- It's really exciting that just right now

in the past like 50 or 60 years

we've been able to actually get off of the surface of Earth

and start exploring our own universe.

I'm Greta Studier and I'm an

engineering major at Swarthmore College.

For my senior design project, I have been working

with JPL on a future Mars mission.

The project that I've been working on

is to build storage unit that will safely

hold sample tubes on a Mars rover.

This is part of a future mission that JPL

is gonna do called the Mars Sample Return Mission,

which is basically gonna send a rover

to collect sample tubes, safely store them

on a unit, which I have been designing,

conceptual design for them for,

and then launch those samples back to Earth.

We've been sending rovers and satellites

to different planets for decades,

but the Mars Sample Return Mission

will be the first time we've brought back

samples from another planet.

The Parking Lot is another name for the storage unit

that I've been designing.

It's a temporary place for the sample tubes

to sit in while the fetch rover's driving around.

So these are my two 3D-printed test stands

for holding sample tubes.

These were both printed in the Makerspace

and they each have two different mechanisms

for retaining sample tubes.

This stand all uses clamps, so this is one clamp

and they can retain one sample tube

by just inserting it like that.

And then this stand uses spring plungers,

which basically have a ball on the end

and have a spring on the inside

so they are compressible.

So when you insert it, it'll stay there.

The main mission is to be able to analyze

Martian rock for evidence of past life.

In a rock core there could potentially be

fossils of bacteria or really tiny microbes.

Instead of relying on the capabilities of a rover on Mars

to analyze the content of Martian rock,

we could instead bring it back

and run more tests in a more robust laboratories on Earth.

My mom, when we were little,

would bring us outside to say goodnight to the moon,

so I've always been interested in space

and the unknown in parallel with my engineering interests.

Knowing what you wanna do and then executing it,

it's like a big jump sometimes.

Coming into Swarthmore I didn't know what type

of engineering I wanted to do.

And taking a bunch of different courses at Swarthmore

really exposed me to mechanical engineering and design.

And so those courses that I took here

really got me hooked.
