Mars 101 | National Geographic

To the ancient Romans, the planet Mars was symbolic of blood and war. But to many people today, the red planet may hold the key for a bright, new future for humanity.

The story of Mars began about 4.5 billion years ago, when gas and dust swirled together to form the fourth planet from the Sun.

Mars is the second-smallest planet in the solar system, with a diameter just shy of the width of Africa. In fact, its entire surface area is similar to that of all of Earth’s continents combined. Much like its terrestrial cousin, Mars is dense and has a rocky composition. At the center of the planet is a core made of iron, nickel, and sulfur, which may have created a protective magnetic field during Mars’s earlier years.

Enveloping the core is a rocky mantle made of silicate minerals and a crust rich in iron. These iron minerals react with the trace amounts of oxygen in Mars’s atmosphere and rusts, giving the planet its signature reddish hue. While its blood-like appearance inspired the ancient Romans to name Mars after their god of war, the planet’s rusty color could be considered symbolic of the planet’s prime days long past.

Today, Mars is dry, desolate, and cold (with temperatures dropping as low as -225 degrees Fahrenheit). But billions of years ago, the planet was much warmer, more geologically active, and had a watery surface. While its blood-like appearance inspired the ancient Romans to name Mars after their god of war, the planet’s rusty color could be considered symbolic of the planet’s prime days long past.

Lake-beds and river valleys snake along the face of Mars, indicating that liquid water was, for a time, present. Volcanoes, such as Olympus Mons, the largest volcano in the solar system at three times the height of Mt. Everest, once erupted with lava. But by about 50 million years ago, soon after Earth’s dinosaurs died out, Mars’s volcanoes also went extinct. Water on the red planet still exists today, but mostly in the form of polar ice caps.

Because of factors such as the presence of water, some scientists believe life may have existed on the red planet — and may exist again.

Since the 1960’s, space programs from around the world have launched missions to Mars in attempts to understand the planet’s past, present, and potential for sustaining life.

Life on another planet may well be out of reach for the near future.

But if any planet could give us hope, Mars may hold the key to the survival of humanity.

How to spot the Planets in the sky with naked eye

With naked eye we can see 5 Planets –

  • Mercury
  • Venus
  • Mars
  • Jupiter
  • Saturn

Right now, from western part of India, near to the latitude – Tropic of Cancer – we can spot 4 of this planet between 6:30 PM IST to 7:30 PM IST here or there.

Last one week I am tracking the position and enjoying the view of this planets in the sky with different shades behind, as the sun goes below the horizon.

Venus is the brightest star, that usually appears first in the west sky. It is almost going down and will be in sky for the next 2 hours. It is so bright that it looks like a light bulb or a street light far off, as the darkness increases.

Right beside Venus a little higher in the sky towards a little bit left is the Jupiter. It is bright as well and in the last 6 months it has been in the sky. Earlier it used to rise, right after the Sun-set, now it stays in the sky 3-4 hours after the sunset.

Once you spot this 2 planets, you got to move towards your left and keep going on until you see equally bright star, which looks more or less like Venus, but a little bit of red shade, at least I feel it, since I keep looking at it knowing it is Mars, you might not feel so, but the brightness is noticeable and you will figure it out.

Move a little to the right again and the star that is like a little dot is Saturn, without any rays coming out, it will be difficult to spot on your own for the first time, but if you keep looking in the sky at dusk, you might see it before the other similarly sized stars come up in sky and then you get confused.

For ease of spotting it in the first week, I would suggest to use – Skyview App which works perfectly fine as you get a view of the sky from your camera and then the position of planets and stars shown on your screen overlay on the camera view. In few hours, you will get hold of the app and you will know the time of rise for Sun, Moon and other major planets, you can know the trajectory or the position of them and then you know the constellations and how to point. Basically you get the hold of sky.

Keep looking for few days and then you would know where the Planets are without the help of this App. At any point if you feel confused from a new location or at a different time if you look in sky, you can use this App.

I have been enjoying this experience a lot and would continue to sky gaze in the coming weeks.

Share you experience of sky-gazing or pick a moment when you enjoyed the most.

Yesterday I saw the perfect crescent and it was a wonderful experience altogether, tracking it for 3 hours.
