New Horizons is able to transmit to Earth at only about 2 kb/s (I might be slightly off). So right now, and for about the next week it will be sending back essentially thumbnail images (in addition to science data). These are JPEG-compressed, and during this stage will only be from the panchromatic (b&w) camera, which has a higher resolution. Later this year it will begin downlinking the full set of uncompressed, full-resolution images, including those in color. The full dataset is expected to be about 60 GB and will take about 18 months to downlink.
