Alpine satellite
Summary:
Alpine is equipped with bi-directional S-band command, telemetry links, and a high-speed Ka-band lunar proximity uplink and X-band downlink to Earth for low-latency real-time communications. After the primary surface mission, Alpine naturally circularize into High Circular Polar Orbits (HCPO). These orbits provide near-global coverage of the lunar surface with a focus region over the poles. For each lunar day cycle, the relays provide simultaneous visibility of Earth and lunar South Pole regions.

The Alpine Relay Satellite offers enhanced communication range, enabling missions and payload operations in lunar regions without line-of-sight to Earth.
