on March 7 2018 NASA planetary scientist Marc Fries
watched on a weather plunged into the Pacific Ocean four
months later on July 2nd fries and a group of marine researchers plan to pull
these meteorites chunks of primordial space rocks out of the sea no one has
ever retrieved a meteorite from the ocean before he said but the effort is
well worth it these particular space rocks he noted are different this one is
special said Fries in an interview this one is tougher than
your typical meteor the meteorite fall one of the largest fries has observed on
weather radar going back to the 90s involved space rocks that didn't break
crack will burn apart in the atmosphere as much as meteorites usually do but
understanding exactly what they are and where they came from
means visiting the seafloor where the heavy space rocks invariably sank
fortunately for NASA an exploration vessel called the Nautilus operated by
the ocean exploration trust happens to be probing the ocean depths around this
very area this summer off the Washington coast on Friday Fry's headed out to meet
scientists aboard the Nautilus the goal is to find whatever we can Nicole Ray
melt a marine scientist and ocean exploration trust
expedition leader on the Nautilus said in an interview finding meteorites
lodged in the muddy ocean floor may at first thought seem unrealistic but Fries
has narrowed down the meteorite fall to a one square kilometer area where the
ocean is about 100 metres 330 feet deep it's a pretty small area and pretty
shallow said Raine alt the Nautilus is equipped with deep-sea robots known as
remote operated vehicles (ROVs) that are designed to scour the ocean floor with
cameras and other equipment the RAAF's will be outfitted with magnetic ones
which will scan the floor for magnetic objects as some 90 percent of meteorites
are iron rich and magnetic sonar like instruments on the ship called back scan
we'll bounce signals off the seafloor to try and spot any hard objects down there
the harder the material the stronger the signal sent back to scientists above but
in the end fries says that the less technologically advanced technique of
just looking at the sea floor through the Roth's cameras may lead researchers
to these recently crashed space rocks the best tools our eyes said fries we're
going to look for rocks that don't belong there what they find could give
scientists and NASA a better idea of the type of meteorites that will inevitably
continue to bombard our planet many small but some big it will be important
for us to know what to expect to hit the ground in the future said fries in 2013
an asteroid over 50 feet across and weighing some 10,000 metric tons slammed
into Russia unexpectedly it was a meteor strike the most powerful since the
Tunguska event of 1908 bill Cooke of NASA's meteoroid environment office said
after the event in 1908 a large meteor burned up in Earth's atmosphere before
colliding into Siberia releasing energy equivalent to about 185 Hiroshima bombs
according to NASA fries and rain out seemed confident they'll find something
in the ocean even though this feat has never been accomplished before on the
weather radar fries picked up a meteorite as large as 10 pounds and 12
centimeters across however peanuts that could be larger
chunks of rock as weather radars aren't designed to pick up big metallic objects
they're made to track smaller particles in the atmosphere but even if this early
July 2nd different which you can tune into and watch online doesn't find what
Fry's is looking for it won't be a failed mission exploration is inherently
uncertain but the rewards valuable it's an exploration vessel so we are willing
to take risks to make some exciting discoveries said rain alt
