Completed TRL 2 (started at 1, targeting 2)
We propose a global, multi-spectral, high-resolution planetary surveyor supported by regular visits from a cycler satellite network to retrieve petabits of data for transit to Earth. The “courier” satellites use optical communications to receive 1-3 petabits from the surveyor at least once per year. They then travel close to earth where they can downlink the data quickly. By exploiting cycler orbits, the couriers need minimal onboard propulsion and can operate for decades as an augmentation to the Deep Space Network and a precursor to a Human Exploration logistics network.
Enables global high-resolution survey of planetary body with minimal impact to DSN, yet returns 1000x more data per year from Mars. Easily-engaged commercial sector with “data logistics.” Easily-engaged public interest with visits by couriers which could be built by companies, nations, or schools.
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 2) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
