U.S. Coast Guard Cutter Polar Stars crew concludes Operation Deep Freeze 2025 mission, departs Antarctica

The U. S. Coast Guard Cutter Polar Star has successfully wrapped up its Operation Deep Freeze 2025 mission, returning from a 65-day deployment in Antarctic waters. This annual operation, managed by the U. S.

Antarctic Program, is crucial for supporting the National Science Foundation and maintaining international cooperation under the Antarctic Treaty. During its mission, the Polar Star's crew engaged in essential icebreaking duties in McMurdo Sound, ensuring that cargo vessels could safely reach McMurdo Station and Scott Base. Captain Jeff Rasnake remarked on the unexpectedly light ice conditions this year, a stark contrast to the extreme challenges faced during the previous deployment. The operation included a complex array of logistical activities such as airlift support, search and rescue, and bulk fuel supply. These efforts highlight the critical role of the U.

S. Coast Guard in facilitating scientific research and resource management in Antarctica. The successful mission not only showcases the capabilities of the Polar Star but also emphasizes the ongoing commitment to Antarctic research and international collaboration. As the crew heads back to Puget Sound, their work continues to support vital scientific endeavors in one of the world's most remote regions.
