deployment feature is put overboard through the airlock. The robot arm
grabs the deployment feature, set the position and deploy the
The deployed satellites reenter about 100 days.

Now, JAXA put out a call for Japanse satellites to demonstrate this
new system. The satellite is 1U, 2U or 3U CubeSat. Total size is 4U.
Tow to four satellites will be selected (eg 1U+3U, 1Ux2+2U, 1Ux4).

Here is the demonstration plan
  May 2011: satellites selection
  May 2012: deliver satellites to JAXA
  Sep 2012 or later: deployment using the new system

The new system will relax vibration test condition compared to rocket
launch. This will be good news for satellite manufactures.
The new deployment system will make much satellite launch chances.
