Space Missions & Technology
Deep Space Network
NASA's ground network for communication and navigation with distant missions.
Why it matters
A spacecraft's scientific discoveries depend on returning usable information to Earth.
Specific hardware / mission infrastructure
Overview
Deep-space spacecraft carry limited power and operate across enormous distances. Large ground antennas and carefully scheduled contact periods help recover weak signals. The network also supports measurements used for navigation.
Educational reference, reviewed . This page is not a live mission-status report.
How it works
Antennas transmit commands and receive telemetry. Timing and frequency measurements of radio signals help estimate spacecraft motion and range as part of a navigation solution.
