I have also heard of people who could finish them in only the current Grade 6 stuff, or at most with 1 or 2 Grade 7 things they bought with saved Fleet Comms.
So really, this is just a practice issue for you I think.
Well yes, I got the best gear prior to the new stuff on my spaceship and I can't do the most difficult spacemissions. But I have several friends who can do them with much worse gear on their ships, I've seen them do it when over for dinner and such things. I'm just not good enough at keeping my ship moving around during flying. So yeah, having the best gear is no guarantee that you will be able to make the missions.
