NASA reveals the payloads for the first commercial Moon cargo deliveries


NASA has finalized the payloads for its first cargo deliveries scheduled to be carried by commercial lunar landers, vehicles created by companies the agency selected to take part in its Commercial Lunar Payload Services (CLPS) program. In total, there are 16 payloads, which consist of a number of different science experiments and technology experiments, that will be carried by landers built by Astrobotic and Intuitive Machines. Both of these landers are scheduled to launch next year, carrying their cargo to the Moon's surface and helping prepare the way for NASA's mission to return humans to the Moon by 2024.

Astrobotic's Peregrine is set to launch aboard a rocket provided by the United Launch Alliance (ULA), while Intuitive Machines' Nova-C lander will make its own lunar trip aboard a SpaceX Falcon 9 rocket. Both landers will carry two of the payloads on the list, including a Laser Retro-Reflector Array (LRA) that is basically a mirror-based precision location device for situating the lander itself; and a Navigation Doppler Lidar for Precise Velocity and Range Sensing (NDL) -- a laser-based sensor that can provide precision navigation during descent and touchdown. Both of these payloads are being developed by NASA to ensure safe, controlled and specifically targeted landing of spacecraft on the Moon's surface, and their use here is crucial in building robust lunar landing systems to support Artemis through the return of human astronauts to the Moon and beyond.

Besides those two payloads, everything else on either lander is unique to one vehicle or the other. Astrobotic is carrying more, but its Peregrine lander can hold more cargo -- its payload capacity tops out at around 585 lbs, whereas the Nova-C can carry a maximum of 220 lbs. The full list of what each lander will have on board is available below, as detailed by NASA.

Overall, NASA has 14 contractors that could potentially provide lunar payload delivery services through its CLPS program. That basically amounts to a list of approved vendors, who then bid on whatever contracts the agency has available for this specific need. Other companies on the CLPS list include Blue Origin, Lockheed Martin, SpaceX and more. Starting with these two landers next year, NASA hopes to fly around two missions per year each year through the CLPS program.

Astrobotic Payloads
Surface Exosphere Alterations by Landers (SEAL): SEAL will investigate the chemical response of lunar regolith to the thermal, physical and chemical disturbances generated during a landing, and evaluate contaminants injected into the regolith by the landing itself. It will give scientists insight into the how a spacecraft landing might affect the composition of samples collected nearby. It is being developed at NASA Goddard.

Photovoltaic Investigation on Lunar Surface (PILS): PILS is a technology demonstration that is based on an International Space Station test platform for validating solar cells that convert light to electricity. It will demonstrate advanced photovoltaic high-voltage use for lunar surface solar arrays useful for longer mission durations. It is being developed at Glenn Research Center in Cleveland.

Linear Energy Transfer Spectrometer (LETS): The LETS radiation sensor will collect information about the lunar radiation environment and relies on flight-proven hardware that flew in space on the Orion spacecraft's inaugural uncrewed flight in 2014. It is being developed at NASA Johnson.

Near-Infrared Volatile Spectrometer System (NIRVSS): NIRVSS will measure surface and subsurface hydration, carbon dioxide and methane - all resources that could potentially be mined from the Moon -- while also mapping surface temperature and changes at the landing site. It is being developed at Ames Research Center in Silicon Valley, California.

Mass Spectrometer Observing Lunar Operations (MSolo): MSolo will identify low-molecular weight volatiles. It can be installed to either measure the lunar exosphere or the spacecraft outgassing and contamination. Data gathered from MSolo will help determine the composition and concentration of potentially accessible resources. It is being developed at Kennedy Space Center in Florida.

PROSPECT Ion-Trap Mass Spectrometer (PITMS) for Lunar Surface Volatiles: PITMS will characterize the lunar exosphere after descent and landing and throughout the lunar day to understand the release and movement of volatiles. It was previously developed for ESA's (European Space Agency) Rosetta mission and is being modified for this mission by NASA Goddard and ESA.

Neutron Spectrometer System (NSS): NSS will search for indications of water-ice near the lunar surface by measuring how much hydrogen-bearing materials are at the landing site as well as determine the overall bulk composition of the regolith there. NSS is being developed at NASA Ames.

Neutron Measurements at the Lunar Surface (NMLS): NMLS will use a neutron spectrometer to determine the amount of neutron radiation at the Moon's surface, and also observe and detect the presence of water or other rare elements. The data will help inform scientists' understanding of the radiation environment on the Moon. It's based on an instrument that currently operates on the space station and is being developed at Marshall Space Flight Center in Huntsville, Alabama.

Fluxgate Magnetometer (MAG): MAG will characterize certain magnetic fields to improve understanding of energy and particle pathways at the lunar surface. NASA Goddard is the lead development center for the MAG payload.

Intuitive Machines Payloads
Lunar Node 1 Navigation Demonstrator (LN-1): 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.

Stereo Cameras for Lunar Plume-Surface Studies (SCALPSS): 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.

Low-frequency Radio Observations for the Near Side Lunar Surface (ROLSES): 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.
