The NASA Marshall Space Flight Center (MSFC) is modifying an existing contract to increase its ceiling value due to cost overruns from accelerated Artemis program work. The contract will also be extended by 12 months, structured as two 6-month option periods. This justification is publicized in advance of the modification, with the statutory authority citing only one responsible source. No specific budget amount or performance location is mentioned in the description. The effort supports returning Americans to the Moon under the Artemis program.
