NTU scientists make contact with X-SAT The launch of the X-Sat satellite may help the Republic grow its space industry. On April 20, X-Sat blasted off into orbit, riding on an Indian rocket. NTU scientists have since established contact with the 105kg micro-satellite in space in less than 10 hours after launch. The telemetry received by the team from the first-ever satellite built from scratch in Singapore by NTU and DSO Laboratories, show that it is in good working condition with its solar panels deployed and operating well. NTU president Su Guaning said after X-Sat's successful blast-off, the satellite launch represents a 'huge leap' for Singapore's research efforts in space technology and building micro-satellites.
