it's hard to have a sibling who gets to
do everything first but it's different
for the Mars rover Curiosity because
its sibling Maggie does everything first
without even leaving Earth but do you
think anyone knows about her nope
curiosity is the one who gets all the
attention being the first to explore
Mars while Maggie has to do all of her
roving here on earth and I'm gonna get
to meet the scientist who's basically
the queen of Mars or at least the deputy
surface lead for Mars 2020
Diana Trujillo this is so cool welcome to the mars yard
thank you hi Maggie how's it going so
here was Maggie who's name is an acronym
for Mars automated giant gizmo for
integrated engineering but just how did
Diana manage to become the team leader
of one of the most expensive robots on
earth did she study at an Ivy League
college did she win a coolest job in the
world contest or do robots just like her
so let me tell you a little bit about my
story I came to the u.s. in 2000 I
didn't have any money and I didn't know
any English so when I got here I put
myself through college I found a way of
getting the right internships going
through college and getting the right
grades so that I can then apply to NASA
and end up working on a Mars mission
which to me is insane to know that I
went from actually working really hard
three jobs not sleeping anything and not
knowing English to actually manage a
mission on the surface of Mars wow
that's amazing so what makes Maggie so
special Maggie is the exact replica of
the rover that we have on the surface of
Mars the operations that we do are very
complicated and so we want to come here
to make sure that we can install the
arm do the drilling do the driving
that we need to do move the head take
the images do it exactly how you want to
do it because you're going to command it
from Earth and you're gonna execute it
on Mars many hours later so you don't
want to get it wrong so what exactly is
Curiosity doing on Mars so the mission
for curiosity really is to find out if
there was the chemical composition
that will sustain life so has curiosity
found anything yet well the amazing
thing is that within the first year of
the mission we found out that there was
the chemical composition that will
sustain life Diana explains that Curiosity found
evidence of organic molecules in 3 billion year old
sedimentary rocks near the surface this
is not proof that there was life on Mars
just that the conditions might have been
able to support life to replicate the
surface of Mars JPL has created this
area where many of the physical
conditions on Mars have been recreated
Diana and her team learn how to
identify and maneuver Maggie through
obstacles this information helps the
scientist program curiosity's path on
Mars and once again Maggie's sister gets
all the glory so now can I take my
selfie with Maggie of course but first
you have to get grounded wait but I
didn't do anything wrong
not that type of grounding what Diana
means by grounded is that I have to wear
a special suit that is wired to the
ground to stop static electricity from
jumping from my body to Maggie no effects were used for the scene this is actually
just how long it takes for me to put on
a jacket finally selfie time had arrived no
Mars rovers were harmed by static
electricity during the taking of this
selfie
