Two spacecraft See Volcanoes on Io.

Jupiter's Radiation is Even Stronger than Originally Thought
NEXT SHUTTLE MISSION WILL DELIVER CANADIAN ARM
Preparations are underway for the next stage of the construction of space station Alpha. Due to launch April 19th, the Space Shuttle Endeavour will carry a seven-member crew and deliver a Canadian-build robotic arm to the station. Similar to the Canadarm used on most shuttle missions, the Canadarm2 or Mobile Servicing System will be much longer, and capable of moving around the station like an inchworm

GIANT SOLAR STORM HEADED OUR WAY
Astronomers watching the Sun have reported that a giant coronal mass ejection (CME) is heading directly towards the Earth and should reach us within the next 24 to 36 hours. The CME was ejected from the Sun out of one of the largest clusters of sunspots seen in several decades. scientists expect we'll have a geomagnetic storm when the CME hits our atmosphere, including communications interference and some spectacular aurorae, visible from lower latitudes.
TWO spacecraft SEE volcanoes ON IO
In a recent team-up with Cassini and Galileo, the two spacecraft took some spectacular images of huge volcanic plumes on Io, Jupiter's volcanic moon. Combined information from the two spacecraft indicate that the new plume is 400km high, and originates from the Tvashtar Catena near Io's north pole. NASA scientists would like to try to fly Galileo directly through the plume if it lasts until August.
JUPITER'S RADIATION IS EVEN STRONGER THAN ORIGINALLY THOUGHT
During its recent flyby in December, Cassini used an Italian-built instrument to measure Jupiter's powerful radiation belts, and determined they're more powerful than originally estimated. Until now, scientists had no way to directly measure Jupiter's radiation, which has taken its toll on the Galileo spacecraft, still orbiting the Jovian system. Future missions, especially a proposed one which will bring a spacecraft within 2,500 kms of the planet's surface will need to be adequately shielded from the radiation.
