What specific antenna does a Mars rover typically use for the local uplink to a passing orbiter?

Answer

UHF antenna

The Mars assets utilize specialized communication hardware tailored for the orbital handover process. Specifically, for the local uplink transmission between the rover on the Martian surface and an orbiter passing overhead, the rover typically employs its UHF (Ultra High Frequency) antenna. This frequency band is highly advantageous for short-range communication links, allowing for high-data-rate bursts over short distances. This contrasts sharply with the complex requirements of sending large data packets millions of miles directly to Earth. The UHF connection functions as a quick, efficient transfer mechanism to offload stored scientific data before the orbital window closes.
