The Space Show, hosted by David Livingston at www.TheSpaceShow.com, will have the following guests this week:
1. Monday, November 16, 2015, 2-3:30 PM PST (22-23:30 GMT)
Wayne Eleazer comes to discuss his recent Space Review articles.
Wayne Eleazer spent 25 years in the US Air Force, serving as the Thor program manager, GPS integration manager, Atlas test director at Vandenberg Air Force Base, and for a time led the space launch section of the Acquisition Directorate of the Air Force S [...]
What's happening to that meteor? A few days ago, a bright fireball was photographed from the Alps mountain range in Switzerland as it blazed across the sky. The fireball, likely from the Taurids meteor shower, was notable not only for how bright it was, but for the rare orange light it created that lingered for several minutes. Initially, the orange glow made it seem like the meteor trail was on fire. However, the orange glow, known as a persistent train, originated neither from fire nor sunligh [...]
There was a shower over Monument Valley -- but not water. Meteors. The featured image -- actually a composite of six exposures of about 30 seconds each -- was taken in 2001, a year when there was a very active Leonids shower. At that time, Earth was moving through a particularly dense swarm of sand-sized debris from Comet Tempel-Tuttle, so that meteor rates approached one visible streak per second. The meteors appear parallel because they all fall to Earth from the meteor shower radiant -- a poi [...]
Long shadows are cast by a low Sun across this rugged looking terrain. Captured by New Horizons, the scene is found just south of the southern tip Sputnik Planum, the informally named smooth, bright heart region of Pluto. Centered is a feature provisionally known as Wright Mons, a broad, tall mountain, about 150 kilometers across and 4 kilometers high, with a 56 kilometer wide, deep summit depression.
Of course, broad mountains with central craters are found elsewhere in the Solar System, li [...]
Astronomers using data from NASA's Fermi Gamma-ray Space Telescope have detected hints of periodic changes in the brightness of a so-called "active" galaxy, whose emissions are powered by a supersized black hole. If confirmed, the discovery would mark the first years-long cyclic gamma-ray emission ever detected from any galaxy, which could provide new insights into physical processes near the black hole.
"Looking at many years of data from Fermi's Large Area Telescope (LAT), we picked up indi [...]
The Expedition 45 crew is wrapping up the work week on biomedical science and Cygnus mission preparations. The orbital residents also worked maintenance throughout the numerous modules inside the International Space Station.
Flight Engineers Kjell Lindgren and Kimiya Yui, who both have been in space over 100 days, checked their vision and blood pressure for the long-running Ocular Health study. Yui then worked on experiment hardware inside Japan’s Kibo lab module. Lindgren explored growin [...]
