Artemis

After three consecutive cancellations due to technical complications and adverse weather, the unmanned spacecraft 'Orion' has finally started its journey to the moon. The American space research agency NASA plans to send people to the moon again. Its first phase was completed yesterday Wednesday. Mission Launch Director Charlie-Blackwell Thompson celebrated the successful launch at 12:47 PM Bangladesh time by cutting his tie; This is an old NASA practice. NASA's 'mission' to send people to the moon will be completed in 3 phases. The first stage of which is 'Artemis 1'. It is a non-passenger operation. Its main goal is to identify possible 'landing sites' for landing on the moon. The same test will be conducted in the second phase of the mission. If it is successful, man will go to the moon in the third phase of the campaign. After 50 years, NASA has taken initiative to send people to the only satellite of the earth.

Earlier, the launch of 'Artemis 1' has been repeatedly delayed. Last August 29 was the day of this launch. The countdown started at the scheduled time, but had to be stopped midway. A leak in the rocket's liquid hydrogen line was discovered at the last moment. Despite many attempts, the problem could not be resolved. NASA was forced to cancel the mission. The expedition had to be canceled due to mechanical problems. Then September 2 was set as the launch date. That time a leak was found in the liquid hydrogen tank. The campaign was canceled again. In fact, during the launch of 'Artemis 1', 4 large engines under the rocket burn 300,000 liters of super-cold liquid hydrogen and hydrogen to generate enormous power, which propels the rocket into space. Also yesterday, there was a problem with the liquid hydrogen supply line to the core stage of the SLS rocket.

The order to temporarily suspend the launch comes from the control room. At that time, the question arose, will the journey of Artemis One be destroyed again? After solving all the complications, the green signal for the launch came from the NASA control room around 12:30 PM. At 12:47, 40 minutes late, the SLS rocket engines roared.

According to NASA scientists, this is a historic success for them. Earlier in 1969 'Apollo-11' mission sent the first man to the moon. Neil Armstrong and Edwin Aldrin walked on the moon on that NASA mission. In 1972, NASA's Apollo 17 spacecraft landed on the moon with astronaut Jane Cernan. On the half-century anniversary of that event, NASA aims to send astronauts to the moon again.
