OK in order to kick of the Hubble thread I'd thought I would post this news about a Hubble documentary being released. Hubble's 15th Year anniversary falls on the 25th of April 2005. In honour of the telescope a full length DVD movie about the story of Hubble using Hubble imagery has been produced.
The 23 April edition of NewScientist is giving away 40000 DVDs of Hubble: 15 Years of Discovery. For a fix of wow from Hubble check out the Hubble Heritage Gallery. |

Just got my copy of the DVD from New Scientist, and was a bit annoyed.
It didn't come with a case! I wanted a nice case that I could put with my other DVD's. All I got was a plastic envelope for it.  Haven't watched it all yet but it seems okay so far. jG -------------------- Turn the middle side topwise....TOPWISE!!

The Hubble DVD was certainly worth what I paid for it, but suffers from a certain blandness - Horizon/Nova do such things with much more humanity!
Me, I'm waiting for Burt Rutan to offer a re-boost to geosynchronous orbit (with 'observer' seats available) on the combo SpaceShipThree/Nautilus stack! Ah, if only... -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

Hubble has caught a fantastic image of the Fomalhaut dust ring...

SERVICING HUBBLE: SHUTTLE PLANS REFINED
--------------------------------------- Preparations for a shuttle mission to upgrade and repair the Hubble Space Telescope in late 2007 or early 2008 are picking up steam as engineers map out the details of a five-spacewalk flight designed to keep the venerable observatory alive and well through at least 2013. http://spaceflightnow.com/news/n0512/05hubbleservicing/ AN INTERVIEW WITH NASA ADMINISTRATOR MIKE GRIFFIN ------------------------------------------------- In a wide-ranging interview with CBS Space Consultant William Harwood, NASA Administrator Michael Griffin - he insists on being called Mike - reiterated his strong support for a shuttle mission to service the Hubble Space Telescope. http://spaceflightnow.com/news/n0512/05griffin/ -------------------- "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 |

Good for Mike Griffin. As far as I can see, a Hubble servicing mission is one of the only manned missions on the radar that can be justified on the basis of scientific return. Hubble has proven itself time and again as a versatile workhorse of astronomy and astrophysics, with capabilities no other observatory can match.
Does anyone know if they've figured out how to retrofit the gyros that Hubble keeps wearing out to be more durable? If it weren't for those regularly wearing out, Hubble might last a lot of years before something important randomly fails. |

Griffin Vows To Send Shuttle Mission To Hubble
by Staff Writers Washington DC (SPX) Jan 10, 2006 NASA administrator Michael Griffin repeated a pledge Tuesday he has made several times since taking over the space agency last April. Speaking to a packed house at the 207 th meeting of the American Astronomical Society, Griffin said because of his deep appreciation of the scientific importance of the Hubble Space Telescope, "NASA will, if at all possible, use one of the remaining flights of the space shuttle for Hubble servicing." http://www.spacedaily.com/news/Griffin_Vow..._To_Hubble.html -------------------- "After having some business dealings with men, I am occasionally chagrined,

Review: Chasing Hubble's Shadows
--- For decades astronomers have been peering farther back into the universe, trying to understand how stars and galaxies formed. Jeff Foust reviews a new book that offers an update on what astronomers have found and the questions they have yet to answer. http://www.thespacereview.com/article/537/1 -------------------- "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.

Assessment of Options for Extending the Life of the Hubble Space Telescope: Final Report 2005
http://books.nap.edu/catalog/11169.html The Hubble Space Telescope (HST) has operated continuously since 1990. During that time, four space shuttle-based service missions were launched, three of which added major observational capabilities. A fifth SM-4 was intended to replace key telescope systems and install two new instruments. The loss of the space shuttle Columbia, however, resulted in a decision by NASA not to pursue the SM-4 mission leading to a likely end of Hubble s useful life in 2007-2008. This situation resulted in an unprecedented outcry from scientists and the public. As a result, NASA began to explore and develop a robotic servicing mission; and Congress directed NASA to request a study from the National Research Council (NRC) of the robotic and shuttle servicing options for extending the life of Hubble. This report presents an assessment of those two options. It provides an examination of the contributions made by Hubble and those likely as the result of a servicing mission, and a comparative analysis of the potential risk of the two options for servicing Hubble. The study concludes that the Shuttle option would be the most effective one for prolonging Hubble s productive life. -------------------- "After having some business dealings with men, I am occasionally chagrined,

Astrophysics, abstract
astro-ph/0604394 From: Roelof S. de Jong [view email] Date: Wed, 19 Apr 2006 02:56:56 GMT (701kb) NICMOS Status Authors: Roelof S. de Jong, Santiago Arribas, Elizabeth Barker, Louis E. Bergeron, Ralph C. Bohlin, Daniela Calzetti, Ilana Dashevsky, Mark Dickinson, Anton M. Koekemoer, Sangeeta Malhotra, Bahram Mobasher, Keith S. Noll, Adam G. Riess, Alfred B. Schultz, Megan L. Sosey, Thomas Wheeler, Tommy Wiklind, Chun Xu Comments: 12 pages, 10 figures. More information on the newly discovered NICMOS count-rate dependent non-linearity and how to correct for it can be found at this http URL: http://www.stsci.edu/hst/nicmos/performanc...nlinearity.html Journal-ref: Conference proceedings of The 2005 HST Calibration Workshop, eds. A. Koekemoer, P. Goudfrooij, L. Dressel, p. 121 We provide an overview of the most important calibration aspects of the NICMOS instrument on board of HST. We describe the performance of the instrument after the installation of the NICMOS Cooling System, and show that the behavior of the instrument has become very stable and predictable. We detail the improvements made to the NICMOS pipeline and outline plans for future developments. The derivation of the absolute photometric zero-point calibration is described in detail. Finally, we describe and quantify a newly discovered count-rate dependent non-linearity in the NICMOS cameras. This new non-linearity is distinctly different from the total count dependent non-linearity that is well known for near-infrared detectors. We show that the non-linearity has a power law behavior, with pixels with high system, or vice versa, pixels with low count rate detecting slightly less than expected. The effect has a wavelength dependence with observations at the shortest wavelengths being the most affected (~0.05-0.1 mag per dex flux change at ~1 micron, 0.03 mag per dex at 1.6 micron). http://arxiv.org/abs/astro-ph/0604394 -------------------- "After having some business dealings with men, I am occasionally chagrined,
