A pioneer of the first successful Mars landings will have his legacy carried toward the Red Planet.

Houston, Texas Celestis, the pioneer of memorial spaceflight services, announced that Andrew “Andy” John Stofan, a NASA leader whose career helped guide the launch of the historic Viking Mars missions, will embark on a future Mars memorial spaceflight.

A symbolic portion of Stofan’s remains will travel toward Mars aboard a planned Celestis mission, creating a powerful connection between one of the architects of humanity’s first Mars landings and the next chapter of interplanetary exploration.

From 1974 to 1978, Stofan directed the Titan-Centaur and Atlas-Centaur launch vehicle offices at NASA. In this role he oversaw sixteen launches supporting major planetary missions, including Pioneer 10 and 11, the Voyager probes, and the Viking spacecraft, the first missions to successfully land on Mars.

The Viking program marked a defining milestone in space exploration. Viking 1 and Viking 2 landed on the Martian surface in 1976, returning the first images and scientific data ever obtained directly from another planet.

Stofan later served in senior leadership roles across NASA, including Acting Associate Administrator for Space Science and Director of NASA’s Lewis Research Center. In 1986 he was appointed Associate Administrator for the Space Station Office, where he reorganized and guided the early development of what would ultimately become the International Space Station.

After a lifetime devoted to advancing humanity’s exploration of space, Stofan’s memorial flight reflects a remarkable symmetry: a career that helped launch spacecraft to Mars will now symbolically continue toward the same frontier.

The mission is part of Celestis’ planned Mars memorial program, which will carry symbolic portions of cremated remains or human DNA toward the Red Planet as part of humanity’s expanding presence in space.

Andrew “Andy” Stofan died on October 26 at the age of 90. He is survived by Barbara, his wife of 70 years, daughters Lynn Kaplan and Ellen Stofan, five grandchildren, and two great-grandchildren.

For nearly a century, audiences around the world have been inspired by the idea that humanity could one day break the bonds of Earth and explore the cosmos. Few people shaped that collective dream more than Willy Ley, a visionary science writer, rocketry advocate, and one of the earliest public voices to articulate what a true Space Age might look like.

In 2026, his story will take an extraordinary new step.

Celestis is honored to announce that a symbolic portion of Willy Ley’s cremated remains will fly aboard Serenity Flight, our next Earth-orbit memorial mission launching from Cape Canaveral. It is a tribute that beautifully aligns with his life’s work: transforming spaceflight from speculation into expectation.

A Legacy Built on Imagination, Science, and Courage

Born in Berlin in 1906, Ley was among the founding members of the Verein für Raumschiffahrt (VfR), the early amateur rocketry society whose ideas shaped the foundations of modern aerospace engineering. After fleeing Nazi Germany in 1935, he became a U.S. citizen and one of America’s most influential science communicators.

His 1949 book The Conquest of Space, illustrated with striking, futuristic imagery, became a touchstone for a generation that would go on to build NASA, design spacecraft, and ultimately walk on the Moon. His work appeared in Life, Time, and Galaxy, bringing the dream of spaceflight into living rooms decades before the first launch pads rose from the Florida coast.

A crater on the far side of the Moon bears his name. He died in June 1969, just weeks before Apollo 11 fulfilled the vision he championed.

A Remarkable Rediscovery

In early 2025, Ley’s cremated remains were unexpectedly discovered in the basement of a Manhattan apartment building, a story first reported by the New York Times.

The rediscovery sparked international interest and renewed appreciation for Ley’s role in shaping humanity’s earliest conversations about space. It also opened the door for a meaningful tribute: bringing him into orbit aboard a mission aligned with the legacy he helped create.

Serenity Flight: A Tribute in Orbit

Serenity Flight will place a symbolic portion of Ley’s remains into Earth orbit alongside other participants who share a common passion for exploration, legacy, and meaning. Like all Celestis orbital missions, the spacecraft will circle our planet for months to years before its natural reentry—creating a poetic, celestial farewell.

To accompany the launch, Celestis hosts multi-day memorial activities, mission briefings, and a launch viewing experience for families.

For Ley, the flight is more than symbolic; it is a long-overdue continuation of the story he helped start.

Be Part of This Historic Mission

Serenity Flight is open for reservations. Families and individuals who feel a connection to Ley’s legacy—or who simply share his passion for the cosmos—may secure a place on this historic orbital mission.

Humanity’s story in space has always been written by dreamers. In 2026, one of its earliest storytellers finally joins the journey.
