NASA WALLOPS FLIGHT FACILITY, VA – Moments after a seemingly glorious liftoff, an Orbital Sciences Corp. commercial Antares rocket suffered a catastrophic failure and exploded into a spectacular aerial fireball over the launch pad at NASA’s Wallops Flight Facility on the eastern shore of Virginia that doomed the mission bound for the International Space Station on Tuesday, October 28.
The 14 story tall Antares rocket blasted off at 6:22 p.m. EDT from the beachside Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops on only its 5th launch overall.
I witnessed and photographed the launch from the media viewing area on site at NASA Wallops from a distance of about 1.8 miles away.
This story is being updated. See a gallery of photos herein.
Antares was carrying Orbital’s privately developed Cygnus pressurized cargo freighter loaded with nearly 5000 pounds (2200 kg) of science experiments, research instruments, crew provisions, spare parts, spacewalk and computer equipment and gear on a critical resupply mission dubbed Orb-3 bound for the International Space Station (ISS).

It was the heaviest cargo load yet lofted by a Cygnus. Some 800 pounds additional cargo was loaded on board compared to earlier flights. That was enabled by using the more powerful ATK CASTOR 30XL engine to power the second stage for the first time.
Everything appeared normal at first. But within about five seconds or so there was obviously a serious mishap as the rocket was no longer ascending. It was just frozen in time. And I was looking directly at the launch, not through the viewfinder of my cameras.
Something was noticeably amiss almost instantly as the rocket climbed only very slowly, barely clearing the tower it seemed to me. The rocket failed to emerge from the normal huge plume of smoke and ash that’s purposely deflected away by the flame trench at the base of the pad.
I was stunned trying to comprehend what was happening because it was all so wrong.
It was absolutely nothing like the other Antares launches I’ve witnessed from the media site.

I knew as a scientist and journalist that I was watching a mounting disaster unfolding before my eyes.
Instead of ascending on an accelerating arc, a mammoth ball of fire, smoke and ash blew up the entire sky in front of us like a scene out of hell or war. Literally the sky was set on fire unlike anything I’ve ever witnessed.
A series of mid air explosions rocked the area. I could feel a slight pressure wave followed by a mild but noticeable heat wave passing by.
Then the rocket began to fall back to Earth. Then the ground blew up too as the rocket pieces hit the ground and exploded into a hail of smithereens in every direction.
By this time our NASA escorts starting yelling to abandon everything in place and head immediately for the buses and evacuate the area. The ground fire spread mostly to the northern portion of the pad and the expanding air borne plume also blew northwards. The ground fire was still burning over a half hour later.
Thankfully, everyone got out safe and there were no injuries due to the excellent effort by our NASA escorts trained for exactly these types of unexpected circumstances.
It’s heartbreaking for everyone’s painstaking efforts to get to the point of liftoff after years of effort to fulfill the critical need to resupply that station with the science equipment and experiments for which it was built.
More later

Ever since the Cassini space probe conducted its first flyby of Enceladus in 2005, the strange Saturnian moon has provided us with a treasure trove of images and scientific wonders. These include the jets of icy water vapor periodically bursting from its south pole, the possibility of an interior ocean – which may even harbor life – and the strange green-blue stripes located around the south pole.

NASA has taken on space missions that have taken years to reach their destination; they have more than a dozen ongoing missions throughout the Solar System and have been to comets as well. So why pay any attention to the European Space Agency’s comet mission Rosetta and their new short film, “Ambition”?
‘Ambition’ might accomplish more in 7 minutes than ‘Gravity’ did in 90.
‘Ambition’ is a 7 minute movie created for ESA and Rosetta, shot on location in Iceland, directed by Oscar-winning Tomek Baginski, and stars Aidan Gillen—Littlefinger of ‘Game of Thrones.’ It is an abstraction of the near future where humans have become demigods. An apprentice is working to merge her understanding of existence with her powers to create. And her master steps in to assure she is truly ready to take the next step.
In the reality of today, we struggle to find grounding for the quest and discoveries that make up our lives on a daily basis. Yet, as the Ebola outbreak or the Middle East crisis reminds us, we are far from breaking away. Such events are like the opening scene of ‘Ambition’ when the apprentice’s work explodes in her face.
The ancient Greeks also took great leaps beyond all the surrounding cultures. They imagined themselves as capable of being demigods. Achilles and Heracles were born from their contact with the gods but they remained fallible and mortal.

But consider the abstraction of the Rosetta mission in light of NASA’s ambitions. As an American viewing the European short film, it reminds me that we are not unlike the ancient Greeks. We have seen the heights of our powers and ability to repel and conquer our enemies, and enrich our country. But we stand manifold vulnerable.
In ‘Ambition’ and Rosetta, America can see our European cousins stepping ahead of us. The reality of the Rosetta mission is that a generation ago – 25 years — we had a mission as ambitious called Comet Rendezvous Asteroid Flyby (CRAF). From the minds within NASA and JPL, twin missions were born. They were of the Mariner Mark II spacecraft design for deep space. One was to Saturn and the other – CRAF was to a comet. CRAF was rejected by congress and became an accepted sacrifice by NASA in order to save its twin, the Cassini mission.
The short film ‘Ambition’ and the Rosetta mission is a reminder of what American ambition accomplished in the 60’s – Apollo, and the 70s – the Viking Landers, but then it began to falter in the 80s. The ambition of the Europeans did not lose site of the importance of comets. They are perhaps the ultimate Rosetta stones of our star system. They are unmitigated remnants of what created our planet billions of years ago unlike the asteroids that remained close to the Sun and were altered by its heat and many collisions.

Our cousins picked up a scepter that we dropped and we should take notice that the best that Europe spawned in the last century – the abstract art of Picasso and Stravinsky, rocketry, and jet travel — remains alive today. Europe had the vision to continue a quest to something quite abstract, a comet, while we chose something bigger and more self-evident, Saturn and Titan.
‘Ambition’ shows us the forces at work in and around ESA. They blend the arts with the sciences to bend our minds and force us to imagine what next and why. There have been American epoch films that bend our minds, but yet sometimes it seems we hold back our innate drive to discover and venture out.
NASA recently created a 7 minute film of a harsh reality, the challenge of landing safely on Mars. ESA and Rosetta’s short film reminds us that we are not alone in the quest for knowledge and discovery, both of which set the stage for new growth and invention. America needs to take heed so that we do not wait until we reach the moment when an arrow pierces our heel as with Achilles and we succumb to our challengers.

Getting to the International Space Station is no easy task. Generally speaking, it involves loading up a space capsule with several tons of cargo and then expending millions of liters of fuel to get it into orbit. This process is time consuming and very expensive. And what if astronauts want to send some things back? Currently, their only option for return capability is provided by the same cargo capsules that are sent up to them.

NASA WALLOPS FLIGHT FACILITY, VA – An Orbital Sciences Corp. commercial Antares rocket was given the GO for its first night launch on Oct. 27, following a launch readiness review on Sunday, Oct. 26, between managers from Orbital Sciences Corp. of Dulles, Virginia, and NASA.
The rocket was rolled to the launch pad and erected. Technicians are putting the final touches on the rocket to prepare it for flight to the International Space Station (ISS).
NASA and Orbital Sciences are targeting Antares for blastoff at 6:45 p.m. EDT on Oct. 27 from beachside Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops Island Flight Facility on Virginia’s eastern shore.
There is a 10 minute launch window to get Antares off the ground as the launch pad moves into the plane of the space stations orbit. The slightly longer launch window is due to the extra thrust available from using a new, more powerful ATK built upper stage engine.

The rare spectacle of a night launch within view of tens of millions could WOW hordes of US East Coast residents in densely populated areas up and down the Atlantic shoreline – weather permitting.
The current forecast calls for an almost unheard of 98% chance of favorable weather conditions at launch time.
Depending on local weather conditions, the Antares blastoff will be visible along much of the US eastern seaboard – stretching from Maine to South Carolina.

This map shows the rough time at which you can first expect to see Antares after it is launched on Oct. 27, 2014. It represents the time at which the rocket will reach 5 degrees above the horizon and varies depending on your location . We have selected 5 degrees as it is unlikely that you’ll be able to view the rocket when it is below 5 degrees due to buildings, vegetation, and other terrain features. However, depending on your local conditions the actual time you see the rocket may be earlier or later. As an example, using this map when observing from Washington, DC shows that Antares will reach 5 degrees above the horizon approximately 117 seconds after launch (L + 117 sec).

This is the heaviest cargo load yet lofted by a Cygnus. Some 800 pounds additional cargo is loaded on board compared to earlier flights, that’s enabled by using the more powerful ATK CASTOR 30XL second stage for the first time.
Research gear and experiments account for about 1600 pounds (720 kg), or about one third of Cygnus total cargo load.
Among the items aboard are 32 cubesats and deployers, a 6000 psi high pressure replacement nitrogen tank needed for spacewalks from the Quest airlock, experiments enabling the first space-based observations of meteors entering Earth’s atmosphere, determination of how blood flows from the brain to the heart in the absence of gravity, investigations on the impact of space travel on both the human immune system and an individual’s microbiome, the collection of microbes that live in and on the human body, and student science investigations from the SSEP/NCESSE.
“There is nothing more exciting than spaceflight,” said Frank Culbertson, Orbital’s executive vice president of the advanced programs group, at a pre-launch briefing at NASA Wallops.
“It is important to inspire the next generation of scientists. We need to keep the kids inspired to study math and science and keep going back to space. If we stop going to space, it will be very hard to restart.”

This Cygnus resupply module, dubbed “SS Deke Slayton,” honors one of America’s original Mercury 7 astronauts, Donald “Deke” K. Slayton. He flew on the Apollo-Soyuz Test Project mission in 1975 and championed commercial space endeavors after retiring from NASA in 1982. Slayton passed away in 1993.
The Orbital-3, or Orb-3, mission is the third of eight cargo resupply missions to the ISS through 2016 under the NASA Commercial Resupply Services (CRS) contract award valued at $1.9 Billion.
Orbital Sciences is under contract to deliver 20,000 kilograms of research experiments, crew provisions, spare parts and hardware for the eight ISS flight.

A space-weathered @SpaceX #Dragon looking great moments before release today. Credit: NASA/Reid Wiseman
Concluding a busy five week mission, the SpaceX Dragon CRS-4 commercial cargo ship departed the International Space Station (ISS) this morning, Oct. 25, after delivering a slew of some 2.5 tons of ground breaking science experiments and critical supplies that also inaugurated a new era in Earth science at the massive orbiting outpost following installation of the ISS-RapidScat payload.
Dragon was released from the snares of the station’s robotic arm at 9: 57 a.m. EDT while soaring some 250 mi (400 km) over the northwest coast of Australia.
It returned safely to Earth with a splashdown in the Pacific Ocean some six hours later, capping the fourth of SpaceX’s twelve contracted station resupply missions for NASA through 2016.
“The Dragon is free!” exclaimed NASA commentator Rob Navias during a live broadcast on NASA TV following the ungrappling this morning. “The release was very clean.”

The private resupply ship was loaded for return to Earth with more than 3,276 pounds of NASA cargo and science samples from the station crew’s investigations on “human research, biology and biotechnology studies, physical science investigations, and education activities sponsored by NASA and the Center for the Advancement of Science in Space, the nonprofit organization responsible for managing research aboard the U.S. national laboratory portion of the space station,” said NASA.
The release set up a quick series of three burns by the ship’s Draco thrusters designed to carry Dragon safely away from the station.
NASA astronauts Reid Wiseman and Butch Wilmore quickly retracted the arm working from their robotics workstation in the domed Cupola module.
“Thanks for the help down there,” the astronauts radioed. “It was a great day.”

The first burn took place a minute later at about 9:58 a.m. EDT and the second at about 10:00 a.m. A yaw maneuver at 10:05 a.m. set up the orientation required for the third burn at about 10:08 a.m.
Dragon moved away quickly during the nighttime release and was already outside the Keep Out Sphere (KOS), an imaginary bubble surrounding the station at a distance of 200 m. It disappeared quickly in the dark and was barely visible within minutes.
“The propulsion systems are in good shape,” said Navias. “All systems on Dragon are functioning perfectly.”
With Dragon safely gone following the trio of burns, the next major event was the deorbit burn at 2:43 p.m. EDT at a distance of about 90 statute miles from the station.
Dragon slipped out of orbit. After surviving the scorching heat of reentry through the Earth’s atmosphere, the ship sequentially deployed its drogue chutes and three main parachutes at about 3:30 p.m.
Splashdown in the Pacific Ocean occurred as expected at about 3:39 p.m., approximately 265 miles west of the Baja peninsula.
Dragon is the only vehicle that can return intact from the ISS with a substantial load of cargo and is carrying critical science samples for distribution to researchers.
Today’s Dragon departure starts a week of heavy traffic of comings and goings to the ISS involving a series of US and Russian unmanned cargo ships.

The Orbital Sciences Antares rocket with the commercial Cygnus cargo freighter is set to launch on Monday, Oct. 27, from NASA Wallops, VA. It will dock at the ISS on Nov. 2 at the Earth-facing port on the Harmony module just vacated by Dragon.
Russia’s Progress 56 unmanned cargo ship will also undock on Oct. 27. And Progress 57 will launch from Baikonur on Wednesday, Oct 29.

Dragon was successfully berthed at the Harmony module on Sept. 23, 2014.
Among the nearly 5000 pounds of cargo hauled up by Dragon was as an Earth observation platform named ISS-RapidScat loaded in the unpressurized trunk section.
Also loaded aboard were a slew of science experiments, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.
It also carried the first 3-D printer to space for the first such space based studies ever attempted by the astronaut crews. The printer will remain at the station for at least the next two years.
20 mice housed in a special rodent habitat were also aboard, as well as fruit flies.
The ISS Rapid Scatterometer, or ISS-RapidScat, is NASA’s first research payload aimed at conducting near global Earth science from the station’s exterior and will be augmented with others in coming years.

The successful installation and activation of the ISS-RapidScat science instrument on the exterior of Europe’s Columbus module in late September and early October inaugurated a new era in space station science.
RapidScat is designed to monitor ocean winds for climate research, weather predictions, and hurricane monitoring.
The 1280 pound (580 kilogram) experimental instrument is already collecting its first science data following its recent power-on and activation at the station.

“This mission enabled research critical to achieving NASA’s goal of long-duration human spaceflight in deep space,” said Sam Scimemi, director of the International Space Station division at NASA Headquarters.
“The delivery of the ISS RapidScatterometer advances our understanding of Earth science, and the 3-D printer will enable a critical technology demonstration. Investigations in the returned cargo could aid in the development of more efficient solar cells and semiconductor-based electronics, the development of plants better suited for space, and improvements in sustainable agriculture.”
The next SpacX cargo Dragon on the CRS-5 mission is slated for launch no earlier then Dec. 9.

Will cubesats develop a new technological branch of astronomy? Goddard engineers are taking the necessary steps to make cubesat sized telescopes a reality. (Credit: NASA, UniverseToday/TRR)
One doesn’t take two cubesats and rub them together to make static electricity. Rather, you send them on a brief space voyage to low-earth orbit (LEO) and space them apart some distance and voilà, you have a telescope. That is the plan of NASA’s Goddard Space Flight Center engineers and also what has been imagined by several others.
Cubesats are one of the big crazes in the new space industry. But nearly all that have flown to-date are simple rudderless cubes taking photos when they are oriented correctly. The GSFC engineers are planning to give two cubes substantial control of their positions relative to each other and to the Universe surrounding them. With one holding a telescope and the other a disk to blot out the bright sun, their cubesat telescope will do what not even the Hubble Space Telescope is capable of and for far less money.
Semper (left), Calhoun, and Shah are advancing the technologies needed to create a virtual telescope that they plan to demonstrate on two CubeSats. (Image/Caption Credit: NASA/W. Hrybyk)
The 1U, the 3U, the 9U – these are all cubesats of different sizes. They all have in common the unit size of 1. A 1U cubesat is 10 x 10 x 10 centimeters cubed. A cube of this size will hold one liter of water (about one quart) which is one kilogram by weight. Or replace that water with hydrazine and you have very close to 1 kilogram of mono-propellent rocket fuel which can take a cubestat places.
GSFC aerospace engineers, led by Neerav Shah, don’t want to go far, they just want to look at things far away using two cubesats. Their design will use one as a telescope – some optics and a good detector –and the other cubesat will stand off about 20 meters, as they plan, and function as a coronagraph. The coronagraph cubesat will function as a sun mask, an occulting disk to block out the bright rays from the surface of the Sun so that the cubesat telescope can look with high resolution at the corona and the edge of the Sun. To these engineers, the challenge is keeping the two cubesats accurately aligned and pointing at their target.
Only dedicated Sun observing space telescopes such as SDO, STEREO and SOHO are capable of blocking out the Sun, but their coronagraphs are limited. Separating the coronagraph farther from the optics markedly improves how closely one can look at the edge of a bright object. With the corongraph mask closer to the optics, more bright light will still reach the optics and detectors and flood out what you really want to see. The technology Shah and his colleagues develop can be a pathfinder for future space telescopes that will search for distant planets around other stars – also using a coronagraph to reveal the otherwise hidden planets.
The engineers have received a $8.6-million investment from the Defense Advanced Research Project Agency (DARPA) and are working in collaboration with the Maryland-based Emergent Space Technologies.

The challenge of GSFC engineers is giving two small cubesats guidance, navigation, and control (GN&C) as good as any standard spacecraft that has flown. They plan on using off-the-shelf technology and there are many small and even large companies developing and selling cubesat parts.
This is a sorting out period for the cubesat sector, if you will, of the new space industry. Sorting through the off-the-shelf components, the GSFC engineers led by Shah will pick the best in class. The parts they need are things like tiny sun sensors and star sensors, laser beams and tiny detectors of those beams, accelerometers, tiny gyroscopes or momentum wheels and also small propulsion systems. The cubesat industry is pretty close to having all these ready as standard issue. The question then is what do you do with tiny satellites in low-Earth orbit (LEO). Telescopes for earth-observing are already making headway and scopes for astronomy are next. There are also plans to venture out to interplanetary space with tiny and capable cubesat space probes.
Whether one can sustain a profit for a company built on cubesats remains a big question. Right now those building cubesats to customer specs are making a profit and those making the tiny picks and shovels for cubesats are making profits. The little industry may be overbuilt which in economic parlance might be only natural. Many small startups will fail. However, for researchers at universities and research organizations like NASA, cubesats have staying power because they reduce cost by their low mass and size, and the low cost of the components to make them function. The GSFC effort will determine how quickly cubesats begin to do real work in the field of astronomy. Controlling attitude and adding propulsion is the next big thing in cubesat development.

A new mystery of Titan has been uncovered by astronomers using their latest asset in the high altitude desert of Chile. Using the now fully deployed Atacama Large Millimeter Array (ALMA) telescope in Chile, astronomers moved from observing comets to Titan. A single 3 minute observation revealed organic molecules that are askew in the atmosphere of Titan. The molecules in question should be smoothly distributed across the atmosphere, but they are not.
The Cassini/Huygens spacecraft at the Saturn system has been revealing the oddities of Titan to us, with its lakes and rain clouds of methane, and an atmosphere thicker than Earth’s. But the new observations by ALMA of Titan underscore how much more can be learned about Titan and also how incredible the ALMA array is.

The ALMA astronomers called it a “brief 3 minute snapshot of Titan.” They found zones of organic molecules offset from the Titan polar regions. The molecules observed were hydrogen isocyanide (HNC) and cyanoacetylene (HC3N). It is a complete surprise to the astrochemist Martin Cordiner from NASA Goddard Space Flight Center in Greenbelt, Maryland. Cordiner is the lead author of the work published in the latest release of Astrophysical Journal Letters.
The NASA Goddard press release states, “At the highest altitudes, the gas pockets appeared to be shifted away from the poles. These off-pole locations are unexpected because the fast-moving winds in Titan’s middle atmosphere move in an east–west direction, forming zones similar to Jupiter’s bands, though much less pronounced. Within each zone, the atmospheric gases should, for the most part, be thoroughly mixed.”
When one hears there is a strange, skewed combination of organic compounds somewhere, the first thing to come to mind is life. However, the astrochemists in this study are not concluding that they found a signature of life. There are, in fact, other explanations that involve simpler forces of nature. The Sun and Saturn’s magnetic field deliver light and energized particles to Titan’s atmosphere. This energy causes the formation of complex organics in the Titan atmosphere. But how these two molecules – HNC and HC3N – came to have a skewed distribution is, as the astrochemists said, “very intriguing.” Cordiner stated, “This is an unexpected and potentially groundbreaking discovery… a fascinating new problem.”
The press release from the National Radio Astronomy Observatory states, “studying this complex chemistry may provide insights into the properties of Earth’s very early atmosphere.” Additionally, the new observations add to understanding Titan – a second data point (after Earth) for understanding organics of exo-planets, which may number in the hundreds of billions beyond our solar system within our Milky Way galaxy. Astronomers need more data points in order to sift through the many exo-planets that will be observed and harbor organic compounds. With Titan and Earth, astronomers will have points of comparison to determine what is happening on distant exo-planets, whether it’s life or not.

The report of this new and brief observation also underscores the new astronomical asset in the altitudes of Chile. ALMA represents the state of the art of millimeter and sub-millimeter astronomy. This field of astronomy holds a lot of promise. Back around 1980, at the Kitt Peak National Observatory in Arizona, alongside the great visible light telescopes, there was an oddity, a millimeter wavelength dish. That dish was the beginning of radio astronomy in the 1 – 10 millimeter wavelength range. Millimeter astronomy is only about 35 years old. These wavelengths stand at the edge of the far infrared and include many light emissions and absorptions from cold objects which often include molecules and particularly organics. The ALMA array has 10 times more resolving power than the Hubble space telescope.
The Earth’s atmosphere stands in the way of observing the Universe in these wavelengths. By no coincidence our eyes evolved to see in the visible light spectrum. It is a very narrow band, and it means that there is a great, wide world of light waves to explore with different detectors than just our eyes.

In the millimeter range of wavelengths, water, oxygen, and nitrogen are big absorbers. Some wavelengths in the millimeter range are completely absorbed. So there are windows in this range. ALMA is designed to look at those wavelengths that are accessible from the ground. The Chajnantor plateau in the Atacama desert at 5000 meters (16,400 ft) provides the driest, clearest location in the world for millimeter astronomy outside of the high altitude regions of the Antarctic.
At high altitude and over this particular desert, there is very little atmospheric water. ALMA consists of 66 12 meter (39 ft) and 7 meter (23 ft) dishes. However, it wasn’t just finding a good location that made ALMA. The 35 year history of millimeter-wavelength astronomy has been a catch up game. Detecting these wavelengths required very sensitive detectors – low noise in the electronics. The steady improvement in solid-state electronics from the late 70s to today and the development of cryostats to maintain low temperatures have made the new observations of Titan possible. These are observations that Cassini at 1000 kilometers from Titan could not do but ALMA at 1.25 billion kilometers (775 million miles) away could.

The ALMA transporter vehicle carefully carries the state-of-the-art antenna, with a diameter of 12 metres and a weight of about 100 tons, on the 28 km journey to the Array Operations Site, which is at an altitude of 5000 m. The antenna is designed to withstand the harsh conditions at the high site, where the extremely dry and rarefied air is ideal for ALMA’s observations of the universe at millimetre- and sub-millimetre-wavelengths.

The prototype ALMA telescope was tested at the site of the VLA in New Mexico in 2003. That prototype now stands on Kitt Peak having replaced the original millimeter wavelength dish that started this branch of astronomy in the 1980s. The first dishes arrived in 2007 followed the next year by the huge transporters for moving each dish into place at such high altitude. The German-made transporter required a cabin with an oxygen supply so that the drivers could work in the rarefied air at 5000 meters. The transporter was featured on an episode of the program Monster Moves. By 2011, test observations were taking place, and by 2013 the first science program was undertaken. This year, the full array was in place and the second science program spawned the Titan observations. Many will follow. ALMA, which can operate 24 hours per day, will remain the most powerful instrument in its class for about 10 years when another array in Africa will come on line.

Technicians at the Kennedy Space Center have completed the final major assembly work on NASA’s maiden Orion crew module slated to launch on its first unmanned orbital test flight this December, dubbed Exploration Flight Test-1 (EFT-1)
After first attaching the Launch Abort System (LAS) to the top of the capsule, engineers carefully installed a fairing composed of a set of four ogive panels over the crew module and the abort systems lower structural framework joining them together.
“The ogive panels smooth the airflow over the conical spacecraft to limit sound and vibration, which will make for a much smoother ride for the astronauts who will ride inside Orion in the future,” according to a NASA description.
Upon finishing the panel assembly work inside the Launch Abort System Facility (LASF) at NASA’s Kennedy Space Center, the teams cleared the last major hurdle before the Orion stack is rolled out to launch pad 37 in mid-November and hoisted to the top of the Delta IV Heavy rocket.

The Orion stack is comprised of the LAS, crew module (CM) and service module (SM).
The maiden blastoff of the state-of-the-art Orion spacecraft on the EFT-1 mission is slated for December 4, 2014, from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida atop the triple barreled United Launch Alliance (ULA) Delta IV Heavy booster.
Orion is NASA’s next generation human rated vehicle that will eventually carry America’s astronauts beyond Earth on voyages venturing farther into deep space than ever before – beyond the Moon to Asteroids, Mars, and other destinations in our Solar System.

The two-orbit, four and a half hour EFT-1 flight around Earth will lift the Orion spacecraft and its attached second stage to an orbital altitude of 3,600 miles, about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years. It will test the avionics and electronic systems inside the Orion spacecraft.
Then the spacecraft will travel back through the atmosphere at speeds approaching 20,000 mph and temperatures near 4,000 degrees Fahrenheit to test the heat shield, before splashing down for a parachute assisted landing in the Pacific Ocean.

The LAS plays a critically important role to ensure crew safety.
In case of an emergency situation, the LAS is designed to ignite within milliseconds to rapidly propel the astronauts inside the crew module away from the rocket and save the astronauts’ lives. The quartet of LAS abort motors would generate some 500,000 pounds of thrust to pull the capsule away from the rocket.
