AMENDMENT 01: The Abstract Due Date is extended to December 4, 2025, by 12:00 PM ET.

The goal of the TBD2 program is to enable continuous space-based detection and tracking of objects in cislunar space on relevant timelines. This effort will increase the safety of cislunar commercial and civilian traffic for the benefit of all nations and enable a sustainable space ecosystem. To accomplish this, TBD2 seeks to advance the state of the art for signal processing algorithms so that when combined with commercial off-the-shelf (COTS) or quasi-COTS optical sensors and/or focal plane arrays (FPAs), they can a) detect and track faint objects at gigameter (Gm) distances b) operate using available onboard processing capabilities, and c) do so on relevant timelines (within hours).
