A small satellite designed and built by a team of University of Colorado Boulder students to better understand how atmospheric drag can affect satellite orbits was successfully launched from Vandenberg Air Force Base in California Sunday morning. The satellite, known as the Drag and Atmospheric Neutral Density Explorer satellite, or DANDE, will investigate how a layer of Earth鈥檚 atmosphere known as the thermosphere varies in density at altitudes from about 200 to 300 miles above Earth. The commercial Falcon-9 SpaceX rocket lifted off the launch pad at about 10 a.m. MDT carrying DANDE, a small beach ball-sized satellite developed over a period of about six years by roughly 150 students, primarily undergraduates, as part of the Colorado Space Grant Consortium, or COSGS.

A pair of breakthroughs in the field of silicon photonics by researchers at the University of Colorado Boulder, the Massachusetts Institute of Technology and Micron Technology Inc. could allow for the trajectory of exponential improvement in microprocessors that began nearly half a century ago鈥攌nown as Moore鈥檚 Law鈥攖o continue well into the future, allowing for increasingly faster electronics, from supercomputers to laptops to smartphones.

The University of Colorado Boulder will host a conference that explores the phenomenon of slavery from a global, historical perspective on Sept. 27-28. The event will include scholars specializing in the study of slavery in ancient, medieval and modern contexts and in global regions that include Western, pre-Columbian, African, Asian and Muslim. Titled 鈥淲hat is a Slave Society: an International Conference on the Nature of Slavery as a Global Historical Phenomenon,鈥� the event will be held in the British and Irish Studies room of Norlin Library.

An intriguing study led by the University of Colorado Boulder may provide a powerful new tool in the quiver of forensic scientists attempting to determine the time of death in cases involving human corpses: a microbial clock.
