Slightly more impressive than habs, rovers, or even greenhouses IMO. ;-)

In other MS project News

From http://www.marssociety.org/

"The fabrication of the European Mars Analog Research Station (EuroMARS) has begun in earnest. The work, led by Project Architect Frank Schubert and funded by Starchaser Industries and the United Association of Plumbers and Pipefitters (UA), is being done on the premises of the Rio Grande company in Denver, Colorado. Fabrication is expected to be complete by the end of May 2002, after which the station will be put on display in a major public exhibit in the United States. It will then be shipped to Europe for deployment in the field in the Spring of 2003. "
