Dr. Miller delivered supplies including tardigrade handbooks, PVA medium, an Irwin loop, and a petri dish. Christina used these supplies to isolate a tardigrade under the microscope and identify it as Ramazzottius based on its claw shape. The document discusses the different filters available on the digital microscope and how they can be used to see different things depending on the light source. It provides an update on the follow-up proposal, including phone calls made to potential collaborators. More supplies were purchased to continue building the plate scanner, though completing it will require reprinting parts and buying duplicate supplies. The current progress on the half-built plate scanner is summarized. Group members provide self-ratings for

3. Dr. Miller’s
delivery
Dr. Miller’s delivery of
supplies came. He sent:
- 2 tardigrade
handbooks
- PVA MTNG
Medium
- Irwin loop
- Small petri dish
With his supplies, Christina was
able to catch a tardigrade and
put it into the PVA to create a
tardigrade slide.

4. Christina found a tardigrade and isolated it between microscope slides. She
was able to determine that it was of the genus Ramazzottius based on the
observed shape of the claws (this was also confirmed with Dr. Miller).

the digital
microscope

The color filters can be used to look at
different things. With some filters, you can
see a certain thing and with others that thing
is not visible. The filters will also work
differently depending on the light source
being used.

Proposal is almost done. The only thing
left to finalize it is the list of supplies,
which we cannot do until we have
come up with a full space habitat
design.

10. Phone calls
Steve Heck (Blue Origin) → call went well, we
now have a better understanding of what we are
dealing with in terms of the Blue Origin
microgravity flights
Ron Goedendorp (NanoRacks) → We have a
call with Ron on Friday at 1:45pm.
Traci Parker (Silicon Valley Space Center) →
we spoke a little bit about what we have done so
far, grants, and she connected us with Danielle (a
potential funder)

11. Plate
scanner
More supplies were bought:
- Cables ($7.29)
- Bread board ($8.99)
- Motor shield ($7.99)
In order to completely finish the plate
scanner, all the supplies bought will
need to be bought again to create the
top layer (y-axis) of the plate scanner.
Plan to finish: We will 3D print all the
needed parts ahead of time and then
buy the supplies. Mark will bring it
home and work on it between blocks.
Group members can collaborate to
work.

Plate Scanner So
Far…
We have completed half of our
plate scanner. The parts we have
include…
- Stepper Motor #1
- Arduino #2
- Motor Shield #3
- Breadboard #4
- Bearings #5
- Steel rods #6
- Jumper cables #7
- 3D printed connector #8

13. Christina - 9 (We got what we needed to get done, done. Though the
building of the plate scanner is coming along a bit slower than expected
because of how long 3D printing takes)
Remy - 9 (We were able to assemble half of the plate scanner. We
were also able to successfully connect the arduino to the stepper motor)
Mark - 9 (Fun week, we finished the plate scanner bottom piece and
made lots of progress with the arduino and stepper motor.)
Jake - 8 (We were able to get a lot done. However I could tell we were
all stressed out. I do think we have gotten quite a lot accomplished.)
Drew - 9 (we were able to get a good amount of work done. I wish that
we were able to get the plante scanner done on time.)
How we feel about this week…
