[Sis-csi] Cislunar scenario

[Krupiarz, Christopher]

Keith,
 
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
http://web.media.mit.edu/~schwartz/wearsat/) 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.
 
Chris

	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.
	 
	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.)
	 
	Comments welcome (especially additions),

	========================
	 
	Things that need to communicate:
	 
	Development / Test facilities
	Ground Network (e.g. DSN stations)
	Space Network (e.g. TDRSS)
	ISS (not sure if NASA thinks of ISS as a possible space network
relay or not)
	Launch vehicles (including 'combinations' like crew capsule +
launch vehicle when mated on the pad)
	Orbiting assets (like several different assets (crew, supplies,
booster) that need to rendezvous in orbit before proceeding to the moon)
	Astronauts in space suits doing EVAs
	Lunar landers/rovers
	Lunar orbiters
	Lunar base
	 
	---------
	 
	Mars orbiters
	Mars Landers/Rovers
	 
	 
	======== Phases of operation ============
	pre-launch:
	 
	Development / test
	 
	Launch Operations (crew, stuff may be launched separately but
coordinated)
	 
	On-Orbit rendezvous
	 
	Lunar Transit
	    Crew EVA
	 
	Land the stuff (stuff lands on moon, crew in orbit)
	 
	Land the crew (preferably near the stuff)
	    CREW EVA to set up stuff
	 
	Science Ops
	    Place remote stations
	    Operate remote vehicles / stations from base station
	    EVAs to look for interesting rocks
	 
	======= 
	 
	Types of communications:
	 
	Voice communications to astronauts.
	Continuous data comms (telemetry, health & status, low-rate
video)
	Busrsty comms (like HDTV news interviews)
