Voyager 2's Grand Tour of the outer solar system revealed a surprising cosmic neighborhood, where moons thought to be frozen and dead were churning with geologic activity, hiding potential subsurface oceans and possibly harboring life. Previous Post Next Post. Already a subscriber? Then, in AugustVoyager 1 was confirmed to cross the heliopause, the boundary of our solar system separating us from interstellar space. Each spacecraft had three computers with about 8, words of memory each, Stone says. Archived from the original on At this point I had seen Star Wars in the theater, my first remembered movie theater experience.
Voyager 1's course was optimized for the Titan flyby and Voyager 2 for the Grand Tour. Voyager 2 would reach Saturn nine months.

Voyager is planetary exploration on a grand scale. First conceived as a "Grand Tour" of the solar system from Jupiter to Pluto, then scaled back to a more modest. On March 5,Voyager 1 arrived at Jupiter, followed by Voyager 2 on July 9.
Suddenly, NASA's Jet Propulsion Laboratory (JPL) in.
It called for four spacecraft, two of which would visit JupiterSaturnand Plutowhile the other two would visit Jupiter, Uranusand Neptune.
Voyager 2 as well as Voyager 1 captivated me for my entire life.
What Voyager 2 Means to Me J. Dianne Dotson
We really didn't understand the system, because we thought Earth was sort of typical—and it is not. Sunlight was four times dimmer at Uranus and nine times dimmer at Neptune than it was at Saturn; Voyager 2 needed to be reprogrammed so its camera would take longer exposures.
Views Read Edit View history. Mack, Pamela E. Voyager 1 was so named because its goal was to reach Jupiter first, before Voyager 2.
A team of 10 full- and part-time flight engineers is in daily contact, although round-trip communication at the speed of light takes about 30 hours for Voyager 1 and 24 hours for Voyager 2.
The mosaic of 60 frames, snapped on February 14,captured the sun and six planets. With their cameras shut down and using only essential instruments to ration power from their ever-weakening plutonium batteries, they have reached the solar system's outer boundarya region called the heliosheathwhere solar winds collide with the interstellar medium.
The particular alignment occurs once every years. Sign in.

|They made me ponder my existence in what seemed a broadening universe.
The golden record depicting humanity was, at that time, a novel and groundbreaking idea.
Would its battery life last long enough for it to cross the heliopause? With Voyager 1 's mission complete, Voyager 2 was cleared for an extended mission to Uranus and Neptune, fulfilling the goal of a Grand Tour as proposed in Additionally, by launching Voyager 2 first, Voyager 1 's launch could be re-targeted to perform the Grand Tour if Voyager 2 were lost in a launch failure.
