As the spacecraft spirals into closer and closer orbits around the dwarf planet, researchers will be looking for signs that these strange features are changing, which would suggest current geological activity.<\/p>\n<p>\u201cStudying Ceres allows us to do historical research in space, opening a window into the earliest chapter in the history of our solar system,\u201d said Jim Green, director of NASA\u2019s Planetary Science Division at the agency\u2019s Headquarters in Washington. \u201cData returned from Dawn could contribute significant breakthroughs in our understanding of how the solar system formed.\u201d<\/p>\n<p>Dawn began its final approach phase toward Ceres in December. The spacecraft has taken several optical navigation images and made two rotation characterizations, allowing Ceres to be observed through its full nine-hour rotation. Since Jan. 25, Dawn has been delivering the highest-resolution images of Ceres ever captured, and they will continue to improve in quality as the spacecraft approaches.<\/p>\n<p>Sicilian astronomer Father Giuseppe Piazzi spotted Ceres in 1801. As more such objects were found in the same region, they became known as asteroids, or minor planets. Ceres was initially classified as a planet and later called an asteroid. In recognition of its planet-like qualities, Ceres was designated a dwarf planet in 2006, along with Pluto and Eris.<\/p>\n<p><a href=\"http:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/03\/15-027-dawn-ceres1.jpg\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"10037\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=10037\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/03\/15-027-dawn-ceres1.jpg\" data-orig-size=\"648,349\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"15-027-dawn-ceres[1]\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/03\/15-027-dawn-ceres1.jpg\" class=\"aligncenter wp-image-10037\" src=\"http:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/03\/15-027-dawn-ceres1.jpg\" alt=\"15-027-dawn-ceres[1]\" width=\"520\" height=\"280\" srcset=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/03\/15-027-dawn-ceres1.jpg 648w, https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/03\/15-027-dawn-ceres1-300x162.jpg 300w\" sizes=\"auto, (max-width: 520px) 100vw, 520px\" \/><\/a><\/p>\n<p style=\"padding-left: 30px;\"><em>NASA&#8217;s Dawn spacecraft took these images of dwarf planet Ceres from about 25,000 miles (40,000 kilometers) away on Feb. 25, 2015. Ceres appears half in shadow because of the current position of the spacecraft relative to the dwarf planet and the sun. The resolution is about 2.3 miles (3.7 kilometers) per pixel.\u00a0Image Credit:\u00a0NASA\/JPL-Caltech\/UCLA\/MPS\/DLR\/IDA<\/em><\/p>\n<p>Ceres is named for the Roman goddess of agriculture and harvests. Craters on Ceres will similarly be named for gods and goddesses of agriculture and vegetation from world mythology. Other features will be named for agricultural festivals.<\/p>\n<p>Launched in September 2007, Dawn explored the giant asteroid Vesta for 14 months in 2011 and 2012, capturing detailed images and data about that body. Both Vesta and Ceres orbit the sun between Mars and Jupiter, in the main asteroid belt. This two-stop tour of our solar system is made possible by Dawn\u2019s ion propulsion system, its three ion engines being much more efficient than chemical propulsion.<\/p>\n<p>&#8220;Both Vesta and Ceres were on their way to becoming planets, but their development was interrupted by the gravity of Jupiter,\u201d said Carol Raymond, deputy project scientist at JPL. \u201cThese two bodies are like fossils from the dawn of the solar system, and they shed light on its origins.&#8221;<\/p>\n<p>Ceres and Vesta have several important differences. Ceres is the most massive body in the asteroid belt, with an average diameter of 590 miles (950 kilometers). Ceres&#8217; surface covers about 38 percent of the area of the continental United States. Vesta has an average diameter of 326 miles (525 kilometers), and is the second most massive body in the belt. The asteroid formed earlier than Ceres and is a very dry body. Ceres, in contrast, is estimated to be 25 percent water by mass.<\/p>\n<p>&#8220;By studying Vesta and Ceres, we will gain a better understanding of the formation of our solar system, especially the terrestrial planets and most importantly the Earth,&#8221; said Raymond. &#8220;These bodies are samples of the building blocks that have formed Venus, Earth and Mars. Vesta-like bodies are believed to have contributed heavily to the core of our planet, and Ceres-like bodies may have provided our water.&#8221;<\/p>\n<p>&#8220;We would not be able to orbit and explore these two worlds without ion propulsion,\u201d Mase said. \u201cDawn capitalizes on this innovative technology to deliver big science on a small budget.\u201d<\/p>\n<p>In addition to the Dawn mission, NASA will launch in 2016 its Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) spacecraft. This mission will study a large asteroid in unprecedented detail and return samples to Earth.<\/p>\n<p>NASA also places a high priority on tracking and protecting Earth from asteroids. NASA&#8217;s Near-Earth Object (NEO) Program at the agency\u2019s headquarters manages and funds the search, study and monitoring of asteroids and comets whose orbits periodically bring them close to Earth. NASA is pursuing an Asteroid Redirect Mission (ARM), which will identify, redirect and send astronauts to explore an asteroid. Among its many exploration goals, the mission could demonstrate basic planetary defense techniques for asteroid deflection.<\/p>\n<p>Dawn&#8217;s mission is managed by JPL for NASA&#8217;s Science Mission Directorate in Washington. Dawn is a project of the directorate&#8217;s Discovery Program, managed by NASA&#8217;s Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science.
