CAPE CANAVERAL, Fla. — NASA’s Apollo missions are legendary, and now, the space agency is ready to embark on another exciting journey with the Artemis program. As four astronauts prepare for a trip to the moon, it’s hard not to compare Artemis to Apollo.
The Apollo missions first brought humans to the moon with Apollo 8, while Artemis II will make a safer pass around the moon. A key difference? The Artemis crew represents a broader spectrum of humanity, including a woman and a person of color, along with a Canadian astronaut. As NASA astronaut Christina Koch pointed out, Artemis is a new chapter, not just a repeat of Apollo.
Building Up to the Moon
NASA achieved the Apollo moon landing in just eight years. In contrast, progress with Artemis has been slower due to shifting goals and numerous delays. The Artemis rocket, the Space Launch System (SLS), hasn’t seen much action yet, flying only once in a test flight three years ago.
In February, NASA’s administrator made changes to keep Artemis on track. They plan to add a mission between Artemis II and the moon landing planned for Artemis IV in 2028. Next year’s Artemis III will keep things close to home to test various systems before heading for the moon.
Facing Competition
During the Apollo era, the Soviet Union was the main competitor in space. Today, the focus has shifted to China, which aims to land astronauts on the moon’s south pole by 2030. This area is believed to contain ice that could one day provide essential resources for lunar missions. NASA is just as determined to reach the moon first.
Rockets Then and Now
The iconic Saturn V rocket that powered Apollo missions stood 363 feet tall, while the Artemis SLS is 322 feet but boasts more thrust. While Saturn V rockets had multiple launches before carrying astronauts, the SLS has flown just once. This slow pace has led to several delays, including fuel leaks. NASA now aims for a launch in April.
Comparing Early Missions
Apollo 8 was a groundbreaking mission. Frank Borman, Jim Lovell, and Bill Anders orbited the moon in 1968, taking calculated risks. For Artemis II, NASA has opted against a lunar orbit, focusing instead on testing the Orion capsule’s life-support systems.
Both missions occur during challenging times. Artemis II pilot Victor Glover expressed hope that their mission might inspire people during difficult moments.
Learning from the Past
Before heading to the moon, the Artemis crew will spend a day in Earth’s orbit to ensure everything functions smoothly. The mission will use a similar free-return trajectory as Apollo 13, which safely brought its astronauts home despite a near-disaster.
Suiting Up for Space
Apollo astronauts wore heavy, limited suits for both launch and lunar walks. Artemis astronauts, however, will have new suits designed for different phases. The crew will sport orange suits for launch and re-entry but will switch to specialized suits for moonwalking.
NASA has teamed up with private companies to design these suits, one created by Axiom Space for lunar activities.
Long-term Aspirations
Unlike Apollo, which focused on beating the Soviets, Artemis aims for a sustainable lunar presence and eventually a Mars mission. The first Artemis landing could enable astronauts to stay for nearly a week—far longer than the Apollo surface missions.
NASA is investing $20 billion over the next seven years to establish a base on the moon. This ambitious plan includes habitats, rovers, and more, pushing for innovative solutions for living on another celestial body.
Understanding the journey from Apollo to Artemis not only highlights the scientific advances of the last few decades but also reflects a more inclusive view of who gets to explore space. NASA’s vision for the future is ambitious and hopeful, aiming to inspire a new generation of explorers.
