MARCI was power-cycled on 4/3/2020 (off at 16:37 SCET, on at 18:12) to reset the hard partition back to empty. MROM_0968 through MROM_0992: These 25 volumes contain improved or never-before-archived images acquired from September 2006 to February 2015. The never-before-archived images are: G09_021548_2466_MA_00N332W.IMG G09_021548_2466_MU_00N332W.IMG G12_022800_3071_MA_00N314W.IMG G12_022800_3071_MU_00N314W.IMG G17_024973_0341_MA_00N239W.IMG G17_024973_0341_MU_00N239W.IMG D19_034703_0657_MA_00N199W.IMG D19_034703_0657_MU_00N199W.IMG F02_036477_1277_MA_00N030W.IMG F02_036477_1277_MU_00N030W.IMG F02_036477_1278_MA_00N223W.IMG F04_037334_1613_MA_00N028W.IMG F04_037334_1613_MU_00N028W.IMG In April 2019, the PDS Imaging Node sent us a new cumindex.tab with changes to reflect their moving of the improved MARCI EDRs from these volumes to their original volumes, replacing the original EDRs and index.tab information. Volumes in the range above now contain only the never-before-archived images. In that process, some whitespace in some RATIONALE_DESC was removed from the index.tab and cumindex.tab, so it no longer matches the RATIONALE_DESC in the EDR header; for example, B22_018361_1102_MA_00N276W is 'global map swath (dark calibration)' in the EDR header but 'global map swath (dark calibration)' in the tab files. This applies to many 'dark' and 'nightside' EDRs, not just those that were originally on these volumes. MROM_0638 and MROM_0639: Images D21_035406_0897_MA_00N312W.IMG, D21_035407_0897_MA_00N339W.IMG, D21_035448_0911_MA_00N019W.IMG, D21_035449_0911_MA_00N046W.IMG, and D21_035450_0912_MA_00N073W.IMG were affected by what was likely a single-event upset. MARCI was commanded to reboot at 02/20/2014 00:41:24 SCET UT. MROM_0619: Beginning with orbit 34581, images were affected by what was likely a single-event upset. Additionally, images in the orbit range 34585-34603 were affected by an SSR read failure at 12/12/2013 09:27:25 SCET UT. MARCI was power-cycled on 12/13/2013 (off at 20:51 SCET, on at 22:55) to reset the hard partition back to empty. MROM_0613: Images in the orbit range 34200-34219 were affected by what was likely a single-event upset. MARCI was commanded to reboot at 11/13/2013 22:04:40 SCET UT. MROM_0367: Images G02_019003_1337_MA_00N330W.IMG and G02_019004_1337_MA_00N358W.IMG were affected by what was likely a single-event upset in the MARCI DSP code. MARCI was commanded to reboot at 8/16/2010 20:00:00 SCET UT in order to reload the code. MROM_0317 through MROM_0325: Images B19_016884_0593_MA_00N078W.IMG through B19_017190_0697_MA_00N152W.IMG were affected by what was likely a single-event upset in the MARCI DSP changing a value in the companding table; pixels with dn=203 are scattered throughout those images. MARCI was commanded to reboot at 3/27/2010 23:53:44 SCET UT in order to reload the companding table. MROM_0226: Images B03_010688_1533_MA_00N121W.IMG through B03_010721_1546_MA_00N302W.IMG were affected by what was likely a single-event upset in the MARCI DSP changing a value in the companding table; bright (dn=174) pixels are scattered throughout those images. MARCI was commanded to reboot at 11/8/2008 22:17:17 SCET UT in order to reload the companding table. MROM_0076: MARCI was powered off at approximately 13:52 on 2007-07-20, during acquisition of frame 985 of image 4A_05_101480FA00 (P09_004596_2801_MA_00N107W.IMG and P09_004596_2801_MU_00N107W.IMG). Data from frame 984 are repeated in frames 985-1322 of those two IMGs. MROM_0001: The images acquired in mission phase CRUISE are not of Mars and were not acquired from orbit (MRO had not yet arrived at Mars), so some of the values (e.g., orbit number, solar distance) in the index.tab file are not meaningful. General: Some MARCI product names have a latitude and longitude specification other than the '00N'BBB'W' described in the MARCI EDR SIS. For these images, the sub-spacecraft (for off-planet images) or center (for images of Mars) latitude and longitude were used in the name either because it was not possible to calculate an equator-crossing longitude or because such a calculation would have resulted in duplicate product names. For example, images on the stray light calibration orbit 1762 (volume MROM_0013) are named with '27S134W', '58N146W', and '71N317W'. The MARCI planning periods are represented in image product filenames by the mission phase descriptor, as noted in the MARCI SIS. The planning periods are: CRU Cruise instrument check-out/calibration (August 2005) MOI post-Mars Orbit Insertion instrument check-out (March 2006) T0n Transition to Primary Mission (September-November 2006) Pnn Primary Mission (November 2006 - August 2008) Bnn Primary and Extended Mission (September 2008 to June 2010) Gnn Extended Mission (July 2010 to present) where n is a digit from 0 to 9. MRO's Extended Mission starts on 20 December 2008 and ends on 31 December 2010. MARCI planning periods for Primary Mission and beyond, however, are defined by Mars year and Earth month; the letter represents Mars year, and the number represents Earth month within that Mars year. The planning period naming scheme was developed to be consistent with that of the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) dataset to simplify comparisons of data across several Mars years. The solar longitude ('L sub s') range of a given numbered Earth month is roughly the same across the two datasets; for example, MGS MOC periods M12, E12, R12, and S12 correspond to MRO MARCI periods P12 and B12. The letter B represents beta, the second Mars year of MARCI imaging; G represents gamma, the third year.
