Humanities only interstellar ambassadors, the Voyager spacecraft, are on the verge of entering deep space. NASA has previously predicted that Voyager 1 would make the transition to deep space sometime during 2012 or 2013, now instruments on-board Voyager 1 suggest the transition to deep space may be very close.
Voyager 1’s instruments are indicating a steep increase in galactic cosmic rays, one of the indicators that Voyager 1 is entering deep space, leaving the safety of the heliosphere. Protecting the solar system from cosmic radiation the Heliosphere is part of the Sun’s magnetic field and marks the boundary between our solar system and interstellar or deep space.
At 18 billion kilometers from the sun Voyager 1 has already traveled an incredible distance. Communications now take 16 hours and 38 minutes to reach NASA’s network on Earth, while the Voyagers continue traveling at a speed of 17 kilometers per second towards the unknown.
