Crew 212 Sol 11 Summary Report 16-MAY-2019

Sol: 11

Summary Title: Martian Lessons

Author’s name: Marlen Castillo Vilcahuaman

Mission Status: A-ok

Sol Activity Summary: Today was a windy day for EVAs. After asking permission to the Director (with the previous anouncement to Mission Support after an issue with pasta beating), some crew members went to the walking EVA. We’re happy to notice that, today, we kept communication all the time. Radios where performing fine and the Hab could always communicate with the EVA crew.

Look Ahead Plan: Trying to use the most of our last days in MDRS. EVA requests for tomorrow.

Anomalies in work: None.

Weather: Windy, really windy.

Crew Physical Status: A-ok

EVA: 1

Reports to be file: EVA report, Space Suit Report, Operations report, Green Hab report, Journalist report, Daily Pictures, EVA requests

Support Requested: There’s a delivery for Saturday for one of the crew members. They have sent it to the PO Box.

Notes on rovers: [From Director] cleaned all the batteries on Spirit today and checked for loose connections. The connections were very corroded but not loose. Then I checked all the cells on the batteries. They were basically fine and I added 1 gallon of distilled water to them. However, there were three cells on one battery that could not be opened unless a security bar was removed. Apparently when others had filled the batteries they thought it would be fine to just ignore those cells rather than bother with the bar. The cells were completely dry. I filled them with about 1/2 gallon of distilled water and secured the bar again. I am currently charging the rover and we will see if that battery can recover. If not, I will switch it out with one on Opportunity for the remainder of the field season.

ATV’s Used: (Honda, 300, 350.1, 350.2, 350.3)

Notes on ATVs:

HabCar used and why, where? Nothing to report.

CrewCar used and why, where? Off Campus

General notes and comments:

· The tests run this morning on EVA#11 proved unsuccessful.

· The day was spent working on experiments and doing some fixes in the Station.

Summary of internet: Nothing to report.

Summary of suits and radios: A headset was damaged during EVA#10.

Summary of Hab operations:

· We assembled the new pump in the loft and changed the water filter. The area was dried and cleaned, and the new pump has been fixed to the plywood. The new pump maintains the pressure higher than before, and this fixed the heater problem; now we have enough pressure to activate the hot water. The leak in the commander’s room is stopped, and humidity is reduced, but the damage done by the old pump will require a remaking of the ceiling.

· The Engineering airlock’s external door was tightened to facilitate opening and closing. It still needs to be slightly lifted when opening.

· A snake (oval head, sand coloured skin) was found in the tunnel to the Science Dome at 6:00 PM and run away when it saw the crew.

Summary of GreenHab operations: The hot weather required more water for the plants.

Summary of ScienceDome operations: Nothing to report.

Summary of RAM operations: sand accumulated in the past EVAs was cleaned and drones were cleaned and repaired.

Summary of any observatory issues: Nothing to report.

Summary of health and safety issues: Nothing to report.

Questions, concerns and requests to Mission Support: Burnable and Non Burnable trash is now in the Engineering airlock.

EVA Report – May 15th

Crew 212 EVA Report 15-MAY-2019

EVA #11

Author: Paolo Guardabasso

Purpose of EVA: Drone Search&Recovery scenario test

Start time: 8:30 AM

End time: 10:15 AM

Narrative: this EVA was intended to test the utility of drones in Search and Recovery missions. A dummy airplane was placed at Marble Ritual to simulate a crash landing site, and an automatic mission was planned for the Tarot drone, equipped with a camera connected to a First Person View visor in real time. The two crew members placed the ground station a few meters East of the Hab and prepared the drone for take-off. Unfortunately, the vehicle was unable to take-off and the test was cancelled, and the dummy plane recovered. These results, although unsuccessful, proved fundamental to prepare for the next EVA (planned for Friday, Sol 12), where a similar scenario will be proposed.

Destination: Hab – Marble Ritual

Coordinates (use UTM NAD27 CONUS): Sector12S Northern 4250933, Eastern 518167

Participants: Vittorio Netti (Medic), Paolo Guardabasso (Commander)

Road(s) and routes per MDRS Map: 1103

Mode of travel: Walking

Journalist Report – May 15th

Today was Sol 10.

This morning there was an EVA taken by two crew members who went to Marble ritual. The aim of the EVA was to continue on with drone testing. However, during the testing of the search and recover function with a dummy aeroplane, there was a take-off failure.

After the EVA, maintenance work was done on the Hab. The water pump was changed to prevent further leaking. After the installation the pressure increased enough to activate the hot water in the boiler. In addition the water filter was changed.

There was progress made on the processing of the all the photos of the pelican nebula and the robotic telescope finished the observations on the Western Veil Nebula. Poor weather prevented further observations in the solar telescopes. Work progresses on revising the rover, a final attempt will be made with a 2am conference tonight with the UK.

The crew continued on with their group problem solving game.

For outreach a space outfit was made for a Barbie to encourage women in STEM fields with a university in the UK.

Finally, the crew prepared homemade bread and pizza, harvesting tomatoes for both bruschetta and margarita pizza.

EVA Report – May 14th

Crew 212 Rover test EVA report 14-MAY-2019

Engineering EVA

Author: Paolo Guardabasso
Purpose of EVA: Drive test of Opportunity, Spirit, Curiosity.
Start time: 10:45
End time: 12:15

Narrative: this EVA was performed to test the three rovers in similar conditions, to verify their status; it was chosen to perform the EVA in the late morning so that temperatures simulated an EVA worst case scenario. Three crew members (the Crew Engineer Paolo, the Spacesuit engineer Camilo and the Executive Officer Vittorio) drove on Cow Dung Road 0110 about one mile north from the Hab (arriving close to the crossing with Galileo Road) and then performed a U-turn and drove south. Around 0.3 miles after, Opportunity turned off becausethe battery overheated. The driver of Opportunity mounted on Curiosity and the EVA crew proceeded south and passed the Hab, driving one more mile south. Then, they performed a U-turn and drove back to the Hab. Battery levels were verified after 1 mile, at the failure point of Opportunity (1.3 miles), after 2 and 3 miles and at the Hab. A detailed GPS map is attached.

Results:

· Opportunity: the rover stopped because of the battery overheated after about 1.3 miles. It was recovered in the late afternoon (6:30pm)

· Spirit: the rover battery dropped to 65% after only 4 miles (declared autonomy is 50 miles).

· Curiosity: the rover performed nominally throughout the mission.

A graph of the battery levels for each rover over the distance is attached.

Recommendations

· Opportunity should not be used, or only be used during early morning or late day EVAs, when the temperature is low, and never without a backup rover.

· Spirit can only be used on a maximum range of 3 miles, otherwise the battery might not be enough for the way back.

· For all the rovers, a check of radiator water levels should be run as soon as possible, to verify that the tank is filled as per the manual.
