Delta IV Heavy rocket delayed again, raising concerns of aging infrastructure
- throwmeaway_pls 6y agoWhere does all the money actually go? Headcount? Long development cycles? Does anybody have any insight? I know there’s a trite answer, but what is really happening?
- pengaru 6y agoTFA clearly states this launch facility is effectively deprecated, ULA is investing in facilities more relevant to their future needs.

- NikolaeVarius 6y agoWhat do you mean? Things cost money to maintain. The D4H is a best in class rocket that is rated for the highest reliability requirements. As long as the D4H is flying, no matter infrequently, they need to maintain personnel, equipment, knowledge. A scrub requires defueling, refueling, maintenance, and all the infra associated around that, Also since Vulcan development has started, most resources are being put into that, so the D4H stuff is being sidelined, even though its still launching critical missions
- sebazzz 6y agoWho pays for delays? Is it that calculated in the price of the the launch, or covered by insurance?
- Shivetya 6y agoon a side note, a hot fire abort is just so bizarre to see let alone listen to launch control when it happens[0]. Everything seems to just "stop" [0]https://youtu.be/wI7IcIDRoXo?t=306 https://youtu.be/wI7IcIDRoXo?t=306
- NikolaeVarius 6y agoThe shuttle had a neat hot abort https://www.youtube.com/watch?v=eeWtfSlH35A https://www.youtube.com/watch?v=eeWtfSlH35A
- n3k5 6y agoThis seemed comparatively unspectacular at first. But I'm not savvy enough to make out terms such as ‘RSLS abort’ in the dialogue (let alone knowing what they mean); luckily I quickly found a noob-friendly write-up that filled me in: https://en.wikipedia.org/wiki/STS-41-D#Launch_attempts https://en.wikipedia.org/wiki/STS-41-D#Launch_attempts > While evacuating the shuttle, the crew was doused with water from the pad deluge system, which was activated due to a hydrogen fire on the launch pad caused by the free hydrogen (fuel) that had collected around the engine nozzles following the shutdown and engine anomaly. Because the fire was invisible to humans, had the astronauts used the normal emergency escape procedure across the service arm to the slidewire escape baskets, they would have run into the fire. Whoa ◎﹏⊙. Not quite what I'd call ‘neat’.
