Cosmic Explorations Speaker Series

The LPI at 50: A Half Century of Solar System Exploration

The Lunar and Planetary Institute (LPI) has been part of NASA’s adventure of exploring the solar system since 1968. Our understanding of the solar system has changed greatly in the past 50 years. What was known about the solar system 50 years ago? How has our knowledge evolved in that time? How are current planetary missions contributing to our evolving view of the solar system? Join the LPI and our guest speakers as we explore these questions with a focus on recent and current missions during the 2018–2019 Cosmic Explorations Speaker Series.


All Cosmic Explorations Speaker Series presentations are streamed live through the USRA Ustream channel.

Recordings of past presentations can be viewed on the LPI YouTube channel and in the Cosmic Exploration Speaker Series archive.

Cosmic Explorations Speaker Series presentations begin at 7:30 p.m. and are free of charge. Presentations are held at the USRA building at 3600 Bay Area Boulevard, Houston. For more information, please call 281-486-2163 or e-mail
