However, a source said the best-case scenario for launching the Artemis 1 mission is spring of next year, with summer being the more realistic target for a test flight of the heavy lift rocket and Orion spacecraft. The space agency is already running about two months behind internal targets for testing and integrating the rocket at Kennedy Space Center, and the critical pre-flight tests remain ahead.
NASA's Kathryn Hambleton acknowledged that the space agency has seen schedule slips. "The agency continues to monitor the rise of COVID cases in the Kennedy area, which, combined with other factors such as weather and first time operations, is impacting our schedule of operations," she said. "Moving step by step, we are progressing toward launch while keeping our team as safe as possible."
"This rocket is coming in at the cost of what not only what we estimated in the NASA Authorization act, but less,” Nelson said at the time. “The cost of the rocket over a five- to six-year period in the NASA authorization bill was to be no more than $11.5 billion.” Later, he went further, saying, "If we can't do a rocket for $11.5 billion, we ought to close up shop."
More than a decade later, NASA has spent more than $20 billion to reach the launch pad. And Nelson is no longer a US Senator—he is the administrator of the space agency. The shop remains open.
Welp, more delays and I hope it still happens but it's not looking good if it continues.The SLS rocket won't fly until 2022 at the earliest
