Japan to launch i-Ball atmospheric re-entry monitoring system

The video discusses Japan's HTV 3, an unmanned spacecraft scheduled to deliver supplies to the International Space Station on July 21. After completing its mission, HTV 3 will reenter Earth's atmosphere and burn up. During reentry, an eyeball will follow the spacecraft, capturing photos and recording data, which will be sent via satellite to Mission Control in Japan.

What will the eyeball do in relation to the HTV 3?

How will the data from the HTV 3's reentry be communicated?
