Study: Artemis II launch linked to 3 ionospheric events over North America, each 5,000+ km

What happened?

1. The researchers say the pulse waves were produced first by the rocket launch and then by upper-stage engines firing in the upper atmosphere.
2. The study team describes the event as a stronger barrage of atmospheric disruption than any previous rocket launch has produced, SpaceX launches included.
3. The study did not directly measure any GNSS or GPS disruption; the team says it hopes to follow up on that question later, TechRadar reports.
4. Charles Lin, the study’s author and an earth scientist working at National Cheng Kung University, stated that a positioning error of a couple of meters suffices to make an autonomous vehicle change lanes.

Researchers studying NASA's Artemis II mission report the strongest launch-induced atmospheric disturbance recorded so far: three ionospheric perturbations over North America, each more than 5,000 km across. The work, set to appear in Geophysical Research Letters, describes the disturbances as human-made 'space weather' produced by the launch and upper-stage engine firings. TechRadar reports the team sees potential for temporary GPS navigation shifts, though the study did not measure them directly.
