MechJeb is an autopilot system developed for Kerbal Space Program 0.14 (http://www.kerbalspaceprogram.com) which is available for download from this thread - http://kerbalspaceprogram.com/forum/index.php?topic=8021.0 It automates many common rocket maneuvers making landing on the Mun vastly easier for players who aren't experienced pilots, you can literally point and click your way from the launch pad, to the surface of the Mun and back. Installing MechJeb is similar to other mods, download the archive and open it, copy the contents of the PARTS folder into the PARTS directory in your KSP install, then copy the MuMechLib.dll into the PLUGINS directory. This only works for the 0.14 and newer versions, so you need to have the paid version of Kerbal Space Program to try this. The Autopilot isn't as good as manual flying, but it's certainly a lot less stressful. ... https://www.youtube.com/watch?v=k-2XcW9hMgA

How did we go from no asteroids in the 17th century to 700,000 today? Did you know we only found some rocks as they hit the atmosphere? Asteroid impact video by the B612 Foundation https://b612foundation.org/ ... https://www.youtube.com/watch?v=zb6Y8r1m8ls

Rocket engines make spaceflight possible, but, testing a rocket engine for spaceflight appears to represent an engineering challenge. Engines designed to operate in a vacuum may behave differently from those operating inside an atmosphere, and you might think that no vacuum pump could extract the exhaust gasses fast enough to stop the pressure building up and ruining the test conditions. However, as it turns out building a test stand which maintains high altitude conditions is easier than you would imagine since the rocket exhaust can be exploited as part of a pumping mechanism to keep the chamber evacuated. Includes a small section of Cody's Lab showing the problems with igniting a rocket engine in a vacuum chamber. https://www.youtube.com/watch?v=76JM03a6WH4 Follow me on Twitter for more updates: https://twitter.com/DJSnM I have a discord server where I regularly turn up: https://discord.gg/zStmKbM If you really like what I do you can support me directly through Patreon https://www.patreon.com/scottmanley ... https://www.youtube.com/watch?v=hrLyzpTV7GU

Demonstrating how spacecraft capsules don't just fall through the atmosphere, but can be flown using the aerodynamic properties of the design. Stock Kerbal Space Program doesn't quite do this, but a simple edit make it possible to emulate the real thing. ... https://www.youtube.com/watch?v=HgTNzDCc0gk
