RED PLANET? RED RIVER! FIELD WORKS ON THE RED-MUD FLOOD POLLUTED MARCAL RIVERSIDE: pH MEASUREMENTS BY THE HUSAR-5 NXT-BASED ROVER MODEL OF THE SZÉCHENYI ISTVÁN HIGH SCHOOL, SOPRON, HUNGARY. Lang Á. 1 ,

Summary: We reported about the 3 field works with the Husar-5 rover with pH measurements on the red-mud flood points in different regions along the Marcal river. We wanted to try how our experiment works in a real field. We learned very much how much to think in a real mission, and how important is a test on a planetary analog field. We also learned much from our failures, too. We learned that contrary to the planned and programmed works it is important to send new programs to the rover. The synchronous observa-tion of the ribbon and the standard scale came to our mind in the field work, too. The experiment building and the field work surprises and problems gave great tasks for high school students, but they enjoyed the work and learned very much. References: .
