Communication system

Telemetry, Tracking & Command (TT&C)

The end-to-end function every mission depends on: downlinking telemetry (spacecraft health and science), measuring the signal for tracking and navigation, and uplinking commands. The deep-space and near-Earth networks exist to provide TT&C.

Visual knowledge graph

Relationships, not isolated facts

This viewport is generated from the Asteria knowledge graph. Science, culture, and interpretive links remain separated by domain so visual context never changes the evidentiary meaning of a relation.

Curated next objects

signal band

S-band

A lower-frequency microwave band long used for spacecraft command and low-rate telemetry, and for near-Earth links. Robust and less affected by weather than higher bands, but limited in data rate.

signal band

X-band

The workhorse band of deep-space communication and radiometric navigation. Most interplanetary missions send their science data and are tracked on X-band, which balances data rate against antenna size and weather losses.

tracking network

Deep Space Network (DSN)

NASA's international array of giant radio antennas — at Goldstone (California), Madrid, and Canberra — that communicates with interplanetary spacecraft and distant satellites, spaced around the globe for continuous coverage.

tracking station

Canberra Deep Space Communication Complex

The southern-hemisphere complex of NASA's Deep Space Network, in Australia. Its 70 m antenna (DSS-43) is the only one able to command Voyager 2 on its southward interstellar trajectory.

tracking network

Commercial Deep-Space Services

A growing set of commercial providers — such as KSAT, SSC, and Goonhilly — that offer deep-space and near-Earth ground-station support on a service basis, augmenting the government networks as mission traffic grows. NASA's Near Space Network increasingly buys commercial services alongside its own antennas.

tracking station

Goldstone Deep Space Communications Complex

The US complex of NASA's Deep Space Network, in California's Mojave Desert. Its 70 m antenna (DSS-14, the 'Mars' dish) and a cluster of 34 m beam-waveguide antennas track spacecraft across the Solar System.
