When will I be able to use 'Set as Target' in career mode?

[deinemuttr]

I'm playing career on normal and accepted a first rescue mission.

Since this requires a rendezvous I'm having trouble because without any tools all I can do to meet the lost Kerbal is guessing how to adjust my orbit..

Thanks in advance

Hi deinemuttr, you can upgrade your tracking station and mission control, or try the rendezvous guide in my signature below, it's very useful for this sort of thing

You just need a higher or lower orbit, a few tens of KM difference is fine, then wait till your target gets within range, raise/lower your orbit to match and wait.
