Coolest birthday card ever

Last week, I received what is most likely the coolest birthday card of my life from my friend Chantal Darquenne, who is a NASA researcher and adjunct professor at UCSD (San Diego, CA).

Chantal's work involves lots of zero-gravity experiments. While some of these experiments were conducted by John Glenn himself during his 1998 space shuttle mission, most are performed through huge series of parabolic flights in a specially equipped NASA plane (A 707 if I remember correctly).

She was above Florida in her giant roller coaster again last week when her colleague took this great picture :

In case you don't believe she's floating, read the gravity indicator on the ceiling ;-)
So cool! Thanks so much, Chandechan!
