Science Report
EVA Proposed Plan SOL 5 – We had to cancel the EVA for SOL 4 due to the inclement weather here at the HAB. For SOL 5 we propose the same format of EVA as SOL 3 but for the other three crew members who did not set out on SOL 3 (Geoffrey, Brittany and Sean). They will go to the dinosaur quarry and explore via rover. They will also take a GPS and map in order to gauge how easy it is to navigate to a precise location. The coordinates of this final location are the same as SOL 3: Northing: 4257412, Easting: 518238 Zone 12S.

Geology: Today no one had an EVA due to the inclement weather. We noticed that over the past 24 hours the temperature has remained very constant due to these clouds that have been around. The air has also spiked in humidity this afternoon which could be a factor in keeping the daily temperatures stable. The temperatures in the GreenHAB have also remained steady. The desired temp is 75 in the GreenHAB all the time, so this is an improvement from the wild temperature fluctuations the first couple days.

An interesting observation is that even though today the solar radiation was lower due to the clouds, the UV flux stayed about the same as past days. Proof that even on a cloudy day you need sunscreen!

The barometric pressure is lower today and has been dropping slightly this afternoon.
