Rosetta's Philae probe lands on comet
ScienceDaily
ESA's Rosetta mission has soft-landed its Philae probe on a comet, the first time in history that such an extraordinary feat has been achieved. After a tense wait during the seven-hour descent to the surface of Comet 67P/Churyumov-Gerasimenko, the signal confirming the successful touchdown arrived on Earth. The confirmation was relayed via the Rosetta orbiter to Earth and picked up simultaneously by ESA's ground station in Malargüe, Argentina and NASA's station in Madrid, Spain. The signal was immediately confirmed at ESA's Space Operations Centre, ESOC, in Darmstadt, and DLR's Lander Control Centre in Cologne, both in Germany.

GEOCHEMISTRY IN THE NEWS


International scientific society reacts to L'Aquila seismologists acquittal
AGU
The October 2012 conviction of Italian scientists on manslaughter charges in connection with the L'Aquila earthquake was alarming to the worldwide scientific community, and the acquittal is an important step in sanctioning the role scientists play in advising governments and communicating the results of their research to the public. Scientists must be able to exchange data and information in an unfettered manner and make good-faith efforts to present the results of their research without fear of prosecution — something the original conviction threatened.

Life in Earth's primordial sea was starved for sulfate
University of British Columbia
The Earth's ancient oceans held much lower concentrations of sulfate—a key biological nutrient—than previously recognized, according to research published in Science. The findings paint a new portrait of our planet's early biosphere and primitive marine life. Organisms require sulfur as a nutrient, and it plays a central role in regulating atmospheric chemistry and global climate.

Pulling together the early solar system
MIT News
Infant planetary systems are usually nothing more than swirling disks of gas and dust. Over the course of a few million years, this gas gets sucked into the center of the disk to build a star, while the remaining dust accumulates into larger and larger chunks — the building blocks for terrestrial planets.
