Summary

NASA is advancing its Mars Telecommunications Network (MTN) mission, a \$700 million project intended to serve as a communications relay for other spacecraft at Mars, with a planned launch in late 2028 and full operational status by the end of 2030. Initially lacking a science role, NASA has now mandated the inclusion of a small science payload, potentially comprising free-flying CubeSats, with specific requirements for weight (up to 20 kilograms), volume (55 by 55 by 45 centimeters), power (up to 60 watts), and data generation (200-1,000 megabits/day). The agency plans a rapid procurement process, with the final Request for Proposals (RFP) due May 1 and an award by September, attracting interest from companies like Blue Origin, Rocket Lab, and Lockheed Martin. This addition aligns with NASA's broader goal of integrating science into every mission, while ensuring the payload does not impact the MTN's aggressive schedule.

Key takeaway

NASA's \$700 million Mars Telecommunications Network (MTN) mission now requires proposals to include space for a small science payload. This payload, up to 20 kg and 55x55x45 cm, could be CubeSats provided by NASA, generating 200-1000 Mbps/day without impacting the 2028 launch. This opens a new, immediate opportunity for planetary science and CubeSat developers, with the final RFP due May 1.
