This diagram shows the distances of the planets in our Solar System (upper row) and in the Gliese 581 system (lower row), from their respective stars (at left). The habitable zone is indicated as the blue area, showing that Gliese 581d is located inside the habitable zone around its low-mass red dwarf star
- /CSIRO Canberra Deep Space Communication Complex at Tidbinbilla, near Canberra. Over the past 37 years, the 70-metre main antenna, known as Deep Space Station 43, has supported many missions exploring our Solar System and beyond, including keeping in touch with the Apollo astronauts, providing two-way radio contact with the Mars Exploration Rovers, and deep-space missions such as the twin Voyager spacecraft and NASA's New Horizons probe to Pluto.
