ICESat-2 explained

NASA’s ICESat-2, the Ice, Cloud and land Elevation Satellite-2, will provide critical observations of how ice sheets, glaciers and sea ice are changing. ATLAS (Advanced Topographic Laser Altimeter System), the single instrument on ICESat-2, will measure melting ice sheets and investigate how this effects sea level rise, investigate changes in the mass of ice sheets and glaciers, estimate and study sea ice thickness, and measure the height of vegetation in forests and other ecosystems worldwide.

why does the laserlight reflect directly onto the satellite again? Wouldnt it reflect somewhere else? No surface is perfectly orthogonal to satellite. Can someone explain?
