The issue with this is that with other dailies, theres 5-6 dailies you can do for a given area, allowing you to focus your attention on a single thing for ~1 hour. But with the space missions there is essentially 1 viable mission per day, some as short at 3 minutes, the longest like 6. So yes this makes it not that hard to do every day, but its frustrating in that you cannot really focus on concentrated space missions for a decent period of time. The day the missions first came out and I was doing the initial missions was the most fun I had had doing space missions ... ever. Overall I would much prefer if we were able to do them all at once, or at least have options to do more than one in a row on a given day. Instead I am left logging into multiple characters for 3-5 minutes a day, leaving me in a very unsatisfied and unhappy state with respect to doing space missions. If they do not change the current setup, I forsee only doing 1-2 missions a week tops. This is hardly what was seemingly promised with the new missions.

This does clarify how they work, but I have to agree with the other posters that this is extraordinarily confusing and very inconvenient. I would love to be able to collect them all and spend an hour doing them on Saturday, as it is difficult for me to log in most week days. I would suggest switching them to each be a separate weekly, resetting on different days. The net effect would be almost identical, and it would help some of the more casual players get more than 1 or 2 done per week.

They are still bugged as follows: On one character I have done all missions on the day of availability and completed them successfully, so no issues as long as they are completed every day. I will be able to test the weekly resets starting today. But on another character, I did not log in for 2 days, and as a result I am missing the missions for those two days (Thurs/Friday) for this week. It appears as if when you skip a day the mission disappears upon the next reset.
