Kirari ( Japanese きらり for sparkle ), also OICETS ( O ptical I nter-orbit c ommunications e ngineering t est s called atellite), is a 570 kg heavy Japanese Technology Experiment satellite for optical data transmission ( Laser Communication Terminal ), which a Dnepr - launcher on August 23, 2005 brought it from Baikonur to a near-earth orbit of approx. 600 km altitude.

Using lasers , he exchanged data in the near infrared range (800 nm wavelength ) with the Artemis satellite, about 40,000 km away . He could also address him conventionally by radio on the S-band . On June 7, 2006, optical communication with a DLR mobile ground station in Oberpfaffenhofen was also successful .

The mission was originally scheduled for a year, but Kirari worked for four years before being shut down on September 24, 2009.
