Memory Reformat Planned for
Opportunity Mars Rover (Source: NASA JPL)
An increasing frequency of computer resets on NASA's Mars Exploration
Rover Opportunity has prompted the rover team to make plans to reformat
the rover's flash memory. The resets, including a dozen this month,
interfere with the rover's planned science activities, even though
recovery from each incident is completed within a day or two.
Flash memory retains data even when power is off. It is the type used
for storing photos and songs on smart phones or digital cameras, among
many other uses. Individual cells within a flash memory sector can wear
out from repeated use. Reformatting clears the memory while identifying
bad cells and flagging them to be avoided. (8/29)
Curiosity, Cassini Among 7 Extended
Planetary Missions (Source: Space News)
NASA approved extensions for all seven missions that were vetted by
senior scientists in the agency’s 2014 senior review of operating
planetary science missions, a senior NASA official told SpaceNews Aug.
27. “We sent out the letters to the projects [and] those letters state
that we’re not canceling any missions,” Jim Green, NASA’s Planetary
Science Division Director, said after a meeting at the National
Research Council in Washington.
Green declined to discuss specifics, although he did say NASA would
force some of the missions to run “leaner and meaner [by] cutting back
in various aspects.” The details of the senior review board’s findings,
and NASA’s formal response to those findings, is to be released the

JAXA Asks for Withdrawal of Article on
Hayabusa (Source: Japan News)
The space agency said Friday that it has requested the withdrawal of an
article published in U.S. journal Science that was based on observation
data from its Hayabusa asteroid probe. The article, published in June
2006, contained an error in the data analysis method, the Japan
Aerospace Exploration Agency, or JAXA, said. But the mistake was not
made deliberately and should not be regarded as research misconduct, it
said.
The article was lead authored by Tatsuaki Okada, associate professor at
JAXA’s Institute of Space and Astronautical Science. Based on
observation data for the asteroid Itokawa, collected with X-ray
equipment on Hayabusa, the article made the assumption that the
elements constituting Itokawa would have the same composition as those
of meteorites showering Earth. The error was discovered during a review
of the data analysis method in the wake of a failure of similar
observation equipment. (8/29)
Looming SLS Delay To Rekindle Debate
about NASA’s Priorities (Source: Space News)
A long-running debate between the White House and Congress about
funding levels and prioritization of NASA programs entered a new phase
last week after a major cost and schedule review concluded the debut of
the Space Launch System heavy-lift rocket may be delayed by nearly a
year. The review established an estimated cost of $7.021 billion for
SLS development from February 2014 through its first launch.
That is in addition to the several billion dollars NASA has spent on
the rocket since being ordered by Congress in 2010 to build it. In a
teleconference with reporters, William Gerstenmaier, NASA associate
administrator for human exploration and operations, said the SLS
project was still working toward an earlier launch date than November
2018 by mitigating risks raised in the review. “If we don’t do
anything, we basically have a 70 percent chance of getting to that
date,” he said. “We will be there by November of 2018, but I look to my
team to do better than that.” (8/29)

the nation is willing to capitulate on this particular disaster
scenario.
“The exchange of information between crisis centers of Russia’s EMERCOM

the United States and the Russian Federation has begun,” said an
EMERCOM statement on Friday. Generally, this “exchange of information”
will cover large-scale natural and man-made disasters. Both FEMA and
EMERCOM (Russian Emergency Situations Ministry) “also agreed on
cooperating to protect their populations and infrastructures from
asteroid and comet hazards and on rescue work at mining facilities.”

Scrub of AsiaSat 6 Could Impact SpaceX
Mission to Space Station (Source: SpaceFlight Insider)
The launch of a commercial satellite, AsiaSat-6, has become one of the
factors as to whether-or-not SpaceX’s Dragon spacecraft will take to
the skies on Sep. 19 as is currently planned. With the recent delay of
the AsiaSat 6 flight, the U.S. Air Force’s Eastern Range could
potentially see as many three launches – in a time span of about ten
days. A KSC spokesperson said that, at present, NASA is moving forward
with plans to launch the fourth operational flight to the space station
and the fifth flight of the Dragon overall.
“We’re still moving forward with the September 19 launch date. SpaceX
says they need a little time to validate some things with their Falcon
9,” said NASA Spokesperson George Diller. “However, if they can launch
the F9 with AsiaSat 6 by the middle of the month – we should still be
able to carry out the mission on September 19.”
SpaceX's statement on the AsiaSat delay suggests that it could be as
long as two weeks. If it is just two weeks, then there should not be a
conflict on the Eastern Range (United Launch Alliance has the launch of
the CLIO spacecraft slated to take place on Aug. 16, with the CRS-4
mission scheduled to take place three days later). Normally, the U.S.
Air Force requires 2-3 days to reset the range to support a launch.

The West Wind Blows Afresh
(Source: Economist)
It takes chutzpah to tweet “rockets are tricky” shortly after one you
have just launched has deliberately blown itself up. But Elon Musk is
not a man who lacks self-confidence, and he did just that on Aug. 22
after the terminal malfunction a Falcon 9 vehicle. That Arianespace
announced on the same day that two satellites it had tried to launch to
join the Galileo constellation (intended to rival America’s GPS), had
entered a “non-nominal injection orbit”—in other words, gone
wrong—shows just how difficult the commercialisation of space can be.
If spacecraft are so precarious, then perhaps investors should lower
their sights. But not in terms of innovation; rather in altitude.
Airbus, a European aerospace company, thinks that developing
satellite-like capabilities without satellites is the answer. Hence the
firm’s recent trial, at an undisclosed location (but one subject to
Brazilian airspace regulations) of Zephyr 7, a high-altitude
“pseudo-satellite”, or HAPS for short.
Zephyr is actually an unmanned, ultralight, solar-powered,
propeller-driven aircraft. But it is designed, just as some satellites
are, to hover indefinitely over the same part of the world. With a
23-meter wingspan and a weight of only 50kg, it is fragile and must
remain above the ravages of the weather and the jet stream both by day
and by night. It therefore flies at an altitude of around 21km during
daylight hours, and then glides slowly down to around 15km when the sun
is unavailable to keep it aloft. (8/29)
Capitol Hill Reacts to SLS Delay
(Source: Space News)
In the wake of a review of the Space Launch System heavy-lift rocket
that likely pushes its first launch into 2018, two key House members
argued that NASA and the Obama administration were not adequately
funding the program, while one of the agency’s biggest advocates in the
Senate sought support for accelerating that schedule. In a letter
released Aug. 28, Reps. Lamar Smith (R-TX) and Steven Palazzo (R-MS),
the chairmen of the full House Science Committee and its space
subcommittee, respectively, asked NASA Administrator Charles Bolden for
additional details.
The letter does not explicitly mention the latest NASA review, but
instead references a July report by the U.S. Government Accountability
Office on potential SLS delays, as well as recent comments by Orion
program manager Mark Geyer that he was “struggling” to make a December
2017 launch date. “These findings are surprising to say the least
considering the numerous claims of sufficient funding,” Smith and
Palazzo write in the letter. “Despite numerous statements over several
years that these two national priority programs are sufficiently
funded, it now appears that this may not be the case.”
In a brief statement late Aug. 27, Sen. Bill Nelson (D-Fla.), chairman
of the Senate Commerce space subcommittee, offered a more positive spin
on the review. “Technically things look good,” he said. “But we need to
keep the budget on track so NASA can meet an earlier readiness date —
which I think can be done.” (8/29)
U.S. To Keep Closer Watch for Debris

A 25-Year Lock on Lucrative NASA work?
Time to Open Field to Competition (Source: Washington Business
Journal)
The Government Accountability Office has said on many occasions that an
agency is not required to neutralize or eliminate the natural
competitive advantage that an incumbent carries into a competition. In
this case, the agency decides that it would promote greater competition
if it could neutralize the competitive advantage of a 25-year
incumbent. The incumbent protested the terms of a solicitation that did
just that.
NMSU has been a 25-year incumbent on a contract for the operation and
maintenance of NASA’s Columbia Scientific Balloon Facility, as well as
several other balloon launch facilities at various locations worldwide.
NMSU protested that the RFP improperly excludes from competition or
evaluation the cost of various elements of the agency’s requirements.
NASA has apparently been concerned for several years with NMSU’s
exclusive teaming agreement with the only balloon manufacturer that is
acceptable to NASA for work on this project. Click here.

Sparks Fly as NASA Pushes the Limits
of 3-D Printing Technology (Source: NASA)
NASA has successfully tested the most complex rocket engine parts ever
designed by the agency and printed with additive manufacturing, or 3-D
printing, on a test stand at NASA's Marshall Space Flight Center. NASA
engineers pushed the limits of technology by designing a rocket engine
injector --a highly complex part that sends propellant into the engine
-- with design features that took advantage of 3-D printing. To make
the parts, the design was entered into the 3-D printer's computer. The
printer then built each part by layering metal powder and fusing it
together with a laser, a process known as selective laser melting.
The additive manufacturing process allowed rocket designers to create
an injector with 40 individual spray elements, all printed as a single
component rather than manufactured individually. The part was similar
in size to injectors that power small rocket engines and similar in
design to injectors for large engines, such as the RS-25 engine that
will power NASA's Space Launch System (SLS) rocket, the heavy-lift,
exploration class rocket under development to take humans beyond Earth
orbit and to Mars. (8/29)
