- Mars is the fourth planet and the furthest terrestrial planet from the Sun. The reddish color of its surface is due to finely grained iron(III) oxide dust in the soil, giving it the nickname “the Red Planet”. Mars’s radius is second smallest among the planets in the Solar System at 3,389.5 km (2,106 mi). It has a surface gravity of 3.72 m/s2 (12.2 ft/s2), which is 38% of Earth’s gravity. The Martian dichotomy is visible on the surface: on average, the terrain on Mars’s northern hemisphere is flatter and lower than its southern hemisphere. Mars has a thin atmosphere made primarily of carbon dioxide and two irregularly shaped natural satellites: Phobos and Deimos.
- Curiosity (rover) (Wikipedia)
Curiosity is a car-sized Mars rover exploring Gale crater and Mount Sharp on Mars as part of NASA’s Mars Science Laboratory (MSL) mission. Curiosity was launched from Cape Canaveral (CCAFS) on November 26, 2011, at 15:02:00 UTC and landed on Aeolis Palus inside Gale crater on Mars on August 6, 2012, 05:17:57 UTC. The Bradbury Landing site was less than 2.4 km (1.5 mi) from the center of the rover’s touchdown target after a 560 million km (350 million mi) journey.
- Total Recall (1990 film) (Wikipedia)
Total Recall is a 1990 American science fiction action film directed by Paul Verhoeven, with a screenplay by Ronald Shusett, Dan O’Bannon, and Gary Goldman. The film stars Arnold Schwarzenegger, Rachel Ticotin, Sharon Stone, Ronny Cox, and Michael Ironside. Based on the 1966 short story “We Can Remember It for You Wholesale” by Philip K. Dick, Total Recall tells the story of Douglas Quaid (Schwarzenegger), a construction worker who receives an implanted memory of a fantastical adventure on Mars. He subsequently finds his adventure occurring in reality as agents of a shadow organization try to prevent him from recovering memories of his past as a Martian secret agent aiming to stop the tyrannical regime of Martian dictator Vilos Cohaagen (Cox).
- Sun (Wikipedia)
The Sun is the star at the center of the Solar System. It is a massive, hot ball of plasma, inflated and heated by energy produced by nuclear fusion reactions at its core. Part of this internal energy is emitted from its surface as light, ultraviolet, and infrared radiation, providing most of the energy for life on Earth.
- Solar System (Wikipedia)
The Solar System is the gravitationally bound system of the Sun and the objects that orbit it. The largest of such objects are the eight planets, in order from the Sun: four terrestrial planets named Mercury, Venus, Earth and Mars, two gas giants named Jupiter and Saturn, and two ice giants named Uranus and Neptune. The terrestrial planets have a definite surface and are mostly made of rock and metal. The gas giants are mostly made of hydrogen and helium, while the ice giants are mostly made of ‘volatile’ substances such as water, ammonia, and methane. In some texts, these terrestrial and giant planets are called the inner Solar System and outer Solar System planets respectively.

- Stranger in a Strange Land (Wikipedia)
Stranger in a Strange Land is a 1961 science fiction novel by American author Robert A. Heinlein. It tells the story of Valentine Michael Smith, a human who comes to Earth in early adulthood after being born on the planet Mars and raised by Martians, and explores his interaction with an eventual transformation of Terran culture.
- Jupiter (Wikipedia)
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, and slightly less than one one-thousandth the mass of the Sun. Jupiter is the third brightest natural object in the Earth’s night sky after the Moon and Venus, and it has been observed since prehistoric times. It was named after Jupiter, the chief deity of ancient Roman religion.
- Earth (Wikipedia)
Earth is the third planet from the Sun and the only place known in the universe where life has originated and found habitability. Earth is the only planet known to sustain liquid surface water, with ocean water extending over 70.8% of the planet, making it an ocean world. Most of all other water is retained in Earth’s polar regions, with large sheets of ice covering ocean and land, dwarfing Earth’s groundwater, lakes, rivers and atmospheric water. The other 29.2% of the Earth’s surface is land, consisting of continents and islands, and is widely covered by vegetation. Below the planet’s surface lies the crust, consisting of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Inside the Earth’s crust is a liquid outer core that generates the magnetosphere, deflecting most of the destructive solar winds and cosmic radiation.
