A student experiment — successfully flown up and down to ISS by Dragon — is apparently a failure because no one on ISS ever turned it on.
Per instructions from NanoRacks, the Houston company that works with NASA to integrate such deliveries, Warren packed his worms, or C. elegans, into a glass ampule, or tube, then packed that tube into a larger one containing a liquid “growth medium” for the worms. An astronaut aboard the space station was to crack the outer ampule in a way that would release the worms into the surrounding liquid. It never happened.
The article is very diplomatic about this, but it is very clear that either the astronauts on ISS screwed up, or NASA did by not giving them clear instructions.
