Where did the final assembly, integration, and testing (AIT) of the entire NISAR satellite structure occur?

Answer

Bengaluru, India.

The complex engineering phase involving the final assembly, integration, and testing (AIT) of all the distinct components provided by both partner agencies took place in Bengaluru, India. This location is significant because it signifies that the core hardware—including NASA's L-band instrument and spacecraft bus alongside ISRO's S-band instrument—was brought together at an ISRO facility for final verification and readiness checks before the launch sequence began. This successful integration process in an ISRO facility demonstrates a high degree of technical trust and alignment between the teams, as they managed the convergence of complex hardware sourced internationally.
