Forget “Manned”
Missions—Females May Be More Mentally Resilient in Deep Space
(Source: Scientific American)
Just past the confines of Earth’s geomagnetic field, deep space gets
downright nasty. There, cosmic radiation from solar flares, supernovae,
supermassive black holes and other powerful astrophysical phenomena
could spark cancer, vision loss and impaired thinking in future
astronauts voyaging to the moon, Mars or beyond.
But a new NASA-funded study published in Brain, Behavior and Immunity
makes a bold claim: When exposed to cosmic radiation, women may have an
innate biological capacity to stave off associated cognitive declines.
A team of researchers at the University of California, San Francisco,
(U.C.S.F.) and at Brookhaven National Laboratory found female mice
somehow kept clear heads after dangerous doses of radiation whereas
males developed obvious cognitive impairment. The group may have also
discovered the reason why—which could help create “vaccines” to
inoculate humans against radiation’s worst effects on the brain.
In the study Brookhaven scientists bombarded an equal number of male
and female mice with a potent mix of radioactive particles mimicking
those that suffuse deep space—such as high-energy atomic nuclei of
oxygen, helium and hydrogen. These particles and others like them
ping-pong through the void beyond Earth’s protective magnetic bubble,
and some are even channeled into the Van Allen Belts—a zone of seething
radiation that girdles our globe. Only 24 human beings have ever
traversed this treacherous territory: the Apollo astronauts, who sped
through the belts en route to the moon. (8/24)
Don’t Be Fooled by North
Korea’s Dismantling of Rocket Test Site (Sources: Heritage
Foundation, The Hill)
Satellite imagery indicates North Korea has begun to dismantle its
Sohae rocket engine test facility and space vehicle launch stand. The
dismantlement is a welcome, though limited, development, because
Pyongyang indicated the site was no longer necessary after having
successfully completed its missile and nuclear programs. In April,
North Korean leader Kim Jong Un declared that “we no longer need any
nuclear tests, midrange and intercontinental ballistic rocket tests,
and the nuclear test site in the northern area has also completed its
mission.”
In recent years, Pyongyang shifted its focus away from missiles
requiring a fixed launch site, such as that at Sohae, and developed
missiles launched from mobile vehicles. Mobile missiles, including two
intercontinental ballistic missile variants that can reach the entire
continental United States, are more difficult to track and target
during hostilities. The apparent dismantlement, like the earlier
destruction of the tunnel entrances to the nuclear test site, is being
done without foreign on-site inspectors. More importantly, neither
activity reduces the North Korean arsenal, nor diminishes missile or
nuclear weapon production capabilities.
President Trump on Friday said he has asked Secretary of State Mike
Pompeo to put off his planned visit to North Korea and accused
Pyongyang of slow-walking efforts to dismantle its nuclear program.
Trump wrote in a tweet that a high-level visit is not appropriate at
“this time, because I feel we are not making sufficient progress with
respect to the denuclearization of the Korean Peninsula.” (8/24)

The government of Nova Scotia did not approve or reject the Maritime
Launch Services (MLS) Environmental Assessment report in its decision
yesterday. Instead, it’s asking MLS for more information in the form of
a “focus report.” The decision is one that MLS knew could happen. It
will certainly delay their plans, at least until next spring.
In the decision, Margaret Miller, the Nova Scotia Minister of
Environment stated “during the EA (environmental assessment) review,
concerns were raised regarding the potential impacts of the Project on:
water resources, soil, air quality, noise, flora and fauna, fish and
fish habitat, protected areas and parks, human health and contingency
planning. These concerns were raised through public and Mi’kmaq
submissions, as well as submissions by Nova Scotia Environment, Nova
Scotia Department of Lands and Forestry, Nova Scotia Department of
Fisheries and Aquaculture, Environment and Climate Change Canada,
Health Canada, Fisheries and Oceans Canada, and Department of National
Defense.”
The letter further states “the focus report shall examine potential
impacts of the Project on: water resources, soil, air quality, noise
flora and fauna, fish and fish habitat, protected areas and parks,
dangerous good management, waste management, human health and
contingency planning. The EA Administrator will provide you with
written terms of reference for the preparation of the focus report
within 25 days. Maritime Launch Services Ltd. will have up to one year
to submit the report. (8/24)
Brevard County's Plan to
Borrow $8 Million for Blue Origin Denied by Court (Source:
Florida Today)
A previously approved plan by Brevard County commissioners to borrow
money and pay for $8 million in economic incentives to rocketry company
Blue Origin was denied by a court this week. The 18th Judicial Circuit,
which covers Brevard and Seminole counties, ruled that the county and
North Brevard Development District were denied their plans to issue
bonds to cover incentives initially designed in 2015 to attract Blue
Origin and its New Glenn rocket factory to Kennedy Space Center's
Exploration Park. The plan to borrow money to pay the company wasn't
approved until December of last year.
Brevard County Attorney Eden Bentley said the opinion "means the county
may not issue bonds to fund the North Brevard Development District
economic incentive agreement with Blue Origin. The opinion does not
prohibit the grant payment to Blue Origin, but does prohibit using a
bond to obtain the funding to pay it." That means the North Brevard
Development District likely now will be making annual payments over six
years to Blue Origin without borrowing the money, leaving less in its
budget for other economic development projects. (8/23)

Missions Before He Was For Them (Source: Space.com)
In his new role as our nation's uppermost space leader, Vice President
Pence criticized the previous administration's cancelation of NASA's
Constellation program to replace the Space Shuttles with new rockets
for lunar exploration. But Phil Larson, a former White House advisor

independent, blue ribbon panel lead by former Lockheed Martin chairman
Norm Augustine found it to be on an unsustainable trajectory."
Larson also says Pence was against Constellation before he was for it.
A 2005 Space.com article describes how "a group of Republican lawmakers
led by Mike Pence of Indiana last week said the $104 billion to replace
the shuttles with a new spaceship and rockets to carry astronauts back
to the moon ought to be canceled to help pay to rebuild the

How the White House Plans
a Return to the Moon During a (Two-Term) Trump Presidency
(Source: Ars Technica)
The Trump administration has established NASA’s main human spaceflight
goal as a sustainable human return to the Moon, with eventual human
missions to Mars. During what amounted to a pep talk at Johnson Space
Center in Houston on Thursday, Vice President Mike Pence reiterated his
commitment to this goal.
“We’re also renewing our national commitment to discovery and to
exploration and to write the next great chapter of our nation’s journey
into space,” Pence said. “NASA will awe the world with our daring
heroes.” ... “Our administration is working tirelessly to put an
American crew aboard the lunar orbital platform before the end of
2024,” Pence said.
Unfortunately for presidents who serve at most two four-year terms,
government spaceflight during the modern era moves at a glacial pace.
No astronauts will walk on Mars during Trump’s presidency or even on
the Moon. Past presidents with ambitions for the Moon, Mars, or
asteroids have faced similar conundrums because it takes so long to
arrange funding for these plans, finalize designs, build and test, and
finally to fly. Long before astronauts take flight, a new
administration moves into the White House. (8/23)
DARPA Hopes for Budget
Compromise on Satellite Servicing Mission (Source: Space
News)
The launch of a robotic servicing spacecraft developed by the Defense
Advanced Research Projects Agency and satellite manufacturer SSL is at
risk of being delayed amid congressional concerns that the Air Force is
requesting funds to launch this mission earlier than needed. Senate
appropriators cut $209 million from the Air Force launch budget for
FY-2019 on grounds that the payload — DARPA’s Robotic Servicing of
Geosynchronous Satellites, or RSGS — will not be ready to fly to orbit
as projected, by spring 2021.
The Air Force said it would need to buy the launch during fiscal year
2019 to ensure RSGS can meet the schedule. DARPA is “working closely
with the Air Force to answer any questions House and Senate
appropriators may have as Congress goes forward in its budget
deliberations.” Appropriations raised concerns about the schedule of
the mission known as “Space Test Program-4” and justified the funding
cut as “early to need.” Parrish said the RSGS vehicle is “on track for
launch in 2021.” (8/23)

“Our initial strategy for the Office of Space Commerce involves four

Will Stratolaunch Operate
at the Cape Canaveral Spaceport? (Source: Orlando Sentinel)
Stratolaunch is planning to integrate its launch vehicles at its

and to manufacture in the Seattle area, said spokesman Alex Moji. But
the aircraft could potentially launch from any runway that would
accommodate it — including Kennedy Space Center’s 15,000-foot-long
runway at the Shuttle Landing Facility, which was home to space shuttle
arrivals until the program was retired in 2011.
Space Florida, state’s aerospace economic development arm, declined to

Does Stratolaunch Have a
Top Secret Purpose? (Source: Popular Mechanics)
Stratolaunch's appeal lies in the fact that it can use smaller, cheaper
rockets to reach orbit. As an airplane, Stratolaunch can also fly
around the bad weather that might ground a rocket taking off from a
stationary pad. But commercial satellites are typically not on a strict
timeline and can wait for weather to improve. This has led to some
speculation that Stratolaunch is in fact a Department of Defense
project hiding in plain sight.
Quartz compares the airplane to the Glomar Explorer, a deep sea
drilling ship ostensibly designed to harvest manganese ore from the
ocean floor. In reality, it was meant to salvage a sunken Soviet
nuclear-armed submarine on the bottom of the Pacific Ocean. The ship
was so large and unusual that it was impossible to construct in secret,
so it was simply built with a cover story. Could Stratolaunch be
similar project?
VPOTUS Mike Pence and SECAF Heather Wilson have both visited the
company’s facilities. Stratolaunch, the theory goes, could discretely
fly specialized payloads into space without the extensive preparation
necessary for ground-based rockets. The giant plane could be optimized
for unique payloads, including anti-satellite weapons, launching them
into space with little or no notice. Fixed rocket launch pads in
California, Florida, and elsewhere are vulnerable to sabotage and other
forms of attack, but Stratolaunch could operate from many secure
military air bases. (8/23)
