Space station astronauts take second spacewalk

The video tutorial covers the egress of crew members from the Pirs docking compartment and their initial task of installing a docking compartment on the zenith port of the service module. It includes a view from Oleg Kononenko's helmet camera and shows Commander Sergei Volkov configuring a camera. The crew then relocates the Yakor foot restraint, previously used on a spacewalk, to the end of the Strela boom. Throughout the activities, the flight control teams in Houston and Moscow provide support and monitor the crew's progress.

What support is being provided by the flight control room in Houston and the Mission Control Center in Moscow?
