WebLanding. During landing, the spacecraft switches between several antennas. Some use ultrahigh frequency (UHF) transmission, communicating with orbiting spacecraft, like the Mars Reconnaissance Orbiter (MRO), which then relay the information back to Earth. Other antennas use more powerful X-band transmissions, talking directly to Earth with simple … http://parelectronics.com/earth-moon-earth.php
