Following NASA\u2019s Office of Inspector General (OIG) releasing a report on October 10 of their audit of the agency\u2019s management of the Space Launch System (SLS) Stages contract, NASA has reacted by confirming they have already taken measures to assure that there is not a stoppage of work on the SLS Stages. The OIG concluded that the cost of the work under the development contract with Boeing was likely to be much higher than its existing value and that it was unlikely that NASA will meet the end of its current target window for the first SLS launch on Exploration Mission-1 (EM-1).<\/p>\n

The report also noted that existing contract only covers the stages for two SLS Block 1 vehicles, adding that there is no stage on contract yet for one of the two recently rescheduled launches.\n<\/p>\n

Current contract money runs out soon<\/p>\n

The OIG report noted that the full value of the existing contract could be reached by early next year, as the pace of milestones to complete the first Core Stage needs to increase.<\/p>\n

Stages prime contractor Boeing hopes to complete outfitting the individual sections of the first Core Stage by the end of the year, with final assembly of the stage in the first half of 2019. By the IG Office\u2019s estimate of Boeing\u2019s run rate, the full value of the existing contract will have already been paid before work reaches the final assembly phase.<\/p>\n

OIG noted that the SLS Program has used some program reserves to help this fiscal year, but it\u2019s likely the existing contract will need to be renegotiated again and OIG recommended both a renegotiation and specific contract terms.<\/p>\n

Bill Gerstenmaier, NASA Associate Administrator for the Human Exploration and Operations Directorate (HEOMD), wrote in a response included in the report: \u201cThis recommendation will be satisfied, to the extend practicable, by contract restructure, which includes the appropriate approvals by Boeing management and NASA officials.\u201d<\/p>\n

\u201cNASA has already taken measures to assure that there is not a stoppage of work on the SLS Stages,\u201d NASA spokesperson Kathryn Hambleton added in an email. \u201cThese measures include issuance of an Undefinitized Contract Action (UCA) to continue performance until we can get a new delivery schedule negotiated and definitized.\u201d<\/p>\n

The current contract extends through the end of calendar year 2021 and calls for delivery of two SLS Core Stages and one Exploration Upper Stage (EUS) at a cost of $6.2 billion US. The OIG report concluded that the cost to complete production of the first Core Stage next year, take it through the Stage Green Run test campaign by the end next year, and then launch it in 2020 would overrun the full amount obligated through 2021.<\/p>\n

Of the seven recommendations in the OIG report, NASA concurred with six of them, and the report noted that agency management had begun implementing some changes prior to this year\u2019s audit. The OIG report estimates that work through the current contract period will ultimately cost $8.9 billion US.<\/p>\n

Contract gap could affect future manifest<\/p>\n

One of the previous renegotiations of the current Stages contract also added development of the EUS and production of one unit to development of the Core Stage and production of two of those units. At the time of that contract modification in early 2017, the EUS was planned to fly with the second and last contracted Core Stage.<\/p>\n

\"\"<\/p>\n

The early flight manifest for SLS changed again in reaction to funding by the U.S. Congress of a second Mobile Launcher in late March; EUS was pushed back to the fourth SLS flight, with three launches now planned for the initial Block 1 vehicle. The change created a disconnect with the renegotiated work that included flying the first EUS under the current contract, but also created a shortage of contracted Block 1 stages.<\/p>\n

SLS currently has only two Core Stages and one ICPS under contract to fly three Block 1 flights.<\/p>\n

NASA is currently mandated to fly Europa Clipper on SLS by 2022 and a fully crew-capable Orion spacecraft is planned to be ready for the EM-2 mission in the same time frame; the most recent public schedule from the agency projected EM-2 flying in 2022 and Europa Clipper in 2023.<\/p>\n

There were signs that the process of procuring future stages under a more production-oriented contract had started early in the year; however, the OIG report says that \u201cDue to NASA\u2019s focus on overcoming the challenges associated with the current Boeing Stages contract and ensuring delivery of the first two Core Stages, the Agency has yet to implement an acquisition strategy for acquiring additional Core Stages beyond Core Stage 2.\u201d<\/p>\n
