I took the Yellow/Green line to L'enfant Plaza, and since I had the stroller, I took the elevator up- it's at the very end of the platform. Once outside, I walked (it was left for me) about a block or two toward C Street (it turns into Maryland Ave to the right), then once I crossed C Street/Maryland Ave in front of me I saw the sign with the Smithsonian Map. The Air and Space Museum and the stroller/accessible entrance was directly across the street to my right. Click here for a Map, if you need a visual.
You can also take the Orange/Blue line to Smithsonian but I haven't tried that way yet, so you would have to ask the Metro attendant for directions once you get off the train and/or study the map at the link above.
Once inside the Museum, the Einstein Planetarium is upstairs, but go in past security and to the right to get your free tickets into the show from the IMAX ticket booth. On the way to the ticket booth, you will pass the elevator on your right (again, because of the stroller), just go back here to go upstairs and the Planetarium entrance will be to your left.
