NASA is on a mission to send humans to Mars within just 15 years, but to reach this next frontier of space exploration, experts must discover new technology and cutting-edge science that protects astronauts from the Red Planet's deadliest killers.

The Rosetta mission was a ground-breaking expedition to land on a comet for the first time, the 67P/Churyumov-Gerasimenko comet. The Rosetta mission tries to answer our most fundamental questions and to change our understanding of the cosmos forever. Special access reveals what this cutting-edge journey discovered and how these mysterious objects helped create life on Earth.

Principles of generosity and prosperity inform the selection of the last two crew members: Christopher Sembroski, a former member of the U.S. Air Force who served in Iraq and now works as a Lockheed Martin engineer, and Sian Proctor, a professor of geosciences and two-time NASA astronaut candidate. Excitement for the flight ramps up, but anxiety lingers.

The digital possibilities of social control in China have led to an unprecedented level of state surveillance. Through self-censorship or spying on neighbors, surveillance covers not only those perceived as a threat by the government, but increasingly and ever more totally the ordinary citizen: whether buying flowers, taking your child to school, or taking out the trash at night. Big Data and digital technologies are already being used as weapons to curtail freedoms. Step by step, the social and political behavior of the Chinese is changing.
The documentary explores, in intimate detail, digital social control in China by following the experiences of two families and a journalist. Film-maker Jialing Zhang gives an exclusive and previously impossible intimate insight into the interior of China and tells a deeply disturbing story of how the state uses technology to control its citizens as well as propaganda to convince its people to trust it. She tells a deeply disturbing story about technology, (self-) censorship and abuse of power.

Science may soon make the dream of traveling to Mars a reality, but how will we live once we get there? How will we manage our basic human needs of food, water, and shelter on a planet known for its barren surface conditions, high radiation levels, and toxic dirt?

New discoveries have rewritten the history of our solar system, revealing a complex and violent story that begins with the birth of our Sun from the debris of a massive galactic collision, to its eventual fate as a lone zombie star.
It is a dramatic history of elegant beauty and extreme violence. The inner solar system was like a congested highway. Planets crossing lanes, frequent collisions. There were a lot of planets that could have made it but didn't, and we just happen to be one of the lucky ones that did. The players in our solar system's story are more tangled up than we ever imagined. Without all of these things interplaying, the Earth wouldn't have the stable environment that we have today, and life wouldn't be able to exist.
