The Colloquium Lectures at NASA Langley provide monthly lectures and demonstrations related to science and technology. These lectures are intended to stimulate the creative processes of Langley employees, and enhance the quality of life at Langley by providing more opportunities for learning. These lectures are open to NASA employees, NASA contractors, and other invited guests. The 40th anniversary of the Colloquium Series was celebrated in 2011.

Information is available about additional upcoming Colloquium Lectures, recent past lectures, and all lectures since the series began in October 1971.

The next Colloquium lecture will be held in the Pearl Young Theater of the Integrated Engineering Services Building on February 3, 2015 at 2:00 p.m. Kevin M. Heath, Major USAF, will present F-22 Raptor – Baseline Capabilities and Current Operations.

The Sigma Series Lectures, presented at the Virginia Air and Space Center in downtown Hampton, provide to the general public this same opportunity for exposure to interesting technical topics. These lectures, however, are usually at a somewhat less detailed level, because the audience may consist of people with non-technical backgrounds in addition to local high school and college students.

The next Sigma Series Lecture will be held on March 24, 2015 at 7:30 p.m. Historians Roger Launius, John Anderson, and Tom Crouch will highlight A Celebration of the Centennial of NACA.

Information is available about additional upcoming Sigma Series Lectures and recent past lectures.

The guests and topics for both the Colloquium and Sigma Series Lectures are selected by a committee of NASA Langley employees representing the different technical organizations at the Center. If you have a suggestion for a future lecture topic, please contact the committee.
