Artemis II Basics
The Artemis II crew will be the first astronauts from this country to orbit the Moon since 1972.
United States
What is the Artemis program?
NASA’s modern program to return humans to the Moon and prepare for future deep-space missions.
What constellation is the spacecraft that carried the astronauts named after?
Orion
What is the mission path called that loops around the Moon and returns to Earth?
A free-return trajectory.
Why are crewed missions more complicated than robotic missions?
Because humans need air, water, safety, rest, and protection.
The primary mission goal of Artemis II is to orbit this celestial body and return safely to Earth.
The Moon
What is Artemis 2?
The first crewed Artemis mission that will travel around the Moon and return to Earth.
Why did they name the mission and program, Artemis?
Greek mythology - the first missions were named Apollo. Artemis is apollo's twin sister.
Star wars note(because you are taking astronomy) - Luke and Leia were twins as well :)
Why is a free-return trajectory helpful?
It adds safety by helping the spacecraft return toward Earth naturally.
What is a communication delay?
The time it takes for messages to travel between Earth and the spacecraft.
This Artemis II spacecraft will carry astronauts around the Moon for the first time in over 50 years.
Orion
Why is Artemis II important even though it does not land on the Moon?
It tests the spacecraft, systems, and crew operations in deep space.
What does life support do on a space mission?
It provides what astronauts need to survive, like air, water, and temperature control.
Why is traveling to the Moon not a straight-line trip?
Because gravity, motion, timing, and orbital paths shape the spacecraft’s route.
Why is there less room for mistakes in deep space?
Because help is far away, resources are limited, and small problems can become serious.
The Artemis II crew completed the mission in only____ days.

What earlier moon program is Artemis often compared to?
Apollo
Why is power management important on a mission like Artemis II?
Because power is limited and must be used carefully for critical systems.
What force helps shape Orion’s path around the Moon?
Gravity.
In the simulation, what was usually more important than convenience or comfort?
Crew safety and mission success.
Artemis II will be launched by this powerful NASA rocket, known by its initials SLS.
Space Launch System
What is one long-term goal of Artemis beyond visiting the Moon?
Preparing for future missions to Mars.
Name two systems that must work well for the crew to return safely.
Possible answers include communication, navigation, life support, power, or guidance systems.
Why might small navigation corrections matter on a deep-space mission?
Because even small errors can grow over long distances and affect the mission outcome.
What does mission success mean for Artemis II?
A safe crewed mission around the Moon that tests systems and returns the astronauts safely to
