Many fascinating Facts About Mars – The Red Planet
Mars is the second largest planet after mercury in the solar system. And this is fourth planet from the sun.
SUNSETS ON MARS ARE BLUE
Is also known as the ‘Red Planet’ because it has a high iron oxide content which makes it appear reddish.
Mars has a thick atmosphere.
When we equate Mars ‘ density with that of the Earth’s, we’d find it’s 100 times less dense than Earth.
Mars has low air pressure on its surface which is why liquid water on its surface can not survive for long.
Mars takes twice the long for Earth to complete a complete revolution around the sun.
MONS OLYMPUS ‘TALLEST MOUNTAIN IN THE SOLAR SYSTEM’ IS ON MARS
The month of March’s name also comes from Mars.
Since more than four decades now, Mars is being explored, since it is considered a suitable location for human life. And the water signals on the mars have maintained the illusion that human life on this red planet will exist.
Several Hollywood movies were made with Mars as their theme including Flight to March 1951, The Angry Red Planet 1959, and the popular John Carter 2012 and many more.
Owing to its reddish color, Mars can be seen with the naked eye from the earth’s surface at night time. The planet’s apparent size and brightness differ based upon the planet’s proximity to the Moon.
Worm-like creatures have recently been found by NASA JPL’s Mars orbiter on the surface of Mars. Over the past 11 years, the spacecraft has been circling Mars.
These days Mars is in the news a lot, with the successful landing of robot rover Curiosity on Red Planet Mars.
People have long been fascinated by Mars and for decades the thought of sending humans to the planet was a focus of science fiction and science exploration. Part of the attraction is that scientists believe Mars ‘ atmosphere could have been warm and humid 3.5 billion years ago, and may have sustained life.
Facts About Mars
- Colour: The Planet is named for its iron-rich dust that gives the landscape a rusty-red hue.
- Diet planet: the gravity of Mars is 38 per cent of that of Earth. So if you were weighing 60 pounds here, you would weigh about 23 pounds there.
- Climate change: Mars is a warm 80 degrees Fahrenheit at the equator but the temperature at its poles will fall below zero to 199 degrees.
- In the air: The atmosphere of Mars is mostly carbon dioxide with traces of nitrogen and argon. The atmosphere on Earth is a mixture of nitrogen, oxygen, and other gases.
- Longer days: On Mars, a Martian day is about 40 minutes longer than a day.
MORE FACTS ABOUT MARS
A MARTIAN YEAR LASTS JUST Over TWO EARTH YEARS
It takes the Red Planet 687 Earth days to start out around the Sun. A day in Mars called a sol lasts 24.6 hours, an inconvenience to astronaut circadian cycles (but not as extreme as a day on Venus that lasts 5832 hours).
IT’S NOT AS HOT AS IT MIGHT LOOK
Mars looks desert – hot New Mexico with the hazy sky, red due to its iron oxide soil but is actually very cold, with a blistering hot sol being 70’F, and a cold sun a brisk-225’F. Its storms of dust can be huge; in 2018, one storm grew so big that it engulfed the whole world for more than a month. (The picture above depicts a similarly large storm of dust.)
MARS IS MUCH SMALLER THAN EARTH
Relative to Earth, Mars is a tiny Styrofoam sphere, just over half of our diameter and one-tenth of our weight. For potential colonists the gravity would be an utter nightmare, at.38 that of their home world. (That means a person weighing 100 pounds here on Mars will only weigh 38 pounds.)
AND The ATMOSPHERE IS MOSTLY CARBON DIOXIDE
You won’t want to catch a breath of fresh air on Mars unless you want to suffocate: the atmosphere is 95.32 per cent carbon dioxide, with a slight amount of nitrogen and argon mixed into it. (Earth’s atmosphere, on the other hand, is mainly nitrogen and oxygen.) If you attempt to take that single, futile breath, your eyeballs ‘ blood, your mouth’s saliva, and your lungs ‘ water will evaporate instantly. You won’t die instantly but you’re definitely going to want to.
IT HAS TWO SIDED, BOTH WITH BETTER NAMES THAN OURS
They’re named Phobos and Deimos, respectively, which translate to Fear and Dread. They are shaped like potatoes and don’t fill the evening sky exactly: standing on the Martian surface, Phobos appears to be around one-third of the size of Earth’s moon; Deimos looks like a bright star.
Although they can, potential human Martians will have to appreciate Phobos. Mars ‘ tidal forces are ripping Phobos apart; the large potato must disintegrate within 50 million years.
Meanwhile, Phobos is one of NASA’s stepping stones planning to embark on its mission to Mars. Every part of the Red Planet’s human exploration is straightforward, and before we land on Mars, it’s much easier to land on Phobos, do some recognition, then take off and go home. As a bonus, astronauts will carry along equipment required for eventual Martian settlement on their trip to Phobos, making the ride even smoother for the next astronauts. What are the highlights of Mars
MARS IS HOME TO TALLEST MOUNTAIN IN THE SOLAR SYSTEM
Mount Everest, the highest peak on Earth, is 29,029 feet tall. Olympus Mons on Mars has an altitude of over 72,000 feet, making it by far the highest peak on any planet in the solar system.
Olympus Mons is not the only extraordinary feature of Mars: Mountaineers may want to also check out NASA’s trail map to hike the popular Face on Mars. If the canyons are more your style, visit Valles Marineris. It is the size of North America, and four miles deep at its heart. (Only the Earth’s Atlantic Ocean is deeper in the solar system.) Once the Earth’s ice caps stop melting, you can still visit those on Mars. (You can easily see them if you have a telescope; they are the most defining features of the earth visible from your backyard.)
THE IDEA OF MARTIANS GOES BACK OVER A CENTURY
That’s partly because of popular literature (War of the Worlds, H.G. Wells ‘ novel of 1897, sees a Martian invasion force invade England) and partly because of Percival Lowell, the renowned astronomer who wrote prolifically about the networks he felt he was seeing through his telescope, and why they could be important for the Martian survival (Mars dried up.) Some facts on Mars.
While these claims can be easily discounted today, at the time Lowell not only popularized space exploration like few others, but left behind the Lowell Observatory in Flagstaff, Arizona, one of America’s oldest observatories and the location where Clyde Tombaugh discovered Pluto.
IF THERE ARE MARTIANS, THEY ARE MICROBES
Scientists are working diligently today to discover Mars ‘ complicated geological past, to decide whether or not life exists there today. “We think from 3.5 to 3.8 billion years ago, Mars was most conducive to life globally,” Runyon tells Mental Floss. “In the geological past of Mars, this is the end of the Noachian and towards the beginning of the Hesperian epochs.” Maybe a hemispheric ocean once existed on Mars. The earth would later have alternated between being wet and dry, with an ocean giving way to vast lakes of craters. There is decent chance of survival where there’s water. These Are Some Facts About Mars
“If we discover life on Mars either extinct or present that’s very fascinating,” says Runyon, “but more fascinating than that is if this existence originated spontaneously on Mars, separate from Earth.” It’s possible that meteorite impacts on Earth hurled existence-bearing rocks into space and ultimately to the Martian surface: “A second life appearance on Mars is not just a geological problem. That is a biogeochemical problem. We know Mars is habitable, but we didn’t address the question of whether or not it had life.
NASA SPENDS A LOT OF TIME OUT THERE
Mars hasn’t harmed missions in recent years, but scientists are now talking of a desert exploration beyond 2020. But this does not mean we humans have no eyes on the world. The Mars Reconnaissance Orbiter, which photographs and scans the earth, is currently in orbit around the planet; MAVEN, which studies its atmosphere; Mars Express, the first Mars mission of the European Space Agency; MOM, the Indian Space Research Organization’s first Mars flight; ESA’s ExoMars Trace Gas Orbiter, which searches for methane in the Martian atmosphere; and Odyssey, which studies methane in the Martian atmosphere
Curiosity and Potential are both NASA missions rolling around on the Martian surface that research Martian geology. Though the Russians and Europeans have tried hard to do so, NASA is the only space agency to successfully land spacecraft (seven times) on the Martian surface.
The InSight spacecraft will land on Mars in November 2018, where it’ll research the interior of the earth. NASA will land the Mars 2020 rover by 2020; where Mars ‘ Curiosity studies for signs of habitability, Mars 2020 will search for people.
“It will collect samples that eventually will be brought back to Earth,” Runyon says. “The three landing sites chosen for March 2020 are Northeast Syrtis, Jezero Crater, and Gusev Crater’s Columbia Hills, where the dead Spirit rover is currently located. Every one of these sites is a Noachian-Hesperian boundary-dating, hydrothermal setting. They are some of the most ideal locations to search for past Martian life signs, and they will help answer the question of whether life on Mars had a second genesis.
MARS IS Evolving, BUT NOBODY KNOWS WHY”
Most people don’t understand how involved Mars is, “Mental Floss tells Harrison. “Other planets are not just those dead worlds that are being frozen outside of our own in time. Apparently things are happening there right now. “Imagery from the Mars Reconnaissance Orbiter’s HiRISE and Context Camera instruments showed such activities as avalanches, sand dune collapse, and frequent slope lineae (Martian saltwater flowing). Those are some of the mars truth. Facts About Mars.
It is pushing things but it’s not always clear why. “There’s a lot of stuff that was washed away,” Harrison says. “We have whole planetary regions that look like they’ve been fully buried and then exhumed. And that is a lot of things. The real question is, where did all of this go? And what phase washed all of this away?” Curiosity may help address the query, but in order to fully understand the processes and history of the Sun’s fourth rock, we’ll need to send geologists in space suits. “You can not replace a rover with human intuition.”
“Seeing an image on your screen is not the same as standing there and looking around the room, stratigraphic columns, picking up the rocks and moving them, hammering stuff. So if humans land on the planet, the contrast between what we learned about Mars from the Viking and Mars Global Surveyor and then the Mars Global Surveyor – Mars Reconnaissance Orbiter revolution would be sort of like that. Our view of what we think has happened on Mars will change entirely, and we will find out that much of what we thought we knew was wrong.
