"Send a postcard to Tiangong Space Station: as long as 19 yuan?"

"China Aerospace Wenchuang Online Store put the Collection of Space Letters on the shelves for the first time, and users can send letters to China Space Station only by 19 yuan."

"Space letter set" includes special space stationery, special envelopes with stamps and two beautiful postcards. After netizens send personal letters to the nearest post office, these letters will be scanned into electronic versions and stored in chips, sent by spacecraft to the "space post office" on the space station, and even have the opportunity to be displayed and read by astronauts to the world.

When the florist first saw the news, he was really surprised. Writing paper, postcards, special envelopes, if you look at the volume and quality, it must be a conscience price to send to Tiangong Space Station! But I was puzzled to see that it was scanned into an electronic version and stored in the chip, and then sent to the "space post office" by spacecraft.

To be precise, it is to send an electronic scanning document to the Tiangong Space Station. According to the above introduction, it will be stored in a memory chip and sent to space. How much is the cost of sending chips?

Assuming it is easy to read, a USB flash drive is simple!

This operation is about the cost of sending a USB flash drive to the space station. A USB flash drive is about 10g (ordinary metal USB flash drive 7-8g). If the launch cost is 10000 USD/kg, the cost is about 100 USD!

A 1T USB flash drive costs about 1000 RMB, so the total cost is about 1700 RMB!

According to a scanned copy of 100KB-300KB (according to the standard format of PDF files, the DPI can be slightly lower, which will not affect reading), about 3.3 million to100000/9 blank letters can be stored, with a total value of 60 million to1900 million yuan. Of course, if it is,

Then the question is, will the weight of the U disk of so many files increase? If it is greatly increased, isn't the rocket transportation cost greatly increased? The answer is no, because that's only the change of 0 and 1, and it won't increase any macro quality!

In other words, the real cost of 1700 RMB will soon incite tens of millions to hundreds of millions of markets! It's very profitable, isn't it But it is not at all, because the cost of 19 yuan contains many valuable services:

In order to send your personal letter to the Tiangong Space Station, to be precise, the cost is extremely high. If there are overwhelming envelopes in the future, unpacking and sorting will require huge labor costs. It is estimated that a special team is needed to organize the operation. Of course, the cost of 19 yuan will filter out some unnecessary information, but I believe it will definitely consume a lot of energy!

Why can NSA be free? In fact, it is very simple, because the cost is not the chip, but the labor cost of sorting. NASA only designed a program to automatically log in and process these name files, that is to say, information based on electronic files can be processed by programs, but China Aerospace Wenchuang accepts your handwritten words, which is totally different from the effect of several "Song words" or English letters in a file!

From traditional documents to electronic documents, this does not reduce costs. Of course, this is also an element that combines modern aerospace with traditional culture. I am very supportive of China Aerospace, and this fee includes a large part of invisible expenses such as aerospace envelopes and postcards, scanning and sorting!

Further reading: What is the process of NASA sending signatures to Mars?

Very attractive title, and the content is more exciting. As long as you submit your name on NASA's website before September 30th, 20 19, you can get the boarding pass of NASA's rover "Perseverance" and engrave your name on a microchip, which will be carried on the rover and left on Mars forever.

Is it tempting, and there is a cool boarding pass for Mars, but in fact, this cost is the cost of a chip, because making a registered website and handling the final confirmation list is just a procedure, but from a sense, NASA's Sao operation is more modern and more convenient to participate. This small program has more than 6.5438+0093 million people worldwide, with the lowest cost. The publicity is global participation and it is also welcomed by everyone.

So can you refer to similar operation methods in the future?

In fact, in terms of publicity, China Aerospace is indeed inferior to NASA. We do more, talk less and find less information. We are catching up in the space field, but we should also keep up in propaganda.
