This is a modification of Real Solar System for KSP 1.8.1, swaping Earth and Mars making the launch site on Mars. Currently there's 8 launch sites: Valles Marineris, Aurorae Chaos, Chryse Planitia, Olympus Mons, Hellas Basin and Utopia Basin, Korolev Crater and Argyre Planitia. Contract system of RP-0 is all changed to deal with this modification. As you start, sounding rocket contracts give you more money to accelerate the progress to go to orbit and X-Plane contracts are all removed because winged crafts don't work on Mars.

Lunar exploration contracts are now separeted in Phobos and Deimos exploration contracts, crewed exploration contracts are now separeted in three categories: Human Exploration of Inner Solar System (this includes exploration of Mercury, Earth, and Venus), Human Exploration of Outer Solar System (this includes exploration of Jupiter and it's moons, exploration of Saturn and Titan) and Human Exploration of Asteroids (this includes exploration of Ceres, Vesta and asteroids).

This is for people that are seeking new things to do in the game, launching from Mars is relatively easy, but landing back on it is a bit trickyer and in a lot of cases requires more then just parachutes.

Note that i'm doing this solo and basicaly just for fun, so maybe there's a few things wrong in the mod pack that i didn't noticed yet.

Installation is pretty easy, instructions are in the note in the zip file. Instructions for updating are on the same note too.
