Aerojet Rocketdyne, which supplies critical rocket engines powering ULA’s fleet of Atlas and Delta rockets, recently made an unsolicited offer to buy ULA for approximately $2 Billion in cash, as Universe Today reported last week.
The Vulcan is planned to replace all of ULA’s existing rockets – which are significantly more costly than those from rival launch provider SpaceX, founded by billionaire entrepreneur Elon Musk.
Boeing never “seriously entertained” the Aerojet-Rocketdyne buyout offer, Universe Today confirmed with Boeing spokesperson Cindy Anderson.
Meanwhile in stark contrast to Boeing, Lockheed Martin has “no comment” regarding the Aerojet-Rocketdyne offer to buy ULA, Universe Today confirmed with Lockheed Martin Director External Communications Matt Kramer.
Furthermore Lockheed Martin is not only noncommittal about the future of ULA but is also “currently assessing our options” concerning the development of ULA’s Vulcan rocket, Kramer told me.
“With regard to reports of an unsolicited proposal for ULA, it is not something we seriously entertained for a number of reasons,” Boeing spokesperson Anderson told Universe Today.
“Regarding Aerojet and ULA, as a matter of policy Lockheed Martin does not have a comment,” Lockheed Martin spokesman Kramer told Universe Today.

ULA was formed in 2006 as a 50:50 joint venture between Lockheed Martin and Boeing that combined their existing expendable rocket fleet families – the Atlas V and Delta IV – under one roof.
Who owns ULA is indeed of significance to all Americans – although most have never head of the company – because ULA holds a virtual monopoly on launches of vital US government national security payloads and the nation’s most critical super secret spy satellites that safeguard our national defense 24/7. ULA’s rocket fleet also launched scores of NASA’s most valuable science satellites including the Curiosity Mars rover, Dawn and New Horizons Pluto planetary probe.
Since 2006 ULA has enjoyed phenomenal launch success with its venerable fleet of Atlas V and Delta IV rockets.
“ULA is a huge part of our strategic portfolio going forward along with our satellites and manned space business. This bid we’ve really not spent much time on it at all because we’re focusing on a totally different direction,” said Chris Chadwick, president and chief executive of Boeing Defense, Space & Security, on Sept. 16 at the Air Force Association’s annual technology expo in National Harbor, Maryland – according to a report by Space News.
Boeing offered strong support for ULA and the Vulcan rocket.
Vulcan is ULA’s next generation rocket to space that can propel payloads to low Earth orbit as well as throughout the solar system – including Pluto. It is slated for an inaugural liftoff in 2019.
Vulcan’s continued development is being funded by Lockheed Martin and Boeing, but only on a quarterly basis.
The key selling point of Vulcan is that it will be an all American built rocket and it will dramatically reduce launch costs to compete toe to toe with the SpaceX Falcon rocket family.
And there is a heated competition on which of two companies will provide the new American built first stage engine that will replace the Russian-built RD-180 that currently powers the ULA Atlas V.
Vulcan’s first stage will most likely be powered by the BE-4 engine being developed by the secretive Blue Origin aerospace firm owned by billionaire Jeff Bezos.
This week ULA announced an expanded research agreement with Blue Origin about using the BE-4.
But ULA is also evaluating the AR-1 liquid fueled engine being developed by Aerojet-Rocketdyne – the company that wants to buy ULA.
The Atlas V dependence on Russia’s RD-180’s landed at the center of controversy after Russia invaded Crimea in the spring of 2014, raising the ire of Congress and enactment of a ban on their use several years in the future.
ULA is expected to make a final decision on which first stage engine to use between Blue Origin and Aerojet-Rocketdyne, sometime in 2016.
The engine choice would clearly be impacted if Aerojet-Rocketdyne buys ULA.
Boeing for its part says they strongly support ULA and continued development of the Vulcan.
“Boeing is committed to ULA and its business, and to continued leadership in all aspects of space, as evidenced by the recent announcement of an agreement with Blue Origin,” Boeing spokesperson Anderson told me.
Lockheed Martin in complete contrast did not express any long term commitment to Vulcan and just remarked they were merely “actively evaluating continued investment,” as is their right as a stakeholder.
“We have made no long-term commitments on the funding of a new rocket, and are currently assessing our options. The board is actively evaluating continued investment in the new rocket program and will continue to do so,” Lockheed Director, External Communications Matt Kramer told Universe Today.
Another factor is that Aerojet-Rocketdyne has also sought to buy the rights to manufacture the Atlas V from ULA, which is currently planned to be retired several years after Vulcan is introduced, officials have told me.

The Atlas V enjoys unparalleled success. Earlier this month on Sept. 2, ULA conducted its 99th launch with the successful blastoff of an Atlas V with the MUOS-4 military communications satellite from Cape Canaveral Air Force Station for the U.S. Navy.
Starliner will eventually blastoff atop Vulcan after the Atlas V is retired in the next decade.
Lockheed provided me this update on Vulcan and ULA on Sept 21:
“Lockheed Martin is proud of ULA’s unparalleled track record of mission success, with 99 consecutive successful launches to date. We support the important role ULA plays in providing the nation with assured access to space. ULA’s Vulcan rocket takes the best performance elements of Atlas and Delta and combines them in a new system that will be superior in reliability, cost, weight, and capability. The government is working to determine its strategy for an American-made engine and future launch services. As they make those determinations we’ll adjust our strategy to make sure we’re aligned with the government’s objectives and goals.”

The in-flight failure of a critical support strut inside the second stage liquid oxygen tank holding a high pressure helium tank in the Falcon 9 rocket, is the likely cause of the failed SpaceX launch three weeks ago on June 28, revealed SpaceX CEO and chief designer Elon Musk during a briefing for reporters held today, July 20, to explain why the critical cargo delivery run for NASA to the space station suddenly turned into a total disaster after a promising start.
The commercial booster and its cargo Dragon payload were unexpectedly destroyed by an overpressure event 139 seconds after a picture perfect blastoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida on June 28 at 10:21 a.m. EDT.
Musk emphasized that the failure analysis is still “preliminary” and an “initial assessment” based on the investigation thus far. SpaceX has led the investigation efforts under the oversight of the FAA with participation from prime customers NASA and the U.S. Air Force.
The root cause appears to be that the second stage strut holding the high pressure helium tank inside the 2nd stage broke at a bolt – far below its design specification and thereby allowing the tank to break free and swing away.
“The strut that we believe failed was designed and certified to handle 10,000 lbs of force, but failed at 2,000 lbs, a five-fold difference,” Musk explained.
“During acceleration of the rocket to 3.2 G’s, the strut holding down the helium tank failed. Helium was released, causing the over pressurization event.”
To date no other issues have been identified as possible failure modes, Musk elaborated.
The helium tanks are pressurized to 5500 psi and were breached during the over pressurization. The purpose of the helium tanks is to pressurize the first and second stage propellant tanks.

“We tested several hundred struts. On the outside they looked normal. But inside there was a problem,” Musk explained
“Detailed close-out photos of stage construction show no visible flaws or damage of any kind,” according to a SpaceX statement.
The struts are produced by an outside vendor that Musk would not identify. He added that in the future, SpaceX will likely choose a different vendor to manufacture the struts.
He said the struts were made from a type of stainless steel and would also likely be redesigned.
“The material of construction will be changed to Inconel,” Musk told me in response to a question.
Hundreds of the original type struts have been used to date on the first and second stages of the Falcon 9 with no issues. In the future, they will also be independently certified for use, by an outside contractor instead of the vendor.
The nine first stage Merlin 1D engines of the Falcon 9 were still firing nominally during the start of the mishap, said Musk. The first stage had nearly completed its planned firing duration when the explosion took place.
“The event happened very quickly, within 0.893 seconds,” Musk stated, from the first indication of an issue to loss of all telemetry.
“Preliminary analysis suggests the overpressure event in the upper stage liquid oxygen tank was initiated by a flawed piece of support hardware (a “strut”) inside the second stage,” noted SpaceX in a statement.

The blastoff of the Dragon CRS-7 cargo mission for NASA was the first failure of the SpaceX Falcon 9 rocket after 18 straight successes and the firms first launch mishap since the failure of a Falcon 1 in 2008.
The SpaceX CRS-7 Dragon was loaded with over 4,000 pounds (1987 kg) of research experiments, an EVA spacesuit, water filtration equipment, spare parts, gear, computer equipment, high pressure tanks of oxygen and nitrogen supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45.

The Dragon cargo freighter survived the explosion but was destroyed when it impacted the Atlantic Ocean.
“But the Dragon might have been saved if the parachutes had been deployed,” said Musk.
Unfortunately the software required to deploy the parachute was not loaded onboard.
“The new software required to deploy the parachutes will be included on all future Dragons, V1 and V2,” said Musk, referring to the cargo and crew versions of the SpaceX Dragon spaceship.

The NASA cargo was valued at about $110 million. The launch itself was not insured.
The investigation board is reviewing data from over 3,000 telemetry channels as well as video and physical debris, he noted.
The next launch of a Falcon 9 will be postponed at least a few months until “no earlier than September” Musk indicated.
Two Falcon 9 launches had been set for August from Vandenberg AFB and Cape Canaveral. And the next launch to the ISS had been slated for September on the Dragon CRS-8 mission.
Musk said the next payload to be launched aboard a Falcon 9 has yet to be determined.
Overall CRS-7 was the seventh SpaceX commercial resupply services mission and the eighth trip by a Dragon spacecraft to the station since 2012.
CRS-7 marked the company’s seventh operational resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the station during a dozen Dragon cargo spacecraft flights through 2016 under NASA’s original Commercial Resupply Services (CRS) contract.

“The accident was a huge blow to SpaceX,” Musk told the opening session of the International Space Station Research & Development Conference being held in Boston, Mass, during an on-stage conversation with NASA’s International Space Station manager Mike Suffredini.
Dragon was chock full of over two tons of research experiments and much needed supplies and gear for the multinational crews serving aboard.
“There’s still no clear theory that fits with all the data,” Musk said. “We take these missions incredibly seriously.”
The cargo ships function as a railroad to space and the lifeline to keep the station continuously crewed and functioning. Without periodic resupply by visiting vehicles the ISS cannot operate.
The SpaceX Falcon 9 and Dragon were destroyed just over two minutes after a stunning liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in sunny Florida at 10:21 a.m. EDT.
The upper stage of the rocket suddenly exploded due to an as yet unexplained anomaly as the nine first stage Merlin 1D engines kept firing. Moments later it vaporized into a grayish cloud at supersonic speed, raining debris down into the Atlantic Ocean.
Although the second stage appears to be the culprit in the disaster, Musk said that there is still not a coherent cause and explanation of the data and was hard to interpret.
“Whatever happened is clearly not a sort of simple, straightforward thing,” he explained. “In this case, the data does seem to be quite difficult to interpret.”
“So we want to spend as much time as possible just reviewing the data. No clear theory fits all the data.”
The Falcon 9 was transmitting data on over 3,000 channels of flight data streams.

Virtually since the moment of the mishap approximately 139 seconds after the otherwise successful launch, SpaceX engineers have been pouring over the data to try and determine the root cause of the accident.
“Everyone that can engage in the investigation at SpaceX is very, very focused on that,”Musk elaborated. “We want to spend as much time as possible just reviewing the data.”
From the beginning Musk indicated that there was some type of over pressure event in the upper stage liquid oxygen tank and he elaborated a bit at the conference.
“At this point, the only thing that’s really clear was there was some kind of over-pressure event in the upper stage liquid oxygen tank, but the exact cause and sequence of events, there’s still no clear theory that fits with all the data.”
“So we have to determine if some of the data is a measurement error of some kind, or if there’s actually a theory that matches what appear to be conflicting data points.”
SpaceX is conducting an intense and thorough investigation with the active support of various government agencies including the FAA, NASA and the U.S. Air Force.
“The interaction with NASA has been great so far,” Musk said. “The biggest challenge is that there are a lot of inquiries coming in simultaneously, so it’s hard to keep responding to everyone right away.”

The accident investigation is in full swing both at the Cape and SpaceX headquarters in Hawthorne, Ca.
Hans Koenigsmann, SpaceX VP of Mission Assurance, is leading the accident investigation for SpaceX.
“The process for determining the root cause of Sunday’s mishap is complex, and there is no one theory yet that is consistent with the data,” SpaceX spokesman John Taylor told me earlier.
“Our engineering teams are heads down reviewing every available piece of flight data as we work through a thorough fault tree analysis in order to identify root cause.”

The June 28 launch was the 19th overall for the Falcon 9 booster and the first failure in an otherwise hugely successful program by the new space company founded by Musk and headquartered in Hawthorne, CA. Musk’s oft stated goals include radically slashing the cost of access to space to enable much wider participation in the space frontier by entrepreneurs and individuals and foster much greater exploration that will aid human missions to the Red Planet.
SpaceX may have more to say publicly later this week.
“I think we’ll be able to say something more definitive towards the end of the week,” Musk noted.
In the meantime all SpaceX launches are on hold for several months at least.
Fortunately, the string of launch failures with the successful launch the Russian Progress 60 cargo freighter on July 3, five days after the SpaceX CRS-7 failure. Progress 60 docked at the ISS on July 5 with three tons of supplies, to the relief of the station partners worldwide.

KENNEDY SPACE CENTER, FL – SpaceX and NASA are diligently working to “identify the root cause” of the June 28 in flight failure of the firms Falcon 9 rocket, as the accident investigation team focuses on “flight data” rather than recovered debris as the best avenue for determining exactly what went wrong, a SpaceX spokesperson told Universe Today.
The SpaceX Falcon 9 booster broke up just minutes after a picture perfect blastoff from a seaside Florida launch pad on a critical mission for NASA bound for the International Space Station (ISS). It was carrying a SpaceX Dragon cargo freighter loaded with research equipment and new hardware to enable crewed spaceships to dock at the orbiting outpost.
The accident investigation team is still seeking the root cause of the launch failure through a complex fault tree analysis.
“The process for determining the root cause of Sunday’s mishap is complex, and there is no one theory yet that is consistent with the data,” said SpaceX spokesman John Taylor.
The accident investigation is in full swing both at the Cape and SpaceX headquarters in Hawthorne, Ca.
“Our engineering teams are heads down reviewing every available piece of flight data as we work through a thorough fault tree analysis in order to identify root cause.”

SpaceX is conducting an intense and thorough investigation with the active support of various government agencies including the FAA, NASA and the U.S. Air Force.
The SpaceX Falcon 9 and Dragon were destroyed just over two minutes after a stunning liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in sunny Florida at 10:21 a.m. EDT.
The SpaceX CRS-7 cargo resupply mission to the ISS began flawlessly. The nine Merlin 1D engines powering the Falcon 9 rockets first stage were firing nominally at launch to produce about 1.3 million pounds of liftoff thrust for almost their entire duration.
However, approximately 139 seconds into the planned 159 second firing of the first stage engine, the majestic blastoff went awry as the upper stage of the vehicle experienced an as yet unexplained anomaly and suddenly exploded, vaporizing into a grayish cloud at supersonic speed and raining debris down into the Atlantic Ocean.

The Falcon 9 has transmitting data on over 3,000 channels of flight data streams.
But something went wrong apparently with the upper stage said SpaceX CEO Elon Musk.
“There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause,” tweeted Musk.
But why that happened and the vehicle disintegrated in mere seconds is still a mystery to be resolved through careful fault tree analysis of the data.
“Cause still unknown after several thousand engineering-hours of review. Now parsing data with a hex editor to recover final milliseconds.”
While SpaceX and Coast Guard ships have recovered some debris in the days since the launch mishap, the data streams are expected to be the most useful source of information to the investigation team.
Hex editors are being used to comb through the data.
A hex editor (or binary file editor or byte editor) is a type of computer program that allows for manipulation of the fundamental binary data that constitutes a computer file.
The name ‘hex’ comes from ‘hexadecimal’: a standard numerical format for representing binary data.
Some data was transmitted after the breakup.
The accident investigation teams are currently in the process of recreating the final milliseconds of the flight to give them some additional insights into what may have happened, when and why.

There are sufficient supplies on board the ISS to keep the crew continuing their mission until at least October 2015.
The SpaceX CRS-7 Dragon was loaded with over 4,000 pounds (1987 kg) of research experiments, an EVA spacesuit, water filtration equipment, spare parts, gear, computer equipment, high pressure tanks of oxygen and nitrogen supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45.
These included critical materials for the science and research investigations for the first ever one-year crew to serve aboard the ISS – comprising Scott Kelly and Mikhail Kornienko.
The Dragon was also packed with the first of two new International Docking Adapters (IDS’s) required for the new commercial crew space taxis to dock at the ISS starting in 2017.
Another Russian Progress vehicle is set to fly on the next resupply mission from the Baikonur Cosmodrome on Friday, July 3.

Meanwhile, search and recovery teams from SpaceX and the Coast Guard are scouring the ocean and beaches along the Florida Space Coast for any signs of potentially dangerous Falcon rocket debris that rained down from the sky into the Atlantic Ocean after the sudden explosion unexpectedly destroyed the vehicle barely two minutes after a sun drenched liftoff from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida at 10:21 a.m. EDT.
All appeared normal as the Falcon 9 booster and Dragon resupply spaceship were streaking skywards through majestically blue Florida skies when catastrophe struck at approximately 148 seconds after blastoff and the rocket exploded violently- utterly destroying the rocket ship and its two ton load of critical supplies heading to the astronauts and cosmonauts living on board the ISS.
The upper stage appeared to break up in flight as the nine first stage Merlin 1D engines were firing as planned and the rocket was arcing over.

But why that happened and the vehicle disintegrated in mere seconds is still a mystery which will take some time to resolve.
“Cause still unknown after several thousand engineering-hours of review. Now parsing data with a hex editor to recover final milliseconds,” tweeted SpaceX CEO Elon Musk.
Although the cause is unknown, Musk also announced that the failure might be related to a problem with the Falcon 9 upper stage. since the first stage engines were still firing as planned.
“There was an overpressure event in the upper stage liquid oxygen tank. Data suggests counterintuitive cause,” tweeted Musk.

The rocket was traveling about 5000 km/h at an altitude of 45 kilometers at the time of the mishap.
“Falcon 9 experienced a problem shortly before first stage shutdown. Will provide more info as soon as we review the data,” tweeted SpaceX CEO Elon Musk soon after the explosion.
The pressurized section of the Dragon was packed with over 4,000 pounds of research experiments, spare parts, gear, high pressure supply gases, food, water and clothing for the astronaut and cosmonaut crews comprising Expeditions 44 and 45 on the ISS.

Sunday’s launch was the 19th launch of the Falcon 9 rocket and the first failure after 18 straight successes.
SpaceX formed a failure investigation board immediately following the launch failure of the SpaceX Commercial Resupply Services 7 (CRS-7) mission bound for the ISS. The FAA and NASA will assist in the investigation.
The launch was the sixth for SpaceX this year, which had been picking up its launch pace dramatically compared to 2014.
