There seems to be no indicator in the HUD to show the player where he is looking.

This was uncomfortable to me when using landers. Sometimes I was not able to take a photo of a required spot to finish a mission. I would have rather send a second (small) lander in that direction to take the photo. It is very difficult to determine the direction you are looking to when in the middle of a crate...

I would like to suggest to add an indicator of where you are looking (north, west, south, east). This would make it much more easy to determine where to send your second lander to get behind that hill that blocks your line of sight for the final photo...
