About this opportunity

Written by GovTribe AI · Oct 9, 2026

NASA Johnson Space Center is soliciting responses to a draft request for proposal (DRFP) for the Commercial Low Earth Orbit Destination Contract (CLDC), with comments due July 27, 2026, and final RFP release anticipated for late August 2026. This is not a live solicitation; no proposals should be submitted to the DRFP. The procurement is not set-aside.

The CLDC will acquire end-to-end services from a commercially owned and operated Low Earth Orbit destination to succeed the International Space Station and sustain human presence in LEO for crew science and exploration. The contractor will design, build, and operate a Commercial LEO Destination System encompassing all development and certification activities, manufacturing, demonstration and testing, transportation vehicles (cargo and crew), operational missions, and post-certification utilization.

The contract structure is a Multi-Award IDIQ with Firm-Fixed-Price task orders. Five Contract Line Item Numbers (CLINs) define the work: CLIN 1 (Initial Development through Critical Design Review Plus), CLIN 2 (Development, Demonstration & Certification), CLIN 3 (Mission Services with three mission types—30-day crew-tended, 6-month continuous crew with reduced utilization, and 6-month standard continuous crew), CLIN 4 (Pre-Priced Additional Services), and CLIN 5 (Special Tasks and Studies). NASA intends to award CLIN 1 to a minimum of two providers with a minimum $100 million buy, followed by competitive task order selection. Base ordering period is 8 years with four option periods extending to 15 years total. Contract award is anticipated for early Spring 2027.

Performance includes design, manufacturing, testing, launch, deployment, demonstration, and certification of systems supporting a minimum four-person crew (including at least two U.S. Government crew members). NASA's utilization requirements span three capability tiers with specific cargo volume and locker allocations. The contractor must provide crew and cargo transportation, habitability, training, operations, utilization support, and medical operations. NASA retains first right of refusal for 70 percent of available cargo capacity and crew commander roles on each mission.

Contractors must obtain National Security Facility Clearance Levels up to TOP SECRET and provide personnel with SECRET/TOP SECRET clearances. Work is performed at contractor facilities with some work potentially at NASA centers under Government Collaboration Agreements and Government Task Agreements; NASA is offering up to 20 NASA personnel at no cost to support collaboration. NAICS code 336414 (Guided Missile and Space Vehicle Manufacturing) applies; small business size standard is 1,300 employees.

Proposals must be submitted through NASA's FedRAMP Moderate-certified Enterprise File Sharing and Sync Box platform. Comments on the DRFP must be submitted electronically to Ashley Chaves at jsc-cldc@mail.nasa.gov by July 27, 2026 at 8:00 AM Central, referencing solicitation number 80JSC026R0021 DRFP. Pre-proposal conference was held July 9, 2026; one-on-one meetings with prime offerors and transportation providers occurred July 13–15, 2026 at Johnson Space Center Building 111. Industry Q&A rounds addressing commercialization, launch vehicle requirements, contract type, crew selection, cross-waiver provisions, and data rights have been posted. The CLDC Interested Parties List identifies 51 organizations with expressed interest. Final RFP and all related documents will be posted on SAM.gov; offerors must monitor that website for release and amendments.
