Artemis-2 mission is now moving towards the moon. At 5:19 a.m. on April 3, a day after launch, the Orion capsule fired the thrusters and left Earth orbit. Now it will travel in space for the next 4 days and reach a place where only 24 humans have been able to reach till date.
This process of firing the engine to leave the Earth’s orbit and go towards the Moon is called ‘translunar injection burn’. This was a maneuver of about 6 minutes, which increased the speed of the vehicle to 22,000 miles per hour i.e., about 34 thousand Km/hr.
On April 1, at 4:05 am, the ‘Space Launch System’ (SLS) took off towards the Moon carrying 4 astronauts aboard the Orion spacecraft.
A slight mistake on the way could cause the spacecraft to collide with the moon.
Artemis-2 is now on ‘free-return trajectory’. This means that the spacecraft is now moving forward based on Newton’s first law of motion – an object that is moving will keep moving. During the entire journey the engines will be fired only for minor repairs. This part is very sensitive. The slightest mistake on the way can cause the spacecraft to collide with the Moon or cause it to wander into infinite space.
Fifth day: Artemis-2 will enter Moon’s gravity
April 5 By the fifth day of the mission, the capsule will slow down due to the pull of Earth’s gravity. But, as soon as it enters the gravitational field of the Moon, its speed will start increasing again and it will start moving rapidly towards the Moon.
Day 6: Moon will appear as big as a basketball
On the sixth day of the mission, Orion will pass just 6,400 km above the lunar surface. During this time, astronauts will be able to see with their own eyes that part of the moon which is never visible from the Earth. When viewed from the window, the moon will appear as big as a basketball held at arm’s length.
- Contact may be lost for 50 minutes:When Orion passes behind the Moon, its contact with Earth may be completely cut off. There will be ‘communication blackout’ for about 50 minutes. Mission Control will not receive signals from the vehicle.
- Will reach this far from Earth for the first time: On this day, Apollo 13’s record of greatest distance from Earth, set in 1970, may also be broken. During this period, the crew of Apollo 13 reached a distance of 400,171.18 km from the Earth. Artemis II is expected to reach a distance of 402336 Km.

Seventh day: The spacecraft will return to Earth due to the gravity of the moon.
On the seventh day, the spacecraft will exit the Moon’s gravitational field and start its journey back towards Earth. Artemis-2’s path is largely similar to that of the Apollo-13 mission of the 1970s.
It will use the Moon’s gravity as a ‘slingshot’, which will push the spacecraft back towards Earth. In the entire mission, the four astronauts will travel about 11.02 lakh Km.
Tenth day: The vehicle will fall in the Pacific Ocean on April 10.
According to the plan, Orion will enter the Earth’s atmosphere on April 11 at 6:30 am Indian time. At 6:36 pm it will ‘splashdown’ in the Pacific Ocean near San Diego. After this there will be a press conference in Houston, in which information about the mission will be given.
