House committee to hold hearing on asteroid threat
Source: The Hill
The House Science, Space and Technology Committee will hold a hearing on how to better identify and address asteroids that pose a potential threat to Earth, Chairman Lamar Smith (R-Texas) said in a statement on Friday.
The announcement comes after a meteorite exploded in a massive blast above Siberia that damaged buildings, houses and cars and injured about 1,000 people on Friday.

Todays events are a stark reminder of the need to invest in space science, Smith said. Asteroid 2012 DA14 passed just 17,000 miles from Earth, less than the distance of a round trip from New York to Sydney. And this morning, a much smaller meteorite hit near the Russian city of Chelyabinsk, damaging buildings and injuring hundreds."
"Developing technology and research that enable us to track objects like Asteroid 2012 DA14 is critical to our future," Smith said. "We should continue to invest in systems that identify threatening asteroids and develop contingencies, if needed, to change the course of an asteroid headed toward Earth.

You want to move it, change its orbit, since that's the way you get it to miss. And you can do that without what would be called a weapon if you know its orbit ahead of time.
If all one can think of are nuclear weapons to fix this, one probably has been watching too many Bruce Willis movies. At least Steve Buscemi's character got it right. "Guess what guys! It's time to embrace the horror."
It won't work.

I saw that you are for developing technology and research that would enable us to track Asteroids.
I was wondering if you were aware this would require the government to spend money. Something that Republicans oppose.
Sincerly,

(32,822 posts)I'm doing this from memory so bear with me. The asteroid that just went by will do two more safe orbits, then may hit the earth in 2060(?). If we can get something into its orbit in 2024(?) or 2048(?) we could attach a solar sail and tow it into a safe orbit so it doesn't hit us in 2060.
Cool stuff.

(40,416 posts)Asteroids rotate, just as about every other heavenly body does. Many rotate quite quickly. So any solution to move an asteroid into another orbit has to be independent of its rotation. Therefore, attaching anything to the asteroid in general won't work if you want to be able to control it so it won't hit. You want to push it into a safe orbit, not just any old orbit that isn't the one that makes it hit us in 25 years. Hell, you could push it into a different keyhole that brings the sucker into collision in 18 months. What would we do then? I guess we say, "Oopsie!"
My favorite? A gravity tug with an ion engine.

I'm sure Republicans will do their best to thwart that, and instead focus on the more important task of making sure gay people can't claim one another on their taxes.

(7,403 posts)At least Russia has said that they were aware of its presence but knowing the composition and size they didn't want to cause a panic. DA14 was something like 4 times the size so is this debate all about size?

(18,807 posts)If this one showed up about three hours later it would've exploded over Moscow and we'd be talking a hundred thousand people injured instead "just" a thousand. Some hours earlier and the same thing could've happened over China.
Try not to think too hard about something like that happening in, say, 1983.
People like to dismiss this sort of thing - look at most of the responses in this thread; DU's always been passionately Luddite about anything space-related - by claiming nothing's ever going to happen, or by just doing the "science fiction therefore fiction" thing that the press likes to do. There's a thousand Russians who are very, very lucky only to have burst eardrums and faces full of broken glass who have some opinions on that sort of attitude by now, I'm sure.

(7,403 posts)For instance, they said this meteorite was travelling at 33,500 MPH but that is relative to Earth. Earth is traveling through space at around 65,000 MPH if my math is correct. If this object was coming at earth from the opposite direction then the speed would be the sum of the two so scratch that. If the object was coming at us from a right angle then it seems to me it would have been a T-bone crash so scratch that. That leaves this object going the same direction as Earth. So was the Earth overtaking this object by 33,500 MPH or was the object overtaking the Earth by 33,500 MPH? It makes a huge difference as to the relative speed this object was moving through space.
