The Cloudsat radar was successfully tested. It is working perfectly. You might be interested to know a little about the sequence of events when a spacecraft is launched. It will get to the right speed and altitude, and it needs to separate from the launch vehicle. Then there is a transition from battery power to solar power (this had better be successful within a few hours from launch). After that there are a series of manuevers to get the right orbit. In the case of Cloudsat, this will take some time because it is flying in formation with two other satellites. While these manuevers take place, everything on board the spacecraft is tested, and the science instruments are often calibrated to obtain the best possible accuracy. This whole set of activities is the second part of "launch operations", and will usually take 30 to 60 days.
