465.

What significant environmental event was reported in the Arctic in early 2026?

A Record high sea ice extent

B A new record low for winter minimum sea ice extent

C Unprecedented volcanic activity under the ice

D A significant increase in polar bear populations

466.

What are some of the challenges mentioned that need to be overcome for the successful implementation of the mission?
