NASA’s Perseverance sends first ever colored pictures of alien Martian surface

It’s already 4 days since the touch down of NASA’s Perseverance rover and yet there has been a lot of curiosity flying around. Why is this touch down so special for humans? The answer to this is very simple, though we as humans have sent many rovers on alien planets. One such known is curiosity which is already present on the Martian surface. But the data which curiosity sends is coded data, which means the scientist had to de-code it to extract information.

This is what makes Perseverance unique, it has 19 cameras situated in and around the body of this rover. Secondly, it uses the technology which is used on earth to transmit data from mars to earth. There’s a satellite revolving around the mars, which acts as a transmitter between the two worlds. 

Talking about recent pics shared by NASA after touchdown on the Martian surface in Jezero Crater. This is the first-ever colour photograph ever taken of an alien surface. During the live press conference conducted by NASA, a scientist explained the first perspective details. He said that the rover was programmed to land on a plain surface, which is why a live surface detector was installed. Its job was to examine the surface before landing the rover. If any hazard was detected it could guide the rover to land on the safest spot. 

The scientist further revealed that the system was successful enough to avoid a dangerous landing spot.

The 2nd image showcases the Perseverance rover which is almost the size of a car. But surprisingly weighing only 1,025 kg is hung to the sky crane. Those wires are used to help it descend slowly. This method was used to avoid the blowing of dust which might have produced due to the thrusters and would have damaged the electronics of the rover. Later after the landing, this sky crane flew away and self-destructed itself after reaching a safe distance.

The 3rd image was taken after the successful landing of the rover. The tire visible is the right front tire of the rover. Further, the rocks visible on the left side of the image is very clearly seen to be different from a normal rock on the earth. This image is one of the many cameras situated in the rover. It’s a 20-megapixel camera used to click this picture.

A CNN journalist asked the NASA scientist about the holes formed that are visible on the rock, she further asked are these holes made by some pests? The scientist replied, cannot say anything without studying the image. She continued by saying, “There is two way of rock formation: volcanic and sedimentary. When rocks are formed by the cooling of lava, some gases present inside the lava make bubbles. This is why such holes are formed, the second type of rock formation is sedimentary, these types of rock holes can only occur if some fluid was flowing around it in the past. 

Meanwhile, NASA has also sent a helicopter which is named ‘Ingenuity’. This will be the first-ever test to check the Martian atmosphere. This test will determine the density of Mars’ atmosphere, and whether a vehicle with propellers can fly on the Martian surface or not.
