jsc2023e010183 (2/28/2023) --- The High school students United with NASA to Create Hardware (HUNCH) Ball Clamp Monopod (HUNCH Ball Clamp Monopod) investigation aims to test a temporary but stable platform for holding cameras, making camera operations easier and faster for the International Space Station crew. This hardware was designed and developed by HUNCH students using engineering design processes. They produced elements such as Computer Aided Design (CAD) drawings, CAD study models, and 3D printed engineering evaluation units on parts such as this insert that allow the seat track clamp to be positioned.

KENNEDY SPACE CENTER, FLA. - In KSC's Vertical Processing Facility, Louise Kleba of the Vehicle Integration Test Team (VITT) and engineer Devin Tailor of Goddard Space Flight Center examine the Pistol Grip Tool (PGT), which was designed for use by astronauts during spacewalks. The PGT is a self-contained, micro-processor controlled, battery-powered tool. It also can be used as a nonpowered ratchet wrench. The experiences of the astronauts on the first Hubble Space Telescope (HST) servicing mission led to recommendations for this smaller, more efficient tool for precision work during spacewalks. The PGT will be used on the second HST servicing mission, STS-82. Liftoff aboard Discovery is scheduled Feb. 11.

KENNEDY SPACE CENTER, FLA. - Space Shuttle Main Engine (SSME) No. 2036, the first of the new Block 1 engines to fly, awaits installation into position one of the orbiter Discovery in Orbiter Processing Facility 2 during preparation of the spaceplane for the STS-70 mission. The advanced powerplant features a new high-pressure liquid oxygen turbopump, a two-duct powerhead, a baffleless main injector, a single-coil heat exchanger and start sequence modifications. These modifications are designed to improve both engine performance and safety.

CAPE CANAVERAL, Fla. -- At NASA's Kennedy Space Center in Florida, from the left, Leandro James of Systems Hardware Engineering, George Mizell of Quality Assurance, Morgan Simpson of Flight Hardware Processing and Kim Simpson of Fluids, Mechanical and Structural Systems prepare a parachute for a small rocket prior to launch as part of Rocket University. The goal was to test its systems and to verify that it performed as designed. As part of Rocket University, the engineers are given an opportunity to work a fast-track project to develop skills in developing spacecraft systems of the future. As NASA plans for future spaceflight programs to low-Earth orbit and beyond, teams of engineers at Kennedy are gaining experience in designing and flying launch vehicle systems on a small scale. Four teams of five to eight members from Kennedy are designing rockets complete with avionics and recovery systems. Launch operations require coordination with federal agencies, just as they would with rockets launched in support of a NASA mission. Photo credit: NASA_Jim Grossmann

View of Flight Engineer (FE) Mike Hopkins initiating a CFE-2 (Capillary Flow Experiment - 2) Interior Corner Flow - 5 (ICF-5) test run. Liquids behave differently in space than they do on Earth, so containers that can process, hold or transport them must be designed carefully to work in microgravity. The Capillary Flow Experiment-2 furthers research on wetting, which is a liquid's ability to spread across a surface, and its impact over large length scales in strange container shapes in microgravity environments. This work will improve our capabilities to quickly and accurately predict how related processes occur, and allow us to design better systems to process liquids aboard spacecraft (i.e., liquid fuel tanks, thermals fluids, and water processing for life support). Image was released by astronaut on Twitter.

iss057e106264 (Nov. 27, 2018) --- Flight Engineer Serena Auñón-Chancellor mixes samples for the Microgravity Investigation of Cement Solidification (MICS) experiment and installs them into the Multi-use Variable-g Platform. The research utilizes the microgravity environment aboard the International Space Station to investigate the complex process of cement solidification. Results may impact possible construction processes and designs for space habitats on the surface of the Moon and Mars.

In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, technicians and engineers removed protective wrapping from the ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS). ECOSTRESS is designed to monitor one of the most basic processes in living plants: the loss of water through the tiny pores in leaves. ECOSTRESS will launch to the International Space Station aboard a Dragon spacecraft launched by a Falcon 9 rocket on the SpaceX CRS-15 mission in June 2018.
