Roving Mars is an IMAX documentary film about the development, launch, and operation of the Mars Exploration Rovers, Spirit and Opportunity.
 The film uses few actual photographs from Mars, opting to use computer generated animation based on the photographs and data from the rovers and other Mars probes.
 The film has been released on Blu-ray disc by distributor Disney.
Adam Diedrich Steltzner (born 1963) is an American NASA engineer who works for the Jet Propulsion Laboratory (JPL).
 He worked on several flight projects including Galileo, Cassini, Mars Pathfinder, Mars Exploration Rovers (MER).
 He was the lead engineer of the Mars Science Laboratory's EDL phase (Entry, Descent and Landing), and helped design, build and test the sky crane landing system.
Jacob (Richard) Matijevic, also known as "Jake" Matijevic, (3 November 1947 – 20 August 2012) was an American NASA engineer of Croatian origin who worked on Mars Exploration Rovers.
 Dr. Matijevic was involved in developing the ""Sojourner"", ""Spirit"", ""Opportunity"" and ""Curiosity"" rovers.
 For his contributions to the rover projects, NASA named several landmarks on the planet Mars (including ""Matijevic Hill"" and ""Jake Matijevic"" rock) after him.
Scott Maxwell is an American engineer and former lead mars rover planner driving the Mars Exploration Rovers (MER) Spirit and Opportunity at the Jet Propulsion Laboratory in Pasadena, California.
2001 Mars Odyssey is a robotic spacecraft orbiting the planet Mars.
 The project was developed by NASA, and contracted out to Lockheed Martin, with an expected cost for the entire mission of US$297 million.
 Its mission is to use spectrometers and a thermal imager to detect evidence of past or present water and ice, as well as study the planet's geology and radiation environment.
 It is hoped that the data "Odyssey" obtains will help answer the question of whether life has ever existed on Mars and create a risk-assessment of the radiation future astronauts on Mars might experience.
 It also acts as a relay for communications between the Mars Exploration Rovers, Mars Science Laboratory, and previously the Phoenix lander to Earth.
 The mission was named as a tribute to Arthur C. Clarke, evoking the name of "".
Fun and Fancy Free is a 1947 American live-action animated musical fantasy comedy package film produced by Walt Disney and released on September 27, 1947 by RKO Radio Pictures.
 It is the 9th Disney animated feature film and the fourth of the package films the studio produced in the 1940s in order to save money during World War II.
 The Disney package films of the late 1940s helped finance "Cinderella", and subsequent others, such as "Alice in Wonderland" and "Peter Pan".
Melody Time (working title All in Fun) is a 1948 American live-action animated film and the 10th theatrically released animated feature produced by Walt Disney.
 It was released to theatres by RKO Radio Pictures on May 27, 1948.
 Made up of several sequences set to popular music and folk music, the film is, like "Make Mine Music" before it, the popular music version of "Fantasia" (an ambitious film that proved to be a commercial disappointment upon its original theatrical release).
 "Melody Time", while not meeting the artistic accomplishments of "Fantasia", was mildly successful.
 It is the fifth Disney package film following "Saludos Amigos", "The Three Caballeros", "Make Mine Music", and "Fun and Fancy Free".
Joy A. Crisp is a planetary geologist specializing in Mars geology.
 She is noted for her work on NASA missions to Mars, including the Mars Exploration Rovers and Mars Science Laboratory.
Mars Reconnaissance Orbiter (MRO) is a multipurpose spacecraft designed to conduct reconnaissance and exploration of Mars from orbit.
 The US$ spacecraft was built by Lockheed Martin under the supervision of the Jet Propulsion Laboratory (JPL).
 The mission is managed by the California Institute of Technology, at the JPL, in Pasadena, California, for the NASA Science Mission Directorate, Washington, D.C.
 It was launched August 12, 2005, and attained Martian orbit on March 10, 2006.
 In November 2006, after five months of aerobraking, it entered its final science orbit and began its primary science phase.
 As MRO entered orbit, it joined five other active spacecraft that were either in orbit or on the planet's surface: "Mars Global Surveyor", "Mars Express", "2001 Mars Odyssey", and the two Mars Exploration Rovers ("Spirit" and "Opportunity"); at the time, this set a record for the most operational spacecraft in the immediate vicinity of Mars.
 "Mars Global Surveyor" and the "Spirit" rover have since ceased to function; the remainder remain operational as of September 2016.
Kobie Boykins is a senior mechanical engineer at NASA's Jet Propulsion Laboratory in Pasadena, California.
 In 2013, he was awarded the NASA Exceptional Achievement Medal.
 He designed the solar array systems for the Mars exploration rovers "Spirit" and "Opportunity", and designed the actuators on the Mars rover "Curiosity".
 He is currently the supervisor of the mobility and remote sensing teams for "Curiosity".
 In 2003, he was part of NASA's M-Team, which lectured nationally to students regarding careers in science, technology, engineering, and mathematics.
 He lectures internationally for National Geographic regarding exploration on Mars.
