A total solar eclipse darkens the sky above the ocean. Several cruise lines are positioning ships in the path of totality for the August 12, 2026, eclipse, with astronauts and other spaceflight experts aboard.
On August 12, the moon’s shadow will sweep across parts of Greenland, Iceland, Spain, Portugal, and the North Atlantic, briefly turning day into night during the first total solar eclipse visible from mainland Europe since 1999. For travelers hoping to see it, one of the best vantage points may be at sea.
Cruise ships have a particular advantage when it comes to eclipse chasing: they can position themselves directly in the path of totality and, depending on conditions, may have some flexibility to adjust their location in search of clearer skies. That has made cruising an increasingly popular way to plan a trip around an eclipse—and this year, dozens of ships will be sailing across the North Atlantic and Mediterranean with the August 12 event built into their itineraries.
Many are bringing eclipse photographers, astronomers, astrophysicists, and other experts aboard to help passengers understand what they’re seeing. But a handful are taking the programming a step further, with former NASA astronauts and other space experts joining the voyage.
