Mars is the fourth planet from the Sun in the Solar System. Named after the Roman god of war, Mars, it is often described as the "Red Planet" as the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the highest known mountain within the Solar System, and of Valles Marineris, the largest canyon. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature.

Until the first successful flyby of Mars occurred in 1965, by Mariner 4, many speculated about the presence of liquid water on the planet's surface. This was based on observed periodic variations in light and dark patches, particularly in the polar latitudes, which appeared to be seas and continents; long, dark striations were interpreted by some as irrigation channels for liquid water. These straight line features were later explained as optical illusions, though geological evidence gathered by unmanned missions suggest that Mars once had large-scale water coverage on its surface. In 2005, radar data revealed the presence of large quantities of water ice at the poles, and at mid-latitudes. The Mars rover Spirit sampled chemical compounds containing water molecules in March 2007. The Phoenix lander directly sampled water ice in shallow Martian soil on July 31, 2008.

Willard Christopher "Will" Smith, Jr. (born September 25, 1968), also known by his stage name The Fresh Prince, is an American actor, producer, and rapper. He has enjoyed success in television, film and music. In April 2007, Newsweek called him the most powerful actor in Hollywood. Smith has been nominated for four Golden Globe Awards, two Academy Awards, and has won multiple Grammy Awards.

In the late 1980s, Smith achieved modest fame as a rapper under the name The Fresh Prince. In 1990, his popularity increased dramatically when he starred in the popular television series The Fresh Prince of Bel-Air. The show ran for nearly six years (1990–1996) on NBC and has been syndicated consistently on various networks since then. In the mid-1990s, Smith moved from television to film, and ultimately starred in numerous blockbuster films. He is the only actor to have eight consecutive films gross over $100 million in the domestic box office and the only one to have eight consecutive films in which he starred open at #1 spot in the domestic box office tally.
