Russian Proton-M Suffers
Failure During Ekspress-AM4R Launch (Source:
NasaSpaceFlight.com)
Russia launched another of their Proton-M rockets on Thursday, with the
mission tasked with lofting the Ekspress-AM4R telecommunications
satellite into orbit. Launch of the Proton-M rocket took place from
Launch Pad 39 at the Baikonur Cosmodrome in Kazakhstan at 21:42 GMT.
However, an unspecified failure was noted during third stage flight.
The rocket and satellite are lost.
The Astrium-built Ekspress-AM4R – which now appears to be lost – was to
provide digital television and radio broadcasting services across
Russia, mobile presidential and government communications, multimedia
services (telephony, video conferencing, data transmission, Internet
access) as well as solutions based on VSAT network technologies.
Itar-Tass says contact with the Proton was lost in 540th second of
flight and nose cone did not separate from the rocket. Here is a list of recent Russian launch failures.(5/15)
What Russia's Anti-NASA
Plan Means for Florida (Source: Orlando Business Journal)
Elon Musk was right when he implied the U.S. may find itself in trouble
if it continued working with Russia regarding its space
industry. What do Russia's new sanctions mean for Central Florida's
space industry, which is still struggling to find its footing after the
space shuttle program came to a close in 2011? It means U.S.-based
commercial space transport is even more important than ever, said Frank
DiBello of Space Florida.
“This type of news even further magnifies the need for the U.S. to be
aggressive about enabling commercial space market expansion ASAP. As
with transport of crews to the ISS, we cannot wait much longer. Swift
action must be taken to ensure our states and commercial U.S. companies
have the tools they need — whether that be dedicated launch
infrastructure or engines — to keep our national space program intact
without reliance on others,” he said.
Expanding commercial space travel in the U.S. would result in more
government contracts — outside of the typical cargo-only deliveries —
and provide much-needed jobs for the region. However, the growth of
that industry has been sluggish due to prolonged discussions on the
future of space travel by officials in Washington and government
budgetary cuts. (5/15)

Florida: Seizing the Lead
in Drones (Source: Orlando Sentinel)
There has been significant buzz around the topic of unmanned aerial
systems (UAS), more commonly known as drones, and the potential for
testing and operating more of these in U.S. airspace in the near
future. On Feb. 14, the FAA announced its intent to develop six UAS
research and test sites around the country. While Florida was not
selected as one of these sites, we moved ahead, providing friendly
airspace and coordination to UAS commercial operators that wish to test
and demonstrate their own capabilities.
Florida provides a multitude of capabilities that make it an ideal
location to support UAS testing. We already have an established, vast
network of controlled airspace; a rich tradition of aerospace expertise
and innovation; simulation and research centers; unique FAA-approved
next-generation systems; a skilled workforce; and a university network
that offers UAS-centered curricula. (5/15)
Report Raises New
Questions About Virgin Galactic (Source: NewSpace Journal)
While Virgin Galactic officials said at public forums in recent weeks
that SS2 powered flights would resume soon, a new report suggests it
may be some time before SS2 returns to the skies, let alone makes it
into space. The Sunday Times reported that SS2′s carrier aircraft,
WhiteKnightTwo (WK2), is grounded because of an issue with the
aircraft’s carbon composite wings. The plane had been undergoing an
annual inspection, as well as a replacement of its landing gear, when
“defects” were found in the wings.
The Times report cited sources that described the defects as “multiple
cracks,” but Virgin Galactic CEO George Whitesides told the paper that
they were “adhesive imperfections” created by extra glue sticking out
where sections of the wing were joined together. But sources describe
them as cracks (not “imperfections”) running along the wing spars. “One
particularly worrisome aspect is that nobody knows why or when they
occurred.”
The Times article also raises a concern about Virgin Galactic's
targeted altitude. A copy of the customer contract states that the
company only guarantees to take people to an altitude of at least 50
miles (80 kilometers) above the Earth. That is below the “Kármán line”
of 100 kilometers that is used as the de facto boundary of space by
many organizations, including the X PRIZE Foundation. It’s also below
what Virgin Galactic officials have publicly said as well, indicating
that SS2 flights would go to at least 100 kilometers. The 50-mile mark,
though, is the boundary used by NASA and the US Air Force in awarding
astronaut wings. (5/15)
Virgin Responds to
Reports About Altitude (Source: NewSpace Journal)
The Sunday Times reported that Virgin was only guaranteeing in its
contracts that it would take people to altitudes of 50 miles (80
kilometers), below the 100-kilometer mark the company had previously
said SS2 flights would achieve. Virgin Galactic CEO George Whitesides
responded to an inquiry about the report by saying 100 kilometers was
still the company’s goal.
“As we have always noted, we will have to prove our numerical
predictions via test flights as we continue through the latter phase of
the test program. Like cars, planes, and every other type of vehicle
designed by humans, we expect our vehicle design and performance to
evolve and improve over time.” (5/15)
Weird Loner Exoplanet
Orbits Far From its Star (Source: Discovery)
An exoplanet that orbits its star at a whopping distance of 2,000 times
the sun-Earth distance — taking 80,000 (Earth) years to complete one
orbit — has been discovered. As far as exoplanets go, that’s the most
extreme orbit found to date. This exo-oddball was found during an
observing campaign seeking out new worlds around a group of young
stars. GU Psc, a star that is roughly a third of the size of our sun,
was recently identified as a member of the AB Doradus group and became
a ripe target for this exoplanetary search. (5/15)

Solar Wind 'Triggers
Lightning on Earth' (Source: BBC)
Activity on the Sun is sparking lightning strikes here on Earth, a
study suggests. Scientists have found that when gusts of high-speed
solar particles enter our atmosphere, the number of lightning bolts
increases. Because solar activity is closely monitored by satellites,
it may now be possible to forecast when these hazardous storms will hit.
The scientists found that when the speed and intensity of the solar
winds increased, so too did the rate of lightning strikes. The team
said the turbulent weather lasted for more than a month after the
particles hit the Earth. Using data from northern Europe, the
researchers found there was an average of 422 lightning strikes in the
40 days after the high-speed solar wind arrived, compared with 321
strikes in the 40 days prior. (5/15)
Air Force Spending $60
Million for SpaceX U.S. Launches (Source: Bloomberg)
The U.S. Air Force is spending about $60 million and using as many as
100 people to certify billionaire Elon Musk’s SpaceX for launching
military and spy satellites, according to the service’s top uniformed
acquisition official. “We’ve got folks busting their butt to get SpaceX
certified despite what everything in the media seems to say,”
Lieutenant General Charles Davis said in an interview.
Davis said the Air Force is eager to find opportunities for SpaceX in
its $67.6 billion launch program as he sought to rebut Musk’s
contention that the service is protecting a monopoly for United Launch
Alliance LLC, a joint venture of Lockheed Martin and Boeing. “We’ve had
to react to SpaceX and members of Congress,” Davis said. “Now there’s
allegations of cronyism; there’s allegations of ‘you just want to give
money to ULA because you don’t want to have a new entrant certified.’”

Committee Questions
Stability of U.S.-Russia Space Partnership (Source: House
Science Committee)
Science, Space, and Technology Committee Chairman Lamar Smith (R-TX),
Space Subcommittee Chairman Steven Palazzo (R-MS) and Space
Subcommittee Vice Chairman Mo Brooks (R-AL) sent a letter to NASA
Administrator Charles Bolden requesting additional information after
press reports highlighted comments by Russia’s Deputy Prime Minister,
Dmitry Rogozin, in which he announced a series of measures in response
to U.S. sanctions.
Specifically, Mr. Rogozin said that Russia intends to reject a U.S.
request to prolong the use of the International Space Station (ISS)
beyond 2020. Mr. Rogozin also suggested that Russia could use the ISS
without the United States. “Our international space partnerships,
including our partnership with Russia, have historically endured
political division,” the Congressmen wrote. “But Deputy Prime Minister
Rogozin’s statements raise serious concerns about the strength of those
partnerships.”
To better understand the potential implications of these comments, the
Congressmen request a briefing from NASA on the current state of
international negotiations related to the proposed extension of the ISS
beyond 2020. They also request a list of all critical components,
services, or capabilities that Russia provides that are necessary for
the continued operation of the ISS beyond 2020. (5/15)

GOP Congressman Wants To
Block Elon Musk From Competing In Space (Source: Forbes)
Supporting the elimination of competition – that notorious creator of
delay and inefficiency – from NASA’s Commercial Crew Program, Robert La
Branche, senior legislative assistant to Rep. John Culberson (R-TX),
uttered these comments to the FAA’s Commercial Space Transportation
Advisory Committee last week: “Paring down the number of competitors
will help things along greatly because the funding won’t be split.”
Of course, what Mr. La Branche and his Congressional boss would really
like to eliminate is that most inconvenient of competitors, the
entrepreneur. And the very worst manifestation of entrepreneurial
pestilence is, of course, California’s notorious Elon Musk. Mr. Musk’s
SpaceX is now threatening to undermine the renowned efficiency of
America’s Military-Industrial-Complex. A series of successful Falcon-9
& Dragon missions have left the traditional vendors looking
overpriced and unambitious.
Musk's competitive approach puts unfair pressure on NASA’s Space Launch
System (SLS), a multi-billion dollar state-owned rework of the space
shuttle that is many years from flying anywhere. What’s a conservative
congressperson to do? While it is surely coincidental that both the SLS
and CST-100 programs are headquartered in Houston, we are lucky to have
Messrs. La Branche and Culberson standing between us and the utter
chaos of free market competition. Click here.

How Badly Can Russia Put
the Squeeze on NASA? (Source: Popular Mechanics)
The Obama Administration wants to play tough with the Russian
government over its invasion of Crimea by imposing sanctions targeting
the assets of key Russian officials. But Russia has struck back by
squeezing the place where it has great leverage over the United
States—the space program. Some of this may be simple posturing.
For one thing, NASA is only in the beginning stages of trying to talk
its international partners into extending the life of the space station
to 2024. "The Russians, frankly, they're not getting as much scientific
return out of the station," says Jeffrey Hoffman, former NASA astronaut
and current MIT professor, "and whether this is something that they
might have done anyway, or they're using this as a way of putting
pressure on NASA, I don't really know." (5/14)

First Competitive EELV
Round Looks like a Two-horse Race (Source: Space News)
SpaceX likely will be the lone challenger to ULA for an initial round
of competitively selected national security launches to be awarded
starting next year, according to an Air Force official. Rocket builder
Orbital Sciences Corp. and propulsion provider ATK Aerospace had said
as recently as 2013 they were interested in launching national security
space payloads and becoming new entrants for the Air Force’s Evolved
Expendable Launch Vehicle program.
But according to Air Force Lt. Gen. Charles Davis, neither Orbital nor
ATK has taken the necessary steps to certify their rockets to carry
national security payloads. That likely means the companies will not be
eligible to compete until the Air Force puts a second round of
satellite launches out for competitive bids in 2018. “So far, as of
yet, while they both expressed interest, neither has actually entered
the certification process,” Davis said. “Neither one of them, if you
will, is anywhere near the position SpaceX is in.” (5/14)
Orbital ATK Have Some
Interesting Decisions Ahead (Source: SPACErePORT)
There was a time when ATK made every effort to avoid competing against
the companies that used its solid rocket motors. ATK's merger with
Orbital Sciences now makes it a major provider of launch services, with
the industry's largest stable of vehicles ranging from small suborbital
rockets up to small- and medium-class orbital launchers, and
potentially a relatively heavy-lift vehicle for human spaceflight and
large government and commercial payloads.
The merger could significantly reduce the cost of current Orbital
rockets that use ATK motors. What remains to be seen is whether
Orbital's Antares will swap its NK-33-powered first stage for an ATK
solid motor, and whether ATK's erstwhile Liberty rocket will ever fly.
Many believe that Liberty is a canceled program, but I have heard that
ATK has only rendered it dormant while NASA prepares its shared-use
launch pad (LC-39B) and figures out whether to use Shuttle-derived
solid rocket motors (the same ones Liberty would use) for the agency's
heavy-lift SLS rocket.
If NASA does go with ATK's solid boosters for SLS, it would help close
the Liberty business case by using the same NASA-supported production
capacity and the same NASA-supported launch pad infrastructure.
SpaceX's aggressive efforts to open up the EELV contract to new
competitors would, if successful, open up a new market for Liberty.

Sagittarius A*: Black
Hole or Wormhole? (Source: Medium)
One of the most extraordinary objects in the Milky Way galaxy is
Sagittarius A* (pronounced Sagittarius A star). This small object is a
bright source of radio waves in the constellation of Sagittarius that
was discovered in 1974. Since then, astronomers have made numerous
observations of Sagittarius A* and the stars nearby, some of which
orbit it at very high velocity. That implies that Sagittarius A* is
extremely massive and since it is so small it must also be hugely dense.
That’s why many astronomers believe this object is a supermassive black
hole lying at the center of the galaxy. But there is another
explanation—that this massive dense object is a wormhole that connects
our region of space to another point in the universe or even to another
part of the multiverse. (Astrophysicists have long known that wormholes
are allowed by the laws of general relativity and may well have formed
soon after the Big Bang.)
If Sagittarius A* is a wormhole, how can astronomers distinguish it
from a black hole? Researchers have now calculated that plasma orbiting
a black hole would look different to the same plasma orbiting a
wormhole. They have calculated the difference and even simulated the
resulting images that should be possible to collect using the next
generation of interferometric telescopes. In other words, if there is a
wormhole at the center of our galaxy, we should be up to see it within
the next few years. (5/14)
