My husband, Tom HIll, is a scientist - he studies Jupiter and Saturn and is on the Cassini team. We met in graduate school at Rice. Many women scientists are married to other scientists. The converse is not the case - there aren't enough women scientists to go around!
Both my parents were medical doctors, which certainly is a science! My father's brother was a rocket engineer at White Sands... he was truly a "rocket scientist"!
My niece and my son both got engineering degrees, so we have some scientists in the younger generation too.
As for second jobs, I do have a company that sells and installs portable planetariums. We got a Cooperative Agreement from NASA to create the technology, and now we market the domes around the world. We have over 100 installations in 25 countries and 25 states. I don't get a salary from it, though... I do it for the love of teaching people. My company websites are discoverydome.com and spaceupdate.com
