Over the previous couple days, we worked to make Theo externally complete. The goal was to be ready to transfer the first cryogens. This included preparing vacuum/fill plumbing, preapring the cryogenic thermometer readout (aka housekeeping), and generally attaching things to Theo.
Theo also had to be tipped to a lower elevation, which makes her seem a lot more like a telescope.
