I'm a but emberaced to ask it, but what is a RHS? the ''joystick''
During the beginning of space era there were a lot of tests and training was tough from a physical point of view.
Which one of those tests and training exercises still prevail for real astronauts?
1: There's a series vents along the body of the orbiter which is used to equalize the pressure between the orbiter and the outside.
2: See 1. The vents are closed shortly before the de-orbit burn to protect against plasma intrusion. They open again later during the descent.
As I wrote: the vents are used to equalize the pressure between the outside and various compartments. So on-orbit, the bay is already at vaccum before the doors are opened. Same thing with the aft compartment.They are opened or closed, but are they pressurized? I figure out they are. Are they?

No. The vents are commanded to the full open position shortly before launch. During launch the air inside the various compartments is vented overboard through the vents to equalize the pressure.That brings another question.
Are ascent calculations considering the loss of air inside the cargo bay?
If air is inside during ascent, it means more mass needs to be pushed by the engines. Since aerodynamic airflow implies lower pressures, does it complicate calculations?
