This Is the Only Color Photo of the First Atomic Explosion
Summary
TLDRAs World War II rages on in the Pacific, American forces face heavy casualties, especially during the intense battle for Iwo Jima. With predictions of immense Allied losses in a possible invasion of Japan, President Truman decides to deploy the atomic bomb. In New Mexico, scientists conduct the first test of a plutonium-fueled bomb, known as 'Fat Man,' at the Trinity site. Despite uncertainties, the test succeeds, marking the dawn of the atomic age. Just 21 days later, the first atomic bomb is dropped on Hiroshima, altering the course of history.
Takeaways
- ⚔️ The war with Japan continues fiercely, with American casualties increasing as they fight across Pacific islands.
- 💥 The battle of Iwo Jima results in some of the bloodiest fighting, with Marines losing more men than the Japanese defenders for the first time.
- ⚠️ U.S. commanders estimate that an invasion of Japan could result in over a million Allied casualties.
- 🛑 President Truman decides to drop an atomic bomb on a Japanese city as soon as one is ready, but it hasn't been completed yet.
- 🌵 The first atomic bomb test is set to take place at a desert site in New Mexico called Trinity, with preparations underway.
- 🔬 Two versions of the atomic bomb exist: Little Boy (destined for Hiroshima) and Fat Man (destined for Nagasaki), with Little Boy using uranium and Fat Man using plutonium.
- ❓ Scientists are unsure about the Fat Man bomb's performance due to the novelty of plutonium, and there's uncertainty about what might happen in the test.
- 🚗 The plutonium core for the Fat Man bomb arrives from Los Alamos just four days before the test, described as warm like a live rabbit.
- ⏱️ On July 16, 1945, at 4:30 a.m., the first atomic bomb test occurs, with observers like scientist Lily Hornig initially doubting its success until witnessing the massive explosion.

Q & A
What was the significance of the American assault on Iwo Jima during World War II?
-The American assault on Iwo Jima was significant because it saw some of the bloodiest fighting of the war. For the first time, the U.S. Marines lost more men killed and wounded than the Japanese defenders, highlighting the fierce resistance of the Japanese forces.
Why did U.S. commanders predict high casualties in the event of an invasion of Japan?
-U.S. commanders predicted high casualties, potentially more than a million Allied troops, due to the intense resistance expected from Japanese forces, based on their refusal to surrender in battles like Iwo Jima.
Why did President Truman decide to use the atomic bomb against Japan?
-President Truman decided to use the atomic bomb because it was seen as a means to quickly end the war with Japan, avoiding the high casualties expected in a ground invasion.
What was the purpose of the atomic bomb test in New Mexico?
-The purpose of the atomic bomb test, conducted at the Trinity site in New Mexico, was to test the plutonium-fueled 'Fat Man' bomb, as scientists were uncertain about its effectiveness due to the newness of plutonium as an element.
What were the two versions of the atomic bomb developed during the Manhattan Project?
-The two versions of the atomic bomb developed were 'Little Boy,' which used uranium and was dropped on Hiroshima, and 'Fat Man,' which used plutonium and was dropped on Nagasaki.
Why was the plutonium-fueled 'Fat Man' bomb considered riskier than the uranium-fueled 'Little Boy'?
-The 'Fat Man' bomb was considered riskier because plutonium was a newly discovered element, and its behavior in a bomb had never been tested, making scientists unsure of its success.
What was the role of Jack Abbey in the Manhattan Project?
-Jack Abbey was a photographer with the Manhattan Project, and he captured the only color photograph of the first atomic explosion during the Trinity test.
What was the atmosphere like among scientists before the Trinity test?
-The atmosphere among scientists was one of uncertainty and nervousness. There were concerns ranging from complete failure to fears that the test might cause catastrophic events, such as igniting the Earth's atmosphere.
What was the significance of the plutonium core arriving at the Trinity site?
-The arrival of the plutonium core at the Trinity site was crucial because it was the key component of the 'Fat Man' bomb, and there was barely enough plutonium in the world to conduct the test. Its arrival marked the final preparation for the historic atomic explosion.
How did scientist Lily Hornig describe her reaction to the atomic explosion during the Trinity test?
-Lily Hornig described the explosion as an incredible sight, with the 'heavens boiling,' and she initially thought the bomb was a dud until it finally detonated just as she was about to leave the area.
Outlines
🌍 Intense Battles in the Pacific Theater
The war with Japan continues to inflict heavy casualties on American forces as they battle across various Pacific islands. The battle for Iwo Jima is particularly brutal, with the Marines suffering higher losses than the Japanese for the first time. Despite the intense fighting, Japanese forces refuse to surrender, leading U.S. commanders to predict that an invasion of Japan could result in over a million Allied casualties.
💣 The Decision to Use the Atomic Bomb
Faced with the staggering potential costs of invading Japan, President Truman decides that an atomic bomb should be used to force Japan's surrender. However, the bomb has not yet been built, and preparations are underway in the New Mexico desert for the first test of an atomic bomb at the Trinity site. Scientists and construction teams work in secrecy to develop the bomb, with anticipation building for the imminent test.
🔬 Testing the Atomic Bomb: Little Boy and Fat Man
Two types of atomic bombs are being developed: Little Boy, which uses uranium and is expected to work without testing, and Fat Man, fueled by plutonium, which requires a test due to the novelty of the element. Plutonium, a newly discovered element, is scarce, and the outcome of the test is uncertain, adding tension as the scientists prepare for the unknown.
🚗 The Plutonium Core Arrives
Just days before the test, the plutonium core for the bomb, no larger than an orange, arrives from Los Alamos, transported in the back seat of an army sedan. A scientist compares its warmth to that of a live rabbit, highlighting the unusual nature of the material. The core's arrival marks a pivotal moment as the final preparations for the test begin.
⏳ Waiting for Detonation
As the time for the test draws near, tensions rise. Scientist Lily Hornig watches from a distant mountaintop, growing increasingly convinced that the bomb will fail to detonate. However, just as she reaches for her car's ignition, the explosion occurs, creating a spectacular sight that defies all expectations. The immense power of the bomb is revealed as the heavens appear to 'boil.'

Photographer Jack Abbey captures the only color photograph of the first atomic explosion at the Trinity test site. The test is a success, and just 21 days later, an atomic bomb will be dropped on Hiroshima, forever altering the course of history.
