architecture-design · 2026-10-06

Arquine has released a detailed account of a journey to the Gran Telescopio Milimétrico (GTM) located on Sierra Negra in Puebla, Mexico. The adventure begins at 05:15 in Sierra de las Cruces, as a convoy ascends from 2,500 meters above sea level through the Valley of Mexico and into Puebla. The writer highlights the volcanoes Iztaccíhuatl, Popocatépetl, Matlacueye, and Citlaltépetl, referencing Tlaloc and additional deities. At 08:10, the group faces delays at the Amozoc toll booth and later reconvenes with local officials and INAOE at Atzitzintla. They reach the peak at 11:40. Criticism arises regarding the GTM's dish being outdated. Engineer Dave explains the telescope's functions inside. The visit wraps up at 15:30, followed by a drone photo at 16:00. A second part is postponed.
