this asteroid that landed in siberia or hit siberia about 100 years ago, it did a huge amount of damage. luckily it hit in siberia and hardly anybody was living there at the time, right? this is a natural disaster we actually know how to prevent. if we do the search and the warning and apply our space technology to prevent impact. we can t ward off the sudden wind storms like we had here in washington over the weekend. this is something we can change. so the real threat is there. about 30 times a year we have a hiroshima-sized explosion in the atmosphere. fortunately the asteroids burst and disintegrate farther up well above our heads. a larger one can level a city. it happens every few centuries. we have technology to do something about it. let s get started. jon: what is the technology? it is one thing to send a tell cope to try to find these things. is it something else to alter their course to push them out of the way so they don t hit earth? we haven t rehearse ad
that is for you. jon: nice. jenna: that is coming up next hour. jon: a nonprofit organization just announced plans to save the earth from asteroids. the b-612 foundation wants to map every asteroid that potentially could hit our planet. it has happened before, as recently as well, 1911 or so. an asteroid hit siberia. the impact, 1,000 times the force of the a bomb dropped on hiroshima. here is pictures of some of the trees flattened as a result of that asteroid impact. the group says a larger asteroid could have devastating effects. the sentinel will be a 1 1/2 ton, 25-foot tall infrared telescope launched into space. it would orbit our solar system to map potentially dangerous asteroids that could impact the earth. let s talk about it with tom jones a former nasa shuttle astronaut, a fox news
