1. Solar-B Launch Operations Scenarios ISAS/JAXA Solar-B project Prepared by T. Shimizu For Wallops face-to-face meeting

2. Launch operation

3.  longitude of ascending (north-bound) node, which defines at what longitude Solar-B crosses the earth equator Solar-B will be launched from USC (Kagoshima Uchinoura Space Center, Japan). Launch window: 21:32:46-21:41:04 UT in 23 August 2006 to 26 September 2006. The initial orbit to be installed by a M-V rocket is as follows:

6. Solar-B Battery In case that the solar array paddle is not deployed, the battery can supply the power for 160 min.

7. Orbit maneuvers for sun-sync. polar orbit

8. Solar-B will be finally installed to the sun-synchronous polar orbit with maneuver operation in the next page.
