NASA - National Aeronautics and Space AdministrationPasadena, CA – The two brightest spots on dwarf planet Ceres, which have fascinated scientists for months, are back in view in the newest images from NASA’s Dawn spacecraft. Dawn took these images on April 14th and 15th from a vantage point 14,000 miles (22,000 kilometers) above Ceres’ north pole.

The images show the brightest spot and its companion clearly standing out against their darker surroundings, but their composition and sources are still un-known. Scientists also see other interesting features, including heavy cratering. As Dawn gets closer to Ceres, surface features will continue to emerge at in-creasingly better resolution.

NASA - National Aeronautics and Space AdministrationPasadena, CA – After spending more than a month in orbit on the dark side of dwarf planet Ceres, NASA’s Dawn spacecraft has captured several views of the sunlit north pole of this intriguing world. These images were taken on April 10th from a distance of 21,000 miles (33,000 kilometers), and they represent the highest-resolution views of Ceres to date.

Subsequent images of Ceres will show surface features at increasingly better resolution.

NASA’s Dawn spacecraft creates Color Map of dwarf planet Ceres revealing a surface full of variety

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – A new color map of dwarf planet Ceres, which NASA’s Dawn spacecraft has been orbiting since March, reveals the diversity of the surface of this planetary body. Differences in morphology and color across the surface suggest Ceres was once an active body, Dawn researchers said today at the 2015 General Assembly of the European Geosciences Union in Vienna.

“This dwarf planet was not just an inert rock throughout its history. It was active, with processes that resulted in different materials in different regions. We are beginning to capture that diversity in our color images,” said Chris Russell, principal investigator for the Dawn mission, based at the University of California, Los Angeles.

This map-projected view of Ceres was created from images taken by NASA's Dawn spacecraft during its initial approach to the dwarf planet, prior to being captured into orbit in March 2015. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

NASA - National Aeronautics and Space AdministrationPasadena, CA – Millions of images of celestial objects, including asteroids, observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft now are available online to the public. The data was collected following the restart of the asteroid-seeking spacecraft in December 2013 after a lengthy hibernation.

The collection of millions of infrared images and billions of infrared measurements of asteroids, stars, galaxies and quasars spans data obtained between December 13th, 2013, and December 13th, 2014.

NASA announces details for its Asteroid Redirect Mission; Next Steps towards Mars

 

Written by David E. Steitz
NASA Headquarters

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA Wednesday announced more details in its plan for its Asteroid Redirect Mission (ARM), which in the mid-2020s will test a number of new capabilities needed for future human expeditions to deep space, including to Mars. NASA also announced it has increased the detection of near-Earth Asteroids by 65 percent since launching its asteroid initiative three years ago.

For ARM, a robotic spacecraft will capture a boulder from the surface of a near-Earth asteroid and move it into a stable orbit around the moon for exploration by astronauts, all in support of advancing the nation’s journey to Mars.

NASA’s Dawn spacecraft makes history as it begins orbit around Dwarf Planet Ceres

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 38,000 miles (61,000 kilometers) from Ceres when it was captured by the dwarf planet’s gravity at about 4:39am PST (7:39am EST) Friday.

Mission controllers at NASA’s Jet Propulsion Laboratory in Pasadena, California received a signal from the spacecraft at 5:36am PST (8:36am EST) that Dawn was healthy and thrusting with its ion engine, the indicator Dawn had entered orbit as planned.

NASA’s Dawn spacecraft’s latest photo reveals bright spot on dwarf planet Ceres has second bright area nearby

 

Written by Elizabeth Landau
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Dwarf planet Ceres continues to puzzle scientists as NASA’s Dawn spacecraft gets closer to being captured into orbit around the object. The latest images from Dawn, taken nearly 29,000 miles (46,000 kilometers) from Ceres, reveal that a bright spot that stands out in previous images lies close to yet another bright area.

“Ceres’ bright spot can now be seen to have a companion of lesser brightness, but apparently in the same basin. This may be pointing to a volcano-like origin of the spots, but we will have to wait for better resolution before we can make such geologic interpretations,” said Chris Russell, principal investigator for the Dawn mission, based at the University of California, Los Angeles.

This image was taken by NASA's Dawn spacecraft of dwarf planet Ceres on Feb. 19 from a distance of nearly 29,000 miles (46,000 kilometers). It shows that the brightest spot on Ceres has a dimmer companion, which apparently lies in the same basin. (NASA/JPL-Caltech/UCLA/MPS/DLR/IDA)

NASA Astronauts to conduct Spacewalks to ready International Space Station for Commercial Transport Ships

 

Written by Anna Seils
NASA

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Change is on the horizon for the International Space Station as three upcoming spacewalks prepare the orbiting laboratory for future arrivals by U.S. commercial crew spacecraft.

The spacewalks are designed to lay cables along the forward end of the U.S. segment to bring power and communication to two International Docking Adapters slated to arrive later this year. The new docking ports will welcome U.S. commercial spacecraft launching from Florida beginning in 2017, permitting the standard station crew size to grow from six to seven and potentially double the amount of crew time devoted to research.

NASA’s Deep Space Network antenna image shows Asteroid passing Earth today had it’s own Moon

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Scientists working with NASA’s 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, California, have released the first radar images of asteroid 2004 BL86. The images show the asteroid, which made its closest approach today (January 26th, 2015) at 8:19am PST (10:19am CST) at a distance of about 745,000 miles (1.2 million kilometers, or 3.1 times the distance from Earth to the moon), has its own small moon.

The 20 individual images used in the movie were generated from data collected at Goldstone on January 26th, 2015. They show the primary body is approximately 1,100 feet (325 meters) across and has a small moon approximately 230 feet (70 meters) across.

NASA’s Near Earth Object Program reports Asteroid to Safely Fly By on January 26th, 2015

 

Written by DC Agle
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – An asteroid, designated 2004 BL86, will safely pass about three times the distance of Earth to the moon on January 26th. From its reflected brightness, astronomers estimate that the asteroid is about a third of a mile (0.5 kilometers) in size.

The flyby of 2004 BL86 will be the closest by any known space rock this large until asteroid 1999 AN10 flies past Earth in 2027.

At the time of its closest approach on January 26th, the asteroid will be approximately 745,000 miles (1.2 million kilometers) from Earth.

This graphic depicts the passage of asteroid 2004 BL86, which will come no closer than about three times the distance from Earth to the moon on Jan. 26th, 2015. Due to its orbit around the sun, the asteroid is currently only visible by astronomers with large telescopes who are located in the southern hemisphere. But by Jan. 26th, the space rock's changing position will make it visible to those in the northern hemisphere. (NASA/JPL-Caltech)
