Feathered Flight during Virgin Galactic's SpaceShipTwo's third powered flight on January 10, 2014 over the Mojave desert. This image was taken by MARS Scientific as part of the Mobile Aerospace Reconnaissance System optical tracking system.
2014 should be the year that Virgin Galactic’s SpaceShipTwo (SS2) brings passengers on suborbital space flights, and the company started off the year by successfully completing its third rocket-powered supersonic flight today. Virgin Galactic said they accomplished all of the objectives for this test flight.
“Today’s flight was another resounding success,” said Virgin Galactic CEO George Whitesides. “We focused on gathering more transonic and supersonic data, and our chief pilot, Dave, handled the vehicle beautifully. With each flight test, we are progressively closer to our target of starting commercial service in 2014.”
This was the third supersonic, rocket-powered test of the Virgin Galactic system after dozens of successful subsonic test flights.
Virgin Galactic’s Chief Pilot Dave Mackay piloted the craft along with Scaled Composites’ Test Pilot Mark Stucky. They tested the spaceship’s Reaction Control System, the newly installed thermal protection coating on the vehicle’s tail booms, and the “feather” re-entry system.
Virgin Galactic said the RCS will allow its pilots to maneuver the vehicle in space so that passengers will have great views of Earth, as well as aiding the positioning process for spacecraft re-entry. The new reflective protection coating on SS2’s inner tail boom surfaces is being evaluated to help maintain vehicle skin temperatures while the rocket motor is firing.
Today’s flight departed Mojave Air and Space Port at 7:22 a.m. PST. The WhiteKnightTwo (WK2) carrier aircraft brought SS2 to an altitude around 46,000 ft. Then SS2 was released, and its rocket motor was ignited, powering the spaceship to a planned altitude of 71,000 ft. That is SS2’s highest altitude to date, and it also reached a speed of Mach 1.4.
“I couldn’t be happier to start the New Year with all the pieces visibly in place for the start of full space flights,” said Virgin Galactic founder Sir Richard Branson. “2014 will be the year when we will finally put our beautiful spaceship in her natural environment of space. Today, we had our own Chief Pilot flying another flawless supersonic flight and proving the various systems required to take us safely to space, as well as providing the very best experience while we’re up there.”
An artist's concept of the latest, highly accurate measurement of the Universe from BOSS. The spheres show the current size of the "baryon acoustic oscillations" (BAOs) from the early universe, which have helped to set the distribution of galaxies that we see in the universe today. Galaxies have a slight tendency to align along the edges of the spheres — the alignment has been greatly exaggerated in this illustration. BAOs can be used as a "standard ruler" (white line) to measure the distances to all the galaxies in the universe. Credit: Zosia Rostomian, Lawrence Berkeley National Laboratory
When it comes to accuracy, everyone strives for a hundred percent, but measuring cosmic distances leaves a bit more to chance. Just days ago, researchers from the Baryon Oscillation Spectroscopic Survey (BOSS) announced to the world that they have been able to measure the distance to galaxies located more than six billion light-years away to a confidence level of just one percent. If this announcement doesn’t seem exciting, then think on what it means to other studies. These new measurements give a parameter to the properties of the ubiquitous “dark energy” – the source of universal expansion.
“There are not many things in our daily lives that we know to one-percent accuracy,” said David Schlegel, a physicist at Lawrence Berkeley National Laboratory (LBNL) and the principal investigator of BOSS. “I now know the size of the universe better than I know the size of my house.”
The research team’s findings were presented at the meeting of the American Astronomical Society by Harvard University astronomer Daniel Eisenstein, the director of the Sloan Digital Sky Survey III (SDSS-III), the worldwide organization which includes BOSS. They are detailed in a series of articles submitted to journals by the BOSS collaboration last month, all of which are now available as online preprints.
“Determining distance is a fundamental challenge of astronomy,” said Eisenstein. “You see something in the sky — how far away is it? Once you know how far away it is, learning everything else about it is suddenly much easier.”
When it comes to measuring distances in space, astronomers have employed many methods. To measure distances to planets has been accomplished using radar, but it has its constraints and going further into space means a less direct method. Even though they have been proved to be amazingly accurate, there is still an uncertainty factor involved – one that is expressed as a percentage. For example, if you were to measure the distance from an object 200 miles away to within a true value of 2 miles, then you have measured with an accuracy of 1%. Cosmically speaking, just a few hundred stars and a handful of star clusters are actually close enough to have their distances so accurately predicted. They reside within the Milky Way and are just a few thousand light-years away. BOSS takes it to the extreme… its measurements go well beyond our galactic boundaries, more than a million times further, and maps the Universe with unparalleled accuracy.
Thanks to these new, highly-accurate distance measurements, BOSS astronomers are making headway in the field of dark energy. “We don’t yet understand what dark energy is,” explained Eisenstein, “but we can measure its properties. Then, we compare those values to what we expect them to be, given our current understanding of the universe. The better our measurements, the more we can learn.”
Just how is it done? To achieve a one-percent measurement at six billion light years isn’t as easy as measuring a solar system object, or even one contained within our galaxy. That’s where the BOSS comes into play. It’s the largest of the four projects that make up the Sloan Digital Sky Survey III (SDSS-III), and was built to take advantage of this technique: measuring the so-called “baryon acoustic oscillations” (BAOs), subtle periodic ripples in the distribution of galaxies in the cosmos. These ripples are the signature of pressure waves which once cruised the early Universe at a time when things were so hot and dense that photons marched along with baryons – the stuff which creates the nuclei of atoms. Since the size of the ripple is known, that size can now be measured by mapping galaxies.
“With these galaxy measurements, nature has given us a beautiful ruler,” said Ashley Ross, an astronomer from the University of Portsmouth. “The ruler happens to be half a billion light-years long, so we can use it to measure distances precisely, even from very far away.
Using its specialized instrumentation which can make detailed measurements of a thousand galaxies at a time, BOSS took on a huge challenge – mapping the location of more than a million galaxies. “On a clear night when everything goes perfectly, we can add more than 8000 galaxies and quasars to the map,” said Kaike Pan, who leads the team of observers at the SDSS-III’s Sloan Foundation 2.5-meter Telescope at Apache Point Observatory in New Mexico.
Although the BOSS research team presented its early galaxy maps and beginning BAO measurements a year ago, this new data covers twice as much territory and gives an even more accurate measurement – including those to nearby galaxies. “Making these measurements at two different distances allows us to see how the expansion of the universe has changed over time, which will help us understand why it is accelerating,” explained University of Portsmouth astronomer Rita Tojeiro, who co-chairs the BOSS galaxy clustering working group along with Jeremy Tinker of New York University.
Also doing a similar study is Mariana Vargas-Magana, a postdoctoral researcher at Carnegie Mellon University. To enable even more accuracy, she’s looking into any subtle effects which could influence the BOSS measurements. “When you’re trying to reach one percent, you have to be paranoid about everything that could go even slightly wrong,” said Vargas-Magana — for example, slight differences in how galaxies were identified could have thrown off the entire measurement of their distribution, so different parts of the sky had to be checked carefully. “Fortunately,” Vargas-Magana said, “there are plenty of careful people on our team to check our assumptions. By the time all of them are satisfied, we are sure we didn’t miss anything.”
As of the present, these new BOSS findings would seem to be consistent with what we consider to be form of dark energy – a constant found throughout the history of the Universe. According to the news release, this “cosmological constant” is one of just six numbers required to create a model which coincides with the scale and structure of the Universe. Schlegel compares this six-number model to a pane of glass, which is pinned in place by bolts that represent different measurements of the history of the Universe. “BOSS now has one of the tightest of those bolts, and we just gave it another half-turn,” said Schlegel. “Each time you ratchet up the tension and the glass doesn’t break, that’s a success of the model.”
SBW2007 is a nebula with a giant star at its center. All indications are that it could explode as a supernova at any time. Credit: ESA/NASA, acknowledgement: Nick Rose.
No, this isn’t a distant view of the London Eye. This nebula with a giant star at its center is known as SBW2007, located in the Carina Nebula. Astronomers say it has striking similarities to a star that went supernova back in 1987, SN 1987A. Both stars had identical rings of the same size and age, which were travelling at similar speeds; both were located in similar HII regions; and they had the same brightness. We didn’t have the telescopic firepower back before 1987 like we do now, so we don’t have a closeup view of how SN 1987A looked before it exploded, but astonomers think SBW2007 is a snapshot of SN1987a’s appearance, pre-supernova.
Of course, no one can predict when a star will go supernova, and since SBW2007 is 20,000 light-years away, we don’t have any worries about it causing any problems here on Earth. But astronomers are certainly hoping they’ll have the chance to watch it happen.
SN 1987A is the closest supernova to that we’ve been able to study since the invention of the telescope and it has provided scientists with good opportunities to study the physical processes of an exploding star.
Below is the latest image of SN 1987A, courtesy of the National Radio Astronomy Observatory. You can read about their recent findings here, where they were able to image the newly formed dust from the explosion.

One star player in this week’s findings out of the 223rd meeting of the American Astronomical Society has been the Nuclear Spectroscopic Telescope Array Mission, also known as NuSTAR. On Thursday, researchers revealed some exciting new results and images from the mission, as well as what we can expect from NuSTAR down the road.
NuSTAR was launched on June 13th, 2012 on a Pegasus XL rocket deployed from a Lockheed L-1011 “TriStar” aircraft flying near the Kwajalein Atoll in the middle of the Pacific Ocean.
Part of a new series of low-cost missions, NuSTAR is the first of its kind to employ a space telescope focusing on the high energy X-ray end of the spectrum centered around 5-80 KeV.
Daniel Stern, part of the NuSTAR team at JPL Caltech, revealed a new X-ray image of the now-famous supernova remnant dubbed “The Hand of God.” Discovered by the Einstein X-ray observatory in 1982, the Hand is home to pulsar PSR B1509-58 or B1509 for short, and sits about 18,000 light years away in the southern hemisphere constellation Circinus. B1509 spins about 7 times per second, and the supernova that formed the pulsar is estimated to have occurred 20,000 years ago and would’ve been visible form Earth about 2,000 years ago.

While the Chandra X-ray observatory has scrutinized the region before, NuSTAR can peer into its very heart. In fact, Stern notes that views from NuSTAR take on less of an appearance of a “Hand” and more of a “Fist”. Of course, the appearance of any nebula is a matter of perspective. Pareidolia litter the deep sky, whether it’s the Pillars of Creation to the Owl Nebula. We can’t help but being reminded of the mysterious “cosmic hand” that the Guardians of Oa of Green Lantern fame saw when they peered back at the moment of creation. Apparently, the “Hand” is also rather Simpson-esque, sporting only three “fingers!”

NuSTAR is the first, and so far only, focusing hard X-ray observatory deployed in orbit. NuSTAR employs what’s known as grazing incidence optics in a Wolter telescope configuration, and the concentric shells of the detector look like layers on an onion. NuSTAR also requires a large focal length, and employs a long boom that was deployed shortly after launch.
The hard X-ray regime that NuSTAR monitors is similar to what you encounter in your dentist’s office or in a TSA body scanner. Unlike the JEM-X monitor aboard ESA’s INTERGRAL or the Swift observatory, which have a broad resolution of about half a degree to a degree, NuSTAR has an unprecedented resolution of about 18 arc seconds.
The first data release from NuSTAR was in late 2013. NuSTAR is just begging to show its stuff, however, in terms of what researchers anticipate that it’s capable of.
“NuSTAR is uniquely able to map the Titanium-44 emission, which is a radioactive tracer of (supernova) explosion physics,” Daniel Stern told Universe Today.
NuSTAR will also be able to pinpoint high energy sources at the center of our galaxy. “No previous high-energy mission has had the imaging resolution of NuSTAR,” Stern told Universe Today. ”Our order-of-magnitude increase in image sharpness means that we’re able to map out that very rich region of the sky, which is populated by supernovae remnants, X-ray binaries, as well as the big black hole at the center of our Galaxy, Sagittarius A* (pronounced “A-star).”
NuSTAR identifies new black hole candidates (in blue) in the COSMOS field. The discoveries in the image above are overlayed on previous black holes spotted by Chandra in the same field, which are denoted in red and green. (Credit-NASA/JPL-Caltech/Yale University).
Yale University researcher Francesca Civano also presented a new image from NuSTAR depicting black holes that were previously obscured from view. NuSTAR is especially suited for this, gazing into the hearts of energetic galaxies that are invisible to observatories such Chandra or XMM-Newton. The image presented covers the area of Hubble’s Cosmic Evolution Survey, known as COSMOS in the constellation Sextans. In fact, Civano notes that NuSTAR has already seen the highest number of obscured black hole candidates to date.
“This is a hot topic in astronomy,” Civano said in a recent press release. “We want to understand how black holes grew and the degree to which they are obscured.”
To this end, NuSTAR researchers are taking a stacked “wedding cake” approach, looking at successively larger slices of the sky from previous surveys. These include looking at the quarter degree field of the Great Observatories Origins Deep Survey (GOOD-S) for 18 days, the two degree wide COSMOS field for 36 days, and the large four degree Swift-BAT fields for 40 day periods hunting for serendipitous sources.
Interestingly, NuSTAR has also opened the window on the hard X-ray background that permeates the universe as well. This peaks in the 20-30 KeV range, and is the combination of the X-ray emissions of millions of black holes.
“For several decades already, we’ve known what the sum total emission of the sky is across the X-ray regime,” Stern told Universe Today. “The shape of this cosmic X-ray background peaks strongly in the NuSTAR range. The most likely interpretation is that there are a large number of obscured black holes out there, objects that are hard to find in other energy bands. NuSTAR should find these sources.”
And NuSTAR may just represent the beginning of a new era in X-ray astronomy. ESA is moving ahead with its next generation flagship X-ray mission, known as Athena+, set to launch sometime next decade. Ideas abound for wide-field imagers and X-ray polarimeters, and one day, we may see a successor to NuSTAR dubbed the High-Energy X-ray Probe or (HEX-P) make it into space.
But for now, expect some great science out of NuSTAR, as it unlocks the secrets of the X-ray universe!

Phone booths. You know, those things that Superman used to change into his cape and tights. According to news reports, the last phone booths in use in the US will be decommissioned and hauled away sometime this year. If you’ve ever had the chance to actually use one of these communication relics, you know how cramped they are inside. But they provide a good size comparison to the tiny crew quarters on board the International Space Station.
In this new video, Japanese astronaut and Expedition 38 Flight Engineer Koichi Wakata provides a tour of the crew quarters inside the International Space Station’s Harmony node where there are four individual living spaces. They include a sleeping bag, laptop computers and gear for communicating with family members.
What’s the oldest thing you’ve ever held in your hand? A piece of petrified wood? A fossilized trilobite? A chunk of glacier-carved granite? Those are some pretty old things, sure, but there are even older objects to be found across the world… that came from out of this world. And thanks to “Meteorite Men” co-host, author, and educator Geoff Notkin and his company Aerolite Meteorites, you can own a truly ancient piece of the Solar System that can date back over 4.5 billion years.
Founded in 2005, Aerolite (which is an archaic term for meteorite) offers many different varieties of meteorites for sale, from gorgeous specimens worthy of a world-class museum to smaller fragments that you could proudly — and economically — display on your desk. Recently I had the opportunity to talk in depth with Geoff about Aerolite and his life’s work as a meteorite collector and dealer. Here are some of the fascinating things he had to say…
So Geoff, what initially got you interested in meteorites and finding them for yourself?
“It’s been a lifelong passion for me, but I’m lucky in that I can really put my finger on a specific event when I was a kid and that was my mother taking me to the Geological Museum in London when I was six or seven… I was already a rock hound, I loved collecting fossils, and my dad was a very keen amateur astronomer. And so I had this love of astronomy and this fascination with other worlds for as long as I can remember. I’m a very tactile person; I’m very hands-on. I like to know how things work… I want to know all the bits and pieces. I was frustrated a bit, because I wanted to know more about astronomy. I could see all these planets and places through the ‘scope, but I couldn’t touch them. But I could touch rocks and fossils.
“So I’m six or seven years old, and I’m on the second floor of the Museum in the Hall of Rocks and Minerals. And at the back was this small display area that’s very dark. And you walked through an arch, it’s almost like walking into a cave. And it was very low light back there, and that was the meteorite collection.
“There were a couple of large meteorites on stands, and in those days — it was the late 60s — security wasn’t the issue that it is today. So you could touch the big specimens, and so I put my hands on these giant meteorites and I was absolutely enthralled. And I had this sort of epiphany: meteorites were the locus between my two interests, astronomy and rock-hounding. Because they’re rocks… they’re rock samples from outer space. I promised myself as a kid that one day I would have an actual meteorite.
“By finding or owning meteorites, you are forging a solid and tangible connection with astronomy.”
“Of course at the time there was no meteorite business, no meteorite magazines, there was no network of collectors like there is today. Back in the late 60s when I gave myself this challenge it was like saying I was going to start my own space program! But not only did it come true, it’s become my career.”
What makes Aerolite such a great place to buy meteorites?
“I think the caring for the subject matter really shows on the website. We have the best photography in the entire meteorite industry. I think we have the largest selection… we certainly spend a great deal of time discussing the history and importance of pieces… every single meteorite on our website has a detailed description and in most cases multiple photographs. My view is if you’re going to do something, you should really do it to the best of your ability. We don’t cut any corners, we don’t sell anything unless we’re one hundred percent sure of what it is and where it came from.
“I want buyers and visitors to look at the website and share my sense of wonder about meteorites. I think meteorites are the most wonderful things in existence, they’re actual visitors from outer space — they’re inanimate aliens that have landed on our planet.”
“We do this because we want to share our passion. We stand by every piece that we sell.”
How can people be sure they are getting actual meteorites (and not just funny-looking rocks?)
“This is something that’s more important to pay attention to now than ever. Are there fakes, are there shady people? Yes and yes. If you go on eBay at any given time you will find numerous pieces that are being offered for sale that are either not meteorites at all or are one thing being passed off as another thing. Sometimes this is malicious, sometimes people just don’t know any better. So the best way to buy a meteorite and know that it’s real is to buy from a respected dealer who has a solid history in the field.
“I’m by no means the only person who does this. There are a number of very well-established dealers around the world, and a good place to start is the International Meteorite Collectors Association(of which Geoff is a member) which is an international group with hundreds of members — collectors and dealers… it’s sort of a watchdog group that tries to maintain high standards of integrity in the field.
“My company has a very strict policy of never offering anything that’s questionable.”
“I see fakes all the time,” Geoff added. “On eBay, on websites, in newspaper ads… you do have to be careful. My company has a very strict policy of never offering anything that’s questionable. And we do get offered questionable things. There are some countries that have strict policies about exporting meteorites — Australia and Canada being two of them — and we work very closely with academia in both countries, and we have legally exported meteorites from those countries. Not only do we abide by international regulations, we actively support them.”
So you not only offer meteorites for sale to the general public, but you also donate to schools and museums.
“We work very closely with most of the world’s major meteorite institutions. I have provided specimens to the American Museum of Natural History in New York, the British Museum of Natural History in London, the Vienna Museum of Natural History, the Center for Meteorite Studies… we work with almost everyone. When we find something that is new or different or exciting, we always donate a piece or pieces to our colleagues in academia. It’s just the right thing, it’s the right thing to do if you discover something important to make it available to science.
“Most universities and museums don’t have acquisitions budgets and can’t afford to buy things that they might like to have. In return they classify the meteorites that we found, and they go into the permanent literature and become more valuable as a result. A meteorite with a history and a name and classification is worth more than a random meteorite that somebody just found in a desert. So everybody benefits, it’s a really good match.”
In other words, you really are making a contribution to science as opposed to just “looting.”
“Exactly. And I have, a very few times, gotten emails from disgruntled viewers who didn’t understand what we were doing, saying ‘what makes you think it’s okay to come to Australia and take our meteorites,’ for example. So I wrote a very courteous email back saying that we were in Australia with the express permission and cooperation of the Australian park services and one of the senior park rangers was there with us. And not only did we follow the proper procedure in having those specimens exported from Australia, I donated rare meteorites to collections just as a ‘thank you’ for working with us. It wasn’t a trade, it was a thank you. So everywhere we go, whatever we do, we try and leave a good impression.”
Geoff added, “I do this out of love… this isn’t the best way to make a living! Being a meteorite hunter is probably not the best capital return on your time but it’s a very exciting and rewarding life in every other way.”
And thus, by buying meteorites from Aerolite, customers aren’t just helping pay for your expeditions and your work but also supporting research and education too.
“People who purchase from us are really participating in the growth of this science. Also, something very near and dear to my heart is science education for kids. You know that I am the host of an educational series called STEM Journals, which is a very — I think — amusing, entertaining, funny, fast-paced look at science, technology, engineering, and math topics. But you can’t make a living doing television shows like that. This is a labor of love… we do it because we think it’s important. If I didn’t have a commercial meteorite company to help underwrite the costs of educational programming and educational books, we just couldn’t do it. It’s as simple as that.
“So we always try to give back. That’s why I speak at schools and universities and give away meteorites to deserving kids at gem shows… because it was done to me when I was seven years old. The look of wonder you see on a kid’s face when you connect with them and they start to grasp the wonder of science… that’s something they’ll never forget.”
That’s great. And it sounds like you haven’t forgotten it yet either!
“I must say after all these years, I’ve been doing this close to full time for nearly twenty years and you never lose the amazement and the wonder of when a meteorite’s found or uncovered. I never go ‘oh, jeez, it’s just another billion-year-old space rock that fell to Earth!’ So it is a privilege to be in a work field where almost daily something wondrous happens.”
As we here at Universe Today know, when it concerns space that’s a common occurrence!
“Exactly!”
One last thing Geoff… do you think we’ll ever run out of meteorites?
“The meteorite collecting field has grown tremendously in the past ten years, and Meteorite Men is part of that. There is a finite supply of meteorites. Of course there are more landing all the time, but not enough to replenish the demand. Periodically there is a new very large discovery made, such as the Gebil Kamil iron in Egypt a couple of years ago. But what is happening is a significant increase in price and a decrease in selection, so some of the real staples we used to see… you can’t get them anymore.
“Still, people who want a meteorite collection, now is a great time for them to be buying because there are more meteorites available than in the past — but it’s not going to stay that way for very long. It’s like any other collectible that has a finite supply.”
Makes sense… I’ll take that as ‘inside advice’ to place an order soon!

WALLOPS ISLAND, VA – A private Antares rocket thundered off a Virginia launch pad today (Jan. 9) bound for the International Space Station on a breakthrough mission that marks the second successful commercial rocket launch by an American aerospace company this week – a feat that’s sure to send shock waves reverberating around the globe as well as providing an absolutely crucial life line to the station.
The majestic blastoff of Orbital Science’s Antares rocket took place from a beach side pad at NASA’s Wallop’s Flight Facility along the eastern shore of Virginia, Thursday, at 1:07 p.m. EST.
A flock of birds flew by just as Antares soared off the pad – see my lucky shot above.
The milestone flight was conducted under Orbital’s $1.9 Billion contract to NASA as the firm’s first operational cargo delivery flight to the ISS using their own developed Cygnus resupply vehicle.
“Today’s launch gives the cargo capability to keep the station going,” said Frank Culbertson, executive vice president and general manager of Orbital’s advanced spaceflight programs group, and former Space Shuttle commander.
“Everything was right on the money.”
And with the ISS lifetime in Earth orbit now newly extended by the Obama Administration to 2024, the resupply freighters pioneered by Orbital Sciences and SpaceX – in partnership with NASA – are even more important than ever before to keep the station well stocked and humming with an ever increasing array of research projects.

The goal was to restore America’s cargo and crew capabilities to low Earth orbit and the ISS that was totally lost following the forced retirement of NASA’s Space Shuttles.
Cygnus is packed chock full with a myriad of science experiments for dozens of new NASA science investigations as well as two dozen student science experiments from school across the country.

Both the terrestrial and space weather forecasts improved dramatically in the final hours of the countdown and cooperated to allow today’s magnificent Antares launch.
Furthermore, it marks a grand success for the innovative US strategy of forging low cost, reliable and effective access to space by handing the task of building the rockets and cargo vehicles to US commercial companies for routine jobs in Earth orbit while NASA focuses on investing in deep space exploration.
“Today’s launch demonstrates how our strategic investments in the American commercial spaceflight industry are helping create new jobs here at home and keep the United States the world leader in space exploration,” NASA Administrator Charles Bolden said in a NASA statement.
“American astronauts have been living and working continuously in space for the past 13 years on board the International Space Station, and we’re once again sending them supplies launched from U.S. soil.”
“In addition to the supplies, the passion and hard work of many researchers and students are being carried by Cygnus today. I congratulate Orbital and the NASA teams that made this resupply mission possible.”

The fourth launch attempt was finally the charm after a trio of postponements since mid- December 2013 to fix the malfunctioning cooling system on the station, unprecedented frigid weather and then an unexpected blast of solar radiation from the Sun on Tuesday (Jan. 7) that could have fried the delicate electronics controlling the rockets ascent with disastrous consequences.

Both the Antares and Cygnus are private vehicles built by Orbital Sciences under a $1.9 Billion supply contract with NASA to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware to the ISS.

Both the Orbital Sciences Antares/Cygnus and SpaceX Falcon 9/Dragon vehicles were developed from the start with seed money from NASA in a public-private partnership.
The flight is designated the Orbital-1, or Orb-1 mission.
A total of eight Antares/Cygnus missions to the space station are scheduled over the next two to three years by Orbital under its Commercial Resupply Services (CRS) contract with NASA.
Two additional Antares/Cygnus flight are slated for this year.
They are slated to lift off around May 1 and early October, said Culbertson.
This launch follows a pair of successful launches in 2013, including the initial test launch in April and the 1st demonstration launch to the ISS in September.
Cygnus is loaded with approximately 2,780 pounds / 1,261 kilograms of cargo for the ISS crew for NASA including science experiments, computer supplies, spacewalk tools, food, water, clothing and experimental hardware.
33 cubesats are also on board that will be deployed over time by the 6 person crew living aboard the ISS.
Among the research items packed aboard the Antares/Cygnus flight are an experiment to study the effectiveness of antibiotics in space and a batch of 23 student experiments involving life sciences topics ranging from amoeba reproduction to calcium in the bones to salamanders.
The student experiments selected are from middle school and high school teams from Michigan, Texas, Colorado, and Washington, DC.

There is also an ant farm aboard with ant colonies from Colorado, North Carolina and of course host state Virginia too. The goal is to study ant behavior in space in zero gravity and compare that to ants on Earth living under normal gravity.
Cygnus will rendezvous with the station on Sunday, Jan 12.
Expedition 38 crew members aboard the station will grapple Cygnus with the stations robotic arm Sunday at 6:02 a.m. EDT.
NASA TV will provide live coverage of Sunday’s docking.

Amazing, the things a birds-eye view allows you to see. Here’s a color image from the HiRISE camera on board the Mars Reconnaissance Orbiter showing the tracks of the Curiosity rover. In this most recent HiRISE image of the MSL rover, the tracks are visible from Yellowknife Bay to its location on 11 December 2013, several kilometers to the southwest. Even though some of these tracks are more than a year old, they are still visible.
As HiRISE team member Christian Schaller said via Twitter, “Take only pictures; leave only footprints.” In this case, HiRISE took the pictures while MSL left the footprints!
HiRISE principal investigator Alfred McEwen explained the image: “Curiosity is progressing from the bright dust-covered area to a region with a darker surface, where saltating sand keeps the surface relatively free of dust. The scenery seen by the rover will be getting more interesting as it progresses toward Mount Sharp.”
See a black and white image below, where you can actually see Curiosity, too:

On January 20, 2014 it will be time for the snoozing Rosetta spacecraft to awaken from 31 months of hibernation. Through an online contest, ESA has been looking for a little help in sending a wake-up call to the spacecraft, which will be 673 million kilometers from Earth. The “Wake Up Rosetta!” video contest has yielded some heartwarming, funny, and creative videos from families, school children and more. Here are a few of our favorites, and you can go to the contest’s Facebook page to find out how to submit your own video, as well as see more videos and vote for your favorite.
The top ten vote-getting videos will be transmitted out to Rosetta via one of ESA’s deep-space tracking stations, and there are additional prizes as well, including the top two video creators will be invited to the control center in Darmstadt, Germany for when the Philae lander attempts landing on comet 67P/Churyumov–Gerasimenko in November 2014 after latching on with a harpoon.
ESA themselves have come up with a video story of the Rosetta mission and how it will be awakened:
