19th International Workshop on Laser Ranging - Celebrating 50 years of SLR09/24/2014
The National Aeronautics and Space Administration (NASA), along with the Smithsonian Astrophysical Observatory, and the International Laser Ranging Service (ILRS), are pleased to announce that the 19th International Workshop on Laser Ranging will be held in Annapolis Maryland during the week of October 27-31, 2014 at the Historic Inns of Annapolis.
October 31, 2014 will mark the 50th anniversary of the first successful SLR measurement, conducted at what is now the Goddard Geophysical and Astronomical Observatory (GGAO). The theme for this workshop, "Celebrating 50 Years of SLR: Remembering the Past and Planning for the Future" will allow us to look back on our many accomplishments and present plans for future advances in SLR technology and science.
