The Japanese Aerospace Exploration Agency said Friday that it will delay the launch of a H-2A rocket carrying a spy satellite originally scheduled on Friday afternoon, due to unfavorable weather. The launch of the radar satellite from Tanegashima Space Center in south Japan's Kagoshima prefecture was aimed to complete the country's four-satellite system for intelligence gathering with full global coverage, reported Kyodo news agency. Once in orbit, the satellite, together with the other three, would be able to take pictures on any point of the earth surface at least once a day, according to media reports. The H-2A rocket was also to carry into space an experimental optical satellite for testing the functions of apparatus to be used to assemble a spy satellite scheduled for launch in the future. -- SPA
