9 Supports Completed over the weekend (Total time: 19.7 hours)
8 SSR dumps

CAP's / Procedures Run:
CAP # | Time | Title / Description / Notes
[750AG] | 211/2054z | Low Rate Dump of the On-Line OBC Checksummed Memory (XSUM_1)
Low Rate Dump of the On-Line OBC Checksummed Memory (XSUM_1) Range (0x00000 to
0x0FFFF)
[750AH] | 212/0157z | Low Rate Dump of the On-Line OBC Checksummed Memory (XSUM_2)
Low Rate Dump of the On-Line OBC Checksummed Memory (XSUM_2) Range (0x10000 to
0x1FFFF)
[750AI] | 212/1141z | Low Rate Dump of the On-line OBC Checksummed Memory (XSUM_3)
Perform on-orbit OBC checksummed memory dump of the on-line OBC (address range
of 0x20000 to 0x2FFFF).
[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.
