It was launched in the Johnston Island area to an altitude of about 400 kilometers by a Thor rocket and had a yield of 1.4 megatons. The test evaluated the capabilities of an antiballistic missile to operate in a nuclear environment and the vulnerability of a U.S. reentry vehicle to survive a nearby nuclear blast. It also provided information on the ability of a U.S. radar system to detect and track reentry vehicles. Another goal was to discern the effects of a high-altitude blast on command and control systems, which were shown to be vulnerable in earlier high-altitude tests. The final goal was to obtain information on the feasibility of testing in outer space. Fishbowl Auroral Sequences - 7:50 - Color - Silent - BLUEGILL and STARFISH were high-altitude nuclear tests, part of Operation Fishbowl, conducted in the Johnston Island area of the Pacific Proving Ground in 1962. These tests produced auroral effects, a special feature of explosions where the extreme brightness of the fireball is visible at great distances. Within a second or two after the burst, a brilliant aurora appears from the bottom of the fireball. The formation of the aurora is attributed to the motion, along the lines of the earths magnetic field, of beta particles emitted by the radioactive fission fragments. About a minute after the detonation, the aurora could be observed in the Samoan Islands, 2000 miles from the detonation. These auroras could be seen for approximately 20 minutes. The video shows footage of the auroras from Somoa, Mauna Loa (Hawaiian Islands) and Tongtapu (Tonga Islands) at various film speeds. Dominic on Fishbowl Phenomenon - 1:12 - Color - Silent - Operation Fishbowl was the high-altitude testing portion of a larger Operation Dominic I. This video is a compilation of footage of the five nuclear tests comprising Operation Fishbowl conducted in the Johnston Island area of the Pacific Proving Ground in 1962. A high-altitude burst is one occurring above 100,000 feet. The video does not identify the date, time or name of the tests. When a nuclear weapon detonates at a high altitude, many of the effects are attenuated. Most of the x-ray energy is absorbed in the air, which decreases the fireball temperature. Absorption of thermal x-ray energy also decreases the energy available for a shock wave. This all results in the development of a toroidal or donut-shaped cloud instead of the usual mushroom shape of ground or near ground explosions. This also shows the auroral effect of high-altitude explosions where the extreme brightness of the fireball is visible at great distances. Within a second or two after the burst, a brilliant aurora appears from the bottom of the fireball. The formation of the aurora is attributed to the motion, along the lines of the earths magnetic field, of beta particles emitted by the radioactive fission fragments. About a minute after the detonation, the aurora can be observed from as far away as 2000 miles. These auroras can be seen for approximately 20 minutes. Fishbowl XR Summary - 34:38 - Black&amp;White - Silent - The video shows the five, rocket-launched, Operation Fishbowl tests at various camera speeds and from different camera locations. Operation Fishbowl was the Department of Defenses high-altitude testing portion of Operation Dominic I, conducted in the Johnston Island area of the Pacific Proving Ground in 1962. In a high-altitude blast, many of the effects are attenuated, resulting in a toroidal or donut-shaped cloud instead of the mushroom cloud from a surface burst. These weapons-effects tests, launched by Strypi, Thor, and Nike Hercules rockets, were as follows: STARFISH PRIME, July 9, 400-kilometer altitude, 1.4 megaton CHECKMATE, October 20, tens of kilometers altitude, low (less than 20 kt) BLUEGILL 3 PRIME, October 26, tens of kilometers altitude, submegaton (less than 1 Mt, but more than 200 kt) KINGFISH, November 1, tens of kilometers altitude; submegaton (less than 1 Mt, but more than 200 kt) TIGHTROPE, November 4, tens of kilometers altitude, low (less than 20 kt) Two goals of these tests were to determine if radiation and blast and heat effects of high- altitude detonations were capable of neutralizing an enemy reentry vehicle and capable of determining the blackout effects on radar and communications of various yields and altitudes of bursts.\"><\/div><\/div><div class=\"lL\" style=\"max-width:100%;width:480px;margin:5px auto;\"><\/div><figcaption><em>Declassificato US Nuclear Film Test # 62<\/em><\/figcaption><\/figure>\n\n\n<p class=\"wp-block-paragraph\">Ovviamente nello spazio non si produce il classico fungo come quando si fa esplodere sulla Terra in prossimit\u00e0 del suolo. Il fungo viene prodotto dall\u2019aria che produce correnti elevatissime, dapprima espansive e poi di risucchio e in alto una grande nube bianca continua ad allargarsi. Nell\u2019istante in cui avviene l\u2019esplosione si vede solo un enorme lampo accecante pi\u00f9 del sole di \u2019n\u2019 volte ma che \u00e8 in grado di friggere il tuo cellulare a oltre 1000 km di distanza se avviene a 400 km nello spazio.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Non fu l\u2019unico esperimento, ma quando si accorsero che molti aeroporti dovevano bloccare i voli per giorni interi, che si guastavano satelliti in orbita, i pochi che c\u2019erano, e che materiale radioattivo permaneva nella fascia alta dell\u2019atmosfera per anni, hanno capito che forse qualcuno potrebbe essere scontento, quindi, USA e Russia hanno fatto un accordo a livello mondiale per interrompere immediatamente i test. Gli effetti erano di molto superiori al peggiore vento solare mai arrivato sulla Terra.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Erano pi\u00f9 che altro guerre di fuochi artificiali di due paesi che sorgono sui lati opposti dello stesso fiume.

Realizzarono anche progetti definitivi di un vettore a propulsione nucleare i cui test in miniatura con carburante chimico si conclusero positivamente. Lo scopo ufficiale sarebbe stato quello di fare una radiografia della Luna con una botta, dopo aver collocato diversi sismografi.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Poi devono averci pensato perch\u00e9 J.F.K. aveva promesso che sarebbero andati sulla Luna ed era meglio non avere sorprese una volta arrivati l\u00e0.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bibliografia:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/it.wikipedia.org\/wiki\/HANE\" target=\"_blank\" rel=\"noopener\">HANE<\/a><\/strong> (High-Altitude Nuclear Explosions)<br><strong><a href=\"https:\/\/it.wikipedia.org\/wiki\/Starfish_Prime\" target=\"_blank\" rel=\"noopener\">Starfish Prime<\/a><\/strong> (test nucleare ad alta quota)<br><strong><a href=\"https:\/\/en.wikipedia.org\/wiki\/Project_A119\" target=\"_blank\" rel=\"noopener\">Project A119<\/a><\/strong> (noto come &#8220;Studio sui voli di ricerca lunare&#8221;)<br><strong><a href=\"https:\/\/it.wikipedia.org\/wiki\/Atollo_Johnston\" target=\"_blank\" rel=\"noopener\">Atollo Johnston<\/a><\/strong> (\u00e8 un atollo appartenente agli Stati Uniti d&#8217;America a 1300 km dalle Hawaii)<\/p>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-luminous-vivid-orange-color has-alpha-channel-opacity has-luminous-vivid-orange-background-color has-background is-style-wide\"\/>\n\n\n\n<div class=\"wp-block-comments\">\n\n\n\n\n\n\t<div id=\"respond\" class=\"comment-respond wp-block-post-comments-form\">\n\t\t<h3 id=\"reply-title\" class=\"comment-reply-title\"><span id=\"lascia-un-commento-annulla-risposta\">Lascia un commento <small><a rel=\"nofollow\" id=\"cancel-comment-reply-link\" href=\"\/index.php\/wp-json\/wp\/v2\/posts\/7712#respond\" style=\"display:none;\">Annulla risposta<\/a><\/small><\/span><\/h3><p class=\"must-log-in\">Devi essere <a href=\"https:\/\/senzatempo.org\/wp-login.php?redirect_to=https%3A%2F%2Fsenzatempo.org%2Findex.php%2F2019%2F01%2F29%2F7712%2Fcome-si-manifesta-una-esplosione-nello-spazio%2F\">connesso<\/a> per inviare un commento.<\/p>\t<\/div><!-- #respond -->\n\t<\/div>\n","protected":false},"excerpt":{"rendered":"Il cielo nuvoloso di Honolulu di notte a 1300 km dall&#8217;esperimento nucleare nello spazio &#8220;StarFish Prime&#8221;.\n","protected":false},"author":1,"featured_media":7713,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"footnotes":""},"categories":[1915],"tags":[2010,4140,4139,99],"class_list":["post-7712","post","type-post","status-publish","format-standard","has-post-thumbnail","category-armi","tag-armi-nucleari","tag-atollo-johnston","tag-test-nucleare-nello-spazio","tag-usa"],"_links":{"self":[{"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/posts\/7712","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/comments?post=7712"}],"version-history":[{"count":1,"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/posts\/7712\/revisions"}],"predecessor-version":[{"id":7714,"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/posts\/7712\/revisions\/7714"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/media\/7713"}],"wp:attachment":[{"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/media?parent=7712"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/categories?post=7712"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/senzatempo.org\/index.php\/wp-json\/wp\/v2\/tags?post=7712"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
