Do anyone knows final orbital elements?

QUOTE (dilo @ Jul 25 2005, 10:00 PM) Answering by myself.. ..some informations here: http://sci.esa.int/science-e/www/object/in...fobjectid=36683 It seems that Smart will make an equator/North emisphere high-res coverage... You will find also many other informations, moon eclipse images and a familiar stuff on page 27 of second pdf document ( !)... -------------------- I always think before posting! - Marco -

Are there Smart-1 moon images elsewhere besides SMART-1 official images? I count only 7 images of the moon. What's up with that?

Well...it's a bit of a stretch to call pushbroom imaging a "new" imaging technique. It's a pretty old technique, even in space -- Mars Global Surveyor has been doing it for many years, and more recently so has Odyssey, and even another ESA spacecraft, Mars Express, right?

It's a pretty old technique, even in space -- Mars Global Surveyor has been doing it for many years, and more recently so has Odyssey, and even another ESA spacecraft, Mars Express, right? Technically, what they are using is what we call "pushframe" imaging -- they have an area sensor with regions of different colors, and they take an image roughly every band height's advance over the surface. Pushbroom imaging uses a single line array; this is what is used by MOC and MEx. I won't claim to have been the first person to have ever thought of this, but I independently developed it for an unselected Discovery proposal in 1994, and we first used it in a flight instrument for the MARCI on MCO. THEMIS is the first time it was used in Mars orbit, and the MRO MARCI also uses it, as will the Wide Angle Camera on LRO. Typical ESA press release. -------------------- Disclaimer: This post is based on public information only. Any opinions are my own.

Emily said (quite correctly):
"Well...it's a bit of a stretch to call pushbroom imaging a "new" imaging technique. " True - but they did add "never used before in lunar orbit" or words to that effect. Which I presume is true. Phil -------------------- ... because the Solar System ain't gonna map itself.

Preliminary impact data including a site - on the far side, but they say it might be changed so they can monitor it.
Phil Perilune of 0 km * Date = 2006/08/17 ~11:00 (uncertainty ~ 1 day) * Radius of perilune = 1738 km * Radius of apolune = 5096 km * Inclination = 91.4° * Right ascension of ascending node = 239.7° * Argument of perilune = 217.5° * Sun-moon-perilune angle = 87.0° * Earth-moon-perilune angle = 134.4° * Longitude of perilune = 174.4° * Latitude of perilune = -37.5° * +X to Earth angle when +Z to velocity at perilune = 105.0° * Velocity at perilune = 2.051 km/s * Perilune radius change per orbit -1.888 km/rev It should be noted that the impact date of 17 August 2006 assumes no further changes are made to the spacecraft orbit. It is possible that this date will change to accomodate specific requests to enable monitoring of the impact from Earth. -------------------- ... because the Solar System ain't gonna map itself.

I, too, thought that the ESA Press Release was a classic bit of ESA-Speak, but as Phil points out it was - strictly - true. Well, apart from the 'push-frame' vs 'push-broom' question, anyway! I wonder when, if SMART-1 reaches a perilune of 0km in mid 2006, ESA will actually announce EOM? 2007? Perhaps they'll claim a new record for *surface* push-broom operations... ...it's said to be quite dusty down there!
On a less silly note, I'm intrigued by the commencement of this new imaging mode at what is by any standards a late stage of the mission. Reading the ESA PR, it looks to me like push-broom/frame is actually quite hard on the imaging system - am I right in this?

Update to the SMART-1 end of mision post: the longitude is ambiguous, but I checked with the phase angle data and it must be 174.4 degrees east, not west.

SMART-1 approach to lunar polar orbit, November 2004
http://www.svengrahn.pp.se/histind/smart/smartatmoon.html -------------------- "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 |

Another new image...
http://www.esa.int/SPECIALS/SMART-1/index.html They are being released at a breathtaking pace these days - assuming you breathe cautiously. I actually emailed Josset at Space-X to point out that people thought SMART-1 was doing nothing because there were no releases. No reply. But we are getting pictures more frequently.

Phil Phil: Breathing cautiously? Breathing bi-monthly, maybe... ...it all leads my cynical little mind to wonder if it's because the rest of the images are simply too poor quality-wise for ESA to admit to!
