NASA has quietly revealed that scientific payloads won't be prioritized for its next Mars mission through a non-public procurement document. The space agency released a pre-solicitation for the Mars Telecommunications Network spacecraft, which will provide communications relay services for missions operating through 2035. The $700 million contract, funded by recent legislation, is expected to be awarded by September 2026.

Originally known as the Mars Telecommunications Orbiter, the spacecraft was thrust into political spotlight when Senator Ted Cruz's office included specific funding in the 'One Big Beautiful Bill' legislation. While the bill seemed designed to favor Rocket Lab, sources tell Ars Technica the poorly written language has opened the competition. The pre-solicitation seeks industry feedback on objectives and requirements, but the key 24-page document remains 'controlled' and not publicly available.

The document's final ground rule states that 'SMD payload is not precluded, and schedule risk is critically important.' This language suggests NASA will penalize proposals that include scientific instruments if they pose any risk to the launch timeline. With the spacecraft launching no earlier than late 2028, it represents NASA's only major Mars mission for the remainder of the decade, yet science appears to be taking a back seat to communications reliability.
