Rubin Observatory has a complete telescope

Last week, summit staff successfully installed Rubin Observatory's combined primary/tertiary mirror 🤩
With all three mirrors and the commissioning camera now in place, we officially-for the first time in 15 years of construction-have a complete telescope! Next step: get this telescope on-sky!🌌
This isn't the telescope's final form though. This iteration has the commissioning camera - a smaller 144-megapixel version of Rubin's huge, 3200-megapixel camera - which is used for testing and troubleshooting.
Rubin's LSST Camera, the biggest digital camera in the world that will #CaptureTheCosmos in science operations, will be installed early next year after our summit staff complete the next round of tests.
Congratulations to the #RubinTeam, and major thanks to our incredible summit staff for all of their hard work!
