In which direction is the sun's stream of charged particles banking when it nears the edge of the solar system? Knowing the strength and direction of the solar wind is critical to understanding the shape of our solar bubble and estimating how much farther it is to the edge of interstellar space. Over the next several days, scientists at JPL will try a series of maneuvers to orient NASA's Voyager 1 spacecraft so that it can act as a "weather vane" and measure the solar wind. Even though Voyager 1 has been traveling through the solar system for 33 years and is 10.8 billion miles away, it is still a limber enough gymnast to perform the necessary acrobatics that it has not been asked it to do in 21 years.
