When the rover speaks directly to Earth (from the surface of Mars), it sends messages via its high-gain antenna (HGA). The high-gain antenna can send a “beam” of information in a specific direction and it is steerable, so the antenna can move to point itself directly to any antenna on Earth.
How long does it take to get a picture from Mars back to Earth?
Light travels through vacuum at speed of 300,000 kilometer/second. 1 AU=149000000 kilometers. so aproximately 12 minutes at this distance.
