Sure, there’s water on the moon.
However what’s it like? How a lot is there? The place is it? And, on everybody’s thoughts, may people drink it or a minimum of mine the molecules and reside off the liquid ought to we relocate to area?
These questions and extra might be answered with the assistance of the Lunar Trailblazer, a dishwasher-sized shiny satellite tv for pc that left Littleton in late January, enroute to Cape Canaveral. In Florida, the smallish satellite tv for pc will hitch a trip on a Area X Falcon 9 rocket as quickly as Wednesday and head towards a snug orbit across the moon.
“We hope it results in our understanding of the water cycle on the moon — the place water is positioned and the way it modifications over time, given the totally different temperatures, photo voltaic radiation publicity, darkish facet to gentle facet and all that,” mentioned Ryan Pfeiffer, Lockheed Martin’s program supervisor for the Lunar Trailblazer mission, on the Waterton campus in Littleton.

Expertise the most effective in Colorado information at a slower tempo, with considerate articles, distinctive adventures and a studying record that’s an ideal match for a Sunday morning.
It’s not the primary moon mission for Lockheed Martin’s area division, which is headquartered simply south of Chatfield State Park. Lockheed was a part of 1998’s Lunar Prospector to map out moon surfaces. It’s been NASA’s main contractor for the Orion spacecraft on the Artemis missions — the one sending people again to the moon. And whereas Lockheed had began on the moon rover car for the Artemis III mission, it bowed out final fall resulting from enterprise technique conflicts with a associate on the mission.
Lockheed can also be a significant a part of Colorado’s aerospace trade and it’s joined by quite a few small and huge firms who’re all-in on exploring the moon and past. Greater than 55,000 Coloradans work immediately with aerospace firms, and one other 184,000 not directly, in keeping with the state’s Workplace of Financial Growth and Worldwide Commerce.
That ranks Colorado because the nation’s prime state for per capita aerospace employment, OEDIT Govt Director Eve Lieberman mentioned in an e mail. And that continues to develop.
“We at the moment host 2,000 aerospace firms,” she mentioned, “a rise of 26% over the past 5 years, that assist and create jobs that maintain households and communities.”
An easier mission
The satellite tv for pc sat in a clear room on Lockheed’s campus in late January and seemed extra like a college science mission than high-tech area craft. (“There’s zero must put design type over perform. It’s all about perform as a result of nobody ever sees it,” Lockheed spokesperson Gary Napier mentioned.) The important thing water-searching applied sciences had been hidden behind a shiny foil-like wrapper, really aluminum honeycomb coated by carbon fiber. It’s very robust, sturdy and doesn’t develop or contract in excessive warmth or chilly.
Numerous objects had been connected to the field, sealed with what seemed like translucent orange duct tape. That’s Kapton movie, “the world’s costliest Scotch tape,” Pfeiffer joked.
Lockheed Martin prepares to ship the NASA Lunar Trailblazer spacecraft (right here exhibiting a element of the folded-up photo voltaic panels) to Kennedy Area Middle on Jan. 23. The spacecraft will gather knowledge in regards to the lunar water cycle and is scheduled to launch to the moon from Kennedy on Feb. 26. (Kathryn Scott, Particular to The Colorado Solar)
All of it, he mentioned, is “a part of the thermal blanketing. That’s how we assemble it.”
Temperatures on the moon differ broadly — from 250 levels Fahrenheit throughout the day to minus 208 at night time simply on the equator, in keeping with NASA. The thermal layers, Kapton tape and built-in thermal radiators assist the spacecraft “preserve temperatures extra like room temperature. It tries to maintain the electronics at 25 Celsius, typically colder, typically hotter,” mentioned Bronson Collins, the mission’s chief engineer. “Lots of the spacecraft’s job is managing warmth.”
The Lunar Trailblazer is a comparatively tiny mission for Lockheed and the U.S. area program. The truth is, it’s a part of a class NASA calls SIMPLEx, or Small Modern Missions for Planetary Exploration. Such missions are sometimes for analysis, are on a sub-$100 million price range, and are squeezed into underutilized area on rockets (Lunar Trailblazer is ridesharing with Intuitive Machines’ IM-2 to get a drill to the moon).
The price of the Lunar Trailblazer mission is round $80 million, which can appear excessive, however probably not compared with different NASA tasks. Artemis missions have budgets within the billions of {dollars} every, in keeping with a authorities audit. The Europa Clipper, which blasted off in October and is heading to Jupiter’s Europa moon seeking water, has a $5 billion price ticket.
Lockheed’s contribution is constructing the spacecraft. The visionary behind this water-hunting journey is Bethany Ehlmann, a professor of planetary science at California Institute of Know-how in Pasadena, California.
A educated geologist, Ehlmann specialised in learning water on Mars. However a few decade in the past, she attended a workshop about water on the moon and wound up brainstorming with colleagues from CalTech and Jet Propulsion Laboratory on a analysis mission to see what kind of water was on the moon and the place it was. NASA funded the mission in the summertime of 2019.
“The fundamental objective of the Lunar Trailblazer mission is to know the shape, the distribution and the abundance of water on the moon and the lunar water cycle,” mentioned Ehlmann, who received’t be in Florida for the launch however might be monitoring it from the operations room at CalTech. JPL and Lockheed will even assist the mission from their amenities.
She’s not anticipating to search out liquid that may be splashed round — extra like ice, or frost, or water molecules embedded in rocks. Since there’s no environment on the moon, water doesn’t pool or settle into lakes as on Earth. On the moon, water would immediately vaporize. But it surely seems to be within the crevices of the moon the place the solar by no means shines. The satellite tv for pc that Lockheed constructed can higher look at what types of water exist on the moon.
“We’re making maps of the place the water is and the way a lot is there as a result of if we’re going to ship (manned) missions … you must know the place to go and the way a lot you’re more likely to discover,” she mentioned. “Are you more likely to discover minerals with half a % of water inside them? Or are you going to actually discover a block of soiled ice sitting on the floor? It’s type of necessary to reply that query to information future landed explorations of the moon.”
Easy methods to discover water on the moon
To maintain the prices throughout the smaller price range, Lunar Trailblazer isn’t ranging from scratch. It’s utilizing expertise from its science pals.
JPL supplied a particular imaging spectrometer known as the Excessive-resolution Volatiles and Minerals Moon Mapper or HVM3 to seize photos not seen to the human eye (“When it takes an image of the floor, each single pixel has a spectrum related to it and from the spectrum, you possibly can inform what the floor is made from,” Ehlmann mentioned).
The Lunar Thermal Mapper from the College of Oxford can measure temperatures on the moon floor. The instrument was funded by the UK area company as a world partnership. It creates warmth maps primarily based on temperature, and also will map out bodily properties of the moon in larger element.
Ehlmann mentioned they’re additionally counting on present moon knowledge from previous missions that “present hints of the place water is, like on a couple of kilometers scale,” she mentioned. The Lunar Trailblazer can zoom in on these actual spots and take larger decision photos alongside the strains of “tens of meters scale,” or magnifying objects by greater than 100 occasions.
“We’re capable of actually leverage the truth that NASA and different international locations have already made fairly good maps of the moon,” she mentioned. “However we’re going to make an superior water-focused one at a decision that can allow future landers or rovers or hoppers or astronauts to go precisely to essentially the most fascinating water deposits.”
When it does launch, the satellite tv for pc will shoot previous the moon, spend a couple of months working its method again and settle about 100 kilometers away from the moon’s floor. That journey may take 4 to seven months. As soon as in orbit, it is going to begin scanning to collect particulars of the suspected water spots down beneath. The instruments will measure mirrored gentle and thermal emissions so scientists can analyze the composition and temperature to see if what they assume is water is water and in that case, discover out if it modifications all through the day.
From launch to the top, Lunar Trailblazer’s journey is anticipated to final two years.
On the peak of the mission, there have been in all probability simply 4 to 5 technicians assembling the car, whereas engineers had been again of their workplaces. By the point the satellite tv for pc shipped out of Littleton final month, Lockheed didn’t have anybody engaged on the mission full time. They’d moved on to work on different Lockheed area tasks, together with Artemis missions, lunar infrastructure and planetary robotic and climate missions, reminiscent of DAVINCHI and GeoXO.
“It’s actually unlocking a type of future habitation of the moon long run, which is absolutely onerous to do with out water. And should you don’t know the place it’s going to be, it’s actually onerous to plan your mission,” Pfeiffer mentioned. “That’s a part of the science that the staff actually needs to get out of this.”
In Colorado, it’s not nearly water
The hunt for water in area is worldwide, with missions in progress from India, China, Russia, Korea and Japan, mentioned Angel Abbud-Madrid, a professor and director of the Middle for Area Assets on the Colorado Faculty of Mines.
“As an excellent Coloradan, you understand that water is an important useful resource that people go after in every single place they go,” Abbud-Madrid mentioned. “Not solely is it necessary for people to outlive, however should you’re on the moon, water can be helpful to develop crops and it’s the most effective shielding factor from radiation there’s.”
It is also used as gas, he added. Warmth it up and it turns into steam to propel a rocket. Break up it into hydrogen and oxygen to create “essentially the most energetic propellant mixture that you’ll find,” he mentioned. “And after getting gas in area, you possibly can keep away from bringing every thing from Earth, which is extraordinarily costly as a result of we’ve got to beat this factor known as gravity.”
The dream is to get individuals to the moon once more, and never only for a flyby, however to reside for prolonged intervals of time. To do this means getting rockets, lunar landers, rovers, tools to extract water and constructing infrastructure up there.
All of that has a Colorado connection, Abbud-Madrid mentioned.
Lockheed has the Orion spacecraft to take us to the moon. United Launch Alliance, headquartered in Centennial has the Vulcan rocket, which is offering extra entry to area. Blue Origin, which opened an workplace in Highlands Ranch in 2022, simply launched the New Glenn rocket, which might compete with SpaceX to create space extra inexpensive.
“Reducing the price is essential,” Abbud-Madrid mentioned. “The second you decrease (the price of) entry to area, issues are going to start out occurring. Similar to on Earth. It has been so costly that just a few international locations have gone and solely about 600 individuals have gone out to area.”
As soon as in area, Japan’s iSpace, which picked Denver as its U.S. headquarters in 2020, is designing a lunar lander scheduled to take off subsequent 12 months for the far facet of the moon.
Golden-based Lunar Outpost is working with Common Motors and Goodyear Tire & Rubber Firm on the Lunar Daybreak car, which is able to assist the astronauts drive across the moon to discover farther into its excessive setting.
Lunar Outpost has additionally partnered with Nokia to get the first 4G/LTE mobile community on the moon, which is becoming a member of the Trailblazer on the Falcon 9 rocket. Honeybee Robotics, a subsidiary of Blue Origin with an workplace in Longmont, has developed drills that might be used on the moon’s south pole to search out out if there’s water beneath the floor.
And as soon as there’s gas obtainable, it is going to make extra sense for area craft to gas up on the moon since there’s much less gravity. The vitality for rockets to push previous Earth’s gravity and get into area may be 90% of the rocket’s mass. So … area gasoline stations. Lafayette-based Orbit Fab, which in 2019 turned the primary non-public firm to resupply water to the Worldwide Area Station, is engaged on refueling stations for spacecraft.
“A base on the moon is within the plans by NASA by the top of the last decade,” Abbud-Madrid mentioned. “When you begin having people for a sustained presence, you’re going to have to offer them with water to drink, oxygen to breathe, building supplies for habitats and touchdown paths and roads. … All these firms are engaged on that.”
And from there, there’s the remainder of deep area, mentioned Whitley Poyser, director of Lockheed Martin Area’s enterprise transformation program workplace.
“For me personally, I like to speak about deep area as all of the planets aside from Earth. And that’s not as a result of we don’t care about Earth however as a result of it helps us higher perceive the place we reside,” Poyser mentioned. “Going to the moon is a vital a part of that ecosystem. We now have to know our closest planetary physique to assist us be told, particularly as we discover deeper into deep area, which can also be our mission.”
