NASA’s Voyager 1 To Enter The Interstellar Space; Passes "Magnetic Highway"

Now in its 35^th year of journey and 18 billion kilometers away from the Sun, NASA’s Voyager 1 Spacecraft is now on what scientists believe as the final stretch the spacecraft has to travel before making its way to the interstellar space. The region that the spacecraft has to cross is a 'magnetic highway' for charged particles. This is the region where Sun’s magnetic field lines and connected to interstellar magnetic field lines. The Voyager team in NASA’s Jet Propulsion Laboratory at Pasadena, California states that the spacecraft is still inside the solar system as the direction of magnetic field lines has not changed and that the change would happen only when the spacecraft crosses the solar bubble of charged particles blown by the sun and goes to interstellar space.

On July 28^th 2012, the spacecraft entered this region for the first time and the onboard instruments meant for checking charged particles measured these changes and reported them back to base. On August 25^th the spacecraft again entered this region and has been in the same region ever since because the reading on the magnetic charged particles has remained at the same level ever since. Scientists are still working on data sent by the farthest object sent by man into outer space and we hope that the spacecraft makes its way to the interstellar space very soon.
