ionosphere

NASA's SLS rocket, launched for the Artemis II mission, is reported to have punched a hole in the upper atmosphere, disturbing the ionosphere with a measured impact of about 3.7 TECU. Observers note no GPS outages resulted from the disturbance, and the effect was temporary, but the finding has drawn attention to how powerful rocket launches alter the charged particle layer that radio and satellite navigation signals pass through.

NASA's Artemis II mission, the crewed lunar flyby launched in 2026, is associated with reports of ionosphere holes stretching roughly 5,000 kilometres across. Researchers say the rocket's ascent and exhaust plumes can disturb the upper atmosphere, temporarily depleting ionised gas over vast regions. The scale of the disturbance is drawing attention from space weather scientists tracking effects on radio and GPS signals.

NASA's Artemis II moon mission launch reportedly tore a massive hole in Earth's upper atmosphere, large enough to disrupt GPS signals. The SLS rocket's exhaust is said to have disturbed the ionosphere as it blasted toward the Moon, briefly interfering with satellite navigation. The finding is drawing attention for showing how powerful rocket launches can affect technology on the ground.

Artemis II, NASA's crewed lunar mission, is being linked to ionosphere disturbances that produced GPS positioning errors stretching up to 5,000 kilometres. The claim suggests the mission or its launch affected the upper atmosphere in ways that degraded satellite navigation accuracy over a vast area. Details remain sparse, and the scale of the reported errors is drawing attention from space and navigation watchers.

Artemis II, NASA's crewed lunar flyby mission, is drawing attention after measurements showed its launch and ascent produced an ionospheric disturbance of about 3.7 TECU, a sizable total electron content spike in the ionosphere. Despite the disturbance, no GPS outage was recorded, suggesting navigation systems proved more resilient to rocket-induced ionospheric effects than some models predicted. Analysts see the result as useful for planning future lunar missions.

The Artemis II launch generated ionospheric disturbances that produced GPS position errors of several meters, Space.com reports. The powerful rocket's ascent punched through the upper atmosphere, briefly degrading satellite navigation accuracy. Coverage highlights the implications for launch operations and reliance on GPS in regions affected by such disturbances.

Artemis II mission data is being cited showing ionospheric total electron content of 3.7 TECU with zero GPS outages during the flight. The claim suggests the crewed lunar mission maintained continuous GPS-based navigation despite ionospheric conditions, a point of interest for those following deep-space navigation and the mission's technical performance.
