                                                        07/21/2014                                 Despite efforts to keep the flagging VUSat OSCAR-52 (VO-52) Amateur Radio satellite in operation for a while longer, ground controllers have yielded to the nearly decade-old spacecraft’s failing technology and have permanently taken it out of service. Launched into low Earth orbit in 2005, the VO-52 microsatellite carried two Amateur Radio transponders for SSB and CW. B.A. “Mani” Subramani, VU2WMY/KJ6LRS, of the Indian Space Research Organisation (ISRO) said that VO-52’s lithium-ion batteries had failed, and the satellite was officially decommissioned on July 21.
