We went to Tuscon after a show early in the year. The weather was very nice and we had a good time exploring this city. We like Tuscon a lot. Kitt Peak evening program was a high point as it usually is. DJ and I did an overnight program there in the early ‘90’s and were on Google for a while with our photo of M73. Bruce did the program and I took photos. A good arrangement.

The Biosphere is an amazing place. I remember when it was opened and I’d hoped to be able to go and visit some day. Today was that day.

In the 1800s, the Biosphere 2 property was part of the Samaniego CDO Ranch. After several changes of ownership, it became a conference center in the 1960s and 1970s, first for Motorola, then for The University of Arizona. Space Biospheres Ventures bought the property in 1984 and began construction of the current facility in 1986 to research and develop self-sustaining space-colonization technology.

The enclosure now serves as a tool to support research already underway by UA scientists. As a laboratory for large-scale projects, such as the LANDSCAPE EVOLUTION OBSERVATORY (LEO), the university’s stewardship of Biosphere 2 will allow the UA to perform key experiments aimed at quantifying some of the consequences of global climate change.
