Sure
The Mars Express mission is an orbiter / lander combination. The lander, Beagle 2, talks to the orbiter, which relays the information to Earth. There was talk about enabling Beagle 2 to talk to Mars Oddysey as well. I haven't heard anything lately about that, but I assume they are doing this.
The orbiter, by the way, includes a fine suite of instruments, including an imaging RADAR that will be able to peek beneath the surface of Mars.
