i-SEEP
An image of i-SEEP to which two pieces of experimental hardware are attached

The IVA-replaceable Small Exposed Experiment Platform (i-SEEP) is a hardware adapter for Kibo’s Exposed Facility (EF), to which several units of exposed experimental hardware weighing up to 200 kg and measuring up to 50 x 70 × 35 cm in size can be attached. It is a new EF platform used as an interface between the EF and exposed payloads. Through Kibo’s airlock, it allows for more frequent installation and the return of the experimental devices.

Additional Equipments as i-SEEP extension

Small Payload Support Equipment: SPySE

SPySE will be attached to i-SEEP and supports the operation of small payloads with a data interface that provides power and communication environment for small payloads in 10-30 cm size range. SPySE can carry up to eight payloads. This equipment is suitable for mounting small payloads that are difficult to mount directly on i-SEEP.

Exposed Experiment Bracket Attached on i-SEEP: ExBAS

ExBAS is one of the devices to be installed on SPySE. It is designed to integrate multiple exposure samples (up to 17) and be installed on the SPySE/i-SEEP outside the Kibo to conduct various exposure experiments. Experimental samples and small items can also be stored in the internal box. This bracket is equipped with a temperature measurement system to provide the temperature data during the exposure experiments.

Examples of Utilization

EF HDTV camera 2

Photographs of Earth will be taken using a commercial-off-the-shelf (COTS) camera for the purposes of public affairs, education, disaster observation, and demonstration of a COTS product. It is one of the two first payloads to be attached to i-SEEP.

Examples of images (images taken in past missions)

Giant swirl of a typhoon
Flood of the Amur River
Northern Japan in winter

In-orbit demonstration of the GPSR/Wheel unit

GPSR/Wheel Demo Unit

A demonstration of commercialized components to be loaded into small satellites will be performed to reduce the costs associated with satellite development. It will lead to market growth and strengthen the competitiveness of domestic parts manufacturers. It is also one of the first payloads to be attached to i-SEEP.
