One thing is sure
No discovery type return capsule for UPWARD
Since the GAMBIT-3 Hull is docks on CSM,
the Astronauts could simply open the LM docking tunnel and remove the Flim-canister from GAMBIT-1.
or was this planed as EVA just like the SIM-bay on Apollo 15-16-17?
Interesting on UPWARD is that NRO was looking into use of Apollo in MOL (at least some of released PDF suggest it)
i guess they abandon the idea because lack of right launch rocket to bring Apollo CSM + GAMBIT in Polar orbit, interference with the Apollo Program,
so Gemini on Titan IIIM was the better choice, since that program was terminated at NASA
>>Spekulation mode on
but what if NRO takes Apollo UPWARD instead MOL ?
Camouflage as USAF/NASA join effort exploring Earth under Apollo Application Program
With modified Saturn IB using Titan solids as first stage
>>Spekulation mode off
