Japan's space agency announced the successful launch of its new flagship rocket on Saturday, making it third time lucky for the H3 after years of delays and two previous failed attempts. The H3 rocket, billed as flexible and cost-effective by space agency JAXA, "was put into orbit," a JAXA official told AFP. Developed jointly by JAXA and Mitsubishi Heavy Industries, the H3 is the successor to the H-IIA launch system, which debuted in 2001.
