The National Aeronautics and Space Administration (NASA) is seeking to extend the Engineering Services and Science Capability Augmentation (ESSCA) Contract with Jacobs Technology Incorporated, doing business as Amentum, to ensure continued support for critical engineering and scientific services at the Marshall Space Flight Center in Huntsville, Alabama. This extension, which will last for an initial six months from December 1, 2025, through May 31, 2026, is essential for maintaining uninterrupted support for NASA programs, particularly the Space Launch System (SLS) and Human Lander System (HLS), during key phases of ongoing missions. The decision to pursue a sole source contract extension is based on the unique expertise and knowledge Amentum possesses, which is vital for mission success and crew safety, especially for the upcoming Artemis II mission. Interested organizations may submit their capabilities and qualifications to Jennifer Chrissis at jennifer.l.chrissis@nasa.gov by 4 pm Central Time on January 6, 2025, for consideration in this procurement process.
