On Space Launch Complex 2 at Vandenberg Air Force Base in California, a solid rocket motor, or SRM, is lifted alongside the mobile service tower. The SRM will be moved inside the tower and attached to the Delta II first stage, which is the launch vehicle for the OSTM/Jason-2 spacecraft. The OSTM, or Ocean Topography Mission, on the Jason-2 satellite is a follow-on to Jason-1. It will take oceanographic studies of sea surface height into an operational mode for continued climate forecasting research and science and industrial applications. This satellite altimetry data will help determine ocean circulation, climate change and sea-level rise. OSTM is a joint effort by the National Oceanic and Atmospheric Administration, NASA, France’s Centre National d’Etudes Spatiales and the European Meteorological Satellite Organisation. OSTM/Jason-2 will be launched aboard a United Launch Alliance Delta II 7320 from Vandenberg on June 15. Photo credit: NASA/Dan Liberotti
