Planetary Science & Engineering: Exploring the Solar System
Michael Amato from NASA’s Goddard Space Flight Center discusses the specialized engineering and scientific collaboration required to build missions for the Moon, Mars, and beyond. He highlights how Goddard contributes to major missions, including the search for life on Mars and the study of the extreme environments of Venus.
[00:00:13] Michael Amato leads the Planetary Line of Business at NASA Goddard. His role involves bringing together scientists and engineers to propose and build new missions. Goddard is unique because it houses everything from the initial scientific idea to the actual construction and testing of the spacecraft in one location.
The Architecture of a Mission
[00:01:21] A successful planetary mission requires a “system of systems.” Engineers must design spacecraft that can survive the vacuum of space, extreme radiation, and massive temperature swings. At Goddard, this work is supported by massive test facilities, including thermal vacuum chambers and “shake tables” that simulate the violent vibrations of a rocket launch.
[00:02:45] One of the key areas Michael discusses is the search for life. This requires highly specialized instruments, such as mass spectrometers, which can “smell” or “taste” the atmosphere or soil of another planet to look for organic molecules. These instruments are developed at Goddard and have been used on missions like Curiosity and Perseverance on Mars.
Destination: Venus
[00:03:55] Exploring Venus presents some of the toughest engineering challenges in the solar system. The surface of Venus is hot enough to melt lead, and the atmospheric pressure is equivalent to being 900 meters underwater on Earth. Michael explains that NASA is returning to Venus with missions like DAVINCI to study its atmosphere and determine if the planet was once habitable.
[00:05:15] To survive these conditions, engineers must build “pressure vessels”—thick-walled titanium spheres that protect the delicate electronics inside from being crushed or roasted during the descent to the surface.
Building Your Own Future in Space
[00:06:30] Michael emphasizes that there is no single “right” way to get to NASA. The agency needs a diverse workforce, including mechanical engineers, software developers, project managers, and even artists to visualize these distant worlds. For students interested in this field, the best approach is to stay curious and participate in hands-on projects, like the AVA Challenge.
[00:08:10] “We are entering a new golden age of planetary exploration,” Michael says. With more missions planned for the Moon and the icy moons of Jupiter and Saturn, the next generation of explorers will be the ones to finally answer the question: Are we alone in the universe?
