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.

Crew 212 EVA Report 14-MAY-2019

EVA #010

Author: Zoe Townsend

Purpose of EVA: Collection of sand samples for contaminants.

Start time: 16:30

End time: 18:45 (late and extended to rescue Opportunity)

Narrative:

Today’s EVA was to collect sand for containments. The results of which will be postposed back on Earth. Prior to the EVA, the team were contacted by Shannon to explain that part of the road was unpassable, the decision was taken to walk from Zubin’s head. Due to the heat the EVA was reduced from 2 hours to one and a half starting half an hour later.

During the EVA, the crew required a lot of equipment to prevent contamination of the samples. Therefore, the decision was taken to first scout the area and then once the location was decided to conduct the sample extraction. An unfortunate run in with non sim personal delayed the start of the extracted where there was persistence to take photos of the crew.

Throughout sand extraction communication came through from the Hab and whist the crew tried to communicate apparently the Hab could not hear the responses. The crew returned to the rover and headed back to base. Unfortunately, due to a combination of the delayed start, non sim personal and walking instead of driving the sim overran and without stable communication the Hab decided that emergency measures where required. Shannon headed toward the sight and caught up with the team returning to the Hab. After establishing the issues with the radios it was decided the crew was healthy and the situation was stable. It was then decided that the crew would collect Opportunity from it position after the Engineering EVA.

The debrief was extensive and these are the results:

  • · That upon arriving at any sight, confirmation must be made that the crew are in radio contact.
  • · Timings must be adhered too
  • · That all personal must be present prior to EVA to help with ensuring the embarking crew have all equipment required
  • · A check list of equipment will be adhered to or else the EVA will be stopped
  • · A briefing before all EVAs is compulsory.

Journalist Report – May 14th

Good evening,

Today was Sol 9.

Today started with an engineering EVA to test the performance of the rovers; there have been issues with Spirits battery and Opportunities overheating. This involved traveling a total of 4 miles; the EVA was taken at 11am to try to access the rovers in the worst case scenario, midday heat. Curiosity performed fine, however Opportunity overheated after only 1.3miles and Spirits battery dramatically discharged.

In addition crew members cleaned and assessed the damage of the X-5 rover, the data from the black box was assessed to help with the next iteration of drone.

Another EVA was taken to establish contaminants in the sand, his was undertaken by Zubin’s head. The EVA whilst successful in terms of experimental point of view, there was difficulties with communicating with the Hab and due to a road being blocked the EVA was taken by walking, this involved an unfortunate oversight in timing and combined with the communication issues caused a panic in the Hab. This situation is detailed in the EVA report.

Kind Regards,

Zoe Townsend

journalist Report- May 02nd

Today was our eleventh simulation day. The commander and vice-commander began the day with a nice morning EVA along the Hab Ridge Road. The rest of the Crew woke up at 7:30 am and we had breakfast at 8:00.

After the breakfast, the commander and vice-commander deployed their respective experiment during an engineering EVA while the rest of the team finalized their own experiments.

The deployment was postponed to this morning as different minor bugs prevented us to do it yesterday evening.The GreenHab officer harvested the Spirulina that was growing since more than a week and started to dry it.

Before lunch, the crew worked on their experiments.

At 12 am, Maxime prepared the lunch. After meal, we wanted to discuss about Nathan’s experience and his martian constitution but Chloé had to work on her experiment.

At 5pm, Nathan, Maxime, Chloé and Julien went to EVA to Grey Moon. They came back to the station at 6:30pm.

After that, we prepared the Cap Com. Each of us is working on his report and is going to send it between 7 to 9 pm. We will eat rice with tomatoes.

Like usual, we will do a crew meeting to speak about the day.

Tonight we will all observe the stars, enjoying the clear sky that the Utah offers.
