The H3&#8217;s upper stage failed to ignite a few minutes after liftoff, causing the rocket and its Earth observation payload to crash into the Pacific Ocean.<\/p>\n<p>Officials in the Japanese government are already plotting the replacement for the H3 rocket, which had a goal of cutting in half the cost per launch of the H-2A launcher, a workhorse for Japan&#8217;s space program. But the H3 is based on a single-use, expendable design, like nearly all legacy rockets. The H3 design aims to achieve these cost savings through modernized manufacturing techniques and commonality in hardware with Japan&#8217;s smaller Epsilon rocket family.<\/p>\n<p>The Japanese government updated its <a href=\"https:\/\/www8.cao.go.jp\/space\/plan\/keikaku.html\">basic plan on space policy<\/a> in June with language endorsing the development of a reusable rocket to follow the H3. Now, the Japan Aerospace Exploration Agency (JAXA) has tapped Mitsubishi Heavy Industries for joint studies on the next-generation launcher, which would have a recoverable and reusable first-stage booster, <a href=\"https:\/\/spacenews.com\/japan-conducting-studies-for-reusable-next-gen-rocket\/\">Space News reported<\/a> this week.<\/p>\n<\/div>\n<p><a href=\"https:\/\/arstechnica.com\/?p=1973400#p3\">Read 16 remaining paragraphs<\/a> | <a href=\"https:\/\/arstechnica.com\/?p=1973400&amp;comments=1\">Comments<\/a><\/p>\n<p>&#013;<br \/>\n&#013;<br \/>\nSource: Ars Technica &#8211; <a href=\"https:\/\/arstechnica.com\/?p=1973400\" target=\"_blank\" rel=\"noopener\">Japan is studying a reusable rocket, but it won\u2019t fly before 2030<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Enlarge \/ Japan&#8217;s first H3 rocket lifted off from the Tanegashima Space Center on a failed test flight in March.
