SpaceX's Starship is preparing for flight

After two failed missions, SpaceX will launch its third large-scale Starship rocket on March 14th. Here's everything you need to know about it.
What is a starship?
starship It is the most powerful rocket ever made. Measuring 121 meters long, the reusable booster can lift the second stage to an altitude of more than 70 kilometers before safely landing. This second stage is also reusable and is intended to make Starship an affordable, reliable vehicle that can quickly turn around and start again. The ultimate goal of this project is to land humans on the moon and later on Mars.
What time does Starship take off?
SpaceX announced live stream video The launch will begin at 7:30 a.m. local time in Texas (11:30 a.m. Japan time). The actual launch will take place approximately 30 minutes after the livestream begins.
Where will the starship go?
As you can imagine, this launch is our most ambitious yet. What SpaceX is aiming for Successfully launch the first and second stages, transporting the starship into space, opening and closing the payload door as a test, and finally refueling from one starship to another as a first step. Shuffle from one tank to another. This is essential for long-range missions and reignites the engines for controlled re-entry into Earth's atmosphere.
The launch will follow a new trajectory that will see the second stage splash down in the Indian Ocean. Although designed as a reusable aircraft, the mission is to make slow, controlled landings at sea rather than on land or ships. This is easier and safer at this stage of development.
What happened the last time a starship was launched?
There have been two Starship launches, both of which ended in failure, which is part of SpaceX's “fail fast, learn fast” strategy.
During the first launch on April 20 last year, three of the 33 engines in the first stage failed to ignite. Several more planes subsequently failed in flight. The rocket then went out of control and activated its self-destruct device, leading to what SpaceX sarcastically calls a “rapid unscheduled disassembly (RUD).” The entire flight lasted about three minutes and reached a maximum altitude of 39 kilometers.
Starship's second launch took place on November 18th. This time, all 33 engines fired and the rocket flew far enough for the first and second stages to separate. However, as the first stage decelerated and rotated to begin the landing procedure, it exploded. The second stage continued to fly smoothly until it reached an altitude of about 149 kilometers (149 kilometers), passing the Kármán Line, which marks the beginning of the universe, but it stopped transmitting data before completing its orbit, causing the safety device to fail. I did. Return to Earth.
What if this launch fails?
It probably won't work in some ways. It is highly unlikely that a starship will complete its mission perfectly. However, any failure will provide data and experience that can be used to improve the design and process for the fourth launch. SpaceX has shown in the past that it can iterate quickly and make significant progress with each launch.
