Manufacturers Say Congress' RD-180
Engine Replacement a Waste of Money (Source: National Defense)
Two candidates to replace a Russian-made rocket engine said they don't
need taxpayer dollars to complete work on a U.S. version of the RD-180.
In addition, a panel of engine makers at the Space Symposium expressed
lukewarm interest in vying for an initial $220 million pot of money
Congress allocated last year to end the dependence on the Russian-made
engine.
Blue Origin has fully funded its BE-4 rocket engine, which may be
integrated onto a new class of rockets manufactured by United Launch
Alliance, said its President Robert Meyerson. That isn't the case for
Aerojet Rocketdyne and its AR-1 engine, said Julie Van Kleek, vice
president of the company's advanced launch and space unit. It needs
some government funding to pay for development of the engine, she said.
SpaceX, which builds engines and rockets, said it has been working with
the Air Force on a request for information document, said Gwynne
Shotwell, the company's president and CEO. "I don't think the
government should pay for an engine. I think launch providers should
pay for their own engine or contract with others to build their I
engines. (4/14)
A New Rocket Engine by 2019? Air Force
Says No; Aerojet Rocketdyne Says Yes (Source: National Defense)
Lawmakers amended the 2015 National Defense Authorization Act to ban
the use of RD-180 engines after 2019, and allocating $220 million for
the development of a replacement engine. The Air Force and the nation’s
key space launch provider are expressing doubts that a deadline will be
met to replace a Russian-built rocket engine needed to loft heavy
national security satellites.
“I’m not sure 2019 is doable,” Air Force Secretary Deborah Lee James
said at a recent hearing on Capitol Hill. Meanwhile, one of the
nation’s leading rocket engine makers, Aerojet Rocketdyne, said it is
possible. “We agree that it’s aggressive, but it’s doable,” said Linda
Cova, Aerojet Rocketdyne’s executive director for hydrocarbon engines
programs, responding to James’ comments on the 2019 deadline. (4/15)
Space Commander: Launch Facilities
'Old and Creaky' (Source: National Defense)
The U.S. government is poised to welcome new rocket providers, but the
leader of U.S. Space Command said the nation's launch pads may not be
able to accommodate them. "Our ranges are structured today not to
support this kind of business," said Air Force Gen. John Hyten. "They
are old. They are creaky. ... [and] fragile."
Cape Canaveral in Florida and Vandenberg Air Force Base in California
will not support the manifests of SpaceX and ULA's newly announced
Vulcan family of rockets. The cape is doing about 40 launches this year
but that is the maximum it can handle, he noted.
"We have to build an automated flight safety system and get that
approved," he said. The Air Force has asked for funds since at least
2008 to modernize the system, but with commercial suppliers ready to
provide competition for both the military and private sector launches,
now it is imperative, he said. (4/15)
The Fate of ULA and its Vulcan Rocket
May Lie with Congress (Source: Denver Business Journal)
Colorado's United Launch Alliance faces a host of technical hurdles in
building its newly unveiled Vulcan rocket line. But ULA’s business
decision to forge ahead with a multi-billion-dollar rocket investment —
and ULA’s whole future in the rocket business — may rest on the most
unpredictable variable of all: Congress.
Tory Bruno, CEO of the Centennial-based rocket company, said Wednesday
that the ULA board wants Congress to decide whether it’ll relax import
restrictions on the Russian-made RD-180 engines for ULA’s existing
Atlas V rocket line before completely funding development of the new
Vulcan rockets.
“My board has said we will not approve fully funding the rocket all the
way through to completion until that [RD-180] uncertainty goes away.”
Bruno said, in an interview at the annual Space Symposium industry
conference in Colorado Springs. (4/15)
ARFL Confirms Feasibility of Reaction
Engines’ SABRE Engine Concept (Source: The Engineer)
Analysis undertaken by the United States’ Air Force Research Laboratory
has confirmed the feasibility of Reaction Engines’ Synergetic
Air-Breathing Rocket Engine (SABRE) engine cycle concept.
The analysis was undertaken by AFRL as part of a Cooperative Research
and Development Agreement (‘CRADA’) with the Air Force Research
Laboratory’s Aerospace Systems Directorate (AFRL/RQ) which was entered
into in January 2014. These investigations examined the thermodynamic
cycle of the SABRE concept and found no significant barrier to its
theoretical viability provided the engine component and integration
challenges are met.
According to a statement, Oxforshire-based Reaction Engines and AFRL
are now formulating plans for continued collaboration on the SABRE
engine; the proposed work will include investigation of vehicle
concepts based on a SABRE derived propulsion system, testing of SABRE
engine components and exploration of defence applications for Reaction
Engines’ heat exchanger technologies. (4/15)

ULA CEO Calls 2018 Availability Date
For AR-1 Engine ‘Ridiculous’ (Source: Aviation Week)
United Launch Alliance CEO Tory Bruno says Aerojet Rocketdyne’s claim
of delivering an AR-1 rocket engine capable of operating on the Atlas V
or Vulcan vehicles by 2018 is “ridiculous.” “It is not going to happen.
I would love for them to prove me wrong, but I just don’t think that is
realistic,” Bruno said. Until this week, Air Force officials were told
the AR-1 would be ready in 2019.
“They believe that they can do some clever things with new materials in
additive manufacturing and analytical models that shorten the
development cycle from what we have traditionally experienced. I
believe that they are overly optimistic. It is our assessment that they
are 1-2 years behind Blue Origin at this time.” (4/15)
ULA CEO Outlines BE-4 Engine Reuse
Economic Case (Source: Aviation Week)
ULA CEO Tory Bruno says his choice of planning to reuse only the BE-4
engines – not the entire first stage – of the company’s new Vulcan
rocket was driven purely by the economics. The cost equation also
favors the Blue Origin BE-4 engine, he says, because it employs “clean
burning” methane fuel, he says.
“It takes a good seven to eight reuses before you can pay off the
additional cost of all the extra equipment and the logistics of
recovering it and then bringing it back to the factory with a
reasonable amount of refurbishment that you have to do,” Bruno said.
“You can’t just dust it off and reuse it. You have got to do plumbing
and new cables and insulation and all this kind of stuff. Our
calculations say [it takes] 7-8 uses to break even … To really make it
worth while, you have really got to reuse it about 15 times.” (4/15)
SpaceX Checks Throttle Valve After
Flawed Falcon 9 Recovery Attempt (Source: Aviation Week)
SpaceX is thought to be focusing on static friction in an engine
throttle valve as the prime suspect for the loss of the Falcon 9 first
stage during the third attempt at recovering the booster. The Falcon 9
was seconds away from what would have been the first successful landing
of a used booster stage on SpaceX’s Autonomous Spaceport Drone Ship
(ASDS) when the vehicle toppled over and was destroyed.
Musk indicated that “the issue was stiction in the biprop throttle
valve, resulting in control system phase lag.” Musk was referring to
“stiction” — or static friction — in the valve controlling the
throttling of the engine. The friction appears to have momentarily
slowed the response of the engine, causing the control system to
command more of an extreme reaction from the propulsion system than was
required. As a result, the control system entered a form of hysteresis,
a condition in which the control response lags behind changes in the
effect causing it. (4/16)

Hours after launching a batch of cargo to the Space Station on Tuesday,
SpaceX wheeled another Falcon 9 rocket into the hangar at Cape
Canaveral for a commercial satellite launch set for April 27. If
engineers complete preparations on the rocket in time, SpaceX will

Early Earth May Have Absorbed
Mercury-Like Object (Source: Space.com)
A key ingredient of the early Earth may have been a chunk of rock much
like Mercury, scientists say. This finding could help explain how
Earth's magnetic field has lasted for billions of years, researchers
added. Scientists think Earth formed at about the same time as the sun
and the rest of the solar system about 4.6 billion years ago from a
giant, rotating cloud of gas and dust.
Earth and the other rocky planets coalesced from smaller asteroid-sized
bodies that accreted or stuck together to form ever-larger chunks of
rock. Earth's crust and mantle puzzlingly have a higher proportion of
the element samarium to the element neodymium than seen in most
meteorites. New experiments now suggest that the addition of a
sulfur-rich Mercury-like body to the early Earth could explain this
anomaly. This research could also help solve another mystery — how the
Earth's magnetic field has lasted for billions of years. (4/15)
1st Launch of Piloted Spacecraft From
Vostochny Center Postponed (Source: Sputnik)
The launch of the first piloted spacecraft from the Russian Vostochy
space complex will be postponed from 2018 to 2020, according space
industry and government sources. Russia's Deputy Prime Minister Dmitry
Rogozin and head of Russia's space agency Roscosmos Igor Komarov
suggested the postponement of the launch to President Putin in order to
avoid creating infrastructure for old spacecraft at the new space
center.
"This [creating sites for old spacecraft] is a waste of money because
later the infrastructure would have to be rebuilt for new ships and
tasks," a Roscosmos source told Kommersant. Putin reportedly agreed to
postpone the launch. (4/17)
Volusia Officials Try to Lure Blue
Origin to Oak Hill (Source: Daytona Beach News-Journal)
While local economic development officials wait to see what happens
next in their quest to lure an aerospace manufacturer to Volusia
County, the company they’ve been hoping to attract has been revealed as
Blue Origin, the private commercial space flight company owned by
Amazon founder Jeff Bezos. U.S. Senator Bill Nelson confirmed last week
that he personally has talked to Bezos.
Whether companies launch from Cape Canaveral or a future site at
Shiloh, Space Florida officials say the companies need nearby locations
for back door operations, such as manufacturing parks and refurbishing
the reusable rockets used in spaceflight. To that end, Volusia
officials hope to position sites — such as the Unatin property — for
that related manufacturing. Click here.
