Facility Description

Facility Overview

The Multipurpose Small Payload Rack (MSPR) consists of the following:
 
Work Volume (WV)
A workspace for the experiments, such as Aquatic Habitat experiments and the combustion experiments. The WV also accommodates other equipment for science and educational missions within its function. The WV contains a Nitrogen gas supply and an exhaust line. Its dimensions are 600 mm(H) x 900 mm(W) x 700 mm(D), and has 350L of volume.
 
Small Experiment Area
(SEA) A volume for small size experiments that do not need many resources such as crystallization experiments. Vibration isolation from WV and crew can also be accommodated. Its dimensions are 300 mm(H) x 411 mm(W) x 529 mm(D), and has a volume of 70L.
 
The WV and SEA also provide the following capabilities:
  • Heat rejection, smoke detection of the user’s equipment.
  • Emergency power supply cutoff.
  • Management of noise and emissions generated from user’s equipment for crew safety.
Workbench (WB)
A work table for crews maintaining user’s equipment, exchanging samples and reviewing data. Its area is about 0.5m2. The WB is the only work table in the JEM and can be stored into the rack when it is not in use. Power for LAPTOP PC is also available. The MSPR also contains a double enclosed chamber for combustion and other experiments that require enclosed and/or exhaust systems in the JEM. It can be set up into WV. User area dimensions are 520mm(H) x 550mm(W) x 354mm(D).
 
Power
Supplied interfaces´╝Ü 28[VDC], 16[VDC], 5[VDC]
Power Supply:
  • WV and SEA: Total 500[W]
  • Workbench 100[W] (16[VDC] for LAPTOP PC)
Video
As MSPR, one of following is available (recorded, downlink). NTSC video x 3[ch] or High-definition television (HDTV) x 1[ch].
 
Communications
Protocol: Ethernet, USB User’s equipment ⇔ LAPTOP PC, LAPTOP PC ⇔ Users on the ground.

Operations

Facility Operations

  • Transported inside the Japanese Experiment Module (JEM) to orbit with sub-rack facilities.
  • Checkout of MSPR is performed following transfer and installation into the Japanese Experiment Module (JEM) Pressurized Module (PM), Kibo, on the International Space Station.
