>>> Good morning and welcome to
a peek at the activity inside
the international space station
flight control room at NASA's
johnson flight center.
These are the members of the
team of flight controllers
charged with keeping an eye on
the space systems and helping
crew members work through their
schedule of activities through
the day.
The commander met his American,
Russian and Japanese crew mates
and had another busy week and
SPENT a lot of time on si EPBGS
research activities and station
mateinance and another space
walk to complete an important
upgrade to the space station's
power system.
>> Welcome to space to ground.
From its successful second space
walk to the first harvest of the
year it was a busy week on board
the space station.
ASTRONAUTs completed the second
space walk of the year.
The duospent 5:20 outside the
orbiting LABORATORY to complete
the work required to finish
battery upgrades that provides
power for the soler arrays and
replaced several external
cameras.
It completes the four year
effort to upgrade the batteries
of the power sreplacing all 48
batteries with 24 new litheium
ion batteries.
Two new space walk, planned for
the early spinning.
Victor glover will be joined by
Kate and they will prepare the
station for the future
implementation of SOLAR arrays.
It was also harvest time for the
ON-GOING vegitage system.
They take -- vegetable system.
They cultivate and grow
vegetables and plants at micro
gravity.
Mike Hopkins noticed some of the
plantses were struggling to
survive.
Some of the mustards growing in
pods two PHREUPBT pillows
containing red romaine and
lettuce seeds were growing well
behind the other plantses.
In mid-January it was decided
the crew would perform the first
ever space transplant moving
them.
On earth this would be risky for
plants, but this first cosmic
transplant was successful and
all the sprouts were healthy and
ready for this week's harvest.
And that's space to ground for
this week.
Thanks for watching.
We'll see you next week.

>> The ASTRONAUTs and
cosMONoughts on the
international space station
seven as the LABORATORY
ASSISTANTs for RESEARCHers on
earth LOOKING bo a wide range of
SCIENTIFIC concepts inlewding
some we have to use to return
ASTRONAUTs to the moon for the
Artemis program.
We have to learn how to interact
with regolith and we are using
the heRmes to see how they move
over a long period of time.
>> You see this LAYER of
regolith, this fine dust that
covers the entire system.
We havastoids and meterroids and
the surface is getting bombarded
all the time.
Why would we want to steady it
and on the space station in
there is a lot of interest in
sending ASTRONAUTs to ASTEROIDs
& every time we go we learn more
and more.
Every ASTEROID seems to be
different.
We need to understand how to
interact with the ASTEROID
surface.
IF YOU ARE going to ENTERthe
surface you need to know how to
interact with the regolith.
They have micro gravity levels
of gravity.
This is what you find on the
space station as well.
There are four experiments and
each is a tube about the size of
a pringles can.
The main piece of data we are
getting is the movement of the
particles.
A camera LOOKING at each tube.
We are LOOKING at the long-term
effects of micro gravity.
Something we have on ASTEROID
system vacuum am we want to
EXPOSE them to the vacuum of
space and have our facility
hooked up to a port to space.
The idea is it will be open to
other investigate, CAsass 2, 3,
7 and they will do regolith and
granular material
investigations.
We think it is a good place to
explore regolith and are excited
for what it will bring to
RESEARCHers in the future.
>> Part of the science mission
of the international space
station to take use of
weightlessness for example the
station is home to a threed
printer that can make things and
then recycle them and 3d print
new things using the same
plastic.
>> The refabricater.
PRESENTED by science at NASA.
While 3d printer is technology
people are familiar with, there
one on the iss unlike anything
currently found on earth.
It's known as the refab
riicator, a HYBRID 3d printer
that can recycle its material to
make new things.
NASA's manufacturing manager
says recyclers on earth grind
plastic pellets to create their
products.
But that grinding creates
material shear that prevents you
from reusing it again.
It's no longer strong enough.
For this technology
demonstration the COMPANY
developed a novel RECYCLING
process that doesn't require
grinding and that allows us to
recycle the plastic multiple
times.
The ability to reuse the plastic
over and over again is essential
for long-term space EXPLORATION.
They say we can replace a lot of
the things we need when we orbit
above earth.
But in deep space you don't have
the option you have to have the
ability to make all the parts
you might need and without
having a large STOCKPILE of
extra materials.
It can even recycle plastic
ITEMs not normally ASSOCIATed
with earth bound 3d printers.
Almost all of the materials
delivered to the station are
packed using foam or plastic
bags.
Both can be loaded into the
refabricators to create a eating
utensil or custom made wrench.
That limits the Amount of back
up materials you need to take
with you.
After all, in space, space is at
a premium.
The refabricator will be two
face, they will perform seven
cycles of printing and
RECYCLING.
They will be sent back to earth
for testing and analysis to
determine the EFFECTs of
repeated RECYCLING on the
material properties of the
plastic.
He notes I'm very excited about
the technology in space and back
on earth.
I can envision a day where you
go to the grocery store and drop
your water bottles and plastic
into a refabricator and select
your new phone case or select
a kitchen gadget or filament you
use in your 3d printer at home.

>> The ASTRONAUTs on the
international space station
spent a good chunk of their time
as lab assistants on EXperiments
in a whole range of disciplines.
They also devote time to sharing
the experience of space flight
with people on the ground,
particularly whether they talk
with students and their teachers
about science, technology,
ENGINEERing and math.
We get into the difference
between kinetic energy and
POTENTIAL energy and
demonstrates how one can become
the other.
♪
>> Welcome to the international
space station.
Today we're going to talk about
POTENTIAL and kinetic energy.
Let's get started.
Kinetic energy is the energy an
object has because of its
motion.
An object can store energy based
on its position.
This is called POTENTIAL energy.
On earth million dropping an
object from a raised position.
As the altitude increases,
gravitational POTENTIAL
increase.
The POTENTIAL manager stored is
now being converted to kinetic
energy.
We also observe this with
elastic POTENTIAL energy.
>> New term.
Elastic POTENTIAL energy occurs
when objects are compressed and
stretched or deformed in any
MANNER creating POTENTIAL other
in.
Think of this spring.
Okay, what's next?
>> We pull back on the band and
create POTENTIAL energy.
When we release the to PEPBL
energy on -- POTENTIAL energy it
is converted to kinetic energy
am we are still under the
influence of GRAVITT because of
our position with the earth.
When I have this ball on the ram
normally on earth I release the
ball and it rolls down the ramp.
It is being transferred to
kinetic energy.
YOU CAN SEE it doesn't happen
here.
It doesn't mean we don't have
POTENTIAL energy Tjust means we
are not converting it at this
time to conetic energy.
-- kinetic energy.
Why?
Gravity is pulling us down.
We are moving super fast.
We are bending around the EARTH
in this motion.
Thank you for joining me on
board the international space
station.
We are sending you back to earth
to try your own EXperiments.
See you next time.
