Commands: Press "W" to engage the main rocket engine, and use "Q" and "E" to rotate the rocket using the RCS (Reaction Control System).
Use the middle mouse button to recenter the camera, the left mouse button to delete an object, press "T" to switch between RCS modes (from rotation to translation), and use the left mouse button to fire the weapon (the one with orange details).
the small triangular object is an RCS (Reaction Control System) used for rotating the spacecraft, while the block labeled with "M" is the monopropellant container. The RCS requires monopropellant to function properly.
