+====== Mars ======
 ==== Blue sunsets ====
-Sunsets and sunrises on mars are blue due to the large number of dust particles in the atmosphere. Blue light penetrates this type of atmosphere more effectively compared to the longer wavelengths of yellow and red light. For the same reason, during the day the sky appears orange due to the scattering of yellow and red light. [([[https://solarsystem.nasa.gov/news/925/what-does-a-sunrise-sunset-look-like-on-mars/]])]

 ==== Mars name ====
-The fourth planet of the solar system is named after the Roman god of war, Mars,[([[https://en.wikipedia.org/wiki/Mars_(mythology)]])] because of its red hue visible even with the naked eye. [([[https://en.wikipedia.org/wiki/Mars#Names]])]

 ==== Moons of Mars ====
-Mars has two small moons, Phobos (22.2 km, 13.8 mi) and Deimos (12.6 km, 7.8 mi) [(https://en.wikipedia.org/wiki/Moons_of_Mars)].

 ==== 687 Earth days ====
-The length of the year on Earth is 365.25 days. The year on Mars is almost twice as long! It lasts for 687 Earth days.[(https://mars.nasa.gov/all-about-mars/facts/)].

 ==== Eight active missions ====
-As of December 2020, there are eight missions from around the world actively orbiting Mars or exploring its surface. The missions are from the U.S., European Union, Russia, and India.[(https://www.nationalgeographic.com/science/space/solar-system/mars/)].

 ==== Curiosity rover ====
-On Jan 12, 2021, NASA's Curiosity rover passed 3.000 Martian days of work on surface of the Mars. It managed to travel over 23km on (as of Jul 2020). It's powered by nuclear battery, radioisotope thermoelectric generator (RTG), producing energy from decay of 11 lb (4.8 kg) plutonium-238 dioxide[(https://en.wikipedia.org/wiki/Curiosity_%28rover%29)].

 ==== Opportunity rover ====
-Is a robotic rover that was exploring mars surface for 15 years, between 2004 and 2018. It's mission was planned for 90 sols (Martian days), but managed to work 5,352 sols (5,498 earth days). Opportunity drive 45.16 km, made over 224,000 photographs, made many important findings, i.e. evidences of salty water deep enough to alter rocks[(https://mars.nasa.gov/mer/highlights/opportunity-spirit-rovers-mission-overview/)].
