Nasa begins a ‘matar’ probe Voyager; 15 greatest pictures of missão – 24/06/2022 | Aici


Pioneers in house exploration, as probes Voyager 1 and a pair of have been longer than any human object on the fringe of the Photo voltaic System. Mas cheguo a hora de iniciar a despedida dessa jornada pelo Universo, que já dura quase 45 years.

There’s an irreversible downside: a delas está abacando power. Para economizar o que resta, os scientias da NASA, agência espacial dos Estados Unidos, estão desligando seus instrumentos aos pouces. O objetivo é que as duas continuem minimalamente vivas por mais alguns anos colletando os principales dados cientificos.

“Se tudo correr muito bem, perhaps we are able to prolong the missions till the last decade of 2030. Dependence apenas da energia. Este é o ponto limitante”, mentioned Linda Spilker, planetary scientist of the Japanese Propulsion Laboratory (JPL).

Their cameras have been turned off in 1990, after Voyager 1 took the final pictures, often known as the “household portrait of the Photo voltaic System”. Assim, priorizou-se a eletricidade (gerada por plutônio) ea memória do sistema para os instrumentos que analizariam o annão desconhecido espaço interestelar.

Is it passram?

As sondas gémeas have been launched in 1977, para explorar planetas exteriores — principally Jupiter, Saturno, e suas luas. As fotos que tiraram foram reveladoras e estampam livros escolares até hoje.

Depois, seguiram viagem por caminhos e velocidades diferentes, até cruzarem as fronteiras do Sistema Photo voltaic, getting extra removed from Earth than any object made by people.

In 2012, Voyager 1 turned the primary ship to achieve interstellar house — whether it is chaotic exterior the “bolha” of the affect of the Solar, between the opposite stars of the galaxy.

In 2018, Voyager 2 performs an vital function. Um feito que deve devera decasa para ser repetido por outra missão.

Expectativa de vida

Previstas para durarem meros quatro anos, elas já superaram em mais de dez vezes as expectativas. Regardless of the consequences of time and radiation, we proceed to obtain instructions and transmit knowledge — radio alerts take as much as 19 hours to achieve right here.

At present, Voyager 1 is 23.3 billion kilometers from Earth, with an estimated velocity of 17 km/s. Voyager 2 reaches 19.4 billion, 15.4 km/s. E contando.

The space and standing of the devices might be discovered on the NASA mission web page.

Is it carregam?

Regardless of the title, Voyager 2 was launched first (20/8/1977) than Voyager 1 (5/9/1977). São naves are precisely the identical.

The board has three mills and 11 devices, operated by primitive computer systems, together with a big antenna, a magnetometer, spectrometers and programs to measure plasma and cosmic rays. Alguns pararam de funcionar nos últimos anos.

Every probe additionally produces a “Disco Dourado”: an LP with 115 codified photographs, audio in 55 languages, 12 minutes of our planet’s sounds and 90 minutes of music. If a pattern of humanity is in our location for potential extraterrestrial civilizations.

Depois de “morrerem” e perderem contato com a Terra, elas continuarão traversando o Universo indefinidamente, passando por outras estrelas. Proxima Centauri ought to be reached in 16 million and 20 million years, respectively, by Voyager 1 and Voyager 2.
