Extra Vehicular Activities (EVA)

Extra Vehicular Activities (EVA) - commonly known as “Spacewalks” - are activities in which the Astronauts operate outside the spacecraft in a specially designed Space Suit that protects them and supplies the necessary life support to enable them to perform various tasks in Space.

In Space Shuttle Mission 2007, there are quite a few missions that require the player to perform various tasks in EVA in order to complete the mission.

In the game when an Astronaut is outside the Shuttle you need to select him as the tracked object in the External view (by multiple F1 Key presses). The currently active object is shown in the MET clock window, in the upper right side of the main 3D view. After the EVA is selected a First Person View is available (F3 Key), allowing the gamer to see what a real Astronaut performing EVA would see.

Tethered EVAs


The Tethered EVA is very simple to learn and understand. It is very straigforward and it is controlled with the Numpad or joystick.

Tethered EVA, First person view


With version 2.40 EVA can move now in 6DoF. The controls used to move are all located on the Numpad:

Translate Fwd/Back Numpad - / Numpad +
Translate Up/Down Numpad PgUp / Numpad PgDn
Translate L/R Numpad / / Numpad *
Roll Left/Right Numpad L Arrow / Numpad R Arrow
Pitch Up/Down Numpad Up Arrow / Numpad Dn Arrow
Yaw L/R Numpad Ins / Numpad Del
The “Num Lock” key should be turned on while in the game


Using the joystick is slightly less intuitive and sometimes the keyboard (or a combination of Numpad + joystick) would be preferable.

Forward/Aft Pitch Axis
Left/Right Roll Axis
Up/Down Yaw Axis (rudder)

Un-tethered EVAs




The Manned Maneuvering Unit is designed to allow astronauts free unrestricted work outside of their spacecraft. The MMU allow control in all the axises and movment in all three.

In SSM2007 the MMU is used in STS-41C and STS-51A.

MMU in orbit (STS-41C)


Simplified Aid for EVA Rescue has been introduced as a safe guard for tethered space walks. It is much smaller and lighter then the MMU and has a limited amount of propellant.

In SSM2007 the SAFER is used in STS-88 and STS-98.


The Un-Tethered EVA is very similar to orbital maneuvering with the shuttle. controls are the same. the MMU used a miniature version of the RHC/THC for control.


the controls used are the Numpad keys, the arrows and “Page down” and “delete” key from the “six pack”.
the Numpad controls translations while the Arrows and the “Six Pack” control attitude.


RHC (Attitude) THC (Translations)
Pitch UP/Down Arrows Forward/Aft NumPad8/NumPad2
Roll Left/Right Arrows Left/Right NumPad4/NumPad6
Yaw Delete and Page down Up/Down NumPad9/NumPad3
The “Num Lock” key should be turned on while in the game


Attitude control using a joystick is natural. Pitch, Roll are always available. YAW is usable if the joystick has a twist axis. Throttle if available should be kept in the middle of it's range (explanation in a second)

Translations with a stick are a bit more complex. to activate translations you hold down the Trigger while moving the stick around. Left, Right, Forward and Aft are available in this configuration.

Up/Down translations are controlled via the throttle. while holding down the trigger and “increasing” or “decreasing” the throttle the shuttle will translate up and down.

Some users find it easier to use the Stick for Attitude control, and the keyboard for translations.
