As NASA’s Artemis II mission prepares on the launch pad, humanity’s return to the moon for the first time since 1972 is just around the corner.
The mission features four astronauts: NASA commander Reed Wiseman, pilot Victor Glover, mission specialist Christina Koch, and Canadian Space Agency’s Jeremy Hansen. They will orbit the moon for 10 days before returning safely to Earth.
Launched in 2017, the Artemis mission aims to return humans to the moon, including the first woman and the first person of color.

If successful, the next mission, Artemis III, aims to land two astronauts on the moon as early as 2028.
The Artemis II launch window is set from April 1st to April 6th. While you await the launch, explore these 22 astonishing facts about Artemis II.
1. Unique Historical Artifacts Will Accompany the Mission
Artemis II will carry a 1-inch square of fabric from the Wright Brothers’ first powered flight in 1903, and the American flag flown during both the inaugural and final Space Shuttle missions, as well as during the first crewed Crew Dragon test.
A flag intended for the cancelled Apollo 18 mission will finally visit the moon after half a century. Additionally, memory cards with millions of names will also be part of this mission.
2. Artemis II Is Almost as Tall as Big Ben
Standing at 98 meters (322 feet), NASA’s Space Launch System (SLS) rocket surpasses Big Ben by 2 meters (7 feet). When fully fueled, the rocket weighs 2,600 tons (5.76 million pounds), but Big Ben is estimated to weigh around 13,700 tons (30 million pounds).
3. The Crew Will Travel Farther than Any Humans Before
Artemis II’s flight path will reach approximately 402,000 km (250,000 miles) from Earth, breaking the Apollo 13 record of 400,171 km (248,655 miles). The total distance traveled will exceed 1 million kilometers (620,000 miles), equivalent to driving across the U.S. coast-to-coast over 200 times.
4. Fastest Return for Astronauts in 50 Years
Upon re-entry, the crew will reach speeds of around 40,000 km/h (25,000 mph), potentially breaking the Apollo 10 record of 39,938 km/h (24,816 mph).
5. Crew Will Experience Life in Limited Space
The four-person crew will utilize the Orion multipurpose crew vehicle where they will work, eat, and rest in a compact area. A designated “hygiene bay” offers some privacy.
6. No More Drinking Recycled Urine
While on the ISS, astronauts recycle urine, but on Artemis II, the crew will dispose of urine in space. Solid waste will be stored for disposal upon return.
7. Rockets Consume a Massive Amount of Fuel
The SLS’s solid booster rockets burn six tons of propellant every second, producing more thrust than 14 jumbo jets. The core stage will consume 2.8 million liters (733,000 gallons) of liquid hydrogen and oxygen.
In total, the rocket generates 8.8 million pounds of thrust in the eight minutes required to reach orbit.
8. Intense Heat During Reentry
As the spacecraft enters Earth’s atmosphere, temperatures outside will soar to around 2,750°C (5,000°F), about half the sun’s surface temperature. The heat shield will protect the crew and maintain a comfortable cabin temperature.
9. None of the Crew Were Alive During the Last Moon Landing
The oldest crew member, Reed Wiseman, was born in 1975, three years after Eugene Cernan’s final Apollo 17 moonwalk.
10. Rocket Engines Have Historic Roots
NAVY reused the shuttle engines in SLS’s orange core stage, ensuring cost-effectiveness with various components dating back to the first Space Shuttle mission in 1981.
11. First Non-American Astronaut to Travel to the Moon
Although selected as a Canadian astronaut in 2009, this will be Jeremy Hansen’s first space mission, following 17 years of training and practice.
12. First Glimpses of Unseen Moon Areas
The crew will explore the far side of the moon and the south pole, locations never witnessed by humans before.
The moon will seem like a basketball at arm’s length and can be surveyed in just three hours.
13. Christina Koch: First Woman on the Moon
With 328 days in space, Christina Koch, the most experienced crew member, will break barriers as she becomes the first woman to approach the moon.
14. Free Return Orbit Similar to Apollo 13
After two days in orbit, Artemis II will execute a “free return orbit,” utilizing lunar and Earth gravity to return home, a crucial strategy that saved Apollo 13.
15. Crew Practices “Parking” Maneuvers in Space
Once separated from the final rocket stage, the Orion module will conduct an automatic backflip, allowing the crew to practice maneuvering close to their target for future docking.
16. Pilot Victor Glover: A Historic First
Victor Glover, a seasoned pilot and former test pilot, will become the first person of color to travel to the moon, continuing to make history on his missions.
17. Modern Space Cuisine
Crew members enjoy a diverse menu on Artemis II, including chicken curry and shrimp cocktail, all designed to avoid crumbs that could disrupt sensitive equipment.
18. Reed Wiseman: An Experienced Photographer of Earth
During his 165 days on the ISS, Wiseman captured thousands of stunning images of Earth, and he will have the opportunity to photograph the moon in detail.
19. High-Speed Laser Communications
Artemis II will feature an advanced optical communication system using lasers, significantly enhancing data transmission speeds, crucial for future deep space missions like Mars.
20. Gym Equipment on the Moon
To combat muscle and bone atrophy in microgravity, astronauts will utilize an exercise “flywheel” daily, offering resistance for effective workouts.
21. Radiation Challenges Ahead
Beyond Earth’s magnetic field, Artemis II faces radiation challenges. The mission will include “organ-on-a-chip” devices to study cellular responses during the journey.
22. Completing the Cycle with Special Soil
Artemis II will transport soil from ten trees that grew from seeds flown on Artemis 1, finalizing the cycle of lunar exploration and growth.
