On 8 October an asteroid detonated high in the atmosphere above South Sulawesi, Indonesia, releasing about as much energy as 50,000 tons of TNT, according to a NASA estimate released on Friday. That's about three times more powerful than the atomic bomb that levelled Hiroshima, making it one of the largest asteroid explosions ever observed.
No telescope spotted it before it entered Earth's atmosphere. Rather than try to return to the Moon or go to Mars I would rather build an asteroid defense system. My motto: First, don't die.
