I am late with this. I just learned from this tweet by Neil deGrasse Tyson that yesterday was asteroid day.
The campaign wants to increase funding for finding near earth objects by a factor of 100. An impact of the Tunguska event scale near some city would be major bad news.
I write about this since it gives me an excuse to link to my global warming bitcoin asteroid science fiction novel “Last Week“, which has an asteroid impact as one of its basic elements.
