JPL’s venerable Ed Stone, the Project Scientist for the Voyager spacecraft for over 40 years, made an appearance on the Colbert Report last night, bantering easily with the no-holds-barred host and discussing the significance of the Voyager mission, from the two launches in 1977 to Voyager 1’s recent celebrated arrival in interstellar space.
Colbert also was tasked by NASA to present Stone with NASA’s Distinguished Public Service Medal for a lifetime of scientific achievement. See below:

The radiation-heavy Van Allen Belts around Earth contain particles that can move at almost the speed of light across vast distances, new research reveals. The information came from an instrument flown aboard the Van Allen Probes twin NASA spacecraft, which launched in 2012.
According to scientists, the process that creates this is similar to what happens in the Large Hadron Collider and other particle accelerators. The magnetic field on the Earth accelerates electrons faster as these particles orbit the planet. While scientists had spotted this process happening at small scales before, the new paper has seen this across hundreds of thousands of kilometers or miles.
“With the Van Allen Probes, I like to think there’s no place for these particles to hide because each spacecraft is spinning and ‘glimpses’ the entire sky with its detector ‘eyes’, so we’re essentially getting a 360-degree view in terms of direction, position, energy, and time,” stated Harlan Spence, principal scientist for the Energetic Particle, Composition, and Thermal Plasma (ECT) instrument aboard the probes, and co-author on the research paper. He is also director of the University of New Hampshire Institute for the Study of Earth, Oceans, and Space.
The research was led by University of Alberta physicist Ian Mann, and is available in Nature Communications. “People have considered that this acceleration process might be present but we haven’t been able to see it clearly until the Van Allen Probes,” Mann stated.

The next few years will be banner ones for learning about dwarf planets. While the high-profile New Horizons spacecraft zooms towards a Pluto date in 2015, the Dawn spacecraft is making a more stealthy (in terms of media coverage) run at Ceres, which is the smallest and closest dwarf planet to Earth.
The Dawn spacecraft, as readers likely recall, made its first port of call at fellow protoplanet Vesta. What excites scientists this time around is the likelihood of water ice on Ceres’ surface. Vesta, by contrast, was very dry.
Here’s Dawn’s agenda once it gets to Ceres in April 2015:
“Dawn will make its first full characterization of Ceres later in April, at an altitude of about 8,400 miles (13,500 kilometers) above the icy surface. Then, it will spiral down to an altitude of about 2,750 miles (4,430 kilometers), and obtain more science data in its survey science orbit. This phase will last for 22 days, and is designed to obtain a global view of Ceres with Dawn’s framing camera, and global maps with the visible and infrared mapping spectrometer (VIR),” NASA stated.
“Dawn will then continue to spiral its way down to an altitude of about 920 miles (1,480 kilometers), and in August 2015 will begin a two-month phase known as the high-altitude mapping orbit. During this phase, the spacecraft will continue to acquire near-global maps with the VIR and framing camera at higher resolution than in the survey phase. The spacecraft will also image in ‘stereo’ to resolve the surface in 3-D.”
Dawn will then zoom down to an altitude of just 233 miles (375 kilometers) in November 2015 for three months to obtain information about elements and the dwarf planet’s gravity. Dawn will use its Gamma Ray and Neutron Detector (GRaND) to do the first part and a gravity experiment to perform the second.

To conserve fuel, Dawn will also use a “hybrid” pointing control method to keep it on track, using both reaction wheels and thrusters to stay in the right direction. This is needed because two of its four reaction wheels had “developed excessive friction” by the time Dawn departed Vesta. The hybrid method was tested for 27 hours and successfully concluded Nov. 13. You can check out more about the hybrid mode at this link.
SpaceX is suing the Air Force for the right to compete for US national security satellites launches using Falcon 9 rockets such as this one which successfully launched the SES-8 communications satellite on Dec. 3, 2013 from Pad 40 at Cape Canaveral, FL. Credit: Ken Kremer/kenkremer.com
CAPE CANAVERAL AIR FORCE STATION, FL – SpaceX scored a spectacular launch success this evening (Dec. 3 ) when the maiden flight of their upgraded Falcon 9 rocket from Florida scorched the sky of the Florida Space Coast and successfully delivered a commercial space satellite to geostationary orbit for the first time ever – thereby revolutionizing the commercial space industry from this day forward.
The third time was finally the charm as the Falcon 9 blasted off precisely on time at 5:41 p.m. EST from Launch Complex 40 at Cape Canaveral following a pair of launch scrubs last week on Nov. 25 and Thanksgiving Day Nov. 28 caused by technical problems with the first stage engine.
The booster thundered off the pad and pierced the completely cloud free evening sky soon after sunset as the blistering roar rumbled deafeningly all across the space coast viewing area.
The rocket exhaust plume was easily visible for several minutes after liftoff of the historic mission.

The 3,138 kg (6,918 lbs) SES-8 satellite was built by Orbital Sciences for SES and is a hybrid Ku- and Ka-band spacecraft that will provide TV and communications coverage for the South Asia and Asia Pacific regions.
This new version of the Falcon 9 rocket has nearly 50% more thrust compared to the original Falcon 9.
The stakes could not have been higher for the future of SpaceX.
The firms future launch manifest of more than 50 flights for NASA and a variety of commercial entities worth billions of dollars were riding on the success of tonight’s liftoff from Cape Canaveral Air Force Station, Florida.
With 54 satellites in orbit SES is one of the largest commercial telecommunications satellite operators in the world.
The next generation Falcon 9 rocket injected the SES-8 telecommunications to its targeted geostationary transfer orbit flying 295 x 80,000 km above Earth.
A restart of the second stage engine was absolutely essential to the success of the mission since a failure to ignite would have doomed the SES-8 satellite from reaching is desired orbit since it’s a requirement for all geostationary transfer missions.
The picture-perfect flight met 100% of the mission objectives, SpaceX said in a post-launch statement.
“The successful insertion of the SES-8 satellite confirms the upgraded Falcon 9 launch vehicle delivers to the industry’s highest performance standards,” said Elon Musk, CEO and Chief Designer of SpaceX.
“As always, SpaceX remains committed to delivering the safest, most reliable launch vehicles on the market today. We appreciate SES’s early confidence in SpaceX and look forward to launching additional SES satellites in the years to come.”
Today’s launch marked SpaceX’s first commercial launch from Florida as well as the first commercial flight from Cape Canaveral Air Force Station in over five years.
Satellite operators have booked their commercial launches with other rocket companies overseas due to the high cost of other American expendable rockets.
SpaceX’s entire corporate aim has been to significantly cut the high cost of access to space.

With today’s SpaceX is sure to sign even more contracts bringing additional commercial telecommunications satellite space launches back to American soil.
Approximately 185 seconds into flight, the Falcon 9’s second stage equipped with a single Merlin 1-D engine ignited.
It burned for five minutes and 20 seconds to inject SES-8 satellite into its initial parking orbit.
Eighteen minutes later the second stage engine relit for a second time and fired for just over one minute to deliver SES-8 satellite to its final geostationary transfer orbit.

This extra powerful new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. The nine Merlin 1D engines 1.3 million pounds of thrust at sea level rises to 1.5 million pounds as the rocket climbs to orbit.
The Merlin 1 D engines are arrayed in an octaweb layout for improved efficiency.
Therefore the upgraded Falcon 9 can boost a much heavier cargo load to the ISS, low Earth orbit, geostationary orbit and beyond.
The next generation Falcon 9 is a monster. It measures 224 feet tall and is 12 feet in diameter. That compares to a 130 foot tall rocket for the original Falcon 9.

To determine what’s in the atmosphere of an exoplanet, astronomers watch the planet pass in front of its host star and look at which wavelengths of light are transmitted and which are partially absorbed. Credit:
NASA's Goddard Space Flight Center
For the first time, astronomers have found conclusive evidence of water in the hazy atmospheres of planets orbiting other stars. Using the Hubble Space Telescope, two teams of scientists found faint but clear signatures of water in the atmospheres of five exoplanets. All five are so-called ‘hot Jupiters,’ massive worlds that orbit close to their host stars.
“To actually detect the atmosphere of an exoplanet is extraordinarily difficult. But we were able to pull out a very clear signal, and it is water,” said Drake Deming from the University of Maryland, who led a study characterizing the atmospheres of two of the five planets.
“We’re very confident that we see a water signature for multiple planets,” said Avi Mandell, a planetary scientist at NASA’s Goddard Space Flight Center, and lead author of another paper on the remaining three exoplanets. “This work really opens the door for comparing how much water is present in atmospheres on different kinds of exoplanets, for example hotter versus cooler ones.”
The five planets are all well-studied, and would not be friendly places for life as we know it — with blazing temperatures and unusual conditions. WASP-17b is an unusual planet in a retrograde orbit, and sodium had already been detected in its atmosphere.
The atmosphere of WASP-12b already has been found to hold vast amounts of carbon as well as water. WASP-19b orbits a nearby star, and has one of the shortest orbital periods of any known planetary body, about 0.7888399 days or approximately 18.932 hours. XO-1b has the distinction of being discovered by amateur astronomers
The astronomers involved in the new studies say the strengths of the water signatures in each world varied, with WASP-17b and HD209458b having the strongest signals.
Currently, studying exoplanet atmospheres can be done when the planets are passing in front of their stars. Researchers can identify the gases in a planet’s atmosphere by determining which wavelengths of the star’s light are transmitted and which are partially absorbed. Deming’s team employed a new technique with longer exposure times, which increased the sensitivity of their measurements.
In both studies, scientists used Hubble’s Wide Field Camera 3 to explore the details of absorption of light through the planets’ atmospheres. The observations were made in a range of infrared wavelengths where a pattern that signifies the presence of water would appear if water were present. The teams compared the shapes and intensities of the absorption profiles, and the consistency of the signatures gave them confidence they saw water.
“These studies, combined with other Hubble observations, are showing us that there are a surprisingly large number of systems for which the signal of water is either attenuated or completely absent,” said Heather Knutson of the California Institute of Technology, a co-author on Deming’s paper. “This suggests that cloudy or hazy atmospheres may in fact be rather common for hot Jupiters.”
It’s actually remarkably beautiful, and well worth two minutes of your time.*
Assembled from actual photographs taken by astronauts aboard the Space Station, many of them by Don Pettit during Expedition 31 (Don took a lot of photos) this timelapse “The World Outside My Window” by David Peterson ramps up the artistic value by featuring super-duper high definition, smoothed frame transitions and a musical score by “Two Steps From Hell.” (Don’t worry, that sounds scarier than it is.) Even if you’ve seen some of these clips before, they’re worth another go.
After all, there’s no good reason not to be reminded of how beautiful our planet is from space. Enjoy!
*It’s actually two minutes and twenty-eight seconds but I don’t think you’ll mind.
We have another book review and giveaway for you! Just in time for the holidays.
Book review by David Dehetre of Universe Today.
Astronomy Photographer of the Year Collection 2 is a large format, glossy book that covers the Royal Observatory at Greenwich’s annual Astrophotography competition. It covers Earth and Space, Our Solar System, Deep Space, Young Astronomy Photographer, People and Space, Best Newcomer, and Robotic Scope from 2009 to 2012. It also includes a brief how-to primer on astrophotography which, while fine, seemed perfunctory and tacked on.
The book is organized by years and category, with nice double page section breaks with clear, detailed info alongside each image; however, within each year, the categories aren’t delineated, either through typographic means, such as headers or section breaks, or through any indication alongside the images themselves. Usually the category was obvious enough, but it was somewhat confusing at times. Each category contains images by the winner, runner-up, and sometimes one or more ‘highly-commended’ entrants. Some categories also had other images without any designation of why they were included. This could be a typographic omission of some sort, or it could be that they were just additional entrants worthy of inclusion.
I was happy to see the consistently high caliber of work that came out of the competition. There isn’t one image in the book that was less than outstanding. I’ve spent many a night far out in the countryside doing astrophotography as a hobby, and I’ve never come up with an image to compare.
I was also happy to see the competition segmented into subject areas as well as the more expected age/experience categories. This seems to acknowledge that there are different metrics and merit for the broad scope of styles/subjects in astrophotography.
One other point worth mentioning is I found many of the astrophotographers presented were people I was already familiar with, some from Flickr, some from You Tube, and some from periodicals like Sky at Night. I knew these people, and not because they produced and continue to produce great images, but because they are some of the people I learned astrophotography from thus illustrating one of the great underlying aspects of astrophotography: that it is collaborative in nature. I find it heartening that the people who share the most, who help others and communicate, seem to be the ones who do the best work and are the most successful.
I’m of two minds about Astronomy Photographer of the Year though. On the one hand, it’s very well done, beautiful, and stunning: really everything a person could ask for in a book on this subject. At the same time, however, it is trying to document something that is bigger and richer than can be captured in a book.
While the images are flawlessly presented, they lack the backlit brilliance provided by a computer screen, and they aren’t zoomable to view fine details. Many astrophotography images are available on-line at resolutions equivalent to wall-size if they were printed out.
There is also the problem of completeness. While the book is cover-to-cover with great images, in large part it is singular images from outstanding photographers who have dozens or hundreds of stunning images on-line. I found myself flipping a few pages at a time, and then being overcome with a desire to go search out a photographer’s other images. This is perhaps an inevitable outcome of the fact that the competition was conducted on-line (via Flickr), so it’s hard to see it as a negative.
All in all, it really is a fantastic book and I love having it on my shelf that I often randomly flip through to find myself getting inspired, but I don’t think I would have searched it out for that purpose, and I’m not sure who the target customer is supposed to be. It seems incomplete and cursory, especially in the technical details, for someone already involved with the hobby and yet it has a price tag and scope that seems inconsistent with an introductory level book. It would make a great addition to a library collection.

Venus (arrowed) imaged near the waning crescent Moon on August 13th, 2012. (Photo by author).
Here’s a feat of visual athletics to amaze your friends with this week. During your daily routine, you may have noticed the daytime Moon hanging against the azure blue sky. But did you know that, with careful practice and a little planning, you can see Venus in the broad daylight as well?
This week offers a great chance to try, using the daytime Moon as a guide. We recently wrote about the unique circumstances of this season’s evening apparition of the planet Venus. On Friday, December 6th, Venus will reach a maximum brilliancy of magnitude -4.7, over 16 times brighter than Sirius, the brightest star in the sky. And just one evening prior on Thursday December 5th, the 3-day old crescent Moon passes eight degrees above it, slightly closer together than the span of your palm held at arm’s length.
The orientation of Venus and the Moon on Thursday, December 5th as it crosses the local meridian at 3PM EST. Created using Starry Night Education software.
The Moon will thus make an excellent guide to spot Venus in the broad daylight. It’s even possible to nab the pair with a camera, if you can gauge the sky conditions and tweak the manual settings of your DSLR just right.
The best time to attempt this feat on Thursday will be when the pair transits the local meridian due south of your location. Deep in the southern hemisphere, the Moon and Venus will appear to transit to the north. This occurs right around 3:00 PM local. The fingernail Moon will be easy to spot, then simply begin scanning the sky to the south of it with the naked eye or binoculars for the brilliant diamond of Venus. High contrast and blocking the Sun out of view is key — Venus will easily pop right out against a clear deep blue sky, but it may disappear all together against a washed out white background.
The Moon will be at a 10% illuminated phase on Thursday, while Venus presents a slimming crescent at 27% illumination. Though tougher to find, Venus is actually brighter than the Moon in terms of albedo… expand it up to the apparent size of a Full Moon and it would be over four times as bright!

You’ll be amazed what an easy catch Venus is in the daytime once you’ve spotted it — we’ve included views of Venus in the daytime when visible during sidewalk star parties for years.
Due to its brilliancy, Venus has also been implicated in more UFO sightings than any other planet, and even caused the Indian Army to mistake the pair for snooping Chinese drones earlier this year when it was in conjunction with the planet Jupiter. A daytime sighting of the planet Venus near the Moon was almost certainly the “curious star” reported by startled villagers observing from Saint-Denis, France on January 13th, 1589.
Venus can also cast a noticeable shadow near greatest brilliancy, an effect that can be discerned against a fresh snow-covered landscape. Can’t see it? Take a time exposure shot of the ground and you may just be able to tease it out… but hurry, as the waxing Moon will soon be dominating the early evening night sky show!
Another phenomenon to watch for this week on the face of the waxing crescent Moon is known as Earthshine. Can you just make out the dark limb of the Moon? This is caused by the Earth acting as a “mirror” reflecting sunlight back at the nighttime side of the Moon. And don’t forget, China’s Chang’e-3 lander plus rover will be landing on the lunar surface in the Sinus Iridum region later this month on December 14th, the first lunar soft landing since 1976!
The imaginary line of the ecliptic currently bisects the Moon and Venus, as Venus sits at an extreme southern point 2.5 degrees below the ecliptic — in fact, 2013 the farthest south it’s been since 1930 — and the Moon sits over four degrees above the ecliptic this week. The Moon also reached another notable point today, as it reached its most northern “southerly point” for 2013 at a declination of -19.6 degrees. The Moon’s apparent path is headed for a “shallow year” in 2015, after which it’ll begin to slowly widen over its 18.6 year cycle out to a maximum declination range in 2024. It’s a weird but true fact that the motion of the Moon is not fixed to the Earth’s equatorial plane, but to the path of our orbit traced out by the ecliptic, to which its orbit is tilted an average of five degrees.
The view looking west tonight from latitude 30 degrees north. Created using Stellarium.
And speaking of the Moon, there’s another fun naked-eye feat you can attempt tonight. At dusk, U.S. East Coast observers might just be able to pick up the razor thin crescent Moon hanging low to the West, only 23 hours past New. Begin scanning the western horizon about 10 minutes after sunset. Can you see it with binoculars? The naked eye? Chances get better for sighting the slim crescent Moon the farther west you go. North American observers will have a chance at a “personal best” during next lunation in the first few days of 2014… more to come!

Decades after the last man walked on the moon, Apollo astronauts still get a lot of respect. Some of them have been portrayed in Hollywood movies. Many of them willingly, even in their advanced ages, give public lectures and sign autographs. And already, some observers are wondering about the loss to humanity when the last moonwalker dies.
But there is a still a percentage of the population that believes that the astronauts didn’t land on the moon at all. To address this, a couple of experienced hands in filmmaking started a new video series examining and debunking the common conspiracies.
Helming the project is Chris Riley, who produced and directed ‘First Orbit’ as well as two BBC biographies of Neil Armstrong and Richard Feynman, and animator Antony Buonomo, who won an Emmy for his work.
“This Christmas it will be 45 years since the first astronauts reached lunar orbit, and yet conspiracy theories continue to question if the Moonshots ever really happened,” a press release stated.
“The first episode of their Apollo Fact Files has recently been released and Riley is now launching a Kickstarter campaign to raise £5000, which he will use to fund eleven more episodes.”
“Of course, I am trying to debunk the conspiracy theorists, but unlike them, I want people to look at their evidence rationally and critically, and not swallow it whole. It’ll choke you if you do,” Plait wrote at the time.

CAPE CANAVERAL, FL – Today (Dec. 3) marks the 3rd attempt by SpaceX to launch the maiden flight of their significantly upgraded Falcon 9 rocket with the SES-8 telecommunications satellite – following the Nov. 28 ‘Thanksgiving = Spacegiving Day’ scrub due to an aborted 1st stage engine firing in progress.
And the stakes could not be higher for the future of SpaceX – with the firms future launch manifest worth billions of dollars riding on the success of today’s liftoff from Cape Canaveral Air Force Station, Florida.
In an unprecedented launch event for SpaceX, the upper stage engine on the next generation Falcon 9 booster absolutely must restart in flight for a second time in order for the commercial SES-8 payload to be delivered to geostationary transfer orbit (GTO).
Blastoff from Cape Canaveral’s seaside Space Launch Complex 40 is set for 5:41 p.m. EST (2241 GMT).
The Thanksgiving Day launch was aborted by the computers when the Marlin engines thrust failed to build up as fast as planned.
The weather forecast currently shows a 90% chance of favorable conditions at liftoff time according to Air Force meteorologists. The only concern is for winds.

The launch of SES-8 is a milestone marking the first ever attempt by SpaceX to place a satellite into the geostationary orbit replete with numerous high value commercial satellites. This is the doorway to the future profitability of SpaceX.
“I don’t want to tempt fate, but I think it’s going to have a pretty significant impact on the world launch market and on the launch industry because our prices are the most competitive of any in the world,” said SpaceX CEO and chief designer Elon Musk at a prelaunch briefing for media including Universe Today in Cocoa Beach, FL.
For the mission to be declared a success, the upper stage engine must reignite precisely as planned about 27 minutes after liftoff and burn for approximately 1 minute to successfully propel SES-8 into the propel orbit about 33 minutes after launch.

“Whether or not this launch is successful, I’m confident we will certainly make it on some subsequent launch,” said Musk.
“This is really rocking the industry. Everybody has to look out,” said Martin Halliwell, SES chief technical officer, who joined Musk at the prelaunch meeting.
The upgraded Falcon 9 will also be the launcher utilized for the manned SpaceX Dragon capsules launching to the ISS sometime later this decade!
And the very next satellite set for launch by SpaceX later in December – Thaicom 6- is essentially already waiting at the door to the onramp to space.
SpaceX plans a live broadcast of the Falcon 9 liftoff from pad 40 on Cape Canaveral Air Force Station, FL beginning at 5 p.m. EST.
It can be viewed here: www.spacex.com/webcast
The show will feature commentary about the Falcon 9 rocket and launch sequences and the SES-8 commercial satellite from SpaceX corporate headquarters in Hawthorne, CA.
The Falcon 9/SES-8 launch window extends for 86 minutes until 7:07 p.m. EST.
The 3,138 kg (6,918 lbs) SES-8 satellite is a hybrid Ku- and Ka-band spacecraft that will provide TV and communications coverage for the South Asia and Asia Pacific regions.
This mighty new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. The nine Merlin 1D engines 1.3 million pounds of thrust at sea level that rises to 1.5 million pounds as the rocket climbs to orbit
The Merlin 1-D engines are arrayed in an octaweb layout for improved efficiency.
Therefore the upgraded Falcon 9 can boost a much heavier cargo load to the ISS, low Earth orbit, geostationary orbit and beyond.
The next generation Falcon 9 is a monster. It measures 224 feet tall and is 12 feet in diameter. That compares to 13 stories for the original Falcon 9.
