One of the few MKT relics along the Clinton branch. This old MKT detector is one of the last few of its kind left in existence.
Two manikins are installed in the passenger seats inside the Artemis I Orion crew module atop the Space Launch System rocket in High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Aug. 8, 2022. As part of the Matroshka AstroRad Radiation Experiment (MARE) investigation, the two female manikins – Helga and Zohar – are equipped with radiation detectors, while Zohar also wears a radiation protection vest, to determine the radiation risk on its way to the Moon. Artemis I will provide a foundation for human deep space exploration and demonstrate NASA’s capability to extend human presence to the Moon and beyond. The primary goal of Artemis I is to thoroughly test the Space Launch System rocket and Orion spacecraft’s integrated systems before crewed missions. Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish sustainable lunar exploration. Photo credit: NASA/Frank Michaux
Hill End is a former gold mining town in New South Wales, Australia. The town is located in the Bathurst Regional Council local Government area New South Wales, Australia. The town is located in the Bathurst Regional Council local Government area..
Hill End owes its existence to the New South Wales gold rush of the 1850s, and at its peak in the early 1870s it had a population estimated at 8,000 served by two newspapers, five banks, eight churches, and twenty-eight pubs..
.
The town's decline when the gold gave out was dramatic: by 1945 the population was 700. At the 2006 census, Hill End had a population of 166 people. The photographer Beaufoy Merlin recorded daily life in the town at its peak; his photographs can be found in the town museum/visitor information centre. The glass plate negatives are held in the State Library of New South Wales..
.
In October 1862 the Telegraph line reached Hill End (Tambaroora) from Bathurst via Sofala, the Telegraph Office opened for telegraph messages bringing the remote town into instant contact with the rest of the Colony. Prior to this event communications took 12 hours by the mail Stagecoach to Bathurst..
.
After delays due to lack of materials a telephone line was installed into Hill End in 1914, after 60 years of Morse code telegraph messages Hill End could now speak to adjacent towns and even Sydney if necessary..
.
In 1923 a telephone exchange was installed at the Hill End Post Office, before this calls could only be made from the Post Office to other towns. The exchange allowed new telephones installed in businesses and private homes to connect locally and to other towns.
.
In the late 1940s Hill End was discovered by artists Russell Drysdale—who painted possibly his best-known work, The cricketers here—and Donald Friend, and quickly became an artists' colony. Other artists who worked there included Jean Bellette. Today, the Hill End artist-in-residence program aims to ensure the continuity of this connection..
.
Hill End is classified as a historical site by the National Parks and Wildlife Service (NPWS), however it is still home to a handful of residents operating the local pub, general store, cake store and antique store. The National Parks and Wildlife Service runs a museum just off the main road which contains many original photos and items of equipment from the busy days of the gold rush. A more extensive museum, the privately owned History Hill, is located a few kilometers from the town on the Bathurst Road..
.
NPWS has installed signs around the town to give visitors an idea of what was once in place on the now empty lots of land. Currently only a handful of buildings remain in their original form. However most of those buildings still serve the purpose they did back during the gold rush. Access to the town's lookouts is via gravel roads. A walking track in the town leads to a mine and other ruins..
.
The most popular tourist activity in Hill End is gold panning, with some of the older members of the community running gold panning tours in the same fossicking areas that yielded the gold which brought on the gold rush. Metal detectors or gold panning are not allowed within the historic site, however there is a fossicking area just past the cemetery, off the Mudgee Road.
ES44AC UP 2546 leads a heterogeneous group of engines, with a Tier 4 GEVO, 2 SD70Ms and an AC44CW, pulling the WP Hauler up the Brooklyn Subdivision to the PNWR yard in Albany, Oregon. This is at one of my usual spots, the Meadowview Road crossing north of Eugene, location of the defect detector at MP 655.5.
This small planetary rover can scan the surface for traces of rare minerals. Inspired by the classic 1980 Mineral Detector set.

A now famous picture from the Hubble Space Telescope featured Pillars of Creation, star forming columns of cold gas and dust light-years long inside M16, the Eagle Nebula. This false-color composite image views the nearby stellar nursery using data from the Herschel Space Observatory's panoramic exploration of interstellar clouds along the plane of our Milky Way galaxy. Herschel's far infrared detectors record the emission from the region's cold dust directly. The famous pillars are included near the center of the scene. While the central group of hot young stars is not apparent at these infrared wavelengths, the stars' radiation and winds carve the shapes within the interstellar clouds. Scattered white spots are denser knots of gas and dust, clumps of material collapsing to form new stars. The Eagle Nebula is some 6,500 light-years distant, an easy target for binoculars or small telescopes in a nebula rich part of the sky toward the split constellation Serpens Cauda (the tail of the snake). via NASA ift.tt/2aApCiB
The end of the day seems like a great time to take the metal detector out.

The question of mass has been especially puzzling, and has left the Higgs boson as the single missing piece of the Standard Model. The Standard Model has three of four of nature's forces: electromagnetism and the strong and weak nuclear forces. Electromagnetism has been fairly well understood for many decades. Recently, physicists have learned much more about the strong force, which binds the elements of atomic nuclei together, and the weak force, which governs radioactivity and hydrogen fusion.
Electromagnetism describes how particles interact with photons, tiny packets of electromagnetic radiation. In a similar way, the weak force describes how two other entities, the W and Z particles, interact with electrons, quarks, neutrinos and others. There is one very important difference between these two interactions: photons have no mass, while the masses of W and Z are huge. In fact, they are some of the most massive particles known.
The first inclination is to assume that W and Z simply exist and interact with other elemental particles. But for mathematical reasons, the giant masses of W and Z raise inconsistencies in the Standard Model. the Higgs boson.

The poles and electrical wires at the very edge of the tracks are part of a falling rock detection system. The regular switching and signal lines are behind the detector up farther on the side of the hill. The power lines an poles are still farther up on the hill. Before this system was installed rocks falling on the railroad line were a real problem. Still a bit of a problem but much better now.
Happy Telegraph Tuesday!
The approaching dawn bruises the sky above the RAF boneyard at Long Marston airfield. This is an English Electric Canberra light bomber, disappearing under a coating of moss and mold.
Night, 2 minute exposure. Full moon (though there was no moonlight filtering through the clouds), strong sodium vapor light, natural flashlight.

This video shows a rather fun little device that can be called an Alpha Spark Detector. I found out about it from Carl Willis and built one of my own a few years ago. And couldn't get it to work.
I drug it out from a dusty corner and worked on it last week. And it sort of worked. And then stopped working. So I rebuilt it. And it sort of worked. So I changed the design. And it sort of worked. And rebuilt it again. Ditto. And finally now.
For such a simple thing there are lots of pitfalls. Dielectric proximity to the spark area causes misfires. Dust, ditto. Electrode wear. As I mentioned in the video reversing the potential stops all function. Huh?
Tips for other builders:
1) Use heavy construction or else the wires will distort the fixture. then your earlier wires will sag as you put in the later wires.
2) 150pF or so is good for the spark visibility. Larger will start to damage the wires. I am using 1Mohm in series with my power supply with the 150pF shunting the two electrodes.
3) Tungsten wire sounds like it might be a good idea to deal with spark erosion. Don't have a clue how to pull it into straight lines and make it stay.
4) The smaller the wire the better it works. I'm guessing that corona ionization from the thinner wires is important.
Cheers.

High technology 1958 style! Great Northern rail detector car R-5 at the Superior roundhouse on July 6, 1958. The rail detectors scanned the steel rails they rode upon testing them for metal fatigue and flaws that if left unchecked could result in broken rails and derailments. These little cars tested rails everywhere on the system on a very regular basis. Later Sperry Rail Service performed the same tasks with an odd assortment of converted gas electric cars. Today the railroads have a combination of private contractors and their own updated rail detector trains that work the system pretty much just like they did in 1958.
Historically speaking, the neat part of this shot is the water tank in the background because the water tub is still intact. The entire tub was removed from the base and retired in June 1962 account (officially) its deteriorated condition. The reality is that without steam locomotives (retired in 1958) the need for this massive 30 foot diameter 100,000 gallon water tank was limited at best. The base for this tank lasted through 1977. If you ever wandered through this facility during the 1970s and saw the base but wondered what happened to the tub, well, now you know.
The GN had a much more modern steel water tank located near 28th Street. That was actually the first one to be retired when the steam engines went away. It's only purpose was to fill steam engine tenders with water. So it was the first to go.
The GN had another wooden tank similar to this one at the roundhouse next to the main lines near Winter Street that was used to water the yard switch engines. With a tank in the yards the switchers didn't need to come back into the roundhouse area for watering. That tank was kept in place to provide water pressure for fire protection throughout the roundhouse, back shops, and mechanical facilities here in Superior. Railroads were very self-sufficient right up until about 1985 when things pretty much went to pot. In this example of self-sufficiency the GN’s water tanks provided both water for thirsty steam locomotives and water for the fire hydrants scattered around the property. The Winter Street tank came down in the mid-1980s. The last shots that I have of it are dated 1982.
