We have a very inexpensive telescope (<$35) with very nice optics that we got here: https://www.galileoscope.org/. With a sturdy tripod and some practise you can see 4 moons of jupiter, rings of Saturn, and the moon looks spectacular. Very satisfying and not huge expense. They also have stargazing projects at the site that are designed for the telescopes capabilities.

It's been suggested to me that several wonderful movies about space exploration are nearly suitable for kids (or suitable for some kids) including From the Earth to the Moon, but we haven't watched any yet.

You might also search around for NASA installations or research centers in a days driving radius. In traveling recently I've come across several that I wasn't aware existed, and they all had programs and tours for visitors

Dehe, can you say suggest some space/solar system apps? or post them to the iPad app thread of a few days ago? smile
