Seeing that launch is coming up and no topic exists yet for this one, here's one. So does anyone have ideas of what AFSPC-11 is? I was initially surprised by the use of the -551, but according to Gunther the EAGLE spacecraft will be on board and to be flown directly to geostationary orbit. That spacecraft "...can support payloads up to a weight of 1086 kg for a mission of at least one year." so it could be weighting up to 2 tonnes, which is already about half of the maximum capability of the -551 (just shy of 4 tonnes to GEO).So another "satellite surveillance/inspector" thingy? What other kinds of satellites would the AFSPC potentially operate?

It has a humorous logo. Took me a while to get it. Younger people might not right away. (Sorry, can't post it yet)

ISAL (Inverse Synthetic Aperture Ladar) to provide high resolution images which are not limited in resolution by the diffraction limit of the telescope collecting the imaging data. This makes it an ideal method for imaging Geosynchronous Earth Orbit (GEO) space objects which happens to be ISAL's primary mission.

Is this the launch that at one stage people thought initially was an X-37B flight?
Inverse synthetic aperture LADAR for geosynchronous space objects – signal-to-noise analysisPellizzari, Matson, and GudimetlaSeptember 2011http://www.dtic.mil/docs/citations/ADA550680http://www.dtic.mil/dtic/tr/fulltext/u2/a550680.pdfInverse synthetic aperture LADAR (ISAL) provides high resolution images which are not limited in resolution bythe diffraction limit of the telescope collecting the imaging data. This makes it an ideal method for imagingGeosynchronous Earth Orbit (GEO) space objects. Although LADAR is a well researched topic, little has beenpublished on the suitability of ISAL for imaging GEO space objects and the associated SNR models. This paperderives an expression for the return signal detected by a coherent ISAL system. Using tomographic techniquescommon to synthetic aperture radar (SAR), a model is developed for the signal-to-noise ratio of the reconstructedimage. Noise sources considered include photon noise and laser speckle noise.
Completed the President’s Mission Readiness Review for AFSPC11. Clean bird. Everything about this one is interesting. Too bad I can’t tell you anything about it...
Is there a confirmed launch time for this date?
