-Re: status of Landsat 4 & 5: Landsat 4 is in "power-down" mode. From
the start, this satellite had power problems affecting it's ability to
acquire TM data so most LS-4 data is MSS. There has been talk, since
the failure of the LS-6 launch, of a Space Shuttle mission to bring
LS-4 down for repair (don't hold your breath). LS-5 is still
functioning, but  is in "as needed" status (i.e.: not collecting data
regularly, but used as needed for things like Gulf War coverage,
disasters, etc.) to prolong it's lifespan. Who knows what the future
will bring for the Landsat program.
