The Mother of all CLPS Missions
Let’s review the functioning lunar infrastructure. There’s
the Lunar Reconnaissance Orbiter (LRO) still taking pictures after a decade, India's Chandryaan-2 Orbiter, and a Chinese satellite at EM-L2 supporting the Tatu-2 rover that is crawling
on the Farside. There is also a laser reflector or two still sitting on the
lunar surface from the Apollo missions. That’s it, we’re done.
We’re returning to explore the Moon. Do we have Comms? No.
Do we have GPS? No. Navigation and Timing? No. Power? No. Landing pad? No. A
plan or architecture of the above? I’m not going to say it. But here, let me
actually quote from the International Space Exploration Coordination Group
(ISECG).
In-Situ Resource Utilization Gap
Assessment Report from 04/2021:
At the time of performing the
ISRU Gap study and writing this report, an official and internationally
accepted human lunar architecture does not exist.
But don’t despair, we have the NASA CLPS missions
(Commercial Lunar Payload Services) coming. NASA says the (CLPS) initiative
allows rapid acquisition of lunar delivery services from American companies for
payloads that advance capabilities for science, exploration, or commercial
development of the Moon. Seven missions have been awarded, each bringing about
90 kgs of payload (200 lbs) to the surface for an average cost of $75m. Oh, and they are all delayed, none have
launched yet.
If you look at the payloads, they are all scientific instruments and
other commercial payload which is all well and good but… we still don’t have
any infrastructure.
Lunar Pathfinder is a communication satellite that will communicate
with spacecraft on the lunar surface and in orbit using S-band and UHF
frequencies, then relay those communications to Earth on X-band. It is being
built by a British company (SSTL) in cooperation with the European Space Agency
(ESA). It is scheduled for launch in 2024.
It has been reported that ESA is working with NASA on an
agreement by which NASA would launch and deliver the Lunar Pathfinder into
lunar orbit on a US rocket in exchange for data-relay services for their
own missions, making NASA one of the first users of Lunar Pathfinder services.
Here is my wacky scenario which I call the Mother of all
CLPS Missions:
In May of 2022, after Starship executes a successful
orbital launch, NASA announces it will add a special CLPS mission to launch
in late 2024, focused on lunar infrastructure. The launch vehicle will be a SpaceX Starship
(which has already been designated as a CLPS eligible vehicle) and it will
launch the Lunar Pathfinder plus four yet-to launch existing CLPS missions.
Starship payload consists of:
·
Lunar Pathfinder
·
Astrobotic’s Griffin lander headed to the South
Pole, Nobile Crater region
·
Intuitive Machines Nova-M lander headed to the
South Pole, Shakelton Connecting Ridge
·
Another Intuitive Machines Nova-M lander headed
to Oceanus Procellarum
·
Masten’s Xelene lander headed to the North Pole,
Peary Crater region
In December of 2024, a SpaceX Starship launches 50 tons of
payload to TLI (trans lunar injection).
At TLI, Starship
deploys the Lunar Pathfinder satellite which attains an Elliptical Lunar Frozen
Orbit around the Moon, providing good coverage of both poles with very
minimal station-keeping. This is Phase One of a dedicated Lunar Navigation
System (LNS). Phase Two will include the Laser Communication Relay which can transmit
significantly more data and eventually replace radio frequency communications.
The first lunar lander to deploy is a scaled-up Astrobotic
Griffin lunar lander which propels itself to a powered landing at the lunar South
Pole northwest of Nobile Crater where it unloads the VIPER rover and other ice
investigating instrumentation. The lander is equipped with a GPS ranging
beacon. The GPS ranging beacons on each lander will help all subsequent
landings with precise lunar location data. The Lunar Pathfinder in orbit above,
eliminates the two week per month black-out period where rovers at the
pole could not operate because the Moon’s libration causes the pole to shift
out of line-of-site communication with Earth. This extends VIPER’s mission
capability since it will no longer have to hibernate for two weeks of each
month.
The second lander to deploy is the Intuitive Machines Nova-M which hovers near Shakelton crater. Before landing it sprays tiny microcapsules of thermite into the regolith creating a highly exothermic reaction which results in a geopolymerized subsurface landing pad. This landing pad mitigates the plume effects of the lander. Upon landing, a rover navigates to a position on the highest elevation of the Connecting Ridge and extends a solar collector to a height of 40m. (92% sunlight) This rover stores power in a high-capacity battery which can be used to recharge other bots and also powers the attached LNS ranging beacon. Regolith bots set about smoothing and microwave sintering a landing pad for a much larger rocket.
The third lander is also an Intuitive Machines Nova-M lander
which lands in Reiner Gamma in Oceanus Procellarum and deploys Lunar Vertex (to
map and analyze the natural magnetic field which forms the Reinner Gamma swirl),
Cadre rovers and other regolith collection rovers and multiple regolith
processing / oxygen production demonstration systems.
The fourth lander, Masten’s Xelene, hovers near Peary crater. It sprays alumina particles into the engine which melt and then cool within seconds on the lunar regolith, creating a landing pad. It also deploys a solar tower with LNS beacon near the Peak
of Eternal Light. (98% sunlight) It unloads the Prime-1 ice drill and three
ice-hunting rovers and other instrumentation including a hopping rover with its
own propulsion that flies over PSR craters while analyzing its contents with an
onboard spectrometer. It also deploys multiple mineral assay rover bots and
instruments.
All lunar landers and rovers are outfitted with LNS beacons
and cameras which send data to Lunar Pathfinder for relay to Earth.
There are lots of technology demonstrations that don’t have
a ride. Basically, we load up everything the landers can carry. We need to
start thinking bigger, scaling up, and taking more risk. To make great progress,
we need to start failing a little. We can learn from failure.
Note- A fully expended Starship could deliver around 60 tons
to TLI in a single launch without re-fueling. If re-fueling is in the mission, the
cost would be less and payload higher.
Fantastic idea Brian! I'm not sure NASA would be willing to take on the risk of putting all the CLPS payload eggs in one Starship basket, even assuming SpaceX qualifies their lunar lander variant for the upcoming HLS for Artemis. But this would be a brilliant way to save costs and add scientific value for U.S. taxpayers. Going Moon direct with Starship would be bold! Aren't current plans for the Artemis program calling for Starship HLS to go through the Gateway toll booth before descending to the lunar surface? But I guess those plans could stay in place and your vision is for cargo only. I think its brilliant!
ReplyDeleteThanks Unknown! Yes, Starship HLS is supposed to dock with the Gateway and recent info on Artemis says it may be more than 2 years in between crewed missions to the Moon. I described a launch to TLI but an even bolder move that could come a little later would be for Starship to re-fuel in LEO and land on the lunar surface with 100 tons of cargo. Now that would put an exclamation point on the absurdity of the SLS/Gateway architecture.
DeleteUpdate: An integral piece of this wacky scenario has come true! (I take no credit for prognostication – this has been in the works for quite some time.)
DeleteLast month (June of 2022) NASA and ESA entered into an agreement regarding the Lunar Pathfinder satellite. NASA will launch and deploy Pathfinder into lunar orbit and in exchange will receive communications services from Moon to Earth, supporting rovers and other lunar hardware. This should be in time to for the 2025 CLPS mission to Schrodinger crater near the south pole. ESA intends to have 3-4 more lunar satellites up by end of the decade. Lunar infrastructure! Keep it coming.
