"Bringing an asteroid back to Earth? What's that have to do with space exploration? If we were moving outward from there, and an asteroid is a good stopping point, then fine. But now it's turned into a whole planetary defense exercise at the cost of our outward exploration." -Buzz Aldrin
Between recent statements from NASA, the American Geophysical Union and Los Alamos National Laboratory, you might think that humanity is overdue for a catastrophic impact from outer space. Indeed, it’s been a long time since we’ve had one that was very destructive, and other than the 1908 Tunguska blast, we haven’t had one that even registered on the Torino Scale in millennia.
But the lack of recent events doesn’t mean that our odds of having one are increased in the near future. Quite to the contrary: they are likely a symptom of the fact that we’re living in an epoch where the odds of an impact are among the lowest they’ve ever been in human history. While the probability is still non-zero in any given year, and while space exploration and studying our Universe is of great importance, it isn’t to save our world from a killer rock from outer space.
This latest release strikes me as an attempt at Phishing the incoming president. Maybe he will throw big resources at NASA if they can convince him? The labs of course would supply the Nuclear explosive expertise, they would love to be seen in a new light.
But we need to ask ourselves: would such a strike be a catastrophe? After all, we've had many asteroid strikes as big or bigger than this.
Of course it would be a catastrophe. The news media must have catastrophes to drive their business.
Ah, but it CAN'T be, because deniers think if it happened before and we're here, it can't be a catastrophe!
It seems like what was portrait in the film called "What's your name", it could destroy the entire city.
using the wifi at the espresso bar, perhaps?
Striking of a big asteroid directly to earth is more dangerous or striking it to our moon and diviating it toward earth and the results of moon's gravity on oceans on earth
It does sound like NASA is trying to reinvent itself...again. Maybe they should hire Saturday Night Live's Mr. Bill to be their spokesman, he could cry "Oh Nooooooooooes!" right after they make their pitch before congress for funding.
NASA already has enough on their plate without asking for more. They should stick to making rocket boosters that don't blow up, and space probes don't crash into planets because of pesky programming issues.
Time to finish the Orion spacecraft design, just so we have it handy.
