Minor quibble. On answering the question by KernowZac concerning the possible effects of the climate emergency on space exploration, a picture of three cooling towers is shown. I sure the vapors arising from the towers are water vapor. While the vapors may reflect cooling of heat from a polluting heat generating source, I don't believe they are polluting in themselves. I believe the use of that image in that context is disingenuous. I may be misinformed, but I am not aware that cooling towers are a significant source of greenhouse gases. By the way, I really enjoy your Q&A presentations.
Thanks Errol, I'll pass that along to Chad.
Probably a really bad idea, but: Would it be possible to dump an ice-asteroid in Sahara without causing too much damage?
There's no way to slow it down, so it would be like setting off a nuclear bomb.
