Dawn mission managers await NASA decision on spacecraft’s future
Artist’s concept of the Dawn spacecraft with one of its ion engines firing. Credit: NASA/JPL-Caltech The future of NASA’s Dawn spacecraft, running low on hydrazine fuel and now flying around the dwarf planet Ceres without the help of internal pointing wheels, will be decided in the coming weeks by top space agency managers. Scientists have…

Hunt for water at Ceres goes underground
The small, bright crater Oxo (6 miles, 10 kilometers wide) on Ceres is seen in this perspective view. The elevation has been exaggerated by a factor of two. The view was made using enhanced-color images from NASA’s Dawn mission. Dawn’s visible and infrared mapping spectrometer (VIR) has found evidence of water ice at this crater.…

Water, water everywhere on Ceres: Ice lies just below dwarf planet’s surface
NASA’s Dawn spacecraft determined the hydrogen content of the upper yard, or meter, of Ceres’ surface. Blue indicates where hydrogen content is higher, near the poles, while red indicates lower content at lower latitudes. (NASA / JPL-Caltech / UCLA / MPS / DLR / IDA / PSI Photo) Readings from instruments aboard NASA’s Dawn orbiter…

Pluto probe’s extended mission approved, but new Dawn destination denied
Artist’s concept of the New Horizons spacecraft’s encounter with a Kuiper Belt object. Credit: NASA/JHUAPL/SWRI/Alex Parker NASA managers formally approved the New Horizons mission another speedy encounter with an object at the frontier of the solar system, but denied a request from scientists to redirect the Dawn spacecraft to visit a third destination in the…

NASA extends New Horizons mission to Kuiper Belt, tells Dawn to stay at Ceres
Artwork shows the New Horizons probe flying by a Kuiper Belt object known as 2014 MU69. (Credit: NASA) Almost a year after New Horizons’ unprecedented flyby of Pluto, NASA has given the official go-ahead for the probe to fly past another icy object in the Kuiper Belt in 2019. At the same time, the space agency…

NASA must decide soon on Dawn mission’s next act
Artist’s concept of the Dawn spacecraft, with its ion propulsion system active, in orbit around the dwarf planet Ceres. Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA NASA managers face a July 12 deadline to decide whether to send the Dawn spacecraft on an unplanned visit to a third object in the asteroid belt or keep the probe at dwarf planet…

Dwarf planet Ceres’ mysterious bright spot hints at upwelling of salty water
The center of Ceres’ mysterious Occator Crater is the brightest area on the dwarf planet. The inset perspective view shows new data on this feature: Red signifies a high abundance of carbonates, while gray indicates a low carbonate abundance.

Dawn mission expected to go into overtime at Ceres
The bright central spots near the center of Occator Crater are shown in enhanced color in this view from NASA’s Dawn spacecraft. Such views can be used to highlight subtle color differences on Ceres’ surface. This image combines high-resolution black-and-white imagery from February 2016 with lower-resolution color data collected by Dawn in September 2015. NASA/JPL-Caltech/UCLA/MPS/DLR/IDA/PSI/LPI…
