NASA’s Dawn, Historic First Mission to Dwarf Planet Ceres, Achieves Orbit

Newest image of Ceres from Dawn Ceres is seen from NASA’s Dawn spacecraft on March 1, just a few days before the mission achieved orbit around the previously unexplored dwarf planet. The image was taken at a distance of about 30,000 miles (about 48,000 kilometers). Image Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

NASA’s Dawn spacecraft became humanity’s first […]

Landing Region Chosen for InSight at T-Minus One Year to Red Planet Launch

In the weeks after NASA’s InSight mission reaches Mars in September 2016, the lander’s arm will lift two science instruments off the deck and place them onto the ground. This image shows testing of InSight’s robotic arm at JPL about two years before it will perform these tasks on Mars. Credit: NASA/JPL-Caltech

At T-minus […]

Ceres Reveals Eye-Like Bright Spots, Mr. Spock Explains Dawn

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. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

A scientific mystery on dwarf planet Ceres—worthy of investigation […]

Ceres Shows Mystifying Faces and Perplexing White Spots to NASA’s Dawn

Two mystifying faces of Ceres These two views of Ceres were acquired by NASA’s Dawn spacecraft on Feb. 12, 2015, from a distance of about 52,000 miles (83,000 kilometers) as the dwarf planet rotated. The images have been magnified from their original size. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

Rosetta’s Valentine’s Day Flyby Encounter Produces Stunning Comet Close-Ups

Backside view of Comet 67P/Churyumov-Gerasimenko Four image mosaic of Comet 67P/Churyumov-Gerasimenko comprising images taken on 14 February 2015 at 10:15 GMT just prior to closest approach from a distance of 12.6 km from the comet centre (about 10.6 km from the surface). For the comet centre distance, the image scale is 1.1 m/pixel. In […]

Rosetta Captures Spectacular Comet Jets Blasting Away Ahead of Valentine’s Day Encounter

Comet 67P/Churyumov-Gerasimenko belching gas and dust This four-image mosaic comprises images taken from a distance of 28.7 km from the centre of Comet 67P/Churyumov-Gerasimenko on 3 February and released on 9 February 2015. The image resolution is 2.4 m/pixel and the individual 1024 x 1024 frames measure 2.5 km across. The mosaic measures 4.2 […]

Sharpest Views of Mysterious 'Planet' Ceres Now Better Than Hubble, Tantalize Scientists

Comparison of Ceres images taken from NASA’s Dawn spacecraft on Jan. 25, 2015, and the Hubble Space Telescope up to January 2004. What is the nature of the ‘White Spot’ visible in both images? What new features are being revealed by Dawn? Dawn Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA. HST Credit: NASA, ESA, J. Parker (Southwest Research Institute), […]

After a seven-year trek, and at the dawn of a new year, NASA’s revolutionary Dawn spacecraft has begun the final approach phase to dwarf planet Ceres for an unprecedented examination of […]

Rosetta Team Focusing on Upcoming Comet and Lander Science, Planning Ultra Close Flyby

From the location where it came to rest after bounces, the Philae lander of the European Space Agency’s Rosetta mission captured this view of a cliff on the nucleus of comet 67P/Churyumov-Gerasimenko. The feature is called “Perihelion Cliff.” The image is from the lander’s CIVA camera. Credit: ESA/Rosetta/Philae/CIVA

The team guiding Europe’s history-making Rosetta […]
