Artemis
Journey to far side of MOON
Artemis II launched on April 1, 2026. It was a crewed flyby mission: launch from Earth, loop around the Moon, and return. It did not land, but it sent humans back to the Moon’s neighborhood for the first time since the Apollo era. Its success raises a bigger question: can humans return to the Moon’s surface by the end of 2028?
The Mission
NASA’s Space Launch System (SLS) rocket lifted off with roughly 8.8 million pounds (about 39 meganewtons) of thrust. It carried the Orion capsule, the crew module that holds the astronauts, on a trajectory that swung around the Moon and back to Earth.

Some pre-flight analyses raised concerns about the capsule’s performance, and the mission’s success shows how valuable real flight data is compared with simulation.
Why the Far Side Matters
The Moon is tidally locked to Earth. It does rotate, but its rotation period matches its orbital period (about 27 days), so the same face always points toward us. The other side, the “far side,” can never be seen from Earth.
- 1968: Apollo 8 astronauts Frank Borman, James Lovell, and William Anders were the first humans to see the far side with their own eyes.
- Today: Robotic probes such as NASA’s Lunar Reconnaissance Orbiter and China’s Chang’e missions have mapped it in detail. Artemis II is the first crewed mission to view it since Apollo 17 in 1972, more than 50 years ago.
The Heat Shield Test
Re-entry is one of the most dangerous phases of any lunar mission. Orion hit Earth’s atmosphere at about 40,000 km/h before splashing down in the Pacific Ocean. Heat shield performance was a key concern after Artemis I, where the shield wore away unexpectedly, and the investigation that followed contributed to schedule delays. Artemis II was the proof that the fix worked with a crew on board.
Can We Reach the Moon by 2028?
Artemis II is a flyby, not a landing. A landing requires further steps: a crewed lander (such as SpaceX’s Starship HLS or Blue Origin’s lander), docking tests, and in-orbit refueling. NASA has been adjusting the schedule and sequence of the Artemis III and IV missions, so the 2028 target depends on how smoothly those pieces come together.
The Role of AI
AI tools are increasingly used in space missions, for example in trajectory analysis, anomaly detection, and managing huge volumes of sensor data. Large language models can help engineers analyze documentation and test scenarios, though they supplement rather than replace physics-based simulation and human expertise.
Beyond the Technology
Artemis is not the end of the story, but the start of a new chapter of Moon missions. Unlike Apollo, which was driven by Cold War competition, Artemis is a multinational effort built around partnerships and the Artemis Accords, a set of principles for peaceful and cooperative exploration. Whether those principles hold up amid today’s political tensions may be as important a question as whether the engineering succeeds.
