The comments for this thread are now closed.

Sorry, I don’t think so. Not a fan.
As for SeaDragon- I do not think we need to discuss that here.

Lunatic fringe describes this bunch accurately.
I play along with them for fun.
Here’s an example of the work by this person:

I’ve been beating my head against the wall on this topic.

But I digress….

I can imagine the fun you have with the “There is no cheap” line.

Come to think of it, cars are the same way.
There is no cheap. Only what you’re willing to afford…

Either way, it still runs out of propellant, so a depot is still desirable.

Just because you have a fuel efficent vehicle doesn’t mean you never have to refuel it.

You could use a fission fragment rocket, if you want to avoid depot usage. It then transforms more to a “shipyard” usage.

I consider LCROSS on a cost-to-benefit scale to be among the most successful missions that NASA ever mounted. This is because of its profoundly important results accomplished at such low cost.
I’m looking forward to seeing the RESOLVE mission reaching the Moon and accomplishing its ISRU test goals.

They’re one of a dozen or more companies folks would lump into “NewSpace”, though of course the most visible. And many of those are reinventing the wheel to a certain extent. Still, they’re doing well for way less than it’s been done before, and some of them are doing some very novel stuff.

If you want heavy lift, we’ll need to talk about SeaDragon.
