[LINK] “Scientists Tantalized as Dawn Yields Global Mineral and Topographic Maps of Ceres”

leave a comment »

Universe Today’s Ken Kremer describes the progress made by Dawn in mapping dwarf planet Ceres. I am very fond of mapping celestial bodies, myself.

Slowly but surely the mysteries of dwarf planet Ceres are being peeled back layer by layer as NASA’s Dawn spacecraft orbits lower and lower and gathers detailed measurements that have now yielded global mineral and topographic maps, tantalizing researchers with the best resolution ever.

The Dawn science team has been painstakingly stitching together the spectral and imaging products captured from the lowest orbit yet achieved into high resolution global maps of Ceres, released today Sept. 30, by NASA.

“Ceres continues to amaze, yet puzzle us, as we examine our multitude of images, spectra and now energetic particle bursts,” said Chris Russell, Dawn principal investigator at the University of California, Los Angeles, in a statement.

The color coded map above is providing researchers with valuable insights into the mineral composition of Ceres surface, as well as the relative ages of the surface features that were a near total mystery until Dawn arrived on March 6, 2015.

The false-color mineral map view combines images taken using infrared (920 nanometers), red (750 nanometers) and blue (440 nanometers) spectral filters.

leave a comment »

Universe Today’s Ken Kremer reports on the success of India’s mission to Mars.

India’s historic first mission to Mars is now celebrating one year orbiting the Red Planet and may continue working for years to come. During year one the spacecraft was highly productive, achieving its goals of taking hordes of breathtaking images and gathering scientific measurements to study Mars atmosphere, surface environments, morphology, and mineralogy.

The Mars Orbiter Mission, or MOM, is India’s first deep space voyager to explore beyond the confines of her home planets influence and successfully arrived at the Red Planet after the “history creating” orbital insertion maneuver on Sept. 23/24, 2014 following a ten month interplanetary journey from Earth.

The MOM orbiter was designed and developed by the Indian Space Research Organization (ISRO), India’s space agency, which is the equivalent of NASA.

“Mars Orbiter spacecraft marks one year of its life around the Red Planet today [Sept. 24, IST],” said ISRO. It was primarily designed as a technology demonstrator but is also outfitted with significant science instruments.

leave a comment »

Universe Today’s Ken Kremer reports on China’s plans.

China aims to land a science probe and research rover on the far side of the Moon by 2020, say Chinese officials.

Chinese scientists plan to carry out the highly complex lunar landing mission using a near identical back up to the nations highly successful Chang’e-3 rover and lander – which touched down in December 2013.

If successful, China would become the first country to accomplish the history making task of a Lunar far side landing.

“The mission will be carried out by Chang’e-4, a backup probe for Chang’e-3, and is slated to be launched before 2020,” said Zou Yongliao from the moon exploration department under the Chinese Academy of Sciences, according to a recent report in China’s government owned Xinhua news agency.

Zou made the remarks at a deep-space exploration forum in China.

“China will be the first to complete the task if it is successful,” said Zou.
