From: Chang, Lawrence (Peraton) (US Person) Sent: Monday, July 30, 2018 3:58 PM To: ivs-ops@lists.nasa.gov Subject: KPGO 20M R1853 Cryogenic Issues Aloha All, Due to a power outage, our compressor had a hard time turning back on and lost vacuum in the dewar. We currently have the vacuum pump running. We will resume the R1853 as soon as dewar temperatures and vacuum reach nominal levels.
