Hi Reddit!

I am Steven Hauck, a planetary scientist, professor of Earth, Environmental, and Planetary Science at Case Western Reserve University, and the Editor-in-Chief of the American Geophysical Union journal JGR-Planets, which is celebrating its 25th anniversary this year. I have been a member of the Science Team on NASA’s MESSENGER mission to Mercury and I research (primarily solid) planetary bodies from their make-up and processes in their deepest interiors to the geology (e.g., faults and impact craters) on their surfaces.

Exploration of the solar system starting in the 1960s gave rise to a new field of science: planetary science. Robotic and human exploration of moons, planets, asteroids, comets, and other objects in our solar system has provided a whole new family of worlds to discover. Over the past 25 years, multiple nations have sent a multitude of spacecraft throughout the solar system, from the MESSENGER mission to the innermost planet to the New Horizons mission to Pluto and the Kuiper Belt, and missions to the Moon, Mars, Jupiter and Saturn, comets, asteroids and many more places. And there are still so many places in our solar system that we haven't seen enough of yet. My journal, JGR-Planets, publishes new scientific articles seeking to understand the origin, interactions and history of all the objects in our solar system other than the Sun. Check out the JGR-Planets webpage.

I am looking forward to answering many questions about exploring the solar system, what we are learning about the planets, what the planets are made of and how they operate, and more.

I’ll be back at noon EST (9 am PST, 5 pm UTC) to answer your questions, ask me anything!
