- The European Space Agency has announced that two of 31 mission proposals have been chosen for additional development funding. The CarbonSat mission would quantify and monitor the distribution of two of the most important greenhouse gases in the atmosphere, also released through human activity: carbon dioxide and methane. Data from the mission would lead to a better understanding of the sources and sinks of these two gases and how they are linked to climate change. The FLEX mission aims to provide global maps of vegetation fluorescence, which can be converted into an indicator of photosynthetic activity. These data would improve our understanding of how much carbon is stored in plants and their role in the carbon and water cycles.

- A new study from Galaxy Zoo’s second crowd-sourced scientific effort, buoys the idea that galaxies with central bars somehow encourage the formation of big, blue and short-lived stars, and funnel gas and dust to supermassive black holes lurking at their cores. In the process, bars may quickly consume star-making materials to leave behind only a “dead” galaxy of red and fading stars.
- The NASA Hubble Space Telescope has returned an image of a wandering cloud of gas and dust from an area of the well-known Pleiades star cluster. Starlight from Merope is slowly destroying the small nebula.

- China unveiled an image of the Bay of Rainbows taken by the lunar orbiter Chang’e-2 from a designed altitude of 18.7 kilometers. The image was taken on 28 October, and covers the area that China plans to land its next mission.
- A new theoretical model of Solar coronal mass ejections (CMEs) will be presented at the 52nd Annual Meeting of the APS Plasma Physics Division. The Sun sporadically expels trillions of tons of million-degree hydrogen gas during a CME. Such clouds are enormous in size (spanning millions of miles) and are made up of magnetized plasma gases, so hot that hydrogen atoms are ionized. CMEs are rapidly accelerated by magnetic forces to speeds of hundreds of kilometers per second to upwards of 2,000 kilometers per second in several tens of minutes. CMEs are closely related to solar flares and, when they impinge on the Earth, can trigger spectacular auroral displays. They also induce strong electric currents in the Earth’s plasma atmosphere (i.e., the magnetosphere and ionosphere), leading to outages in telecommunications and GPS systems and even the collapse of electric power grids if the disturbances are very severe.

- Super Earths may be hostile to life, suggests a New Scientist article. “Rocky planets a few times heavier than Earth that we thought might be life-friendly may lack one vital feature: a protective magnetic field. Planets are thought to owe their magnetic fields to an iron core that is at least partly molten. But a simulation of super-Earths between a few times and 10 times Earth’s mass suggests that high pressures will keep the core solid, according to Guillaume Morard of the Institute of Mineralogy and Physics of Condensed Matter in Paris, France, and his team (arxiv.org/1010.5133).”

- Discovery was making her first real attempt to launch on Friday, as the loading of her External Tank (ET-137) picked up following approval by the Mission Management Team (MMT). Tanking had been nominal until a leak was detected on the Ground Umbilical Carrier Plate (GUCP) – causing managers to carry out testing prior to detanking – ultimately leading to a delay to November 30.
- At 8:20 PM Phoenix time, the ULA team successfully launched the fourth COSMO-SkyMed satellite for Boeing, the Italian Space Agency, Ministry of Defence and Thales Alenia Space. The ULA Delta II 7420-10 configuration vehicle used a ULA first stage booster powered by a Pratt & Whitney Rocketdyne RS-27A main engine and four Alliant Techsystems (ATK) strap-on solid rocket boosters. An Aerojet AJ10-118K engine powered the second stage. The payload was encased by a 10-foot-diameter composite payload fairing. COSMO-SkyMed 4 is the final satellite in the initial constellation for this system. Each of the four satellites is equipped with a high-resolution Synthetic Aperture Radar operating in X-band.
