Err... anyone know of any good image deconvolution software?

Egads. Merry Christmas from EPOCh! Thanks for the heads up, Gordan. I think I'll sit this one out and watch you wizards try to make something better of these data smile.gif

Now if I could only remember why I was asking that question in the first place...

23 frames from March 18, 2008, covering over 5.5 hours, again motion-interpolated in an AVI file (1 meg). I believe there's material for a complete rotation as it goes on to March 19 so this is still a work in progress.

Ooh, neat! More, higher resolution movies of Earth! Can't wait for it to hit PDS in about a couple of years from now! rolleyes.gif

Interesting that they are implying it may be possible to see sun glints on extrasolar planets.

PDS RELEASES EPOXI (EPOCh) MISSION DATA

The NASA Planetary Data System is pleased to announce release of the data from EPOXI, Extrasolar Planet Observation and Characterization (EPOCh) stage of the mission. The delivery includes raw and calibrated images (exoplanet transits and Earth) and infrared spectra (Earth) acquired during 2008.
The data are available through the PDS Small Bodies Node. To see and download the data as well as mission and instruments information, go to:

After more than six months, the EPOXI mission site has some new updates. Nothing particularly interesting anyway
QUOTE
As the EPOCh team moves from processing data to writing papers about their results, the DIXI team is ramping up its activities in preparation for the encounter with comet Hartley 2 on November 4.

The majority of the data from EPOCh have been made public both at the Small Bodies Node of NASA’s Planetary Data System (PDS-SBN) and at the Multi-Mission Archive at Space Telescope (MAST). A few datasets taken in 2009 and some derived data (such as the final light curves of transiting planets) still remain to be delivered.

There were two significant activities for DIXI in February. On February 16 we carried out the first of several cruise calibrations that are planned. The others will be in the summer, a few weeks prior to encounter, and a few weeks after encounter. These data ensure that we understand the operation of the instruments and can readily provide calibrated data after the encounter. The second significant activity in February was a face-to-face meeting of the science team with key members of the operations team to lay out the detailed sequence of observations to be made during the encounter (much like the Sequence Symphony from Deep Impact). These observations will include observations on approach starting 60 days prior to closest approach and observations on departure for 21 days. The details of these plans must be decided well in advance because it is necessary to test them extensively on simulators in order to be sure that everything operates as planned. Deep space flyby encounters such as this one do not allow any opportunity to redo any observations if something goes wrong and last minute changes are very risky. Thus these encounters are dealt with much more rigorously than are observations, e.g., with telescopes in orbit around Earth. For those observatories, it is essential to ensure the safety of the spacecraft and instruments but if the observation fails it can be repeated. We have no chance to repeat the observations. We will continue to change some details to the observing sequence over the next few months but the basic approach is completely determined at this time.

According to the two Facebook profiles related to the mission (EPOXI Mission and Deep Impact Flyby), AutoNav on the flyby probe, unused for years, is being checked next Tuesday.

EPOXI is now 3.5 days from its final(?) Earth flyby. It's already closer to Earth than Herschel and Planck!

There was an interesting paper on Hartley 2 this week on ArXiv.
In particular, it is predicted that H2's surface will not be too different from comets already visited by spacecraft. It seems to be loosing a significant percentage of its radius at each perihelion, and could be extinct in just a century.
The author also calls for a mission to a really old comet like Wilson-Harrington or a relatively old one like Encke. He predicts that they "will have a more extreme surface morphology, than the cometary surfaces that have been imaged up to now"

Salutations UMSF members,

We just completed a point-spread function calibration of the HRI this morning in preparation for Encounter. We also uplinked and activated the sequences to take the first 20-days of approach images from E-60days to E-40days. The first images should clock out around 13:30 UTC Sunday 9/5 with the images hitting the ground at 14:23 UTC. There's talk of putting a few of these on the website, but 60-days out, it should be just a fuzzy blob a few pixels across.

Keep refreshing epoxi.umd.edu or the EPOXI facebook page for updates!
