Any one know of any good interplanetary ssto vtol's?

I've been looking for some interplanetary vtol's after discovering this one https://www.simplerockets.com/c/HVeP2H/GNIJ-11-Self-Refueling-Nuclear-VTOL-Ion-SSTO
And I think its really cool and I've been looking for More and I've had no luck so I'm hoping there are some other people who know of any, I'm looking for ones that are big, assisted or auto landing (optional), SSTO, and are semi easy to fly
