ISS036-E-020935 (17 July 2013) --- NASA astronaut Karen Nyberg, Expedition 36 flight engineer, works to setup the Multi-Purpose Small Payload Rack (MSPR) fluorescence microscope in the Kibo laboratory of the International Space Station. This configuration, along with the leak checks that the crew performed in June, is in preparation for the Aniso Tubule experiment launching on HTV-4 in August. Aniso Tubule will investigate the role of cortical microtubules and microtubule-associated proteins in plant growth while in microgravity.

ISS036-E-017393 (8 July 2013) --- NASA astronaut Chris Cassidy (left) and European Space Agency astronaut Luca Parmitano, both Expedition 36 flight engineers, are pictured in the Quest airlock of the International Space Station as they prepare for the start of a session of extravehicular activity (EVA). Cassidy and Parmitano are wearing Extravehicular Mobility Unit (EMU) spacesuits. NASA astronaut Karen Nyberg, flight engineer, assists her crew members.

ISS036-E-005534 (31 May 2013) --- When off-duty time comes for crew members aboard the Earth-orbiting International Space Station, astronauts often like to take advantage of the micro-gravity to do things that they can't do on Earth, such as hang upside down or suspend fruit in air. Here, Flight Engineers Karen Nyberg of NASA and Luca Parmitano of the European Space Agency find a spot in the Unity node to their liking for a brief recess.

ISS036-E-035767 (18 Aug. 2013) --- NASA astronaut Karen Nyberg, Expedition 36 flight engineer, works with new test samples for the Advanced Colloids Experiment, or ACE, housed in the Light Microscopy Module (LMM) inside the Fluids Integrated Rack of the International Space Station?s Destiny laboratory. Results from ACE will help researchers understand how to optimize stabilizers to extend the shelf life of products like laundry detergent, paint, ketchup and even salad dressing.

ISS036-E-017438 (8 July 2013) --- NASA astronaut Karen Nyberg, Expedition 36 flight engineer, speaks into a microphone in the International Space Station’s Quest airlock while the crew prepares for a July 9 session of extravehicular activity (EVA) with NASA astronaut Chris Cassidy and European Space Agency astronaut Luca Parmitano, both flight engineers.

ISS036-E-014724 (3 July 2013) --- NASA astronaut Chris Cassidy (left) and European Space Agency astronaut Luca Parmitano, both Expedition 36 flight engineers, attired in their Extravehicular Mobility Unit (EMU) spacesuits, participate in a ?dry run? in the International Space Station?s Quest airlock in preparation for the first of two sessions of extravehicular (EVA) scheduled for July 9 and July 16. NASA astronaut Karen Nyberg, flight engineer, assists Cassidy and Parmitano.

ISS037-E-004972 (27 Sept. 2013) --- Seen floating on the Cupola of the Earth-orbiting International Space Station, this quilt block, paying tribute to the state of Texas or the Lone Star state, was fashioned from T-shirts onboard the orbital outpost by Expedition 37 Flight Engineer Karen Nyberg. The NASA astronaut has spent much of her off-duty time on the station sewing and fashioning various items, using only a handful of tools she took aboard and whatever materials that have been available.
