About this opportunity
NASA's Marshall Space Flight Center issued a Justification for Other Than Full and Open Competition (JOFOC) on February 9, 2026, to extend the existing contract NNM15AA18C with BAE Systems, Inc. for continued mission operations and support of the Imaging X-ray Polarimetry Explorer (IXPE) through March 31, 2029. The sole-source extension, authorized under 10 U.S.C. 3204(a)(1), provides mission operations leadership, planning, and execution support for IXPE, a small employer class space mission launched in December 2021 that conducts X-ray polarimetry research on stellar objects including neutron stars, nebulae, and supermassive black holes. The justification for sole-source procurement is based on the unacceptable risks to spacecraft health, mission continuity, and scientific objectives that would result from transitioning to a new provider, with a pre-solicitation notice having generated no competing responses from other potential sources during the July 23 through August 7, 2025 posting period. The contract extension encompasses a 12-month Phase E base period from October 1, 2025 through September 30, 2026, two successive 12-month option periods through September 30, 2028, and a 6-month Phase F closeout period from October 1, 2028 through March 31, 2029. The specific award value for this contract extension was not disclosed in the published justification notice.
