the suits have a lot of restrictions in terms of how your body can move, what you can actually feel or operate with your fingers. so there are a lot of challenges and restrictions for operating equipment and, as a result, for doing proper field research, so if you're not wearing a suit that is restricting some of those operations, then you don't really know how to problem solve and create the instruments that are going to be able to be operated properly in the field on either the moon or mars. scientists call landscapes which are analogous to other planets �*analogues�* and daniel leeb and gunnar gudjonsson are hoping to promote iceland to do this kind of research. so they formed a 2—person operation that they are calling the iceland space agency. iceland has some of the most diverse set of terrestrial analogues in close proximity to one another that exist anywhere on the planet.
