   Following the finger, the dotted red line shows the pre impact surface, and the green circle beneath it is the meteorite.

   I think Americans worry just for fun.

   Love it, especially Le Petit Prince part! Number one book in my life starting the age of 15 when we had a play – semi professional theater I was a part of…thus still remember by heart parts – translated in Russian… Also A de S-E Citadel is very intuitive as well…

   Excellent shot – amazing what such a small object can do – well relatively small.

   Random fact: That is privately owned & operated crater 😉 The family owners run the attraction/museum as a business & have the whole thing fenced off to prevent interlopers.

   We visited here on a road trip a few years ago. I was impressed with the quality of the visitor center, and the hike 1/3 of the way around was enjoyable. I love this low sun angle view of it; we were there mid-day.

   I just reread the list of priorities I heard at the Russian Federal Space Agency, and asteroid protection was there, top of the list…

   And while researching the Apollo Goodwill Disc, I found this quote from a 2001 interview at JSC:

   "it’s so small, it’s very colorful — you know, you see an ocean and gaseous layer, a little bit, just a tiny bit, of atmosphere around it. And, compared with all the other celestial objects — which, in many cases, are much more massive, more terrifying — it looks like it couldn’t put up a very good defense against a celestial onslaught." — Neil Armstrong

   And news:
   

   And the pace of progress in the discovery of NEOs using terrestrial techniques:

   Here’s an incredible dash-cam video capture of the incoming meteor in Russia…

    "just hours after the Chelyabinsk event, a much larger
    object (2012 DA14, ∼45 m diameter) passed below the geostationary
    orbits to within 27,000 km of Earth—a very close call by
    astronomical standards. The object was of a size class on par with
    the 1908 Tunguska event as well as the Canyon Diablo meteorite
    (∼50 m, 300–400 kilotons, and 20–40 megatons of impact kinetic
    energy), which produced the Barringer Crater in northern Arizona
    49,000 ya"
    So these are more frequent and large as new info has become available, in contrast to what they taught us 20 or 30 years ago.
