SUMMARY: Five years ago NASA began a program to discover 90% of potential Earth-crossing asteroids larger than 1 km. 60% of the 1,000 to 1,200 large Near Earth Asteroids have already been found, and the search should be complete by 2008. But objects below 1 km can still be devastating, so NASA is proposing a new survey to track hundreds of thousands of these smaller objects. The new report proposes that NASA spend $236 million over the course of 20 years to find 90% of these smaller, but still devastating, objects. Another option would be to build a space-based tracking system which would increase the cost to $397 million but cut the search time down to just seven years.

This is huge news, by the way. I really hope NASA's proposal is accepted, as it would bring enormous peace of mind.

Hey,


I think that they should be accepted and also should spent some extra money on discovering those objects faster bacause who knows, maybe nasa even get some profit off of it.

:blink: Ok, so we find all of these possibly devistating asteroids. Then what do we do with them?

If we've identified the future orbits of every rock, maybe there won't be any trouble asteroids. If there are trouble asteroids, then people can figure out how to move them. One step at a time.

It would also be good to identify the composition of these asteroids - both large and small. Mining them would then be a lot easier in the future. With the space based tracking system this could be done and kill two birds with one stone. Is this even a possibility or a simple one?
