Will future US space efforts involve a manned lunar program? If so, I hope that it will have its first flight when most Apollo astronauts are still alive. This would make it possible to do something of high symbolic value to pass the torch between generations of space explorers: having Apollo astronauts serve as “honorary CAPCOMs.”
Apollo astronauts might sit at the CAPCOM console and notify the first lunar return crew GO/NO GO decisions for certain mission maneuvers or events. It would be great to have Mike Collins, for example, give the first lunar crew a GO for translunar injection. Or let Charlie Duke give a GO for powered descent.
Back to the future. Just my 0.02 dreams.
