Japan to do test launch of its H3 rocket in June
Japan’s space agency JAXA is now planning a test launch on June 10, 2026 of its H3 rocket, carrying a dummy payload only in order to test the changes it has made in the rocket after a failed launch in December 2025.
The failure of the eighth H3 rocket was likely caused by an adhesion problem in the satellite mounting structure, which led it to break apart during flight, according to an investigation by JAXA. Similar issues were found in other units, prompting the space agency to fix them so the components can maintain their structural integrity.
In the June launch, a dummy satellite will be mounted on the test vehicle to collect data and verify the effectiveness of the measures. For future launches of actual satellites or space probes, JAXA plans to review the mounting structure design to reduce the risk of failure.
In other words, the method for attaching the payload to the rocket at some points failed, so that the satellite separated prematurely. The June launch will be to test a new mounting system.
Posting has been light the last few days as I deal with recovery from knee surgery.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
