The Fuzzball Fix for a Black Hole
Paradox (Source: WIRED)
In the late 18th century, the scientist John Michell pondered what
would happen if a star were so massive, and its gravity so strong, that
its escape velocity would be equivalent to the speed of light. He
concluded that any emitted light would be redirected inward, rendering
the star invisible. He called these hypothetical objects dark stars.
Michell’s 1784 treatise languished in quiet obscurity until it
resurfaced in the 1970s. By then, theoretical physicists were well
acquainted with black holes—the dark star idea translated into Albert
Einstein’s theory of gravity. Black holes have a boundary called an
event horizon that represents the point of no return, as well as a
singularity, a point of infinite density within. Click here.

What if Property Disputes Extend to
Space? (Source: Madison Journal)
Of course, there’s not a lot of talk about NASA now, because our
financial woes have stifled our space ambitions for the time being. But
the space age is far from dead. In fact, I think it’s quite the
opposite. But it’s entering a different, more fragmented age, in which
NASA might not be the dominant player. Our technology is getting better
and better. And this allows many individuals and groups of people to
join the game.
And there’s a lot of money above.
For instance, think about how much money is tied up in satellites right
now. If you have a dish, then you’re reliant on those signals from
satellites. You’re paying good money every month to someone who
maintains those satellites. Think about all the GPS systems.
Think about how satellite imagery is getting better and better. With
high-definition cameras from satellites aimed on the world, think of
all the money that can be made, all the information available to
individuals, businesses or governments. We have predator drones now.
But we’re working hard on laser technology, too. What if those drones
were eventually topped by a greater technology, lasers from satellites?

Japan to Launch New Group to Study
Extraterrestrial Materials (Source: Japan Times)
The Japan Aerospace Exploration Agency plans to launch a new
organization Wednesday specializing in the study of extraterrestrial
materials to further investigate how the solar system developed, agency
officials said Saturday. JAXA, as the agency is known, will establish
the new organization within its Institute of Space and Astronautical
Science in Sagamihara, Kanagawa Prefecture.
The group is expected to analyze mineral grains brought back to Earth
from the asteroid Itokawa by the Hayabusa probe, as well as rocks taken
from asteroid 1999 JU3 by the Hayabusa2, which is expected to arrive in
three years and return with the samples by the end of 2020. (6/27)
What Is the Space Program Good For?
(Source: Air & Space)
We look back on the Apollo era today and think that all Americans were
united in the quest to reach the moon. But it wasn’t necessarily so. On
October 10, 1968, the eve of the first crewed Apollo launch, rocket
pioneer and NASA executive Wernher von Braun addressed a group of
honorees and their families at a Manned Flight Awareness program dinner
at the Kennedy Space Center.
The MFA program, launched two years earlier as a recognition and
quality assurance program, had assumed even greater importance in the
wake of the Apollo 1 fire that took the lives of three astronauts in
January 1967. Following that tragedy, critics in Washington and in the
media had sharpened their attacks over the mounting cost and risks
associated with spaceflight, even as NASA regrouped and prepared to
return to flight. Click here.

U.S. Air Force Mulls Plans to Replace
Russian Rocket Engines (Source: Reuters)
A U.S. Air Force competition to develop a rocket propulsion system to
end dependence on Russian rocket engines drew broad response from
companies, the Air Force said on Friday. “There is interest,” Lt.
General Samuel Greaves, who heads the Air Force’s Space and Missiles
Systems Center, said during a webcast hearing of the House Strategic
Forces Subcommittee.
Congress has banned imports of the RD-180 as part of trade sanctions
against Russia for its involvement in Ukraine. “We do not have the
capability within the United States today to replace (the RD-180)
engine, so whatever we come up with will be a new engine,” Greaves
said. Click here.

How to Become an Astronaut
(Source: Aol)
When you were a child, what did you want to be when you grew up? When
the BBC asked 14,000 children about their ambitions back in 1969, many
mentioned becoming an astronaut - and many more reckoned they'd at
least be able to holiday on the moon. However a recent survey showed
that only 1% of today's children harbor the same career ambition, the
same number as want to be politicians or work in retail. Click here.

BRAC, Budget Dominate Summit Discussion
(Source: Military Times)
Another round of base realignments and closures looks to be out of the
question for now, but BRAC — and its potential costs — dominated some
discussions at a summit on the future of military communities. The
Association of Defense Communities summit was the backdrop for
exchanging ideas on how the private sector could get more involved in
the installations of the future, to the point of perhaps even managing
military bases.
Ongoing talk of budget constraints in the near future has led the
Defense Department and the services to seek another BRAC round, to
reduce unneeded infrastructure that costs precious dollars to maintain.
But Congress is standing firm against that idea, even as budget
constraints complicate efforts to operate and maintain bases, summit
participants said.
If the current budget climate rolls on over the next few years, base
facilities will be increasingly at risk, said Robert Hale, former DoD
comptroller. Some facilities already are failing, said John Conger,
acting assistant secretary of defense for energy, installations and
environment. Hale said he thinks another BRAC round will happen
eventually, focusing on depots, as well as "significant
underutilization" of some military hospitals. (6/26)
Here’s Why Coca-Cola is Investing in
OneWeb (Source: Space News)
Whether Internet goes better with Coke is anyone’s guess, but Coke is
going with OneWeb. The giant soft drink maker is an equity investor in
OneWeb LLC and one of the surprises of the June 25 OneWeb briefing on
London. Coca-Cola was not there to explain its decision, but OneWeb
founder Greg Wyler said the company has a program called Five by 20
that seeks to promote women’s employment in areas of the world where
OneWeb will have connectivity.
Wyler said Coca-Cola has 25 million sales and distribution points
around the world, including remote rural areas where OneWeb’s core
market resides. The OneWeb-Coke Ekocenters will put OneWeb terminals
atop a snack bar, serving both companies’ interests. (6/26)

Sierra Nevada Matures Dream Chaser
Thermal Protection System (Source: SNC)
Sierra Nevada Corp. has successfully completed several significant
Thermal Protection System (TPS) material development tests for its
Dream Chaser spacecraft. The TPS is responsible for protecting crew
members and cargo from the high temperatures the spacecraft will
experience during re-entry.
The TPS tests were completed at NASA’s Ames Research Center and Johnson
Space Center under reimbursable Space Act Agreements (SAA). The tests
provided critical data needed to support the upcoming TPS subsystem
Critical Design Review (CDR) and to validate Dream Chaser TPS
manufacturing readiness. Additional TPS certification testing is also
planned at the centers beginning in the fall of 2015. The Dream Chaser
tiles are being manufactured on Florida's Space Coast. (6/26)
Lawmaker Wants U.S. Air Force to Focus
on New Engine, Period (Source: Space News)
The chairman the House Armed Services strategic forces subcommittee
wants the U.S. Air Force and launch industry to focus narrowly on
replacing the Russian-made main engine on United Launch Alliance’s
workhorse Atlas 5 rocket, as opposed to investing in various launch
vehicle technologies.
Rep. Mike Rogers (R-AL) pointed out that Congress authorized $220
million in 2015 specifically for a new engine. But the Air Force, wary
of investing in an engine that none of its certified launch service
providers — currently ULA and newcomer SpaceX — wants, has proposed
spending that money more broadly on launch vehicle technology.
Editor's Note:
As with NASA's Space Launch System, this is an example of Congressional
Republicans ignoring their usual faith in the wisdom of industry and
instead opting for a government-driven, taxpayer funded solution. (6/26)

Russia Aims for Moon Landing, Leaves
Mars to NASA (Source: Bloomberg)
Russia’s state space agency chief is shooting for the Moon, three years
after a predecessor warned that the country was on the verge of losing
its competitiveness in the industry. A manned lunar mission in
2029-2030 is Russia’s priority, while there are no “current stage”
plans for a journey to Mars, Igor Komarov, head of the Federal Space
Agency or Roscosmos, said in an interview in St. Petersburg last week.
“NASA has Mars as the priority,” Komarov said. “We at this stage are
making the Moon our priority. We can be good in rounding each other out
and working jointly on this program.” Komarov’s ambition of landing a
Russian on the Moon contrasts with former Roscosmos chief Vladimir
Popovkin’s warning in 2012 that the country’s space industry risked
being uncompetitive within three or four years without “urgent
measures.” (6/26)
Alan Stern's Worldly Ventures
(Source: Science)
Alan Stern's salesmanship helped get New Horizons to Pluto. He has a
few other things for sale as well: a trip to the moon for $1.55
billion, and naming rights to a crater on Mars for $5. Those are the
signature products of Golden Spike and Uwingu, two of his companies.
Golden Spike plans to send a two-seat lander to the moon, staging
material in Earth orbit using commercial rockets. Governments with
space ambitions—the target customers—have not lined up to buy tickets,
but Stern insists that the company has made progress. “Absence of
evidence is not evidence of absence,” he says.
Uwingu has had more immediate impact, albeit on a smaller scale. Uwingu
raises money for space research through campaigns, such as selling
naming rights to martian craters on an unofficial Uwingu map (the
bigger the crater, the more expensive the name). Founded in 2012 with a
nearly $80,000 crowdsourcing campaign, Uwingu is a for-profit company.
Half of the revenues go into a fund for scientific grants—between
$130,000 and $150,000 in 2014, Stern says. (6/26)
SpaceX is on a Roll, But Here’s Why
the Pressure is Really On (Source: Washington Post)
It exploded seconds after takeoff, the majesty of a rocket launch
erupting suddenly into a shrapnel-spewing fireball. Then, months later,
another unmanned launch went catastrophically awry: A Russian rocket
spun wildly out of control after it reached orbit, eventually burning
up in the atmosphere as it crashed back to Earth.
Two rockets incinerated. Millions of dollars wasted. Several tons of
food and cargo destined for the International Space Station gone. Now,
Elon Musk’s SpaceX is preparing to resupply the orbiting laboratory on
Sunday. And with the failures of the Orbital ATK Antares rocket and
Russia’s Progress 59 spacecraft, the pressure is on. Not just for the
billionaire’s upstart space company, and its streak of seven straight
successful launches to the station, but the future of the private space
industry that SpaceX’s improbable success has helped spawn. (6/26)
