Draft RFP - Mars Telecommunications Network (MTN)

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.

Form / Attachment / Pricing Sheet

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).
• Section 6: Focuses on Contract Value, Expenditures to Date, Annual Contract Value, cost overruns, and overall contract performance rating.

This questionnaire is crucial for bidders as it outlines the specific criteria and areas the government will use to evaluate their past performance. Understanding these evaluation factors helps bidders prepare their own past performance narratives and identify relevant past contracts to submit for evaluation. The detailed breakdown of SOW elements and performance metrics provides insight into what aspects of performance are most valued by the agency.
