NASA: Two SLS Launches Likely Needed For $3 billion+ ARM, earlier post
“At today’s Small Bodies Assessment Group (SBAG) telecon, I asked Lindley Johnson via Webex “Can you show the chart again that has SLS as a launch option for the ARM spacecraft? Does this mean TWO SLS launches needed – one for ARM and another for crew?” He confirmed that yes, there will be two SLS launches – one SLS for the ARM spacecraft (Delta IV seems less desirable) and the other SLS for the crew. So … this $1.25 billion cap for the ARM mission ignores the $1 billion-plus cost of a SLS for the ARM spacecraft, and the $1 billion-plus cost of SLS/Orion. So … we’re looking at a $3-4 billion cost for the whole ARM effort.”
