Using the power of Smoothed Particle Hydrodynamics let's show that it would take an impossible set of circumstances to punch a space rock all the way through the planet Earth. The problem is that simply making an object go faster adds more energy than momentum, instead you need either an impossibly dense object, or, an impossible strong object. Neutron stars can move through the earth as if it were the vacuum of space, but, then you have an object thousands of times the mass of the Earth.

The challenge is to land on the highest peak in the mountain range near the space center, I decided to go a step further and land a tower on top to make it slightly higher. http://www.reddit.com/r/KerbalSpaceProgram/comments/1j5152/weekly_challenge_k2/ ... https://www.youtube.com/watch?v=qo3iQvnisTk

A round up of big space news stories, with Blue Origin flying its first commercial mission while Elon Musk Starship Hopper falls over in high winds. We also got the details on why building the Super Heavy Booster from stainless steel was 'counter intuitive. Stratolaunch's Roc looks like it's becoming the modern equivalent of the Spruce Goose and Vector Space Systems gears up for a test launch.

Donate to the Campaign to reboot ISEE-3 - http://www.rockethub.com/42228 ISEE-3 was a spacecraft launched in 1978 which originally examined the solar wind and plasma environments around the edges of the Earth-Moon system. In the Early 80's some fancy orbital mechanics and a lunar gravity assist was used to put the spacecraft into deep space to encounter a couple of comets. Now 30 years later it's coming back to Earth and could use some more orbital mechanics trickery to bring it back into earth's orbit, the only problem is that the technology required to talk to the spacecraft has been 'retired'. So a team at Skycorp is racing against time to build a replacement and command the spacecraft back into a captured orbit. ... https://www.youtube.com/watch?v=m4D6pRT04PY
