Kerbin

Description

A wondrous green and blue world, Kerbin is the only planet known to have given rise to life forms capable of more than instinctive action. Now these life forms, calling themselves Kerbals, seek to depart their nest and set foot in the deep. Half of the grand challenge ahead of them is just getting into orbit. Will they make it?

Trivia

Kerbin possesses "7 seas" permissive to circumnavigation challenges. It also carries 12 hour days and 365 days a year, allowing for hassle-free calendar simulations/operations. Its atmosphere produces more shock heating than stock Kerbin, making heatshields more necessary and making the Deadly Reentry mod less necessary. Its Rational Resources atmosphere template encourages deployment of orbital mining stations near the atmosphere edge. Likewise, several other worlds will provide this encouragement.
