@Frank Eory: to add a little more, in the teams I managed/led, the project manager was also the scribe and didn't miss any design review or concept meetings. We made efficient use of mind maps that captured all ideas, comments, inputs in a clear and structured way. MP Divakar

Concerning the battery, as David mentioned, I did cover the failure, but as to the lesson learned, I do write about it in Part 2 of Lessons Learned (stay tuned).

Concerning the uplink antenna, if you saw it in person you'd see that it is a very robust design. We are still trying to figure it out. Personally, I don't think we'll ever know what happened to the antenna. Thankfully the uplink works.

The idea of a scribe is a good one, and I agree it is not a collateral duty. Unfortunately, most project teams don't have the luxury of dedicating a resource solely to that task.

Steve did cover this pretty well in response to my questions in an earlier entry: http://www.eetimes.com/electronics-blogs/chips-in-space/4219183/Chips-in-Space--Let-s-look-inside-ARISSat-1--part-2- But I would agree such an early battery failure is not good. Steve, any comments on the antenna failure pre-deployment? Would you do anything differently there? That said, I have worked with the type of antenna you describe and they are usually pretty rugged.

I thought there would be at least a mention of the battery that didn't work? That sounded pretty embarrassing to me.

Hi Steve, thank you for sharing the lessons learned. Surely it helps us in getting wiser :). Documenting the minutes of every meeting is a tough job but if it is done, surely it helps a lot later, saves lot of time for not re-doing the same discussions. Any lessons learned from: ARISat-I worked fine even after one antenna was found broken? :)
