New Debate Over Colors: Mars Is Red Or Blue?
This week literally belongs to colors. People seem so devoted to make necessary or unnecessary distinctions between colors. Earlier we had this debate over the true color of that famous dress; Scottish singer Caitlin McNeil posted an image of the dress on Tumblr and posed a question about the color of the dress: Is this dress in blue and black or white and gold?
That image of the enigmatic dress is still viral on the Internet. Some people claim that the mystery has resolved while others are still arguing over it. But I’m not attempting to settle the debate; in fact, I’m going to tell you about another problematic debate which is over the color of Mars. TechTimes regards this “bigger problem,” because Curiosity rover has questioned the color of not a shirt or trouser but of a planet.
The planet Mars has always been recognized as red in color (even called as the Red Planet.) The rationale given for terming Mars Red Planet is the evidence of the presence of iron oxide on its surface. However, Curiosity rover has sent an image in which it shows that though the color of Mars surface is red, but after drilling a hole, the blue or gray-colored soil can be seen.
Drilling activities on Mars have been initiated by the Curiosity rover. The purpose of this drilling project is the collection of samples for detailed analysis by the rover’s on-board lab. NASA has released a picture of a drilling site where a hole has been drilled by rover. The drilling was done on Martian rock called Telegraph Peak.
The color of the drilled soil actually seems to be blue or gray in color, which validates rover’s claim (remember: I’m not a planet expert). The experts are observing the issue with a different perspective. They say that the difference in the color of the upper surface and lower soil is due to the different matter present on/under the surface.
They suggest that the reason of the red surface of Mars is due to the presence of a layer of dust, over the entire planet. Because of the absence of this soil under it, the color is different.
Curiosity rover’s mission is continued on Mars. They may make various other discoveries challenging the conventional beliefs.
