Space Station Science Highlights: Week of June 25, 2018

ISS - Expedition 56 Mission patch.

July 1,2018

This week aboard the International Space Station, crew members of Expedition 56 initiated a number of new scientific investigations and continued work on many others.

The crew also staged equipment and bags slated for return on the SpaceX-15 Dragon, which launched to the space station on Friday, June 29, and is scheduled to berth on July 2.

Launching little satellites

This week, the crew installed a NanoRacks CubeSat Deployer (NRCSD) on the Multipurpose Experiment Platform (MPEP) in preparation for its use, targeted for the week of July 9. Each NRCSD accommodates up to 6.5 Units (one unit, or 1U, measures 10x10x10 centimeters) and eight launch cases, which are ejected through the Japanese Experiment Module (JEM) Airlock. NRCSDs meet the growing demand to deploy CubeSat nanosatellites for a variety of customers.

This deployment, NRCSD-14, includes nine CubeSats: RainCube, Radix, CubeRRT, HaloSat, TEMPEST-D, EnduroSat AD, EQUISat, MemSat and RadSat-g.

Watching water jets break up

The crew replaced sample syringes in the JEM for the Japanese Space Agency (JAXA) Atomization investigation this week.

This experiment uses a high-speed camera to observe the disintegration processes of low-speed water jets under various conditions. These observations validate a new atomization concept, developed from drop tower experiments on Earth, to correctly predict the breakup positions of a liquid stream. This information is key to improving spray combustion processes inside rocket and jet engines.

Space station turns concrete mixer

For the first of eight sessions of Microgravity Investigation of Cement Solidification (MICS), the crew transferred a MICS 3 ampoule kit to the Portable Glovebag, broke the seals and mixed the contents of the upper and center ampoules. Later, crew mixed the center and lower ampoules in each sample bag, then pushed alcohol in the lower ampoule to cover the hardened cement samples. Each sample bag was returned to the kit bag and stowed for return.

MICS supports evaluation of microstructure and material properties of benchmark cement samples, characterizing in detail different responses to thermal and mechanical loading.  Positive attributes found in the hardening process due to the microgravity environment may help improve cement and concrete processing on Earth.

Navigating in the stars, with the stars

Crew conducted operations for the Sextant Navigation investigation, which tests use of a hand-held sextant as emergency navigation for future space vehicles such as Orion. Sextants have a small telescope-like optical sight to take precise angle measurements between pairs of stars, enabling navigation without computer assistance. Crewmembers test specific techniques, focusing on stability, for using this tool in space.

Image above: “Nothing beats waking up on a technological marvel and then starting the day off with an antique method of navigating. Sextant Operations from @Space_Station! Still considered a potential backup method of navigation for future vehicles…” said NASA astronaut Serena M. Auñón-Chancellor on her Twitter, @AstroSerena. Image Credit: NASA.

Other work was done on these investigations: SPHERES, Airway Monitoring, CIR/ACME, Time, Lighting Effects, CEO, ASIM, SUBSA, Area PADLES, Veggie/PONDS, HDEV,  Marrow, Vascular Echo, Functional Immune, Probiotics, STaARS BioScience-9, Multi-Omics, MagVector, Team Task Switching and CAL.
