Moho is one of the hardest places to land in Kerbal Space Program, in addition to needing lots of delta-v to actually get there it has an atmosphere which will cause your engines to overheat. I try to cover what you need to know to make the actual landing and return as easy as possible. Kerbal Space Program is an indie game developed by Squad, download it from http://www.kerbalspaceprogram.com ... https://www.youtube.com/watch?v=U_r3A6M4tLE

The Stratospheric Observatory For Infrared Astronomy (SOFIA) is a marvel of modern engineering, a 2.5 Meter Infrared telescope flying in a specially modified 747, able to fly high above the water vapour that makes IR astronomy almost impossible for ground based observatories. This facility is a joint project between NASA and DLR and is based out of the Armstrong flight research center in California. However making a telescope that can fly in a plane and still be stable enough to do the required science is an engineering challenge. It's one that's solved by smart engineering rather than just brute force active gimbal control, a solution which Thanos would approve of.
