Key Takeaways:

A U.S. Air Force C-17 Globemaster III aborted its mission to Antarctica and returned to New Zealand following a Russian warning about a "planned missile launch," which was later clarified as "space-related activity."
New Zealand's Civil Aviation Authority (CAA) was alerted by the Russian Air Traffic Management Centre and subsequently issued a NOTAM (Notice to Airmen) advising of the potential hazard.
The C-17 was on a routine resupply flight for Operation Deep Freeze, an annual U.S. military mission that provides logistical support to the National Science Foundation's U.S. Antarctic Program (USAP).

A spokesperson said Thursday that the agency was alerted to the “potential hazard” by the Russian Air Traffic Management Centre, after which it issued a NOTAM and created a danger area.
