Exposed Experiment Handrail Attachment Mechanism (ExHAM)

Experiments can be performed in an exposed space environment by attaching it to JEM’s Exposed Facility.

 This is enabled by ExHAM, a cuboid mechanism equipped with a grapple fixture on the upper surface for the Kibo’s robotic arm, Japanese Experiment Module Remote Manipulator System Small Fine Arm grapple and attaching parts on the under surface for fixation to the handrail on the Kibo’s Exposed Facility.

The number of loadable experiment samples is 7 on the upper surface and 13 on the side surfaces. Experiment objects can be exposed for a few months or up to 3 years and then sent back to Earth for analysis.

In the past, opportunities for conducting experiments in the exposed environment was limited since it requires onboard crew’s Extravehicular Activity (EVA) for installing and retrieving the experiment equipment. Kibo’s unique facility increases experiment opportunities in the exposed environment.
