LEGO Technic NASA Artemis Space Launch System (42221)

🚀 Explore the future of space exploration with NASA Artemis

The **NASA Artemis Space Launch System Rocket** LEGO® Technic set (ref. 42221) is a fascinating educational project designed for children and space enthusiasts aged 9 and up, allowing them to build and explore the launch system that will take humanity back to the Moon and beyond.

With **632 pieces**, this set, developed in collaboration with NASA and ESA, recreates the epic moment of a rocket launch, showcasing the **3 distinct separation phases** through a functional crank mechanism that allows you to see how each stage decouples during ascent into space.

🌙 Artemis Program: Return to the Moon

NASA's **Artemis Program** is the most ambitious space exploration mission of the 21st century:

Artemis Objectives

• Artemis I - Uncrewed test flight successfully completed in 2022
• Artemis II - First crewed mission around the Moon (planned)
• Artemis III - First human Moon landing since 1972, including the first woman and person of color on the Moon
• Ultimate Goal - Establish sustainable human presence on the Moon as a stepping stone to Mars

Space Launch System (SLS)

The **Space Launch System** is the most powerful rocket ever built by NASA:

• Height of **98 meters** - Taller than the Statue of Liberty
• Payload capacity of **27 metric tons** to lunar orbit
• Thrust of **8.8 million pounds** at liftoff
• Designed to carry the **Orion spacecraft** and its crew beyond low Earth orbit

⚙️ 3-phase separation mechanism

The most educational and impressive feature of the set is its **functional mechanism** that recreates the actual stage separation process:

Phase 1: Solid booster separation

Turn the crank and watch as the **two Solid Rocket Boosters (SRBs)** separate from the core stage. In the real rocket, these boosters provide 75% of the thrust during the first two minutes of flight and then detach when their fuel runs out.

Phase 2: Core stage separation

Continue turning the crank to see the **Core Stage** decouple after it has depleted its fuel. This stage contains the liquid hydrogen and liquid oxygen tanks that power the main engines.

Phase 3: Upper component separation

Keep turning to witness the separation of:

• Upper stage with engine module - Provides the final boost to reach lunar orbit
• Orion spacecraft - Capsule that carries the astronauts
• Launch Abort System (LAS) - Emergency escape tower that detaches when no longer needed

This mechanism is not only fun to operate but also provides a **practical understanding** of how multi-stage rockets work and why stage separation is crucial for reaching space.

👨‍🚀 Four astronaut nanofigures

The set includes **4 astronaut nanofigures** in white spacesuits with the NASA logo:

Crew representation

The nanofigures represent the **four astronauts** who will travel in the Orion capsule during Artemis missions, allowing children to recreate scenes of the crew preparing for launch.

Appropriate scale

The nanofigures are **to scale with the rocket model**, providing a visual reference of the massive size of the SLS compared to humans.

Authentic details

The white spacesuits with the NASA logo add **authenticity** to the model, visually connecting it with real images of the Artemis program.

🔥 Blue flame details

The set includes **blue flame elements** that represent the exhaust from the rocket engines:

Visual realism

The blue flames recreate the **characteristic exhaust** of the RS-25 engines, which burn liquid hydrogen, producing a pale blue flame instead of the typical orange of other fuels.

Launch moment

These elements allow you to **capture the dramatic moment of liftoff**, as the rocket rises from the launchpad in a column of fire and vapor.

📋 Educational information panel

The set includes an **information panel** that provides technical and educational data about the rocket:
