Z = GMT / UT, P = Pacific
Future, Unconfirmed, Confirmed

NASA TV coverage starts at 2030Z / 1230P

TCM5 was not required.
2049Z / 1249P - Tank Pressurize - nominal pressure reported (@2053Z)
2103Z / 1303P - Switch to LGA ( 2 way doppler @ 2104Z, Lock at 160bps :2105Z)
2107Z / 1307P - Turn to Burn attitude (start of turn confirmed via doppler & telem @2110Z - Slew finished @2119Z via ACS)
2124Z / 1324P - Start of MOI Burn (confirmed via Doppler @2123Z )
(tank pressure about 3psi below predicts but within margins @2131Z )
(307m/sec accumulated delta @2135Z)
(401m/sec accumulated delta @2139Z)
(588m/sec accumualted delta @2144Z)
(telem. indicated eclipse entry @2146Z)

- actual time 21:46:23Z)
2151Z / 1351P - Nominal End of Burn
2216Z / 1416P - Nominal AOS - (signal aquired - 1 way doppler @2116Z - 22:16:08 actual time)
(2 way doppler @2223Z)
2230Z / 1430p - 1641m/s burn indicated by telementry.

MRO is now orbiting the planet Mars biggrin.gif

Status check at 2245Z

Flight Software - Burn done at 20% Utilisation
Prop Nominal
ACS, Earth point on reaction wheels, Star tracker aquisition ( 8 stars ), Burn time 1641 seconds vs 1606 expected. 1000.48 m/s compared to 1000.36m/s expected.
Thermal - all temps nominal. A few alarms due to soak back from the rcs thrusters.
EPS - Nomincal, trickle charging batts ( 110% state of charge ) - 870 Watts being used, 1650 Watts available from arrays.
Telecom - Nominal, on primary equipment, uplink and downlink signals as expected, already got a command in.
Fault Prot - Quicklook, no abnormal responses to the burn, out of go-fast mode.
Nominal termination to the MOI nominal block.

11th March 0030 Press Conf Update

Usual superlatives from senior management that don't tell us anything.

Jim Graff acknowledged help from NOAA w.r.t. Solar Weather, and the DSN's outstanding job.
Howard Eisan : MRO is safe, stable, on earth point, transmitting at 550kbps. We've earned the 'RO' of MRO. Dippled less than 10% into the batteries, commanded velocity change 2237.6 mph, overshot by 0.4mph, during the burn we underperformed by 2%, burned by 33 seconds longer to make up the difference. First hr of Nav data - orbit 35.5 hrs (predict 35.6) 264 x 28,000 mile orbit.
Rich Zurek : 2 of our 8 investigations were ones lost with MCO, one of those was also lost with Mars Observer. This completes replacement of all the Mars Observer instrumentation. We're going to knock your socks off - it's a good day.

Sally from TPS : Break for 2 weeks, what are you going to be doing (are you going to be celebrating for two weeks) - JG - stand down for w'end for a rest. Then prepare for aerobraking. ORT for Aerobraking, reconfig spacecraft for aerobraking, and some software patches to send up (9 uploaded to date, a few more to go). One other thing - we will take some early images - engineering images not science quality, make sure they work properly, processing that data on the ground to make sure the processing centres can extract the images from the data.

Sally asked when that science will start. RZ mentioned the use of aerobraking (lowest altitude is 60 miles) to understand structure of atmosphere. Sally asked if aerobraking is hard every orbit. RZ said that most of the closest approaches will be over the south pole. They dont expect big dust storms.

That's all the questions- again, kudos to Sally for asking them something. Unarguably the most important moment in Mars exploration since MER landing and potentially more important than anything between then and MSL landing scientifically, and in terms of infrastructure on orbit - $700M's worth of project - and that's three conferences where Sally was almost the only person to ask any questions. Either JPL PAO has furning the media with every single piece of information they could want before the event, or the media seem to be barely taking note of the mission because it's not as sexy as a landing ( there were plenty of spare seats in the V.K. auditorium, at Spirit's landing conf, you couldnt swing a cat in there ). Under-representation of mission rant over.
