what are the important attributes for launching a satellite?

Hello all,we are now doing a data-mining project to predict whether a satellite launching will be successful or not.
We are now using attributes like weather condition and wind speed and mass of the satellite for prediction whether a launching is successful or not.
But, our attributes are far from enough, and we really couldn’t think of more. So I am asking for help here, could you suggest some other attributes that are important in determining the success of launching of a satellite. Also, please only suggest those attributes whose values for most satellites could be easily obtained through the web.
Thanks in advance!
