Recently, the U.S. NASA announced 1.8 billion pixels Mars landscape panoramic photo, the photo was taken between November 24, 2019 and December 1, 2019, with 1,000 photographs after several months of processing combined, the pixel as high as 1.8 billion pixels, so that the surface of the surface of the surface of the Martian situation is clearly shown in front of human eyes, then 1.8 billion
What is the concept of 1.8 billion pixels?
The photo resolution is as high as 1.8 billion pixels, and the image file is as high as 2.25GB. We know that we usually use our cell phones to take pictures, and a high-resolution, brightly colored picture is only a few dozen megabytes, and at present, the pixels on the highest-performance cell phones only have a pixel rating of 40 megapixels, or a little higher than 50 megapixels, and the price is very high. The price is also very high. Compared to the highest pixel count on a cell phone, 1.8 billion pixels is 45 times the pixel count on a cell phone! This photo is really unparalleled clarity, a small grain of sand can be seen the kind of people y for the shock.
The NASA scientists went to great lengths to take this unique photo. In order to ensure the brightness and color consistency of the photos taken, scientists need to manipulate the Curiosity to shoot between 12:00~2:00 pm every day, and at the same time, in order to have a better shooting angle, scientists decided to let the Curiosity to climb up a huge hill to have a better view. It was only through precise work day in and day out that an unparalleled photo was presented to the people.
Through the photo, people can clearly see the giant crater and small rocks on the ground of Mars, which makes people wonder about the advanced technology. With the continuous development and progress of aerospace technology, people's exploration of Mars from a distance to field trips, inseparable from the efforts of researchers and human thirst for the unknown. There are still countless unknowns on Earth, for the universe, we know even less, so we have to learn a lot of knowledge, continue to explore, continue to learn, we will solve more unsolved mysteries.
