Aerospace photography technology

On March 5th, NASA released a 654.38+0.8 billion pixel panorama of Mars in official website, but according to NASA, the panorama of Mars was shot last year. Why was it released this year? In fact, panoramic photos are made up of more than 1000 high-definition photos. It was this 1000 photo taken last year. It took scientists months to piece them together, so it's just released now.

This panoramic view of Mars with a resolution of 65.438+0.8 billion pixels was shot by the American Mars probe Curiosity, which embodies the painstaking efforts and efforts of NASA scientists. First of all, it is the machine that takes pictures, not people, which makes it difficult to take pictures. Secondly, in order to make these 1000 photos perfectly spliced together, scientists also need to ensure that the brightness and color of the photos taken are consistent. So scientists control Curiosity to shoot between 12: 00 and 2: 00 every day, which increases the difficulty of this shooting. At the same time, in order to give people a better visual experience, scientists have to manipulate Curiosity to find a better shooting angle. In a word, the challenge brought by this shooting work to scientists can be described as very arduous.

After painstakingly taking more than 1000 photos, it took scientists several months to combine these photos closely, so the panorama taken last year was presented to people after various treatments, which brought people a visual shock.

As can be seen from the photos, the surface of Mars is desolate, and there are some potholes, such as those caused by dry water. In the past few years, scientists have also found water on Mars, which makes people wonder: Is there life on Mars? Will humans really immigrate to Mars in the near future? Too many problems are still waiting for us to explore and solve. It is believed that with the continuous development of space technology, human understanding of Mars will gradually deepen.
