Q&A 46 - Why Doesn't NASA Cancel SLS? And more... Featuring Emma Osborne
In this week's QA, I answer the several related questions about why NASA doesn't just cancel the Space Launch System and give all their money to SpaceX. With special guest answerer Emma Osborne.

This may sound like a dumb question, but why doesn't ice evaporate in space? Water would boil in a vacuum, wouldn't it? Or is it vacuum vs extreme low temperature, where low temperature wins?
It depends on the distance. The frost line in the Solar System is the point at which there's so much energy coming from the Sun that ice sublimates in space. Beyond that point and it stays frozen.
Hey Fraser! Have you ever watched the documentary "Seeing the Beginning of Time"? This is one of the best docu's I have ever seen and it has a good pedigree. This got me very excited about the LSST. Look it up sometime, but I suspect you've seen it already.
What, no. And it's about LSST? I'm in. I'll queue it up, thanks!
I know the SLS is kind of a money black hole. But the program kept the engineering expertise we have working and enabled new younger engineers to learn from NASA's best before they retired. Also the testing facilities are a National Technological Treasure for all future development. I believe NASA will find ways to significantly reduced cost so it's not too outrageous after a few flights. A good dream anyway.
4:07 Both "Amen!" _and_ "Hallelujah!" ~_^ For all its various flaws, the Shuttle was a truly amazing machine.
Thank you, as always, for the wonderful content!
If there was an open wormhole, say close to a large orbital body, like a planet, and there existed an equally massive or more massive body on the other side of the wormhole, would the gravity from the objects effect each other and distrupt each other’s orbit? Would gravitational effects be felt through a wormhole?
No love :(
It’s exhausting to ski ... which is high praise. To get from 7th Heaven to the base of Blackcomb takes me over 45 minutes. My thighs ache just thinking about it lol
I’m in Whistler right now ... how awesome to get a video from one of my favorite Canadians! Lol
Awesome, that's a great mountain, I've skied it many times. :-)
