An estimated 400,000 spectators are anticipated to converge upon Florida's Space Coast for the launch of Artemis II, eager to witness the historic ascent of a rocket destined for lunar orbit.
Among them is eight-year-old Isiah, who expresses his excitement by stating, "People going up to the Moon is kind of cool." This evening, a crew of four astronauts will embark on a journey intended to fly around the Moon, potentially venturing farther from Earth than anyone has traveled before.
While NASA's 10-day test flight does not include a landing on the Moon, the astronauts may be privy to views of the lunar surface that have not been seen by human eyes before.
Amanda Garcia, who has journeyed over 1,000 miles from New Mexico for the launch, shares her enthusiasm: "I'm pretty excited about it. I came out here to see it, and I heard it's gonna be a great show. A lot of people are going to be here."
Throughout the areas surrounding the Kennedy Space Center, including the lagoons and beaches of Titusville and Cocoa Beach, local bars are promoting "moonshots," and hotels are advising guests to expect delays as traffic swells with the influx of visitors.
Local officials are anticipating a "historic influx" of tourists, predicting an economic impact of approximately $160 million (£121 million). They have established traffic plans for an evening where highway lights will compete with the illuminated launch towers and the glow of camper van barbecues.
Just a mile from the launch pads, Brenda Mulberry, the owner of Space Shirts, is preparing for an exceptionally busy day. With 40 years of experience selling NASA merchandise, her shop on Merritt Island features an array of T-shirts adorned with hand-drawn rockets, mission patches, and moonscapes, all set to cater to the wave of visitors typically attracted on launch days. However, Mulberry notes that this launch holds a special significance. "We've wanted to go back to the Moon since the '70s. People are excited. People are beyond excited," she remarks.
In anticipation of the largest customer surge in her history, Brenda has increased her stock. "I want to have the first T-shirt shop on the Moon," she jokes. "Because if you've been there, you get the T-shirt, right?"
Future Artemis missions aim to land humans on the Moon for the first time since 1972, with the added goal of establishing a permanent base to leverage the Moon's natural resources as a launching pad for missions to Mars.
Reid Wiseman, the mission commander for Artemis II, expressed hope that the return to lunar exploration would serve as inspiration for the next generation. "In our lifetime, we've looked at the Moon knowing that people had been there. And now in the Artemis generation, kids will walk out and look at the Moon going, we are there. We are there now, and we are going further into our solar system."
As the evening approaches, all eyes will be set on Launch Pad 39B, the historic site from which the United States' Apollo program first landed humans on the Moon in 1969. Positioned on this pad is NASA's Space Launch System (SLS) rocket, towering at 98 meters (321 feet)—the heaviest rocket ever launched by the agency. Atop the rocket is the Orion capsule, roughly the size of a small van, where the four astronauts will reside for the next ten days in close quarters. This mission marks the inaugural flight for the capsule with a human crew onboard.
Scheduled for launch between 18:24-20:24 local time (23:24-01:24 BST) on Wednesday, the astronauts will enter the Orion capsule approximately four hours prior to liftoff, having undergone years of training together.
The crew consists of Commander Wiseman, Pilot Victor Glover, and astronauts Christina Koch and Jeremy Hansen, a Canadian fighter pilot making his first journey into space.
Once in orbit, Orion will spend its initial day in high Earth orbit conducting manual flying exercises and testing life support systems before setting its course toward the Moon.
On Day 2, a critical trans-lunar injection burn will position the spacecraft on a trajectory that naturally loops it around the Moon and eventually back to Earth, with minor correction burns to refine the course.
Each day of the mission presents unique tests and challenges for the crew, with Day 6 being particularly notable as Orion is set to travel around the far side of the moon, temporarily losing all radio contact for about 40 minutes—an interval during which flight controllers will be unaware of the capsule's status.
At an altitude of approximately 4,000–6,000 miles above the Moon's surface, Orion is expected to exceed Apollo 13's record distance of around 250,000 miles (400,000 km) from Earth, depending on its trajectory.
In the subsequent days, Orion will naturally reenter the Earth’s gravitational pull due to the same trajectory that launched it outbound, with course correction maneuvers ensuring that the capsule reenters the atmosphere at the proper angle.
The final day will require the crew to brace for the intense re-entry into Earth's atmosphere at speeds of about 25,000 mph (40,000 km/h), a phase during which Orion's heat shield will need to withstand extreme temperatures.
Following the uncrewed Artemis I test flight, engineers identified that fragments of the heat shield’s coating had deteriorated during the two-stage "skip" re-entry maneuver. For Artemis II, a similar approach will be employed, albeit with adjustments to the angle and timing to minimize exposure during the initial dip. This will mark the first crewed test of the revised descent strategy.
If Artemis II progresses as planned, the next large gathering at the Space Coast will likely be for another test flight, moving ever closer to the reality of humans stepping on the Moon once again, nearly fifty years since the last footprints were left.
Amidst the marsh grasses and launch pads, one can be assured that someone will be proudly wearing one of Brenda Mulberry's shirts, perhaps envisioning the day her logo appears not only on Florida cotton but in historical photographs taken on the Moon.
