What are the important attributes in 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!

One place that you might want to start your research is the NASA site for "The Space Shuttle Launch Team" here:
http://science.ksc.nasa.gov/shuttle/countdown/launch-team.html
This site has a lot of links contained within it that may lead you to the type of information you're seeking.

Another possible source you may want to investigate is the Wikipedia article on "Space Shuttle Launch Commit Criteria" here:
http://en.wikipedia.org/wiki/Launch_commit_criteria.

A third site (one that, perhaps, most closely addresses your question) is here: http://www.aero.org/publications/crosslink/winter2001/03.html

Welcome to SDC forums!

Well, if you're looking at a satellite, the space shuttle information may be a bit overwhelming. The Space Shuttle has a set of launch commit criteria that dwarfs that of any other vehicle. One of the biggest factors is the need to support the various abort modes that involve landing right away -- Return To Launch Site (RTLS), Trans-Atlantic Landing (TAL), and Abort Once Around (AOA). So they need not just suitable launch weather but suitable landing weather at the same time. They also have a lot more restrictions based on the fact that there are people on board, and losing crew is far worse than losing a mere hundred-million-dollar spacecraft.

I bet you can find launch commit criteria for other vehicles out there on the Web. They will vary based on the rocket's performance, the launch site, what's downrange, and mission-specific details like the duration of a launch window. With a three-hour launch window, you have better odds of launching than you do with a five-minute window, since there are better odds of weather clearing up in that timeframe. On the flip side, shorter windows will probably drive at least a little bit of "go fever", and there is probably some risk associated with repeated tanking -- if you have to scrub three times after tanking, you will have subjected the tanks to a lot more stress than if you had been able to launch on the first try.

That third article of csymth3025's is excellent reading on the subject.

To put it simply you need a robust and reliable booster, and secondly bullet proof avionics strong enough to handle the vibrations and G loads of the launch without a failure,
