In this photo, we see the nuclear testing at the Bikini Atoll program, which was a series of 23 nuclear devices detonated by the United States between the years 1946 to 1958. Seems a bit scary that it was detonated so close to neighboring islands, but these weapons were tested on the reef itself and in the air.
This all started in July of 1946 with Operation Crossroads, a nuclear weapon test. The island of Bikini Atoll, which is one of the 23 islands that consisted of the Marshall Islands in the Pacific Ocean, was uninhabitable because of all the radiation.
India’s First Satellite
India's first experimental satellite was all solid; it weighed more than 17 tons, was over 20 meters high, and had the ability to place 40 kg of class payloads in LEO ( Low Earth Orbit). It was launched in July of 1980, making India the sixth of the prestige space-faring nation club. This is a rare photo of the satellite, which looks nothing like it would have done today.
The SLV-3 (Satellite Launch Vehicle-3) project paved the way for many future satellite projects, such as the Polar Satellite Launch Vehicle (PSLV) and the Augmented Satellite Launch Vehicle (ASLV), which were both successful.
Testing a Bulletproof Vest
In this photo, we see the testing of a bulletproof vest dated back to 1923. This demonstration was shot live at Washington City police headquarters. The two men in the photo are WH Murphy and his assistant at the Protective Garment Corporation of New York. The vest weighed about 11lb, which was considered comfortable and efficient because it fit perfectly on the body.
Soon after this vest was tested, the Protective Garment Corporation of New York started to manufacture a lightweight vest for the police to use. Of course, these men were inventors and salesmen, and their main goal was to convince the police that their vests worked and that they would save hundreds of lives.
The Gadget
The device seen in this photo is called Trinity. It was the widget used for nuclear testing that was nicknamed The Gadget. This device was considered the first ever Atomic Bomb made to be tested at the Trinity Site in New Mexico on July 16th, 1945, near Alamogordo. It was also the first bomb to be detonated in the Manhattan Project. J. Robert Oppenheimer came up with the code name “Trinity,” which was taken from a line of John Donne's Poetry.
The structure of The Gadget was used again, and it replicated the design of the Fat Man, which was the bomb used during the last days of the Second World War.
Kobe, 1945
The bombing of the Japanese city of Kobe was all part of the strategic campaign that was waged by the United States of America against civilian and military targets. A few months later, during the war, the city was bombed for the second time because it was the sixth-largest area of Japan, with a population of over one million people.
This photo is unique and rare and shows the city of Kobe from a bird's view. The raid that took place on the 16th and 17th of March 1945 was one of the harshest ones in that war, making only the bombing of Hiroshima more tragic and devastating.
