As the powerful category 4 Hurricane Joaquin was pounding the Bahamas and packing winds of over 130 mph, NASA astronaut Scott Kelly captured a stunning photo of Joaquin on Friday morning, Oct. 2 from his perch aboard the International Space Station (ISS). As of today, Oct. 3. Joaquin has gained strength to 150 mph and is a borderline Cat 5 storm!
Coincidentally, Kelly snapped the photo within hours of the milestone 100th straight successful rocket launch by United Launch Alliance (ULA) on Oct. 2, of the firms Atlas V rocket carrying Mexico’s next generation Morelos-3 communications satellite from Florida to orbit. [click to continue…]

In ancient Greek lore, the Titans were giant deities of incredible strength who ruled during the legendary Golden Age and gave birth to the Olympian gods we all know and love. Saturn‘s largest moon, known as Titan, is therefore appropriately named. In addition to being Saturn’s largest moon – and the second-largest moon in the Solar System (after Jupiter’s moon Ganymede) – it is larger by volume than even the smallest planet, Mercury.
Beyond its size, Titan is also fascinating because it is the only natural satellite known to have a dense atmosphere, a fact which has made it very difficult to study until recently. On top of all that, it is the only object other than Earth where clear evidence of stable bodies of surface liquid has been found. All of this makes Titan the focal point of a great deal of curiosity, and a prime location for future scientific missions.

United Launch Alliance (ULA) celebrated an incredible milestone today, Oct. 2, with the successful launch of the firms 100th mission on an Atlas V rocket carrying Mexico’s next generation Morelos-3 satellite to provide advanced telecommunications for education and health programs for rural communities and secure communications for Mexican national security needs.
The spectacular predawn liftoff finally took place at 6:28 a.m. EDT from Space Launch Complex 41 on Cape Canaveral Air Force Station, Florida – after nearly being derailed by a [click to continue…]
The left image shows a mosaic of images taken by the Cassini spacecraft in near infrared light. Titan’s polar seas are visible as sunlight glints off of them. The reflection is in the southern part of Kraken Mare, Titan’s largest body of liquid. It consists of liquid methane and other hydrocarbons (compounds of hydrogen and carbon). The right image is a radar image of Kraken Mare, also obtained by Cassini. ‘Kraken’ is the name of a legendary Norse sea monster, and the name apparently alludes (at least fancifully) to the hopes of astrobiologists regarding this intriguing alien sea.

Could there be life on Saturn’s large moon Titan? Asking the question forces astrobiologists and chemists to think carefully and creatively about the chemistry of life, and how it might be different on other worlds than it is on Earth. In February, a team of researchers from Cornell University, including chemical engineering graduate student James Stevenson, planetary scientist Jonathan Lunine, and chemical engineer Paulette Clancy, published a pioneering study arguing that cell membranes could form under the exotic chemical conditions present on this remarkable moon.

Charon in Enhanced Color with Grand Canyon
NASA’s New Horizons captured this high-resolution enhanced color view of Charon and its Grand Canyon just before closest approach on July 14, 2015. The image combines blue, red and infrared images taken by the spacecraft’s Ralph/Multispectral Visual Imaging Camera (MVIC); the colors are processed to best highlight the variation of surface properties across Charon. Charon’s color palette is not as diverse as Pluto’s; most striking is the reddish north (top) polar region, informally named Mordor Macula. Charon is 754 miles (1,214 kilometers) across; this image resolves details as small as 1.8 miles (2.9 kilometers). Credits: NASA/JHUAPL/SwRI
Charon suffered such a surprisingly violent past of titanic upheavals that they created a humongous canyon stretching across the entire face of Pluto’s largest moon – as revealed in a fresh batch of images just returned from NASA’s New Horizons spacecraft.
We have been agog in amazement these past few weeks as New Horizons focused its attention on transmitting astounding high resolution imagery and data of Pluto, captured during mankind’s history making first encounter with our solar systems last unexplored planet on July 14, 2015, at a distance of 7,750 miles (12,500 kilometers).
Now after tantalizing hints we see that Charon, Pluto’s largest moon, did [click to continue…]

NEW JERSEY – A wide swath of the US East Coast is bracing for impact in the coming days as ‘Hurricane Joaquin’ strengthened to a major and dangerous Category 4 storm, today, Thursday, Oct. 1, as NASA and NOAA satellites keep constant watch as it barrels potentially towards tens of millions of coastal residents.
Joaquin is already packing winds exceeding 130 mph with even higher wind gusts as the storm continues to strengthen at this hour and the pressure is decreasing. See the latest Hurricane Joaquin animation and imagery from NASA and NOAA, above and below.
Meanwhile amidst the hurricane watch, launch preparations are underway by United Launch Alliance (ULA) for the firms 100th rocket blastoff on [click to continue…]
The new nova in Sagittarius is located just above the Spout in the Teapot only 1/2 degree from the popular star cluster-dark nebula deep sky pair NGC 6520 and Barnard 86. At about magnitude +9, the nova is visible in small telescopes. The two stars in the Teapot’s spout – Gamma and Delta Sgr – are labeled. This photo was taken September 28 just as clouds were rolling in. Credit: Bob King
A nova farmer would do well in the fields of Sagittarius. Four nights ago on September 27, Japanese amateur Koichi Itagaki plucked another “new star” from its starry furrows, the third nova discovered there this year!
For a few days, it was informally called Nova Sagittarii #3, but today received the official title of V5669 Sagittarii. Like the others, this one’s bright enough to see in a small telescope. [click to continue…]
This map-projected view of Ceres was created from images taken by NASA’s Dawn spacecraft during its high-altitude mapping orbit, in August and September, 2015. This color coded map can provide valuable insights into the mineral composition of the surface, as well as the relative ages of surface features. Credits: NASA/JPL-Caltech/UCLA/MPS/DLR/IDA
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. [click to continue…]

KENNEDY SPACE CENTER, FL – NASA’s Mobile Launcher (ML) is undergoing major upgrades and modifications at the Kennedy Space Center in Florida enabling the massive structure to launch the agency’s mammoth Space Launch System (SLS) rocket and Orion crew capsule on a grand ‘Journey to Mars.’
“We just finished up major structural steel modifications to the ML, including work to increase the size of the rocket exhaust hole,” Eric Ernst, NASA Mobile Launch project manager, told Universe Today during an exclusive interview and inspection tour up and down the Mobile Launcher.
Indeed the Mobile Launcher is the astronauts gateway to [click to continue…]
