SpaceX 成功發射 Starship 火箭，實現其亟需的復出

SpaceX has achieved a major milestone with its Starship rocket, marking a much-needed comeback after several failed launches earlier this year. The Starship, which is the largest and most powerful rocket ever built, successfully launched from Texas just after 6:30 pm local time. The flight lasted for about an hour and was filled with tense moments, including engine explosions and burning flaps on the rocket's sides. Despite these issues, the rocket managed to reach nearly 200 kilometers above Earth and completed its mission.

Elon Musk, SpaceX's CEO, expressed his excitement and pride in the team, posting 'Great work by the SpaceX team!! ' on social media. Musk has invested billions of dollars into developing Starship, with each launch costing around $100 million. This successful flight is especially important because the previous three launches this year ended in dramatic failures. NASA is relying on Starship for its Artemis program, which aims to send humans to the Moon in 2027.

The Starship rocket consists of two main parts: the Super Heavy booster and the Starship spacecraft. During the test flight, all 33 engines on the booster fired up, and after about seven minutes, the booster separated and fell into the Gulf of Mexico. The Starship continued to ascend, eventually coasting around the planet. SpaceX intentionally pushed the rocket to its limits to test its durability, which led to the flaps burning and swinging wildly during descent. The company hopes that Starship will eventually become a fully reusable transport system capable of carrying people to the Moon and Mars.

Dr. Simeon Barber, a planetary scientist, commented that this was a significant achievement for SpaceX, as they completed the full mission and deployed test satellites. He noted that the data collected from take-off, cruising, and landing would be invaluable for future missions. The first version of Starship had five successful launches, but the latest model had only experienced explosive failures until now. In March, an explosion grounded flights, and in June, another rocket exploded on the launch pad. However, SpaceX did manage to perform the 'chopstick' maneuver, catching the booster with mechanical arms during one test.

NASA has contracted SpaceX to use a modified Starship for its Artemis program, but many experts believe the 2027 target is likely to be delayed. Dr. Barber emphasized that there is still much development needed before Starship can safely carry humans. Musk hopes to have Starship certified for human travel as early as next year and has suggested that un-crewed flights to Mars could begin within 12 months. SpaceX's approach has always been to learn quickly from failures, but after three consecutive failures this year, some questioned the company's future and Musk's focus, especially given his involvement in US politics.

Starship returned to Earth battered but intact, marking a significant step forward for SpaceX. Dr. Ken Kremer, a research scientist, said the program is back on track, but reaching the Moon remains a tough challenge. He believes it is extremely unlikely that the US will land on the Moon in 2027. The US is in a race with China to be the first to return humans to the Moon, but some scientists think China may win, even with Starship's recent progress.
