Laser Altimeter Based Science Studies
We have been using laser altimetry data from other missions to gain some experience with manipulation of the data. We have been looking specifically at surface roughness comparisons between the Moon (using LOLA data), Mars (using MOLA data), and Mercury (using MLA) data.
The analyse of MLA (Messenger Laser Altimeter) onboard MESSENGER spacecraft, around Mercury since March 2011, will be useful for testing the performance of BELA instrument. Indeed during the time of flight verification, the waveform of the return pulse will be implemented using the slopes map from MLA and the return pulse energy which will be send to BELA receiver will be calculating using the reflectance map.
