IR camera and polarized filter for mars-suit(A proposal to add infrared vision used by player when it's too dark, that would use EVA-suit power and would be activated by "N" button...and a polarized filter that is used when it's to bright when the Sun is at zenith, activated by "M" button, that doesn't use power)

On EVA-suits helmet there are a fiew interesting things, like: 4 lights, a camera and a filter.
We have the ability to turn-on the suit's light by pressing CTRL+L.
(BTW: The light doesn't oryginate from anywhere on EVA-s suit. It's just there around the player. There should be 4 lights on EVA-suit helmet that changes texture to glowing when player activates the light).
What I propose is to add the other two functions (that BTW are used by astronauts on ISS today)
The first one: InfraRed/Night Vision Camera is used when it's too dark or when ther's a dust storm. It allows you to see a bit further in those conditions. IR camera uses power from the suit, but it's worth it.
The view when IR camera is activated may look like this: http://www.google.pl/url?source=imgres&ct=img&q=http://farm1.static.flickr.com/1/297081_473fde9522.jpg&sa=X&ei=7CnsTNjpFs2dOpes5MgB&ved=0CAQQ8wc&usg=AFQjCNFcCdqbfYB3jso-izq2cvyGWjAefQ (http://www.google.pl/url?source=imgres&ct=img&q=http://farm1.static.flickr.com/1/297081_473fde9522.jpg&sa=X&ei=7CnsTNjpFs2dOpes5MgB&ved=0CAQQ8wc&usg=AFQjCNFcCdqbfYB3jso-izq2cvyGWjAefQ)

A demonstration unit, the EVA IR Camera, shown here in use by an astronaut, is a developmental piece of hardware used by an astronaut outside the shuttle to locate damage to the Space Shuttle exterior using infrared technology. This was a joint effort between NASA Goddard and NASA Langley Research Center.

The same would go with the polarization filter. Becouse mars has a small atmosphere, when sun is reaching zenith it can get very bright - just like in orbit. Astronauts don't look stright at the Sun - they cover they'r helmet with a polaryzation filter, that make's the light dimmer.
