NASA and SpaceX are now targeting Dec. 19 as the launch date for the next unmanned cargo run to the International Space Station (ISS) under NASA’s Commercial Resupply Services contract.
The fifth SpaceX cargo mission was postponed from Dec. 16 to Dec. 19 to “allow SpaceX to take extra time to ensure they do everything possible on the ground to prepare for a successful launch,” according to a statement from NASA.
The Dragon spacecraft will launch atop a SpaceX Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
Both the Falcon 9 rocket and its Dragon spacecraft are in good health, according to NASA.
The mission dubbed SpaceX CRS-5 is slated for liftoff at 1:20 p.m.
An on time liftoff will result in a rendezvous with the ISS on Sunday. The crew would grapple the Dragon with the stations 57 foot long robotic arm at about 6 a.m.

US astronaut and station commander Barry Wilmore will operate the Canadarm2 to capture the SpaceX Dragon when it arrives Sunday morning. ESA astronaut Samantha Cristoforetti will assist Wilmore working at a robotics workstation inside the domed Cupola module during the commercial craft’s approach and rendezvous.
The unmanned cargo freighter is loaded with more than 3,700 pounds of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear.
The Dragon research experiments will support over 256 science and research investigations for the six person space station crews on Expeditions 42 and 43.
Among the payloads is the Cloud-Aerosol Transport System (CATS), a remote-sensing laser instrument to measure clouds and the location and distribution of pollution, dust, smoke, and other particulates and aerosols in the atmosphere.
A secondary objective of SpaceX is to attempt to recover the Falcon 9 first stage on an off shore barge.
The SpaceX CRS-4 mission to the ISS concluded with a successful splashdown on Oct 25 after a month long stay.
The SpaceX CRS-5 launch is the first cargo launch to the ISS since the doomed Orbital Sciences Antares/Cygnus launch ended in catastrophe on Oct. 28.
With Antares launches on indefinite hold, the US supply train to the ISS is now wholly dependent on SpaceX.
Orbital Sciences has now contracted United Launch Alliance (ULA) to launch the firms Cygnus cargo freighter to the ISS by late 2015 on an Atlas V rocket.

Following the catastrophic Oct. 28 failure of an Orbital Sciences Corporation Antares rocket on a critical resupply mission to the space station for NASA, the company is seeking to quickly make up the loss to NASA by announcing the selection of the venerable Atlas V rocket built by United Launch Alliance to launch Orbital’s next Cygnus cargo ship to the orbital science lab.
Orbital and ULA signed a contract to launch at least one, and up to two, Cygnus cargo missions to the International Space Station (ISS) under NASA’s Commercial Resupply Services (CRS) program.
The first Cygnus mission would liftoff sometime late in the fourth quarter of 2015 aboard an Atlas V 401 vehicle from Space Launch Complex 41 (SLC-41) at Cape Canaveral Air Force Station in Florida.
Given that ULA’s full launch manifest was fairly full for the next 18 months, Orbital is fortunate to have arranged one or two available launch slots so quickly in the wake of the Antares launch disaster.
“Orbital is pleased to partner with ULA for these important cargo missions to the International Space Station,” said Frank Culbertson, Orbital executive vice president and general manager of its Advanced Programs Group.
“ULA’s ability to integrate and launch missions on relatively short notice demonstrates ULA’s manifest flexibility and responsiveness to customer launch needs.”

Orbital also stated that there will be “no cost increase to the space agency” by utilizing the Atlas V as an interim launcher.
If necessary, a second Cygnus would be launched by the Atlas V in 2016.
The 401 version of the Atlas uses a 4 meter diameter payload fairing, no solid rocket boosters strapped on to the first stage, and a single-engine Centaur upper stage.

Orbital had been evaluating at least three different potential launch providers.
Observers speculated that in addition to ULA, the other possibilities included a SpaceX Falcon 9 or a rocket from the European Space Agency at the Guiana Space Center.
“We could not be more honored that Orbital selected ULA to launch its Cygnus spacecraft,” said Jim Sponnick, vice president, Atlas and Delta Programs.
“This mission was awarded in a highly competitive environment, and we look forward to continuing ULA’s long history of providing reliable, cost-effective launch services for customers.”
The Orbital-3, or Orb-3, mission that ended in disaster on Oct. 28 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.
The highly anticipated launch of the Antares rocket on Oct 28 suddenly went awry when one of the Soviet-era first stage engines unexpectedly exploded and cascaded into a spectacular aerial fireball just above the launch pad at NASA’s Wallops Flight Facility on the Orb-3 mission to the ISS.

Orbital was awarded a $1.9 Billion contract with NASA under the CRS program to deliver 20,000 kilograms of research experiments, crew provisions, spare parts, and hardware for the eight ISS flights.
In choosing the Atlas V with a greater lift capacity compared to Antares, Orbital will also be able to significantly increase the cargo mass loaded inside the Cygnus by about 35%.
This may allow Orbital to meet its overall space station payload obligation to NASA in 7 total flights vs. the originally planned 8.
The venerable Atlas V rocket is one of the most reliable and well built rockets in the world.
The next Orbital Sciences Cygnus cargo ship to the space station will launch inside a 4m diameter payload firing, as shown here, on a United Launch Alliance Altas V 401 rocket used for NASA’s MAVEN.

Indeed the Atlas V has been entrusted to launch many high value missions for NASA and the Defense Department – such as MAVEN, Curiosity, JUNO, TDRSS, and the X-37 B.
MAVEN launched on a similar 401 configuration being planned for Cygnus.
The two-stage Atlas rocket is also being man-rated right now to launch humans to low Earth orbit in the near future.
Orbital is still in the process of deciding on a new first stage propulsion system for Antares’ return to flight planned for perhaps sometime in 2016.

Story and images expanded
NASA WALLOPS FLIGHT FACILITY, VA – Moments after a seemingly glorious liftoff on Oct. 28, 2014, the Orbital Sciences Corp. commercial Antares rocket suffered a catastrophic failure as one of the Soviet-era first stage engines exploded and cascaded into a spectacular aerial fireball just above the launch pad at NASA’s Wallops Flight Facility on the doomed Orb-3 mission to the International Space Station (ISS).
Although I witnessed and photographed the launch failure from the media viewing area on site at NASA Wallops from a distance of about 1.8 miles away, myself and a small group of space journalists working together from Universe Today, AmericaSpace, and Zero-G News had also placed sound activated cameras directly at the launch pad to capture the most spectacular up close views for what we all expected to be a “nominal” launch. Our imagery had been impounded by accident investigators – until being released to us now.
Now in part 2 of this exclusive series of video and photos our team can show you the terrible fate suffered by Antares after its destructive descent and frightening incineration as it was consumed by a hellish inferno.
My time lapse video above clearly shows the explosion and incendiary descent of Antares into a mammoth fireball.
As I reported in Part 1, all of our team’s cameras and image cards were impounded for nearly a month by Orbital’s official and independent Accident Investigation Board (AIB) that was assembled quickly in the aftermath of the Antares launch failure disaster and charged with determining the root cause of the launch failure.
The videos and photos captured on our image cards were used as evidence and scrutinized by the investigators searching for clues as to the cause and have only just been returned to us in the past few days.
One image clearly shows that the south side engine nozzle of the AJ26 first stage engine was intact and had shut down after the initial explosion and during the plummet. Therefore it was the north side engine that blew up and led to the launch failure. See my up close AJ26 engine photo below.

Similar launch pad photos taken by NASA and Orbital Sciences cameras have not been publicly released and may not be released for some time to come.
The videos and images collected here are the work of my colleagues Matthew Travis, Elliot Severn, Alex Polimeni, Charles Twine, Jeff Seibert, Mike Barrett, and myself, and show exquisite, heretofore unreleased, views of the explosion, fireball, and wreckage from various positions all around the launch pad.
Our remote cameras were placed all around the Antares pad OA at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, VA, and somehow miraculously survived the rocket’s destruction as it plunged to the ground very near and just north of the seaside launch pad.
A turbopump failure in one of the rocket’s Soviet-era first stage engines has been identified as the most likely cause of the Antares’ destruction according to official statements from David Thompson, Orbital’s Chairman and Chief Executive Officer.
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.
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.
The astronauts and cosmonauts depend on a regular supply train from the ISS partners to kept it afloat and productive on a 24/7 basis.
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.

NASA WALLOPS FLIGHT FACILITY, VA – All was calm, the air was crisp with hope, and the skies were clear as far as the eye could see as the clock ticked down to T MINUS Zero for the Oct. 28, 2014, blastoff of an Orbital Sciences commercial Antares rocket from NASA’s Wallops Flight Facility, VA, on a mission of critical importance bound for the International Space Station and stocked with science and life support supplies for the six humans living and working aboard.
Tragically it was not to be – as I reported live from the NASA Wallops press site on that fateful October day. The 133 foot tall rocket’s base exploded violently and unexpectedly just seconds after a beautiful evening liftoff due to the failure of one of the refurbished AJ26 first stage “Americanized” Soviet-era engines built four decades ago.
And now for the first time, I can show you precisely what the terrible incendiary view was like through exclusive, up close launch pad photos and videos from myself and a group of space journalists working together from Universe Today, AmericaSpace, and Zero-G news.

I was an eyewitness to the awful devastation suffered by the Antares/Cygnus 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.
Our remote cameras were placed directly adjacent to the Antares pad OA at the Mid-Atlantic Regional Spaceport (MARS) on Wallops Island, VA, and miraculously survived the rocket’s destruction as it plunged to the ground very near and just north of the seaside launch pad.

Moments after liftoff, the highly anticipated Antares launch suddenly devolved into utter catastrophe and a doomed descent into a hellish inferno of bloodcurdling terror – falling as a flaming incinerating carcass of unspeakable horror that ended in a mammoth deafening explosion as the pitiful wreckage smashed into the ground and blew back upwards as a raging fireball and hurtling debris that was visible across a wide swath of the sky.
The awful scene was seen by hordes of expectant spectators for miles around the Wallops area.
The disaster’s cause has almost certainly been traced to a turbopump failure in one of the rocket’s Soviet-era first stage engines, according to official statements from David Thompson, Orbital’s Chairman and Chief Executive Officer.
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.
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.
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.
The astronauts and cosmonauts depend on a regular supply train from the ISS partners to kept it afloat and productive on a 24/7 basis.
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.

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.

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.

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.
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.

NASA WALLOPS FLIGHT FACILITY, VA – Barely a day ago I witnessed the sudden and utter destruction of an Orbital Sciences Antares rocket being consumed in a totally unexpected devastating fireball moments after blastoff from NASA’s Wallops Flight Facility on the eastern shore of Virginia at 6:22 p.m. EDT on Tuesday, October 28.
See above my raw video footage of the catastrophic Orb-3 launch taken from the media viewing site at NASA Wallops located about 1.8 miles away from the beachside Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at Wallops.
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.
The highly anticipated 1st night launch of Antares would have been visible to tens of millions up and down the eastern seaboard from South Carolina to Maine. Overall it was the 5th Antares launch.
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 the critical resupply mission dubbed Orb-3 bound for the International Space Station (ISS).
Listen closely as the sound gradually builds with Antares slowly lifting off from the pad to a deafening crescendo as it explodes violently and without warning followed by multiple blasts and detonations as the rockets breaks apart in a hail of dangerous debris.
You can clearly here the shocked voices of spectators disbelief, including my own, at was has just transpired.
Then you’ll see the see the ‘shock and awe’ as the sky lights on fire with the rockets catastrophic destruction and the camera shakes as the blasts shock wave zooms past us at the media site followed by a quick blast of noticeable heat.
Rapidly thereafter our NASA escorts ordered an immediate evacuation to protect everyone lives. There were no injuries.

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.
A steady train of science experiments and supplies are required to continue operating the massive orbiting outpost and its six person crew.

Orbital 3 Launch from NASA Wallops Island, VA on Oct. 27, 2014- Time of First Sighting Map. 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).

NASA WALLOPS FLIGHT FACILITY, VA – Tens of millions of US East Coast residents can expect a dinnertime spectacular for the first ever nighttime launch of the commercial Orbital Sciences Corp. Antares rocket slated to blastoff on Monday evening, October 27, from a beachside NASA launch base along the eastern shore of Virginia – if the weather holds as currently forecast.
You can watch live, below.
Antares is carrying Orbital’s private Cygnus cargo freighter loaded with a diverse array of science experiments on a critical cargo resupply mission named Orb-3, and is bound for the International Space Station (ISS).
NASA and Orbital Sciences are now targeting liftoff at 6:45 p.m. EDT on Oct. 27 from Launch Pad 0A at the Mid-Atlantic Regional Spaceport (MARS) at NASA Wallops Island Flight Facility on Virginia’s shore.

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.

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.

Hurricane Gonzalo, the first major Atlantic Ocean basin hurricane in three years, has strengthened to a dangerous Category 4 storm, threatening Bermuda and forcing a postponement of the upcoming launch of the Orbital Sciences Antares rocket to the space station from the Virginia shore to no earlier than Oct. 27.
A hurricane warning is in effect for the entire island of Bermuda.
NASA and Orbital Sciences had no choice but to delay the Antares blastoff from Oct. 24 to no earlier than Oct. 27 because Bermuda is home to an “essential tracking site” that must be operational to ensure public safety in case of a launch emergency situation.
Antares had been slated for an early evening liftoff with the Cygnus cargo carrier on the Orb-3 mission to the International Space Station (ISS).
NASA and Orbital issued the following statement:
“Due to the impending arrival of Hurricane Gonzalo on the island of Bermuda, where an essential tracking site used to ensure public safety during Antares launches is located, the previously announced “no earlier than” (NET) launch date of October 24 for the Orb-3 CRS mission to the International Space Station for NASA is no longer feasible.”

The powerful Gonzalo is currently expected to make a direct hit on Bermuda on Friday afternoon, Oct. 17. It’s packing devastating maximum sustained winds exceeding 145 mph (225 kph).
NASA and NOAA satellites including the Terra, Aqua and GOES-East satellites are providing continuous coverage of Hurricane Gonzalo as it moves toward Bermuda, according to a NASA update today.
The ISS-RapidScat payload tracking ocean winds, that was just attached to the exterior of the ISS, is also designed to help with hurricane monitoring and forecasting.
Tropical storm force winds and 20 to 30 foot wave heights are expected to impact Bermuda throughout Friday and continue through Saturday and into Sunday.
“The National Hurricane Center expects hurricane-force winds, and rainfall totals of 3 to 6 inches in Bermuda. A storm surge with coastal flooding can be expected in Bermuda, with large and destructive waves along the coast. In addition, life-threatening surf and riptide conditions are likely in the Virgin Islands, Puerto Rico, Dominican Republic, Bahamas. Those dangerous conditions are expected along the U.S. East Coast and Bermuda today, Oct. 16,” according to NASA.
