so this little rock da14 is coming alarmingly close to the surface of our
alarmingly close to the surface of our
alarmingly close to the surface of our planet and we’re fortunate that it’s not
planet and we’re fortunate that it’s not
planet and we’re fortunate that it’s not going to hit us but it should serve as a
going to hit us but it should serve as a
going to hit us but it should serve as a bit of a shot across the battle from the
bit of a shot across the battle from the
bit of a shot across the battle from the solar system telling us and you gotta
solar system telling us and you gotta
solar system telling us and you gotta look out for this my name is Kevin and
look out for this my name is Kevin and
look out for this my name is Kevin and I’m a planetary scientist and
I’m a planetary scientist and
I’m a planetary scientist and astrobiologists at NASA’s Jet Propulsion
astrobiologists at NASA’s Jet Propulsion
astrobiologists at NASA’s Jet Propulsion Laboratory and it was a 2011 National
Laboratory and it was a 2011 National
Laboratory and it was a 2011 National Geographic emerging Explorer and to give
Geographic emerging Explorer and to give
Geographic emerging Explorer and to give you a sense of how close da14 is gonna
you a sense of how close da14 is gonna
you a sense of how close da14 is gonna come to the earth on February 15 it’s
come to the earth on February 15 it’s
come to the earth on February 15 it’s only 18,000 miles da14 is passing within
only 18,000 miles da14 is passing within
only 18,000 miles da14 is passing within the distance of many of our Earth
the distance of many of our Earth
the distance of many of our Earth observing and telecommunication
observing and telecommunication
observing and telecommunication satellites if this da14 were to come
satellites if this da14 were to come
satellites if this da14 were to come down and hits somewhere in a major
down and hits somewhere in a major
down and hits somewhere in a major metropolitan area hundreds of thousands
metropolitan area hundreds of thousands
metropolitan area hundreds of thousands potentially millions of people would be
potentially millions of people would be
potentially millions of people would be killed for objects that are less than
killed for objects that are less than
killed for objects that are less than 100 meters and this is the type of
100 meters and this is the type of
100 meters and this is the type of object that da14 is and the estimates
object that da14 is and the estimates
object that da14 is and the estimates are that there are more than 1 billion
are that there are more than 1 billion
are that there are more than 1 billion except such objects and so what do you
except such objects and so what do you
except such objects and so what do you do if you find one that’s on a
do if you find one that’s on a
do if you find one that’s on a trajectory that’s going to lead to a
trajectory that’s going to lead to a
trajectory that’s going to lead to a direct impact of the earth we would send
direct impact of the earth we would send
direct impact of the earth we would send some sort of chrome out to this object
some sort of chrome out to this object
some sort of chrome out to this object and that probe would either knocking do
and that probe would either knocking do
and that probe would either knocking do it or attach to it and then and then
it or attach to it and then and then
it or attach to it and then and then fire some rockets to give this the the
fire some rockets to give this the the
fire some rockets to give this the the rock a little bit of a nudge to change
rock a little bit of a nudge to change
rock a little bit of a nudge to change its trajectory once you put the thruster
its trajectory once you put the thruster
its trajectory once you put the thruster on the back end you’ve kind of got a
on the back end you’ve kind of got a
on the back end you’ve kind of got a remote-controlled asteroid we’re really
remote-controlled asteroid we’re really
remote-controlled asteroid we’re really what we need are some space-based assets
what we need are some space-based assets
what we need are some space-based assets to go and and look around in all
to go and and look around in all
to go and and look around in all directions basically to sort of serve as
directions basically to sort of serve as
directions basically to sort of serve as our as our space guard for for these
our as our space guard for for these
our as our space guard for for these objects that are hard to find and very
objects that are hard to find and very
objects that are hard to find and very populous
