Mars slogan video

On February 23rd, NASA released a video from Mars. This video was sent back to Earth by the Mars probe "Perseverance" launched in July 2020. Just five days ago, it had just completed more than six months of space flight and finally reached the surface of Mars.

This is a well-crafted video documentary, which records the precious moments from the parachute opening to the landing of Perseverance from all angles through multiple cameras installed on the launcher. It also quickly became the most popular video, and reached the forefront of Youtube hot list in just one day.

It is not surprising to slow down and repeat the opening of the umbrella in space clips. But this video not only deliberately chooses two different angles, but also has a parachute with a strange pattern that people can't move-just like trying to let the audience see the whole picture.

Viewers who are already familiar with NASA's tricks soon realize that this is a carefully prepared egg. Before this, a spokesman from NASA revealed that because I hope that space work can inspire others, I sometimes leave some information in my work for people to find answers.

The audience who found the secret quickly threw themselves into solving the puzzle. A Twitter user named FrenchTech_paf became the first decipherer. He found that as long as the red part is regarded as "1" and the white part as "0", it can be simplified to a simple binary pattern.

As long as the pattern is slightly cut, it will become a regular pattern. Using binary rules, the parts painted red in these pictures can be converted into corresponding English letters. From the inside out, the parachute can be regarded as four concentric rings, and the red letter of each ring can be interpreted as the corresponding information. Draw the decoding result of FrenchTech_paf on the parachute, and the result will be vividly displayed.

If you draw it more intuitively and exclude useless interference elements, such as big red and white parts, then each dividing line can get their corresponding answers.

The digital information in the inner three circles can be converted into letters and arranged clockwise to obtain "something brave". This sentence means "challenge great things". It has always been the motto of the Perseverance Working Group. It is printed on the wall of the working group office.

The outermost password was quickly uncovered, and 3411'58 "n11810' 31"w obviously points to a certain place. According to the given coordinates, you can find that this is actually the location of JPL (JPL belongs to NASA and is also an important part of the Mars program).

Although the secret of the parachute has been revealed, the surprise brought by Perseverance does not stop there. In the picture sent back by Perseverance, the audience quickly found another egg: on the back of this Mars probe, the portraits of predecessors who landed on Mars in past dynasties were engraved, from 1996, the pioneer of Mars scientific exploration, to Perseverance and the first Mars drone, all arranged neatly together.

More secrets are waiting to be discovered, and the unknown universe is waiting to be explored. It is respectable that while adhering to the principle of "challenging great things", some people still remember to share the romance of science and the universe with the world.
