The confidence level in the new November 2018 date for the first launch of SLS (EM-1) is only 70%. This means that the project has about a 1-in-3 chance of slipping to 2019 or later, assuming no issues not already worked into the estimate crop up.The project was started in 2011, and the 2010 NASA Authorization Act required SLS to launch by 2016. It is now four years later, and the likely launch date for EM-1 has slipped to 2018 or later, a slip of two years in the first launch of SLS. That’s one year of schedule slippage for every two years that the project has existed. If the SLS schedule continues to slip at this rate over the next four years, the date of the first SLS launch will slip from 2018 to 2020. And then from 2018 to 2020, SLS will slip one more year or so before finally launching for the first time somewhere in the 2021-2022 timeframe.
