The Vera C. Rubin Observatoryin Chile, noticed its first photon a couple of months in the past, a monumental occasion 25 years within the making. Senior Editor Evan Ackerman’s journey to Chile, to see the observatory and speak with the workforce in regards to the a number of and large engineering challenges they overcame, itself took greater than a yr to plan.
The go to was initiated by Italian photographer Enrico Sacchettiwho had organized for unique entry to the telescope. The story we wished Ackerman to inform required greater than a fast tour. So Sacchetti and Ackerman organized to spend three nights on the summit of Cerro Pachón, sleeping in the course of the day after which staying up late with the engineers and scientists as they labored to get Rubin “on sky.”
Ackerman and Sacchetti didn’t know precisely what would occur whereas they had been there. In some methods, they received fortunate—the few days earlier than first photon had been filled with frantic exercise. In different methods, they weren’t so lucky. The dome protecting the telescope wasn’t working, the moon (bane of astronomers in every single place) was close to full, and Sacchetti got here down with an sickness that just about required him to be evacuated down the mountain.

“For a barely panicked 24 hours, I enlisted the assistance of some beginner photographers among the many Rubin employees to make it possible for we had all of the pictures that we’d want,” Ackerman says. You possibly can see a few of their wonderful work in “How the Rubin Observatory Will Reinvent Astronomy.” And Sacchetti recovered sufficient to get the essential photographs he wished.
The identical traits that make Cerro Pachón the right place for observatories could make it a difficult place to work. For Sacchetti and Ackerman, in addition to the Rubin employees, schlepping as much as the two,600-meter summit from sea degree took some adjustment. Ackerman didn’t have a lot of a bodily response to the altitude. However he realized that mentally, the skinny air hits everybody a bit of otherwise.
“I found a whole incapability to recollect schedules,” Ackerman remembers. “William O’Mullane, data-management undertaking supervisor for Rubin, informed me that for him, it’s feeling that he is aware of the reply to a query, however not what the reply truly is.”
Along with scheduled interviews with engineers and astronomers, Ackerman wandered across the management room, becoming a member of conversations that appeared attention-grabbing. The Rubin employees isn’t superstitious, however he nonetheless heard some rumors involving the native fauna.

“Recognizing a viscacha close to the observatory is sweet luck for that evening’s seeing, accurately. It seems like an aggressively cute cross between a squirrel and a rabbit, however it’s technically a sort of massive chinchilla,” he says. Much less cute are the Andean condors that reside on the cliffs close to the Southern Astrophysical Analysis Telescope, which can also be positioned on Cerro Pachón. Seeing them within the air within the night is a foul signal, Ackerman was informed, which can be considerably grounded in actuality, for the reason that thermals that the condors experience indicate turbulent air across the mountain.
Even the opposite “unfortunate” elements of the go to helped make the story higher. The total moon, whereas overpowering a lot of the sky, lit up the surface of the observatory and resulted in some implausible nighttime pictures. And the quickly nonfunctional dome led to a number of in-depth conversations about how troublesome it’s to get all of those bespoke methods to work with each other, and helped Ackerman respect the advanced job of the commissioning engineers.
