Army Chief of Staff Orders a Review of EW Shortfalls

mq-1b-predator_009-ts600

Breaking Defense reports that “Army Chief of Staff Mark Milley, has ordered a review of service’s longstanding shortfalls in electronic warfare, officers told me in an exclusive interview. The ultimate goal: give commanders from platoon to corps the ability to shut down enemy radio and radar as readily as they now call in airstrikes and artillery. It’s a critical part of the Army’s plan to hit future enemies from all possible angles at once, a concept called Multi-Domain Battle.”

Col. Mark Dotson noted that an already apparent issue is the problem that the Army’s current plan to rebuild EW “focuses on combat brigades and neglects higher-level formations, like divisions and corps.”

Col. Chris Walls, a cyber/EW expert on the Army staff, notes that the Army wishes to do the same with the invisible artillery of electronic and cyber warfare that it did, since World War II, “when [they had] mortars, artillery, rockets, attack aviation if I had it, all firing at the target at the same time… to force them to face multiple dilemmas simultaneously.”

ATI offers a variety of EW and EW-related courses, some of which are offered at the end of September 2017. These include:

Government Shutdown: U.S. Budget Crisis Looms (Again)

Applied Technology Institute (ATICourses) provides a variety of technical training courses on Space, Satellite, Radar, Defense, Engineering, Systems Engineering, and Sonar.  Now is the time to get your training!

Last government shutdown has occurred in 2013.

 https://en.wikipedia.org/wiki/United_States_federal_government_shutdown_of_2013

We’re months away from the annual budget deadline, and if Congress and President Donald Trump fail to appropriate funds, government departments won’t be able to spend money. This means contractors won’t get paid.

“If the budget debate gets ugly, which is a clear possibility, we could see the shares weaken in September, and then potentially rebound fairly quickly with the conclusion of (or lack of) any shutdown, as was the case in 2013,” Wells Fargo analyst Ed Caso wrote in a Thursday note.

However, those with fixed-price contracts, higher exposure to the Defense or Homeland Security Departments, or more off-site work are considered to be at a lesser risk.

What Could Exactly Happen?

During the federal shutdown of 2013, contractor stocks fell as much as 6 percent, while annual revenue and earnings per share were estimated to average a 1- to 1.5-percent hit, according to Wells Fargo. IFCI also lowered guidance.

But this year’s shocks could be amplified.

“We should note that in 2013 the sector was at through EV/EBITDA (enterprise value to earnings before interest, taxes, depreciation, and amortization) multiples, while now they are in the upper quartile suggesting the potential for more volatility,” Caso wrote.

But How Worried Should We Be?

Given the current political climate, Caso considers a one-day shutdown possible and a multi-day shutdown modestly likely. Still, the caprice of the Trump administration merits preparation.

“The political calculus, in our view, is even more unstable than in 2013, so uncertainty going into GFYend (September) should only be higher even with the memory that no one gained politically from the 2013 shutdown,” he wrote.

Additionally, the drastic budget changes proposed could sustain debate more contentious than that driving the previous 16-day shutdown.

the good fight?

 


10. Carole King
Tapestry (Ode, 1971)

With Tapestry, Carole King cemented her place as one of the key architects of 20th-century popular music. Here, she fully claims the spotlight, not only as a top-notch composer, but as a deeply soulful lyricist and singer.


9. Amy Winehouse
Back To Black (Island, 2006)

The late ’00s saw an explosive, cross-genre revival of retro-sounding soul music that continues to shape the pop landscape to this day. Arguably, that trend’s catalyst was Amy Winehouse‘s earth-shaking final album.


8. Janis Joplin
Pearl (Columbia, 1971)

One of rock’s most misunderstood artists, Janis Joplinwas often portrayed as victim, a dysfunctional mess who only fronted a band, who didn’t have the power to call the shots. Until Pearl. In 1971, with Monterey Pop, Woodstock, and Festival Express behind her, the vision of blues, rock and soul coming together with a band that could follow her was realized. It was her high point, and tragically, she didn’t live to see it. Janis had put the band together — saying “it’s my band, it’s finally my band” — and approved all the songs. (It was unusual at the time for a female artist to actually have that control, the very reason we need this list.)


7. Patti Smith
Horses (Arista, 1975)

The very nature of Patti Smith‘s debut album Horsesrails against what many other “best of” albums are celebrated for — broad appeal, sonically pleasing aesthetics and hits. Horses is confrontational, defiant and completely unafraid of the ugly.


6. Beyoncé
Lemonade (Parkwood/Columbia, 2016)

One of the most recent projects to be part of our new canon, Lemonade is a masterful excursion through terrains at once visually fantastical and emotionally all too real, exploring shattered trust in a broken relationship; the singular pain borne by the mothers of men like Trayvon Martin, Eric Garner and Michael Brown; the battering down of black women throughout history; the scars of all of these kinds of trauma; white-hot rage and hopeful, though not blind, reconciliation.


5. Missy Elliott
Supa Dupa Fly (The Goldmind/Elektra, 1997)

This album dismantled the hip-hop boy’s club. For the first time in history a woman rapped, sang, wrote and produced every song on a major rap release. Within the first sounds that we hear, Missy Elliott invites you to become engulfed with the undeniable Virginia-based funk, a region that’s equally Southern and Eastern, through aquatic synth sounds paired with earthy drum patterns.


4. Aretha Franklin
I Never Loved a Man The Way I Love You (Atlantic, 1967)

In the universe of popular music, this album exploded like a brand new sun. It took Aretha Franklin eleven songs to shift the canon of AM radio away from the realm of girlish glee to the cataclysms of womanly love. I Never Loved a Man connected with black and white audiences and became the biggest commercial success of her building career.


3. Nina Simone
I Put A Spell on You (Philips, 1965)

Nina Simone knew her own power. Not only did she cover the song “I Put A Spell on You,” but she also used it as the title of her autobiography. The song, originally released in 1956 by Jay Hawkins, cemented his “Screamin” moniker. But in Simone’s hands, it became something more, a kind of simmering sorcery.


2. Lauryn Hill
The Miseducation of Lauryn Hill (Ruffhouse/Columbia, 1998)

The Fugees struck gold in the late 1990s with albums like The Score, a feat that also made their resident wordsmith, Lauryn Hill, a household nameBut when Hill went out on her own two years later and dropped her debut, the neo-soul masterpiece The Miseducation of Lauryn Hill, she schooled everyone all over again in new and necessary ways.


1. Joni Mitchell
Blue (Reprise, 1971)

After nearly fifty years, Blue remains the clearest and most animated musical map to the new world that women traced, sometimes invisibly, within their daily lives in the aftermath of the utopian, dream-crushing 1960s. It is a record full of love songs, of sad songs; but more than that, it is a compendium of reasonable demands that too many men in too many women’s lives heard, in 1971, as pipe dreams or outrageous follies.

List of top in count-down order.

GREAT OLD, BIG, HUGE BLACK HOLES

In 1905 Albert Einstein employed one of the most powerful brains on planet Earth to puzzle out an elusive concept called “The Special Theory of Relativity”.  Ten years later he used those same brain cells to develop his even more powerful “General Theory of Relativity”.

Figure 1 highlights his most dramatic proposal for proving – or disproving! – his General Theory of Relativity.  The test he proposed had to take place during a total eclipse of the sun.  For, according to The General Theory of Relativity, light from a more distant star would be bent by about one two-thousandths of a degree when it swept by the edge of the sun.

Four years later (in 1919) the talented British astronomer Arthur Eddington in pursuit of a total eclipse of the sun, ventured to the Crimean Peninsula to perform the test Einstein had proposed based on the idea that “starlight would swerve measurably as it passed through the heavy gravity of the sun, a dimple in the fabric of the universe.”*

A black hole comes into existence when a star converts all of its hydrogen into helium and collapses into a much smaller ball that is so dense nothing can escape from its gravitational pull, not even light.

Capture3

Figure 1:  In 1915, when he finally worked out his General Theory of Relativity, Albert Einstein proposed three clever techniques for testing its validity.  Four years later, in 1919 the British astronomer, Arthur Eddington, took advantage of one of those tests during a total eclipse of the sun to demonstrate that, when a light beam passes near a massive celestial body, it is bent by the local gravitational field as predicted by Einstein’s theory.  This distinctive bending is similar to the manner a baseball headed toward home plate is bent downward by the gravitational pull of the earth.

The existence of black holes was inadvertently predicted by a mathematical relationship Sir Isaac Newton understood and employed in 1687 in developing many of his most powerful scientific predictions, including the rather weird concept of escape velocity.  As Figure 2 indicates, it is called the Vis Viva equation.

Start by solving the Vis Viva equation for the radius Re, then plug in the speed of light, C, as a value for the escape velocity, Ve.  The resulting radius Re is the so-called “event horizon”, which equals the radius at which light cannot escape from an extremely dense sphere of mass, M.  As the calculation on the right-hand side of Figure 2 indicates, if we could somehow compressed the earth down to a radius of 0.35 inches – while preserving its total mass light waves inside the sphere would be unable to escape and, therefore, could not be seen by an observer.  The radius of the event horizon associated with a spherical body of mass, M, is directly proportional to the total mass involved.

Capture4

Figure 2:  The Vis Viva equation was developed and applied repeatedly by Isaac Newton when he was evaluating various gravity-induced phenomena.  Properly applied, the Vis Viva equation predicts that sufficiently dense celestial bodies generate such strong gravitational fields that nothing – not even a beam of light – can escape their clutches.  Today’s astronomers are discovering numerous examples of this counterintuitive effect.  Black holes are one result.

As Figure 3 indicates, an enormous black hole 50 million light years from Earth has been discovered to have a mass equal to 2 billion times the mass of our sun.   It is located in the M87 Galaxy in the constellation Virgo.

Capture5

Figure 3:  In 1994 the Hubble Space Telescope discovered a huge black hole approximately 300,000,000,000,000,000,000,000 miles from planet Earth nestled among the stars of the M87 galaxy in the Virgo constellation.  Astronomers estimate that it is 2,000,000,ooo times heavier than our son.  That black hole’s event horizon has a radius of 3,700,000,000 miles or about 40 astronomical units. One astronomical unit being the distance from the earth to our sun.The graph presented in Figure 4 links the masses of various celestial bodies with their corresponding event horizons.  Notice that both the horizontal and the vertical axes range over 20 orders of magnitude!  In 1942 the Indian-born American astrophysicist, Subrahmanyan Chandrasekhar, demonstrated from theoretical considerations that the smallest black hole that can result from the collapse of a main-sequence star, must have a mass that is equal to approximately 3 suns with a corresponding event horizon of 5.5 miles.  The event horizon of a black hole is the maximum radius from which no light can escape.

DEORBITING SPACE DEBRIS FRAGMENTS USING ONLY EQUIPMENT LOCATED ON THE GROUND

The researchers at NORAD*, which is located under Cheyenne Mountain in Colorado Springs, Colorado, are currently tracking 20,000 objects in space as big as a softball or bigger.  Most of these orbiting objects are space debris fragments that can pose a collision hazard to other orbiting satellites such as the International Space Station.

Tracking these fragments of debris is complicated and expensive.  Preventing collisions is expensive, too.  So, too, is designing and building space vehicles that can withstand high-speed impacts.  A cheaper alternative may be to sweep some of the debris out of space to minimize its hazard to other orbit-crossing satellites.

When two orbiting objects collide with one another, the energy exchange can be large and destructive.  Two one-pound fragments impacting each other in a solid collision in low-altitude orbits intersecting at a 15-degree incidence angle can create the energy caused by exploding two pounds of TNT!!

One scientific study showed that returning substantial numbers of debris fragments to Earth with a hydrogen-fueled spaceborne tug would cost approximately $3 billion for each percent reduction in the fragment population – which has been increasing by about 12 percent per year, on average.

Fortunately, a powerful, but relatively inexpensive laser on the ground pointing vertically upward can be used to deorbit fragments of space debris traveling around the earth in low-altitude orbits.  The radial velocity increment provided by such a ground-based laser causes the object to reenter the earth’s atmosphere as shown in  the sketch in the upper left-hand corner of Figure 1.

The total required velocity increment can be added in much smaller increments a little at a time over days or weeks.  Drag with the atmosphere was neglected in the case considered in Figure 1, but, in the real world, atmospheric drag would help the object return to Earth.

Radiation pressure created by the assumed 50,000 watt laser beam is equivalent to 40 suns spread over the one square foot cross section of the object.  The total photon pressure equals 1/13th of a pound per square foot.

Figure 2:  These engineering calculations show that the 20,000 space debris fragments now circling the earth in low-altitude orbits could, on average, each be deorbited with ground-based lasers for approximately $40,000 worth of electrical power.  Those same ground-based lasers could be used in a different mode to reboost valuable or dangerous payloads in low-altitude orbits or to send those payloads bound for geosynchoronous orbits onto their transfer ellipses.  (SOURCE:  Short course “Fundamentals of Space Exploration”.  Instructor: Tom Logsdon.

AMERICA’S INFRARED SPITZER TELESCOPE by Tom Logsdon

ASA’s Spitzer Space Telescope, which launched Aug. 25, 2003, will begin the “Beyond” phase of its mission on Oct. 1, 2016. Spitzer has been operating beyond the limits that were set for it at the beginning of its mission, and making discoveries in unexpected areas of science, such as exoplanets.

AMERICA’S INFRARED SPITZER TELESCOPE

“As in the soft and sweet eclipse, when soul meets soul on lover’s lips.”

 

British Lyric Poet

                                                                                                Percy Shelly

                                                                                                     Prometheus Unbound, 1820

America’s famous inventor, Thomas Edison, The Wizard of Menlo Park, had long admired the somber, romantic words penned by England’s master poet Percy Shelly.  And, like Shelly, he, too, was enchanted with the sensual experiences conjured up by the periodic eclipses that blotted out the sun and the moon.

In 1878 Edison clambered aboard the newly constructed transcontinental railroad headed from New Jersey to Wyoming where he hoped to utilize his newly constructed infrared sensor to study the total solar eclipse he knew would soon sweep across America’s western landscape.  When he arrived in Wyoming, the only building he could rent was an old chicken coop at the edge of the prairie.  And, as soon as the moon slipped in front of the sun causing the sky to darken, the chickens decided to come to roost.

Soon The Wizard of Menlo Park was so busy trying to quiet his squawking companions, he caught only a fleeting glimpse of the rare and colorful spectacle lighting up the darkened daytime sky.  His infrared sensor, unfortunately, remained untested that day.

Even if those agitated Wyoming chickens had behaved themselves with proper decorum during that unusual event, Thomas Edison’s sensor would have been entirely ineffective because most of the infrared frequencies emanating from the sun and the stars are absorbed by the atmosphere surrounding the earth.  However, sensors of similar design can, and do, handle important astronomical tasks when they are installed in cryogenically cooled telescopes launched into space by powerful and well-designed rockets.

The infrared rays streaming down to earth from distant stars and galaxies lie just beyond the bright red colors at the edge of in the electromagnetic spectrum our eyes can see.  As such, they penetrate the clouds of dust found, in such abundance, in interstellar space.  The dust that has accumulated under your bed is not particularly valuable or interesting.  But the dust found in outer space is far more beneficial – and exciting, too!

The Spitzer Space Telescope – a giant thermos bottle in space – now following along behind planet earth as it circles the sun, was an effective infrared telescope until it used up its entire supply of liquid helium coolant.  In the meantime, it has become a “warm” space-age telescope seeking out previously undiscovered exoplanets orbiting around suns trillions of miles away.  This is accomplished by observing their shadows periodically dimming the star’s visible light as the various planets coast in between the Spitzer and the celestial body being observed.

New Horizons Flyover of Pluto

Two years ago on July 14, 2015, the New Horizon spacecraft reached Pluto. To celebrate this anniversary NASA released a Pluto flyby video.

Using actual New Horizons data and digital elevation models of Pluto and its largest moon Charon, mission scientists have created flyover movies that offer spectacular new perspectives of the many unusual features that were discovered and which have reshaped our views of the Pluto system – from a vantage point even closer than the spacecraft itself.

This dramatic Pluto flyover begins over the highlands to the southwest of the great expanse of nitrogen ice plain informally named Sputnik Planitia. The viewer first passes over the western margin of Sputnik, where it borders the dark, cratered terrain of Cthulhu Macula, with the blocky mountain ranges located within the plains seen on the right. The tour moves north past the rugged and fractured highlands of Voyager Terra and then turns southward over Pioneer Terra — which exhibits deep and wide pits — before concluding over the bladed terrain of Tartarus Dorsa in the far east of the encounter hemisphere.

Digital mapping and rendering were performed by Paul Schenk and John Blackwell of the Lunar and Planetary Institute in Houston.

Background

New Horizons is a space probe launched by NASA on 19 January 2006, to the dwarf planet Pluto and on an escape trajectory from the Sun. It is the first man-made spacecraft to go to Pluto. Its flight took eight years. It arrived at the PlutoCharon system on July 14, 2015. It flew near Pluto and took photographs and measurements while it passed. At about 1 kilobit per second, it took 15 months to transmit them back to Earth.

The New Horizons spacecraft

The primary mission of New Horizons is to study Pluto and its system of moons. The secondary mission is to study any objects in the Kuiper Belt if something became available for a flyby.

The space probe set the record for the fastest man-made object ever launched, with the Earth-relative speed of about 16.26 km/s, although, arguably, the Helios probes got a faster Sun-relative speed. It used a gravity assist from Jupiter to get its high speeds without having to burn as much monopropellant (weak rocket fuel) as needed to fly directly to Pluto.

Russian hacker group ‘CyberBerkut’ returns to public light with allegations against Clinton

CyberBerkutCyberBerkutA Twitter account tied to a group that the Defense Intelligence Agency recently described as “Russian hackers … supporting Russia’s military operations” returned to the spotlight Wednesday by posting a message that alleges Ukrainian government officials and businessmen laundered money and sent it to Hillary Clinton by making donations to the Clinton Foundation.

These allegations, a vague and loosely defined set of financial connections described in a single graphic and related blog post, could not be confirmed. The blog post alludes to an inappropriate relationship between Ukrainian billionaire Victor Pinchuk and the Clinton family. But emails that were supposedly stolen and posted in this blog post do not prove that such a conspiracy occurred. An attempt to contact the group went unanswered.

The Tweet posted Wednesday by this “CyberBerkut” group is the first such message posted publicly since January after the account shared an image of a redacted email it claims revealed plans by the U.S. government to doctor evidence to suggest that Russian hackers had interfered in the 2016 U.S. election.

SpaceX successfully launches third satellite in 12 days

34718447506_7ff2cfa1b2_oRApplied Technology Institute offers a variety of courses on Space, Satellite & Aerospace Engineering.  SpaceX launched a commercial communications satellite using a Falcon 9 rocket, its third flight in just 12 days.

The rocket blasted off on Wednesday evening at 7.38 p.m. (local time) from the Kennedy Space Centre in Florida, delivering the satellite called the Intelsat 35e to a geostationary transfer orbit, reports Xinhua news agency.

The satellite was deployed about 32 minutes after launch.

The California-based company tried to launch the satellite on Sunday and Monday, but stopped twice in the final seconds of countdown.

With a launch mass of over 6.7 tonnes, the Intelsat 35e is the heaviest satellite Falcon 9 has ever sent to orbit.

As a result, SpaceX did not attempt to recover the rocket’s first stage after launch this time, the company said.

It was lofted to provide high-performance services in both the C- and Ku-bands. Wednesday’s mission came just 10 days after SpaceX’s first-ever “doubleheader” weekend, when it launched two missions within about 50 hours.

One saw the launch of BulgariaSat-1, the first geostationary communications satellite in Bulgaria’s history, from the Kennedy Space Centre on June 23.

Another had 10 satellites launched to low-Earth orbit for the U.S. satellite phone company Iridium from the Vandenberg Air Force Base in California two days later.

The Intelsat 35e also marked the tenth of SpaceX’s more than 20 launches planned this year. Last year, the company completed eight successful launches before an explosion during routine ground testing temporarily halted Falcon 9 launches.

Meanwhile, while the Intelsat 35e mission involved an expendable Falcon 9 first stage, SpaceX has recovered 11 first stages on previous missions, re-flying and re-landing two of them. The company has also started tackling the challenge of recovering and reusing the launch vehicle’s payload fairings.
