Dhaka, June 29 -- Japan on Sunday successfully launched a climate change monitoring satellite on its mainstay H-2A rocket, which made its final flight before it is replaced by a new flagship model designed to be more cost competitive in the global space market.

The H-2A rocket lifted off from the Tanegashima Space Center in southwestern Japan, carrying the GOSAT-GW satellite as part of Tokyo's effort to mitigate climate change. The satellite was safely separated from the rocket and released into a planned orbit about 16 minutes later.

Scientists and space officials at the control room celebrate the successful launch, which was delayed by several days due to a malfunctioning of the rocket's electrical systems, according to AP.
