I thought that it was time to start a new thread devoted to the JUNO Jupiter
Orbiter mission. This New Frontiers Mission #2 seems to be a "stealth" project with little information available on the Web. In fact, the official NASA JUNO web site is quite pitiful. It contains the minimal amount of information on what seems to be an intriguing mission, in terms of both science and engineering. Does the UMSF community have information on this mission that has not been widely seen before? Another Phil |

Just to keep you up to date, here an excerpt of a still ugly-looking intermediate calibration step for EFB15:
Data-reduced EFB15 , Simulated BSC5p, visual magnitude < 5 , Combined for RANSAC . This 0th approximation, the above images are an excerpt of, inferes 4 parameters (3 rotational and 1 optical) automatically by a RANSAC-like algorithm with nested hill-climbing, actually any 2 of the 10 brightest reduced EFB15 spots are identified with any 2 of the 15 brightest BSC5p stars. The above simulated image is number 17 of 34 combinations within "reasonable" constraints of a total of roughly 10,000 tries. Other parameters are inferred manually from images or are intentionally guessed or set to defaults. They will be pinned down in consecutive optimization steps. Used BSC5p data: bsc5p_equatorial_less_vmag5_sortby_vmag.txt ( 112.93K ) Number of downloads: 487 Simulated BSC5p positions of this run: BSC5_SpotTab_Match00017_Simulated.txt ( 44.91K ) Number of downloads: 503 Intermediate BSC5p star assignments to EFB15 spots (RANSAC consensus set) as a result of this run: BSC5_SpotTab_Match00017_Actual.txt ( 16.98K ) Number of downloads: 338 (contains cumulative data of the first 17 "reasonable" runs) Data source for stars: Bright Star Catalog, 5th Edition, preliminary J2000.0 |
