On behalf of the NSF, AUI and ALMA, the following persons hosted the delegation in Chile: Dr. Phil Puxley, NSF program manager; Adam Cohen, AUI president; Dr. Sean Dougherty, ALMA director; and Paulina Bocaz, AUI/NRAO representative in Chile.

The delegation visited ALMA to understand and see first hand the most sought-after astronomical observatory in history. “With more than 6,000 registered users and 1,600 proposals annually, ALMA´s images and spectra of the cool and distant Universe are continuously breaking new scientific ground,” stated Phil Puxley.

The delegation toured the array operations site at 5,000 meters (16,500 feet) above sea level, where the antennas are located. Once back at the base camp (2,900 meters/9,500 feet), they visited the laboratories, offices and living quarters and heard presentations from the ALMA deputy director, Dr. Stuartt Corder and the observatory scientist, John Carpenter.
