Numerous small, bright spots appear on asteroid Vesta, as seen in this image from NASA Dawn spacecraft. This region is just north of the equator, to the west of Marcia crater.

This image from NASA Dawn spacecraft shows an interior wall and southern terrace of Marcia crater on Vesta. Relatively smooth material covers much of the terrace and has flowed downslope toward the top of the image through channels.

The interplay of bright and dark material at the rim of Marcia crater on Vesta is visible in this image mosaic taken by NASA Dawn spacecraft. The bright and dark material appear to be exposed from weathering.

This image of Marcia AV-L-12, from the atlas of the giant asteroid Vesta, was created from images taken as NASA Dawn mission flew around the object, also known as a protoplanet. The set of maps was created from mosaics of10,000 images from Dawn's framing camera instrument, taken at a low altitude of about 130 miles (210 kilometers). This map is mostly at a scale about that of regional road touring maps, where every inch of map is equivalent to a little more than 3 miles of asteroid (one centimeter equals 2 kilometers). http://photojournal.jpl.nasa.gov/catalog/PIA19516

These images from NASA Dawn spacecraft show the brightness/darkness of asteroid Vesta surface. These images are located in Vesta Marcia quadrangle.

CAPE CANAVERAL, Fla. - In the Parachute Refurbishment Facility at NASA's Kennedy Space Center, United Space Alliance senior aero composite technicians Dior Hubel (left) and Marcia Jones-Clark pack a main parachute slated for use on the Ares I-X test flight. The launch is targeted for July 2009 from Kennedy’s Launch Pad 39B and will provide an early opportunity to test and prove hardware, facilities and ground operations associated with the Ares I rocket. The Ares I-X rocket is a combination of existing and simulator hardware that will resemble the Ares I crew launch vehicle in size, shape and weight. It will provide valuable data to guide the final design of the Ares I, which will launch astronauts in the Orion crew exploration vehicle. The test flight also will bring NASA one step closer to its exploration goals of returning humans to the moon for sustained exploration of the lunar surface and missions to destinations beyond.

nside the world's largest clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., engineers worked tirelessly to install another essential part of the James Webb Space Telescope - the Near Infrared Camera into the heart of the telescope. To complete this installation, the engineers needed to carefully move NIRCam inside the heart or ISIM, or Integrated Science Instrument Module that will house all of the science instruments. &quot;Installing NIRCam into the center of the structure is nerve wracking because of the tight clearances,&quot; said Marcia J. Rieke, Professor of Astronomy at the University of Arizona, and principal investigator for the NIRCam. &quot;I'm glad nothing bumped, and all the bolts are in place.&quot; NIRCam is a unique machine because in addition to being one of the four science instruments on the Webb, it also serves as the wavefront sensor, which means it will provide vital information for shaping the telescope mirrors and aligning its optics so that they can function properly and see into the distant universe. The NIRCam instrument will operate at very cold temperatures, and will be tested to ensure that it will be able to withstand the environment of space. The NIRCam is Webb's primary imager that will cover the infrared wavelength range 0.6 to 5 microns. It will detect light from the earliest stars and galaxies in the process of formation, the population of stars in nearby galaxies, as well as young stars and exoplanets in the Milky Way. NIRCam is provided by the University of Arizona and Lockheed Martin Advanced Technology Center. Webb is an international project led by NASA with its partners the European Space Agency and the Canadian Space Agency. The James Webb Space Telescope is the successor to NASA's Hubble Space Telescope. It will be the most powerful space telescope ever built.
