What in the World Is
Metallic Hydrogen? (Source: Space.com)
Solid. Liquid. Gas. The materials that surround us in our normal,
everyday world are divided into three neat camps. Heat up a solid cube
of water (aka ice), and when it reaches a certain temperature, it
changes phases into a liquid. Keep cranking the heat, and eventually,
you'll have a gas: water vapor.
Every element and molecule has its own "phase diagram," a map of what
you should expect to encounter if you apply a specific temperature and
pressure to it. The diagram is unique to each element because it
depends on the precise atomic/molecular arrangement and how it
interacts with itself under various conditions, so it's up to
scientists to tease out these diagrams through arduous experimentation
and careful theory. (1/15)
King's Dream of Equality
Must Extend to Space Science (Source: Space.com)
Martin Luther King Jr. Day is a reminder of what King called "the
fierce urgency of now," of the need to act quickly and decisively for
the good of an inclusive America. It also serves as a summons from a
minister whose heavenly mission speaks to our urge to explore the
heavens. Few things would be a greater honor to King's memory, and
there is no greater way for us to also honor ourselves, than to make
space-based research as diverse as the world is.
Recruiting these men and women is no act of tokenism; we need the best
Americans, regardless of race or gender, to maximize the best of
America. These citizens are students at our colleges and universities,
pupils at our primary and secondary schools, and our dreamers — and
doers — throughout this country of 300 million people.
Now is the time to introduce these individuals to the power of
space-based research, continuing King's work. This is not the work of a
single day or of a single person, or even of a single generation. But
today — Martin Luther King Jr. Day — is a singular day honoring a
singular leader. It is a day to seize the moment. (1/15)
Shake-Up at Pentagon
Intelligence Agency Sparks Concern (Source: Foreign Policy)
When Kim Jong Un gears up to launch a ballistic missile, analysts at
the National Geospatial-Intelligence Agency comb through satellite
imagery, looking for distinct signs on the the ground in North Korea
indicating test preparations are underway. Now, the U.S. agency is in
the midst of a concentrated push—what some have called a
reorganization—emphasizing the use of advanced technology to do
analysis typically done by humans, five sources with knowledge of the
matter told Foreign Policy.
That shift in priorities is worrying some veteran imagery analysts who
fear that their jobs might drastically change, and the technology being
pushed isn’t mature enough to replace human skill and analytic
capability. Those working inside and with the agency say it’s unclear
exactly what the changes entail, but it’s scaring some employees, who
worry the reorganization is part of a push to move work done by human
analysts to artificial intelligence, and to outsource some of NGA’s
work. (1/15)
Air Force Launches New
Project to Update Missile-Warning Ground Software (Source:
Space News)
Air Force officials are talking to potential vendors this week about an
upcoming project to update the software used to control the military’s
missile-warning satellites and to analyze the data beamed from space.
The ground-based systems are the less exciting but nonetheless
important piece of the SBIRS space-based infrared surveillance
satellites that provide initial warning of a ballistic missile attack
on the United States, deployed forces and allies.
The plan is to shift the current ground software architecture — a
closed system developed by traditional defense contractors that is not
compatible with commercial software from competing vendors — to an
open-systems platform that the Air Force would own and update with new
technology as it becomes available.
The project is called “future operationally resilient ground
evolution,” or FORGE. It is part of a broader $173.5 million SBIRS
modernization plan. And it is one of several projects where Air Force
hopes to attract nontraditional vendors that can bring fresh ideas and
cutting-edge products. (1/15)
Bridenstine’s Bid to

Rep. James Bridenstine’s controversial nomination to head NASA faces
mounting troubles, and the uncertainty threatens to further delay
potentially major changes in agency programs favored by the White
House. For the second time in three months, the Senate Commerce
Committee on Thursday is expected to narrowly approve the Oklahoma
Republican on a party-line vote. His name never came up for floor
action in 2017 because not a single Senate Democrat signaled support
and Republican leaders were worried about rounding up the necessary

Boeing, SpaceX Have
Razor-Thin Margins to Fly Crew Missions in 2018 (Source:
Ars Technica)
Almost since the beginning of the commercial crew program in 2010, the
old and new titans of the aerospace industry have been locked in a race
to the launch pad. Boeing, with five decades of aerospace contracts,
represented the old guard. SpaceX, founded in 2002, offered a new,
leaner way of doing things.
Through the years, as other participants in the commercial crew program
fell away, Boeing and SpaceX remained on course to deliver US
astronauts into space. It has not been easy for either company or for
their sponsor, NASA. The space agency has only ever led the development
of four spacecraft that carried humans into orbit, and three of those
programs came in the 1960s, with the fourth and final vehicle in the
1970s—the space shuttle.
As both companies sought to climb this steep learning curve, they have
missed deadlines. An original deadline of 2015 melted away after some
key members of Congress diverted funds for the commercial crew program
to other NASA programs, notably the Space Launch System rocket. But in
recent years, Congress has fully funded the efforts by Boeing and
SpaceX, and they were told that would yield flights in 2017. (1/13)

Why Humans May Not Be
Ready for Commercial Space Travel (Source: Salon)
There’s an infinitely modifiable English analogy that's been floating
around for decades, which goes something like “You can take the person
out of the place, but you can’t take the place out of the person.” I
imagine that sometime in the future, humans will be repeating this
phrase with a new twist: “You can take the human out of Earth, but you
can’t take the Earth out of the human.” In terms of the human body and
its needs outside of our planet, this couldn’t be more true. Click here.

Our Chance to Boldly Go
(Source: The Sunday Times)
Britain’s space industry is a success story — a story of invention and
innovation, of enterprising spirit and global ambition. Space is
fundamental to our country; the space sector underpins industries worth
£250 billion to our economy, it enables the defence and security of our
nation, and empowers our society. Now, we are entering a period of
unparalleled opportunity for growth and the Government’s Space Industry
Bill is designed to help British-based businesses take advantage of
that opportunity.
We have already secured 6.5 percent of the global commercial space
market. But we want to increase our share to 10 per cent by 2030. To
achieve that, we aim to make Britain the most attractive hub in Europe
for commercial spaceflights. (1/15)

Life in Solar System
Likely Exists and is More Common Than We Think (Source:
Newsweek)
It’s one of the most compelling questions humanity has tried to answer:
Is there life beyond Earth? Scientists are closer than ever to
answering that question, thanks to a host of technological advances and
each new spacecraft that launches—and sometimes even thanks to evidence
falling right onto our laps.
Evidence like two meteorites that crashed into Earth in 1998. Nestled
within those space rocks were tiny bright blue salt crystals, and
inside of those crystals were tiny pockets of extraterrestrial water
filled with organic compounds, the building blocks of life, according
to new research published on Wednesday.
“I think it’s likely” that there is other life within our solar system,
first author on that work, Queenie Chan, a planetary scientist at Open
University in the U.K., told Newsweek. And even better, she says, we’re
doing the science that might finally find it. “That’s why we like
searching missions, isn’t it?” (1/14)

Why an Old Theory of
Everything Is Gaining New Life (Source: Quanta Magazine)
Twenty-five particles and four forces. That description — the Standard
Model of particle physics — constitutes physicists’ best current
explanation for everything. It’s neat and it’s simple, but no one is
entirely happy with it. What irritates physicists most is that one of
the forces — gravity — sticks out like a sore thumb on a four-fingered
hand. Gravity is different.
Unlike the electromagnetic force and the strong and weak nuclear
forces, gravity is not a quantum theory. This isn’t only aesthetically
unpleasing, it’s also a mathematical headache. We know that particles
have both quantum properties and gravitational fields, so the
gravitational field should have quantum properties like the particles
that cause it. But a theory of quantum gravity has been hard to come by.
physicists have made several other attempts at quantizing gravity in
the hope of finding a theory that would also work when gravity is
strong. String theory, loop quantum gravity, causal dynamical
triangulation and a few others have been aimed toward that goal. So
far, none of these theories has experimental evidence speaking for it.
Each has mathematical pros and cons, and no convergence seems in sight.
But while these approaches were competing for attention, an old rival
has caught up. Click here.
