Good afternoon team,

 

   On the first perigee pass, we loaded the sweep tables and encountered an issue with string Ibex-1 on maestro. We switched to Ibex-3 and were able to complete the upload and the rest of the pass was nominal. For the second perigee pass, the ground station in Alaska had some issues linking to the spacecraft, but USN was able to solve the issue halfway through the pass and we got AOS at 20:30z, 30 minutes after our scheduled AOS. We came up at 320k so we were able to dump ssr data and upload the ATS for orbit 652. We performed the following, load sweep tables, dump SSR (VCid2), upload ATS for orbit 652 and reset master timer. The inertial maneuver was successful.

 

Tasks Accomplished:

Load sweep tables (CAR#1395)

Reset Master Timer

SSR Dump (VC2)

CAR #1396 Orbit 652 ATS upload

   IBEX_2024_171_o0652a_v002 - 96 commands
