  Title: STS-56 color infrared Earth observation of northern Argentina
  Description:
  STS-56 color infrared Earth observation taken aboard Discovery, Orbiter 
  Vehicle (OV) 103, shows the agricultural frontier (rectangular field 
  patterns) impinging on the natural grasslands (pampas) of northern
  Argentina.  Note the sharp delineation between the upland agricultural
  areas (red and  pink rectangles), and the lowland semi-arid grasslands or
  pampas (shown in  violet and purple).  In addition, several large smoke
  plumes associated with  biomass burning are visible.  These smoke plumes
  and their burn point sources  are considered to be evident of extended
  agricultural preparations in the  lowland pampas.
