Animation of Sol 3 Lidar Use
This series of images was taken by the Surface Stereo Camera on NASA's Phoenix Mars Lander during the firing of the spacecraft's lidar on Sol 3. The camera used its green filter (532 nanometers), which includes the wavelength of the lidar beam. The 9 images show the beam on and off. The low contrast of the beam confirms the effectiveness of the lidar dust cover, because the laser continues upward rather than scattering much light into the cameraI.
