Can Jupiter unlock the secrets of Earth’s formation? How did a team engineer a spacecraft to endure a toxic mix of radiation and gaseous turbulence? After a five-year journey, the moment of truth is finally here. Jupiter: Close Encounter delivers a comprehensive, hour-long look at the unprecedented, amazing, and utterly extreme journey of NASA’s heavily armoured Juno Spacecraft on an odyssey to the largest planet in the solar system. Anchored by DAILY PLANET Co-Host Dr. Dan Riskin from the NASA Jet Propulsion Laboratory (JPL) in Pasadena, California, Jupiter: Close Encounter follows NASA’s Juno Spacecraft mission as it attempts to enter a “polar orbit” around the king of the the solar system for the first time ever on July 4. The landmark mission will study the planet’s spectacular auroras, seek the inner-most core, and wade into Jupiter’s Great Red Spot. The gripping one-hour special introduces viewers to the dedicated and incredible team behind the high stakes-mission – scientists determined to provide new answers to the mystery of the solar system, Earth, and life itself.
Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system. The Kuiper Belt is a donut shape aligned with the plane of the solar system; the scattered disk is more eccentric and is the source of short period comets; and the Oort Cloud which surrounds the solar system out to great distances is the source of long-period comets. These bodies all probably formed closer into the Sun, and got flung out to the solar system’s suburbs by gravitational interactions with the outer planets.
In the 1950s and early '60s, a small band of high-altitude pioneers exposed themselves to the extreme forces of the space age long before NASA's acclaimed Mercury 7 would make headlines. Though largely forgotten today, balloonists were the first to venture into the frozen near-vacuum on the edge of our world, exploring the very limits of human physiology and human ingenuity in this lethal realm.

Today Phil helps keep you from ticking off an astronomer in your life by making sure you know the difference between a meteor, meteorite, and meteoroid. When the Earth plows through the stream emitted by a comet we get a meteor shower. Meteors burn up about 100 km above the Earth, but some survive to hit the ground. Most of these meteorites are rocky, some are metallic, and a few are a mix of the two. Very big meteorites can be a very big problem, but there are plans in the works to prevent us from going the way of the dinosaurs.
The United States and China are considering launching manned missions to Mars -- in 25 years. But Netherlands-based Mars One has a bold plan to land humans on Mars in 2027. Is the mission fuelled by wishful thinking and unproven science -- or will private explorations get us there?
Astronaut Mike Massimino reveals the mysterious secrets of Saturn and its rings; using the latest science from the Cassini mission, he explores the planet's giant icy geysers, powerful hurricanes, and moon that may be hiding extraterrestrial life.
The first episode of Space Voyages looks at the Mars Curiosity Rover - an incredible 21st century machine. And it would never have been possible without the accomplishments of early NASA astronauts and engineers. Everything was new – rocket science, astronaut survival – even simply steering in space! This is the story of how both humans and robots laid the foundations for space exploration that continues today.
