SpaceX recovered its Starship upper stage, Ship 40, off Christmas Island in the eastern Indian Ocean on 19 August 2026, after it had floated at sea for about 24 days.
The vehicle had lifted off from Texas on 24 July 2026 and made a controlled splashdown in the Indian Ocean at the end of its flight.
Two large boats towed the roughly 52-metre stage to calmer, shallower water off the island, drawing crowds of onlookers along the coast of the remote Australian territory.
SpaceX engineers are to examine seawater damage and the durability of the heat-shield thermal tiles before any attempt to return the vehicle to Starbase.
Christmas Island is an external territory of Australia about 350 km south of Java and roughly 1,500 km northwest of the Australian mainland.
Christmas Island lies in the eastern Indian Ocean, about 350 km south of Java and Sumatra in Indonesia and roughly 1,500 km northwest of the nearest point on the Australian mainland. It is administered together with the Cocos (Keeling) Islands as the Australian Indian Ocean Territories, the two sharing a single resident Administrator. Its position, far from any continent but close to Indonesian waters, is what made it the nearest sheltered water to a splashdown zone in the open Indian Ocean.
European navigators sight the island.
Captain William Mynors of the British East India Company vessel Royal Mary sails past on Christmas Day and gives the island its name.
Phosphate is discovered on the island.
Britain annexes the island; it is later administered as part of the Straits Settlements and then the Colony of Singapore.
Sovereignty is transferred from the United Kingdom to Australia under the Christmas Island Act 1958.
SpaceX launches Ship 40 from Texas; the stage later splashes down in the Indian Ocean.
After about 24 days adrift, the stage is towed to waters off Christmas Island and recovered.
Christmas Island is not a fragment of a continent. It is the top of a volcano that grew from the deep ocean floor, rising more than 4,500 metres, of which only about 300 to 360 metres stands above the sea. Once such a seamount reaches the surface in warm tropical water, corals colonise its rim. As the volcanic pile slowly subsides and erodes, coral growth keeps pace near sea level and builds a thick limestone cap over the old volcanic rock. Later uplift lifts that limestone platform clear of the water, which is why the island today presents sheer limestone cliffs rising to a central plateau rather than a volcanic cone. The same sequence, volcanic seamount followed by carbonate capping, explains many isolated islands and atolls across the Indian and Pacific Oceans.
Simple Analogy: The volcano built the pillar; the corals put a stone table top on it; later movement of the crust raised the table above the water.
Christmas Island, the Cocos (Keeling) Islands, Diego Garcia and Andaman and Nicobar are the standard set of Indian Ocean island territories in mapping questions.
ISRO's RLV-TD and the Autonomous Landing Mission series address the same reusability goal by a different route.
Isolation produces high endemism; the Christmas Island red crab migration is the textbook example, alongside the Galapagos comparison often made for these reefs.
Like Nauru, Christmas Island was built on phosphate mining and has had to shift to tourism, fishing and services as reserves neared exhaustion.
