Today's science activities aboard the International Space Station are looking to improve cancer therapies and benefit cement processing on Earth. Meanwhile, two astronauts are practicing to capture the SpaceX Dragon cargo craft next week.

Cancer research in space can unlock positive benefits that are cloaked by Earth's gravity possibly leading to advanced therapies. Flight Engineer Serena Auñón-Chancellor is preparing for the Angiex Cancer Therapy experiment which will be delivered aboard the SpaceX Dragon. She is setting up the Microgravity Science Glovebox for the study that may lead to safer, more effective vascular-targeted drugs without animal testing.

Flight Engineer Ricky Arnold mixed cement samples today for stowage and future analysis on Earth. Studying how cement reacts in space during the hardening process may help engineers better understand its microstructure and material properties. Observations could improve cement processing techniques on Earth and lead to the design of safer, lightweight space habitats.

Arnold will lead Monday morning's capture of the SpaceX Dragon when he commands the Canadarm2 to grapple the space freighter Monday at 7 a.m. EDT. Commander Drew Feustel will back him up in the Cupola monitoring its approach and rendezvous. The duo set up the Cupola today and practiced the robotic maneuvers they will use to capture Dragon when it reaches a point about 10 meters from the station.

NASA TV begins its live broadcast Friday at 5:15 a.m. EDT of Dragon's launch aboard the SpaceX Falcon 9 rocket. Dragon will blast off at 5:42 a.m. from the Kennedy Space Center on a three-day trip to the orbital lab carrying almost six thousand pounds of new science experiments, crew supplies and space station hardware. NASA TV will be back on the air Monday at 5:30 a.m. covering Dragon's approach and rendezvous and again at 9 a.m. for Dragon's installation to the Harmony module.

On-Orbit Status Report

Umbilical Interface Assembly (UIA) Remove and Replace (R&R) Troubleshooting: During the UIA R&R yesterday, the crew noted that the Oxygen (O2) Supply line was approximately 2-3 mm too short to be properly mate without applying a tensile, stretching force to make contact. Initial troubleshooting was unsuccessful, and the O2 line was left partially connected and bagged against Foreign Object Debris (FOD) overnight while engineering evaluated the forward plan. This morning, the crew investigated if loosening the 20 fasteners securing the UIA to the Airlock mounting bracket would generate any free play and allow the crew to take up the gap; unfortunately, the crew indicated the tolerances were too tight and this was not possible. The crew alternatively investigated various tool configurations needed to remove the O2 Supply Line from the bulkhead in support of a backup plan to install a longer, alternate oxygen line. Engineering teams continue to evaluate pictures taken during today's troubleshooting and are working additional procedures for the crew's UIA activities tomorrow.

Atomization: The crew replaced sample syringes for the Atomization investigation today. The Atomization experiment investigates the disintegration processes of a low-speed water jet for various jet issue conditions in the JEM to validate the new atomization concept by observing the process using a high-speed camera. The knowledge gained can be applied to improve various engines utilizing spray combustion.

Microgravity Investigation of Cement Solidification (MICS) 3: The crew transferred a MICS 3 ampoule kit to the ISS Portable Glovebag and broke the seal between the upper and center ampoules in each of the two sample bags and mixed the contents in the ampoules with a spatula. Later today, the crew broke the seal between the center and lower ampoules in each sample bag and pushed the alcohol in the lower ampoule to cover the hardened cement sample. They then returned each sample bag to the kit bag and stowed them for return. The MICS investigation supports the evaluation of microstructure and material properties of benchmark cement samples. Different responses to thermal and mechanical loading are expected and will be characterized in detail. Positive attributes found in the hardening process due to the microgravity environment aboard the ISS will be reported with the intent of improving Earth-based cement and concrete processing.

Angiex Cancer Therapy: The crew completed configuration of the Microgravity Science Glovebox (MSG) Life Science hardware and the Space Automated Bioproduct Lab (SABL) CO2 meter today for the Angiex Cancer Therapy investigation. The remaining steps will be completed prior to the investigation's operations that are scheduled to start after arrival of samples on the SpaceX-15 vehicle. The Angiex Cancer Therapy investigation examines whether endothelial cells cultured in microgravity represent a valid in vitro model to test effects of vascular-targeted agents on normal blood vessels. Angiex has developed a treatment that targets both tumor cells and vasculature, but needs a better model on which to test it. This study may facilitate development of a cost-effective method that does not require animal testing and which may help develop safer and more effective vascular-targeted drugs.

MagVector 3D: The crew changed MagVector 3D samples today. A total of 12 different samples will be processed on the ISS (1 per day). ESA's MagVector investigation supports a study of how Earth's magnetic field interacts with an electrical conductor. Using extremely sensitive magnetic sensors placed around and above a conductor, researchers can gain insight into ways that the magnetic field influences how conductors work. This research is expected to help improve future ISS experiments and electrical experiments, and could also offer insights into how magnetic fields influence electrical conductors in general.

Team Task Switching (TTS): A crewmember completed a TTS survey today. When crewmembers are often required to switch their attention between tasks, performance on each of the tasks can be affected. The objective of the TTS investigation is to gain knowledge about whether or not crewmembers have difficulty in switching tasks and determine the impacts of these switches, in order to both reduce any negative consequences and improve individual and team motivation and effectiveness.

PAO Event: This afternoon Serena Aunon-Chancellor participated in and event with the Smithsonian Air and Space Museum Washington, D.C. The audience for this event are students who participated in the Future Engineers "Two for the Crew" Challenge and middle school students from the local DC area.

Dragon Off-Set Grapple Training: During this afternoon's training session, the crew practiced grapple approaches with the Space Station Remote Manipulator System (SSRMS) using the Permanent Multipurpose Module (PMM) Flight Releasable Grapple Fixture (FRGF) as the target. They maneuvered SSRMS over the pin and practiced pulling the trigger when they were in the grapple envelope; since no Latching End Effector (LEE) commands were loaded, no mechanism motion was initiated upon the trigger pulls. Today's session gave the crew an opportunity to assess the Robotics Worksite in the Cupola and determine how to best manage the volumetric constraints in the Cupola prior to capture day.

Cupola Window 7 Vacuum Line Cover Taping: Today the crew performed a procedure to tape the Cupola Window 7 metal vacuum line closeout cover with Glass Cloth Tape and completed a photo survey of the Cupola Nomex Closeouts in the Cupola to document UV degradation. Earlier this year, the crew reported a softgood cover located in the Cupola was substantially faded and beginning to fall apart. This condition is most likely caused by Ultraviolet (UV) exposure through the Cupola Windows. The primary near-term concern is that the metal vacuum line closeout below the fabric cover is nickel-plated aluminum and presents a possible touch temperature hazard when exposed to direct sunlight.

SpaceX-15 Cargo Prepack: Today the crew started the approximately 10 hours of Dragon Cargo Prepack in order to stage equipment and bags slated for return on SpaceX-15 Dragon. Dragon is scheduled to launch on Friday, 29 July with berthing on 2 July.
