    "Mechjeb is an amazing mod to Kerbal! I am a real builder-type of player and I really enjoy being able to make all sorts of stuff from scratch. With this mod, I can really explore my more creative side and build weird things that I want to hehe. What I like about it is that it works as expected and it really gives something extra to the game that isn't really built into it. Really great work by the devs here!"

DID YOU KNOW?

Did you know that the scientists and engineers at NASA’s Jet Propulsion Lab are self-confessed obsessed players of Kerbal Space Program? At the 2013 Electronic Entertainment Expo, casually known as the E3 Expo, they said that for them, the appeal of the game comes from the lack of consequences and responsibility. Within the game, players can create their own rocket ships without thinking about resources such as time and money. In the game, they can try out ideas that they would never try in real life because of the possible consequences. Elon Musk, a self-taught rocket scientist and the founder of SpaceX, has also announced his love for the space flight simulation game.

The game is not a perfectly accurate simulation, but the physics behind the game has been lauded for being scientifically correct. The game employs Newtonian mechanics and Keplerian laws for orbits and maneuvers. The inaccuracies in the game, such as the scale of the solar system, are the result of the developer’s considerations for making the game not too highly technical and the limitations in computing power of the players’ computers. There are also user-created mods for the game to add new ships, new parts, new functionalities that make the game more entertaining to play.

    "I cannot consider it as one of the best kerbal mods out there since it only shows about stats which I have no interest of. I'm not saying that this mod is not good but it's just not my type. Sorry Kerbal Engineer Redux."

    "Amazing new ideas but it kindda felt like a MARVEL movie and not a real space experience anymore. It is good that new technology was added like nuclear reactors and thermal rockets, but like other ksp best mods, it could still be better."

    "Planetshine is a killer mod for the Kerbal Space Program. This is by far, my favorite lighting and visual mod. This mud helps to add Planet shine Kama which is the reflection of light from a planet on to your vessel. Now that I've used this mod, I couldn't imagine not using it. The last time I did everything looked really strange. Check it out you won't be disappointed."
