| Researchers provided study participants with a series of blue or white cues and asked them to push one button or another depending on the direction of arrows. Brain imaging suggested that an area of the brain had ?learned? to recognize that blue cues indicated a greater potential for error, thus providing an early warning signal that negative consequences were likely to follow their behavior. |

Europa

|  | Europa ice shell
 |
| NASA/JPL |
| Thick or thin ice shell on Jupiter’s moon Europa?
Scientists are all but certain that Europa has an
ocean underneath its surface ice, but do not know how thick this ice might be. This artists’ conception illustrates two possible cut-away views through Europa’s ice shell. In both heat escapes, possibly volcanically, from Europa’s rocky mantle and is carried upward by buoyant oceanic currents. If the heat from below is intense and the ice shell is thin enough (left), the ice shell can directly melt, causing what are called “chaos” on Europa, regions of what appear to be broken, rotated, and tilted ice blocks. On the other hand, if the ice shell is sufficiently thick (right), the less intense interior heat will be transferred to the warmer ice at the bottom of the shell, and additional heat is generated by tidal squeezing of the warmer ice. This warmer ice
will slowly rise, flowing as glaciers do on Earth, and the slow but steady motion may also disrupt the extremely cold, brittle ice at the surface. Europa is no larger than Earth’s moon, and its internal heating stems from its eccentric orbit about Jupiter, seen in the distance. As tides raised by Jupiter in Europa’s ocean rise and fall, they may cause cracking, additional heating, and even venting of water vapor into the airless sky above Europa’s icy surface.

| NASA/JPL |
| Possible Sequence of Europa Exploration. Almost 30 years ago, Voyagers 1 and 2 (lower left) made their historic rendezvous with the Jupiter system, and first revealed Europa’s icy covered surface to human eyes.
In 1995 the Galileo spacecraft went into orbit about Jupiter, and for years studied the giant planet and its major moons. From this mission, we learned that Europa is a world covered with a global ocean about 100 km (60 miles) deep, and that this ocean was capped, liked the Earth’s Arctic Ocean, with a shell of solid ice. To learn more about this ocean and the ice shell above, and especially to investigate ocean’s suitability to sustain life, will require the next step, a future mission dedicated to exploring Europa from orbit about the moon itself (center). Both NASA
and ESA (the European Space Agency) are actively studying launching such a mission in the next 10 years. If such a mission is launched, and depending on what is found, future missions to Europa may involve landers or even autonomous vehicles - called cryobots (upper right) - that melt through the ice to explore the ocean below, perhaps sometime later in this century. |
