A determination of Newton´s gravitational constant using the MSL torsion balance

Summary form only given, as follows. We will describe the results of a new determination of the Newtonian gravitational constant (G) made since our last value reported at the 1994 CPEM. At the 1996 CEPM we reported a number of difficulties in completing the measurement in progress at that time. We have now solved all of these problems and at the time of writing believe that we will be in a position to report an improved value of G. The paper will briefly report the differences in the measurement since the last CPEM and present our latest result and its uncertainty.
