Melbourne. Earlier this week, the launch of the Artemis-1 Moon mission was postponed. Now we have to wait for a new launch window. Engineers had to postpone the September 3 launch due to a fuel leak just 40 minutes before the Space Launch System rocket lifted off from Kennedy Space Center in Florida. So what is the launch window after all? And why can’t rockets be launched into space at any time? And what does it mean to “avoid it”? Let’s try to find the answers to all these questions.

A launch window is like waiting for the stars to come within a specific range or location. When the stars are in this position, the rocket is launched from the surface of the earth. The launch of the rocket must be perfectly timed so that the rocket progresses correctly on its prescribed trajectory. And go to the right place at the right time.

Artemis-1 is a mission to send an Orion capsule into orbit around the Moon and the “correct time” for this means that the Moon is as close to Earth as possible during its 28-day cycle (called “perigee”). “). ). So now we have to wait about four weeks for the moon to return to this position.

The direction of flight of any rocket sent into space depends on the gravity of the Earth and the Moon. Since scientists want the Orion capsule to return safely to Earth, its timing is critical. Orion should not collide with the Moon but should pass it safely. Therefore, it is important to know precisely at all times the position of the rocket launcher, the Earth, the Moon and the lunar capsule.

There was a similar story when the James Webb Space Telescope was launched. In this case, mission controllers were making sure it didn’t collide with the Moon on its way to Lagrange Point 2 – the gravitationally balanced gap between Earth and the Sun. The launch of the telescope was modified twice to avoid bad weather. Finally, in 2021, on Christmas Day, the Ariane 5 rocket was launched from French Guiana.

It is certain that the Artemis-1 mission will be launched, but it will be rescheduled at another time. This is good news for anyone who is looking forward to seeing the lunar mission come to an end again for the first time in 50 years. The launch of Artemis-1 has only been postponed until the next available launch window.
