One of the things that caught the attention of scientists are the glowing white spots at the bottom of the dwarf planet's Occator crater. Automatic interplanetary station was recently discovered on Ceres, the existence of seasonal processes on the planet and confirm its geological activity.

The Dawn probe has transmitted detailed photographs of the crater Okkator.

The first photo, taken on June 14 from an altitude of about 24 miles (39 kilometers) above Ceres, showcases the group of bright spots located east of Occator Crater and collectively known as Vinalia Faculae.

The US space probe dropped into its lowest and final orbit around Ceres on June 6 when it dove to 22 miles above its surface.

NASA's Dawn spacecraft has taken the best and most detailed pictures of Ceres as it maneuvered its way to a new orbit around the dwarf planet last month.

NASA's Dawn Spacecraft has seen its best performance on the odd bright spots inclining the Buddhist planet Ceres. The height at which the footage was obtained is only 35 km away. the Pictures of the mysterious stains help to determine the variability in their brightness. Scientists are wondering how they got there, suggesting they are "either from a shallow, sub-surface reservoir of mineral-laden water, or from a deeper source of brines (liquid water enriched in salts) percolating upward through fractures". The new elliptical orbit, which takes the probe from a little more than 20 miles (33 kilometers) above Ceres to a maximum distance around 2,500 miles (4,000 kilometers) will force Dawn to burn its remaining propellant faster, limiting its lifetime. Observations after the investigation showed that bright materials, which also occur in many other places around Ceres, contain sodium carbonate.

Carol Raymond, a planetary scientist at NASA's Jet Propulsion Laboratory who serves as the Dawn mission's principal investigator, said the latest spotting brings the probe's adventure at Ceres full circle.

According to NASA, researchers will employ the spacecraft's visible and infrared mapping spectrometer as well as other instruments (which include a gamma ray and neutron detector as well as a visible and infrared mapping spectrometer) to study the dwarf planet's features in greater detail.

"The first views of Ceres obtained by Dawn beckoned us with a single, blinding bright spot", she said. "While the extension of Dawn in ceras, it has been exciting to highlight the nature and history of this fascinating dwarf planet, and it is particularly appropriate that Don's final work will provide rich new data sets to test those principles". This made Dawn the first object to orbit two different bodies beyond the Earth-Moon system.

Dawn's level mission is close to the end; Last week, the space shuttle had potentially fired its acquisition ion engine.

Dawn was constructed by Orbital Sciences and is operated by JPL, which is located in Pasadena, California.
