The Mars panorama was taken last year, why was it released now?

On March 5, NASA released a 1.8 billion-pixel panorama of Mars on its official website. However, according to NASA, the Mars panorama was taken last year, but why was it only released this year? ? In fact, the panorama is made up of more than 1,000 high-definition photos. It was these more than 1,000 photos taken last year. It took scientists several months to put them together, so it has only been released now.

This panoramic view of Mars with a resolution of 1.8 billion pixels was taken by the U.S. probe Curiosity on Mars, and it is the result of the hard work and efforts of NASA scientists. First of all, it is a machine rather than a person who takes the photo, which makes it difficult to take the photo. Secondly, in order for these more than 1,000 photos to be spliced ??together flawlessly, scientists must ensure that the brightness and color of the photos taken are consistent. Therefore, scientists must control Curiosity to take photos between 12:00 and 2:00 noon every day. , which adds to the difficulty of this shooting work. At the same time, in order to give people a better visual experience, scientists also need to control Curiosity to find a better shooting angle. All in all, the challenges posed to scientists by this filming work can be described as very difficult.

After painstakingly taking more than a thousand photos, scientists spent several months carefully stitching these photos together. Therefore, the panorama taken last year went through various processes before being displayed in the It brings people visual shock before their eyes.

As you can see from the photos, the surface of Mars is desolate, with some pits and pits, as if they were caused by the drying up of water. In the past few years, scientists have also discovered water sources on Mars, which makes people feel sad. Question: Is there life on Mars? Will humans really immigrate to Mars in the near future? There are too many questions waiting for us to explore and solve. It is believed that with the continuous development of aerospace technology, mankind's understanding of Mars will gradually deepen.
