Voyager assembly in Hi-Bay I.
With an eight-track tape recorder and 100,000 times less memory than an iPod, Voyager 1 is celebrating its 35th birthday at the edge of the solar system.
Traipsing through a giant, turbulent, plasma bubble near the fringes, the longest-running, most-distant spacecraft in NASA's history celebrates a launch anniversary on Wednesday. After more than three decades of trekking, the craft is currently flirting with the edge of our system, poised for a precedent-setting puncture to the other side.
Scientists say the milestone is near, but a timeframe for crossing over is unknown.
Expected to be the first manmade object to touch the space between stars, Voyager 1, at more than 11 billion miles from the sun, is already in uncharted celestial territory. Voyager 2, which celebrated its anniversary two weeks ago, is approximately 9 billion miles from the sun.
This Jan. 5, 2012 image provided by NASA shows bright and dark material at the rim of the Marcia crater on the Vesta asteroid, taken by NASA's Dawn spacecraft. The lighter areas of the crater's edge is causing high interest and speculation by NASA scientists.
The NASA Dawn spacecraft mission has made some surprising discoveries about the asteroid Vesta, the parent body of an asteroid belt between Mars and Jupiter.
Carol Raymond, with the Jet Propulsion Laboratory, told KPCC that the data Dawn gathers could help scientists better understand how Earth and other planets emerged.
"Vesta’s history appears to be more similar to rocky terrestrial planets - Mars, Mercury, and the Earth’s moon - than to its larger sibling Ceres, which will be the second target of the Dawn mission," says Raymond.
Scientists say cosmic collisions, likely with a smaller asteroids, are to blame for Vesta's scars. High-resolution images have revealed, however, that two massive overlapping craters are creating the huge depression (the southern hemisphere depressions were first seen the Hubble Space Telescope).
