<DIV><SPAN class=381241515-17022005><FONT face=Arial color=#0000ff size=2>I'd
like to suggest in the "Types of communication" area traffic that would assist
astronauts during EVAs. As we discussed previously outside of this mailing
list, it has been envisioned that astronauts in the next decade will have
some type of either wearable computer (perhaps in the form of the work done at
MIT <A
href="http://web.media.mit.edu/~schwartz/wearsat/">http://web.media.mit.edu/~schwartz/wearsat/</A>)
or some other form of data assistant. Earth-based data sources could then
be queried or data pushed to the astronauts during their work thereby reducing
the high level of voice comms typical of astronaut EVAs. Also, it might be
beneficial to include data examples such as email not only because one can
assume it's likely astronauts would need it both operationally as well as for
their welfare, but also because it's a scenario that is common to what people do
on Earth and thus is easy to relay to those interested in the
architecture.</FONT></SPAN></DIV>

<DIV><SPAN class=237275414-11022005><FONT face=Arial size=2>Here's my first
cut at a scenario for going to to the moon. Right now I've just got a
list of players and a rough storyboard, but hopefully these can provide a
skeleton to hang the rest on.</FONT></SPAN></DIV>

<DIV><SPAN class=237275414-11022005><FONT face=Arial size=2>I think a good
next step in fleshing this out would be to identify some technologies
that could be used (e.g. CCSDS AOS links from Earth to Crew while in transit
to the moon, 802.11g between crew capsule and astronaut suits,
etc.)</FONT></SPAN></DIV>
