By a happy coincidence your simulation date of 15 March is my birthday. I'll take this as a birthday card! Happy Birthday, Phil But remember what the soothsayer said to Caesar: "Beware the Ides of March." Julius Caesar (Act I, Scene II). |

Well, Alex, I bewore the Ides of March as instructed... but nothing happened.

I guess you didn't get the present labeled: "To Phil from you old pals Brutus and Cassius." Alex: Phil, liking British comedy as he does, probably took the Kenneth Williams option: 'Infamy! Infamy! They've all got it infamy!' Ooh, er, Matron! Bob Shaw -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

Actually Frankie Howerd is the person I think of in connection with such classical goings-on. My apologies to all the non-brits out there whose upbringing didn't include frequent exposure to the cream of British culture. It is - uh - cream that floats to the top, isn't it?

"test images to be taken week of March 20"
Are they just going to snap few images of anywhere on Mars or is there some specific target for those test images... If they asked me I would take image of Opportunity’s way to Victoria...that could help a bit in navigating through those dunes... Does anybody knows more? -------------------- The scientist does not study nature because it is useful; he studies it because he delights in it, and he delights in it because it is beautiful.

You don't just "snap anywhere" with a multi million $ camera..................

You don't just "snap anywhere" with a multi million $ camera.................. True, but the uncertainties in MOI burn performance can lead to large differences in what part of Mars will be under you during, say, 10th periapsis passage. This limits and possibly prevents any extensive planning before MOI on what targets you'll get to see. So in a sense, they might just be "snapping anywhere", pointing nadir and catching whatever is below. It's an engineering test anyway, not scientific observation. Once they get into their science orbit they'll have much more accurate ephemeris and be able to actually target their observations. -------------------- |

It's going to be March 23! Images will be taken during 2 orbits. The camera will take pictures of the middle latitudes of the southern hemisphere. (From space.com)

They'll be unveiled at HiROC in a special event if you look at the hiroc website.

I hope they'll get some shots of those canals I keep hearing everyone
talk about. Maybe even some of those ancient Martian cities along the planet's equator made of solid crystal, or even the giant cannon they used to launch that Earth invasion back in 1897 - and 1953 - and 1988 - and 2005. -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

Interestingly enough, per the latest SPICE prediction kernel MRO won't have a periapsis passage on March 23rd UTC. There will be a periapsis around ~5:00am UTC on the 24th, which would be the 23rd Mountain Time at least.
MRO will be over the night side at periapsis so I guess the HiRISE images will be taken some time before, at higher altitudes? Here's the nadir track showing MRO as a red dot at 04:50am March 24th UTC, just going into the night side: Altitude at that point is about 1500km. Altitude when MRO is over the Valles Marineris region is about 4000km at 04:30. -------------------- |

Is that the prediction based on actual orbit elements reconstructed after MOI or an a priori best-guess value? Since it came out on March 20th I would think the former. Here's a bit of the lbl file: QUOTE MISSION_NAME = "MARS_RECONNAISSANCE_ORBITER" SPACECRAFT_NAME = "MARS_RECONNAISSANCE_ORBITER" DATA_SET_ID = "SPICE_SPK_FILE" KERNEL_TYPE_ID = "SPK" PRODUCT_ID = "spk_ab_ref060320_060312_060914_p-v1.xsp" PRODUCT_CREATION_TIME = 2006-03-20T08:47:06 PRODUCER_ID = "MRO_NAV_TEAM" MISSION_PHASE_NAME = "CRUISE" PRODUCT_VERSION_TYPE = "SPK-SFDU" PLATFORM_OR_MOUNTING_NAME = "N/A" START_TIME = 2006-03-12T09:38:55 STOP_TIME = 2006-09-14T04:25:19 Obviously most of file is based on prediction, since it covers the entire aerobraking phase out to September 14. -------------------- |
