Managing Orbital Debris and Space Traffic
Bethesda MD (SPX) Sep 25, 2014
Those familiar with air traffic management architectures understand the constraints of aircraft flying in the atmosphere, vehicle dynamics and command and control techniques. Unfortunately, compared to air traffic, space traffic has many more degrees of freedom and much less control capability. Add to this the completely uncontrolled nature of space debris and the reality that most debris objects cannot be tracked and motion cannot be accurately measured or simulated. In fact, orbiting debris is a ... read more

Infant solar system shows signs of windy weather Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around a T Tauri star, an infant analog of our own Sun. This ... more		Finding hints of gravitational waves in the stars Scientists have shown how gravitational waves-invisible ripples in the fabric of space and time that propagate through the universe-might be "seen" by looking at the stars. The new model proposes th ... more		CME Week: The Difference Between Flares and CMEs There are many kinds of eruptions on the sun. Solar flares and coronal mass ejections both involve gigantic explosions of energy, but are otherwise quite different. The two phenomena do sometimes oc ... more
				Particle detector finds hints of dark matter in space Researchers at MIT's Laboratory for Nuclear Science have released new measurements that promise to shed light on the origin of dark matter. The MIT group leads an international collaboration o ... more		Distant planet's atmosphere shows evidence of water vapor A Neptune-sized exoplanet, which lies some 729 trillion miles away (122 light-years), has water vapor in its atmosphere. While it's a promising sign for astronomers in search of distant life, exoplanet HAT-P-11b with its water-filled atmosphere is not the kind of place you'd want to live - or where anything could live. ... more

Asteroid named for University of Utah makes public debut What's rocky, about a mile wide, orbits between Mars and Jupiter and poses no threat to Earth? An asteroid named "Univofutah" after the University of Utah. Discovered on Sept. 8, 2008, by long ... more		Russia to Launch Full-Scale Moon Exploration Next Decade Russia's space agency Roscosmos plans to launch a full-scale Moon exploration program in late 2020s or early 2030s, the agency's head Oleg Ostapenko said on Tuesday. "We are planning to comple ... more		India signs $7 bn deal for 97 domestically made fighter jets France doubles down on threat to build future fighter jet alone US approves $1.2 bn missile sale to Germany		Magnetic fields make the excitons go 'round A major limitation in the performance of solar cells happens within the photovoltaic material itself: When photons strike the molecules of a solar cell, they transfer their energy, producing quasi-p ... more
				New 'star' shaped molecule breakthrough Scientists at The University of Manchester have generated a new star-shaped molecule made up of interlocking rings, which is the most complex of its kind ever created. Known as a 'Star of Davi ... more		Penn research helps uncover mechanism behind solid-solid phase transitions Two solids made of the same elements but with different geometric arrangements of the atoms, or crystal phases, can produce materials with different properties. Coal and diamond offer a spectacular ... more

Uncovering the forbidden side of molecules Researchers at the University of Basel in Switzerland have succeeded in observing the "forbidden" infrared spectrum of a charged molecule for the first time. These extremely weak spectra offer ... more		Chemical bond between a superheavy element and a carbon atom established An international collaboration led by research groups from Mainz and Darmstadt has achieved the synthesis of a new class of chemical compounds for superheavy elements at the RIKEN Nishina Center for ... more		Simulations of Exoplanet Formation May Help Inform Search for Extraterrestrial Life Ancient hot springs reveal how microbes thrived before Earth gained oxygen Framework proposed to study planetary scale impact of life		Mystery of rare 5-hour space explosion explained Next week in St. Petersburg, Russia, scientists on an international team that includes Penn State University astronomers will present a paper that provides a simple explanation for mysterious ultra- ... more
Big surprises can come in small packages Astronomers using the NASA/ESA Hubble Space Telescope have found a monster lurking in a very unlikely place.

But as galaxies age and grow more massive over time, their ability to create their own stars wanes, and they are forced to add on mass by swallowing up other smaller galaxies. ... more

	What is life? It's a Tricky, Often Confusing Question What is life? This is a question that is often asked and typically confused. The confusion starts from the several uses of the word "life" in English. There are at least three usages as exemplified ... more		Monster galaxies gain weight by eating smaller neighbours Massive galaxies in the Universe have stopped making their own stars and are instead snacking on nearby galaxies, according to research by Australian scientists. Astronomers looked at more tha ... more
