NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space.
NASA's Voyager 2 has successfully switched to the backup set of thrusters that controls the roll of the spacecraft.
NASA's Deep Space Network personnel sent commands to the Voyager 2 spacecraft Nov. 4 to switch to the backup set of thrusters that controls the roll of the spacecraft.
Those who study the sun face an unavoidable hurdle in their research â€“ their observations must be done from afar. Relying on images and data collected from 90 million miles away, however, makes it tough to measure the invisible magnetic fields sweeping around the sun.
NASA said Wednesday that Voyager 1 could cross over into the frontier of interstellar space at any time and much earlier than previously thought.
NASA said on Thursday that its Voyager spacecraft has helped to show that the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles.
WASHINGTON, June 9, 2011 /PRNewswire-USNewswire/ -- Observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles approximately 100 million miles wide.
In a paper to be published in the April 10, 2011, issue of The Astrophysical Journal, scientists on NASA's Interstellar Boundary Explorer (IBEX) mission, including lead author Nathan Schwadron and others from the University of New Hampshire, isolate and resolve the mysterious "ribbon" of energy and particles the spacecraft discovered in the heliosphere â€“ the huge bubble that surrounds our solar system and protects us from galactic cosmic rays.
NASA's Voyager spacecraft are hurtling towards the edge of our solar system, more than 10 billion miles away from our sun. Interstellar space - the medium between stars - is a region no human-made craft has ever been.
Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...
