Tribute to the spirit of our continuing exploration of the solar system and the universe beyond. Never before possible, we board a satellite in space to look back upon the shuttle as it orbits the Earth. We are part of the crew, working alongside the astronauts as they deploy and repair the Hubble Space Telescope. We travel millions of miles beyond Earth to soar above the remarkable contours of Venus and Mars. Finally, we find astonishing proof of new planets, and with them the possibility of other life, forming around distant stars. 40 minutes.
