[......] But do you see the space rocks that could plunge into our planet, causing major destruction?
NASA does.
It's using a spacecraft called the Near-Earth Object Wide-field Survey Explorer, known as NEOWISE, to track near-Earth objects -- asteroids and comets -- that could hit our planet.
NEOWISE has discovered 72 new NEOs since 2013. The tally includes 8 objects that are classified as potentially hazardous asteroids -- asteroids that could one day approach or hit Earth.
NEOWISE also is helping scientists study space rocks detected earlier by ground-based telescopes. It's provided new information on a total of 439 NEOs previously detected by those telescopes.
"NEOWISE discovers large, dark, near-Earth objects, complementing our network of ground-based telescopes operating at visible-light wavelengths. On average, these objects are many hundreds of meters across," Amy Mainzer, NEOWISE principal investigator, said in a news release.
If you combine the number of NEOs spotted by the satellite with the ones identified by ground-based telescopes, a total of 14,246 NEOs had been detected as of this week.

Quiet - thankfully - but important work.
They're even trying to get their arms around some solutions if need be.. lest we go the way of the dinosaurs.

A planet killer is already out there somewhere as we speak, quietly smashing through the dark voids of space on an inevitable collision course with Earth; and the only hope for our beautiful little blue planet is technology!Quiet - thankfully - but important work.

Amanda Barnett - April 7, 2016Very important work. I am strongly in favor of coming up with solutions well before we ever need them.
I was never in the Mars fan club, seemed pretty boring, but it does hold some incites on what could happen to earth-like planets.These are why we need to shelve the Mars projects and focus on near Earth. Not only do we need to be able to protect ourselves from NEO's, we should be working on ways to take advantage of the resources they provide. We could be getting all the research benefits that people keep saying justify a Mars trip, but we are also protecting ourselves from EXTINCTION and possibly accessing resources that could make getting to Mars FAR more affordable.
Always good to see your smart, un-PC posts.A planet killer is already out there somewhere as we speak, quietly smashing through the dark voids of space on an inevitable collision course with Earth; and the only hope for our beautiful little blue planet is technology!

You betcha Big-guy! :angel?:Always good to see your smart, un-PC posts.
Glad you're still around.
The tyranny of the rocket equation may never be overcomeI was never in the Mars fan club, seemed pretty boring, but it does hold some incites on what could happen to earth-like planets.
It had water, an atmosphere, and....
Of course, growing up on Star Trek, and a watching the first moon landing, I was hoping we'd be way out there by now. Unrealistic of course, until the propulsion problem is solved, if ever.
