Next Mars rover will have 23 'eyes'

more »
NASA's Mars 2020 mission will have more "eyes" than any rover before it: a grand total of 23, to create sweeping panoramas, reveal obstacles, study the atmosphere, and assist science instruments. They will provide dramatic views during the rover's descent to the Red Planet.

Modeling surface chemistry, predicting new materials

more »
The ruddy flakes of a rusted nail are a sure sign that an undesirable chemical reaction has occurred at the surface. Understanding how molecules and atoms behave with each other, especially at surfaces, is central to managing both desirable chemical reactions, such as catalysis, and undesirable reactions, like a nail’s corrosion. Yet the field of surface chemistry has been challenged for nearly 100 years to develop predictive theories for these reactions. Now there’s progress, thanks to some new approaches.

Return of the comet: 96P spotted by ESA, NASA satellites

more »
Sun-gazing missions SOHO and STEREO watched the return of comet 96P/Machholz when it entered their fields of view between Oct. 25-30. It is extremely rare for comets to be seen simultaneously from two different locations in space, and these are the most comprehensive parallel observations ever taken of this comet.
