NASA’s Dawn mission gears up for close look at Ceres

20 October 2017 Stephen Clark

NASA’s Dawn spacecraft will remain at Ceres for the rest of its mission, heading closer to the asteroid belt’s largest resident than ever before to obtain new measurements of ice, salts and a tenuous intermittent atmosphere detected around the dwarf planet, the space agency announced Thursday.

Scientists celebrate 10th anniversary of Dawn mission’s launch

In the ten years since its launch from Cape Canaveral, NASA’s Dawn spacecraft has orbited the two largest worlds in the asteroid belt and overcome defective components that threatened to derail the mission on its 4 billion-mile voyage, discovering unexpectedly rich geologic tapestries suggesting both destinations have a watery past.

Dawn mission managers await NASA decision on spacecraft’s future

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.

Movie shows Ceres at opposition from Sun

17 May 2017 Astronomy Now

NASA’s Dawn spacecraft successfully observed Ceres at opposition on April 29, taking images from a position exactly between the Sun and Ceres’ surface. Mission specialists had carefully maneuvered Dawn into a special orbit so that the spacecraft could view Occator Crater, which contains the brightest area of Ceres, from this new perspective.

Ceres’ temporary atmosphere linked to solar activity

7 April 2017 Astronomy Now

Scientists have long thought that Ceres may have a very weak, transient atmosphere, but mysteries lingered about its origin and why it’s not always present. Now, researchers suggest that this temporary atmosphere appears to be related to the behaviour of the Sun, rather than Ceres’ proximity to the Sun.

Hunt for water at Ceres goes underground

23 December 2016 Stephen Clark

NASA’s Dawn spacecraft has continued its survey of the dwarf planet Ceres this year, discovering rock-bound ice hidden just beneath the airless world’s rugged surface and a handful of icy outcrops inside craters in the northern hemisphere, raising hopes that Ceres could have once held a buried habitable ocean of liquid water.
