Four astronauts are going near the Moon under NASA’s Artemis-2 mission. He took photographs of the Earth along the way.
As part of NASA’s Artemis-2 mission, four astronauts on their way to the Moon have captured spectacular photographs of the Earth. The earth is looking very beautiful in blue color. In one photo, a curved part of the Earth was visible, while in the other photo, the entire Earth was visible, covered with white clouds.
The four astronauts (3 Americans, 1 Canadian) on the mission have currently reached about 1.8 lakh kilometers away from the Earth. They still have to go 2.4 lakh kilometers more. They will reach the Moon by April 6.
On April 1, at 4:05 am, the ‘Space Launch System’ (SLS) took off towards the Moon carrying 4 astronauts aboard the Orion spacecraft. For the first time since 1972, a human will go close to the moon. However, astronauts will not step on the moon. They will just circle the moon’s orbit and come back.

A day earlier the Orion capsule had left Earth’s orbit
Artemis-2 mission is now moving towards the moon. A day earlier, at 5:19 a.m. Friday, the Orion capsule fired its thrusters and left Earth’s 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/hour.
CSA astronaut Jeremy Hansen and NASA astronauts Reed Wiseman, Christina Koch and Victor Glover spoke from the NeoRian spacecraft.
Next steps of the mission…next 5 days
Fifth day: Artemis-2 will enter Moon’s gravity
By April 5, the fifth day of the mission, the speed of the capsule will slow down due to the pull of Earth’s gravity. 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, Orion will pass just 6,400 km above the moon’s 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 seen from the window, the moon will appear so big, as if a basketball is held near the hand.
Contact may be lost for 50 minutes: When Orion passes behind the Moon, its contact with the 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 400,171.18 km of maximum distance from Earth, set in 1970, may also be broken. Artemis II astronauts are expected to reach a distance of 402,336 km from Earth.
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.
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.

Christina will become the first woman to reach the moon’s orbit: had failed the first time
47-year-old astronaut Christina Koch, who is part of the four-member team of NASA’s Moon Mission Artemis-2, is going to become the first woman in the world to reach the Moon’s orbit. She set the record for the longest solo space voyage (from flight to landing) by a woman by spending 328 days on the International Space Station in 2019-20. The journey to reach this point has not been easy. Read the full news…
