After 20 years and 5 billion miles traveled, NASA's Cassini spacecraft will plummet Friday into Saturn, the planet it knows best.
Since 2004, Cassini has orbited the ringed behemoth more than 290 times, getting up-close looks at the planet, its moons and icy rings like no other man-made object has before. Its instruments beamed back more than 450,000 beautiful — and scientifically revealing — images during its lonely mission beyond the asteroid belt.
But as Cassini death dives into Saturn's atmosphere and melts into oblivion, you can keep the mission going by adding some of these NewsHour-crafted backgrounds to your computers and smartphones. Click each photo to access the wallpapers.
