## What project 621010 buys

This project develops technologies to ensure spacecraft survivability and to enhance surveillance of the space operating environment. Technology development to enhance the ability of space assets to operate effectively despite the challenges of the space environment. This includes developing radiation-hardened electronics and technologies to understand and mitigate impacts of the space environment. The focus is on characterizing and forecasting the battlespace environment for more realistic space system design, modeling, and simulation, as well as the battlespace environment's effect on space systems' performance. This includes technologies to specify and forecast the space environment for planning operations, ensure uninterrupted system performance, optimize space-based surveillance operations, and provide capability to mitigate or exploit the space environment for both offensive and defensive operations.

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
