Hot space projects produce cool cosmic discoveries

NASA, ESA and others' spacecraft and telescopes find new planet, make sense of old ones and solve cosmic mysteries

Saturn's icy moon: NASA's Cassini spacecraft took pictures of a forest of new ice jets spraying from prominent fractures crossing the south polar region of Saturn's moon Enceladus and yield the most detailed temperature map to date of one fracture, NASA says. The images include the best 3-D image ever obtained of a "tiger stripe," a crevice that sprays icy particles, water vapor and organic compounds. For Cassini's visible-light cameras, the flyby provided the last look at Enceladus' south polar surface before that region of the moon goes into 15 years of darkness, NASA says.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
