MDRS Log Book - January 30, 2002
Shakedown Crew Report
EVA Reports

The EVAs were preformed in the sim mode. The teams were in constant contact with the hab and reported their progress regularly. All of the EVAs were primarily test scouting missions and no serious science was performed. There no samples collected. Still, a lot was learned and we got better with each outing.

The following reports were made on the days of the EVAs with actual hab comm notes given with the last report. These notes were taken at the times indicated.

EVA 1 - 1/29/02
The EVA team consisted of Frans Blok, Bob Pohl and Klaus Totzek. Sarah Kearly handled hab comms. The weather was overcast. Temp was -3C.

The objective of this EVA was to test the local comm system and to recon the ridge to the west of the habitat.

The EVA team entered the airlock at 12:06 local time. They spent 8 minutes in the airlock and then departed the hab and headed west along a swale near the hab. The team was experiencing some radio problems but decided to proceed. Bob was doing the team's comm with the hab The team kept in communication with the hab on a 5 minute check-in basis with the exception of brief blackouts due to valleys. The team had no trouble with the suits with the exception of the fogging problem. Frans also had some problems with his radio. The team was followed by Larry, the reporter from the Philadelphia Inquirer.

The team had to cut back two times before they found a swale that lead to the top of the ridge. Frans was having radio problems and was basically without comm. When the team reached the top of the ridge they proceeded north along the ridge until they came to the rover trail that leads down from the ridge to the north of the hab.

The team lost contact briefly as they came down the hill. When they regained contact they announced their arrival and the support team prepared to bring them back in the hab. After waiting 8 minutes in the airlock, the team entered the hab.

Time was 1:46. Total time out was one hour forty minutes.

As soon as the suits were off, the team reported being very hungry. This is something that has happened in the past and shows the energy that is expended in an EVA. We talked about eating a snack before an EVA and will try it in the future. The team showed that the ridge is easily accessible by foot from the hab. We also gained insight into radio communications. We have decided to do all our EVAs on foot. The area around the hab loaded with interesting geology and needs exploring.

EVA 2 - 1/30/02
The EVA team consists of Bo Maxwell, Frank Schubert and Sarah Kearly
Frans Blok was manning the hab comms. Temp is -8C. Sky is dark.

The objective of this EVA team was to tryout a night time EVA. We were interested in the ability of the team to function in the suits in the dark using flashlights. A crew on Mars might well have to go out at night or during limited light.

The crew suited up and went into the airlock at 5:15 PM local time. After the prebreathing the team departed the hab and headed south into a outflow area near the hab. Bo took the lead with the comm and did check-in with the hab every couple minutes. We continued into the wash. It soon became dark and the Milky Way came into view. The moon was behind the low clouds to the east. There was very little light. Our eyes soon adjusted and we were able to continue while using the flashlights about 60% of the time. The team had little problems with the restrictions imposed by the suits. The team approached a dead end valley and decided to climb out of it. The hill was aprox. 20 meters. On the way up Sarah found evidence of a spring. We also found several samples of water erosion. We found that is was possible to take pictures with a flash. The team took pictures of the spring and proceed up the hill. It was steep near the top. The team was also able to navigate through several valleys by dead reckoning. The team had purposely not taken a GPS. The team took a circular route of aprox. 1.5 miles back to the hab approaching the hab from the east. Bo and Frank experienced freezing of their water lines.

Sarah, who had been drinking more water did not. The team started to experience fogging. This was much more of a problem that during the day. Our progress was slowed. The team crossed the road east of the hab close to the entrance trail to the hab. The team stopped and looked at the stars. We imagined seeing Earth in the night sky. The lights of the hab were a welcome sight as we had been out almost one and one half hours.

The crew announced its arrival to the support team in the hab and entered the airlock at 18:23 local time. After waiting 8 minutes the team entered the hab. The team experienced the same hunger pangs as the first EVA crew.

This was a very interesting EVA. The sense of isolation that we experience was much more profound than during the day. The night sky took on a whole new meaning. We were also encouraged by our mobility and ability to navigate. We would recommend that there be more night EVAs.

EVA 3 - 1/31/02
This was a four person EVA team consisting of Frans Blok, Sarah Kearly, Klaus Totzek, and Bo Maxwell. Frank Schubert was on hab comms. Temp was 9C. Sky was clear.

The object of the EVA was to explore the area east of the hab. There are several outflow areas that could contain life.

The team did a lot of self suiting this time. This worked well. Total time for suiting of four was only 35 minutes. The team left the hab at 12:23 PM. The team is on foot and is heading northeast from the hab into several outflow features. The team encountered what appeared to be water features. The team started an accent of large hill for recon. The hill turned out to be aprox. 125 meters high. The team got fatigued but was able to make it to the top of the hill. The teams fatigue seemed to evaporate when they reached their goal. Spirits rose dramatically from those of the ascent. The team took many photos. The team experienced some fogging. The simplex repeater causes the transmissions to repeat. This turned out to be a great help in understanding each other.

The following are notes taken during the EVA by Hab Comm:
12:25the team is heading east. Visible from east window.
12:32Bo is handling comm. The have encountered a area of wind erosion
