After a decade of hard work, numerous twists and turns, and ups and downs, NASA’s new Orion deep space crew vehicle is finally, and officially, marching towards its maiden blastoff in less than two week’s time.
The Orion spacecraft cleared one of the final hurdles to its first launch when top managers from NASA and Lockheed Martin successfully completed a key review of the vehicle’s systems ahead of the looming Dec. 4 flight test.
Orion passed the Flight Readiness Review (FRR) on Thursday, Nov. 20, and officials announced that the spacecraft is “GO” for proceeding on the road to launch – and one day on to Mars!
The FRR is a rigorous assessment of the spacecraft, its systems, mission operations, and support functions needed to successfully complete Orion’s first voyage to space.
Lockheed Martin is the prime contractor for Orion and recently completed its fabrication in the Neil Armstrong Operations and Checkout Building at the Kennedy Space Center in September 2014.
Orion will lift off on a Delta IV Heavy rocket on its inaugural test flight to space on the uncrewed Exploration Flight Test-1 (EFT-1) mission at 7:05 a.m. EST on December 4, 2014, from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.
The United Launch Alliance Delta IV Heavy rocket is the world’s most powerful rocket and the only booster sufficiently powerful to launch the 50,000 pound Orion EFT-1 spacecraft to orbit.
The rocket was transported to pad 37 in late September. Then, on Nov. 12, this path finding Orion spacecraft was itself rolled out to the launch pad and hoisted and bolted atop the Delta IV Heavy.
The critical December test flight will pave the way for the first human missions to deep space in more than four decades since NASA’s Apollo moon landing missions ended in 1972.
To learn more about the major events and goals happening during Orion’s EFT-1 mission be sure to check out NASA’s cool new set of infographics explaining the 8 key events in my story – here.
The two-orbit, four and a half hour Orion 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.
EFT-1 will test the rocket, second stage, jettison mechanisms, as well as avionics, attitude control, computers, and electronic systems inside the Orion spacecraft.
Then the spacecraft will carry out a high speed re-entry through the atmosphere at speeds approaching 20,000 mph and scorching temperatures near 4,000 degrees Fahrenheit to test the heat shield, before splashing down for a parachute assisted landing in the Pacific Ocean.
Orion is NASA’s next generation human rated vehicle that will 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.
Watch for Ken’s ongoing Orion coverage and he’ll be onsite at KSC in the days leading up to the historic launch on Dec. 4.

In another sign of dramatically changing times since the end of NASA’s Space Shuttle program, the world famous Countdown Clock that ticked down to numerous blastoffs at the Kennedy Space Center Press Site and was ever present to billions of television viewers worldwide, has been retired.
Years of poor weather and decades of unforgiving time have visibly taken their toll on the iconic Countdown Clock beloved by space enthusiasts across the globe – as I have personally witnessed over years of reporting on launches from the KSC Press Site.
It was designed in the 1960s and has been counting down launches both manned and unmanned since the Apollo 12 moon landing mission in November 1969. And it continued through the final shuttle mission liftoff in July 2011 and a variety of unmanned NASA launches since then.
The countdown clock’s last use came just two months ago in September 2014 during the SpaceX CRS-4 launch to the ISS, which I attended along with the STS-135 launch.
The clock is located just a short walk away from another iconic NASA symbol – the Vehicle Assembly Building (VAB) – which assembled the Apollo/Saturn and Space Shuttle stacks for which it ticked down to blastoff. See photo below.
A new clock should be in place for NASA’s momentous upcoming launch of the Orion crew capsule on its inaugural unmanned test flight on Dec. 4, 2014.
Because of its age, it has become harder to replace broken pieces.
“Maintaining the clock was becoming problematic,” NASA Press spokesman Allard Beutel told Universe Today.
It displays only time in big bold digits. But of course in this new modern digital era it will be replaced by one with a modern multimedia display, similar to the screens seen at sporting venues.
“The new clock will not only be a timepiece, but be more versatile with what we can show on the digital display,” Beutel told me.
The countdown clock is a must see for journalists, dignitaries and assorted visitors alike. Absolutely everyone, and I mean everyone !! – wants a selfie or group shot with it in some amusing or charming way to remember good times throughout the ages.
And of course, nothing beats including the countdown clock and the adjacent US flag in launch pictures in some dramatic way.
Indeed the clock and flag are officially called “The Press Site: Clock and Flag Pole” and are were listed in the National Register of Historic Places on Jan. 21, 2000.
The clock was officially powered down for the last time at 3:45 p.m. EDT on Nov. 19, 2014.
“The countdown clock at Kennedy’s Press Site is considered one of the most-watched timepieces in the world and may only be second in popularity to Big Ben’s Great Clock in London, England. It also has been the backdrop for a few Hollywood movies,” noted a NASA press release announcing the impending shutdown of the iconic clock.
“It is so absolutely unique — the one and only — built for the world to watch the countdown and launch,” said Timothy M. Wright, IMCS Timing, Countdown and Photo Services. “From a historical aspect, it has been very faithful to serve its mission requirements.”
The famous landmark stands nearly 6 feet (70 inches) high, 26 feet (315 inches) wide is 3 feet deep and sits on a triangular concrete and aluminum base.
Each numerical digit (six in all) is about 4 feet high and 2 feet wide. Each digit uses 56 40-watt light bulbs, the same ones found at the local hardware store. There are 349 total light bulbs in the clock, including the +/- sign (nine) and pair of colons (four), according to a NASA statement.
The new clock will be about the same size.
Fortunately for space fans, there is some good news!
The Countdown Clock will be moved to the nearby Kennedy Space Center Visitor Complex (KSCVC) and placed on permanent display for public viewing.
Details soon!

Barely two months after being launched to the International Space Station (ISS), NASA’s first science payload aimed at conducting Earth science from the station’s exterior has started its ocean wind monitoring operations two months ahead of schedule.
Data from the ISS Rapid Scatterometer, or ISS-RapidScat, payload is now available to the world’s weather and marine forecasting agencies following the successful completion of check out and calibration activities by the mission team.
Indeed it was already producing high quality, usable data following its power-on and activation at the station in late September and has monitored recent tropical cyclones in the Atlantic and Pacific Oceans prior to the end of the current hurricane season.
RapidScat is designed to monitor ocean winds for climate research, weather predictions, and hurricane monitoring for a minimum mission duration of two years.
“RapidScat is a short mission by NASA standards,” said RapidScat Project Scientist Ernesto Rodriguez of JPL.
“Its data will be ready to help support U.S. weather forecasting needs during the tail end of the 2014 hurricane season. The dissemination of these data to the international operational weather and marine forecasting communities ensures that RapidScat’s benefits will be felt throughout the world.”
The 1280 pound (580kilogram) experimental instrument was developed by NASA’s Jet Propulsion Laboratory. It’s a cost-effective replacement to NASA’s former QuikScat satellite.
The $26 million remote sensing instrument uses radar pulses reflected from the ocean’s surface at different angles to calculate the speed and direction of winds over the ocean for the improvement of weather and marine forecasting and hurricane monitoring.
The RapidScat, payload was hauled up to the station as part of the science cargo launched aboard the commercial SpaceX Dragon CRS-4 cargo resupply mission that thundered to space on the company’s Falcon 9 rocket from Space Launch Complex-40 at Cape Canaveral Air Force Station in Florida on Sept. 21.
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.
It was robotically assembled and attached to the exterior of the station’s Columbus module using the station’s robotic arm and DEXTRE manipulator over a two day period on Sept 29 and 30.
Ground controllers at Johnson Space Center intricately maneuvered DEXTRE to pluck RapidScat and its nadir adapter from the unpressurized trunk section of the Dragon cargo ship and attached it to a vacant external mounting platform on the Columbus module holding mechanical and electrical connections.
The nadir adapter orients the instrument to point its antennae at Earth.
The couch sized instrument and adapter together measure about 49 x 46 x 83 inches (124 x 117 x 211 centimeters).
“The initial quality of the RapidScat wind data and the timely availability of products so soon after launch are remarkable,” said Paul Chang, ocean vector winds science team lead at NOAA’s National Environmental Satellite, Data and Information Service (NESDIS)/Center for Satellite Applications and Research (STAR), Silver Spring, Maryland.
“NOAA is looking forward to using RapidScat data to help support marine wind and wave forecasting and warning, and to exploring the unique sampling of the ocean wind fields provided by the space station’s orbit.”
This has been a banner year for NASA’s Earth science missions. At least five missions will be launched to space within a 12 month period, the most new Earth-observing mission launches in one year in more than a decade.
ISS-RapidScat is the third of five NASA Earth science missions scheduled to launch over a year.
NASA has already launched the of the Global Precipitation Measurement (GPM) Core Observatory, a joint mission with the Japan Aerospace Exploration Agency, in February and the Orbiting Carbon Observatory-2 (OCO-2) carbon observatory in July 2014.

After moving out to the launch pad earlier this week, NASA’s first Orion spacecraft was hoisted atop the most powerful rocket in the world and awaits blastoff from Cape Canaveral, Florida, in early December on a critical test flight that will pave the way for human missions to deep space for the first time in more than four decades since NASA’s Apollo moon landing missions ended in 1972.
NASA’s cool new set of infographics above and below explain 8 key events on Orion’s Exploration Flight Test-1 (EFT-1) mission and its first trip to orbit and back.
Orion will lift off on a Delta IV Heavy rocket on its inaugural test flight to space on the uncrewed EFT-1 mission at 7:05 a.m. EST on December 4, 2014, from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.
The two-orbit, four and a half hour Orion 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.
EFT-1 will test the rocket, second stage, jettison mechanisms, as well as avionics, attitude control, computers, and electronic systems inside the Orion spacecraft.
Then the spacecraft will carry out a high speed re-entry through the atmosphere at speeds approaching 20,000 mph and scorching temperatures near 4,000 degrees Fahrenheit to test the heat shield, before splashing down for a parachute assisted landing in the Pacific Ocean.
Here’s what Orion’s ocean splashdown and recovery by Navy divers will look like:
Orion is NASA’s next generation human rated vehicle that will 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 United Launch Alliance Delta IV Heavy rocket is the world’s most powerful rocket. The triple barreled Delta IV Heavy booster is the only rocket sufficiently powerful to launch the 50,000 pound Orion EFT-1 spacecraft to orbit.
The first stage of the mammoth Delta IV Heavy generates some 2 million pounds of liftoff thrust.
Watch for Ken’s Orion coverage, and he’ll be at KSC for the historic launch on Dec. 4.

After years of effort, NASA’s pathfinding Orion spacecraft was rolled out to the launch pad early this morning, Wednesday, Nov. 12, and hoisted atop the rocket that will blast it to space on its history making maiden test flight in December.
Orion’s penultimate journey began late Tuesday, when the spacecraft was moved 22 miles on a wheeled transporter from the Kennedy Space Center assembly site to the Cape Canaveral launch site at pad 37 for an eight hour ride.
Watch a timelapse of the journey, below:
Technicians then lifted the 50,000 pound spacecraft about 200 feet onto a United Launch Alliance Delta IV Heavy rocket, the world’s most powerful rocket, in preparation for its first trip to space.
Orion’s promise is that it will fly America’s astronauts back to deep space for the first time in over four decades since the NASA’s Apollo moon landing missions ended in 1972.
Liftoff of the state-of-the-art Orion spacecraft on the unmanned Exploration Flight Test-1 (EFT-1) mission is slated for December 4, 2014, from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.
“This is the next step on our journey to Mars, and it’s a big one,” said William Gerstenmaier, NASA’s associate administrator for human exploration and operations.
“In less than a month, Orion will travel farther than any spacecraft built for humans has been in more than 40 years. That’s a huge milestone for NASA, and for all of us who want to see humans go to deep space.”
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 fully assembled Orion vehicle stack consists of the crew module, service module, launch abort system, and adapter that connect it to the Delta IV Heavy rocket. It was completed in October inside Kennedy’s Launch Abort System Facility.
Today’s move was completed without issue after a one day delay due to storms in the KSC area.
The triple barreled Delta IV Heavy booster became the world’s most powerful rocket upon the retirement of NASA’s Space Shuttle program in 2011 and is the only rocket sufficiently powerful to launch the Orion EFT-1 spacecraft.
The two-orbit, four and a half hour EFT-1 flight 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.
Orion will travel almost 60,000 miles into space during the uncrewed Dec. 4 test flight.
Stay tuned here for Ken’s continuing Orion and Earth and planetary science and human spaceflight news.
And Orion is so big and heavy that she’s not launching on just any old standard rocket.
To blast the uncrewed Orion to orbit on its maiden mission requires the most powerful booster on Planet Earth – namely the United Launch Alliance Delta IV Heavy rocket.
Liftoff of the state-of-the-art Orion spacecraft on the unmanned Exploration Flight Test-1 (EFT-1) mission is slated for December 4, 2014, from Space Launch Complex 37 (SLC-37) at Cape Canaveral Air Force Station in Florida.
Just days ago, the launch team successfully completed a countdown and wet dress rehearsal fueling test on the rocket itself – minus Orion – at launch complex 37.
The high fidelity rehearsal included fully powering up the booster and loading the tanks with cryogenic fuel and oxidizer, liquid oxygen, and liquid hydrogen.
ULA technicians and engineers practiced the countdown on Nov. 5 which included fueling the core stages of the Delta IV Heavy rocket.
“Working in control rooms at Cape Canaveral Air Force Station in Florida, countdown operators followed the same steps they will take on launch day. The simulation also allowed controllers to evaluate the fuel loading and draining systems on the complex rocket before the Orion spacecraft is placed atop the launcher,” said NASA.
The next key mission milestone is attachment of the completed Orion vehicle stack on top of the rocket. Read more about the fully assembled Orion – here.
Today’s scheduled rollout of Orion to the launch pad for hoisting atop the rocket was scrubbed due to poor weather.
The triple barreled Delta IV Heavy booster became the world’s most powerful rocket upon the retirement of NASA’s Space Shuttle program in 2011 and is the only rocket sufficiently powerful to launch the Orion EFT-1 spacecraft.
The first stage of the mammoth Delta IV Heavy generates some 2 million pounds of liftoff thrust.
“The team has worked extremely hard to ensure this vehicle is processed with the utmost attention to detail and focus on mission success,” according to Tony Taliancich, ULA’s director of East Coast Launch Operations.
“The Delta IV Heavy is the world’s most powerful launch vehicle flying today, and we are excited to be supporting our customer for this critical flight test to collect data and reduce overall mission risks and costs for the program.”
From now until launch technicians will continue to conduct the final processing, testing, and checkout of the Delta IV Heavy booster.
The Delta IV Heavy first stage is comprised of a trio of three Common Booster Cores (CBCs).
Each CBC measures 134 feet in length and 17 feet in diameter. They are equipped with an RS-68 engine powered by liquid hydrogen and liquid oxygen propellants producing 656,000 pounds of thrust. Together they generate 1.96 million pounds of thrust.
The first CBC booster was attached to the center booster in June. The second one was attached in early August.
This fall I visited the ULA’s Horizontal Integration Facility (HIF) during a media tour after the three CBCs had been joined together as well as earlier this year after the first two CBCs arrived by barge from their ULA assembly plant in Decatur, Alabama, located about 20 miles west of Huntsville.

“This mission is a stepping stone on NASA’s journey to Mars,” said NASA Associate Administrator Robert Lightfoot.
.
“The EFT-1 mission is so important to NASA. We will test the capsule with a reentry velocity of about 85% of what’s expected by [astronauts] returning from Mars.”
“We will test the heat shield, the separation of the fairing, and exercise over 50% of the eventual software and electronic systems inside the Orion spacecraft. We will also test the recovery systems coming back into the Pacific Ocean.”

Technicians at the Kennedy Space Center have put the finishing touches on NASA’s first Orion crew module, marking the conclusion of NASA’s multi-year-long effort to build and prepare the vehicle for its maiden launch in December and take the first steps towards sending humans back to deep space in four decades since Apollo.
The Orion spacecraft is all set to be rolled out from Kennedy’s Launch Abort System Facility to Launch Complex 37 at Cape Canaveral Air Force Station on Monday evening, Nov 10.
Orion is slated to liftoff on its first unmanned orbital test flight, dubbed Exploration Flight Test-1 (EFT-1), on Dec. 4.
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 fully assembled Orion vehicle stack consists of the crew module, service module, launch abort system and adapter, residing on a transporter in Kennedy’s Launch Abort System Facility.
“This is just the first of what will be a long line of exploration missions beyond low earth orbit, and in a few years we will be sending our astronauts to destinations humans have never experienced,” said Bill Hill, deputy associate administrator for Exploration Systems Development, in a statement.
“It’s thrilling to be a part of the journey now, at the beginning.”
After arriving at pad 37, the Orion stack will be hoisted and installed atop the United Launch Alliance Delta IV Heavy rocket that will carry it into space for its uncrewed EFT-1 maiden flight test.
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.

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.
“NASA is pushing the boundaries of exploration and working hard to send people to Mars in the future,” said Mark Geyer, Orion Program manager, in a NASA statement.
“When we set foot on the Red Planet, we’ll be exploring for all of humanity.”
Watch for Ken’s Orion coverage and he’ll be at at KSC for the launch on Dec. 4.

In the wake of last weeks disastrous failure of the Orbital Sciences commercial Antares rocket seconds after blastoff from NASA’s Wallops Flight Facility, VA, on a critical resupply mission to the space station, Orbital’s Chairman announced a comprehensive way forward involving a two pronged strategy to quickly fulfill their cargo commitments to NASA as well as upgrade the rockets’ first stage propulsion system.
“Orbital announced comprehensive plans to fulfill its contract commitments under NASA’s Commercial Resupply Services (CRS) program as well as to accelerate an upgrade of the Antares medium-class launcher’s main propulsion system, the company said in a statement and discussion by David Thompson, Orbital’s Chairman and Chief Executive Officer, during an investors conference call.
“Orbital is taking decisive action to fulfill our commitments to NASA in support of safe and productive operations of the Space Station,” said Thompson.
“While last week’s Antares failure was very disappointing to all of us, the company is already implementing a contingency plan to overcome this setback. We intend to move forward safely but also expeditiously to put our CRS cargo program back on track and to accelerate the introduction of our upgraded Antares rocket.”
The Orbital Sciences privately developed Antares rocket was doomed by a sudden mid-air explosion some 15 seconds after liftoff from NASA’s Wallops Flight Facility, VA, at 6:22 p.m. EDT on Tuesday, October 28.
A turbopump failure in one of the rockets two Aerojet Rocketdyne AJ26 engines that power the first stage has been identified by Orbital’s Accident Investigation Board (AIB) as the probable cause of the huge explosion that destroyed the booster and its NASA payload in a raging fireball after liftoff.
The AJ26 engines were originally manufactured some 40 years ago in the then Soviet Union as the NK-33. They were refurbished and “Americanized” by Aerojet Rocketdyne.
“While still preliminary and subject to change, current evidence strongly suggests that one of the two AJ26 main engines that powered Antares first stage failed about 15 seconds after ignition. At this time, we believe the failure likely originated in or directly affected the turbopump machinery of this engine, but I want to stress that more analysis will be required to confirm that this finding is correct,” said Thompson.
Overall this was the 5th Antares launch using the AJ26 engines.
AJ26 engine failure was immediately suspected, though by no means certain, based on an inspection of numerous photos and videos from myself and many others that clearly showed a violent explosion emanating from the base of the two stage rocket.
The remainder of the first stage and Antares entire upper stage was clearly intact at the moment of the explosion in all the imagery.
Thompson said Orbital is accelerating contingency planning and is looking at several alternate rocket suppliers in the US and Europe to launch Orbital’s Cygnus cargo freighter to the station.
Cygnus has functioned perfectly to date and was designed to launch on other vehicles.
“Orbital will employ the inherent flexibility of our Cygnus cargo spacecraft that permits it to be launched on third party launch vehicles and to accommodate heavier cargo loads as allowed by more capable launchers. This option had already been contemplated in previous contingency plans and product improvement roadmaps and its implementation should be relatively straightforward.”
Thompson furthermore stated that the company would need to launch one or two Cygnus spacecraft on alternate providers and hope to do so during 2015 so as to keep their CRS resupply commitments to NASA on track and with minimal delay.
The next Antares/Cygnus launch from Wallops had been scheduled for no earlier than April 2015.
The April launch had been scheduled to introduce the enhanced, longer Cygnus with the capability to carry a significantly heavier cargo load to the ISS.
By employing the enhanced Cygnus, Orbital hopes to fulfill its entire CRS contract cargo up mass commitment to NASA in four flights instead of five by the end of 2016.
“Taking advantage of the spacecraft’s flexibility, we will purchase one or two non-Antares launch vehicles for Cygnus flights in 2015 and possibly in early 2016 and combine them with several upgraded Antares rocket launches of additional Cygnus spacecraft in 2016 to deliver all remaining CRS cargo,” said Thompson.
“By consolidating the cargo of five previously-planned CRS missions into four more capable ones, we believe we can maintain a similar or perhaps even a somewhat better delivery schedule than we were on before last week’s launch failure, completing all current CRS program cargo deliveries by the end of 2016.”
The possible launch providers include a United Launch Alliance Atlas V, a SpaceX Falcon 9 or a rocket from the European Space Agency at the Guiana Space Center.
Orbital had previously announced and managers told Universe Today that the company already had decided on plans to integrate a new first stage engine in a new and upgraded second generation version of Antares.
But no one at Orbital will confirm the identity of the chosen first stage engines.
“We will accelerate the introduction of Antares’ upgraded propulsion system, advancing its initial launch date from the previously planned 2017 into 2016,” said Thompson.
Thompson also said the AJ26 engine are unlikely to be used again without complete assurances.
“Consequently, we will likely discontinue the use of the AJ26 rocket engines that had been used on the first five Antares vehicles unless and until those engines can be conclusively shown to be flight worthy,” Thompson stated.
See my exclusive photos herein showing the AJ26 engines with their original NK-33 stencil, during prelaunch processing and mating to the first stage inside Orbital’s Horizontal Integration Facility (HIF) at NASA Wallops.
The NK-33 was originally designed and manufactured in the 1960s by the Kuznetsov Design Bureau for the Soviet Union’s planned N1 rocket to propel cosmonauts to the moon during the space race with NASA’s hugely successful Apollo Moon Landing program.
The 14 story Antares rocket is a two stage vehicle.
The liquid fueled first stage is filled with about 550,000 pounds (250,000 kg) of Liquid Oxygen and Refined Petroleum (LOX/RP) and powered by a pair of AJ26 engines that generate a combined 734,000 pounds (3,265kN) of sea level thrust.
The Oct. 28 launch disaster was just the latest in a string of serious problems with the AJ-26/NK-33 engines.
Earlier this year an AJ26 engine failed and exploded during pre launch acceptance testing on a test stand on May 22, 2014 at NASA’s Stennis Space Center in Mississippi.
Besides completely destroying the AJ26 engine, the explosion during engine testing also severely damaged the Stennis test stand. It has taken months of hard work to rebuild and restore the test stand and place it back into service.
The doomed mission was bound for the International Space Station (ISS) on a flight to bring up some 5000 pounds of (2200 kg) of science experiments, research instruments, crew provisions, spare parts, spacewalk and computer equipment and gear on a critical resupply mission in the Cygnus resupply ship bound for the International Space Station (ISS).
The Orbital-3, or Orb-3, mission was to be 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 flights.
I was an eyewitness to the awful devastation suffered by the Orb-3 mission from the press viewing site at NASA Wallops located at a distance of about 1.8 miles away from the launch complex.
I was interviewed by NBC News and you can watch the entire story and see my Antares explosion photos featured at NBC Nightly News on Oct. 29 here.

NASA WALLOPS FLIGHT FACILITY, VA – Investigators probing last week’s catastrophic failure of an Antares commercial rocket moments after liftoff, are pointing the finger at the rocket’s Soviet-era built engines as the probable cause of the huge explosion that destroyed the booster and its NASA payload in a raging fireball after liftoff from NASA’s Wallops Flight Facility, VA, according to Orbital Sciences managers.
The Orbital Sciences privately developed Antares rocket was doomed by a sudden mid-air explosion some 15 seconds after liftoff from NASA’s Wallops Flight Facility, VA, at 6:22 p.m. EDT on Tuesday, October 28.
Antares’ first stage is powered by a pair of refurbished Aerojet Rocketdyne AJ26 engines originally manufactured some 40 years ago in the then Soviet Union and originally designated as the NK-33. Overall this was the 5th Antares launch using the AJ26 engines.
See my exclusive photos above and below showing the AJ26 engines with their original NK-33 stencil, during prelaunch processing and mating to the first stage inside Orbital’s Horizontal Integration Facility (HIF) at NASA Wallops.
The NK-33 was originally designed and manufactured in the 1960s by the Kuznetsov Design Bureau for the Soviet Union’s planned N1 rocket to propel cosmonauts to the moon during the space race with NASA’s hugely successful Apollo Moon Landing program.
Rocket developer Orbital Sciences Corp. said today, Nov. 5, that the launch mishap was probably due to “a failure in one of the two Aerojet Rocketdyne AJ26 stage one main engines.”
Engineers assisting Orbital’s Accident Investigation Board (AIB) say that failure in the AJ26 turbopump is the likely cause. The AIB is chaired by David Steffy, Chief Engineer of Orbital’s Advanced Programs Group.
“While the work of the AIB continues, preliminary evidence and analysis conducted to date points to a probable turbopump-related failure in one of the two Aerojet Rocketdyne AJ26 stage one main engines,” Orbital said in a statement.
“As a result, the use of these engines for the Antares vehicle likely will be discontinued,” said Orbital.
“We will likely discontinue the use of AJ26 rocket engines that had been used on the first five Antares launch vehicles unless and until those engines can be conclusively shown to be flight worthy,” noted David Thompson, Orbital’s Chairman and Chief Executive Officer, during an investor conference call.
Orbital’s options for the way forward will be outlined in a separate story.

Earlier this year an AJ26 engine failed and exploded during pre launch acceptance testing on a test stand on May 22, 2014, at NASA’s Stennis Space Center in Mississippi.
Besides completely destroying the AJ26 engine, the explosion during engine testing also severely damaged the Stennis test stand. It has taken months of hard work to rebuild and restore the test stand and place it back into service.
An extensive engine analysis, recheck and test stand firings by Aerojet Rocketdyne and Orbital Sciences engineers was conducted to clear this new pair of engines for flight.
Aerojet Rocketdyne purchased approximately 40 NK-33 engines in the mid-1990s and ‘Americanized’ them with multiple modifications including a gimbal steering mechanism.
AJ26 engine failure was immediately suspected, though by no means certain, based on an inspection of numerous photos and videos from myself and many others that clearly showed a violent explosion emanating from the base of the two stage rocket.
The remainder of the first stage and Antares entire upper stage was clearly intact at the moment of the explosion in all the imagery.
Antares was carrying the unmanned Cygnus cargo freighter on a mission dubbed Orb-3 to resupply the six person crew living aboard the International Space Station (ISS) with science experiments and needed equipment.
The AIB is making rapid progress in assessing the accident’s cause based on an analysis of the rocket’s telemetry as well as the substantial amounts of debris collected from the rocket and the Cygnus cargo freighter at the Wallops launch site.
A preliminary review of telemetry and video data has been conducted and substantial debris from the Antares rocket and its Cygnus payload has been collected and examined.
The 14 story Antares rocket is a two stage vehicle.
The liquid fueled first stage is filled with about 550,000 pounds (250,000 kg) of Liquid Oxygen and Refined Petroleum (LOX/RP) and powered by a pair of AJ26 engines that generate a combined 734,000 pounds (3,265kN) of sea level thrust.
The doomed mission was bound for the International Space Station (ISS) on a flight to bring up some 5000 pounds of (2200 kg) of science experiments, research instruments, crew provisions, spare parts, spacewalk and computer equipment and gear on a critical resupply mission in the Cygnus resupply ship.
The Orbital-3, or Orb-3, mission was to be 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 flights.
I was an eyewitness to the awful devastation suffered by the Orb-3 mission from the press viewing site at NASA Wallops located at a distance of about 1.8 miles away from the launch complex.
I was interviewed by NBC News and you can watch the entire story and see my Antares explosion photos featured at NBC Nightly News on Oct. 29 here.

NASA WALLOPS FLIGHT FACILITY, VA – Investigators probing the Antares launch disaster are focusing on clues pointing to a failure in the first stage propulsion system that resulted in a loss of thrust and explosive mid-air destruction of the commercial rocket moments after liftoff from NASA’s Wallops Flight Facility, VA, at 6:22 p.m. EDT on Tuesday, October 28.
The highly anticipated first night launch of the Orbital Sciences Corp. privately developed Antares rocket blasted off nominally and ascended for about 15 seconds until a rapid fire series of sudden and totally unexpected loud explosions sent shock waves reverberating all around the launch site and surroundings for miles and the rocket was quickly consumed in a raging fireball.
Antares was carrying the unmanned Cygnus cargo freighter on a mission dubbed Orb-3 to resupply the six person crew living aboard the International Space Station (ISS) with science experiments and needed equipment.
The 14 story Antares rocket is a two stage vehicle. The liquid fueled first stage is filled with about 550,000 pounds (250,000 kg) of Liquid Oxygen and Refined Petroleum (LOX/RP) and powered by a pair of AJ26 engines originally manufactured some 40 years ago in the then Soviet Union and designated as the NK-33.
Earlier this year an AJ26 engine failed and exploded during acceptance testing on May 22, 2014, at NASA’s Stennis Space Center in Mississippi. An extensive analysis and recheck by Orbital Sciences was conducted to clear this pair for flight.
I was an eyewitness to the awful devastation suffered by the Orb-3 mission from the press viewing site at NASA Wallops located at a distance of about 1.8 miles away from the launch complex.
Numerous photos and videos from myself (see herein) and many others clearly show a violent explosion emanating from the base of the two stage rocket. The remainder of the first stage and the entire upper stage was clearly intact at that point.
NASA announced that Orbital Sciences is leading the investigation into the rocket failure and quickly appointed an Accident Investigation Board (AIB) chaired by David Steffy, Chief Engineer of Orbital’s Advanced Programs Group.
The AIB is working under the oversight of the Federal Aviation Administration (FAA).
“Evidence suggests the failure initiated in the first stage after which the vehicle lost its propulsive capability and fell back to the ground impacting near, but not on, the launch pad,” Orbital said in a statement.
At the post launch disaster briefing at NASA Wallops, I asked Frank Culbertson, Orbital’s Executive Vice President and General Manager of its Advanced Programs Group, to provide any specifics of the sequence of events and failure, a timeline of events, and whether the engines failed.
“The ascent stopped, there was disassembly of the first stage, and then it fell to Earth. The way the accident investigation proceeds is we lock down all the data [after the accident]. Then we go through a very methodical process to recreate the data and evaluate it. We need time to look at what failed from both a video and telemetry standpoint,” Culbertson told Universe Today.
The rocket telemetry has now been released to the accident investigation board.
“Our engineers presented a very quick look assessment to the Accident Investigation Board at the end of the day. It appears the Antares vehicle had a nominal pre-launch and launch sequence with no issues noted,” Orbital said in a statement.
“All systems appeared to be performing nominally until approximately T+15 seconds at which point the failure occurred.”
Blastoff of the 14 story Antares rocket took place from the beachside Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops situated on the eastern shore of Virginia.
After the failure occurred the rocket fell back to the ground near, but not on top of, the launch pad.
“Prior to impacting the ground, the rocket’s Flight Termination System was engaged by the designated official in the Wallops Range Control Center,” said Orbital.
Since the rocket impacted just north of the pad, that damage was not as bad as initially feared.
From a public viewing area about two miles away, I captured some side views of the pad complex and damage it sustained.
Check out the details of my assessment in my prior article and exclusive photos showing some clearly discernible damage to the Antares rocket launch pad – here.

Among the top tasks of the AIB are “developing a ‘fault tree’ and a timeline of the important events during the launch sequence,” using the large volume of data available.
“We will analyze the telemetry. We have reams of data and telemetry that come down during launch and we will be analyzing that carefully to see if we can determine exactly the sequence of events, what went wrong, and then what we can do to fix it,” said Culbertson.
The accident team is also gathering and evaluating launch site debris.
“Over the weekend, Orbital’s Wallops-based Antares personnel continued to identify, catalogue, secure, and geolocate debris found at the launch site in order to preserve physical evidence and provide a record of the launch site following the mishap that will be useful for the AIB’s analysis and determination of what caused the Antares launch failure,” said Orbital.
Culberston expressed Orbital’s regret for the launch failure.
“We are disappointed we could not fulfill our obligation to the International Space Station program and deliver this load of cargo. And especially to the researchers who had science on board as well as to the people who had hardware and components on board for going to the station.”
“It’s a tough time to lose a launch vehicle and payload like this. Our team worked very hard to prepare it, with a lot of testing and analysis to get ready for this mission.”
Culbertson emphasized that Orbital will fix the problem and move forward.
“Something went wrong and we will find out what that is. We will determine the root cause and we will correct that. And we will come back and fly here at Wallops again. We will do all the things that are necessary to make sure it is as safe as we can make it, and that we solve the immediate problem of this particular mission.”
Culbertson noted that the public should not touch any rocket debris found.
“The investigation will include evaluating the debris around the launch pad. The rocket had a lot of hazardous equipment and materials on board that people should not be looking for or wanting to collect souvenirs. If you find anything that washes ashore or landed you should call the local authorities and definitely not touch it.”

At this point the future is unclear.
