Tonight, SpaceX Starship spacecraft launches for the fourth time

According to the message released by Elon Musk, the Starship spacecraft - "Super Heavy" booster rocket combination will undergo its fourth test flight tonight, with a potential launch window starting at 20:20 Beijing time and lasting approximately two hours.

On April 20th last year, the Starship first launched into the air, but lost control and exploded in mid-air before separation.

On November 18th last year, the second test was conducted, and the Starship combination successfully completed the hot separation, but the spacecraft subsequently caught fire and exploded, with the rocket also experiencing an engine pressure loss explosion while attempting to adjust its posture for landing.

In the third test flight conducted on March 14th this year, SpaceX successfully advanced the test process to the final stage, but the rocket still lost control while attempting a controlled landing, triggering the breakup procedure.

The fourth test flight will have a trajectory similar to the previous one, with a focus on demonstrating the ability of the Starship spacecraft and "Super Heavy" rocket to return and be reused in a controlled manner.

Currently, the latest development is the loading of propellant into the spacecraft.
