ExHAM feature JMX-2015432 ExHAM feature
◆ExHAM provides easier and more frequent opportunities for small sized technical demonstrations or experiments.
◆Examples • Material exposure • Capture of space debris/aerosols • Small device test
9 JMX-2015432 ExHAM feature New concept experiment tool. ExHAM What is ExHAM? ExHAM is “Exposed experiment Handrail Attachment Mechanism” Deploy small sized samples on the Exposed area of Kibo outside the cabin area. How to use ? Prepare your samples on the ExHAM inside the ISS. Transfer ExHAM with the samples to the exposed area through the JEM airlock Install it to the handrail on JEM exterior by the JEMRMS small fine arm. 10 JMX-2015432 Steps for satellites development

Mission Example 【Mission Example : Solar Sail】 JMX-2015432 Space Environment Exposure Test of Functional Thin Film Devices for Future Solar Sail Mission
Solar Power Sail IKAROS -World’s First Solar Power Sail (2010) A novel spacecraft with hybrid propulsion of large-area solar sail and electric propulsion driven by thin-film solar cells on the sail. Future Solar Power Sail Mission
Contribute to the design Thin-film Solar Cell of future space missions
Reflectivity Control Device ISS/JEM Reinforcing Tape Exposure Test
Compare the data of IKAROS with a ExHAM sample exposure & return experiment Sample
This experiment evaluates the effects of space environment exposure on thin film solar cells and other functional thin-film devices which constitute "solar power sail" proposed for future deep space exploration. By comparing with the flight data of the world’s solar power sail demonstrator "IKAROS", the results of evaluation of the recovered samples will contribute to the development of functional thin film devices for future space missions. 【Mission Example : CFRP Mirror】 JMX-2015432 Space Environmental Testing of Lightweight and High-Precision Carbon Composite Mirrors
Carbon Composite Mirror Lightweight and high-precision CFRP replicated mirrors will contribute to development of the antennas and telescopes of next generation‘s astronomical and earth observation satellites. Most importantly, carbonFuture fiber Solar composites Power can be designed with near zero CTE(Coefficient of thermal expansion). Carbon Composite Mirror Sail Mission (Sample) Four type of carbon composite mirrors: Contribute to the lightweight and high- 1) Aluminum vapor deposition surface precision design of future space telescopes type and antenna 2) Aluminum vapor deposition surface with four-dividedReflectivity combination Control Device ISS/JEM 3) Aluminum adhesion surface type Reinforcing Tape Exposure Test 4) Aluminum thermal spraying surface type Future Mission : Submillimeter-wave atmospheric emission sounder for the future Japanese mars exploration orbiter Compare the data of ground ExHAM environmental tests with a sample exposure & return experiment Sample
This experiment studies the deterioration and the long-term effect of the CFRP replicated mirrors when they are exposed to the complex space environment. In order to realize the lightweight and high-precision CFRP replicated mirrors applicable in the wavelengths from submillimeter to optical in space, it is necessary to be exposed over a long period in space, to determine the degradation and stability of the material.
