Laser Retro-Reflector Array (LRA)
LRA is a collection of eight approximately half inch (1.25 centimeter) retro-reflectors – a unique kind of mirror that is used for measuring distance -- mounted to the lander. This mirror reflects laser light from other orbiting and landing spacecraft to precisely determine the lander’s position. It is being provided by NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
LN-1 is a CubeSat-sized experiment that will demonstrate autonomous navigation to support future surface and orbital operations. It has flown on the space station and is being developed at NASA Marshall.
SCALPSS will capture video and still image data of the lander’s plume as the plume starts to impact the lunar surface until after engine shut off, which is critical for future lunar and Mars vehicle designs. It is being developed at NASA Langley, and also leverages camera technology used on the Mars 2020 rover.
ROLSES will use a low-frequency radio receiver system to determine photoelectron sheath density and scale height. These measurements will aide future exploration missions by demonstrating if there will be an effect on the antenna response or larger lunar radio observatories with antennas on the lunar surface. In addition, the ROLSES measurements will confirm how well a lunar surface-based radio observatory could observe and image solar radio bursts. It is being developed at NASA Goddard.
