Thanks to IIAS for expanding our official crew flight jacket options. I love sharing the story of our science missions and the work we do in space, and I also love that our daughters know that femininity or fun doesn’t undermine credibility and professionalism. It’s the same reason I always keep my friendship bracelets on. 🥹💕 #sparkle #femininestyle #girlhood #motherdaughter #motherhood #friendshipbracelets #pinkaesthetic
