On a recent Amazon Prime Day sale, purchasedThe Amazon Kindle Paperwhite e-book, which was licking for a long time, so the price of $ 79.99 left no chance for my toad. However, branded cases didn’t think of getting cheaper, so I bought Ali not the cheapest, but very attractive cover with the Voyager 1 print, this option caused a storm of positive emotions in connection, so to speak, with the memory of a childhood dream ...
I think I will not be mistaken if I say that manyThe readers of my generation, growing up in the 80s, were read in the available science fiction (Strugatsky, Efremov, Snegov, Bradbury, Asimov, Symak, Harrison and many others), dreamed of stars that seemed to be just a little bit more and close and dear, we will meet, at last brothers in mind, and on Mars, nevertheless, I will bloom apple trees. We were looking forward to the new edition of “Young Technique”, “Youth Technique” or “Around the World”, where, in addition to popular articles and application schemes for the hands of weak, but inquisitive boyish minds, science fiction was regularly published, both sometimes in the form of a series stretched for a dozen or two issues and, somehow, it all contributed to the popularization of space, and the astronauts for us, indeed, were heroes.
I don’t remember when I first read aboutflight “Voyager 1”, but the information about it made a big impression and got on the “shelf” in the brain, with such events as the launch of the first satellite, the first flight of Yuri Alekseevich Gagarin, spacewalk of Alexei Arkhipovich Leonov, docking “Soyuz-Apollo "(Oh, how many models I have re-glued in childhood!), The flight of the Buran and other landmarks of space exploration by man. Therefore, no, no, yes, and in the brain of an adult peasant, memories of childhood impressions and dreams will pop up, when something comes to mind that resembles them. So it happened with this case, took without hesitation
If someone doesn't remember, then the Voyager project ismission from the Voyager 1 and Voyager 2 devices (weight: 798 kg, payload weight: 86 kg. Length: 2.5 m), launched with a difference of 3 weeks in 1977. Devices are automatic interplanetary stations for the study of distant planets of the solar system. At the moment, this project is considered the most successful in the history of interplanetary research. It is difficult to imagine that the vehicles, whose mission was designed for 5 years, are still functioning and are still capable of transmitting data about the surrounding space. On board the devices there is a large number of recording equipment, which allows to obtain photographs and a sufficiently large amount of measured data. The wiki describes this in detail:
You can monitor the status and removal of devices in real time on the NASA website. here.
A LITTLE MORE ABOUT VOYAGER
The initial objectives of the mission, namely, the studyJupiter and Saturn, long over-fulfilled, made a successful flight past Uranus and Neptune, and in front of outer space. It is thanks to these devices that detailed images were obtained not only of the planets themselves, but also of their numerous satellites, about which information was practically absent before.
Photos from the board "Voyager 1"
Earth and Moon from a distance of 11.66 million km:
A volcano on the satellite of Jupiter Yo, a big red spot of Jupiter, the crater of Valhalla on the satellite of Jupiter Callisto, rings of Saturn:
“Farewell Photo” - “Pale Blue Dot” (“PaleBlue Dot ”) is one of the most famous photos taken by the Voyager-1 apparatus in 1990. In the picture, the Earth was photographed from a distance of 6 billion km.
In September 2013, NASA officially announcedthat Voyager-1 finally left the solar system and became the first device in history to reach the limits of the solar system and go beyond its limits, although scientists still argue what to consider as its boundaries. The boundary of the solar system is determined, as a rule, as the boundary of the heliosphere - the area filled with the solar wind, that is, the flow of charged particles emanating from the sun. The zone where the pressure of the solar wind is balanced by the pressure of interstellar charged particles is the boundary of the heliosphere and is regarded as the boundary of the solar system and interstellar space.
Voyager 2 is no less successful than its counterpart, but moves along a different trajectory
He, besides those planets and satellites that could"Take a picture" "Voyager 1", managed to explore Uranus, Neptune and their satellites, as well as the satellites of Jupiter - Europe and Ganymede. The transmitted images allowed the hypothesis of the existence of a liquid ocean under the surface of Europe.

Power equipment apparatuses
The source of electricity are threeradioisotope thermoelectric generator (RTG). Plutonium-238 serves as fuel in them; their power at the time of the launch of the spacecraft was approximately 470 watts at a voltage of 30 volts DC. The half-life of plutonium-238 is approximately 87.74 years, and generators using it lose 0.78% of their capacity per year. In 2006, 29 years after launch, such generators should have a power of only 373 W, that is, about 79.5% of the original. In addition, the bimetallic thermocouple, which converts heat into electricity, also loses its efficiency, and the actual power will be even lower. On August 11, 2006, the power of the Voyager-1 and Voyager-2 generators decreased to 290 and 291 W, respectively, that is, about 60% of the power at the time of launch. These indicators are better than pre-flight predictions based on a conservative theoretical model of thermocouple degradation. With a drop in power, the power consumption of a spacecraft has to be reduced, which limits its functionality. By 2012, electrical power has fallen by about 45%. However, it is expected that the minimum power supply for research will be maintained until approximately 2025.
November 28, 2017 at Voyager 1 were successfulfour engines of trajectory correction MR-103, which were not included for more than 37 years, were tested with 10-millisecond inclusions since November 8, 1980, when Voyager-1 was located near Saturn. In the future, these engines are supposed to be used, if necessary, instead of a set of orientation engines (of the same type), which from 2014 show signs of some deterioration in performance.
It is assumed that Voyager 1 will fly tostars In about 40,000 years, it should fly 1.6 light years (15 trillion km) from the star AC + 79 3888 of the Giraffe constellation, which moves towards the constellation Ophiuchus. In the future, probably, "Voyager-1" will forever wander through the Milky Way galaxy.
It is assumed that Voyager-2, in 40,000 years, will pass at a distance of 1.7 light years from the star Ross 248a, approximately in 296 thousand years it will be diverted from Sirius at a distance of 4.3 light years.
About the product.
The product arrived in a simple transparent package (whole):
Workmanship is excellent. The print is very bright, quite clear and sharp:
The surface of the coating has an interesting texture:
On the reverse side there is a photo of a disk with a message to extraterrestrial civilizations:
MESSAGE TO THE EXTERNAL CIVILIZATIONS OF VOYAGERS
A round one was attached to the board of each Voyager.aluminum box, putting there a gold-plated video disc. The disk contains 115 slides containing the most important scientific data, views of the Earth, its continents, various landscapes, scenes from animal and human life, their anatomical structure and biochemical structure, including the DNA molecule.
In the binary code, the necessary explanations andindicated the location of the solar system relative to 14 powerful pulsars. The hyperline structure of the hydrogen molecule (1420 MHz) is indicated as a “measured ruler”.
In addition to images, the disc recorded and sounds: the whisper of the mother and the crying of the child, the voices of birds and beasts, the noise of the wind and rain, the roar of volcanoes and earthquakes, the rustling of the sand and the ocean surf. You can read the records for this reference.
Human speech is presented on a short disk.greetings in 55 world languages. In Russian it says: “Hello, I greet you!”. A special chapter of the message is the achievements of world music culture. The disc contains works by Bach, Mozart, Beethoven, jazz compositions by Louis Armstrong, Chuck Berry, and folk music from many countries.
Total records contain:
- music (78% of audio recordings of the disc),
The engraved instructions for using the disc are engraved on the case, the phonographic capsule and needle were also packed.
Very interesting about the development of the disc is written here.
By the way, disputes still do not stop, it is worthwhether to declare oneself "at all frequencies" to potential "neighbors" in space, between supporters and opponents of the options of "open contact" and "seclusion". On this topic, I advise you to read the fantastic trilogy “The Task of the Three Bodies” by the Chinese science fiction writer Liu Cixin, a very entertaining reading and an interesting look on this topic.
Cover in the opened form. The case is plastic, protects the book from all sides. The cover has a soft coating under artificial suede:
The book was inserted without any problems and sat tightly in the case:
All corners and notches in place, no gap anywhere:
In the center of the right side is a ledge, it is convenient to open an e-book:
At this point in the cover of the cover (between the layers) there is a magnet that activates the sensor of the book: it turns on when the cover is opened, and turns off when closing:
In fact, thanks to the commentators, there are two magnets and one that is responsible for falling asleep, below:
If you bought the Kindle, but saved on the cover- I definitely recommend a review or similar to it, there are different design options and prints. Well protects the book, it is comfortable in the hand, the surface texture does not allow it to slip, the cover can be bent to the “back” of the cover while reading and held between the index and middle fingers, the grip is comfortable, the hand does not get tired. The collage depicted on the print is, of course, even theoretically impossible, it is unlikely that this will happen that Voyager can fly beyond our Galaxy, but this thing gives me only positive emotions in connection with what was said at the beginning of the review and, despite the fact that space , still far, and those who look at the stars have become much less ... I want to believe ...
