April 1: This Full Moon Is No Joke

Here is a sentence that sounds like a prank but is entirely, wonderfully true: tonight, on April Fools' Day, a Full Pink Moon will rise over Kennedy Space Center just hours after NASA attempts to launch four astronauts toward the Moon for the first time since 1972. The Full Pink Moon reaches peak fullness at 10:12 p.m. ET — while the Artemis II crew, if all goes to plan, will already be arcing through the darkness of high Earth orbit, 244,036 miles from the same lunar surface that tonight's Moon will illuminate in silver light. The calendar today is doing something it has never done before: staging a crewed Moon launch beneath a full Moon named for the flowers of spring, on the most mischievous day of the year. History has a sense of humor.

The Moon That Named Easter — and Spring Itself

Despite its name, the Pink Moon will not appear pink. It takes its name — recorded for centuries in the Old Farmer's Almanac and rooted in Indigenous North American tradition — from the moss pink, or wild ground phlox, one of the earliest widespread wildflowers of spring across the eastern half of North America. When this Moon rose, the phlox bloomed. Other traditional names carry the same seasonal weight: the Egg Moon, the Sprouting Grass Moon, the Moon When the Geese Lay Eggs. All of them speak to the same ancient observation: the full moon of April announces that winter is over and the earth is returning to life. It will rise golden above the horizon at moonrise, appearing larger than usual thanks to the Moon illusion — a beautiful trick of perspective that has mystified observers for as long as there have been eyes to notice it — before climbing to its full cold brightness by 10:12 tonight.

This particular Pink Moon carries additional weight in the Christian calendar: it is the Paschal Moon — the first full moon of spring following the ecclesiastical equinox — and it is the moon that sets the date of Easter. The calculation, established by the Council of Nicaea in 325 CE and refined over subsequent centuries, defines Easter as the first Sunday after the Paschal Moon. This year's Paschal Moon falls today, April 1. Easter follows on April 5. The same moon that has governed the timing of one of the world's great religious celebrations for seventeen centuries is tonight also the backdrop for humanity's return to deep space. The universe, apparently, does not miss its cues.

Step outside tonight, away from city lights if you can, and watch it rise. It will come up golden and enormous above the horizon — that familiar Moon illusion making it look almost close enough to touch — and it will climb the sky as the night deepens, pulling toward its peak brightness just after 10 p.m. Somewhere above you, if today's launch succeeds, four human beings will be watching the same Moon from a perspective no one alive has ever had: from space, heading toward it. In ancient Egypt, the palm was carried at funerals because it symbolized eternal life — and tonight humanity carries its own kind of palm branch, a 322-foot rocket pointed at the same pale light that has watched over every human life ever lived. Go outside tonight. Look up. It is no joke: the Moon is full, it is spring, and we are going back.
