"On space walk day, you start off with an exercise period on a stationary bicycle while breathing 100% oxygen through a facemask. After that, the task of suiting up begins. You rely on help from an extra crew member who tugs on sleeves, straightens out wrinkles, locks connectors…. It reminds me of a squire in the Middle Ages helping his knight suit up for battle."
"It takes about six hours from the time you start in the morning until you are ready to open the hatch. After all of this preparation, you will not take lightly to a hatch that does not want to open. That’s what happened to us before our spacewalk earlier this year. The hatch dogs were partly released and allowed the hatch to crack open only 3/8th of an inch. A shaft of brilliant sunlight came through the crack, as if teasing us to come out and play."
"Fortunately, experience gained by owning an old pickup truck with cantankerous doors came in handy. With a little jockeying on the handle and some soft-spoken words, the hatch came open and we started our day."
"If we were chasing bad guys, I am afraid they would be well into hyperspace by now."
"In the sci-fi movies, astronauts can quickly do their spacesuits and in short order, be out the door into the vacuum of space. They’re always in a hurry to chase bad guys, alien monsters, or look for holes in the hull spewing out precious atmosphere," ISS science officer Don Pettit.
NASA and other organizations have developed a sophisticated weather monitoring device.
This NASA Global Climate Model (GCM) is used to see how Earth's climate is changing.
A GCM calculates many things, such as how much sunlight is reflected and absorbed by Earth's atmosphere, the temperature of the air and oceans, the distribution of clouds, rainfall, and snow, and what may happen to the polar ice caps in the future.

The Postcard
A postcard that was published by Marken & Bielfeld Inc. of Frederick, Maryland. On the back of the card they have printed:
'Anthodites, Skyline Caverns,
Front Royal, Virginia.
Anthodites - The Orchid of the Mineral
Kingdom - These exquisite flower-like
formations, the rarest calcite formations
known to caverns science, are to be
seen only in Virginia's Skyline Caverns
at Front Royal, Virginia.'
The card was posted in Front Royal on Monday the 8th. May 1950 to:
Mr. & Mrs. Fred H. Lutz,
214, Plymouth Street,
Holbrook,
Massachusetts.
The message on the divided back of the card was as follows:
"Hi!
Nice trip so far.
Am anxious to hear
about your trips.
Love,
Roland, Edna, Jean & Jack."
Skyline Caverns
Skyline Caverns are a series of caves and a tourist attraction located in Warren County, Virginia, one mile (1.6 km) south of Front Royal.
The caverns were discovered by Walter S. Amos, a retired geologist and mineralogist from Winchester, Virginia, on the 17th. December 1937.
Skyline Caverns are open year-round, offering guided tours through the caverns.
History of Skyline Caverns
Walter S. Amos was contracted by several private and government agencies to search for caves and caverns to open in conjunction with Skyline Drive.
During his search, he came across a sinkhole that was located approximately where the parking lot is currently situated.
Normally, sinkholes are created by the collapsing of a cavern roof, which takes the ground above with it. When he saw there was no water in the sinkhole, he believed he had discovered a cavern.
Knowing this, Amos began to search the edges for some opening to the possible cave system below. He found this opening on the lip of the sinkhole by noticing a small colony of camel crickets (which only live in damp, dark areas by nature) under a small ledge.
Upon digging out the first "room" of the caverns, he came into a large system of connected rooms, most of which were navigable and cleared from all obstructions.
Ninety percent of the caverns were naturally accessible and other than the entrance area, only ten percent needed to be dug out. However, the cavern floor was lined with approximately 14 inches (360 mm) of mud and clay, which had to be cleared before the caverns could be opened to the public on April 13, 1939.
The caverns are estimated to be approximately 50 to 60 million years old.
Anthodites
During the clearing of the mud and clay, Amos and his men discovered another area in the caverns that had been blocked for many years. Upon clearing the newly discovered area, the geologist discovered anthodites.
Anthodites are an unusual form of crystal - they are perfect six-sided crystalline structures made of pure calcite. These crystals are now protected by Virginia State Law, and are kept behind closed doors that a tour guide must open for the public to view them.
Skyline Caverns Tours and Other Attractions
Today, guided tours (as opposed to self-guided tours) are given year-round, including on Christmas Day. Tours depart every 15 to 20 minutes, lasting approximately one hour, and cover about 1+1⁄8 miles (1.8 km) of walking, and reaching a depth of 260 feet (79 m) below ground.
Tours cover only about twenty percent of the caverns; the remaining eighty percent is inaccessible to tourists.
Cavern formations visible on the tour include stalactites, stalagmites, columns, "flow-stone", anthodites, and aragonites. Skyline Caverns also features five flowing streams, three of which are visible on the tour.
Additional attractions include a miniature train ride and mirror maze.
Dean Acheson
So what else happened on the day that the card was posted?
Well, on the 8th. May 1950, U.S. Secretary of State Dean Acheson announced an agreement with France and the State of Vietnam to provide ten million dollars of military assistance.
This was the first of what became three billion dollars of American money spent to fight Communism in Indochina over the next 25 years.
Tollund Man
Also on that day, Tollund Man was discovered.
The Tollund Man, who died circa 405–380 BC, is a naturally mummified corpse of a man who lived during the 5th. century BC, during the period characterised in Scandinavia as the Pre-Roman Iron Age.
He was preserved as a bog body, near Silkeborg on the Jutland peninsula in Denmark. The man's physical features were so well preserved that he was initially mistaken for a recent murder victim.
Twelve years before his discovery, another bog body, Elling Woman, was found in the same bog.
The cause of death was by hanging. Scholars believe that the man was a human sacrifice, rather than an executed criminal, because of the arranged position of his body, and his eyes and mouth being closed.
Discovery of Tollund Man
On the 8th. May 1950, peat cutters Viggo and Emil Hojgaard discovered a corpse in the peat layer of the Bjældskovdal peat bog, 12 km (7.5 mi) west of Silkeborg, Denmark, which was so well preserved that they at first believed they had discovered a recent murder victim.
The Tollund Man lay 60 m (200 ft) away from firm ground, buried under 2.5 m (8 ft 2 in) of peat, his body arranged in a foetal position. He wore a pointed skin cap of sheepskin and wool, fastened under his chin by a hide thong, and a smooth hide belt around his waist.
Additionally, a noose made of plaited animal hide was drawn tight around his neck and trailed down his back. Other than these, the body was naked. His hair was cropped so short as to be almost entirely hidden by his cap.
There was short stubble (1 mm (0.039 in) in length) on his chin and upper lip, suggesting that he was usually clean-shaven, but had not shaved on the day of his death. The Tollund Man was approximately 40 years old. The Tollund Man's last meal consisted of a porridge with barley, flax, wild weed seeds, and some fish.
Scientific Examination and Conclusions
Radiocarbon dating of Tollund Man indicated that he died circa 405–380 BC. The preserved tender soft tissues of his body are the consequence of the acid in the peat, along with the lack of oxygen underneath the surface and the cold climate of the Nordic countries.
The acid in the peat is caused by a bryophyte named Sphagnum which fights against degradation due to resistant phenolic compounds contained in its cell walls. Due to the acidity of peat, bones are typically dissolved rather than preserved.
Scientists conducted an isotope analysis to get an accurate idea of where he may have traveled before his death. They took samples from his femur and hair to compare. They were only able to measure up to a year because of his hairs being so short.
The results contained only small differences in strontium isotope proportions, suggesting that he spent his final year in Denmark, and that he may have moved at least 30 kilometres (20 mi) in his last six months.
Examinations and X-rays showed that the man's head was undamaged, and his heart, lungs and liver were well preserved. The Silkeborg Museum estimated his age as approximately 40 years and his height at 1.61 m (5 ft 3 in), a relatively short stature even for the time. It is likely that the body had shrunk in the bog.
On the initial autopsy report in 1950, doctors concluded that Tollund Man died by hanging rather than strangulation. The rope left visible furrows in the skin beneath his chin and at the sides of his neck. There was no mark, however, at the back of the neck where the knot of the noose would have been located.
After a re-examination in 2002, forensic scientists found further evidence to support these initial findings. Although the cervical vertebrae were undamaged (these vertebrae are often damaged as a result of hanging), radiography showed that the tongue was distended - an indication of death by hanging.
The stomach and intestines were examined, and tests carried out on their contents. Scientists identified the man's last meal as porridge or gruel made from grains and seeds, both cultivated and wild. Approximately 40 kinds of seeds were identified, but the porridge was primarily composed of four types: barley, flax, false flax (Camelina sativa), and knotgrass.
From the stage of digestion it was concluded that the man had eaten 12 to 24 hours prior to his death. Because neither meat nor fresh fruit was found in the last meal, it is suggested that the meal was eaten in winter or early spring, when these items were not available.
Both feet and the right thumb, being well conserved by the peat, were also preserved in formalin for later examination. In 1976, the Danish police made a fingerprint analysis, making Tollund Man's thumbprint one of the oldest prints on record.
Display of Tollund Man
The body is displayed at the Silkeborg Museum in Denmark, although only the head is original. Because conservation techniques for organic material were insufficiently advanced in the early 1950's for the entire body to be preserved, the forensic examiners suggested the head be severed and the rest of the body remain unpreserved.
Subsequently, the body was desiccated and the tissue disappeared. In 1987, the Silkeborg Museum reconstructed the body. As displayed today, the original head is attached to a replica of the body.
Other Bog Bodies
In Denmark, more than 500 bog bodies and skeletal remains dating to the Iron Age have been recovered. Specimens from Jutland include the relatively well-preserved Borremose bodies, Huldremose Woman, Grauballe Man on display at Moesgaard Museum near Aarhus, and the similarly conserved Haraldskær Woman.
Approximately 30 of these bog bodies are housed in Danish museums for continued research.

My flickr groups challenge this month was "profession". I have a hard enough time telling people what I do let alone creating a picture of what I do. So I looked around the office and saw a few things that would help illustrate my job. I work in the work of aviation oxygen; both passengers and crew. So here it is, a little pilot along with a passenger oxygen mask. I don't know what else to say about the shot, it was done after a long day of work and could probably be better.
Find great deals on #oxygen_international for #Hyperbaric_Chamber. They offer #safest and #cost-effective monoplace and multiplace hyperbaric chambers for hyperbaric oxygen chamber customers #worldwide. For more information visit tier website.
I've added oxygen to my candy jar. There is a stationery unit and a portable oxygen concentrator that runs about 4 hours on chargeable battery pack. (Inogen one, G3) It can recharge in the car or household power. Next time I see the cardiologist I'll ask if it might change y travel restrictions.

We wear the oxygen mask when the other pilot gets out of his seat.
But, more importantly, this is our lifeline during a depressurization or smoke/fumes/fire.
Hoping to only use as a pre-cautionary measure and never during an emergency....

Oxygen is magnetic!
It is a remarkable chemistry demonstration experiment. You turn on the gas, and a red light emerges. You turn off the gas, and the light disappears. What's going on?
The gas is chlorine (text on gas bottle says "Chlor"). The gas is bubbled through a basic solution of hydrogen peroxide (H2O2+ OH-), and oxygen gas (O2) is produced.
However, this is not ordinary oxygen, but an unstable form. Ordinary oxygen (called triplet oxygen) is magnetic, because two electrons are unpaired. This experiment produces oxygen where all electrons are paired (singlet oxygen) so it is not magnetic (or weakly anti magnetic).
Within microseconds this will change. One of the electrons will change its spin, and the oxygen molecule will be magnetic. This is a more stable situation, and excess energy will be emitted, producing a red light with a wavelength of 634 nm.
The image shows a young Mangrove tree (Avicennia marina) by a South Australian creek at low water with pneumatophores (respiratory roots).
The mud in which the Mangrove grows is waterlogged and therefore oxygen is in short supply. The pneumatophores have lenticels in their bark, which allow oxygen from the air to pass into the root system for respiration.
The young tree is approximately 1 m tall and the pneumatophores up to 50 cm tall.

S83-28321 (14 March 1983) --- In this artist's concept of future lunar operations, a lunar ferry is about to burn out of lunar orbit for the trip back to facilities in low Earth orbit. The ferry vehicle carries tank modules filled with liquid oxygen, which has been produced from mining operations on the surface of the Moon. One possibility for such operations would be to have manned facilities in low lunar orbit, such as illustrated here. At the upper right side of the photo is a small orbiting manned station. At the lower right side of the photo is a liquid oxygen propellant dump, to which a lunar landing vehicle carrying liquid oxygen is about to dock. The lunar ferry vehicle itself is representative of one type of aerobraking system. The balloon-like torus around the center of the ferry-craft would inflate to several times its illustrated size and, once the vehicle has swooped down close to the Earth's outer atmosphere on the return journey, would use atmospheric drag to slow the craft and place itself in low Earth orbit. The liquid oxygen would then be used in operations there for fueling various vehicles, including an orbital transfer vehicle for trips to geosynchronous Earth orbit. This concept is part of a study done for the Johnson Space Center by Eagle Engineering of Houston. The artist was Pat Rawlings.
