Voyager 1 move to better study the flow of particles coming from the Sun

Old rockers never die ... or at least hide the age very well. So we could summarize the current status of a probe launched 33 years ago and already is at 17,400 million miles from Earth , crossing the boundary between the Solar System and interstellar space, not only still in touch with us, but still working, sending scientific data and valise, as occurred a few days ago, maneuvering for a better study environment.

And, after 21 years without making any such adjustment, the Voyager 1 turned back on itself, a total of 70 ° to permitr that one of its instruments, the Low Energy Charged Particle , to better capture the flow of particles, even at that distance, even coming from our star, and identify better which is your exact address ... something important, because the probe is and in the intermediate region lying between the "kingdom of Sun" and the interstellar medium, an area where both dimensions are so turbulent and the solar wind is completely stopped by external pressure.

" Since the solar wind direction changed and its radial velocity has been reduced to zero, we have to change the orientation of the Voyager 1 for the Low Energy Charged Particle can act as a kind vane to see which way the wind blows now. know the wind strength and direction is critical to understand how our solar bubble and estimate how much beyond this the edge of interstellar space r, "said Edward Stone, Voyager program director.

The last time the Voyager 1 turned on itself was the February 14, 1990, which could point their cameras to the Solar System that are leaving and make the first family photo of all the planets, including Earth , history, a feat that only now, this time from inside, got recently repeated MESSENGER . It was necessary to conduct a series of "test" to make sure he was able, after so long, to carry out this operation ... with results positive.

In fact so good that scientists hope to repeat it several times in the coming days and in the future. The "old lady" is, more than three decades after its launch in good shape and continues to send data from the farthest border, ready to jump into the unknown.
