Space Missions

 

The spinning vortex of <a href="https://www.windows2universe.org/saturn/saturn.html">Saturn</a>'s north polar storm resembles a giant deep red rose surrounded by green foliage in this false-color <a href="http://www.nasa.gov/mission_pages/cassini/multimedia/pia14944.html">image</a> from NASA's <a href="https://www.windows2universe.org/missions/cassini.html">Cassini spacecraft</a>. The eye is 2,000 kilometers across with cloud speeds as fast as 150 meters per second.
It is not known how long this newly discovered north-polar <a href="https://www.windows2universe.org/earth/Atmosphere/hurricane/hurricane.html">hurricane</a> has been active.
The view was acquired at a distance of approximately 419,000 kilometers from Saturn.<p><small><em>NASA/JPL-Caltech/SSI</em></small></p>According to <a href="http://www.jpl.nasa.gov/news/news.php?release=2013-277">NASA scientists</a>, the Voyager 1 spacecraft entered interstellar space in August 2012, becoming the first spacecraft to leave the <a href="/our_solar_system/solar_system.html&edu=elem&dev=1">solar system</a>. The space probe is about 19 billion km from the <a href="/sun/sun.html&edu=elem&dev=1">Sun</a>.  <a href="/space_missions/voyager.html&edu=elem&dev=1">Voyager 1 and 2</a> were launched in 1977 on a <a href="/space_missions/voyager.html&edu=elem&dev=1">mission</a> that flew them both by <a href="/jupiter/jupiter.html&edu=elem&dev=1">Jupiter</a> and <a href="/saturn/saturn.html&edu=elem&dev=1">Saturn</a>, with Voyager 2 continuing to <a href="/uranus/uranus.html&edu=elem&dev=1">Uranus</a> and <a href="/neptune/neptune.html&edu=elem&dev=1">Neptune</a>. Voyager 2 is the longest continuously operated spacecraft. It is about 15 billion km away from the <a href="/sun/sun.html&edu=elem&dev=1">Sun</a>.<p><small><em>Image courtesy of NASA</em></small></p>
