One month has past since Deep Space Sculpture “ARTSAT2:DESPATCH” was put into an Earth-escape orbit as a piggyback payload of H-IIA F26 launched at December 3, 2014 from Tanegashima Space Center, JAXA. It is estimated to have stopped sending radio waves since the battery of DESPATCH already ran out (We predicted that the battery will work for 27 days according to the running time of the transmitter).<\/div>\r\n
\r\n
Today January 3, the main control station, Tama Art University Ground Station, decided to conclude the operation of DESPATCH. Many people supported and cooperated us throughout the design and development of DESPATCH. In addition, many excellent many ham radio operator received and reported super weak radio waves of DESPATCH from deep space. To have this opportunity, I would like once again to thank all of them very much.<\/div>\r\n

Reception reports of DESPATCH are summarized on the following page.<\/div>\r\n

Finally, we had two reception reports at 4.7 million kilo-meters from the Earth (more than 12 times of the distance to the Moon). They were far beyond what we expected. They are the the longest communication distance in the world between two amateur radio stations.<\/div>\r\n

Orbital elements of DESPATCH is as follows (J2000 heliocentric ecliptic coordinates).<\/div>\r\n\r\n
