A big hole in the ground has helped scientists piece together the structure of the dwarf planet Ceres. It's the largest member of the asteroid belt — about a quarter the size of the Moon. The hole shows that Ceres has layers, like a bigger planet or moon. A spacecraft studied Ceres from orbit for three years. Its most impressive discovery was Occator Crater. It's almost 60 miles wide and two miles deep. Big white blotches decorate its floor — deposits of salt. Occator probably formed about 20 million years ago, when a space rock hit Ceres. Recent work suggests there was a layer of salty, muddy water about 30 miles below the site. The impact fractured the crust, allowing some of the brine to leak into the crater floor. The water evaporated, leaving the salt. The crater also is marked by dozens of small rounded hills. They resemble features on Earth known as pingoes. They formed when water surged from below, pushing up the top layer of rocks and ice. Occator Crater and other features reveal that Ceres has several layers. Two of those layers — the crust and mantle — are separated by a layer of muddy brine — which can sometimes leak onto the surface. Ceres shines at its best for the year right now. It rises at sunset, is in view all night, and is brightest for the year. Through binoculars, it looks like a small, faint star to the lower left of the bright star Aldebaran as they climb into good view in the east by 9:30 or 10.  Script by Damond Benningfield Support McDonald Observatory

Using a neutron spectrometer onboard the Dawn spacecraft, scientists have found elevated concentrations of hydrogen in Ceres' Occator Crater, which provides evidence of an icy crust. Plus, everything is on fire in the western United States, and we review “The Past is Red” by Catherynne M.

So what is that white stuff that NASA's Dawn spacecraft found in Occator Crater on Ceres? What about that four mile high mountain or “pyramid”? We sort the wheat from the chaff. The International Space Station (ISS) Expedition 44 crew partook of the first edible harvest from the NASA's VEGGIE experiment becoming the first humans to harvest food grown in space while on orbit. We highlight efforts to use Asteroids as fueling depots for future deep space missions, and mention the successful spacewalk conducted by cosmonauts Gennady Padalka and Mikhail Kornienko on the station's Russian segment. We look at an unusual experiment flying on board  Japan's HTV 5 cargo vehicle to be launched to the ISS on Sunday August 16th. CBS News had a worthy feature on light pollution and its impact on ground based astronomy, we visit the piece for comment. NASA Administrator Charles Bolden sent a letter to Congress saying due to Congressional action, NASA was forced to extend the launch services contract with Russia into 2019 to the tune of $490 Million. Eric Berger of the Houston Chronicle had some thoughts on that topic similar to our own and we debate.  We visit the NTSB's findings of the October 31 Virgin Galactic accident  released on July 28th..
