049-Vesta-PIA14124.jpg4-Vesta in Spectrometer View (Visible Light and IR)76 visiteCaption NASA:"On June 8, 2011, the Visible and InfraRed Mapping Spectrometer aboard NASA's Dawn Spacecraft captured the instrument's first images of 4-Vesta that are larger than a few pixels, from a distance of about 218.000 miles (approx. 351.000 Km). The images were taken for calibration purposes.
Images obtained in the Visible part of the light Spectrum, at about 0,55 microns in wavelength, appear on the left. Images obtained in the InfraRed Spectrum, at around 3 microns in wavelength, appear on the right. The spatial resolution of these images is about 60 miles (approx. 90 Km) per pixel.
The Visible and InfraRed mapping spectrometer will be able to provide images of 4-Vesta in 432 wavelengths, which will help scientists determine the basic composition of the Asteroid".MareKromium

053-Vesta-PIA14312.jpgFeatures of 4- Vesta (Saturated Absolute Natural Colors; credits for the additional process. and color: Dr Paolo C. Fienga - Lunexit Team)212 visiteCaption NASA:"NASA's Dawn Spacecraft obtained this image of the giant Asteroid 4-Vesta with its framing camera on July, 9, 2011. It was taken from a distance of about 26.000 miles (approx. 41.000 Km). 4-Vesta is also considered a "protoplanet" because it is a large body that almost became a planet. Each pixel in the image corresponds to roughly 2,4 miles (about 3,8 Km).
The Dawn mission to 4-Vesta and 1-Ceres is managed by the Jet Propulsion Laboratory, for NASA's Science Mission Directorate, Washington, D.C. It is a project of the Discovery Program managed by NASA's Marshall Space Flight Center, Huntsville, Ala. UCLA, is responsible for overall Dawn mission science. Orbital Sciences Corporation of Dulles, Va., designed and built the Dawn Spacecraft!".

Fienga - Lunar Explorer Italia)133 visiteCaption NASA:"NASA's Dawn Spacecraft obtained this image with its framing camera on July 17, 2011. It was taken from a distance of about 9500 miles (approx. 15.000 Km) away from the Protoplanet 4-Vesta. Each pixel in the image corresponds to roughly 0,88 miles (about 1,4 Km)".MareKromium

055-Vesta-PIA14315.jpgThe South Pole of 4-Vesta111 visiteCaption NASA:"This image, taken by the framing camera instrument aboard NASA's Dawn Spacecraft, shows the South Polar Region of 4-Vesta, which has a diameter of about 330 miles (approx. 530 Km). The image was taken through the clear filter on July, 9th, 2011, as part of a rotation characterization sequence, and it has a scale of about 2,2 miles (approx. 3,5 Km) per pixel.
To enhance details, the resolution was enlarged to .6 miles (roughly 1 Km) per pixel.
This Region is characterized by rough topography, a large Mountain, Impact Craters, Grooves and steep Scarps. The original image was map-projected, centered at 55°
South Latitude and 210° East Longitude".MareKromium

060-Vesta_and_Friends-PIA14316.jpg4-Vesta and "Friends"...88 visiteCaption NASA:"This composite image shows the comparative sizes of 8 (eight) Asteroids. Up until now, Lutetia, with a diameter of about 81 miles (approx. 130 Km), was the largest Asteroid visited by a Spacecraft.
Vesta, which is also considered a protoplanet because it's a large body that almost became a planet, dwarfs all other small bodies in this image, with its diameter sizing up at approximately 330 miles (about 530 Km)".
