Space and Time: In this week's 10 Things blog we feature ways to travel both across the solar system and back in time, with a collection of NASA history sites and timelines. Use these resources to learn the stories and meet the people over the past several decades who dared to open up the final frontier.

Chaos at Hyperion: The small moon Hyperion tumbles unpredictably as it orbits Saturn. Hyperion, which is 168 miles or 270 kilometers across, has a spin axis with a chaotic orientation in time, meaning that it is essentially impossible to predict how the moon will be spinning in the future. So far, scientists only know of a few bodies with such chaotic spins. More: [ Go.nasa.gov Link ]

This high-resolution image shows the bright expanse of the western lobe of Pluto's "heart," or Sputnik Planitia, which is rich in nitrogen, carbon monoxide and methane ices. Scientists are probing the mystery of Pluto's icy heart using data from the New Horizons mission. Does Pluto hide a subsurface ocean?[ Go.nasa.gov Link ]
Mercury as it appeared to NASA's MESSENGER spacecraft as it departed the planet following the mission's first flyby of Mercury in 2008.
A camera aboard NASA's Lunar Reconnaissance Orbiter captured this look at Luna 17, the lander that delivered the Soviet Union's Lunokhod 1 rover to the surface of the moon. The rover's tracks are visible around the lander. The LRO team has compiled a full list of coordinates on the lunar surface where spacecraft have landed. Details: go.nasa.gov/2fNfoyT

1. Mars Ice Deposit Holds as Much Water as Lake Superior

Water ice makes up half or more of an underground layer in a large region of Mars, about halfway from the equator to the north pole. The amount of water in this deposit—assessed using a radar aboard NASA's Mars Reconnaissance...

Saturn's icy moon Mimas is dwarfed by the planet's enormous rings. Because Mimas (near lower left) appears tiny by comparison, it might seem that the rings would be far more massive, but this is not the case. Scientists think the rings are no more than a few times as massive as Mimas, or even perhaps just a fraction of Mimas' mass. More: [ Go.nasa.gov Link ]

Water ice makes up half or more of an underground layer in a large region of Mars about halfway from the equator to the north pole.
The amount of water in this deposit is about as much as in Lake Superior, as assessed using a radar aboard a NASA spacecraft orbiting Mars. This research advances understanding about Mars' history and identifies a possible resource for future astronauts. More:...
