The Astrolabe was a French exploration vessel with a notable history rooted in both conversion and scientific discovery. Originally named Coquille, the ship was a horse-transport barge before being transformed into an exploration ship of the French Navy. The vessel's dimensions and specific construction details are not provided, but her design allowed for extensive long-range voyages, including circumnavigations and polar expeditions. She first gained fame during her circumnavigation of the Earth (1822–1825) under the command of Louis-Isidore Duperrey, with Jules Dumont d'Urville serving as second-in-command. During this voyage, she was instrumental in collecting a vast array of biological specimens from regions including the Falkland Islands, Chile, Peru, the Pacific Islands, New Zealand, New Guinea, and Australia. Notable events include her two-week stay in New Zealand’s Bay of Islands in 1824, and her visit to Kosrae, where Duperrey's crew explored the island for ten days. The ship also sailed through the Ellice Islands en route back to France. Renamed Astrolabe in honor of La Pérouse’s ship, she embarked on a second major voyage starting from Toulon on 22 April 1826, aiming to circumnavigate the globe again. During this expedition, Astrolabe explored New Zealand’s coast, where Dumont d'Urville mapped significant landmarks such as d'Urville Island, French Pass, and Torrent Bay. She visited Hobart for repairs in December 1827 and subsequently explored Fiji, the Loyalty Islands, New Guinea, and parts of the Caroline and Molucca islands, contributing to mapping and the collection of archaeological remains of La Pérouse's wreck. In her third voyage (1837–1840), Astrolabe participated in Antarctic exploration aimed at reaching the South Magnetic Pole, an effort motivated by national competition. Under Dumont d'Urville’s command, the ship explored the South Orkney and South Shetland Islands, discovering Terra de Louis-Philippe (Graham Land), and conducting magnetic and geographical surveys. Although the expedition was curtailed due to crew scurvy and weather conditions, the voyage contributed significantly to polar exploration. Several geographical features, including the Astrolabe Glacier, Astrolabe Island, and the Astrolabe Reef, bear her name, highlighting her maritime and scientific significance. Astrolabe’s voyages advanced knowledge of the Pacific, New Zealand, and Antarctic regions, cementing her legacy as a vessel of exploration and scientific inquiry.
