 ==Cost overruns==
 The program has a long history of cost overruns.  Considering the cheaper commercial launch services, some consider it to be unaffordable for long term space exploration.<ref>https://www.space.com/nasa-sls-rocket-artemis-moon-plans-unaffordable-gao-report</ref>

-Leveraging NASA investments in Space Shuttle and Constellation Program hardware, the SLS launch vehicle comprises an 8.4-meter-diameter core stage, which is the same diameter as the Space Shuttle external tank. The core stage is flanked by two five-segment solid rocket boosters modified from the four-segment SRBs used on Shuttle. Core stage main propulsion will be provided by four RS-25E Space Shuttle main engines repurposed for the SLS application. The upper stage comprises a Delta (IV) Cryogenic Second Stage (DCSS) with a single RL10 engine, called the Interim Cryogenic Propulsion Stage (ICPS). The ICPS will eventually be replaced by a four-engine upper stage Advanced Cryogenic Evolved Stage (ACES).
