Starship's Flight 4 was a successful test, achieving controlled splashdowns of both the Super Heavy booster and Ship. The mission demonstrated reusability of the massive spacecraft and the Super Heavy booster, with the booster performing a soft landing in the Gulf of Mexico and the Ship surviving reentry and performing a landing burn before splashing down in the Indian Ocean.
During the test, the Starship and Super Heavy booster performed successfully. The Super Heavy booster achieved a soft splashdown in the Gulf of Mexico, while the Starship spacecraft ignited its engines, made a controlled re-entry to Earth, and had a soft splashdown in the Indian Ocean2. The entire flight lasted one hour and six minutes from launch, and the key objective of re-entering Earth was achieved.
Starship re-enters Earth's atmosphere using a combination of stainless steel construction and ceramic tiles for heat resistance. It relies on flaps instead of wings for control during re-entry, allowing for a more stable descent. This innovative approach, while risky, has shown promising results in recent flight tests.
