After a scrub on April 29, Endeavour launched into partly cloudy skies carrying our small vials of lysozyme/ citrate buffer and salt solution on Monday morning, May 16. Early in the day on the 17th the experiment was activated. This means that the two vials were brought into alignment, allowing the lysozyme/ citrate buffer to interact with the salt solution. We hope some protein crystals grow over the course of the 16 day flight!
