Helium is used to pressurize tanks and help push fuel into the engines. Without proper helium flow, the rocket cannot safely fly. Because the upper stage is hard to reach at the launchpad, NASA rolled the stacked rocket back into the Vehicle Assembly Building, the sky-scraping hangar where it was originally put together.

The Artemis III mission, which had been expected to land astronauts near the moon's south pole in 2028, now will be redefined and rescheduled — launching in 2027 but not to the moon, Isaacman said. Instead, the yet-to-be-named astronauts will rendezvous and dock in orbit closer to home with one or both of the commercially built lunar landers now under development at Elon Musk's SpaceX and Jeff Bezos' Blue Origin.
在传统存储产品方面，10nm以下DRAM制造工艺正成为主流，并逐步向7nm工艺突破，通过“FinFET架构+TSV技术”提升密度、降低功耗。3D NAND堆叠层数突破400层后，“垂直堆叠”难度加剧，厂商转向“水平扩展+架构优化”，比如三星V-NAND的阶梯式架构、Kioxia的BiCS架构，同时引入“HKC（高K介质+金属栅）”技术，解决高层数堆叠的漏电、散热问题，制造工艺从“层数竞赛”转向“架构+工艺”双重竞争。
