Dawn took this image during its current orbit of Vesta, traveling from the day side to the night side. The large structure near the south pole that showed up so prominently in previous images is visible in the center of the illuminated surface. Compared to other images, this one shows more of the surface beneath the spacecraft in the shadow of night. Vesta turns on its axis once every five hours and 20 minutes. Dawn entered orbit around Vesta on July 15, 2011, and will spend a year orbiting...

NASA's Dawn spacecraft returned the first close-up image of the asteroid Vesta on Sunday. The space agency said its spacecraft became the first probe to enter orbit around an object in the main asteroid belt between Mars and Jupiter on Friday, July 15. NASA said the image shows Vesta in greater detail than ever before.  Vesta is 330 miles in diameter and the second most massive object in the asteroid belt. Dawn entered the asteroid's orbit within about 9,900 miles between the...

NASA's Dawn probe successfully entered orbit around the asteroid Vesta on Saturday, the US space agency announced in a press release early Sunday morning. It is the first spacecraft to successfully enter orbit around an object in the main asteroid belt, located between Mars and Jupiter, and will spend the next year studying the potato-shaped asteroid before departing for a dwarf planet named Ceres next July. "Today, we celebrate an incredible exploration milestone as a spacecraft enters orbit...

NASA said its Dawn probe should go into orbit around the asteroid Vesta on Friday. The satellite will spend a year at the asteroid before moving on to the "dwarf planet" Ceres. NASA said Dawn's encounter is taking place at about 117 million miles from Earth. Engineers believe the spacecraft will be captured into orbit around the asteroid on Friday and will get confirmation from Dawn on Saturday. NASA said there will be about 9,900 miles between Vesta and Dawn once the spacecraft enters...

PASADENA, Calif., July 14, 2011 /PRNewswire-USNewswire/ -- On July 15, NASA's Dawn spacecraft will begin a prolonged encounter with the asteroid Vesta, making the mission the first to enter orbit around a main-belt asteroid. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The main asteroid belt lies between the orbits of Mars and Jupiter. Dawn will study Vesta for one year, and observations will help scientists understand the earliest chapter of our solar system's history....

Hard hats will not be necessary but you may want to keep an eye on the sky. An asteroid approximately 10 to 50 yards wide will be buzzing past the Earth on Monday, The Telegraph is reporting. The tumbling space rock will be bright enough to see with a small telescope and will buzz past our planet to within 11,000 miles, well within the orbit of the moon. The asteroid, named 2011 MD, was only spotted on Wednesday by a robotic telescope in New Mexico that is exclusively used to scan the skies...

NASA's Dawn spacecraft is on track to begin the first extended visit to a large asteroid. The mission expects to go into orbit around Vesta on July 16 and begin gathering science data in early August. Vesta resides in the main asteroid belt and is thought to be the source of a large number of meteorites that fall to Earth. "The spacecraft is right on target," said Robert Mase, Dawn project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif. "We look forward to exploring this...

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

Asteroid Belt -- The Asteroid belt is a region of the solar system falling roughly between the planets Mars and Jupiter where the greatest concentration of asteroid orbits can be found. It is believed that, during the first million years of the solar system history, planets formed by accretion of planetesimals. Ripetute collisions led to the familiar rocky planets and to the gas giant's cores. However, in this zone of the system the strong gravity of Jupiter inhibited the final stages...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...
