Does anyone know what the field of view of the Narrow Angle and the Wide Angle Camera is?

From http://www.lpi.usra.edu/meetings/lpsc2007/pdf/1305.pdf:
QUOTE
The Mercury Dual Imaging System (MDIS) consists of wide-angle and narrow-angle imagers mounted on a pivot platform that enables the instrument to point in a different direction from the spacecraft boresight. The MDIS narrowangle camera (NAC) is monochromatic with a 1.5° field of view, while the wide-angle camera (WAC) has a 10.5° field of view and a set of 11 color filters (plus one broad-band filter) ranging from 415 nm to 1020 nm.
They both have 1024 by 1024 CCDs.

Based on Emily's data, this is how Messenger sees Mercury right now:

Can someone here please point me to updating orbital elements (TLE format) for MESSENGER's trajectory? Am I right that there is still no master repository of deep space heliocentric orbital elements? For that matter, such an archive should include fragments before and after various historical gravitational assists. Anything like that around? Thanks

Does JPL's HORIZONS system give you what you're looking for?

Update [12/26]: Confirmed that no data will be on ground until 16th. Big data crunch 16-18, followed by press conference/release. Then plenty of people in Laurel MD for a couple of weeks of photo-geology.


Yeah, LPSC will probably the first real presentation of the results. Of course, abstracts are due next week, so they'll all be placeholders...

Yes. I didn't realize that HORIZONS has spacecraft. Thank you. Now just need to convert these into TLE format.

Some new visualizations are up on the MESSENGER page for this flyby.

Are you referring to the fantastic work done under the visualization tool? Astounding...magnificent outreach... biggrin.gif

MESSENGER Only One Week from Mercury

One week to go and fortunately no big surprises. Also, the mid-December trajectory correction maneuver (TCM-19) went so well that the scheduled January 10 maneuver will not be necessary. Data gathering should begin in two days. Very exciting times.


EDIT: I just noticed that on January 30 (1 p.m. EST.), there is a "NASA Space Science Update on the Mercury flyby" at NASA Headquarters. Is this the main science press release?

Any chance they'll show something on NASA.TV ?

MESSENGER Mission News
January 8, 2008
Six Days from Mercury and Counting!

Rapid fire! Another update from MESSENGER team. Mission operators have sent commands to acquire nine sets of optical navigation images at Mercury. APL and the Planetary Society are also hosting a public reception on the evening of the encounter. The reception will include a talk by Robert G. Strom, a professor emeritus at The University of Arizona who was involved in Mariner 10 and is now a member of the MESSENGER Science Team. He'll "share his unique perspective on the significance of the MESSENGER mission." This might be of interest to those of you in the DC-area.

While we wait for new images to start coming in, I thought I'd do a bit of Googling for existing images... these 3D views are pretty interesting...
