The OSIRIS-REx Laser Altimeter (OLA) will provide a three-dimensional map of asteroid Bennu’s shape, which will allow scientists to understand the context of the asteroid’s geography and the sample location. OLA is provided by the Canadian Space Agency in exchange for Canadian ownership of a portion of the returned asteroid sample. Credit: NASA’s Goddard Space flight Center/Katrina Jackson

Hurricane Forecasts Rely on Modeling the Past

Improving hurricane forecasts means testing historical storms with today's sophisticated models and supercomputers. NASA and NOAA work together in gathering ground and satellite observations, as well as experimenting with research forecast models. As a result of this collaboration, model resolution has increased, and scientists are discovering more about the processes that occur within these powerful storms. The Global Precipitation Measurement (GPM) Mission is a joint NASA and Japan Aerospace Exploration Agency (JAXA) mission that measures all forms of precipitation around the globe. GPMs Microwave Imager, or GMI, has proven useful in seeing beneath the swirling clouds and into the structure of tropical cyclones. The information gathered by GPM and other missions will be used to improve forecast models.
Barton Corner Bridge Project

In August 2014 we completed replacement of the Barton Corner Bridge, which carries four lanes of I-95 plus two auxiliary lanes at a busy interchange with Route 2 on the Warwick/West Warwick line. Using accelerated bridge construction, we built two halves of the bridge on land adjacent to the overpass, and then moved them into place. This enabled us to build the bridge much faster compared with conventional construction methods, which would have taken twice the time. This approach also allowed us to do the work with no impact to Interstate traffic prior to installation.
