[1372B] | 213/0909z | Swap Prime SSR to Backup Every 6 months the prime SSR will be switched to the backup position. This is being done to maintain health and trending data on both SSRs for the remainder of the mission. The swap will typically be aligned with the bi-annual report periods: Feb – July = SSR-A prime Aug – Jan = SSR-B prime However, operational conditions may dictate SSR swaps at other times as well. [750AM] | 213/1957z | Low Rate Dump of the Off-Line OBC Checksummed Memory (XSUM_1) Low Rate Dump of the Off-Line OBC Checksummed Memory (XSUM_1) Range (0x00000 to 0x0FFFF) [750AK] | 214/1008z | Low Rate Dump of the Off-line OBC Checksummed Memory (XSUM_2) Perform on-orbit OBC checksummed memory dump of the off-line OBC (address range of 0x10000 to 0x1FFFF). DSN DR's Created: DR Number| Station| Problem| Cause| Action ---|---|---|---|--- [M113753] DSS-54| DSS-54 was not able to support Chandra| Antenna unable to move due to stuck elevation brake.| Fix in progress Radiation: Solar activity is expected to be very low on days one, two, and three (02 Aug, 03 Aug, 04 Aug). MP: Aug0921 loads in work. ENG: Switched SSR B as primary recorder, momentary data glitch was seen while turning on SSR B that has been seen before while turning an SSR off. We believe same mechanism is at play, no further impact is expected. GOT: No issues.
