How to use the Stayputnik?

So, I've been trying to do the career and am at a stage where I think I ran out of science on Kerbin to do, and so I was trying to get started on the contract to get to the Mun, the only problem is, I didn't want to risk Kerbals on the first mission to the Mun, so I wanted to send a probe, and the only probe I have access to is the Stayputnik, and whatever I do, I can't get it to stay straight on during launch, much less get to space.
