NASA Cassini and Voyager To Scale The Space
Space Scientists are now on the verge of calculating the distance to interstellar space thanks to the data sent by Cassini-Huygens mission ‘s Cassini spacecraft and NASA’s Voyager. The data received till now has shown the existence of a much thicker "transition zone" at the edge of our solar system than previously anticipated.
The study has shown that the thickness of the region between the charged particle bubbles around sun and the interstellar space is around 18 billion Kilometers. Voyager, with a speed of a billion Kilometers in three years can reach the boundary of interstellar space any time soon. Scientists have also recorded a very useful data last year in December sent by voyager 1 indicating that the outward speed of the charged particles from the sun has reduced to zero. The data from Voyager1 mission assumes a little more importance than that of voyager 2 owing to the fact that voyager 2 is still 14 billion kilometers away from the sun, pretty lagging behind 1.

Meanwhile, the spacecraft Cassini’s plasma spectrometer instrument was shut down due to a voltage shifts in the spacecraft. The managers of the mission suspended to prevent any further damage because the instrument is designed to operate on stable voltage. The capacitors incorporated in plasma spectrometer instrument for noise reduction might have short circuited which affected the instrument to change its voltage. Even after shut down, all the other data sending facilities from Cassini are going on smoothly and the problems with plasma spectrometer instrument would soon be sorted out.
Cassini’s data is used to tally those from that of Voyager. Tom Krimigis is the principal investigator for Voyager's low-energy charged particle instrument and Cassini's magnetospheric imaging instrument. He and his team have combined both data on neutral atoms streaming into our solar system from the outside to reach the conclusion of distance to interstellar space.
The voyager 1 is a long term mission of NASA and was started way back in 1977. Since then it is travelling continuously for 33 years to reach the boundary of space. The spacecraft upon reaching the boundary will reveal amazing information about our surrounding outer space.
