3D Printing Projects

Today is the last full day of MDRS for myself and our crew HSO. Our 3D-printing experiments continue to progress. We have completed printing all of our labware, International Space Station medical inventory items, STEM teaching aids, and are now printing some things here and there around MDRS, as well as other miscellaneous 3D printed projects.

To date, we have printed:

1. Western blot combs (18 well combs for making gels)
2. Microscope slide holder (reusable holder for square coverslips)
3. Sieve mesh (2.0mm holes)
4. Sieve structure (for holding the mesh net)
5. Mobile phone microscope clip
6. Sample box (for 96 tubes)
7. Stackable freezer bin
8. Salt spray chamber drain
9. Triangular straws (in a rainbow of colors)
10. Sieve mesh (5.0mm holes)
11. Sieve structure (for holding the mesh net)
12. Slide box holder (for storing microscope glass slides)
13. Test tube rack
14. Test tube holder
15. Sample rotator components
16. Small test tube holder (for the freezer)
17. Heat gun nozzle mount
18. Tongue depressors (in a rainbow of colors)
19. Stoma bag clip (used as a chip bag clip)
20. Full set of fraction tools (mathematics educational tools)
21. Funnels (small, medium, large)
22. Construction blocks
23. 12 tube separator (for Eppendorf tubes)
24. The side part of thoracentesis trainer
25. Customized finger splint (originally printed on the ISS0

During our time at MDRS, our 3D printed straws proved incredibly useful for our crew members. It has helped greatly in our attempts to reduce our water consumption. At MDRS, we have also demonstrated that a number of our 3D printed labware items are functional – as validated by two basic science research students.

Even though we will be leaving tomorrow morning, we will continue to stay in contact with our MDRS crew members and send 3D printable files for incoming crew members to print! (Perhaps some reusable bubble tea straws?)

Crew 207 EVA Report 20 Mar 2019

EVA #7

Author: Julielynn Wong

Purpose of EVA: Allow novice drone pilots to compare a standard versus novel controller to fly a camera drone in a square test flight pattern.

Start time: 14:40
End time: 16:40

Narrative: The weather was clear and sunny.

Two EVA Team members flew the traditional controller first for a test flight in a square configuration (60 ft for each side) at an altitude of 20 feet. Then the EVA team member flew a novel controller for the same square flight test pattern. XO also use the novel controller to conduct a habitat roof inspection. A post-flight survey was completed by all EVA team members.

Destination: MDRS sign

Sol Activity Summary:

Yesterday evening, COM continued data collection for the thoracentesis study.

This morning’s EVA successfully completed two additional drone mapping flights of MDRS. This afternoon’s EVA completed flight testing of a square (60 feet) flight pattern at an altitude of 20 feet using a traditional and new drone controller by two drone pilots. The third pilot conducted a habitat roof inspection with the new controller.

A post-flight survey was completed.

HSO + SCI continued 3D printing items in Level 1 of the Hab and tested their 3D printed labware in the Science Dome.

Look ahead plan: Clean up MDRS this evening for inspection. We will break sim tomorrow and transport two crew members (HSO + SCI) to GJT on Sol 8. ENG + GHO to depart on Sol 10. Mission summary to follow later on this week.

Journalist Report – March 23rd

Journalist Report March 23, 2019

Journalist: Diane Rothberg

A busy last day of simulation with two EVAs, both of which were similar to yesterday’s.

This morning, we had a great time stumbling up a hill near Pooh’s Corners with our expensive drone and controller, trying not to destroy them. But we were rewarded with a perfect launch site and a gorgeous view. Our camera drone flew its programmed route well and allowed us to keep it in sight at all times.

Tiffany and Kevin were busy in the Science Dome testing out the 3D printed labware they printed at MDRS using biodegradable plastic. The good news is that our colorful devices worked and looked fabulous!

During this afternoon’s EVA, Tiffany got a chance to fly a drone for the first time, and we both performed the control stick comparison. No contest! The new controller is much more intuitive than the traditional controller, and made a clumsy newbie like me feel like a “drone virtuoso!”

After dinner, we are wrapping up the thoracentesis data collection for our crew, and cleaning up MDRS for inspection.

Our last dinner together will be quite ethnic… potato latkes and lentil soup, concluding with one of Tiffany’s excellent desserts…. apple pie “a la Mars.”
