After more than five decades of silence, the roar of rockets is about to shake the Florida coast again — and this time, we're going back to the Moon to stay. NASA's Artemis program represents the most ambitious crewed lunar endeavor since the Apollo era, and its next milestone is almost here. With four astronauts strapped into the Orion capsule atop the towering Space Launch System (SLS) rocket at Kennedy Space Center's Launch Complex 39B, humanity stands on the cusp of a new chapter in space exploration.
A Brief History: From Apollo to the Long Silence
The Apollo Era (1961–1972)
The story of humans on the Moon begins with a bold challenge. In May 1961, President John F. Kennedy declared that the United States would land a man on the Moon before the end of the decade. It seemed impossible — but eight years later, on July 20, 1969, Apollo 11 astronaut Neil Armstrong stepped onto the lunar surface, uttering words that echoed across the world.
Six Apollo missions successfully landed astronauts on the Moon between 1969 and 1972, each pushing the boundaries of science and human endurance:
Apollo 11 (1969): First crewed lunar landing. Neil Armstrong and Buzz Aldrin walked on the Sea of Tranquility.
Apollo 12 (1969): Precision landing near the Surveyor 3 probe in the Ocean of Storms.
Apollo 13 (1970): A near-disaster. An oxygen tank explosion forced an abort, but the crew survived a harrowing journey home.
Apollo 14 (1971): Commander Alan Shepard famously hit a golf ball on the Moon's surface.
Apollo 15 (1971): First use of the Lunar Roving Vehicle; exploration of Hadley Rille.
Apollo 16 (1972): First landing in the lunar highlands at Descartes.
Apollo 17 (December 1972): The final Apollo lunar mission. Geologist Harrison Schmitt and Commander Gene Cernan spent over three days on the surface — the longest lunar stay of the program.
When Apollo 17 lifted off from the Moon on December 14, 1972, no one imagined it would be more than 50 years before humans returned.
The Long Hiatus (1972–2022)
After Apollo, NASA shifted its focus to the Space Shuttle program and the International Space Station. Dreams of returning to the Moon flickered in various proposals — the Space Exploration Initiative of 1989, the Vision for Space Exploration in 2004, and the Constellation program — but budget cuts, shifting priorities, and political will repeatedly postponed lunar ambitions. For half a century, the Moon remained out of reach.
Enter Artemis: A New Era of Lunar Exploration
Named for the Greek goddess of the Moon and twin sister of Apollo, NASA's Artemis program was formally initiated in 2017 with the explicit goal of returning humans to the Moon — this time to establish a long-term, sustainable presence. Unlike the Apollo program's "flags and footprints" missions, Artemis aims to build the infrastructure for humans to live and work on and around the Moon, and ultimately lay the groundwork for crewed missions to Mars.
The program is built on three core elements:
Space Launch System (SLS): The most powerful rocket ever built, capable of sending Orion and cargo directly to the Moon in a single launch.
Orion Spacecraft: The deep-space crew vehicle designed to carry up to four astronauts beyond low Earth orbit and return them safely to Earth.
Human Landing System (HLS): Commercially developed lunar landers — SpaceX's Starship HLS and Blue Origin's Blue Moon — designed to ferry crews between lunar orbit and the surface.
The Artemis Missions: A Mission-by-Mission Breakdown
Artemis I — November 2022: The Uncrewed Trailblazer
The program kicked off in spectacular fashion on November 16, 2022, when the SLS rocket launched the uncrewed Orion capsule on a 25-day mission around the Moon. Orion traveled into a distant retrograde lunar orbit, farther from Earth than any spacecraft designed for human spaceflight had ever gone — more than 268,000 miles from our planet.
The mission was largely a success, proving out SLS and Orion's core capabilities. However, post-mission inspection revealed that Orion's ablative heat shield had eroded more than expected during reentry — an anomaly that would drive engineering investigations and ultimately reshape future missions.
Artemis II — April 2026: The Crewed Lunar Flyby (LAUNCHING THIS WEEK)
This is the one the world has been waiting for.
Artemis II is NASA's first crewed mission beyond low Earth orbit in over 50 years. Launching no earlier than Wednesday, April 1, 2026 at 6:24 p.m. EDT, the 10-day mission will carry four astronauts on a free-return trajectory around the Moon and back to Earth — a mission profile comparable to the legendary Apollo 8 in 1968.
The Crew
Astronaut | Role | Historic First |
Reid Wiseman (NASA) | Commander | — |
Victor Glover (NASA) | Pilot | First person of color beyond low Earth orbit |
Christina Koch (NASA) | Mission Specialist | First woman to travel beyond low Earth orbit |
Jeremy Hansen (CSA) | Mission Specialist | First non-U.S. citizen beyond low Earth orbit |
The Mission Profile
The crew will launch aboard Orion atop the SLS from Kennedy Space Center's Launch Complex 39B — the same pad from which Apollo 10 and Apollo 11 departed. After an extensive series of systems checks and maneuvers in Earth orbit, the Interim Cryogenic Propulsion Stage (ICPS) will fire to send Orion on a translunar trajectory.
Rather than entering lunar orbit, Artemis II will execute a free-return flyby — swinging around the far side of the Moon at a distance of roughly 4,700 miles beyond the lunar surface, before the Moon's gravity slingshots the spacecraft back toward Earth. The entire journey to the lunar vicinity takes about three days.
At its farthest point, Artemis II will be farther from Earth than any crewed spacecraft in history. Upon return, Orion will reenter the atmosphere at approximately 25,000 miles per hour, splashing down in the Pacific Ocean off San Diego, where the U.S. Navy will recover the crew.
Road to Launch: A Rocky Path
The path to April 1 has been anything but smooth. Originally targeted for 2024, then 2025, Artemis II encountered a series of setbacks: hydrogen leaks during wet dress rehearsals, an unexpected helium flow issue that triggered a full rollback to the Vehicle Assembly Building in February 2026, and engineering challenges related to Orion's life support system and heat shield.
As recently as March 20, the SLS rolled back out to the launch pad for its final preparations. On March 27, the four-person crew arrived at Kennedy Space Center. As of today, weather is 80% favorable for Wednesday's launch attempt, with primary concerns being cloud coverage and potential high winds.
Commander Reid Wiseman also announced the mission's "zero gravity indicator" — a small plush toy named Rise, inspired by the iconic Earthrise photograph taken by Apollo 8, designed by a student from Mountain View, California, selected from over 2,600 entries worldwide.
Artemis III — Mid-2027: Lander Testing in Earth Orbit
Originally planned as the triumphant return of boots to the lunar surface, Artemis III was significantly redesigned in a February 2026 NASA announcement. Due to ongoing development challenges with the commercial lunar landers and concerns about mission safety, NASA restructured Artemis III into a demonstration mission in low Earth orbit.
The mission will launch the Orion spacecraft and crew to test rendezvous and docking procedures with one or both commercial landers — SpaceX's Starship HLS and Blue Origin's Blue Moon Mark 2. Astronauts will also test the new Axiom Extravehicular Mobility Unit (AxEMU) spacesuits designed for eventual use on the lunar surface. In this respect, the mission is analogous to Apollo 9, which tested the Lunar Module in Earth orbit before Apollo 10 brought it to the Moon.
Artemis IV — Early 2028: The Moon Landing
This is the mission that will make history all over again. Artemis IV is now NASA's first planned crewed lunar landing since Apollo 17 in 1972. Two astronauts will descend to the lunar south polar region — a scientifically rich area that may harbor water ice in permanently shadowed craters — aboard a commercially developed lander, while the other crew members remain in Orion.
The south polar region represents a major departure from the Apollo missions, which all targeted the equatorial zone. Water ice discovered there could be a game-changer, providing resources for drinking, oxygen production, and rocket fuel, making a long-term human presence on the Moon more sustainable.
Total mission duration is expected to be approximately 30 days, with the landed crew spending roughly one week on the surface conducting up to four spacewalks.
Artemis V — Late 2028 and Beyond: Building a Presence
Artemis V is expected to include another crewed lunar landing, with two astronauts continuing scientific surface operations and sample collection. Critically, NASA plans to begin construction of the Artemis Base Camp during this mission — the foundation for a permanent outpost on the Moon.
After Artemis V, NASA has stated its ambition to conduct approximately one lunar mission per year, with each successive mission expanding humanity's foothold on the Moon. Future missions will dock at the Lunar Gateway — an international space station planned for lunar orbit — from which crews will descend to the surface.
Why It Matters
The Artemis program is not merely a nostalgic re-run of Apollo. It is designed from the ground up to be different — broader, more inclusive, and more enduring.
Science: The lunar south pole holds secrets about the early solar system locked in ancient ice and rock. Understanding it could transform our knowledge of planetary formation and the origin of water on Earth.
Sustainability: Unlike Apollo, Artemis is not a sprint — it is designed to build lasting infrastructure. Base camps, lunar resource utilization, and the Gateway station are all stepping stones toward a human presence that could last decades.
Inclusion: The missions have been specifically designed to ensure that the first woman and first person of color to reach the Moon do so under the Artemis banner — a historic expansion of who gets to explore the cosmos.
The Path to Mars: Every technology tested on and around the Moon — life support, deep-space navigation, in-situ resource utilization, long-duration habitation — brings NASA closer to the ultimate goal: sending humans to Mars.
The Launch Window: Don't Miss It
Mark your calendars. The Artemis II launch window opens Wednesday, April 1, 2026 at 6:24 p.m. EDT, with an 80% favorable weather forecast. If Wednesday's attempt is scrubbed, NASA has additional launch opportunities within the April window.
For the first time since December 1972, four human beings will venture beyond the safety of Earth orbit, swing around the Moon, and return home. Artemis II won't land — but it will prove that we can go back. And soon, we will.
The Moon is no longer just a destination from the past. It is the gateway to our future.
