.
• 1998: Lockheed-Rockwell design is selected over proposals from McDonnell-Douglas and Northrop-Grumman/Boeing
SDASM Archives: 08_00991
• 1998: NASA begins the X-38 CRV (Crew Return Vehicle) program. The CRV is designed to be a lifeboat for the ISS.
• 2001: X-33 RLV program is shelved due to technical challenges and budget cuts.
• 2003: STS-118, Columbia conducts her first (and only) mission to the International Space Station. While docked, it was discovered an ice strike damaged her reinforced carbon–carbon leading wing edge panel. The crew stays in the ISS a week while waiting for rescue from STS-119 Atlantis. NASA jerry-riggs an autopilot system to have Columbia re-enter the atmosphere unmanned after her leading edge was temporarily repaired. It was expected for her to burn up in the atmosphere and what remained to land in the Pacific Ocean near Hawaii. However, against all odds Columbia survives and lands at Edwards Air Force Base. Although her port land gear collapsed during breaking after tough down and caused additional damage to the batter shuttle.
• The crew of STS-118 ride back on STS-119 Atlantis and land in Kennedy Space Center.
• Unfortunately, the damage to Columbia is too extensive and she is retired. She is placed in storage at Palmdale, California.
• In the wake, NASA begins Project Constellation, with the goal being to complete the original space transportation system (STS) mission. Which was a reusable system to carry astronauts to the moon and beyond. NASA and the US calls on the international community to fund and build the components.
NASA ID: MSFC-70-PD-4085 B
• The ET is modified with a half shell to remove the risks of form/ice strikes and the Shuttle TPS is upgraded with the materials from the shelved X-33 program.
• OV-101 Enterprise is recalled by NASA to be the prototype of an unmanned shuttle and is given a thorough rebuild with newer and lighter wings and other components but entirely unmanned. Some joking refer to her as Enterprise-A, as a reference to Star Trek.
• NASA funds Lockheed-Rockwell to build OV-107, another uncrewed version, to augment Enterprise.
• The ISS construction continues but becomes a research/launching platform for missions to the moon and ultimately beyond
• 2004: the X-38 is launched on a liftover Shuttle-C, modified for lifting body, to the ISS (CTS-10).

• 2009: NASA announces the rocket that will carry the components of the Constellation programs beyond Earth orbit will be called the SLS (Space Launch System). Boeing was selected to build the core stage. The SLS will used SSME at the end of their life's and newly constructed expendable versions. A third launch, pad 39C, will be constructed for the SLS.
• 2009: Lunar Transfer Vehicle (LTV, later renamed Orion) is used to transfer crews from LEO to Lunar orbit. Two components make up the vehicle. The crew section is to be built by NASA/CSA and the fuel/propulsion section built by the ESA. The SLS will be used to launch the fuel/propulsion section of the LTV.
- OV-101 and OV-107 are used to launch the crew section of the LTV. Which will rendezvous with the ISS.
- SLS Block II, an upgraded version, is use to launch the Gateway components. Gateway components will be built in the ESA and Japan.
- A Lunar space station, Gateway, launched and constructed in lunar orbit for Orion to rendezvous and house the Altair lunar lander. Three Orions are kept in orbit, one at each station in case of an emergency and a third in use.
• The first is find locations with abundant raw materials for fuel the future moonbase.
• 2010: NASA announces the X-50 SSTO Program and the Commercial Crew Program, with the goal of replacing the Shuttle (including the Enterprise and Constitution). The X-50 is the successor to the X-33.
