On the early hours of March 16, I walked out of the Mayall 4-meter telescope at Kitt Peak, aware that the world had been gripped by the COVID-19 pandemic, but thinking I would be back for my next normal shift. After all, a facility like Kitt Peak needs maintenance and care even when things were shut down and my team, the observing associates, were one group standing by to fill that role.
As the following week wore on, plans evolved. The number of people who would be on site would be significantly scaled back. Engineers were ordered to ready the telescopes and instrumentation at the observatory for a long-term shutdown. A very small skeleton staff would come to the mountain to maintain those systems that required attention. My team would work from home.
On November 6, I returned to the Mayall telescope. I was the last operator to work during a commissioning run for the Dark Energy Spectrographic Instrument. I would be the first operator to wake up the sleeping giant and put it through its paces with some pointing and tracking tests. It turned out, after several hot, dry months, we found ourselves with a stormy weekend. Winds gusted as high as 75 miles per hour. We had fog, rain, and even snow. Despite that, we did have a few clear hours. We actually haven’t opened up the main mirror on the telescope. We only used a small pointing camera mounted to the telescope’s side, but it’s good to know the telescope still can point to targets on the sky as it’s designed to. We tracked a few targets for extended times. After my shift finishes, other observing associates will work with the DESI commissioning team to get the spectrograph itself running again. It should not be long before commissioning resumes and hopefully not long after that before the telescope begins regular science.
One thing that has been a challenge, is getting used to working within “bubbles.” As I’ve noted in posts before the shutdown, the telescope operators, DESI scientists, and any needed engineers would gather together in one big control room to do the night’s work. Since I’ve been back, I haven’t even stepped into the new Mayall control room. I’ve done all my work from the old console room, we though abandoned many months ago.
A lead observer works alone in the new console room and we communicate using conferencing software. My meals are still prepared by the Kitt Peak cafeteria, but they’re delivered to the console room before I arrive. I get to heat them up in the microwave. So my days are mostly going between my dorm room and the console room. In the few times a night I do need to venture forth, I don my mask and check on the radio to make sure I’m not going to get within six feet of another person. It’s a little awkward, but not too different from working with observers who have signed in to work from their home institutions.
All in all, it’s a challenge getting used to this “new normal” while remembering everything required to operate the telescope. Still, it’s good to resume science operations. Shakespeare’s Henry V might look at us getting ready to resume science operations and say: “I see you stand like greyhounds in the slips, Straining upon the start.”
