So KSP 2 is coming out in 2020 very soon. I wanted to add an expansion package based on the 1998 Lost in Space film.
These include:
Jool 2 spacecraft (based on the spacecraft seen in the film, called Jupiter 2)
Jool 1 booster rocket (based on the Jupiter 1 booster rocket also seen in the film, with Super Large fairings with holes to mount rocket engines)
Jettisonable adapter for the bottom of the Jool 1 booster
Launch tower for the Jool 1 booster/Jool 2 spacecraft (with crew access arm and umbilical masts, new launch pad addition)
Extension of "R-12 'Doughnut' External Tank" called "R-20 Large Jettisonable Sliced External Tank"
