The Japanese rocket startup Space One has now scheduled the third launch attempt of its Kairos rocket for this coming Sunday, March 1, 2026, lifting off from its private Spaceport Kii launchpad.
Space One said Friday that it would launch the No. 3 unit of its Kairos small rocket carrying artificial satellites on Sunday morning. The Tokyo-based space development startup canceled the initially scheduled launch on Wednesday, citing a forecast for unfavorable weather conditions.
According to Space One, the Kairos No. 3 unit is set to lift off from the company’s Spaceport Kii launch site in the town of Kushimoto, Wakayama Prefecture, between around 11 a.m. and 11:20 a.m. on Sunday. The rocket will carry five satellites, including one developed by the Taiwan Space Agency.
The two previous launch attempts, in March and December 2024, both failed almost immediately after launch.
A success now by this private company is crucial for Japan, as its government-owned H3 and Epsilon rockets are both grounded due to launch failures.
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
