Returning to the Moon: Artemis 2 Quiz

The Artemis II crew is historic because it includes Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen. This crew represents a more diverse group of explorers, including the first woman and person of color to fly a lunar mission, as well as the first international (Canadian) partner.

Artemis II will use a "free-return trajectory." This means that after the initial engine burn, Earth's and the Moon's gravity will naturally pull the spacecraft around the Moon and back toward Earth. This path is a safety feature; if the engines fail near the Moon, the crew will still return home.

True. The mission is designed to last about 10 days from launch to splashdown. During this time, the crew will test communication, navigation, and life-support systems to ensure they can handle the environment of deep space for longer future stays on the Moon.

The Moon is about 238,000 miles away from Earth. Artemis II will travel slightly beyond the Moon before heading back. This scale highlights the vast distance of the Earth-Moon system compared to the International Space Station, which orbits only about 250 miles above Earth.

Artemis II is a "test flight." Engineers need to ensure that the air stays breathable, the crew is protected from solar radiation, and the heat shield can withstand temperatures of 5,000°F when returning to Earth. Since there are no trees on the Moon, that is not a mission concern.

Similar to the Apollo missions, the Orion capsule will use parachutes to slow down and land in the ocean. This "splashdown" method allows for a safe landing after entering the atmosphere at 25,000 miles per hour. Recovery teams from the U.S. Navy will be waiting to pick up the crew.

True. The mission's path is designed to take the crew thousands of miles beyond the far side of the Moon. This will set a new record for the furthest distance from Earth that a human-crewed spacecraft has ever reached, surpassing the record set by Apollo 13.

NASA will test laser (optical) communication to send high-definition video and data to Earth. Lasers can carry much more information than traditional radio waves, which will be essential for future missions when astronauts need to send large amounts of scientific data back from the lunar surface.

The Gateway is a planned small space station that will orbit the Moon. It will serve as a communication hub, a science lab, and a short-term habitation module for astronauts. Artemis II tests the spacecraft that will eventually transport crews to and from this station.

While both programs go to the Moon, Artemis uses 21st-century technology and materials. Unlike Apollo, which was about "getting there first," Artemis is focused on sustainable exploration—learning to live and work on the Moon long-term. Artemis also involves international partners like Canada and Europe.

The International Space Station is protected by Earth’s magnetosphere, which blocks much of the Sun's harmful radiation. Artemis II travels far beyond this protection. Orion must have specialized shielding and "safe havens" inside the cabin to protect the crew from solar flares and cosmic rays.

True. Since the last Apollo mission in 1972, no humans have traveled to the Moon. The Artemis II crew will be the first eyes to witness the rugged, cratered landscape of the lunar far side, which is never visible from Earth.

NASA chose the name Artemis because she is the twin sister of Apollo. Since the first missions were named Apollo, the new program is named Artemis to signify a return to the Moon with a new generation of explorers, including the first women.

Artemis III is the mission currently planned to perform the actual lunar landing. Artemis II provides the essential data on how the spacecraft handles a human crew in deep space before the more dangerous landing phase is attempted.

The Moon is an ideal testing ground. It is close enough to Earth (3 days) for a rescue if needed, but harsh enough to test life-support and habitats. We can also learn to harvest lunar water ice for fuel, which is a skill we will need to survive a multi-year trip to Mars.

Reentering from the Moon is much faster than reentering from low-Earth orbit. Orion will hit the atmosphere at 25,000 mph. The friction with the air will create a glowing plasma shield around the capsule, testing the heat shield's ability to protect the astronauts from extreme heat.

Artemis II is the first crewed flight of NASA's Artemis program. Its goal is to test the Orion spacecraft’s life-support systems with humans on board as they fly around the Moon. This mission paves the way for the Artemis III mission, which intends to land humans on the lunar surface.

False. Artemis II is a "flyby" mission. The crew will travel around the Moon and return to Earth without landing. This allows NASA to verify that all spacecraft systems operate safely with a crew before attempting a complex lunar landing on the next mission.

The Space Launch System (SLS) is NASA's most powerful rocket to date. It is designed to send the Orion spacecraft, its crew, and supplies to the Moon. While the Saturn V was used for Apollo, the SLS is the modern heavy-lift rocket built for 21st-century deep space exploration.

Orion is the command module designed specifically for deep space missions. It features advanced radiation shielding and life-support systems to keep the four-person crew safe during their journey to the Moon and their high-speed reentry into Earth's atmosphere.
