HAARP gave rise to a live album by the rock band Muse and became the theme of novels like La Route de Gakona by Jean-Paul Jody [Wikidata]. [62] HAARP is the key plot point in Breaking Point of Tom Clancy's Net Force (2000), where it is used to induce group madness. [63] The HAARP facility appears in the 2004 video game X-Men Legends.
Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar ...
The ionosphere is where space weather manifests, creating unexpected conditions; electric currents can cause electrical charging of satellites, changing density can affect satellite orbits, and shifting magnetic fields can induce current in power systems, causing strain, disrupting communications and navigation or even triggering blackouts.

The ionosphere bends radio waves in the same manner that water in a pool bends visible light. When the medium through which such waves travel is disturbed, the light image or radio information is distorted and can become unrecognizable. The degree of distortion (scintillation) of a radio wave by the ionosphere depends on the signal frequency.
Here R is the mean Earth radius, H is the mean height of the ionosphere shell. The IPP or Ionospheric Pierce Point is the altitude in the ionosphere where electron density is greatest. [1] These points can change based on factors like time of day, solar activity, and geographical location, which all influence ionospheric conditions. [2]
SpaceX’s rocket explosion in November 2023 created a massive hole in the Earth's ionosphere, providing scientists with a rare opportunity to study its effects.
The ionosphere is a region of the upper atmosphere, from about 80 km (50 miles) to 1000 km (600 miles) in altitude, where neutral air is ionized by solar photons, solar particles, and cosmic rays. When high-frequency signals enter the ionosphere at a low angle they are bent back towards the Earth by the ionized layer. [ 1 ]
The remaining support cables from one tower failed around 7:56 a.m. local time on December 1, 2020, causing the receiver platform to fall into the dish and collapsing the telescope. [ 17 ] [ 25 ] NASA led an extensive failure investigation and reported the findings, [ 26 ] along with a technical bulletin with industry recommendations. [ 27 ]
