The National Aeronautics and Space Administration (NASA) is seeking to establish a sole source service contract with Hitachi High-Tech America, Inc. for the maintenance and operational support of the Hitachi S-5200 Scanning Electron Microscope (SEM) at the Langley Research Center in Hampton, Virginia. This contract, which will run from April 5, 2025, to April 4, 2026, is critical for ongoing research in materials processing and analysis, particularly in the characterization of nanomaterials. Interested organizations are invited to submit their qualifications by 7 a.m. CST on March 6, 2025, to assess potential competition, although the government retains the discretion to proceed with the sole source procurement.
