two US missions are set to launch a new era of commercial lunar exploration

Two commercial spacecraft are scheduled to launch to the Moon in early 2024 as part of a NASA initiative called the Commercial Lunar Payload Service CLPS. This program goals to launch a commercial transportation service that may deliver NASA experiments and other cargo to the lunar surface.

If successful, these missions can be the primary lunar landings by a spacecraft designed and operated by private corporations. They could potentially open a new era of commercial lunar exploration and science.

CLPS was launched by NASA in 2018. An initial group of nine corporations received an invite to join this system. They included Astrobotic AND Intuitive Machines, the two corporations behind these missions. Both missions are scheduled to land inside a week of launch.

NASA’s first launch and first flight in 2024 can be the Peregrine lunar lander, built by Pittsburgh-based Astrobotic. Its launch is scheduled for January 8 on the earliest. Basically, the lander is a box in regards to the size of a mean garden shed, containing several separate experiments.

These include a set of mirrors called a laser reflector array, used to accurately position the lander from orbit. There are also many spectrometers – instruments that separate and measure the various colours present in light. They will measure radiation on the lunar surface and search for traces of water in lunar soil.

One of them, Neutron spectrometer system, will search for materials containing hydrogen on the surface, which can indicate the presence of water under the bottom surface. This water may someday be utilized by human explorers.

There are two fundamental sources of dangerous radiation to humans in space. One of these is the Sun, which releases electrons, protons and heavier ions that are accelerated to a significant fraction of the speed of light.

These energetic particle (SEP) events are more likely to occur during peak solar activity (maximum solar activity), which occurs every 11 years. However, this doesn’t mean respite during solar minimum.

The second source of harmful radiation is galactic cosmic rays (GCR). These energetic particles are created outside the solar system, possibly by explosive phenomena comparable to exploding stars (supernovae).

During periods of lower solar activity (including solar minimum), the Sun’s magnetic field, which extends over the complete Solar System, weakens. It makes this possible more GCR reach out to us as a substitute.

Another spectrometer on Peregrine will measure each SEP and GCR on the Moon. This is vital for investigating how dangerous the radiation environment on the lunar surface can be for future human explorers.

Polar landing

The second spacecraft to be launched in early 2024 is: Nova-C lander. It was designed by Houston-based Intuitive Machines and has a similar volume to Peregrine, but in the form of a tall, hexagonal cylinder. It can be equipped with several instruments, including its own set of laser reflectors. Nova-C is currently scheduled for launch in mid-February.

Other instruments include a set of cameras to create a 3D image of the Nova-C landing site. This will enable scientists to estimate how much material can be blown away by the landing rocket’s exhaust plume during descent. Potentially any blown material may very well be photographed to get an idea of ​​the composition of the surface material.

“Radio observations of the photoelectron shell of the lunar surface” (Rolses) is designed to measure the effect of the extremely thin lunar atmosphere and mud environment on the lunar surface on radio waves.

The behavior of electrically charged dust particles on the Moon is a technical challenge that future explorers may have to grapple with, because abrasive particles can attach to surfaces and mechanical devices and potentially cause damage if inhaled by astronauts.

The private experiment aboard Nova-C is the International Lunar Observatory MOP-X, which can aim to capture some of the primary images of the Milky Way galaxy from the lunar surface. This would exhibit the concept of lunar astronomy.

Landing places

Peregrine’s landing site is a bay on the western side of Mare Imbrium, referred to as Sinus Viscositatis (Viscous Bay). Here there are two volcanic mountains, the so-called Gruithuisen domes they are made of a different material than the plains surrounding them.

The plains are a form of basalt, while the domes are composed of silica. Both are volcanic in origin, but one probably formed from lava the viscosity of mango chutney (silica) and the opposite from more fluid lava (basalt).

On Earth, siliceous lavas typically require the presence of each water and plate tectonics. However, it is just not known whether the Moon has plate tectonics or water within the quantities mandatory for siliceous lava. The Gruithuisen domes subsequently represent a geological puzzle that Peregrine could go a way to solving.

Nova-C’s landing site is the Malapert A crater – which is especially interesting for lunar exploration since it lies close to the Moon’s south pole. The surrounding mountains permanently shield this depression from sunlight, leaving it in constant darkness.

As such, it’s one of the coldest places within the solar system, and within the absence of sunlight, it’s a place where water ice supplied by comets which were pounding the surface over eons can remain stable. Future explorers could use it to support life and produce rocket fuel.

Both spacecraft carry additional payloads from private investors. Peregrine includes a “DHL Spacebox” that may carry personal belongings of paying customers, while Nova-C includes “The Humanity Hall of Fame” – a list of names to be sent to the moon for posterity. Such payloads can generate additional funds for startup corporations.

Several other corporations are expected to launch their first payloads to the Moon in the following few years. With more contributions from private corporations – assuming the primary few missions are successful – we could soon see a new era in lunar exploration.
