String Field Theory Could be the
Foundation of Quantum Mechanics (Source: Space.com)
Two USC researchers have proposed a link between string field theory
and quantum mechanics that could open the door to using string field
theory - or a broader version of it, called M-theory - as the basis of
all physics. "This could solve the mystery of where quantum mechanics
comes from," said Itzhak Bars. Rather than use quantum mechanics to
validate string field theory, the researchers worked backwards and used
string field theory to try to validate quantum mechanics. (11/4)
Image Shows Never-Before-Seen Detail
in a Solar System Being Born (Source: Air & Space)
Astronomers at ALMA, the Atacama Large Millimeter/submillimeter Array,
have used the telescope's exquisite resolution to take the best-ever
picture of planet formation. In the image, young planet-like objects
are forming around HL Tau, a sun-like star about 450 million light
years away.
Gas and dust are swirling in a protoplanetary disk around the star,
slowly bumping and coalescing as gravity pulls them into more and more
substantial objects. Astronomers have never been able to see such
clearly defined gaps in the disk, which make it appear as a series of
rings. These gaps are made as the planets form and grow, pushing away
or sweeping up debris in their orbits. Click here.

The Break-Off Effect (Source:
Fast Company)
At first they thought it was asthma. The fighter squadron's 37-year-old
commander suddenly started refusing to fly at high altitudes because of
mysterious breathing problems. He also struggled to control feelings of
wrath toward his coworkers, and that made him hyperventilate. It was
only later that the commander would tell a Navy psychologist what
really triggered him: That while flying at the edge of the troposphere,
“a frightening feeling of detachment” set in. There, in the halo of
thin silence surrounding the earth in 1956, he didn’t trust his own
mind not to self-destruct.
The atmosphere gets threadbare above 45,000 feet. There are fewer
nitrogen and oxygen molecules to populate the air, the colors start to
deepen and change. Higher than that, at roughly 70,000 feet, some
pilots and engineers say you can grasp the curvature of the earth.
Strange things have happened to the human mind at those heights. A year
after the commander reported his symptoms, a Navy medical officer and a
psychologist published a study on a dissociative anomaly pilots
experienced while flying at high altitudes.
The “break-off" phenomenon, they called it. Not many pilots wanted to
tell shrinks about break-off. Talking about your feelings was the
opposite of what you were supposed to do as a hyper-masculine alpha
pilot. A few pilots were willing to take that risk. Of the pilots that
did report breaking-off, most felt peaceful, others totally euphoric.
And then there was the other group. More than a third of the break-off
pilots freaked out. Click here.

The Surreal Task of Landing on a Comet
(Source: Scientific American)
On November 12th 2014 the European Space Agency’s Rosetta mission will
eject the small robotic lander Philae on a trajectory that should take
it down to the surface of comet 67P/Churyumov-Gerasimenko (or 67P/C-P
for short). Already Rosetta is maneuvering from its 10 kilometer orbit
to get into the right place to deploy Philae.
The landing site is on the ‘head’ of the rubber-duck shaped cometary
nucleus (although it might also be likened to a half-eaten, and rather
rotten apple core). This target area has now been named ‘Agilkia’ after
an island in the Nile river here on Earth – a place where the ancient
Temple of Isis was moved to after its original island home of Philae
was flooded during the construction of the Aswan dam. Click here.

NASA Sites Across US Vulnerable to
Climate Change (Source: Phys.org)
NASA has been at the forefront of climate science, launching satellites
that take the pulse of Earth's land, oceans and atmospheric systems,
gathering data on climate, weather and natural hazards. But the agency
is increasingly vulnerable itself to the effects of a changing climate.
Hurricane Isabel partially flooded the Langley Research Center in
Virginia in 2003; Hurricane Frances damaged the Kennedy Space Center in
Florida in 2004; and Hurricane Katrina damaged buildings at the Stennis
Space Center in Mississippi in 2005, among recent incidents. Other
facilities have been damaged or threatened by tornadoes and wildfires.

Orbital Announces Go-Forward Plan for
Commercial Cargo and Antares (Source: Orbital)
Orbital Sciences Corp. announced comprehensive plans to fulfill its
contract commitments under NASA’s Commercial Resupply Services (CRS)
program as well as to accelerate an upgrade of the Antares launcher’s
propulsion system. Under the new approach, all remaining cargo will be
delivered to the International Space Station (ISS) by the end of 2016.
There will be no cost increase to NASA and only minor adjustments will
be needed to the cargo manifest.
An Accident Investigation Board (AIB) is addressing preliminary
evidence of a probable turbopump-related failure in one of the two
Aerojet Rocketdyne AJ26 stage one main engines. As a result, the use of
these engines for the Antares vehicle likely will be discontinued.
Orbital plans an early introduction of its previously selected Antares
propulsion system upgrade in 2016.
This will be preceded by one or two non-Antares launches of the
company’s Cygnus cargo spacecraft to the ISS in 2015-2016. In addition,
the company expects repairs to the Mid-Atlantic Regional Spaceport
(MARS) launch complex at NASA’s Wallops Flight Facility to be
undertaken quickly, allowing launch operations to continue at Wallops
Island with the upgraded Antares beginning in 2016. (11/5)
NASA Wants to Build Lytro's Camera
Tech Into Space Probes (Source: Mashable)
Lytro has big ambitions that go way beyond just selling a few
technically impressive cameras. The company behind the "shoot first,
focus later" camera wants nothing less than to evolve traditional the
entire field of photography with tools that incorporate depth,
dimensionality and computation.
To that end, Lytro is releasing a program to license its technology to
third parties. The Lytro Platform will enable businesses and government
agencies to build upon the company's unique imaging tech for
applications separate from consumer photography.
Lytro says one of the first organizations to buy the Lytro Development
Kit (LDK) is the Department of Defense, who has plans to adapt the
light-field camera to build better night-vision goggles. NASA is
another client, aiming to install the imaging tech into space probes.

Virgin Plans Continued Test Flights in
2015 (Source: Huffington Post)
The space tourism company that suffered a tragic setback when its
experimental rocket-powered spaceship broke apart over the California
desert could resume test flights as early as next summer if it can
finish building a replacement craft, its CEO said Wednesday. The sleek
composite shell and tail section of the new craft are sitting inside
the company's manufacturing facility in Mojave, California.
After more than two years of work, it's beginning to look like a
spaceship, but Virgin Galactic CEO George Whitesides said there's much
more to be done, from relatively simple things such as installing
windows to the more complex fitting of flight controls and other wiring.
The ship — dubbed SpaceShipTwo Serial No. 2 — will replace one that was
destroyed last week after its feathering system that controls descent
deployed prematurely and aerodynamic forces ripped it apart, killing
the co-pilot and seriously injuring the pilot. In the wake of the
accident, workers have focused on building the new ship. (11/5)

Parallel Universes May Interact With
And Affect Our Own Universe (Source: IFL Science)
The concept of parallel universes has been depicted frequently in
science fiction, without any real evidence that they actually exist.
Howard Wiseman of Griffith University in Australia led a team that
believes quantum theory allows for multiple versions of our universe to
exist and overlap, and even interact with one another on the quantum
level.
Studying the nuances of quantum theory can get tricky, as things behave
contrary to what would be expected from ordinary matter. Quantum states
of a system are believed to simultaneously exist in all possible
configurations until an observer forces it to adopt one state. Click here.

Virgin Galactic Pilot Defied the Odds
to Survive Crash (Source: LA Times)
At almost twice the height of Mt. Everest, the air is dangerously thin
and the temperature is about 70 degrees below zero. It was a real world
case of survival in the face of disaster, like the movie "Gravity."
Siebold managed to deploy his parachute and land in the Mojave Desert.
His shoulder was smashed and a fellow pilot described him as "pretty
banged up." He was discharged from the hospital Monday.
"The fact that he survived a descent of 50,000 feet is pretty amazing,"
said Paul Tackabury, a veteran test pilot who sat on the board of
directors of Scaled Composites until it was sold to Northrop Grumman
Corp. "You don't just jump out of aircraft at Mach 1 at over 50,000
feet without a spacesuit." Siebold's partner, 39-year-old copilot
Michael Alsbury, was found dead, strapped into his seat in the wreckage.
The exact details of Siebold's more than 10-mile fall are still
unknown. On Monday night, federal investigators said they still had not
been able to interview him. "We don't know how he got out," National
Transportation Safety Board spokesman Eric Weiss said Tuesday. (11/5)

Worlds Not So Far Apart (Source: Aviation Week)
Elon Musk seems to be successful in all his other businesses, be it
Tesla or SolarCity, implying he may have found a miracle recipe to
break through markets where incumbents—be they defense and space
conglomerates, car manufacturers or energy companies—have traditionally
crushed potentially disruptive entrants. So what could this miracle
recipe be?
Years ago, I was a consultant to a European startup that wanted to
revive the old Zeppelin’s rigid airship design on a large scale for
multiple applications, from freight transport to luxury passenger
cruises. At first glance, the idea was appealing, to bring back to life
a proven technology to offer an environment-friendly, safe, economical
and versatile mode of transportation that could help alleviate road and
airport congestion in the busiest parts of Europe. Yet the venture
never took off beyond preliminary studies.
In hindsight, four main reasons stand out: lack of resources, lack of
talent, no “system approach” and no “dream” to connect with. Just
reverse those causes for failure and you possibly have Elon Musk’s
recipe for success. The first two, while obvious, are not easy to get.
Not everybody has lots of cash to start a company and the charisma and
self-confidence to attract top talent. (11/3)

Dark Matter May Be Massive
(Source: Case Western)
The physics community has spent three decades searching for and finding
no evidence that dark matter is made of tiny exotic particles. Case
Western Reserve University theoretical physicists suggest researchers
consider looking for candidates more in the ordinary realm and, well,
more massive. Dark matter is unseen matter, that, combined with normal
matter, could create the gravity that, among other things, prevents
spinning galaxies from flying apart. Physicists calculate that dark
matter comprises 27 percent of the universe; normal matter 5 percent.

Leadership of Key Senate Committees (Source: Space News)
With the Republican Party winning control of the U.S. Senate, the new
leadership of key committees may take a different approach to some key
military space issues, although NASA is less likely to see a
significant shift there. Sen. John McCain (R-AZ) is widely expected to
assume the chairmanship of the Senate Armed Services Committee.
McCain has been a powerful and persistent advocate of competition in
the national security launch market. He also has been a vocal critic of
government launch services provider United Launch Alliance of Denver
the past two years. Additionally, McCain was the author of language in
the Senate’s defense authorization bill that would ultimately ban the
use of Russian engines, including the RD-180.
On the Senate Appropriations Committee’s defense subcommittee, Sen.
Thad Cochran (R-MS) is in line to take over chairmanship from Sen.
Richard Durbin (D-IL), who spent much time and effort working on
national security launch issues as well as questioning the Missile
Defense Agency. Durbin has been a strong advocate of increased
competition for national security launch missions. (11/5)
