This image is one of several NASA’s Dawn spacecraft took on approach to Ceres on 4th February 2015 at a distance of about 90,000 miles (145,000 kilometres) from the dwarf planet. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDANASA’s Dawn spacecraft, on approach to dwarf planet Ceres, has acquired its latest and closest-yet snapshots of this mysterious world. The images of Ceres were taken on 4th February 2015 from a distance of about 90,000 miles (145,000 kilometres).
At a resolution of 8.5 miles (14 kilometres) per pixel, the pictures represent the sharpest images to date of Ceres.This animation showcases a series of images obtained with the Framing Camera of NASA’s Dawn spacecraft on approach to Ceres on 4th February 2015 at a distance of about 90,000 miles (145,000 kilometres) from the dwarf planet. The resolution is 8.5 miles (14 kilometers) per pixel. Image credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDAAfter the spacecraft arrives and enters into orbit around the dwarf planet, it will study the intriguing world in great detail. Ceres, with a diameter of 590 miles (950 kilometres), is the largest object in the main asteroid belt, located between Mars and Jupiter.
In this image from NASA’s Cassini spacecraft we see a crater duo on Saturn’s 698-mile-wide moon Dione. The upper of the pair, named Italus, is overprinted on a grouping of ancient troughs called Petelia Fossae. The lower crater, Caieta, sits atop a feature named Helorus Fossa. Fossae on Dione are believed to be tectonic features.
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.
Astronomers searching the outer solar system for signs of a super Earth-size world beyond Pluto have found another small body in an orbit consistent with the presumed gravitational influence of the presumed Planet X.
