NASA Leader Behind Viking Mars Missions to Embark on Future Mars Memorial Spaceflight

Wednesday, April 8, 2026

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.
