Really need to supply some more info there pal.
What format are the input rasters? Ensure that the input rasters have same number of bands and same bit depth.
For Landsat 8 image inputs, you may choose 16-bit Unsigned as the Pixel Type.
Alternatively, you may also keep the output in a TIFF format (*.tif).
Mosaic to New Raster - ArcGIS Pro
Hi,
Here are a few reasons for getting a blank raster. If one of the rasters is having null values or zero values and you have selected the null raster as "First" in mosaic raster. or Second reason is a different pixel type in a different raster i.e. one raster is 8 bit unsigned and 16 bit unsigned.
Just select the mosaic operator properly.
It was the pixel type for me.
I tried all of the suggestions in this post, ultimately finding that when I used a .GDB for my output location the tool would fail. I suggest choosing an output location that is just a folder on your system. Hope this helps.

this solution helped me too. Is there a reason why a .GDB as output location doesn't work?
