I wonder what it's made out of to survive even getting remotely close to the sun...

Scientists say they now have a clearer picture of the post-comet catastrophe on Earth:

Yep the shit an impactor actually hits will have a huge impact (lol) on the environmental effects. Compare Chixulub with Manicouagan in Quebec, both craters with roughly the same size. The Manicouagan impactor hit a bit pile of bullshit granites, so it didn't pump much into the atmosphere save for silicate dust, which would have been crap for a couple of years but caused nary a ripple in the wider sedimentary record. Whereas the Chixulub impactor hit limestones and evaporites, essentially vapourising the lot into CO2 and SO2 which caused all sorts of long-term knock-on bollox in the atmosphere and oceans.

Almost 3 years after I created this thread in anticipation of the SLS test flight and debut of the Orion capsule, inevitable delays, part of NASA's culture, have pushed the first manned flight, EM-1, to a probable launch date of June, 2020.
