Strange celestial event happened last weekend in the Sverdlovsk region. First, the sky turned red, and then lit up with a bright yellow light. Celestial phenomena have not been able to comment on any of the Sverdlovsk forecasters Hydrometcenter nor representatives Kourovka Observatory. Best phenomenon was seen in the sky over the city Rezhom.
Странное небесное явление произошло в минувшие выходные в Свердловской области. Сначала небо покраснело, а затем озарилось ярким желтым светом. Небесное явление прокомментировать пока не смогли ни синоптики Свердловского Гидрометцентра, ни представители Коуровской обсерватории. Лучше всего явление было видно в небе над городом Режом.

MOST IMPORTANT VIDEO showing explosion from ground and not from meteor!
Вспышка над Свердловской областью | Explosion in the Sverdlovsk region, Russia
Posted to YouTube by IrSCr 6,098 views

Expert opinion-
  Hmmm. I doubt this one is a meteor.
From the video, it appears that the person shooting it was already starting to pay attention well before the peak event. In the video, you can see a pulsating red glow in a stationary position well before it becomes very bright, the latter only happening 18 seconds in the video. The bright peak, of several seconds duration, also seems to be quite stationary. So the event, whatever it was, was already going on for at least 18 seconds, and it does not seem to be moving during that time.
  My guess this is something originating on Earth. To me, it looks like a fire or series of small explosions and subsequent large explosion or flash fire reflecting on a cloud deck. The Russian article (in Google translation) seems to suggest there is a major chemical plant nearby? I wonder if any explosions were heard some tens of seconds after the movie ends.

Geologic Maps of Vesta from NASA's Dawn Mission Published

Credit: NASA/JPL-Caltech/ASU
This high-resolution geological map of Vesta is derived from Dawn spacecraft data. Brown colors represent the oldest, most heavily cratered surface. Purple colors in the north and light blue represent terrains modified by the Veneneia and Rheasilvia impacts, respectively. Light purples and dark blue colors below the equator represent the interior of the Rheasilvia and Veneneia basins. Greens and yellows represent relatively young landslides or other downhill movement and crater impact materials, respectively. This map unifies 15 individual quadrangle maps published this week in a special issue of Icarus. Map is a Mollweide projection, centered on 180 degrees longitude using the Dawn Claudia coordinate system.

JPL manages the Dawn mission for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. The University of California at Los Angeles (UCLA) is responsible for overall Dawn mission science. Orbital Sciences Corp. in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, the Max Planck Institute for Solar System Research, the Italian Space Agency and the Italian National Astrophysical Institute are international partners on the mission team.

Vesta Topography Map
This color-coded topography map from NASA's Dawn mission shows the giant asteroid Vesta in an equirectangular projection at 32 pixels per degree, relative to an ellipsoid of 177 miles by 177 miles by 142 miles (285 kilometers by 285 kilometers by 229 kilometers). The color scale extends from 13.96 miles (22.47 kilometers) below the surface in purple to 12.11 miles (19.48 kilometers) above the surface in white. The topographic map was constructed from analyzing more than 17,000 images from Dawn's framing camera that were taken with varying sun and viewing angles.

The Dawn mission to Vesta and Ceres is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, for NASA's Science Mission Directorate, Washington. The University of California, Los Angeles, is responsible for overall Dawn mission science. The Dawn framing cameras were developed and built under the leadership of the Max Planck Institute for Solar System Research, Katlenburg-Lindau, Germany, with significant contributions by DLR German Aerospace Center, Institute of Planetary Research, Berlin, and in coordination with the Institute of Computer and Communication Network Engineering, Braunschweig. The framing camera project is funded by the Max Planck Society, DLR and NASA.

NOVEMBER 17, 2014
Geologic Maps of Vesta from NASA's Dawn Mission Published

Images from NASA's Dawn Mission have been used to create a series of high-resolution geological maps of the large asteroid Vesta, revealing the variety of surface features in unprecedented detail. These maps are included with a series of 11 scientific papers published this week in a special issue of the journal Icarus.

Geological mapping is a technique used to derive the geologic history of a planetary object from detailed analysis of surface morphology, topography, color and brightness information. A team of 14 scientists mapped the surface of Vesta using Dawn spacecraft data, led by three NASA-funded participating scientists: David A. Williams of Arizona State University, Tempe; R. Aileen Yingst of the Planetary Science Institute, Tucson, Arizona; and W. Brent Garry of the NASA Goddard Spaceflight Center, Greenbelt, Maryland.

"The geologic mapping campaign at Vesta took about two-and-a-half years to complete, and the resulting maps enabled us to recognize a geologic timescale of Vesta for comparison to other planets," said Williams.

Scientists discovered through these maps that impacts from several large meteorites have shaped Vesta's history. Asteroids like Vesta are remnants of the formation of the solar system, giving scientists a peek at its history. Asteroids could also harbor molecules that are the building blocks of life and reveal clues about the origins of life on Earth.

The geologic mapping of Vesta is enabled by images obtained by the framing camera provided by the Max Planck Institute for Solar System Research of the German Max Planck Society and the German Aerospace Center. This camera takes panchromatic images and seven bands of color-filtered images. Stereo photos are used to create topographic models of the surface that aid in the geologic interpretation.

Vesta's geologic timescale is determined by the sequence of large impact events, primarily by the Veneneia and Rheasilvia impacts in Vesta's early history and the Marcia impact in its late history. The oldest crust on Vesta pre-dates the Veneneia impact.The relative timescale is supplemented by model-based absolute ages from two different approaches that apply crater statistics to date the surface.

"This mapping was crucial for getting a better understanding of Vesta's geological history, as well as providing context for the compositional information that we received from other instruments on the spacecraft: the visible and infrared (VIR) mapping spectrometer and the gamma-ray and neutron detector (GRaND)," said Carol Raymond, Dawn's deputy principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California.

The objective of NASA's Dawn mission is to characterize the two most massive objects in the main asteroid belt between Mars and Jupiter - Vesta and the dwarf planet Ceres. The spacecraft launched in 2007. Vesta, orbited by the Dawn spacecraft between July 2011 and September 2012, was thought to be the source of a unique set of basaltic meteorites (called HEDs, for howardite-eucrite-diogenite), and Dawn confirmed the Vesta-HED connection.

The Dawn spacecraft is currently on its way to Ceres, the largest object in the asteroid belt. Dawn will arrive at Ceres in March 2015.

Dawn uses ion propulsion in spiraling trajectories to travel from Earth to Vesta, orbit Vesta and then continue on to orbit the dwarf planet Ceres. Ion engines use very small amounts of onboard fuel, enabling a mission that would be unaffordable or impossible without them.

JPL manages the Dawn mission for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. The University of California at Los Angeles (UCLA) is responsible for overall Dawn mission science. Orbital Sciences Corp. in Dulles, Virginia, designed and built the spacecraft.
