Discussion Overview

The discussion centers around the cost-effectiveness and necessity of NASA's Space Launch System (SLS) in comparison to existing launch providers like SpaceX. Participants explore the implications of the projected costs, the capabilities of the SLS, and the rationale behind its development.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Budget analysis

Main Points Raised

  • One participant questions whether $18 billion for the first two SLS launches is justified, suggesting that SpaceX could provide similar launch capabilities for significantly less cost.
  • Another participant challenges this claim, pointing out that the SLS is still in development and that the long-term projected cost per launch is around $500 million, not $9 billion.
  • Some participants assert that no current launch provider can accommodate the size of the cargo intended for the SLS, emphasizing the necessity of its development.
  • One participant expresses confidence in NASA's ability to assemble components in orbit, suggesting a potential workaround for the SLS's limitations.
  • Several sources are cited to support claims about the budget and projected costs of the SLS, including a NASA report and analysis from a retired analyst, which indicate that the overall development costs could range from $29 to $38 billion.
  • A participant references a timeline for SLS launches, indicating expectations for the first launch in 2017 and subsequent launches every two years.
  • Another participant labels the SLS as a "pork project" imposed on NASA by Congress, suggesting skepticism about its funding and purpose.

Areas of Agreement / Disagreement

Participants express a range of opinions, with some agreeing on the limitations of current launch providers regarding cargo size, while others dispute the cost-effectiveness of the SLS compared to alternatives like SpaceX. The discussion remains unresolved with multiple competing views on the value and necessity of the SLS.

Contextual Notes

Participants reference various sources and reports, but there are unresolved assumptions regarding the long-term viability and actual costs of the SLS program. The discussion also highlights differing perspectives on the implications of government funding for space projects.

Is 18 billion dollars for the first two launches of the SLS a good buy? It seems NASA could buy the same weight to orbit today from Space-X for about 0.6 billion dollars. Why not just use the existing provider?
 
Physics news on Phys.org
First, do you have a source for your claims?

Second, you are aware that this is a project still in development, right? It isn't going to be just two launches at $9 billion apiece. It is projected at $500 million per launch, long term.

Third, even if your math is right Space-X (nor any other system) can't take cargo as large as SLS. That's the point of developing it.
 
I agree on the third point. But I am sure NASA is clever and can screw together two sub structures on orbit.
 
On the cost see the NASA report http://www.nasa.gov/pdf/510449main_SLS_MPCV_90-day_Report.pdf
from page 7 "The FY 2011 Senate Appropriations Report would fund the SLS at $1.9B in FY 2011, and with a
proposed cost cap of $11.5B through FY 2017. Within 60 days of enactment of the appropriations bill,
NASA is directed to submit a report that includes, among other things, an evaluation of this proposed cost cap."
 
More budget analysis from http://www.thespacereview.com/article/1979/1 by John K. Strickland, Jr. retired from his job as a senior analyst for the Texas Department of Transportation in Austin, Texas "Based on current development cost estimates for the SLS (including Orion) of $29–38 billion, even the (expendable) Falcon Heavy could launch between 300 and 400 payloads of 53 tons each for the same amount of money, starting in about two years."

Is NASA Building A Rocket They Can't Afford to Fly?
By Keith Cowing on May 24, 2013 12:47 PM
"The first SLS launch is expected in 2017, the second in 2021, and then once every two years thereafter."
 
FYI, SLS means Senate Launch System. It is yet another pork project foisted on NASA by Congress.
