"At that point, there will be the handover between the shuttle arm and the station arm so that the shuttle arm will take the cradle and put it into the cargo bay"

This quote is referring to the procedure of docking a spacecraft to the International Space Station (ISS). The shuttle arm is a robotic arm that is connected to the ISS and is used to record and dock spacecrafts. The station arm is a robotic arm that is attached to the spacecraft and is used to move cargo from the spacecraft to the ISS. The cradle is a gadget that is connected to the station arm and is utilized to hold the cargo. When the spacecraft is close adequate to the ISS, the shuttle bus arm will extend and grab the cradle from the station arm. The shuttle arm will then move the cradle into the freight bay of the ISS, completing the handover procedure. This process is essential for the effective transfer of cargo from the spacecraft to the ISS. Without it, the cargo would not have the ability to reach the ISS.
