I've noticed that too and I think the problem is on the server side. The wms_4 
test from GDAL autotest takes a big amount of time before failing : the 
returned image from the NASA JPL server is 0 byte length.

Here's the culprit WMS request :
http://onearth.jpl.nasa.gov/wms.cgi?request=GetMap&version=1.1.1&layers=modis,global_mosaic&styles=&srs=EPSG:4326&format=image/jpeg&width=1024&height=1024&bbox=-180.00000000,89.86175997,-179.86175997,90.00000000

If you modify it to only return the global_mosaic layer, the request returns 
in a few seconds, but the image is totaly black (probably OK for that part of 
the world ?).
