The Soyuz rocket is rolled out to the launch pad by train on Monday, Sept. 23, 2013, at the Baikonur Cosmodrome in Kazakhstan. Launch of the Soyuz rocket is scheduled for September 26 and will send Expedition 37 Soyuz Commander Oleg Kotov, NASA Flight Engineer Michael Hopkins and Russian Flight Engineer Sergei Ryazansky on a five and a half-month mission aboard the International Space Station.

Here’s an image from Sept. 22 of Typhoon Usagi battering the China coast, nearing landfall. Usagi was closing in on the coast of southeastern China where it is poised to make landfall north of Hong Kong. Maximum sustained winds are near 95 knots. At that time, the center of this large storm was near 22.6 north and 116.2 east, about 144 nautical miles east of Hong Kong, but the effects of the storm are already being felt along the coast. Usagi was moving to west-northwest at 12 knots and generating very high, rough seas of up to 42 feet. Coastal areas of southeastern China, and southwestern Taiwan can expect very rough surf as Usagi makes landfall. Satellite data yesterday, Sept. 22, shows that Usagi's eye is about 10 nautical miles wide. NASA's Tropical Rainfall Measuring Mission, or TRMM, satellite passed overhead yesterday at 5:23 a.m. EDT as it was making landfall, and saw very heavy rainfall in the southern quadrant of the storm. Rains were falling at over 50 mm/2 inches per hour. TRMM's Precipitation Radar can provide 3-D vertical profiles of rain and snow from the surface up to a height of about 12 miles/20 kilometers.

This new Hubble Space Telescope image shows the star HD 184738, also known as Campbell’s hydrogen star. It is surrounded by plumes of reddish gas — the fiery red and orange hues are caused by glowing gases, including hydrogen and nitrogen. HD 184738 is at the center of a small planetary nebula. The star itself is known as a [WC] star, a rare class resembling their much more massive counterparts — Wolf-Rayet stars. These stars are named after two French astronomers, Charles Wolf and Georges Rayet, who first identified them in the mid-nineteenth century. Wolf-Rayet stars are hot stars, perhaps 20 times more massive than the sun, that are rapidly blowing away material and losing mass. [WC] stars are rather different: they are low-mass sun-like stars at the end of their lives. While these stars have recently ejected much of their original mass, the hot stellar core is still losing mass at a high rate, creating a hot wind. It is these winds that cause them to resemble Wolf-Rayet stars.However, astronomers can look more closely at the composition of these winds to tell the stars apart; [WC] stars are identified by the carbon and oxygen in their winds. Some true Wolf-Rayet stars are rich in nitrogen instead, but this is very rare among their low-mass counterparts. HD 184738 is also very bright in the infrared part of the spectrum, and is surrounded by dust very similar to the material that the Earth formed from. The origin of this dust is uncertain.

This summer's sea ice minimum in the Arctic is still the sixth lowest extent of the satellite record and is 432,000 square miles (1.12 million square kilometers) lower than the 1981-2010 average, roughly the size of Texas and California combined. The ice cap covering the Arctic Ocean shrinks and expands with the passing of the seasons, melting in the summer and refreezing during the long, frigid Arctic winter. This year, cooler weather in the spring and summer led to a late start of the melt season and overall less melt. This animation shows the daily Arctic sea ice extent and seasonal land cover change through Sept. 12, 2013, the day before NSIDC estimated that sea ice reached its minimum area of extent. The data was provided by the Japan Aerospace Exploration Agency from their AMSR2 instrument aboard the GCOM-W1 satellite. This year, Arctic temperatures were 1.8 to 4.5 degrees Fahrenheit (1 to 2.5 degrees Celsius) lower than average, according to NASA's Modern Era Retrospective analysis for Research and Applications, a merging of observations and a modeled forecast. The colder temperatures were in part due to a series of summer cyclones. In August 2012, a big storm caused havoc on the Arctic Ocean’s icy cover, but this summer’s cyclones have had the opposite effect: under cloudier conditions, surface winds spread the ice over a larger area.

Enormous arms of hot gas have been discovered in the Coma cluster of galaxies by using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. These features, which span at least half a million light years, provide insight into how the Coma cluster has grown through mergers of smaller groups and clusters of galaxies to become one of the largest structures in the universe held together by gravity. A new composite image, with Chandra data in pink and optical data from the Sloan Digital Sky Survey appearing in white and blue, features these spectacular arms. In this image, the Chandra data have been processed so extra detail can be seen. The X-ray emission is from multimillion-degree gas and the optical data shows galaxies in the Coma Cluster, which contain only about one-sixth the mass in hot gas. Only the brightest X-ray emission is shown here, to emphasize the arms, but the hot gas is present over the entire field of view. Researchers think that these arms were most likely formed when smaller galaxy clusters had their gas stripped away by the head wind created by the motion of the cluster through the hot gas, in much the same way that the headwind created by a roller coaster blows the hats off riders.

Aboard the International Space Station, NASA astronaut Karen Nyberg caught the reflection of Earth's horizon on the station’s solar arrays at sunset on Sept. 18. The space station is a convergence of science, technology and human innovation that demonstrates new technologies and makes research breakthroughs not possible on Earth. The space station has had continuous human occupation since November 2000. In that time it has been visited by more than 200 people and a variety of international and commercial spacecraft. The space station remains the springboard to NASA's next great leap in exploration, including future missions to an asteroid and Mars.
