ULA completes last Delta-4 Heavy launch
Delta-4 Heavy on its last launch
ULA today successfully completed the last Delta-4 launch, the Delta-4 Heavy version — the most powerful — lifting off from Cape Canaveral and placing a National Reconnaissance Office surveillance satellite into orbit.
From this point on ULA will rely on its new Vulcan-Centaur and Atlas-5 rockets, though production of the Atlas-5 has ceased. When the remaining Atlas-5s are flown, the Vulcan-Centaur in its many iterations will become the company’s mainstay rocket. All this might change depending on who buys ULA. If Blue Origin buys the company, the mix will be more complex, as that company is developing its own New Glenn rocket.
This was ULA’s second launch in 2024, so there is no change to the leader board in the 2024 launch race:
36 SpaceX
14 China
5 Russia
4 Rocket Lab
American private enterprise now leads the rest of the world combined 42 to 25, while SpaceX by itself leads the rest of the world, including other American companies, 36 to 31.
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. from any other book seller, or direct from my ebook publisher, ebookit.
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
