A lot.
My mom was a microbiology major, but decided to be a stay at home mom. However, she was a gifted musician; pipe organist, pianist, and singer. She would substitute at our large church in Houston and also play for weddings. She was also a rehearsal accompanist for the Palo Alto Children's Theatre (of which I was a part) and a singer in the Peninsula Bach Choir.
My dad was involved in infrared astronomy and later became a Mission Director on the Kuiper Airborne Observatory, based out of Moffett Field, CA. I remember that he would tell us take-off time, and we'd go to the end of our cul-de-sac, and see and hear this beautiful converted C141 painted in NASA colors climb for its usual 10 hour flight with astronomers onboard. Many important discoveries were made on the KAO including rings of Uranus, atmosphere of Pluto, and Supernova (full page picture of my dad at computer in Natl. Geographic in early 80's). My dad retired from NASA and is credited with naming the successor to the KAO- SOFIA( Stratospheric Observatory for Infrared Astronomy).
**As a post script...many years ago when on my way to San Jose Airport to return home after my dad's memorial service, we drove past Moffett on the 101. Guess what was parked next to it's old hanger...the Kuiper. Talk about tears and believing in signs from above. Heard a rumor that it may be sent to the "Boneyard" at Davis-Monthan, but do not know.
