Martian Sunset…But Not As You Know It!
“Welcome to Mars! The home of beautiful red sunsets and romantic pink-hued views of Earth in an exotic Martian dusk…lazy summer evenings in Gale Crater relaxing in your rose-tinted deck chairs on the red Sands of Mars, sun hats glowing softly in cooling evening sun… watching the first glimmers of rising stars in the interstellar regions between the neighbouring gas giant Jupiter red oxide beaches of Mars… the distant howls of the Black wolves of Mars shimmering golden-red shades in the setting sun….all the ingredients of the perfect intergalactic holiday ”
But wait! Action replay!! This web page no longer exists! NASA’s Mars rover Curiosity has just blown the whole intergalactic holiday guide to Mars straight out of the water!
“Welcome to Mars! The home of serene blue-hued sunsets and softly blue-tinged skies!! … What! What! Stunning blue sunsets on Mars!!! the distant howls of the Black wolves of Mars shimmering cool blue shades of azure light in the setting sun on the towering foothills of Mount Sharp….all the ingredients of the perfect intergalactic holiday …” REALLY?!!
Apparently so. Curiosity doesn’t tell ‘porkies’ and along with the images it kindly sent back to Earth it also saw fit to send a tweet too, so it must be true!
@Curiosity Rover “Let us go you and I…”
But WHY??!!! Are Curiosity and NASA finally losing it? Blue skies on Mars my Icewolfie paw!!! Hmm…well according to Mark Lemmon of Texas A&M University – the Curiosity science-team member who planned the observations, maybe not…the theory goes like this….
“When the blue light scatters off the dust, it stays closer to the direction of the Sun than light of other colours does. The rest of the sky is yellow to orange, as yellow and red light scatter all over the sky instead of being absorbed or staying close to the Sun.
Just as colours are made more dramatic in sunsets on Earth, Martian sunsets make the blue near the sun’s part of the sky much more prominent, while normal daylight makes the rusty colour of the dust more prominent.”
So! What should have looked like this……
….apparently looks like this! Welll…maybe this is slightly exaggerated but hey! You get the general picture yes? ;}
The Curiosity rover gathered enough evidence from around where it landed in Gale Crater (August 2012) to give firm grounds for believing that billions of years in Mars’ past a lake and stream system existed with the potential for habitation.
Today, 3 years later in 2015, Curiosity is hard at work in the centre of Gale Crater checking out Mt. Sharp which soars 3.4 miles (5.5 km) into the alien skies of Mars. Its numerous layers of rock (Mt Sharp that is not Curiosity ) contain the key to historic environmental situation variants that have occurred on Mars across the centuries. The purpose of Curiosity’s mission here is to discover how Mars developed from a comparatively temperate and moist world somewhere back in the dim and distant past to the cold, arid desert wilderness world it has transformed into in the present times.
Needless to say mission scientists are yet to discover what any self-respecting intergalactic tourist to the Red Planet is fully aware of, from long nights spent lounging in the BLUE Martian sunsets in their favourite deck chair – the presence of “The Black Wolves of Mars,” howling lyrically long into the alien nights!
