Even individually, the ALMA antennas are impressive in size. The Chajnantor plateau itself is also located at an altitude of 5,000 meters (16,000 feet), with its Operations Support Facility (OSF) at a (still considerable) altitude of 2,900 meters (9,500 feet). As the antennas are not built up on the plateau, this required an entirely new approach to transporting each of the constituent antennas from the OSF up to Chajnantor. Enter Otto and Lore! Designed and built especially for the job, Otto and Lore are the names of the two ALMA transporters — the two yellow vehicles pictured here. The duo possess impressive features; at 20 meters (66 feet) long, 10 meters (33 feet) wide, and with 28 wheels each, these machines are built not just to survive in the harsh environment of the Atacama Desert, but to thrive in it! While rugged and powerful, they also possess a delicate touch, and are able to position each antenna with astonishing millimeter accuracy.
