After a couple of delays earlier this year, NASA's Space Launch System finally launched the Artemis II mission, sending four seasoned astronauts on a 10-day journey around the Moon.

Meet the Crew
This mission is led by Commander Reid Wiseman, a US Navy Captain with a remarkable 165 days of experience in space. He's joined by Pilot Victor Glover, who also served in the Navy and made history as the first person of colour to venture beyond low Earth orbit during the SpaceX Crew-1 mission.

Then we have Christina Koch, the Mission Specialist known for holding the record for the longest single spaceflight by a woman—328 days, no less! She'll be making history again as the first woman to fly near the Moon. Rounding out the team is Jeremy Hansen, a Colonel in the Royal Canadian Air Force, marking the first time a non-American has left Earth's orbit to travel towards the Moon. Quite the diverse and capable team!

The Mission Details
As of now, NASA is nearly through the launch sequence, with just a couple of steps left to complete. The next phases include the Apogee Raise Burn and Orion Separation, all of which should be wrapped up within a few hours after liftoff. Once in orbit, the astronauts will spend the first 24 hours testing life-support systems and conducting some proximity operations. If all goes well, they'll perform a Trans-Lunar Injection burn and begin their four-day trip to the Moon.

When they reach the Moon, it's all about the flyby - no landing or orbiting this time. They'll be soaring about 4,700 miles past the Moon's far side, which could make this the furthest humanity has ventured into deep space so far. After the flyby, it's a four-day return to Earth, culminating in a high-speed reentry and splashdown in the Pacific Ocean.

If all goes according to plan, we should see them back around April 10.

The Artemis II mission has yielded some breathtaking visuals, notably the recent total solar eclipse captured from the Orion spacecraft. Astronauts aboard experienced the phenomenon from a vantage point rarely seen, revealing the Moon as a stark black orb encircled by the Sun's luminous halo.



The images taken during this eclipse showcase the Moon's crisp edges and the surrounding stars, creating a mesmerising celestial panorama that seems almost too perfect. NASA shared these stunning photographs, allowing us to witness a unique perspective of the Earth and the Moon during this rare event. One photo echoes the iconic "Earthrise" image from the Apollo 8 mission, depicting Earth partially cloaked in shadow, a moment that resonates deeply with space enthusiasts.

Commander Reid Wiseman described the view as "indescribable," emphasising the surreal nature of witnessing such a phenomenon without atmospheric interference. The eclipse lasted nearly an hour from their location in space, providing a significantly longer experience than what is typically observed from the Earth.

This extraordinary event not only highlights the capabilities of the Artemis program but also reminds us of the awe-inspiring beauty of our universe, encouraging further exploration and appreciation of space.
