International Space Station Achieves 15 Years of Continuous Human Presence in Orbit  The International Space Station (ISS) has grown tremendously in size and complexity and evolved significantly over 15 years of continuous human occupation from Nov. 2, 2000 to Nov. 2, 2015. Credit: NASA The International Space Station (ISS) achieved 15 years of a continuous human presence in orbit, as of today, Nov. 2, aboard the football field sized research laboratory ever since the first Russian/American crew of three cosmonauts and astronauts comprising Expedition 1 arrived in a Soyuz capsule at the then much tinier infant orbiting complex on Nov. 2, 2000. Today, the space station is host to the Expedition 45 crew of six humans – from America, Russia and Japan – that very symbolically also includes the first ever crew spending one year aboard and that highlights the outposts expanding role from a research lab to a deep space exploration test bed for experiments and technologies required for sending humans on interplanetary journeys to the Martian system in the 2030s. The ISS was only made possible by over two decades of peaceful and(...)

Astronomy Cast Ep. 391: Entropy
Have you ever been doing thermodynamics in a closed system and noticed that there's a finite number of ways that things can be arranged, and they tend towards disorder? Of course you have, we all have. That's entropy. And here in our Universe, entropy is on the rise. Let's learn about entropy in its specific, thermodynamic ways, and then figure out what this means for the future of the Universe.

The object moves from left to right across the center of the field. Credit: B. Bolin, R. Jedicke, M. Micheli Get ready for a man-made fireball. A object discovered by the Catalina Sky Survey on Oct 3rd temporarily designated WT1190F is predicted to impact the Earth about 60 miles (100 km) of the southern coast of Sri Lanka around 6:20 Universal Time (12:20 a.m CST) on November 13. The objects orbits Earth with a period of about three weeks. Because it was also observed twice in 2013 by the same survey team, astronomers have the data they need to model its orbit and trajectory, and as far anyone can tell, it’s likely man-made. (...)

One Year after Antares Failure, Orbital ATK Revamps Rocket for 2016 'Return to Flight'  Base of Orbital Sciences Antares rocket explodes moments after blastoff from NASA's Wallops Flight Facility, VA, on Oct. 28, 2014, at 6:22 p.m. Credit: Ken Kremer – kenkremer.com One year after the catastrophic launch failure of Orbital ATK's private Antares rocket seconds after liftoff with the Cygnus cargo freighter bound for the International Space Station (ISS), the firm is well on the way towards revamping the booster with modern new engines and implementing a 'Return or Flight' by approximately mid-2016, company officials told Universe Today. Antares is on the comeback trail. Some 15 seconds after blastoff of the firms Antares/Cygnus rocket on October 28, 2014 on the Orb-3 resupply mission for NASA to the space station, the flight rapidly devolved into total disaster when one of the rockets first stage AJ26 engines suddenly blew up without warning after liftoff from NASA Wallops Island facility along the Eastern shore of Virginia at 6:22 p.m. ET. After thoroughly investigating and evaluating the causes of the Orb-3 disaster, the top management of (...)

Charon's Twin 'Star Wars' Craters Are Distinctly Different; New Horizons Continues Toward KBO  This composite image is based on observations from the New Horizons Ralph/LEISA instrument made at 10:25 UT (6:25 a.m. EDT) on July 14, 2015, when New Horizons was 50,000 miles (81,000 kilometers) from Charon. Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute. Just like Luke and Leia, two craters named for the Star Wars twins (Skywalker and Organa) have many similarities. They look about the same size and shape, and appear to have been created at the same time, and therefore are about the same age. But instruments on the New Horizons spacecraft detected one major difference: Organa and its surrounding area are laced with ammonia. “Why are these two similar-looking and similar-sized craters, so near to each other, so compositionally distinct?” asked Will Grundy, who leads the New Horizons Composition team. “We have various ideas when it comes to the ammonia in Organa. The crater could be younger, or perhaps the impact that created it hit a pocket of ammonia-rich subsurface ice. Alternatively, maybe Organa's impactor delivered its own ammonia.”

Images from Enceladus 'Plume Dive' Courtesy of Cassini  Enceladus looms into the view of Cassini in this unprocessed Oct 28th image. Image credit: NASA/JPL Caltech/Space Science Institute Oh, to hitch a ride aboard NASA's Cassini spacecraft this week. The Saturn orbiting sentinel recently completed an amazing series of passes near the enigmatic ice-covered moon Enceladus, including a daredevil dive only 49 km (31 miles) above the southern pole of the moon and through an ice geyser. Images of the dramatic flyby were released by the Cassini team earlier this morning, revealing the moon in stunning detail. (...)

Dawn Starts Steep Descent to Most Dazzling Orbit of Ceres  This mosaic shows Ceres’ Occator crater and surrounding terrain from an altitude of 915 miles (1,470 kilometers), as seen by NASA’s Dawn spacecraft. Occator is about 60 miles (90 kilometers) across and 2 miles (4 kilometers) deep. Credits: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA The most dazzling views ever seen of dwarf planet Ceres and its mysterious bright spots are what's on tap by year's end as NASA’s amazing Dawn spacecraft starts a gradual but steep descent over the next two months to its lowest and final orbit around the bizarre icy body. Engineers at NASA’s Jet Propulsion Laboratory (JPL) successfully fired up the probes exotic ion propulsion system to begin lowering Dawn's orbital altitude to less than a quarter of what it has been for the past two months of intense mapping operations. On Oct. 23, Dawn began a seven-week-long dive that uses (...)
