While today may belong to the 45th anniversary of the Apollo 11 lunar landing, it’s important not to forget another important anniversary for NASA - the landing of the Viking 1 spacecraft on Mars!

On July 20th, 1976, the Viking 1 lander separated from the orbiter and touched down at Chryse Planitia, a flat lowland region in the northern hemisphere of Mars. Immediately following touchdown, the lander made history by taking and transmitting the first complete photograph taken from the surface of Mars. The image (http://goo.gl/6C5L6m) was of the Viking 1 lander’s foot as an indication of how far it had sunk into the Martian surface. Between itself and its companion, Viking 2, this historic photograph was just the first of more than 50,000 images taken from the Martian surface, as well as from orbit, and transmitted back to Earth.

What makes Viking 1 especially worth noting is that it was not only the first attempt by the United States at landing on Mars, but it was also the first spacecraft to successfully do so and perform its mission. While the Soviet Mars 3 mission was the first to achieve a soft landing of a spacecraft on Mars it stopped transmitting data 15 seconds after landing. During those few seconds of transmission, it sent the first partial photograph taken from the surface of Mars although nothing was identifiable in it.

During its operation on the Martian surface, Viking 1 became the record holder for longest Mars surface mission at 2307 days, until Mars Rover Opportunity took the record in 2010.

Marte...

Nossa viagem de hoje nos leva a outra mundo e ao ano de 1975, quando a NASA lançou a sonda Viking 1 em direção ao planeta vermelho, com a função de estudar o despovoado lugar. Esta sonda descobriu a existência de formas geológicas que se formam por existência de água e causou uma revolução na forma de se pensar sobre Marte. Porém, não conseguiu encontrar vida, o que causou uma grande frustação para o pessoal da NASA.

No começo de 2012, uma sonda Russa que havia ido passear em Marte caiu na Terra. Muito se falou do perigo que esta situação apresentava, mas por sorte a sonda Fobos-Grunt, de 13,5 toneladas, caiu no Oceano Pacífico, perto da costa do Chile.

Recentemente foi lançada a sonda Curiosity carregada de câmeras para que possamos seguir estudando o Planeta Vermelho e a possibilidade de habita-lo, em um breve futuro. Pesquisando, achei engraçado porque assim como a ida do Homem a Lua, já tem gente falando que as imagens de Marte são falsas, veja:

E como estamos na Via Marte, ai vai:

Até amanhã, a gosto nosso!
