According to foreign media reports, a report released recently by NASA's inspector general's office shows that,If current cost overruns and delays persist, NASA's ambitious plan to send humans to the moon in 2024 looks increasingly expensive and less likely.
"NASA's ongoing efforts to manage the cost and schedule of SLS projects may affect the agency's ambitious goals for Artemis," the report said yesterday. For Artemis i-stages, ICPs, boosters, rs-25adaptation and rs-25 restart, each major element contract for the development and construction of SLS has experienced a large number of technical challenges, performance problems and demand changes, which caused a cost overrun and increase of 2 billion US dollars and a schedule delay of at least 2 years. "
But that doesn't mean the 2024 schedule has been delayed to 2026 - the delay is due to the construction of the first SLS beta. The first launch of the rocket is expected in the spring of 2021, more than two years later than originally estimated.
In fact, the SLS project started in 2010 and the design phase ended in 2014, after which the testing and manufacturing contract was awarded. Although NASA put forward a date of readiness as early as 2016, the agency's final official commitment is by the end of 2018. But the reality is that the date has been pushed back. What's more, these delays and difficulties complicate the financial issues, leading to the cost of the project exceeding the original budget.
Overall, NASA will spend more than $17 billion on SLS projects by the end of fiscal year 2020, including nearly $6 billion that has not been tracked or reported, the report said.
It's much more difficult and expensive to speed up the moon landing than people initially thought. In the end, for Artemis, it is important that the United States can return to the moon in a safe and timely manner.
