Following a week of successful science operations on the experiment for the Roll-Out Solar Array (ROSA), attempts to retract and latch the array were unsuccessful. The ISS Mission Management Team met Monday morning and made the decision to jettison ROSA directly from its current location at the end of the space station’s robotic arm, where it was fully deployed in a normal configuration. The original plan called for ROSA to be stored back inside the trunk of SpaceX’s Dragon which is detached and burned up in the atmosphere during Dragon reentry. The Operations team executed the jettison procedure that was developed as part of the pre-flight planning process that covered various scenarios. ROSA will not present any risk to the International Space Station and will not impact any upcoming visiting vehicle traffic. ROSA is an experiment to test a new type of solar panel that rolls open in space and is more compact than current rigid panel designs.
