Next Generation Lunar Retroreflector (NGLR)

A Next Generation Lunar Retroreflector (NGLR) sits on an adjustable multidirectional mount.
Dr. Douglas Currie
  • Summary: The Next Generation Lunar Retroreflector (NGLR) serves as a target for lasers on Earth to precisely measure the distance between Earth and the Moon. The NGLR will reflect very short laser pulses from Earth-based Lunar Laser Ranging Observatories (LLROs). The laser pulse transit time to the Moon and back is used to determine the distance. The original Apollo retroflectors provided the coordinates for the Moon that we use today. NGLR will greatly improve upon the Apollo results with sub-millimeter range measurements, providing advances in the lunar coordinate system in advance of the Artemis program. The NGLR will support the Lunar Laser Ranging Program for a long-term investigation of lunar physics, Astrophysics and Cosmology. The improved ranging accuracy from NGLR will contribute to bettering our understanding of the inner structure of the Moon and in addressing theories of dark matter.

Radiation Tolerant Computer System (RadPC)

Radiation Tolerant Computer System (RadPC) CLPS payload
RadPC will provide detailed radiation information about the lunar landing site with a focus on ionizing radiation.
NASA/Montana State University
  • Summary: The Radiation Tolerant Computer (RadPC) is a technology demonstration of a radiation tolerant computer system. RadPC implements a set of fault mitigation strategies to recover from single event effects (SEEs) caused by ionizing radiation. The recovery procedures are implemented on a commercial Field Programmable Gate Array (FPGA). By using a modern commercial FPGA, an acceptable level of total ionizing dose (TID) can be achieved inherently while simultaneously taking advantage of the performance and power efficiency of commercial parts. The RadPC payload contains the computer technology running a comprehensive test program along with instrumentation on its state-of-health. Three dosimeters (detectors designed to measure the ionizing radiation) tuned to different sensitivity levels are included in the payload to provide further environmental information for correlation to RadPC’s performance and to provide detailed radiation information about the lunar landing site.
  • Type of Instrument: Radiation tolerant computer system: payload enclosure, dosimeter, thermal management system, Field Programmable Gate array circuit
  • Key Measurement: Ionizing radiation energy levels
  • Task Order: CLPS TO 19D

  • Summary: RAC will determine how lunar regolith sticks to a range of materials exposed to the Moon’s environment throughout the lunar day. Its purpose is to help scientists progress in their endeavor to protect spacecraft, spacesuits and habitats from abrasion. Thirty samples, including a dust collection disk, thermal control paint, Kapton, and titanium, have been provided by NASA and the industry. The samples constitute two identical sets of 15 samples that are contained in two wheels, denoted “A” and “B,” which rotate into view of cameras every 24 hours for imaging. The “B” wheel, which is covered until post-landing commissioning is complete (a few hours after landing), acts as a control for transit effects on the “A” wheel, which is exposed for the entire mission. RAC will also quantify accumulation rates caused by landing and routine lander operations. RAC will collect IR, UV, and temperature data to augment science return of the 5.1 MP images. Operations are autonomous with some ground commanding access for recovery and contingency. Components of this experiment are derived from Materials International Space Station Experiment (MISSE) on ISS.
  • Type of Instrument: Dust collector/detector - Collection of panels with different materials
  • Key Measurement: RAC will measure accumulation rates of lunar regolith on the surfaces of several materials (e.g., solar cells, optical systems, coatings, and sensors) through imaging to determine their ability to repel or shed lunar regolith/dust.

Lunar Magnetotelluric Sounder (LMS)

Lunar Magnetotelluric Sounder (LMS) CLPS payload
LMS will determine the structure and composition of the Moon’s mantle by studying electric and magnetic fields.
NASA/Southwest Research Institute
  • Summary: The Lunar Magnetotelluric Sounder measures natural time-varying electric and magnetic fields from the solar wind and Earth’s magnetosphere to determine the electrical conductivity profile of the Moon’s interior. This investigation will constrain the temperature structure and history of the Moon, as well as distinguish the "normal" Mare Crisium region from the anomalous western nearside of the Moon (where all of the Apollo landings occurred). The instrument uses components and heritage from several prior missions, including MAVEN, THEMIS, and MSL-RAD.
  • Type of Instrument: Electrometer and Magnetometer
  • Key Measurement: The ratio of the electric field spectrum to the magnetic field spectrum at the lunar surface determines the frequency-dependent ground impedance, akin to Ohm's Law. This in turn allows the depth-dependent conductivity to be recovered.
  • Task Order: CLPS TO19D

NASA/GSFC/Honeybee Robotics
  • Summary: PlanetVac will collect samples of lunar regolith (soil) from the surface using a pneumatic technique (powered by compressed gas) and its delivery system will transfer the samples to other instruments that will analyze the material. The payload will be attached to a lander footpad and connected to instruments via a pneumatic transfer hose. Lunar PlanetVac is a pneumatic based sample acquisition and delivery system that will acquire and transfer lunar regolith from the surface to other instruments that will analyze the material. It consists of three subsystems: Sampling Head, Transfer Tube, and Sample Container. Pressurized gas is jetted towards the surface within the Sampling Head, stirring up the regolith into a cloud of dust. A secondary set of jets pointed up the Transfer Tube carry this regolith directly into a Sample Container. The sampling operation takes a few seconds and does not require human in the loop. Captured regolith, up to 1 cm in size, will be sieved and photographed inside the Sample Container. LPV is classified as a technology is applicable for any mission or instrument that requires a surface (or subsurface) sample.
  • Type of Instrument: Pneumatic regolith sampling system
  • Key Measurement: LPV will collect and sort surface lunar regolith within a sample collection chamber.
  • Task Order: CLPS TO 19D

Lunar Instrumentation for Subsurface Thermal Exploration with Rapidity (LISTER )

LISTER will penetrate the Moon’s core, track the flow of heat, and quantify it.
NASA/GSFC/Texas Tech
  • Summary: LISTER will measure the flow of heat originating from the interior of the Moon. It is designed to penetrate 2- to 3-m depth into the Moon’s rock and dust surface (the lunar regolith) and determine the heat flow as a product of two separate measurements: thermal gradient – how temperature changes with depth; and thermal conductivity – how well heat flows via conduction – at various depths using five measurements.
  • Type of Instrument: pneumatically-drilled subsurface thermal probe
  • Key Measurement: quantify the heat flow through temperature and the thermal conductivity measurements
  • Task Order: CLPS TO 19D
  • Lead Development Organization: Texas Tech University
  • Payload PI: Dr. Seiichi Nagihara

Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS) 1.1

A set of four cameras mounted on a metal wheel, along with control circuitry and processing units, undergo vibration testing in a lab. For some reason, there is a tape dispenser that appears to be from the 70s in the background. I imagine this wasn't part of the experiment.
SCALPSS undergoing environmental testing in the lab.
NASA/LaRC
  • Summary: SCALPSS 1.1 is a slightly enhanced version of the original SCALPSS payload, which deployed as a part of CLPS Task Order 2-IM (Intuitive Machines’ IM-1 mission). It will capture video and still image data of the lunar surface prior to, during, and after the lander’s descent engine plumes interact with the lunar surface. The 1.1 version features two additional cameras, which are optimized to begin capturing image data at a higher altitude prior to the expected onset of plume-surface interaction. By collecting topographical data through stereo photogrammetry both prior to and after Plume-Surface Interactions (PSI), an accurate measurement of the total erosion and crater volume can be made. The enhancements on 1.1 will provide a more accurate before-and-after PSI comparison. Transient data collected while PSI is occurring will add information regarding the rate at which the surface morphology changes. This data will then be used to validate computational models of PSI effects which are critical in the design and risk evaluation of future large lunar landers. The SCALPSS 1.1 payload is based off the Entry, Descent, and Landing Camera Suite (EDL) used by the Mars 2020 lander, which acquired visual data via complement of camera systems.
  • Type of Instrument: Camera
  • Key Measurement: Topography data to accurately determine the total erosion and crater volume during PSI as well as the rate of change. Return of validation data for computational models of PSI effects to be used on future landers.
  • Task Order: CLPS TO19D

The Electronic Dust Shield (EDS) will test the use of electricity to protect sensors from lunar atmospheric materials.
NASA
  • Summary: Hazardous dust is present on Mars, the Moon, and comets. The Electrodynamic Dust Shield (EDS) is an active dust mitigation technology that uses electric fields to move dust from surfaces and to prevent dust accumulation on surfaces. The EDS, which can lift, transport, and remove particles from surfaces with no moving parts, will be demonstrated for the first time on the lunar surface. This technology will show the feasibility of self-cleaning glass and thermal radiator surfaces. In addition to dust removal, the EDS will apply lunar dust to these surfaces using a new reduster technology that will lift and transport dust from the lunar surface to the desired location without moving parts or gasses. The EDS will be released from a fifth leg of the lander and positioned directly onto the lunar surface to maximize dust contact. High resolution images will determine the dust removal efficiency of the EDS on the lunar surface.
  • Type of Instrument: Dust Shield
  • Key Measurement: Demonstrate the operation of two Electrodynamic Dust Shield (EDS) systems on the lunar surface: EDS for a small camera to be located under the lander’s deck and EDS on a white aluminum panel to be located on a lander’s footpad.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
