Science Report

Sol 18

Experiment: Optinvent AR Glasses
Person filling in the Report: Louis Maller

Today the glasses were taken on a non-verbal EVA, worn by Arthur Lillo. They were connected to my computer in the Hab by LAN, so I could access to the glasses camera, and the files inside the glasses.

Today’s EVA was to be done without any radio comm from and between the EVA buddies (they could only receive instructions from the Hab). So the glasses were quite useful as they allowed to monitor their activities, see what they were doing.

A screenshot of the image was used to get to know the level of water inside the tank.

Head movement detection was used to record a certain amount of information using the voice record function. I was able to access the files from inside the hab as soon as they had been recorded (or as soon as the glasses were back in range), so that way we had information of the level of the two trailer tanks, gasoline tank, propane, and state of Deimos with only a slight lag.

When the crew went to check propane, the signal was lost. When they came back, we instructed the glasses’ bearer to nod in order to relaunch AirDroid. It worked, so I regained signal and was able to access to the data that had been stored.

From inside the hab it was quite a success.

I could see on the camera that Arthur was frequently using his glove in front of his face, in order to better see the screen of the glasses, so the visibility of the notifications is still an issue. Arthur told me that indeed it would have been nice to have a continuous signal on the screen indicating that the recording is ongoing.
There are a few instances when the recording ran to its maximum time (5:17).

The movements necessary to launch these actions are also new to him, so sometimes I think he moved maybe with too much or too little amplitude, and of course being in the helmet and wearing the backpack make some of these movements difficult. His feedback is that the movements should be easier to do inside the helmet. The difficulty with that is that the movement should not be so easy to do that they would be done accidently all the time. I think also what lacked is training to properly do the movements in an efficient way.

The glasses are connected to a portable battery charger, so they should not run out of charge at all during the EVA, nor display the battery alert prompter at any time.

They came back near to the hab at around 1000 and I could regain connection with the glasses, see through the camera and download files.
The quality of the recording is all right, even though the reverberation in the helmet can make it hard to understand, and it is worse when there is wind.

Experiment: Seismometer
Person filling in the report: Mouadh Bouayad
The seismometer has been recovered today from its place, and the hole it was in filled in. The data was recovered with it and analyzed in the days to come.

Experiment: Solar Balloon
Person filling in the report: Simon Bouriat
The EVA today recovered the balloon’s anchor, and the part of the platform to which it was attached. We can therefore conclude that it detached from the rest of the platform, as the balloon drifted away.
