To the editors:

After reading numerous articles about the Biosphere II project in Arizona recently (Newsweek, Discover, Chicago Tribune, etc), it is encouraging to see Harold Henderson's "A Spinach Plant Grows in De Kalb" (September 4) about controlled environment agriculture research being conducted nearby.

In considering the applications of such research to space agriculture, it might be noted that NASA is involved with its Controlled Ecological Life Support Systems program. Among others, one participant is the Horticulture Department at UW-Madison.

The September 1986 Fusion Technology article, which described the moon as a source of 3He fusion energy, may accelerate efforts to utilize lunar resources. It is significant to see these two areas of space research pursued at the same university.
