A study from National Cheng Kung University in Taiwan found that Artemis II’s April 2026 launch disturbed the ionosphere more than any rocket launch measured so far, Space.com reports.
- Researchers used precise ground GPS networks normally used to track tectonic plates
- Changes in electron density were equivalent to positioning errors of several meters
- Up to 10 times stronger than disturbances after Starship test launches, even though Starship has about twice SLS’s liftoff thrust
The researchers say effects like this could matter for self-driving cars and drone positioning.
My take
Wild that a launch leaves a mark you can measure in GPS. With more heavy launches coming, worth understanding.
God Bless, and May the Source Be with You!
