Q&A 51: Could We See Ourselves in the Past? And more..

What would happen if a gargantuan asteroid hit the moon? Would we see anything here on earth?
You would totally be able to see it. Amateur astronomers have spotted all kinds of meteors striking the Moon. Much smaller than gargantuan.
Do you think it is likely we will be able to create shield blocking some of solar rays in L1 point, to remedy the global warming?
I always thought it would be cool to put some solar collectors there to gather the solar rays, convert to usable power, and at the same time remedy global warming.
@ 05:06 I think the question was asking about the post-launch roll, not the fact that the path itself curves away from the pad. To that end, Amy Shira Titel's video on the topic is pretty awesome.
I was originally thinking that, but then they asked why they don't just point it directly at the target they're launching towards.
"Ahhh! Terrified!" LOL
