NASA has asked the US aerospace industry how it would go about "maximizing the long-term efficiency and sustainability" of the Space Launch System rocket and its associated ground systems.
In its request NASA says it would like to fly the SLS rocket for "30 years or more" as a national capability. Moreover, the agency wants the rocket to become a "sustainable and affordable system for moving humans and large cargo payloads to cislunar and deep-space destinations."
How does one make a system that has been anything but affordable and sustainable into something that is affordable and sustainable? NASA says it wants to transition ownership of rocket production and ground services to the private industry. In return, this private contractor should build and launch the SLS at a substantial savings of 50 percent or more off of the current industry "baseline per flight cost."
Notably, NASA has never publicly stated this baseline flight cost. Ars asked the NASA communications office on Tuesday for this figure, but as of Wednesday morning there has been no response. In 2019, the White House Office of Management and Budget
estimated the cost of one SLS launch a year at "over $2 billion." Subsequently
NASA did not deny that figure, but it has not been transparent with taxpayers about the rocket's expected costs.
Anyway, NASA now proposes to cut this cost—whatever it is—in half. And it seeks to fly the Space Launch System rocket well into the middle of the 21st century.
This may be theoretically possible, although the agency's history with the large rocket has been shown to be full of wildly over-optimistic assumptions. When the SLS rocket was conceived in 2010 and formally announced in 2011, it was supposed to be launched by the end of 2016 and developed for $10 billion.
Among the rocket's chief architects was then-Florida Senator Bill Nelson, who steered billions of dollars to Kennedy Space Center in his home state for upgraded ground systems equipment to support the rocket. Back in 2011, he proudly said the rocket would be delivered on time and on budget.
“This rocket is coming in at the cost of... 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. This costs $10 billion for the rocket.” Later, he went further,
saying, "If we can't do a rocket for $11.5 billion, we ought to close up shop."
After more than 10 years, and more than $30 billion spent on the rocket and its ground systems, NASA has not closed up shop. Rather, Nelson has ascended to become the space agency's administrator.
