Why 21 Gun Salute …?

The 21-gun salute that we know today has its roots in the ancient tradition of warriors demonstrating their peaceful intentions by resting the point of their weapons on the ground.

The notion of making a soldier’s weapons useless to show that he came in peace continued even as warfare changed over the centuries. Gunpowder and cannons became commonplace among militaries and private forces, both on land and at sea around the 14th century. In order for a ship entering a foreign port to show those on shore that they came in peace, the captain would have his crew fire the guns. This rendered the weapons inoperable for a period of time, with early guns only being capable of firing a single shot before crews needed to reload them.

Traditionally when a British ship entered into a foreign port, it would fire its guns seven times. The reason for the seven shots is widely debated to this day. One theory states that the majority of the British ships at this point only carried seven guns and so firing seven shots became the standard to signal those on shore that the ship was now unarmed. Ships carried enough gunpowder and ammunition to reload multiple times, but beyond symbolism, the idea here was that the lengthy process of reloading would allow the soldiers onshore more than enough time to disable the ship with their own weapons if needs be.

Another proposed theory for the number seven relates to the Bible. After creating the world, the Bible states that God rested on the seventh day (or for the seventh “event”- there is some debate over the “day” vs. “event” translation). So it has been theorized that the number could have been chosen in reference to its Biblical significance, perhaps of resting with the ship coming to port after a long journey. Yet another theory stems from the pervasive superstitious nature of sailors combined with the historic notion in certain regions that the number 7 is sacred, and that odd numbers are lucky and even unlucky. In fact, for a time it was common to use an even number of shots to signify the death of a ship captain when returning from the voyage the death occurred on.

Whatever the underlying reason, the guns onshore would return fire as a form of welcome once the incoming ship finished firing the seven rounds. However, the shore bound guns fired three rounds for every one fired by the incoming ships, putting the total number of shots fired at twenty-one in these cases. As with the “7” number, it’s not known precisely why in the regions that used this number scheme that they chose a 3 to 1 ratio.  What is known is that as time went on where this was practiced, it became traditional for the ships themselves to start firing off 21 shots as well, perhaps due to the ships becoming larger and being equipped with more guns, with the captains ostensibly preferring a 1 to 1 salute.

This then brings us to when firing the 21 shots became considered a type of official salute, rather than a symbolic way to indicate peaceful intentions.  This seems to have started around 1730 when it became a recognized salute to British government officials. Specifically, the British Navy allowed its ships and captains the option to perform the 21-gun salute as a way to honor members of the British Royal Family during select anniversaries. About eighty years later, in 1808, the 21-gun salute officially became the standard salute to honor British Royalty.

While the British Navy adopted the 21-gun salute in 1808 as the standard, other nations, such as the United States, didn’t adopt it until much later. In fact, the United States War Department decided in 1810 to define the “national salute” as having the same number of shots as there were states in the nation. That number grew every year that a new state joined the Union.  Needless to say, this quickly became a cumbersome way to salute the United States and its dignitaries.

That said, the United States did make the “Presidential Salute” a 21-gun salute in 1842, and in 1890 officially accepted the 21-gun salute as the “national salute.” This followed the 1875 British proposal to the United States of a “Gun for Gun Salute” of 21-guns to honor visiting dignitaries.  Essentially, the British and French, among other nations, at this point were all using 21 guns for their salutes, but the U.S. system required many more shots for their dignitaries.  Besides needing to fire off more cannons, this also potentially signified greater honor to the U.S. dignitaries than to those of other nations. Thus, the British proposed a 1 for 1 shot, with 21 being the number, which was accepted by the U.S. on August 18, 1875.

The 21-gun salute still represents a significant honor today. In the United States, the 21-gun salute occurs to honor a President, former president, or the head of foreign state. It can also be fired in order to honor the United States Flag. The salute also occurs at noon on the day of the funeral of a President, former President, or President-elect along with on Memorial Day.

You may have noticed that there’s no mention of the 21-gun salute occurring during military funerals and that’s a common misconception. Known as the “3 Volleys,” the salute that occurs during soldiers’ funerals follows a battlefield tradition where both sides stopped fighting so that they could remove their dead from the field. The series of three shots, or volleys, let the other side know that the dead had been taken care of and that that battle could resume. Therefore the number of volleys is more important than the actual number of shots. Even the United States Army Manuel’s section on the Ceremonial Firing Party at a funeral named the number of riflemen as between five and eight, rather than an exact number.

Sure, the ocean freezes. But this photo of partly frozen waves – caught by photographer and surfer Jonathan Nimerfroh – fascinated even the experts

As you well know if you live there, the eastern United States has been in a deep freeze throughout February, 2015. Wave after wave of ice and snowstorms have hit the region, and NASA says that hundreds (maybe thousands) of records have been set for daily low temperatures. Now, from a photographer and surfer in Nantucket, Jonathan Nimerfroh, we have this amazing photo from February 20, 2015 of an ocean wave, just before it freezes solid. He calls it a slurpee wave.

The New York Times has a great article about this photo and these slow-moving waves of slush. Jonathan’s photo has also been on the Weather Channel and other places (I first saw it on Facebook; thanks, Beverly Spicer!). Nimerfroh told the New York Times:

I just noticed a really bizarre horizon. The snow was up to my knees, getting to the water. I saw these crazy half-frozen waves. Usually on a summer day you can hear the waves crashing, but it was absolutely silent. It was like I had earplugs in my ears.

Of course, the ocean does freeze. Salty sea water has a lower freezing point than the ice in your home freezer, not 32 degrees F but instead about 28.4 degrees F. And it was colder than that on that day in Nantucket, somewhere around 10 degrees F. Still, these waves are something very special, and even experts commented that they had not seen them before. Helen Fricker, a glaciologist at the Scripps Institution of Oceanography in La Jolla, California, who studies the dynamics of ice flows in Antarctica, told the New York Times that a full scientific explanation was “outside her expertise.” Erin Pettit, a glaciologist at the University of Alaska, Fairbanks, added that waves in Alaska tend to break up sea ice and said:

I have never seen frozen waves like this.

Nimerfroh said he returned the following day to the same beach. That day it was a few degrees colder still and the water had completely frozen. He said:

Nothing was moving. There were no waves anymore.

Image For The Day…. Dwarf Planet Ceres as Seen From Dawn Spacecraft Of NASA…

NASA’s Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 38,000 miles (61,000) kilometers from Ceres when it was captured by the dwarf planet’s gravity at about 4:39 a.m. PST (7:39 a.m. EST) Friday, March 6.

This image of Ceres was taken by the Dawn spacecraft on March 1, just a few days before the mission achieved orbit around the previously unexplored world. The image shows Ceres as a crescent, mostly in shadow because the spacecraft’s trajectory put it on a side of Ceres that faces away from the sun until mid-April. When Dawn emerges from Ceres’ dark side, it will deliver ever-sharper images as it spirals to lower orbits around the planet.

The image was obtained at a distance of about 30,000 miles (about 48,000 kilometers) at a sun-Ceres-spacecraft angle, or phase angle, of 123 degrees. Image scale on Ceres is 1.9 miles (2.9 kilometers) per pixel. Ceres has an average diameter of about 590 miles (950 kilometers).

Dawn’s mission is managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, for NASA’s Science Mission Directorate in Washington. Dawn is a project of the directorate’s Discovery Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama. The University of California, Los Angeles, is responsible for overall Dawn mission science. Orbital ATK Inc., in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, the Max Planck Institute for Solar System Research, the Italian Space Agency and the Italian National Astrophysical Institute are international partners on the mission team.

“Harrison Ford is Not Only a Reel Hero… But A Real Hero …” !!!

Harrison Ford showed he takes flying as seriously as acting when he crashed

Officials examine Harrison Ford's vintage airplane on the Penmar Golf Course in Los Angeles, where he crash-landed it on Thursday.

DAMIAN DOVARGANES / THE ASSOCIATED PRESS

Officials examine Harrison Ford’s vintage airplane on the Penmar Golf Course in Los Angeles, where he crash-landed it on Thursday.

Harrison Ford is a hero.

Harrison Fords Jules Verne Award (cropped).JPG

If you said this to his face, of course, he’d scowl. He’d tap his Breitling Aerospace watch and give you 30 seconds to explain. Then you’d back up two steps and nervously recallhis brush with death on Thursday.

“Well, Mr. Ford, when the engine in your Ryan Aeronautical ST3KR conked out after takeoff from Santa Monica Airport, you made an emergency landing on a golf course. You steered away from houses and roadways. You were as cool as Han Solo, as focused as Indiana Jones. Strapped inside that vintage two-seater, you glided to safety without killing yourself or anyone on the ground. Just imagine if . . . ”

“. . . What’s your point?” Ford would cut you off, sounding a bit like his villainous character Dr. Norman Spencer in What Lies Beneath. “I’m no hero. I just take flying very seriously.”

The post-shock reaction to the crash, in which Ford was injured but is expected to fully recover, was predictable. There were stories suggesting the 72-year-old is a real lifedaredevil. There were headlines that wondered if the actor had “the experience to pilot the vintage WWII plane that crashed.”

This is what we do when a celebrity crashes. We theorize, speculate, inculpate, deconstruct and ask pointed questions. The exercise gets foggy and more feverish when those accidents are fatal. In 1997, John Denver was killed after crashing his experimental Rutan Long-EZ plane in Monterey Bay. Two years later, John F. Kennedy Jr., his wife Carolyn Bessette and her sister Lauren died when the Piper Saratoga he was piloting went down in the Atlantic.

We know travelling on a commercial airliner is now safer than at any time since the dawn of powered flight. An MIT study in 2013 concluded a person could fly every day for 123,000 years before getting into a fatal crash. But fear is not rational. And statistics are of cold comfort when we see footage of mishaps, as on Thursday morning when Delta Flight 1086 skidded off an icy runway at LaGuardia Airport.

Meanwhile, Sunday marks a grim anniversary: it has been one year since Malaysia Airlines Flight 370 vanished without a trace.

Accidents happen. Conditions in the sky and on the ground can be unpredictable. Pilots are not immune to error. There can be deadly mechanical failures, especially in aircraft not equipped with the automated systems and safety redundancies and sophisticated navigation computers found in commercial fleets.

Five years ago, a pilot died after his Cessna crashed eerily close to where Ford touched down near the eighth hole at Penmar Golf Course. Santa Monica Airport, where celebrities such as Tom Cruise and Arnold Schwarzenegger keep their planes, has been the point of departure or arrival for at least a dozen crashes since 1989.

So why is Ford a hero? Because during a terrifying few seconds, when everything could have gone terribly wrong, he calmly did everything right. He was flying a plane that was built in the same year he was born.

But as it turns out, Ford is a great pilot for the same reason he’s a great actor: he takes it seriously.

He immerses himself in the process. He masters the small details. He is respectful of the machines he controls and the physical laws he cannot. As he observed in a non-daredevil way in 1998: “Flying attracted me as a chance to develop a skill, build a body of knowledge, not as a way to seek danger. I try to observe a distinction between exciting and scary.”

That distinction has revealed itself in previous close calls.

In 1999, a number of experts were stunned when Ford walked away unscathed after crash-landing his helicopter during a training exercise in California. The next year, he made an emergency landing at Lincoln Municipal Airport in Nebraska due to wind shear. One official who witnessed Ford’s deft handling of the twin-engine Beechcraft Bonanza said: “He’s either very experienced or darn lucky.”

But this isn’t a binary equation. Ford is now both. And that he’s used his love of flying to help others — including rescuing a hiker in Idaho in 2000 and, the following year,finding a missing a Boy Scout in Yellowstone National Park — is proof Hollywood is not just a toxic sinkhole of ego and greed and narcissism.

Hidden behind the fame, lurking behind some of the most memorable characters of our time, stand real heroes.

” MARS once had More Water Than Earth”s Arctic Ocean….”

NASA Research Suggests Mars Once Had More Water than Earth’s Arctic Ocean

Mars once held more water than Earth's Arctic Ocean

NASA scientists have determined that a primitive ocean on Mars held more water than Earth’s Arctic Ocean and that the Red Planet has lost 87 percent of that water to space.

A primitive ocean on Mars held more water than Earth’s Arctic Ocean, according to NASA scientists who, using ground-based observatories, measured water signatures in the Red Planet’s atmosphere.

Scientists have been searching for answers to why this vast water supply left the surface. Details of the observations and computations appear in Thursday’s edition of Science magazine.

“Our study provides a solid estimate of how much water Mars once had, by determining how much water was lost to space,” said Geronimo Villanueva, a scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the new paper. “With this work, we can better understand the history of water on Mars.”

Perhaps about 4.3 billion years ago, Mars would have had enough water to cover its entire surface in a liquid layer about 450 feet (137 meters) deep. More likely, the water would have formed an ocean occupying almost half of Mars’ northern hemisphere, in some regions reaching depths greater than a mile (1.6 kilometers).

The new estimate is based on detailed observations made at the European Southern Observatory’s Very Large Telescope in Chile, and the W.M. Keck Observatory and NASA Infrared Telescope Facility in Hawaii. With these powerful instruments, the researchers distinguished the chemical signatures of two slightly different forms of water in Mars’ atmosphere. One is the familiar H2O. The other is HDO, a naturally occurring variation in which one hydrogen is replaced by a heavier form, called deuterium.

By comparing the ratio of HDO to H2O in water on Mars today and comparing it with the ratio in water trapped in a Mars meteorite dating from about 4.5 billion years ago, scientists can measure the subsequent atmospheric changes and determine how much water has escaped into space.

The team mapped H2O and HDO levels several times over nearly six years, which is equal to approximately three Martian years. The resulting data produced global snapshots of each compound, as well as their ratio. These first-of-their-kind maps reveal regional variations called microclimates and seasonal changes, even though modern Mars is essentially a desert.

The research team was especially interested in regions near Mars’ north and south poles, because the polar ice caps hold the planet’s largest known water reservoir. The water stored there is thought to capture the evolution of Mars’ water during the wet Noachian period, which ended about 3.7 billion years ago, to the present.

From the measurements of atmospheric water in the near-polar region, the researchers determined the enrichment, or relative amounts of the two types of water, in the planet’s permanent ice caps. The enrichment of the ice caps told them how much water Mars must have lost – a volume 6.5 times larger than the volume in the polar caps now. That means the volume of Mars’ early ocean must have been at least 20 million cubic kilometers (5 million cubic miles).

Based on the surface of Mars today, a likely location for this water would be in the Northern Plains, considered a good candidate because of the low-lying ground. An ancient ocean there would have covered 19 percent of the planet’s surface. By comparison, the Atlantic Ocean occupies 17 percent of Earth’s surface.

“With Mars losing that much water, the planet was very likely wet for a longer period of time than was previously thought, suggesting it might have been habitable for longer,” said Michael Mumma, a senior scientist at Goddard and the second author on the paper.

NASA is studying Mars with a host of spacecraft and rovers under the agency’s Mars Exploration Program, including the Opportunity and Curiosity rovers, Odyssey and Mars Reconnaissance Orbiter spacecraft, and the MAVEN orbiter, which arrived at the Red Planet in September 2014 to study the planet’s upper atmosphere.

In 2016, a Mars lander mission called InSight will launch to take a first look into the deep interior of Mars. The agency also is participating in ESA’s (European Space Agency) 2016 and 2018 ExoMars missions, including providing telecommunication radios to ESA’s 2016 orbiter and a critical element of the astrobiology instrument on the 2018 ExoMars rover. NASA’s next rover, heading to Mars in 2020, will carry instruments to conduct unprecedented science and exploration technology investigations on the Red Planet.

NASA’s Mars Exploration Program seeks to characterize and understand Mars as a dynamic system, including its present and past environment, climate cycles, geology and biological potential. In parallel, NASA is developing the human spaceflight capabilities needed for future round-trip missions to Mars in the 2030s.

Look Where This Aircraft Stopped … !!!

A PLANE has skidded off a snowy runway at New York’s LaGuardia Airport​, crashing through a seawall fence​ before stopping just metres from the water’s edge.

None of the 125 passengers and five crew members on board was seriously hurt, but six people suffered minor injuries, sources told The New York Post.

Fuel was leaking from the MD-88 jet and emergency responders were spraying foam to prevent a potential fire after the wing was shorn off.

Sources said Delta Flight 1086 from Atlanta was landing during a snowstorm when it slid off the side of Runway 13 and crashed into a Flushing Bay seawall around 11am Thursday (3am Friday AEDT.

Delta Airlines said in a statement: “Customers deplaned via aircraft slides and have moved to the terminal on buses. Our priority is ensuring our customers and crew members are safe.

“Delta will work with all authorities and stakeholders to look into what happened in this incident.”

Passenger Sam Stern, 64, of Sarasota, Florida, was seated with his wife in an emergency-exit row and had to yank out the window so everyone could escape.

“We came in for landing, the plane hit the ground. As it started to apply the brakes, it started skidding. It didn’t spin around or anything,” he said. “It ended up hitting the embankment. The wing broke off.”

“I’m fine, I hurt my back. Everybody was shaken up, but everyone remained calm and was very caring about everybody else,” he added.

A first responder on the ground was also heard asking if the controller was in touch with the Flight 1086 pilot.

“I’m calling up … no response,” the controller said.

“OK, sir, he is leaking fuel on the left side of his aircraft … heavily. His wing is ruptured,” the responder said.

The incident marked Delta’s first mishap since December 5, 2013, when a 767 returned to land at Madrid-Barajas Airport in Spain after a tire failure at takeoff, according to the Aviation Safety Network.

Image of the Day…. Smallest Full Moon On March 5 2015…

Curtis Beaird in south Georgia captured this shot.

EarthSky Facebook friend Curtis Beaird in south Georgia captured the shot above.

Tonight’s full moon is the smallest full moon of the year. We’ve heard it called the micro-moon or mini-moon. This March 5, 2015 full moon lies about 50,000 kilometers (30,000 miles) farther away from Earth than will the year’s closest full moon – the full supermoon and Northern Hemisphere’s Harvest Moon – on September 28. The March 5 moon is the year’s farthest full moon because full moon and lunar apogee – the moon’s farthest point in its monthly orbit – both fall on the same date.

Every year has a closest full moon, of course. The mini-moon returns about one month and 18 days later with each passing year, meaning that, in 2016, the year’s smallest full moon will come on April 22. In 2017, it’ll come June 9. In 2018, the year’s smallest full moon will come on July 27. And so on, no doubt until our earthly calendars are long forgotten.

By the way, as an aside, mark your calendar for that September 28, 2015 full moon – the Harvest moon – and closest full moon of this year. It’ll also stage a total eclipse of the moon, which some will call a Blood Moon eclipse. It concludes a series of four straight total lunar eclipses that started on April 15, 2014.

The crest of the moon’s full phase comes on March 5, 2015 at precisely 18:05 Universal Time.

Although the full moon occurs at the same instant all around the world, our clocks read differently in different time zones. In the United States, the moon turns exactly full onThursday, March 5, at 1:05 p.m. EST, 12:05 p.m. CST, 11:05 a.m. MST or 10:05 a.m. PST. So the Americas won’t see the moon at the instant it turns full because it happens during the daytime hours, when the moon is below the horizon and under our feet.

The moon looks full for several days around full moon.  William Vann caught this rising almost-full moon on March 4, 2015.

The moon looks full for several days around full moon. William Vann submitted this shot. It’s the rising almost-full moon on March 4, 2015.

No matter where you live worldwide, look for the full moon tonight, lighting up the nighttime from Thursday nightfall until dawn Friday. As with any moon at the vicinity of full moon, tonight’s moon rises in the east at early evening, climbs highest in the sky around midnight and sets in the west in the vicinity of sunrise.

In North America, we often call the March full moon by the names of Sap Moon, Crow Moon, Worm Moon or Lenten Moon. But in recent years, we’ve also heard the term mini-moon to describe the year’s smallest full moon. It’s not a name (like Sap Moon). It’s not bound to a particular month or season. It’s just a term to describe the year’s smallest moon.

What is a mini-moon or micro-moon? Like most astronomers, we at EarthSky have always referred to the year’s smallest full moon as an apogee full moon. The terms mini-moon andmicro-moon stem from popular culture. They roll off the tongue more easily than apogee full moon. As some indication of the appellation’s growing popularity, we’ve found that theNASA Astronomy Photo of the Day and timeanddate.org sites both like to call the smallest full moon a micro-moon.

Billie C. Barb submitted this photo of the rising moon on March 4, 2015 from the state of Washington, saying it was “. . . a love affair between the moon and the evergreens.”

Bottom line: The micro-moon or mini-moon – smallest full moon of 2015 – comes on March 5, 2015 It lies about 50,000 kilometers (30,000 miles) farther away from Earth than will the full moon supermoon of September 28, 2015.
