There are several effects that would happen.

Here are some of them: 😱

– There would be no mushroom cloud or blast wave 😕, because there is no atmosphere in space to carry the shockwave or the dust.

Instead, there would be a spherical fireball of intense heat and light, expanding rapidly in all directions¹²³.

– The explosion would emit high-energy radiation, such as gamma rays and X-rays, which could damage satellites, spacecraft, and astronauts in orbit. The radiation would also ionize the surrounding gas and create a plasma, which could interfere with radio communication¹²³.

– The explosion would also generate a powerful electromagnetic pulse (EMP), which could induce currents and electric fields in the Earth’s surface and disrupt power grids, electronics, and communication systems. The EMP would also create a temporary artificial radiation belt around the Earth, which could trap charged particles and pose a hazard for satellites and spacecraft¹⁴⁵.

– The explosion would also cause spectacular auroras, or northern and southern lights, to appear in the sky. This is because the charged particles from the explosion would interact with the Earth’s magnetic field and cause it to oscillate. The auroras would be visible for thousands of miles within minutes of the blast, and could last for hours or days¹²³.

These effects have been observed in the past, when the US and the Soviet Union conducted high-altitude nuclear tests in the 1950s and 1960s. The most famous example was the Starfish Prime test in 1962, when the US detonated a 1.4 megaton bomb at an altitude of 250 miles above the Pacific Ocean.

The test caused widespread damage to satellites, disrupted radio communication, and created a dazzling light show in the sky¹²³.

A nuclear explosion in space could have several effects on satellites, GPS, and internet. Here are some of them:

– The high-energy radiation from the blast could damage the electronic components and sensors of satellites, causing them to malfunction or stop working altogether¹²³. This could affect the communication, navigation, surveillance, and scientific functions of satellites.

– The electromagnetic pulse (EMP) from the blast could induce currents and electric fields in the Earth’s surface and disrupt the power grids, electronics, and communication systems that rely on satellites, GPS, and internet¹⁴⁵. This could cause blackouts, data loss, network failures, and service interruptions.

– The plasma and artificial radiation belt created by the blast could interfere with the radio signals that travel between satellites and ground stations, GPS receivers, and internet routers¹²³. This could degrade the quality, accuracy, and availability of satellite, GPS, and internet services.
