Welcome from the Department Head, Tim Swindle
Welcome to the University of Arizona’s Department of Planetary Sciences (PtyS) and Lunar and Planetary Laboratory (LPL). Let me tell you a little about this institution.
LPL was founded in 1960 by planetary astronomer Gerard P. Kuiper, after whom the Kuiper Belt of icy objects in the outer Solar System and the Kuiper Prize (the top honor of the world’s largest organization of planetary scientists) are named. Most of the original work was based on observations using telescopes, but as the exploration of the planets expanded in scope, so did LPL. In 1973, PtyS was formed, to educate succeeding generations of planetary scientists.
Our dedicated faculty, research staff, and students come from a variety of backgrounds, including physics, astronomy, geosciences, chemistry, and engineering, but have a common interest in planets. In fact, the interdisciplinary nature of planetary science is one of its appeals for many of us, as we have to learn something of many of those other disciplines just to communicate, not to mention to succeed in understanding what is happening on the planets.
LPL’s expertise has also broadened as the field has expanded: some of us still use telescopes, others work with spacecraft, others work in laboratories analyzing extraterrestrial materials like meteorites or simulating the conditions on the planets, and still others primarily work on the theoretical work required to explain all the observations. The list of objects we study has broadened, too. When LPL was founded, Kuiper had proposed a belt of objects orbiting beyond Neptune, but none (except Pluto) had been found -- now we study the Kuiper Belt and Kuiper Belt Objects. Only a few asteroids were known at the time -- our asteroid survey programs have discovered hundreds of thousands, and we are leading OSIRIS-REx, a spacecraft mission to an asteroid. No planets orbiting stars other than the Sun were known until the 1990s -- now research on exoplanets is a large part of what we do.
The University of Arizona is one of the nation’s best research universities, annually ranking among the top in the nation in external financial support for research in the physical sciences. LPL is comparably highly ranked. A 2011 survey showed that planetary scientists at the University of Arizona (the vast majority of them in LPL) published more research papers in the previous 10 years than those at any other university in the world.
We also have a commitment to education. Through the PtyS department, we teach courses ranging from General Education courses on basic science for incoming university freshmen to research seminars for advanced graduate students. The vast majority of our Ph.D. graduates have remained in the field of planetary sciences, with faculty positions or research jobs at NASA and various private institutes, and many of them are among the international leaders in the field. In addition to formal classes, we host the campus-wide Teaching Teams Program and the state-wide Arizona Space Grant Consortium.
