|Name (pre-launch in parentheses)||HINODE (SOLAR-B)|
|International Designation Code||2006-041A|

|Launch||Date||06:36, September 23, 2006 (JST)|
|Location||Uchinoura Space Center (USC)|
|Configuration||Weight||Approx. 900 kg|
|Dimensions||Approx. 1.6m x 1.6m x 4m
10m long from end to end of solar array paddles

|Orbit||Altitude||Approx. 680 km|
|Type of Orbit||Circular (Sun-synchronous polar)|
|Operation||Observations with the scientific instruments started after opening their protective doors in late October, 2006. Scientific operations are conducted from the ISAS facility located in Sagamihara, Japan, with participation of scientists from international instrument teams. Hinode is operated as a solar observatory on orbit and its observations are scheduled with Hinode core team programs and proposal programs including coordinated observations with ground-based observatories and space missions. The data from these observations are also freely available as soon as after their acquisition.
Hinode is a Japanese mission developed and launched by ISAS/JAXA, with NAOJ as domestic partner and NASA and STFC (UK) as international partners. It is operated by these agencies in co-operation with ESA and NSC (Norway).
|Results||All the three scientific instruments have been acquiring image data with supreme performances never realized so far, such as high (0.2-0.3 arcsec) spatial resolution and precise magnetic-field measurement of SOT, which are expected to advance many of the solar physics researches significantly. From observations made in initial observing phase, several numbers of discoveries have been made, such as Alfven waves in the corona, unexpected dynamics in the chromosphere and photosphere, continuous outflowing plasma as a possible source of solar wind, and fine structures of magnetic field in sunspots and solar surface. They all help us to understand physical mechanisms of phenomena occurring in the solar atmosphere. Scientific results were featured as Hinode special issue in the U.S. “Science”, Japanese “Publications of the Astronomical Society of Japan”, and European “Astronomy & Astrophysics”.|
