Idea Shuttle payloads that never flew

[Graham2001]

I've located the report dealing on the Research & Applications Module (RAM) which was the more ambitious predecessor to Spacelab.

Research & Applications Module



Aside from Spacelab like functions,...



...it could be attached to a space station (See The 12 Man Space Station)...



...or be used as a free floating platform.

25-100kW Orbital Power Module


A version of the Power Module was modelled as part of [ame=http://www.orbithangar.com/searchid.php?ID=3555]Skylab 80[/ame], but since that addon came out information on a later design appeared on the NTRS.

The revised design was intended to be expandable from 25kw to 100kw in power.



25kW Power Module, Outboard & Inboard Profile



50kW Power Module, Outboard & Inboard Profile



100kW Power Module, Outboard & Inboard Profile



In addition to the possible use with a salvaged Skylab, use as the core of a small space station was also considered.



The station would be constructed from modified Spacelab components, such as the materials processing pallet shown below.

Large Space Telescope

The ancestor of Hubble. A 3m diameter telescope placed into a 611km high orbit inclined at 28.5 degrees to the equator by a shuttle fitted with an 'OMS Kit' (As far as I can tell a fuel bladder in the payload bay, research is continuing.)

Unlike Hubble this telescope was designed with a docking compartment designed to be pressurised using the shuttles life support system so that maintenance could be carried out in a shirt-sleeve environment.

The following is probably the biggest thing I am going to post in this thread. It also ties in with the Research & Applications Module material I posted earlier.

The 12 Person Space Station



This is the space station that NASA was designing in parallel with the Space Shuttle until 'Tricky Dick' pulled the funding in early '72.

The first phase or Initial Space Station (InSS) to be assembled through successive shuttle launches.

Construction would begin by placing the three sections of the InSS into a 500km high/55 degree inclination orbit in the configuration below

InSS



The InSS would hold a rotating six person crew and would eventually be expanded to a 12 person station. Crew would be transported aboard the Shuttles transporting either Research/Applications Modules or Logsitics Modules

Logistics Module



In the event of an emergency the Logistics Module could be configured to carry six people.



One possible problem is that when this design was finalised (December 1971), NASA had not finalised the shuttle design. McDonnell-Douglas who designed this station used the shuttle configuration below in their planning. Adaptions may need to be made.

One proposed payload for the Shuttle was the Sortie Module (Later SpaceLab). Here are configurations for proposed missions to carry out Earth Resources studies. (Later permanently given over to the unmanned Landsat series.)

I've located another pallet mounted payload. It's a proposed test-bed called the Shuttle Modular Scanning Spectro-radiometer.

The purpose of the self-contained experiment, which would have been mounted in a standard Spacelab pallet, was to test proposed Earth Resources sensing equipment before comitting to a full scale program.

As designed it could also be used as one of the pallets fitted to the 25-100kW Orbital Power Module (See above)





Preliminary Design Study, Shuttle Modular Scanning Spectroradiometer, Final Report

 

[Graham2001]

The first of a series of related proposals by Convair.

In the late 70's one project NASA hitched it's future to was the construction of Orbiting Solar Power Stations. One key component was machinery to build the stations in orbit.

Large Space Structures Fabrication Experiment



This is the earliest proposed test mission for a beam building machine I've found so far. Intended to be launched in March 1982, it would see a shuttle carry a prototype beam builder into orbit mounted on two modified Spacelab pallets, either on it's own or as part of a joint mission.



Over a period of three days a structural beam of 100m length would be built, it's structural integrity tested and then cut into segments for return to Earth See below for a mission timeline for the three day testing period.

Day One



Day Two



Day Three

Large Space Structures Fabrication Experiment, Final Report

For more details on Orbital Solar Power Proposals see the thread "Discussion of an idea, a new World of the Pasts Future."

 

[Graham2001]

The second of the Convair beam builder test missions

Space Construction Automated Fabrication Experiment (SCAFE)

This follow on to the LSSFE would take the form of a dedicated shuttle mission which would use the beam builder tested on the earlier mission to construct a platform that would be left in orbit to study the long term effects of space on the platform.

Thanks for the research, and inspiration.

PS, you can edit, and post the second post after this.

 

[Graham2001]

Thanks Donamy, now onto the next and last of the Convair proposals.

Space Construction Experiment (SCE)

With the abandonment of NASAs plans for orbital solar power stations in the early 1980's Convair was forced to scale down its plans to test out a beam builder in orbit to a simple test of a prebuilt length of structural beam of the type that a beam builder could produce.

NOTE: This project seems to have been evolving fairly rapidly as the planning went on. What started out a something involving EVAs and use of the shuttle RCS system to set the structure vibrating changed into a more 'self contained' project where the aparatus contained all the equipment to carry out the test functions.

I'm currently reviewing some North American/Rockwell space construction studies, but they are very poorly scanned.

[slightly off-topic] Anybody here working on the Shuttle payloads of the 1990s (or roughly most payloads between 1998 and 2003)? [/slightly off-topic]

Yes, but that one lacks the large platform for smaller experiments, but adds a more modular multi-purpose architecture.

True, though both were based around the use of payloads fitted to standard Spacelab pallets, I've posted examples earler (See: Post 22 & Post 26)

One other unflown pallet payload I've recently uncovered is an experimental 30m diameter radio antenna which would have been deployed in a manner not too different to an umbrella.

I seem to be getting a strange urge, to build something.:lol:

Your urge is at least only coming with minor implications for your environment.

I have the urge to get this valar-damned new development PC ASAP.

Here is another pallet based payload, this was an Earth observations system, using microwave radiometry. The other item shown in the payload bay view is apparently an OMS kit, an item I'm still researching.
