Why can't I select a kerbal for a rescue mission?

[ErasmoGnome]

I accepted a contract to save a little guy from his vaccuummy doom, but I can't select him to do a rendezvous. Do I need to upgrade my tracker? I've tried clicking on him, his orbit, etc, but nothing works. I can't really imagine trying to do a rendezvous without having him selected as target - so much in the process depends on the navball and intersection thingies.

You need to upgrade tracking and mission control.

If you want to wait until you're in orbit, you can use a setting in the game called "Show Vessel Labels", that'll let you click on the target further than 2.5km.

If you want some help with doing it unupgraded, I did a tutorial here:

Oh I didn't know you needed to upgrade that. Thanks!
