The Large Millimeter Telescope being built 270 kilometers southeast of Mexico City on Sierra Negra is behind schedule and over budget, yet the scientists involved are upbeat.

A collaboration between Mexico’s National Institute of Astrophysics, Optics, and Electronics and the University of Massachusetts at Amherst, the 50-meter LMT was supposed to come online this year (see Physics Today, Physics Today 0031-9228 40

 April 1997, page 56 ). Now the world’s biggest single-dish millimeter telescope is expected to be completed in 2004, and its cost has climbed from $50 million to $86 million. Project scientist Pete Schloerb of UMass says the technical changes—better reflector panels and a switch to an open-air design—that are largely responsible for the delays and increased cost will pay off scientifically.

Radio astronomers plan to use the LMT to detect and study galaxies in all stages of evolution, measuring spectral lines from...
