Thank You Nathan...I now have access the the NASA WMS in openlayers!
Any idea on how I would use the downloaded data pack in openlayers? Is that
possible?

For using the World Wind WMS layers you referenced this is what you would
add to your map assuming that you are using the default projection for
OpenLayers (EPSG:4326)

var nasa = new OpenLayers.Layer.WMS("NASA WMS Service",
"http://onearth.jpl.nasa.gov/wms.cgi?";,
{
layers: 'global_mosaic'
, styles: 'visual'
},
{
tileSize: new OpenLayers.Size(512,512)
}
);
map.addLayer(nasa);
In the link you posted go to the "GetTileService" When you view the XML
take note of the comments in the TilePattern tags. For example:
request=GetMap&layers=daily_afternoon&srs=EPSG:4326&format=image/jpeg&styles=visual&width=512&height=512&bbox=-180,-166,76,90
In the above example you would take layers=daily_afternoon and use the
daily_afternoon as your layers in the OpenLayers definition. Styles is
not necessary unless you are looking for a specific theme. If so look in
the above example string again and you will see styles=visual, visual is
what you would specify in the styles definition for OpenLayers. Be sure
you use the tileSize definition that matches the width and height from
the TilePattern string.
The WorldWind example you reference is accessing the remote WorldWind
server for the tiles. It is not intended for accessing a copy of the data
that you downloaded.

I have 2 questions:
1. Is it possible to show World Wind WMS Layers from OpenLayers as in
http://onearth.jpl.nasa.gov/tiled.html?
I can hit their wms from my browser:
http://wms.jpl.nasa.gov/wms.cgi?request=GetMap&layers=global_mosaic&srs=EPSG:4326&format=image/jpeg&styles=visual&width=512&height=512&bbox=-180,-166,76,90
but can't seem to connect to it using any of the openlayers.layer.classes.
2. I also downloaded the NLT Landsat 7 Visible Color-Level 0 cache pack
from http://www.worldwinddata.com/
How do I use OpenLayers.Layer.WorldWind to show that layer? I looked at
http://openlayers.org/dev/examples/worldwind.html but was even more
confused after looking at that page's source.
The cache pack uzipped to my harddrive as a folder entitled '0';
subfolders entitled '0015' through '0075'; and then images such
as '0015_0046.jpg'
Thanks,
Matt
