SpaceX starships had many successful test flights. On May 5,2024 (local time in the United States), the latest prototype of its "Starship", the SSN15, successfully completed the high-altitude flight test; In June 2024, the fourth test flight of the starship was successful, and the first-stage thruster successfully landed in the Gulf of Mexico. Not only did it successfully pass through the atmosphere, but it also achieved the first orbital speed controllable landing; In October 2024, the fifth test flight of the starship, the recovery test of the "chopstick clip rocket" was successful; On November 19, 2024, the starship made its sixth test flight. About an hour after launch, it successfully landed in the Indian Ocean. This test flight was not aimed at entering orbit. The super-heavy thruster splashed down in the Gulf of Mexico about seven minutes after launch, and the starship successfully reignited one of the Raptor engines for the first time. In addition, according to NASA's request to the FaA, the seventh test flight of the starship was scheduled to take place on January 11, 2025.

SpaceX's starship rockets had exploded several times during the test. For example, on May 29,2020, the prototype of the Starship spacecraft, SSN4, exploded while testing its engine in Texas, USA. On February 2,2021 (local time), the prototype of the starship, SSN9, exploded on the ground during the test flight. On April 20,2023, the first test flight of the Starship rocket and spacecraft integrated system exploded shortly after lift-off. The rocket engine malfunctioned and the first-stage thruster did not separate from the spacecraft above. On November 18,2023, SpaceX carried out the second test flight of the Starship rocket. Although the first and second stages of the rocket were successfully separated less than three minutes after the launch, the mission control center lost contact with the Starship spacecraft and was forced to activate the self-destruct system. On March 14,2023, the Starship rocket and spacecraft integrated system carried out the third test flight. The second stage of the Starship lost contact during the atmospheric re-entry phase. However, on June 6, 2024, the starship successfully landed in the Indian Ocean. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
On December 9,2020, SpaceX's prototype starship, the SSN8, was tested in Texas, USA. The test flight was about 40,000 feet (about 12,000 meters) high and exploded due to impact when it tried to land six minutes later. The novel "Hundred Years of Spaceship" is equally exciting.

During the sixth test flight of the SpaceX starship, the Raptor engine of the starship ignited during the hot segment separation two minutes after the launch. The super-heavy rocket gently splashed into the Gulf of Mexico instead of recovering as scheduled. Then, the Raptor engine reignited and the starship entered the gliding phase. In addition, there were also cases where starships were in the gliding phase. For example, on March 14, 2024, the starship was in the gliding phase at a speed of 26000Km/H.

According to the conversion formula between breast diameter and diameter, the diameter of the soil ball = 8 - 10 times the breast diameter. Assuming the relationship of 10 times here, when the breast diameter is 50, the diameter is 50×10 = 500. However, according to the conventional understanding, breast diameter was a representation of diameter. A breast diameter of 50 was equivalent to a diameter of 50. Since the reference materials did not specify the conversion relationship under which circumstances, there were these two possible situations. "Life Like a White Birch" is equally exciting.

The diameter at breast height referred to the diameter, which was the diameter of the trunk of the tree 1.3 meters above the ground. "Life Like a White Birch" is equally exciting. Everyone is welcome to click and read it!
The average diameter of the Earth was 12,742.02 kilometers, the diameter of the Earth's equator was 12756 kilometers, and the diameter between the North and South Poles was 12631 kilometers.
The SpaceX spacecraft had a diameter of 9 meters, a height of 50 meters, and a total height of 120 meters (including super-heavy boosters). It was the tallest and heaviest rocket in the world, with a total weight of 5000 tons (including super-heavy boosters weighing 3600 tons and starships weighing 1300 tons). It could send at least 150 tons of payloads into Earth orbit. The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
The diameter of the Earth is 12742 kilometers.
The average diameter of the Earth was about 12,742 kilometers, the diameter of the Earth's equator was about 12,756 kilometers, and the diameter between the North and South Poles was about 12,631 kilometers. Therefore, saying that the diameter of the Earth was about 12,800 kilometers was an approximate statement.
