A new $1.6-million infrared telescope with a 92-in-dia. mirror (the world's largest) to be installed soon in an observatory atop 9656-ft Jelm Mt. in Wyo. would be sensitive enough to measure the heat of a warm iron on the moon, according to Today newspaper. Professors Robert Gehrz and John Hackwell of the Univ. of Wyo. had supervised design of the telescope, which would incorporate a sensor also of their design: a computerized device sensing heat energy collected by the large mirror and converting it to an infrared contour chart depicting heat intensity as a topographical contour map would depict terrain. Jelm Mt.
was considered the best site for the observatory because of the low water vapor in the area, a requirement for good IR reception. The two scientists had persuaded the state legislature of Wyo. in 1975 to appropriate $975 000 for the project; remaining funds had come from the Natl. Science Foundation. (Today, June 12/77, 12A)
