Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the Draft Request for Proposal (DRFP) for the Mars Telecommunications Network (MTN), Solicitation 80GSFC26R0011.

• Test Assets: NASA intends to provide access to test assets for compatibility testing, but this will need to be negotiated.
• Delivery Date: December 31, 2028, is the "no later than" delivery date for the ground and flight systems, driven by statutory requirements.
• DWE Link: The Deep Space Network (DSN) link is two-way, supporting both forward and return communications. Autonomous navigation is a goal to reduce ground element dependence, not solely for Doppler data.
• Full Operational Readiness: This means spacecraft checkout and commissioning are complete at Mars, and the system is ready for nominal operations in the planned end-state orbit.
• Data Transfer: "Continuous and full rate data transfer" applies only when the links are active.
• Ranging Precision: "Precision" refers to measurement noise from link budget and transponder, not accuracy metrics like per-pass range bias.
• Proximity Link Availability: The link needs to be available when active but can be degraded during maneuvers.
• Autonomous Navigation: The capability can be added later in the mission life, but the hardware and compute capacity must be sufficient.
• Electra Radios: These radios meet the requirement for open-loop recording and closed-loop demodulation.
• User Types: Example users include legacy surface assets, small science orbiters, new surface assets, and Entry Descent and Landing (EDL) demonstrations.
• DRDs: NASA acknowledges the number of Data Requirements Deliverables (DRDs) is a driver and expects them to be reflected in pricing.
• FAR 52.217-8: The Option to Extend Services clause has been removed from the final RFP.
• Payment Evaluation: Advanced payments will be evaluated neutrally.
• Software DRDs: Software DRDs are associated with Ground Systems software, not spacecraft or payloads.
• $700M Ceiling: The $700M ceiling applies to the contractor's total evaluated price, not NASA internal costs.
• T&M Task Orders: NASA retains the ability to unilaterally issue Time and Materials (T&M) task orders, and vendors are required to bid them.
• Launch Vehicle: Offerors must propose on CLIN 0003 (Launch, Integration, and Orbit Insertion).
• Proximity Link Frequencies: Frequencies meet SFCG recommendations and will be coordinated with relevant authorities.
• Scheduling: "Human-in-the-loop" is not required for scheduling; it's for coordinating multiple users.
• Science Payload: The science payload will not drive pointing, steering, or orbit selection. Packaging flexibility exists within the provided envelope. A steady-state 100% duty cycle is assumed for power budgeting. UHF is required for legacy systems.
• Verification Oversight: NASA requires technical insight into verification events and test activities, with specific oversight defined in a plan.
• Resident Officer: Specific residency details will be defined in the Insight and Oversight Implementation Plan.
• Launch Commit Criteria: NASA will develop LCC for the SMD payload and needs to approve LCC related to the spacecraft and launch vehicle.
• Launch Manifest: Contractor is responsible for coordinating launch manifest requirements and window constraints with the launch provider.
• Flight Software: NASA will use identified safety-critical and mission-critical flight software information to maintain insight into system functionality.
• Verification Closure: NASA will provide oversight and approval of verification closure notices.
• Full Operational Readiness Definition: Spacecraft checkout and commissioning complete at Mars, ready for nominal operations.
• Option to Extend Services Notification: NASA will provide 30 days advance notice through routine status meetings.

These clarifications address numerous technical and programmatic questions, potentially impacting bidder understanding of requirements, cost estimations, and proposal strategies. Key areas clarified include delivery timelines, operational concepts, system capabilities, and contractual clauses.

Questions & Answers / Clarifications

This document contains responses to questions raised by industry regarding the Mars Telecommunications Network (MTN) opportunity. It clarifies various aspects of the procurement, requirements, and timelines.

• Procurement Timeline: While specific dates are not fully detailed, the launch is expected in late 2028 CY. Comments on the Draft RFP (DRFP) were due April 13, 2026.
• Digital Engineering: Providers must comply with IT requirements outlined in the contract.
• NASA's Role: NASA will take ownership of the MTN system, with the approach being Government owned and Contractor operated. NASA will accept delivery of the spacecraft data package and final delivery upon successful commissioning at Mars.
• Funding: MTN is funded by public law and is assumed to be independent of budget changes, though not 100% certain.
• Proximity Links: X-band can be used for proximity links, and the Ground Rules have been updated to reflect this. NASA has completed a trade study favoring S and K/Ka bands but is open to feedback. Concerns exist regarding potential interference with other X-band users at Mars.
• DSN Availability: While studies suggested avoiding the Deep Space Network (DSN), current requirements dictate DSN use. MTN will be a high priority mission and will receive needed DSN time, but providers can design spacecraft to use commercial ground stations.
• Award Strategy: NASA expects to issue a single award for this opportunity to mitigate risks associated with multiple awards, such as funding limitations and schedule complexities.
• AI Systems: No aspect of MTN has been determined to be a covered AI system. However, AI disclosure requirements are still being worked out.
• Electra Radios: NASA can provide two new Electra radios as Government Furnished Equipment (GFE) to meet proximity UHF requirements.

This Q&A document provides crucial clarifications that may influence how potential bidders prepare their proposals, particularly regarding technical requirements, operational approaches, and contractual obligations. The updates to the Ground Rules and the clarification on X-band usage are significant for technical design considerations.

This document is a Past Performance Questionnaire intended for use by evaluators to assess a contractor's past performance relevant to a Statement of Work (SOW). It guides evaluators in providing descriptive information about the contract, the evaluator, and the contractor's performance.

• Contract Information: Details about the contract being evaluated (name, address, Cage Code/DUNS, contract number, type, period of performance, total contract value, award information).
• Description of Contract: A brief description of services provided and the firm's role (Prime Contractor, Subcontractor, Team Member).
• Evaluator Information: Details about the person completing the questionnaire.
• Survey Relevance Ratings: A section to mark which elements of the SOW were performed or not performed by the contractor.
• General Performance Survey: Ratings for Quality, Schedule, Cost, and Business/Management, using a scale from Very High (VH) to Very Low (VL) or Not Rated (N/R).
