When I read that I went ebay shopping. They start around 2000. And no guarantee it comes with L. Then I hit up a buddy that collects and repairs old tube amps and such. Turns out its probably better to save up for a gram or so. We could all pitch in. Call it a kool aid fund. |

On Thursday morning, United Launch Alliance's Delta IV Medium rocket took flight for the final time. Beneath clear blue skies at the Cape Canaveral Air Force Station launch site in Florida, the rocket carried the GPS III satellite safely into orbit. This is the second of the Air Force's next-generation global positioning system satellites to reach space. As usual, the single-core Delta IV rocket performed its job well. Since 2002, this rocket (which can fly with or without small, side-mounted solid rocket boosters) has flown 29 missions. All have been successful. But the venerable Delta rocket will fly no more. Put simply, in today's marketplace—in which United Launch Alliance must compete with SpaceX for national security launches and with many other providers for commercial missions—the Delta-IV Medium cannot compete. A 2017 report by the US Government Accountability Office put the per-unit cost of a single-core Delta launch at $164 million. This is nearly three times the price of SpaceX's Falcon 9 rocket, which can not only be re-used but has comparable or better performance. To compete more effectively in this new landscape, United Launch Alliance is phasing out its use of heritage Delta and Atlas rockets in favor of a new Vulcan-Centaur rocket. In dropping the Delta IV Medium, the company is eschewing Aerojet Rocketdyne's costly RS-68A main engine in favor of the less-expensive BE-4 engine under development by the new space company Blue Origin. Similarly, it is seeking to cut costs on Vulcan in other ways, while maintaining its performance. This is not the last Delta rocket to fly, however. The US Air Force will continue to support the Delta IV Heavy program—which consists of three cores and is the second most powerful rocket in existence after the Falcon Heavy—until other heavy-lift alternatives emerge. The final flight for that vehicle is likely to come in 2024, when it lofts a heavy spy satellite for the National Reconnaissance Office. arstechnica.com/science/2019/08/the-last-single-stick-delta-rocket-launched-thursday-and-it-put-on-a-show/?amp=1 |
