On March 26, 2012, National Geographic Explorer-in-Residence James Cameron succeeded in tackling his biggest challenge ever-a solo journey to Challenger Deep, the deepest known point in the ocean. Challenger Deep is 10.99 kilometers (6.83 miles) deep and is found at the southern end of the Mariana Trench near Guam. Years in the making, this feat has been      compared to landing on the moon.

Through visually stunning imagery, and in collaboration with leading space experts,  Journey to Space 3D showcases the exciting plans NASA and the space community are working on and the challenges they must overcome to carry out missions, once considered science fiction, and now science fact, such as landing astronauts on Mars. The film calls attention to the reality that the space program did not die with the end of the Shuttle Program in 2011. It is instead, vibrantly alive.

Journey To Space also gives a fitting tribute to the Space Shuttle Program and the 355 astronauts who flew on the 135 Shuttle missions. This historical chapter in the film is in the first one-third of the movie and describes how the Shuttle took many of the big steps that helped us understand how to live and operate in space. In fact, it's the lessons learned during those many steps that have enabled the future missions covered in the film. The film also gives a strong overview of the Shuttle's last major project - the launch and assembly of the International Space Station (ISS). The ISS is a joint collaboration of 15 nations and is operating 24/7 providing a true home and science lab in space like no other. ISS crews' tours of duty have averaged six months, and NASA will begin one-year duration missions starting in 2015. Researchers expect the one-year mission to yield beneficial knowledge on the medical, psychological and biomedical challenges explorers may face as they venture to an asteroid, Mars and beyond.
