Musk Seeking Mars Mission After NASA
Picks SpaceX-Boeing (Source: Bloomberg)
With one small step yesterday, NASA took a giant leap toward realizing
a manned mission to Mars. The agency awarded Boeing and SpaceX as much
as $6.8 billion to ferry astronauts to the International Space Station,
resuming U.S. manned space flight. Since NASA retired the space shuttle
fleet in 2011, U.S. astronauts have relied on Russian rockets to reach
orbit.
While NASA is looking to private industry for human missions near Earth
with reusable craft, it can now focus on far-off trips such as Mars.
The space agency is preparing the first rockets to take humans beyond
low-Earth orbit in four decades. It's a goal shared by Elon Musk. He
said welcomes NASA's decision and "the mission it advances with
gratitude and seriousness of purpose. It is a vital step in a journey
that will ultimately take us to the stars and make humanity a
multi-planet species." (9/17)
Jeff Bezos Declares War on Elon Musk
(Source: Bloomberg)
Jeff Bezos and Elon Musk are officially at war. And how. On Wednesday,
Bezos presided over a press conference in which his rocket company Blue
Origin formed a partnership with United Launch Alliance, or ULA. The
deal between the companies will see Blue Origin develop an engine for
use with ULA’s rockets, which currently carry U.S. government and
military satellites to space. The deal helps ULA save face, because it
gives the company access to an American-made engine instead of the
Russian-made RD-180, on which it currently relies.
The tie-up also unites two of the staunchest rivals to SpaceX, Elon
Musk’s rocket company. Blue Origin, by contrast, has operated in
near-total secrecy and dribbled out information only about its engine
and rocket development. With Bezos’s fortune behind it, the company has
been free to hone its technology without chasing commercial work.
Blue Origin has been working on an engine called BE-4 for three years,
and it’s this engine that ULA plans to use with its rockets. During the
press conference, ULA’s new chief executive, Tory Bruno, said the
company hopes to launch the BE-4 in about four years. (9/17)
ULA To Invest in Blue Origin Engine as
RD-180 Replacement for Atlas 5 (Source: Space News)
United Launch Alliance will pay Blue Origin an unspecified sum to
complete development of a new engine that will replace the Russian-made
RD-180 that powers the first stage of ULA’s Atlas 5 rocket. Blue Origin
has been developing the BE-4 for three years, thus giving it a head
start against other prospective RD-180 replacements, ULA Chief
Executive Tory Bruno said.
Fueled by liquefied natural gas, the new engine will be relatively
inexpensive and could be ready to start flying in four years, he said.
Bruno said developing a new engine typically takes seven to 10 years
and costs $1 billion. Two BE-4 engines generating a combined 1.1
million pounds of thrust at sea level would power the Atlas 5 first
stage, Bruno said. The current Atlas 5 first stage is powered by a
single RD-180 generating close to 1 million pounds of thrust.
Bezos said the BE-4, which will generate about 550,000 pounds of
thrust, is based on the BE-3 that powers Blue Origin’s New Shepard, an
experimental suborbital rocket that takes off and lands vertically. In
addition to the Atlas 5, the new engine also would be used for a future
reusable orbital launcher Blue Origin plans to develop, he said. (9/17)
Blue Origin Engine Beat Aerojet
Rocketdyne Engine in ULA Competition (Source: Space News)
In June, ULA announced that it had signed contracts with multiple
unspecified companies to study alternatives to the RD-180. The company
declined to identify any of the contract recipients but said a first
launch of the new engine was targeted for 2019. ULA's Tony Bruno said
the BE-4 came out as the winner in that competition.
Among the other study contract recipients was Aerojet Rocketdyne, which
has been touting a liquid-oxygen/kerosene-fueled engine dubbed the AR-1
as an RD-180 replacement. Officials with Aerojet Rocketdyne, the
largest and most experienced U.S. manufacturer of liquid-fueled rocket
engines, said the AR-1 will be capable of generating 500,000 pounds of
thrust and could be ready to fly by 2019 for an investment of less than
$1 billion.
Congress, meanwhile, has proposed spending as much as $220 million next
year to begin work on a new engine. Editor's Note:
Private-sector options in development now, one wonders why the Federal
Government must invest taxpayer dollars for a new engine. (9/17)
Commentary on ULA/Blue Origin Engine
Link-Up (Source: SPACErePORT)
Traditional rocket engine manufacturers are a dwindling breed after the
series of consolidations that brought together Rocketdyne, Pratt &
Whitney, and Aerojet into a company now called "Aerojet Rocketdyne."
These longtime government contractors developed engines at higher costs
than newcomers like SpaceX.
By building its own rocket engines -- nine on each Falcon first-stage
plus more on upper stage and Dragon vehicles -- SpaceX claims now to be
the world's largest engine producer. ULA is a major customer for
Aerojet Rocketdyne, but its pursuit of partnerships
with XCOR and now Blue Origin gives the company some NewSpace cred
while benefitting from some of the cost-cutting approaches and
innovations they bring to the table. (9/17)

Astronomers have just discovered the smallest known galaxy that harbors
a huge, supermassive black hole at its core. The relatively nearby
dwarf galaxy may house a supermassive black hole at its heart equal in

Wanted by NASA: Space Telescope
Director with Spy Credentials (Source: Scientific American)
Conspiracy theorists may wonder, why does NASA’s next major telescope
director need top secret clearance? The space agency recently posted a
want ad for a person to lead its James Webb Space Telescope (JWST)
program, and in addition to aerospace engineering credentials and
management experience, the candidate must have the highest possible
level of security credentials.
CIA analyst Allen Aftergood speculated that the requirement likely had
to do with the interface between Webb’s technology and that used in
intelligence and military Earth-observing satellites. “I think it
probably reflects the role of surveillance technology and the need for
coordination with U.S. intelligence agencies,” he says. (9/17)

Iridium Communications’ request that U.S. regulators loosen

will still permit the company to bring down all of its satellites
within a few years of their retirement, company officials said. And for
most of the satellites, the post-retirement deorbit plan remains what
it was from the start: They will be lowered to an elliptical orbit low
enough to force them into the atmosphere to burn up within months, not

A $90 Ticket Into Space?
(Source: UT San Diego)
A new San Diego startup is charging people $90 to enter a contest whose
winners will be offered a free trip into space even though such
commercial flights aren't available to the general public. Spaceship
Earth Grants (SEG) began accepting applications on Monday with the hope
that Richard Branson’s Virgin Galactic or another company will develop
a safe, reliable spaceship to carry passengers on sub-orbital flights.
SEG says it will award one spaceflight for every 50,000 applications,
increasing the frequency if the pool gets large. The company is still
working out key details of the contest, including precisely how winners
will be chosen and how they will be trained for flights that must reach
an altitude of about 62 miles to reach the edge of space.
Editor's Note:
This is an interesting approach but it seems awfully similar to a
raffle. Raffles for spaceflight have been shut down in recent years for
legal reasons. By making this a judged contest SEG may successfully
avoid the raffle trap. (9/17)

Editorial: Keep Money, Momentum Behind
Private Space Plan (Source: Orlando Sentinel)
America's manned space program, in suspended animation for three years,
was stirring this week. That's promising for the program and the nation
— particularly for Florida, the nation's spaceport. But Congress must
make sure it doesn't postpone the program's reawakening — and America's
declaration of independence from Russia in space.
On Tuesday NASA awarded $6.8 billion in contracts to Boeing and SpaceX
for the two companies to finish developing their own space vehicles to
carry U.S. astronauts to and from the International Space Station by
2017. Both companies plan to launch from Florida's Space Coast. NASA's
decision to pick two contractors, instead of one, was opposed by some
members of Congress, who contend it's a more expensive approach.
But having two contractors will maintain competition that should keep
costs down over the longer term and drive innovation. It also should
forestall the possibility that problems with one contractor's operation
will shut down the manned space program again. The program will need
sustained support to meet its target. The launch date could slip to
2018 or later if Congress maintains its maddening practice in recent
years of starving the program's budget. (9/17)
Radiation Blast Delays NASA
Spacecraft’s Arrival At Dwarf Planet Ceres (Source: Universe
Today)
NASA’s Dawn spacecraft experienced technical problems in the past week
that will force it to arrive at dwarf planet Ceres one month later than
planned. Controllers discovered Dawn was in safe mode Sep. 11 after
radiation disabled its ion engine, which uses electrical fields to
“push” the spacecraft along. The radiation stopped all engine thrusting
activities. The thrusting resumed Sep. 15 after controllers identified
and fixed the problem, but then they found another anomaly troubling
the spacecraft.
Dawn’s main antenna was also disabled, forcing the spacecraft to send
signals to Earth (a 53-minute roundtrip by light speed) through a
weaker secondary antenna and slowing communications. The cause of this
problem hasn’t been figured out yet, but controllers suspect radiation
affected the computer’s software. A computer reset has solved the
issue, NASA added. The spacecraft is now functioning normally. (9/17)
Lawmaker Calls for Changes to How FAA
is Funded (Source: The Hill)
House Transportation and Infrastructure Committee Chairman Rep. Bill
Shuster, R-PA, says the FAA needs stable funding to better serve the
industry and traveling public. The $63 billion measure currently
funding the agency will expire in September 2015. "The next FAA
reauthorization should be transformational," Shuster said. "We've got
to do something different. We need to lay the groundwork for the future
of U.S. aviation."
Editor's Note:
Seems like a good idea. The FAA is chronically underfunded, and its
space office is especially so. The agency also invests far too little
in R&D. And to complicate matters, Congress funds the FAA's space
activities from a separate appropriations budget, in Science as opposed
to Transportation, where the bulk of FAA's money comes from. (9/17)

NASA Hedges On Critical Suit Battery
Resupply (Source: America Space)
NASA has confirmed that the Extravehicular Mobility Unit (EMU) Long
Life Batteries (LLBs) will not be launching solely on SpX–4, as
originally planned. Instead, according to NASA, two of the four LLBs
have already been sent to Russia for launch aboard a Soyuz scheduled
for late September, after SpX–4. Since August, ISS maintenance EVAs
have been curtailed due to the current EMU battery issues, therefore
making the resupply of new EMU batteries a top priority for NASA.
Given the possibility of a launch delay of either SpaceX or Soyuz,
NASA’s decision to hedge and split the payload between the upcoming
SpaceX cargo flight and a later Soyuz flight appears prudent. Over a
month ago, a failure was discovered in one of the astronaut
Extravehicular Mobility Unit (EMU) Long Life Batteries (LLBs) that
concerned one of the battery’s parts. All electrical parts in the
life-support system, that is in the portable life-support system (PLSS)
and secondary oxygen pack (SOP), are burned-in.
Since all LLB fuses use the same burn-in procedure and test setup, the
concern was that other long-life batteries could have the same problem.
In early August, the crew began removing the LLB’s from the onboard
EMU’s to be returned to the ground, and replacement LLB’s were
scheduled for launch on SpaceX–4 in September 2014. (9/17)
Visualizing 4-Dimensional Asteroids
(Source: Scientific American)
One of the largest treasure troves of astronomical data comes from the
Sloan Digital Sky Survey (SDSS), an ongoing scan of the firmament that
began 15 years ago. Its catalog covers 35 percent of the sky and
contains multicolor observations of hundreds of millions of distinct
galaxies, stars and quasars. If a person were to attempt to
individually inspect each of these objects at a rate of one per second
through the workday, it would be a full-time job lasting over 60 years!
Fortunately, such individual inspection is not how astronomers work.
Instead, we use various specialized algorithms to automatically sift
through and categorize this vast data set and dream up novel
visualization schemes to make clear in a glance the relationships
between thousands or millions of individual objects. Click here.

Thanks To Putin, Space Travel Is About
American Prestige Again (Source: Business Insider)
The US is dispensing with the diplomatic niceties of the Soyuz flights.
Manned space travel is a matter of national prestige again. And if
Russian president Vladimir Putin really is girding himself for a
long-term struggle over the future of the European periphery — one that
brings him into constant indirect conflict with the US and the NATO
states — then at least US policymakers will have one less reason to
want to mollify him when a manned Dragon 2 capsule flies for the first
time this December.
Editor's Note:
Recently, Russia seems anxious to clarify that its rocket engines will
continue to be available to U.S. buyers. Too late. The Ukraine crisis
is pushing U.S. government and industry players toward eliminating
their reliance on Russia's excellent and cheap engines. This is as good
for U.S. economic development as it is bad for Russia's ailing
spaceflight sector. (9/17)
Chandra Finds Planet That Makes Star
Act Deceptively Old (Source: Space Daily)
"It is one of the most massive hot Jupiters known and one of the
closest to its host star, and these characteristics lead to unexpected
behavior. This planet is causing its host star to act old before its
time." Pillitteri's team determined WASP-18 is between 500 million and
2 billion years old, based on theoretical models and other data. While
this may sound old, it is considered young by astronomical standards.
By comparison, our sun is about 5 billion years old and thought to be
about halfway through its lifetime. Younger stars tend to be more
active, exhibiting stronger magnetic fields, larger flares, and more
intense X-ray emission than their older counterparts. Magnetic
activity, flaring, and X-ray emission are linked to the star's
rotation, which generally declines with age. However, when astronomers
took a long look with Chandra at WASP-18 they didn't detect any X-rays.
