STS-93 (Columbia)
1999-040A
After a launch delay, OV-102 was towed to the VAB to make room for OV-104 in the OPF.
Launch mass was 122534 kg. Landing mass is 99781 kg. Payload chargeable mass is 22753 kg.
Chandra launch mass 5865 kg. dry 4790 kg. IUS SRM-1 10064 kg full, 1164 kg. dry IUS SRM-2 3800 kg full, ASE 2434 kg. Other support 583.
CXO 5865 IUS 13871 ASE 2434 SE 583
Tot 22753 kg
5563 (CSC data); 5677 (to make the SODB deploy mass come out right).
Fuel cell pH signal by Collins; AC bus short very briefly. Lost one controller on center engine and one on right engine. There are 3 AC bus, each supports 2 controllers, each engine has 2 controllers, never from the same AC bus. If you lose both controllers,abort options need to be assessed. But we only lost one controller per engine, so there was no problem. Then, MECO came a second early with a 15 foot per second underburn due to being 4000 lb of LOX short. After launch it was discovered a loose pin repairing a cooling tube on an SSME broke loose, and three tubes ruptured causing a hydrogen leak during ascent. The controller spotted the low pressure in the combustion chamber and added more LOX to the mix.
The switch to the backup controller actually reduced the sensitivity of the fuel leak; it set a different bias value on the SSME engine pressure, which actually caused less of an underspeed than would have been the case.

MER-1 (Opportunity)
2003-032A
MER-1 is "Opportunity".
MER-B Launch 2003 Jul 8 , landing 2004 Feb 25.
The pre-TCM1 miss distance is 340000 km, which is probably the flyby distance of the final stage.
B.R B.T = (204197,274289) with TCA 2004 Jan 26 1623:22.
Landing at around 2S, 354E. The landing site was named Challenger Memorial Station.
Landing site is 1.9462S 354.4734E. AIAA2004-4980 quotes actual as 1.94828S 354.47417E. Diff is (0.002,0.001) deg. Radius of Mars is 3397 km, so 0.001 deg corresponds to 17 murad or 60 meters. Hence 1 km = 0.01687 deg.
MER-1 entry mass was 832 kg, 5 kg more than Spirit.
At Gusev, b=14.57 so in X, 1 km = 0.01743 deg.

A Sol is 24 hours 39 minutes 35.244 seconds
Spirit: (Sol 1 ends 2004-01-04 14:15 UTC) - = landing + 09:49 Spirit landed at 14:34 LST-A = 0426 UTC Jan 4. So 24:39 LST-A is 0426 + 10:05 = 1431 UTC Jan 4. 1415 UTC = 1434+0949 LST-A = 24:23 LST-A = EOLST - 13m. Wassup? ERT error? LT= 9min
If Sol 1 end = 14:15 ERT = 14:06 UTC, that's 24:14 LST-A.
LST-B = LST-A + 12:01:10 Oppo landed at 13:33 LST-B. 0454 UTC. Oppo: (Sol 1 ends at 2004-01-25 15:48 UTC) = 10:54 after landing = 24:27 LST-A = EOLST - 12min. LT = 11 min.
If Sol 1 end is 15:48 ERT = 1537 UTC then end is 24:16 LST-A.
Ahhh.. LST runs on a 24-hour martian day with 1 mars day = 88775.244 SI second = 86400 Mars seconds so 1 Mars second = 1.0275 Earth seconds. Thus, 9:49 Earth = 9:33 Mars and A Sol 1 ends at 14:34 + 9:33 = 24:07 ? 10:54 Earth = 10:36 Mars and B Sol 1 ends at 13:33 + 10:36 = 24:09 ? Suspect ERT. Conclude A Sol 2 starts at 1406 UTC 2004 Jan 4 and B Sol 2 starts at 1537 UTC 2004 Jan 25.
Nominal landing is at 0435 ERT and 0505 ERT (A,B).= 0426 and 0454 UTC.
JD = ( A Sol - 2 ) * 1.02749125 + 2453009.087500 = ( B Sol - 2 ) * 1.02749125 + 2453030.150694
A Sol = 2 + ( JD - 2453009.087500 ) * 0.9732443 B Sol = 2 + ( JD - 2453030.150694 ) * 0.9732443
