jsc2019e041776 (10/2/2012) --- A preflight phase contrast image of vascular endothelial cells cultured on microcarrier beads before being put into the flight hardware. Used for STaARS BioScience-3 experiment. The Spaceflight Effects on Vascular Endothelial and Smooth Muscle Cell Process (STaARS BioScience-3) investigation contributes to a greater understanding of cardiovascular disease (CVD) through the study of transcriptomics of vascular cells. Upon return from spaceflight, crew members often display alterations in their cardiovascular systems, similar to those suffering from CVD. The goal of this work is to elucidate the mechanism of vascular cell damage in the space environment by exposing vascular cells to spaceflight.

Launched on June 20, 1996, the STS-78 mission’s primary payload was the Life and Microgravity Spacelab (LMS), which was managed by the Marshall Space Flight Center (MSFC). During the 17 day space flight, the crew conducted a diverse slate of experiments divided into a mix of life science and microgravity investigations. In a manner very similar to future International Space Station operations, LMS researchers from the United States and their European counterparts shared resources such as crew time and equipment. Five space agencies (NASA/USA, European Space Agency/Europe (ESA), French Space Agency/France, Canadian Space Agency /Canada, and Italian Space Agency/Italy) along with research scientists from 10 countries worked together on the design, development and construction of the LMS. This photo shows the LMS being installed in the payload bay of the orbiter Columbia during preflight preparations.

S73-26380 (23 May 1973) --- Technicians in the Technical Services shop in Building 10 work on the fabrication of the umbrella-like mechanical device called the “parasol” during Skylab 2 preflight preparations at NASA's Johnson Space Center. Here, they are attaching the telescoping extension rods to the canopy. The “parasol” is designed to fit into the TO27 experiment photometer canister. The canopy is 24 feet by 22 feet. The sunshade device will be deployed through the solar scientific airlock in the side of the OWS. The “parasol” solar shield is considered the prime possibility for use as the OWS sunshade because it will not require EVA by the Skylab 2 crewmen, because of the operational ease of using it, and because of the simplicity of the device which minimizes crew training.

KENNEDY SPACE CENTER, FLA. - Flags are flying on Launch Pad 39B at NASA Kennedy Space Center as Space Shuttle Discovery is ready on the pad for launch after rollback of the Rotating Service Structure. Rollback of the RSS is a major preflight milestone, typically occurring during the T-11-hour hold on L-1 (the day before launch). Discovery is scheduled to lift off on the historic Return to Flight mission STS-114 at 10:39 a.m. EDT July 26 with a crew of seven. On the mission to the International Space Station the crew will perform inspections on orbit for the first time of all of the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wings and the Thermal Protection System tiles using the new Canadian-built Orbiter Boom Sensor System and the data from 176 impact and temperature sensors. Mission Specialists will also practice repair techniques on RCC and tile samples during a spacewalk in the payload bay. During two additional spacewalks, the crew will install the External Stowage Platform-2, equipped with spare part assemblies, and a replacement Control Moment Gyroscope contained in the Lightweight Multi-Purpose Experiment Support Structure.
