Adam Diedrich Steltzner (born 1963) is an American NASA engineer who works for the Jet Propulsion Laboratory (JPL). He worked on several flight projects including Galileo, Cassini, Mars Pathfinder, Mars Exploration Rovers (MER). He was the lead engineer of the Mars Science Laboratory, Curiosity rover EDL phase (Entry, Descent and Landing), and helped design, build and test the sky crane landing system.
The media has portrayed Steltzner as a "rock and roll" engineer. NPR's Morning Edition said "he has pierced ears, wears snakeskin boots and sports an Elvis haircut," while the EE Times called him "a bit of a hipster" and a "new breed of engineer" who is media savvy.
Steltzner, born 1963, is a native of the San Francisco Bay Area and came from a family that was financially well off, his father being the heir to the Schilling spice fortune. He struggled in classes in high school, earned a failing grade in geometry, and was told by his father he would never amount to anything but a ditch digger. "I was sort of studying sex, drugs and rock and roll in high school," says Steltzner. After high school he played bass and drums in new wave bands. He studied jazz at Berklee College of Music in Boston, for less than a year. As The New Yorker put it, "He was a college dropout and small-town playboy (he briefly dated the model Carré Otis), an assistant manager at an organic market and an occasional grower of weed. He had few skills and fewer prospects." Around 1984, while driving home from music gigs at night, he noticed how the position of the constellation Orion was in a different place than before. This fascinated him, so he decided to take an astronomy class at College of Marin, but he was required to complete a class in physics first, and it was there he had a revelation: nature could be understood and predicted. As Steltzner put it, "I had found religion." By 1985 he quit music and devoted himself full time to the challenge of school. His education included Tamalpais High School (1981) and College of Marin ; a Bachelor of Science degree in mechanical engineering at University of California, Davis (1990); a Master of Science degree in applied mechanics at California Institute of Technology (1991); and a PhD in engineering mechanics at University of Wisconsin–Madison (1999).
Steltzner is married to wife Trisha, who also works at JPL, and has two daughters, Caledonia and Olive. His second daughter was born three weeks after the Mars landing in 2012.
Steltzner is employed at NASA's Jet Propulsion Laboratory where he has worked for about ten years designing, testing and building the sky crane landing system for the Curiosity rover. Steltzner was phase lead and development manager for EDL (Entry, Descent and Landing) of the lander, which successfully landed on Mars on August 5, 2012. The sky crane is an entirely new technology system, Steltzner said of it "When people look at it...it looks crazy. That's a very natural thing. Sometimes when we look at it, it looks crazy. It is the result of reasoned, engineering thought. But it still looks crazy." The sky crane allows for a precise landing ellipse opening up many areas of Mars for exploration that were previously inaccessible due to uneven terrain.
Steltzner joined JPL in 1991, in the Spacecraft Structures and Dynamics group. He worked on several flight projects including the Shuttle–Mir Program, Galileo, Cassini, Mars Pathfinder, Mars Exploration Rovers (MER) and Mars Science Laboratory as well as several mission proposals, pre-Phase A projects and technology development efforts. Initially employed as a structures and mechanics personnel, he gravitated towards landing events and Mars Entry, Descent and Landing (EDL) systems. He was the landing systems engineer on the cancelled comet mission Champollion and the mechanical systems lead for EDL on MER. When asked what he would like to do next, Steltzner says, "I'd like to see a Mars sample return. I'd like to land on the surface of Europa – the most likely place in the solar system for life. And third, I'd like to float a boat on the methane lakes of Titan."
Steltzner is often profiled by the press in human interest stories with a focus on a "rock and roll" engineer image; for example he was called "the face of the 2012 Mars Science Laboratory mission" by the EE Times, who also called him "a bit of a hipster"; he was interviewed on National Public Radio which noted his "Elvis haircut", and profiled again on NPR in a piece called "Red Planet, Green Thumb: How A NASA Scientist Engineers His Garden". Steltzner also participated on the NPR radio quiz program Wait Wait... Don't Tell Me! in 2012. He has been profiled similarly in other sources. A chapter-length biography of Steltzner in the book Going to Mars (2004) is titled "Elvis Lives" after the rock and roll star who Steltzner supposedly resembles, which Esquire said "calls back to NASA's halcyon days in the late 50's and early 60's".
In 2004, he was among the scientists and engineers featured on the NOVA episode "MARS Dead or Alive" (aired January 4, 2004), which chronicled the process that ultimately delivered the rovers Spirit and Opportunity to Mars. The episode was nominated for an Emmy in 2004. He also appeared in the NOVA episode "Welcome to Mars" (2005), and other TV documentaries including Countdown to Mars (2003), Bouncing to Mars (2003), Spirit of Exploration (2005), What Went Right (2006), Mars Rising (2007) episodes "Journey to the Red Planet" and "Seven Minutes of Terror", Horizon (2012) episode "Mission to Mars: A Horizon Special" and a Studio B with Shepard Smith episode dated August 6, 2012.
