Pünktlich um 0652 UTC hob am 27.10.2005 die russische Trägerrakete Kosmos-3M vom Kosmodrom Plesetsk erfolgreich ab. Die Payload bestand aus den 6 Satelliten Mozhayets-5 (Russland), Sina-1 (Iran), dem chinesischen BEIJING-1 , dem englischen Erdbeobachtungssatellit TopSat , SSETI Express (European Space Agency) mit dessen weiteren 3 CubeSats NCube-2 (Norwegen), UWE-1 und XI-V (Japan). Auf der letzten Raketenstufe der COSMOS-3M Rakete ist eine weitere aktive Satellitennutzlast RUBIN-5 (SAFIR-S) installiert, die nach Aussetzen der primären und sekundären Satellitennutzlasten im Orbit verbleibt und technischen Experimenten dient.
Der Name von ISSL’s CubeSat ist “XI” ([ sai ] X-Faktor, Forscher). Abgeleitet von seiner quadratischen Form (XI bedeudet Domino auf japanisch) stellt er den nachforschenden Geist in Richtung zur Neuerkenntnis und zur Technologie dar.
