The build out of the phased array is in the budget, including testing, etc. I am sorry if that was not clear. Rick is discussing TDRS as a possibility on the ISS with out Intelsat proposal. That is only possible with a new antenna on another part of the station and it will need to be steered electrically if we are to ever use it.
If we have to fly Eagle spacecraft or just plain desire to do so, it will not be able to meet its operational goals without the phased array.

While you are looking at the plans for what we need to accomplish in 2008, I think that in the RF area we should include a physical modeling of at least the key parts of Tom Clark’s suggested phased array antenna. We need to prove the principle. We will need the RF amplifiers and distributed gain aspects of this antenna to meet our orbital RF power and directivity goals. This then demands the creation of some real hardware – getting us past the heise luft part of the design into something that can point us to what the all-up, on-orbit hardware should look like.
If this line is not examined, we then need to have a proposal for what we should pursue..... Tom’s proposal seems like a reasonable starting point. Such an project will require the efforts of a multi-technology team.
