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), […]

Dawn Spacecraft Takes Its Best-Yet Image of Dwarf Planet Ceres

The best image of dwarf planet Ceres obtained so far by the Dawn spacecraft, from 740,000 miles (1.2 million kilometers) away. Images will get much better as the spacecraft approaches Ceres over the next few months. Image Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA

The Dawn spacecraft continues to make its way closer to a world which still hasn’t […]

Crowdfunding Campaign Aims to Launch Ambitious Lunar Science Mission

A recently launched crowdfunding campaign aims to finance the development of an ambitious and challenging lunar science mission, called “Lunar Mission One,” to the Moon’s south pole. The project’s backers hope that this will help kickstart a new era in lunar exploration, while creating a legacy for the way space missions are funded. Image […]
