With ourncurrent technology none of this will happen.
Physical things on this complicated of a ship will fail, and there may be some things that fail that have redundancy, but you can only pack so much replacement materials and redundancy systems. Ultimately things will fail and not be able to be repaired or replaced, and when its a critical system or enough important systems, you’re done.
You say look at the voyager ships. Nowhere as complicated or as many systems, plus they have both failed during mission time and unexpectedly come back. They have no life support, no water systems, no food systems, not a lot of plastics and tubing, not nearly as many computers that will be running multiple systems, not nearly as much physical volume, or air handling/recycling systems with co2 scrubbers, waste removal and reconstituting systems
plus the fact bodies will probably not last as long as we think in 0/reduced gravity situations long term, given how fast things change negatively for astronauts just a few months on the iss despite the regimented daily physical working uot they do to offset it.
nope. not with our current technology. moon, yep, right now. mars, maybe once engines can get us there in a few months, and that’s going to happen. ut not interstellar missions. we need a time/space warp type engine to do that. when we can fold space and pinch a point 4 light years away to where we are, then unpinch it and then we’re there, that’s what is going to make interstellar missions viable.
Good comments.
A crewed aircraft or space mission is dependent on a fairly significant amount of weight and equipment needed to maintain survivability and recovery of a crew.
I would like to see more robotics deployed. Most bang for the buck.
Humans can rehearse bio needs on the moon. Robotics to mine the abundant H³ found there and techs to keep the robitics in good working condition. Housing will eventually go to the volcanic lava tubes, properly fitted out, as sans atmosphere the radiation can’t really be controlled any other way.
Life kinda sucks out there in the wilds of the heliosphere.
