White House Opposes Engine Provisions
in Defense Bill (Source: Space News)
The White House disagrees with the House Armed Services Committee over
how to wean the Defense Department (and ULA) from using Russian-made
RD-180 engines to launch military satellites. Lawmakers also provided
$220 million for a new rocket engine. Air Force officials are wary of
developing an engine that launch companies do not want and instead want
to spend the money more broadly on launch vehicle development.
But in its version of the National Defense Authorization Act for fiscal
year 2016, the committee said the money should go strictly to
development of a “rocket propulsion system, and the necessary
interfaces to the launch vehicle, to replace non-allied space launch
engines.” The White House views this approach as shortsighted.
“While rocket engines are a major component of a launch vehicle, they
are only one of many critical components,” the White House Office of
Management and Budget said in a May 12 statement of administration
policy. “These components must be designed and developed together to
meet the ultimate cost and performance goals, not only for the launch
vehicle but also for the support, operations, and production
infrastructure as well." (5/14)
NSF Should Help Build Massive
Telescope in Hawaii, Says Senior Appropriator (Source: Science)
Representative John Culberson (R–TX) says he’s not butting in. But he
wants the National Science Foundation (NSF) to pay a significant share
of the $1.55 billion cost of a massive telescope to be built in Hawaii.
The Thirty Meter Telescope (TMT) is the dream of a consortium of
universities, foundations, and national observatories in the United
States, Canada, China, India, and Japan. It would be one of the world’s
largest optical telescopes. The consortium has raised between 75% and
80% of what’s needed and has long hoped NSF would be a major backer.
But the agency has yet to commit. In 2013, it gave the TMT consortium a
5-year, $1.25 million grant to study how the agency might participate
in the international project, an effort that could lead to a formal
proposal to the agency in 2017. (5/14)
Is Our Planet Bulking Up on Space Dust
and Meteors? (Source: Arizona Republic)
Although scientists' opinions vary greatly on the amount of meteors and
space dust that land daily on Earth (their estimates are from 5-million
metric tons to 300-million metric tons), other estimates I have heard
are from 20-billion to 80-billion tons a year. Wouldn't you think this
would make the earth become bigger? Click here.

Futuristic Laser Space Engine Passes
Its First Test (Source: Popular Mechanics)
In 2013, Y.K. Bae scored funding from NASA's Innovative Advanced
Concepts program to study an amazing new kind of propulsion: Thrust
that comes not from liquid rockets but from lasers continuously fired
at the spacecraft, which would steadily gain momentum in the
frictionless vacuum of space. It's called the Photonic Laser Thrust
system, and it could drastically reduce the amount of fuel needed for
space missions. And now, Bae has announced that lab tests of the
technology were successful.
In the experiment, Bae fired a laser at a one-pound mock spaceship on a
frictionless track and successfully produced thrust. The laser bounced
continuously between two mirrors inside a cavity at the bottom of the
simulated spaceship, building momentum of 1.1 milliNewtons. (5/14)
Pentagon Says 2013 Chinese Launch May
Have Tested Antisatellite Technology (Source: Space News)
The U.S. Defense Department is suggesting that the May 2013 launch of a
Chinese rocket that it branded at the time as suspicious was a test of
a technology designed to counter or destroy satellites in
geosynchronous orbit. China characterized the launch as a scientific
sounding rocket mission, but the U.S. Air Force said the vehicle’s
trajectory was inconsistent with that explanation. (5/14)
Time to Get Serious About Space Threats
(Source: The Hill)
62 miles above the Earth's surface is the beginning of space. It would
be nice to believe that space is a place of peace and science, but it
is all too clear that at least two of our potential adversaries are
weaponizing space. The United States must take these threats seriously
and respond accordingly in order to defend ourselves and our allies
while deterring potential adversaries from acting irresponsibly in
space.
Both China and Russia have openly admitted that they have or are
developing counter-space capabilities. These capabilities could range
from jamming of GPS signals and satellite communications, to blinding
or damaging our satellites with ground-based lasers, to destroying a
satellite with a missile. China has in fact tested anti-satellite
missiles at least twice in the past two years.
Russia, meanwhile, has launched an undeclared object into space which
our military now believes to be some sort of microsatellite. We do not
know Russia’s intentions, but an object like this could be used to jam
or directly attack our satellites. (5/14)
Government Spending on Space Declines (Source:
Parabolic Arc)
According to Euroconsult’s newly released research report, Profiles of
Government Space Programs, world government expenditures for space
programs decreased by 4% to $66.5 billion in 2014. The decrease in U.S.
military space expenditures combined with the impact of adverse
exchange rates on Russia had a considerable influence on global trends
as the two countries together account for 65% of space expenditures
worldwide. Government spending excluding the U.S. and Russia actually
increased by 8% in 2014. (5/13)

Opponents: Telescope on Haleakala was
Rammed Through by State Leaders (Source: Hawaii News Now)
The $300 million Daniel K. Inouye Solar Telescope on the summit of
Haleakala is halfway completed. It could become Hawaii's third largest
telescope, unless the state's high court decides to halt construction.
Legal experts said that could happen if the Supreme Court sides with
Hawaiian activists, who claimed the project's supporters rammed it
through the permitting process. "Our hands are tied. It's a done deal,"
said the late Kahu Charlie Maxwell in 2010. "I've told them many times
that it shouldn't happen. It's an insult on our culture."
The allegations center on the late Sen. Inouye's staff and University
of Hawaii leaders, who critics say pressured a Land Department hearings
officer. They cited emails describing secret meetings with the Land
Board and its former chief William Aila. The hearings officer called
those meetings improper. (5/13)
Mystery Methane on Mars: The Saga
Continues (Source: Astrobiology)
Is the Red Planet giving off methane? The question has taunted
scientists for nearly 50 years, ever since the Mariner 7 spacecraft
detected a whiff of the gas near Mars’ south pole. Researchers
retracted the finding a month later after realizing that the signal was
in fact coming from carbon dioxide ice.
Then in 2003 and 2004, earthbound telescopes and orbiting spacecraft
rekindled the mystery with reports of large methane clouds in Mars’
atmosphere. Most of Earth’s methane comes from living organisms, though
a small fraction can form when rocks and hot water interact. A burp of
methane on Mars would indicate that the planet might be more alive than
previously thought—whether biologically or geologically. Click here.

Strange Signal from Space May Solve
One of Science's Greatest Mysteries (Source: Space.com)
A clue to one of the biggest questions in cosmology — why regular
matter, rather than antimatter, survived to fill the universe — may
have been found in data from a NASA space telescope.
A new study suggests that gamma-rays (high-energy light) detected by
the Fermi Gamma-ray Space Telescope show signs of the existence of a
magnetic field that originated mere nanoseconds after the Big Bang. In
addition, the researchers on the new study speculate that the magnetic
field carries evidence of the fact that there is far more matter than
antimatter in our universe. (5/14)

Russian Space Cargo Ship Crash Blamed
on Soyuz Rocket (Source: Space.com)
A robotic Russian cargo spacecraft failed to reach the International
Space Station as planned last month because of problems with its
rocket, Russian space officials say. The unmanned Progress 59 space
freighter blasted off atop a Russian Soyuz rocket from Kazakhstan's
Baikonur Cosmodrome on April 28, and was tasked with delivering about 3
tons of food, fuel and other supplies to the orbiting lab.
Now, a preliminary investigation has revealed that Progress 59's issues
stemmed from a too-early separation of the Soyuz's third stage,
officials with Roscosmos, Russia's federal space agency, announced
Tuesday (May 12). This glitch stranded the freighter about 12.4 miles
(20 kilometers) below its target altitude. (5/14)
Private Space Race Tightens in Mojave

Even as Virgin's timeline to fly its first paying customers to
suborbital space has been seriously delayed by the company's fatal
accident last fall, Mojave-based XCOR Aerospace has continued to
develop its own suborbital launch system. Now the company's Lynx Mark I
spacecraft, a horizontal takeoff and horizontal landing vehicle, has
reached another milestone, XCOR said in a news release.
The sleek two-seater is being assembled at XCOR's Hangar 61 at Mojave
Air and Space Port, about 60 miles east of Bakersfield. There,
engineers and technicians have bonded the strakes -- an aerodynamic
surface used to improve the flight characteristics of an aircraft -- to
the plane's fuselage. It's a critical step in development, XCOR
President and Chief Executive Jay Gibson said. (5/13)
