NASA’s scientists failed to stay seated when their eyes caught hold of the oscillations of the region around Voyager 1 on their instrument. It may sound hilarious what oscillations am I talking about! But it’s about NASA’s space-of-the-art Voyager that has “touched a milestone and is on its new journey,” as dubbed by Ed Stone, the mission's chief scientist at the Nasa's jet propulsion laboratory.
Well, Voyager 1 and 2 are the twins that science buffs in the 1970s must be accustomed to hearing. The Voyager 1 spacecraft is a space probe that was launched by NASA on September 5, 1977. The purpose of the program was to assess the outer Solar System and also the interstellar medium. For exactly 36 years and eight days on 12th September, 2013, the Voyager communicated with the Deep Space Network where it received regular commands and also provided the required data.
It is presently 125 AU from the Sun and thus is the farthest man-made project. It has an eight-track tape recorder, and computers with 240,000 times less memory than that of an iPhone and a nuclear reactor.
This is a stage where no one, even its creators, must have never even fantasized about. Now the speculated element is that how much power would be required for it to survive in the interstellar medium as the same has been decreasing with time. Till 2013, it was moving at a pace of 17 kilometers per second.
It has been made official that the Voyager 1 has entered into the cold, dark and anonymous region of interstellar space. The scientists have mentioned that most probable date when the same must have happened is August 25, 2012.
Voyager 1 started attracting some vibrations in April and May when the scientists calculated the density of the plasma surrounding the spacecraft.
They endeavored to find out whether the spacecraft was in the Solar System or not, and after the oscillations were studied they concluded that the Voyager has entered the much anticipated turf of interstellar space.
Voyager 2, which was a protracted part of the mission, was also sent for the purpose of locating and combing through the Solar System, thus, encapsulating the Kuiper belt, the heliosphere and the interstellar space. It was a maiden probe where the detailed images of the Jovian system and the Saturnian system were captured.
After the mission failed to hit the chord of NASA, its 12-person staff was asked to move from the Jet Propulsion laboratory campus and had to work down the street next to a McDonald's. The Voyager project manager Suzanne R. Dodd is excited about the media lights again hogging on the project. She hopes that the Voyager 1 would be sending the data back to the Earth with the aid of 23-watt transmitter till 2025.
