"A great deal of remediation" will be needed at Kitt Peak National Observatory as a few astronomers return to the site to help it recover from wildfire damage, its managing authority says.
Essential personnel are returning to the Arizona observatory to assess the damage caused by a large wildfire that ripped through the mountainous area in June, officials from the National Science Foundation's National Optical-Infrared Astronomy Research Laboratory (NOIRLab), which runs the observatory, said in a statement (opens in new tab) on Thursday (July 21).
The blaze required firefighting efforts using both helicopters and planes, which kept all the telescope domes on site standing. At least four other buildings fell to the fire. It will take the astronomers' expertise, however, to determine how much damage the facility sustained in the Contreras fire, NOIRLab officials wrote.
"Damage to interiors, especially the telescopes, instruments and other scientific infrastructure, will only be known after the telescope teams are able to spend more time on site," the release stated. "The total cost for restoring the observatory functions is also not yet known."
Conditions on the peak are by no means normal. Grid power is unavailable at the site, and likely will remain that way for several weeks as observatory staff work with the Tohono O'odham Utility Authority to put up power lines, utility poles and data services, NOIRLab's statement read.
The road to the observatory is only open to essential personnel in consultation with local emergency crews, the statement added. The public will not be able to visit until normal science operations resume and NOIRLab receives authorization from the Arizona Department of Transportation, officials said.
Kitt Peak is not the only astronomy site to face down flames, as wildfires are increasing in frequency and intensity due to ongoing, human-driven global warming. Other observatories have survived close brushes with wildfire before this one.
Examples include a California fire skirting within a few miles of the SETI (Search for Extraterrestrial Intelligence) Institute's Allen Telescope Array in September 2021, and a separate one encroaching near Mount Wilson Observatory, also in California, in September 2020.
