The HDL uses a laser-based 3D imaging system that scans the landscape in real-time and stitches together the terrain model from millions of laser pulses and their return. When the lander is about 1,640 feet (500 meters) from the surface, the HDL system images the surface and generates a 3D terrain map of the landing site. The NDL provides measurements that are significantly more precise than radar-based sensors in a smaller package, has less mass, and requires less power.ĭuring the final portion of the descent, the lander rotates to a vertical position to prepare a soft touchdown. NASA has previously relied on radar sensors for landing vehicles on the Moon and other planets. ![]() This feedback allows NDL to detect the lander’s velocity and altitude as it approaches the lunar surface, which increases the precision of the navigation and guidance algorithms running on the DLC. Those beams bounce off the surface and back to the instrument. The instrument transmits laser beams to the Moon’s surface. When a lander is about 4 miles (6.4 kilometers) above the surface, the NDL activates. At the same time, TRN allows a spacecraft to land near areas of scientific interest instead of landing far away and driving a rover to a targeted location. This enables the spacecraft to avoid known geographic features, such as hills and craters. By detecting and tracking the features in these live photos, the DLC knows where the spacecraft is relative to the features on the map. ![]() It compares them to preloaded maps generated from images previously captured by satellites orbiting the Moon. In the coming years, the DLC processor chip will be replaced with a more advanced processor currently in development by NASA, called the High-Performance Space Computing (HPSC) processor.Īs the spacecraft approaches the Moon, SPLICE’s TRN component uses a camera to take photos of the surface. The “brain” of the DLC is a commercial multicore processor. During the entire descent, the SPLICE DLC aboard the spacecraft autonomously operates the SPLICE sensor suite and processes algorithms for navigation, guidance, and hazard detection to enable a precise and safe landing. How would SPLICE technologies work together during a lunar landing?Īs a spacecraft begins to lower from orbit, it ignites its engine and begins a powered descent towards the surface. ![]() It also computes the hazards and determines a safe landing location.
