About this opportunity
NASA's Goddard Space Flight Center seeks development and production of the Sounder for Microwave-Based Applications (SMBA), a passive microwave sensor instrument for near-earth orbit atmospheric profiling, with proposals due June 1, 2026. This is a full and open competition under NAICS 334511 with no set-aside.
Place of performance is the United States. The contract structure spans three CLINs: CLIN 0001 is Cost-Plus-Fixed-Fee covering non-recurring engineering, engineering development, and Flight Model 1 production through launch plus 6 months; CLIN 0002 is Firm-Fixed-Price for Flight Models 2 and 3 production through bench acceptance testing; and CLIN 0003 is Time-and-Materials for post-commissioning support and special studies with a cumulative ceiling of $52.8 million. Anticipated award is November 5, 2026.
The SMBA instrument must operate across approximately 20–300 GHz frequency bands (K, Ka, V, W, F, D, G, and J bands) with over 100 hyperspectral channels, noise equivalent delta temperature requirements specified by band, real-time radio frequency interference detection, mass not exceeding 150 kg, orbital average power of 295 W maximum, and geolocation accuracy of 1.50 km radial at nadir. The instrument design life is 5 years in sun-synchronous orbit at 824 km altitude. Flight Model launch dates are October 1, 2034 (FM1), October 1, 2037 (FM2), and October 1, 2040 (FM3).
Contractors must implement AS9100 Revision D quality management systems, comply with NASA and industry standards covering workmanship, materials, processes, metrology, and calibration, conduct comprehensive environmental and compatibility testing, and support satellite-level integration, launch operations, and on-orbit commissioning. The contractor must maintain an Integrated Master Schedule, implement an Earned Value Management System compliant with EIA-748, and demonstrate financial capability and an adequate accounting system. Small business subcontracting goals are 8.7% small business, 0.8% small disadvantaged business, 1.0% women-owned small business, 0.6% veteran-owned small business, with smaller percentages for HUBZone, service-disabled veteran-owned, and HBCU/MSI categories.
Evaluation emphasizes mission suitability (1,000-point scale: 500 points technical approach, 400 points management approach, 100 points small business utilization), past performance, and cost/price, with mission suitability significantly more important than cost. Proposals must address technical requirements, manufacturing and integration approaches, system performance, calibration methodology, safety and mission assurance, management and risk mitigation, schedule, and subcontracting strategy in four volumes: Offer, Mission Suitability (105-page limit), Cost/Price, and Past Performance (25 pages). Contracting Officer is Bruce Tsai (Bruce.B.Tsai@nasa.gov); questions were due April 15, 2026. The RFP includes three amendments effective through May 7, 2026, addressing supply chain visibility reporting, cost exhibit revisions, FAR clause updates including DEI discrimination prohibition (52.222-90), and clarifications on payment milestones and cost responsibility between CLINs.
