Looks like the Deep Impact list has been revived. Posting here for others to get back on board:
********************************************************************** EPOXI E-News #1 May 2008 ********************************************************************** WELCOME BACK! Did you know that the Deep Impact Flyby Spacecraft has a new assignment? The EPOXI mission combines two exciting science investigations in an entirely new mission that re-uses the Deep Impact spacecraft. The Extrasolar Planet Observation and Characterization (EPOCh) investigation will observe stars that have known transiting giant planets. The Deep Impact Extended Investigation (DIXI) of comets observes comet 103P/Hartley 2 during a close flyby in October 2010. The education and public outreach team decided to get back in touch with our Deep Impact friends and begin sending out newsletters again to keep you informed of these two exciting investigations! During the two years since our last newsletter for Deep Impact, the science team has stayed busy continuing to do more analysis on the data collected in July 2005. The science team also proposed and was awarded an extended mission teaming up with a group from Goddard Space Flight Center. EPOXI website: http://epoxi.umd.edu/ Mission Overview: http://epoxi.umd.edu/1mission/index.shtml Press Releases: http://epoxi.umd.edu/7press/index.shtml DI Results: http://deepimpact.umd.edu/results/ ********************************************************************** MISSION STATUS Dr. Deming, Principal Investigator (PI) for the EPOCh portion of the mission, sends us the latest mission status report in which he tells us about the current observing target GJ436. “This is an exciting time for EPOCh, as we search for an exo-Earth orbiting a stellar neighbor of our Sun!” reports Dr Deming. He also talks about the plans to observe a very special planet in late May and early June. Read his status report as well as past reports from other team members at http://epoxi.umd.edu/1mission/status.shtml ********************************************************************** EPOCh TARGETS The EPOCh component of the EPOXI mission will carefully study a small number of stars in order to learn more about planets that we know are orbiting those stars by watching the planets as they transit (cross in front of) the star. EPOCh will also search for clues to other planets that might be orbiting the same stars. Read more about the EPOCh science targets to find out which stars are being observed. http://epoxi.umd.edu/2science/targets.shtml ********************************************************************** PLANET QUEST Are we alone? For centuries, human beings have pondered this question. Medieval scholars speculated that other worlds must exist and that some would harbor other forms of life. In our time, advances in science and technology have brought us to the threshold of finding an answer to this timeless question. The recent discovery of numerous planets around stars other than the sun confirms that our solar system is not unique. Indeed, these "exoplanets" appear to be common in our galactic neighborhood. The EPOCh investigation is part of a larger family of missions studying extrasolar planets. Learn more at the Jet Propulsion Lab Planet Quest Web site. http://planetquest.jpl.nasa.gov/index.cfm ********************************************************************** OBSERVING CHALLENGE The transits that will be studied for EPOCh are extremely difficult to observe because the change in brightness is very small and requires high precision photometry that can be accomplished with instruments on the Deep Impact spacecraft. Observers on Earth can still take a look at the stars in the night time sky. The selected stars are also pretty dim because we don’t want them to saturate or over expose the spacecraft instruments but they are bright enough to be visible in amateur telescopes if the sky conditions are good and the skies are dark. Like people, stars have multiple identifiers. EPOCh’s first target was a star labeled as HAT-P-4 by the scientists observing it. They made their own list of target stars so that was their shorthand name. But HAT-P-4 has numerous other names which are more useful in identifying it in other databases. HAT-P-4 = SAO 64638 = TYC 2569-1599-1 is a magnitude 11, G-class star located in the constellation Boötes.

As a member of the EPOXI flight team, I am astonished that this data has been made public yet. The EPOCh portion of EPOXI finished 8/31/08 (photometry of transiting hot-jupiters and observing Earth as an exo-planet analog). The science team has had over 7 months to analyze the data and the only thing made public is the lunar transit animation. Granted, that's pretty sweet, but you'd think they would release some more data.
I met Doug (UMSF founder) on Tuesday (3/17) when he was here at JPL. I'm impressed with what you all are doing on the site with MER data, among the other missions. I'd love to see UMSF participate real-time with the Hartley-2 flyby similar to the DI prime mission flyby of Tempel-1. Let me talk with our Public Outreach people and our science team and I'll see if I can get any data released to the "world". What exactly would you guys want? .jpgs? raw binary images? Please let me know and I'll see if I can get any data released. Many thanks and keep up the great work! I always like to see people excited about EPOXI when most people at JPL don't even know we exist! ~Rich p.s. we just published a paper on how we did the EPOCh observations at the 2009 IEEE Aerospace Conference. I'm not sure if the paper is available to the public free-of-charge, but I'll see if I can get a copy of the paper and presentation out... |

Please let me know and I'll see if I can get any data released. I myself prefer PDS formatted data and there are probably lots of people here that also prefer it but PNGs are better known and are probably the best option to make the data easier to use for lots of people. As previously discussed, PNGs are far better than JPGs due to the absence of compression artifacts and the fact that they can be 16 bits/pixel when needed. Their only drawback compared to JPGs is bigger files. |

You'll have to stay perched on the edge of your computer chair until then. I'll see if I can get anything released to the world, but you may have to settle for .jpgs. Sorry! .jpgs are better than nothing! ~Rich |
