      An oddly "close" movie you could watch if you want to scratch that itch is Space Cowboys (2000), where a team of angry old astronauts are brought out of retirement to rendezvous with and an old failing satellite (that they are familiar with) on a short timeframe before it causes some calamity. But all is not as it seems! Don't expect high cinema, but it's worth a watch!

      How would they be able to do that with a fixed payload size and mass requirement? The only practical way they’d be able to use the shuttle to retrieve a flying satellite is if they designed the satellite themselves to fit in the bay like Scott says in the remainder of this video.

    I think it’s also worth mentioning in order to meet these USAF “requirements” the orbiter grew in size and complexity, the winged reusable booster grew with it. In order to control the spiralling development cost the booster was dropped reducing STS from reusable to “repairable” Along with it went any hope of reducing $/Kg price to orbit. Both accidents can be said to have stemmed from from that USAF requirement and the resulting design cascade.

    • @HalNordmann
      @HalNordmann 3 роки тому +20

      It was not only the USAF. NASA also appreciated the idea of bigger cargo bay and bigger wings - greater crossrange also means bigger margin for error during landing, and you can carry up bigger satelites/stations.
      Fun fact: Some of the "Phase B" shuttles (like the Rockwell NAR-161/B9U or the McDonnell Douglas design) had all the good features of the modern Shuttle - like the big crossrange or capable cargo bay - and still were fully reusable.

      No, they cannot be said to have stemmed from the Air Force decisions. Using that logic, we can say the idea to CREATE an orbiter of ANY kind led to the wrecks. Or the creation of NASA. Or the creation of the USAF. The spiraling of the USAF from the US Army Air Force, which it was a part to in past times. No...the first one was disregarding seasoned engineers advising that a launch could go forward and operate with an extremely high rate of nomility, IF the temperatures were not insignificantly warmer. The second disaster was hard to be avoided but could have been with subtle design changes. As for when the accident had already occurred, EXPERIENCED people who WERE concerned were ignored, including people who offered access to Hubble-like telescopes in different defense agencies in America in order to take a look at the damage on the orbiter. What kind of rescue mission would have/could have ensued will be unfortunately, forever unknown.

    Fun fact.
    Sometime in the mid-80s I worked for a company that was contracted to do the steel construction drawings to retrofit the Vandenberg Assembly Building for the space shuttle. We were given two sets of design drawings, had to sign nda's and we're not allowed to copy the designs in any way. We were only contracted to draw the service platforms that folded back out of the way of the launch vehicle so that the Assembly Building could be rolled back. The platforms were designed to fit the profile of the launch vehicle so they had lots of curves and strange angles in order to fold back into the building.

    Back in the late 90s I worked in a building at Vandenberg that had been part of the west coast Shuttle program. I was setting up a projector in a conference room that had curtains all around the walls, and my coworker said "check this out" and pulled back one of the curtains.
    The whole wall was a giant magnetic scheduling white board with little shuttle figures marked with mission numbers, starting with STS-62-A in 1986. Nothing had been touched in close to two decades - someone had just pulled the curtains over it and forgotten it. The base had sad reminders like that everywhere, if you knew where to look. Short, stubby road signs and weird road embankments for wing clearance along the route the orbiter would have been towed, abandoned facilities, that sort of thing.
    The cancellation of the program was devastating to the local economy and it took years to recover. It makes me happy to see SpaceX making such progress with manned space flight. There's been a lot of disappointment and heartbreak over the years.

    It was sad that the program died. A lot of folks like myself put in a lot of effort. The one thing that came out of it was the deicing system that was installed as Vandenberg was further north and more likely to freeze. After the disaster, that system was moved to the cape. It was pretty clever you had two jet engines from an old martin Marrietta fighter program that did not win a final contract. The engines were in a blockhouse near the tower. the warm was ducted between the SRBs and external tanks. I was on the testing team for that one.

    One reason that NASA gave up on flying the Shuttle from SLC-6 is, ironically, part of what makes the Delta 4 launches so vusually exciting, as shown in this video. You know how that fire prior to the Delta 4 launch is the ignition of excess hydrogen that actually singes the foam insulation on the lower part of the Delta first stage? After the Challenger disaster, it became known that SLC-6 had a problem with excess hydrogen building around that pad. Those pre-ignitors that you saw on Shuttle launches from KSC Pad 39A/B that fire off at T-minus 10 seconds were sufficient to handle the amount of excess hydrogen at those Apollo-era pads, but apparently there was way too much hyrdogen pooling around the base of the SLC-6 pad as designed. It would have required extensive engineering to fix the problem. NASA and DoD at some point decided that there were just too many issues to resolve to safely launch Shuttles from Vandenberg (and the need for three Shuttles flying from KSC meant that Atlantis had to fly from KSC until Endeavour came on line), and the project was abandoned.

    I've always heard of mission 3A - launch to the south, deploy a satellite, land immediately - as the cross-range design driver, but I don't think I'd never heard of 3B. It's hard to imagine that actually working. Do the plans talk about launch windows? Not only would there be the usual orbital plane constraint, I'd think the phase angle would require a very narrow, if not instantaneous, window. How often would it ever have been possible?
    I also assume this all would require the lighter external tank, and the lighter SRB casings that never got built.

    • @eddievhfan1984
      @eddievhfan1984 4 роки тому +2

      You're right that the launch window would be ridiculously tight. However, as far back as Gemini 11, direct-ascent rendezvous was a proven part of the space playbook, which by its very nature requires seconds-long launch windows; lunar aborts would also involve direct-ascent rendezvous as well.
      While the lighter tank and SRBs would have definitely helped with performance, lifting a nearly-empty Orbiter into a 220 km apoapsis while minimizing leftover fuel would be feasible with stock hardware, especially considering that the Shuttle doesn't burn through all of its fuel in a nominal ascent, anyways.

Not to mention annoyed beeping of captured Soviet satellite stowed inside!

    Excellent summary, I remember back in 1970s looking forward to VAFB launches so I don't have to leave my home state California. I also had the idea to buy an Amtrak ticket so the train will go through Vandenberg when the Shuttle is launched. Obviously that would never happen and Shuttle SLC6 was cancelled. I think those big delta wings do give orbiter more margin for emergency landings and those stubby wings like the X15 would need unobtainium materials for heat shield. I remember in 1970s all the talk about how Shuttle can be used to service satellites or bring them back to earth. However, I can now see in hindsight the Soviets were fuming at prospect such a vehicle can be used to steal their satellites.
    Also in 1970s I visioned the orbiter returning will fly through the aurora borealis and astronauts get to see a spectacular lightshow like the special effects like that 70s TV show "Buck Rogers in the 25th Century"

    I worked for six years of my aerospace career in Santa Barbara on Earth sciences satellites and was an enthusiastic bicycle commuter while I worked there in a town that loves bicycles. The time that I joined the Solvang Century (100 mile) bike ride, when it had the rare privilege of crossing through the Vandenburg base instead of around it, I was informed to look for a set of specific cuts into the sloped sides of a two lane road climbing portion to get to the top of the main mesa for the base. The 3 mile long runway for landing the shuttle, (extended a mile beyond most large transport and military runways) was atop that mesa and the widening of the cut that the road up to it had been just enough to clear the wings of the shuttle as it was returned to SLC-6. That launch complex was considered an "unlucky" one by those I knew who worked there, including the man I bought my recumbent bike from. Lockheed lost at least a couple of those Taurus launches before they gave up that program.

    For more than 4 decades the hangars with all the signalling equipment, fire trucks, access trucks, even an operating little hospital with operation rooms and isolation areas are still there on the airport.
    Even to date, that area is treated as a don't ask-don't tell part of the Airport, commonlly known as "Los americanos".
    NASA choose the Las Americas airport due to the lenght of it's runway, about 11,500 ft (almost 4 km), which can fit all really big airplanes flying right now, even the Antonov 224 and Airbus A 380.

    Great video. The Vandenberg polar missions in general really pushed the shuttle towards a large delta wing; even if the plan was to land with an empty payload bay in 3A, an abort would force the orbiter to land with a full bay!

      The bigger wings weren't as much of a military's idea as some may think - NASA was already thinking about them for better gliding. Even with bigger wings, the Shuttle was a flying brick with a 1:1 glide ratio - you can't go much lower and still be controllable. Some of the "Phase B" shuttles (like the Rockwell NAR-161/B9U or the McDonnell Douglas design) had all the good features of the modern Shuttle - like the big crossrange or capable cargo bay - and still were fully reusable.

    The mapper camera or forward assembly as it was called, only flew on some hexagon flights. It was not part of the hexagon vehicle. It was a defense mapping agency payload.

    You have to wonder, if 3B was never needed, would the shuttle have been more or even less reliable?

  • @ReneSchickbauer

    Presumably, the shuttle would also need a basic on board radio control system for the satellite (if available), similar to Gemini/Agena. In the optimum case, you'd probably want the sat to be 3 axis stabilized and correctly oriented until capture, quickly passivate it (most likely while out of range of ground control), then move it into the payload bay. Passivation might involve turning off thrusters, stowing or ejecting solar panels and antennas and such.
    If the sat isn't cooperating, either it's spinning, pointing the wrong way or, worst case, refusing to turn off it's RCS thrusters and/or gyros, you'd have a heck of a time getting it safely into the payload bay.

    If you read up on the various books on the Hubble and it's evaluations prior to repair you'd find that the intel agencies were already flying telescopes of equal power and size (the investigators discovered the solar panel 'twang' problem when the Hubble transited day-night cycles from them). The Shuttle was designed to be that large (and risky) specifically to service a fleet of Hubble size recon platforms. Hence all those 'secret launches' in the early 80s as those payloads were deployed.

      It's been an open secret more or less since the 80s that the Hubble Space Telescope is a modified KH-11 KENNAN imaging satellite.
