What Happened

Second Successful Launch For Japan's Flagship Rocket

The Japan Aerospace Exploration Agency successfully launched an H3 rocket carrying the Michibiki No. 7 positioning satellite into orbit, marking the second successful launch of Japan’s flagship rocket after a failure last December. The launch was initially scheduled for last Friday but was delayed due to a passing typhoon and inclement weather. The satellite is part of Japan’s Quasi-Zenith Satellite System, which provides location information for smartphones and vehicle navigation. The government aims to have seven such satellites in orbit to provide full service without relying on other countries. This launch was reported by Kyodo News.
