Rotation and Interior Structure Experiment (RISE) is a radio science experiment onboard InSight Mars lander that will use the spacecraft communication system to provide precise measurements of Mars' rotation and wobble. RISE precisely tracks the location of the lander to measure how much Mars's axis wobbles as it orbits the Sun.
Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...

Mars sky at sunset, as imaged by the Curiosity rover (February 2013; Sun simulated by artist). The seasonal lag on Mars is no more than a couple of days, [1] due to its lack of large bodies of
"Space" was conceived as a low-budget bottle episode, due to several earlier episodes having exceeded their budgets. [3] Series creator Chris Carter was inspired to write the episode after reading about news of the "face on Mars"—an instance of pareidolia wherein a mound in the Cydonia region of Mars was taken to resemble a human face.

Mars could be humanity's first step in space colonization, and new discoveries reveal answers to Mars's greatest mysteries. This special consists entirely of segments previously aired as part of the Strip the Cosmos episode "Expedition Mars" (Season 1, Episode 4), the Space's Deepest Secrets episode "Mars: The Next Frontier" (Season 4, Episode 7), and the Mars: The Secret Science episode "Is ...
A space station (or orbital station) is a spacecraft which remains in orbit and hosts humans for extended periods of time. It therefore is an artificial satellite featuring habitation facilities . The purpose of maintaining a space station varies depending on the program.
In his 1976 book The High Frontier: Human Colonies in Space Dr. Gerard O'Neill proposed the establishment of gigantic Space Islands in L 5. The inhabitants of the L5 Society should convert lunar material to huge solar power satellites. Many works of fiction, most notably the Gundam series, involve colonies at these locations.
