The Japan Aerospace Exploration Agency would like to announce that the Small Demonstration Satellite-1 (SDS-1) was moved to the initial functional verification operation(*2) after completing its critical operation(*1) on January 27, 2009 (Japan Standard Time, JST). The SDS-1 was launched as a piggyback satellite with the Greenhouse Gases Observing Satellite "IBUKI" (GOSAT) by the H-IIA Launch Vehicle No.15 at 12:54 p.m. on January 23, 2009 (JST).

The satellite is currently in good condition.

We are carrying out the initial functional verification for about one month.
