Completed experiments on International Space Station to help answer how boiling and condensation work in space

After a decade of preparation and two years of active experiments in space, a facility that Purdue University and NASA's Glenn Research Center in Cleveland designed, built and tested has completed its test campaign on the International Space Station.

The Flow Boiling and Condensation Experiment (FBCE), led by Purdue professor Issam Mudawar, gathered vital data for engineering innovations to help astronauts travel farther into space and conduct long-duration missions on the moon or Mars. The data will also support the design of future spacecraft propulsion, thermal management systems, in-space refueling and vapor compression heat pumps for planetary bases.

"We were asked to create an experiment to test flow boiling in microgravity, and I'm thrilled to see that we've delivered in a big way," said Mudawar, the Betty Ruth and Milton B. Hollander Family Professor of Mechanical Engineering and FBCE's principal investigator. "The amount of data coming out of the FBCE is just absolutely enormous, and that's exactly what we want."

Mudawar's space-based experiment tackles a simple question: How do we keep future vehicles and facilities cool in space's harsh environment? For example, the moon's surface fluctuates wildly between minus 410 degrees and 250 degrees Fahrenheit; to create a human habitat there, reliable thermal management will be essential.

Traveling farther into space requires cryogenic fuel depots, but the flow physics of cryogenic liquids in microgravity haven't been fully understood. Even future propulsion systems, such as nuclear fission or Rankine cycle heat engines, will also require efficient cooling systems capable of operating in a zero-gravity environment.

For all these reasons, NASA solicited research proposals on the topic and selected a proposal submitted by Mudawar, who is one of the most cited researchers on flow boiling and condensation, and Glenn's Mojib Hasan.

In flow boiling, heat is removed by flowing a liquid that then boils, phase-changing into a gas, and then later condensing back into a liquid. While this efficient thermal management solution has been studied in-depth on Earth, no one knew if it was feasible in space.

"We have developed over a hundred years' worth of understanding of how heating and cooling systems work in Earth's gravity," Mudawar said, "but we haven't known how they work in weightlessness."

Enter the FBCE, which started operating on the space station in 2022. About the size of a refrigerator, FBCE contains two Purdue-designed test modules—one for flow boiling and one for condensation—integrated with a fluid system that Purdue researchers and NASA Glenn designed together. NASA Glenn built the fluid system along with avionics modules. Sitting in the space station's Fluids Integrated Rack, the fluid system enables researchers to conduct space station experiments autonomously from the ground.

"The FBCE experiments are crucial in two ways," Mudawar said. "Not only do they generate fundamental data that would be difficult for us to gather on Earth, but they also serve to validate theoretical models that we have spent years developing. Once the models are validated, it becomes possible for NASA to more accurately predict the fluid physics of lower-gravity environments, such as the moon or Mars."

Boiler up

Mudawar started this project in 2011 when NASA selected his proposal after a decadal survey from the National Academies emphasized the need for this research.

"Every 10 years, the National Academies conduct a survey that advises NASA what specific aspects they should focus on," Mudawar said. "This report indicated a lack of fundamental models of how fluids behave in microgravity. That's when I began work with NASA Glenn to create an experimental facility to study fluid flow and phase change in space."

The first prototype FBCE flew on parabolic airplane flights with Zero Gravity Corp. (ZERO-G). Purdue students and NASA Glenn-qualified operators conducted experiments on that flight during 15-second periods of microgravity. After promising results and years of hardware development, testing and flight qualification, the final version of the facility came together at NASA Glenn.

After passing NASA's design, safety and readiness reviews, FBCE's flow boiling module was launched to the space station in August 2021 and began operations in early 2022. Last August, the condensation module of FBCE launched, replacing the flow boiling module. Purdue completed its test campaign in July.

The mountains of data gathered from FBCE's experiments will form the basis of fundamental models and future research for years to come.

"This is among NASA's largest and most complex experiments for fluid physics research," Mudawar said. "We have published more than 70 papers on reduced gravity and fluid flow since the project's inception and even contributed to the most recent National Academies decadal survey based on our findings. Collectively, these papers are really almost like a textbook for how boiling and condensation works in space."

Cool future

While the Purdue test campaign has ended, FBCE isn't going anywhere. The facility will remain on the space station for other researchers who want to experiment with fluid physics in space.

"My original proposal established that FBCE would eventually become a national resource," Mudawar said. "Other investigators have already started using it since our campaign ended. It's my hope that the data coming from FBCE will help establish the science of cooling spacecraft for years to come."

All the major structures that will form the core stage for NASA’s SLS (Space Launch System) rocket for the agency’s Artemis III mission are structurally complete. Technicians finished welding the 51-foot liquid oxygen tank structure, left, inside the Vertical Assembly Building at NASA’s Michoud Assembly Facility in New Orleans Jan. 8. The liquid hydrogen tank, right, completed internal cleaning Nov. 14. NASA/Michael DeMocker As NASA works to develop all the systems needed to return astronauts to the Moon under its Artemis campaign for the benefit of all, the SLS (Space Launch System) rocket will be responsible for launching astronauts on their journey. With the liquid oxygen tank now fully welded, all of the major structures that will form the core stage for the SLS rocket for the agency’s Artemis III mission are ready for additional outfitting. The hardware will be a part of the rocket used for the first of the Artemis missions planning to land astronauts on the Moon’s surface near the lunar South Pole. Technicians finished welding the 51-foot liquid oxygen tank structure inside the Vertical Assembly Building at NASA’s Michoud Assembly Facility in New Orleans Jan. 8. The mega rocket’s other giant propellant tank – the liquid hydrogen tank – is already one fully welded structure. NASA and Boeing, the SLS core stage lead contractor, are currently priming the tank  in another cell within the Vertical Assembly Building area called the Building 131 cryogenic tank thermal protection system and primer application complex. It completed internal cleaning Nov. 14. Manufacturing hardware is a multi-step process that includes welding, washing, and, later, outfitting hardware.The internal cleaning process is similar to a shower to ensure contaminants do not find their way into the stage’s complex propulsion and engine systems prior to priming. Once internal cleaning is complete, primer is applied to the external portions of the tank’s barrel section and domes by an automated robotic tool. Following primer, technicians apply a foam-based thermal protection system to shield it from the extreme temperatures it will face during launch and flight while also regulating the super-chilled propellant within. “NASA and its partners are processing major hardware elements at Michoud for several SLS rockets in parallel to support the agency’s Artemis campaign,” said Chad Bryant, acting manager of the Stages Office for NASA’s SLS Program. “With the Artemis II core stage nearing completion, the major structural elements of the SLS core stage for Artemis III will advance through production on the factory floor.” The two massive propellant tanks for the rocket collectively hold more than 733,000 gallons of super-chilled propellant. The propellant powers the four RS-25 engines and must stay extremely cold to remain liquid. The core stage, along with the RS-25 engines, will produce two million pounds of thrust to help launch NASA’s Orion spacecraft, astronauts, and supplies beyond Earth’s orbit and to the lunar surface for Artemis III. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch. Through Artemis, NASA will send astronauts—including the first woman, first person of color, and first international partner astronaut—to explore the Moon for scientific discovery, economic benefits, and to build the foundation for crewed mission to Mars. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, exploration ground systems, advanced spacesuits and rovers, Gateway, and human landing systems.

Cryofuels Come Under Pressure - Technology Org

A carbon composite tank developed for NASA enables the move from fossil fuels to cryofuels.

Replacing jet fuel with hydrogen would be good for business and the environment. Hydrogen generates no carbon emissions and packs three times the energy per pound of hydrocarbon fuel, but there are some problems.

One of the biggest is that current airplane fuel tanks can’t safely hold hydrogen. A solution is the carbon-fiber Blended Hybrid Laminate (BHL) cryotank developed by Gloyer-Taylor Laboratories (GTL) Inc. of Tullahoma, Tennessee.

Landing on a lunar surface is risky, and making the craft as light as possible is only one of many requirements. The mid-sized lander concept in this illustration, which would deliver a rover to the polar regions of the Moon, could benefit from a lightweight carbon composite cryofuel tank developed by Gloyer-Taylor Laboratories.

While NASA is testing it to carry cryofuels – particularly liquid oxygen – into space, a commercial airline is interested in the fact that the BHL can hold ultra-cold fuels without developing the microcracks that shorten the lifespan of other carbon composite tanks.

Hydrogen has one of the lowest boiling points of any element, meaning its liquid form must be kept extremely cold, or it needs to be kept under remarkably high pressure.

That requires a strong tank, usually made of steel or aluminum. Paul Gloyer, president of GTL, said breakthroughs in the use of carbon fiber and resin to wrap tanks have made them lighter than equivalent metal tanks. He wanted them to be even lighter.

A proprietary combination of materials and a manufacturing process developed by the company has produced a new type of carbon composite tank for cryofuel storage with walls thinner than a business card. Gloyer describes the BHL cryotank as a “stiff balloon.”

This unique carbon composite tank for cryofuels developed by Gloyer-Taylor Laboratories with NASA support is lightweight, making it ideal for aviation. And it’s designed to hold cryogenic fuels under extreme pressure, so it can be used to hold hydrogen and replace fossil fuels, eliminating greenhouse gas emissions.

It can withstand repeated cycles of pressurization and thermal changes that occur as the cryofuel tank is filled and emptied without developing the microcracks that result in dangerous leaks in other carbon tanks. The flexible nature of the material and thin construction mean the tank can hold more fuel per pound of tank mass.

A measurement of the force that leads tanks to crack is called microstrain. Conventional carbon-fiber cryotanks without liners tend to leak at about 3,000-5,000 microstrain. Testing has shown that the BHL tank can withstand more than 20,000 microstrain at cryogenic temperatures, said Gloyer.

Partly funded by multiple Small Business Innovation Research contracts from several NASA field centers including Marshall Space Flight Center in Huntsville, Alabama, the BHL is undergoing assessment for commercial space applications at the center.

The BHL technology has the potential to reduce cryofuel tank mass by 30% to 50% for small spacecraft propulsion systems, according to John Peugeot, a propulsion engineer at Marshall.

One space company is evaluating the new lightweight, high-capacity tank for its commercial lunar lander, according to Gloyer. A significant benefit of using the smaller, lighter tank will be the craft’s capacity to carry more technology and science payloads.

Meanwhile, several aircraft developers are combining the tank with hydrogen fuel cells and an electric engine to provide cleaner, cheaper long-distance air travel. Current cryotanks that fit on a plane are so heavy they can only carry 5% to 6% hydrogen by mass, supporting only short flights, according to GTL. The BHL cryotank, including insulation, can hold 60% to 70% hydrogen by mass.

This extra hydrogen would let a plane fly four times as far as a conventional jet fuel-powered aircraft, cutting operating costs in half and creating a strong economic incentive to switch to hydrogen fuel. Gloyer said the alignment of economic and environmental benefits could result in the rapid adoption of hydrogen fuel, reducing carbon emissions and enhancing prosperity.

Promising early tests for variable-thrust landing engine

As part of ESA's Future Launchers Preparatory Program (FLPP), the first phase of hot-fire tests has been completed on a new, variable-thrust rocket engine in Warsaw, Poland. The engine is being developed by a Polish consortium investigating new designs for propellant valves and injectors that can vary the thrust of rocket engines powered by more sustainable and storable propellants. Such engines have great potential for use in future space missions and reusable rockets.

The new engine is called the Throttleable Liquid Propulsion Demonstrator (TLPD), it is now being dismounted and inspected, with the results being analyzed at the site of prime contractor Łukasiewicz Research Network—Institute of Aviation (Lukasiewicz-ILOT) in Poland, with partners Astronika and Jakusz SpaceTech, before the next phase of testing begins.

Liquid propellants that last

The throttleable engine includes a newly designed fuel injector and control valves. With a thrust of 5kN (compared to the Ariane 6 upper stage engine's thrust of 180 kN), the TLPD engine is perfect for the upper stage of smaller rockets, for in-space vehicles, for launcher kick-stages and exploration missions. The ability to modify its thrust makes it also very interesting for landing spacecraft on Earth, the moon and beyond.

The new rocket engine is powered by storable propellants hydrogen peroxide and ethanol, which are safer and less toxic than others currently in use (such as hydrazine and nitrogen tetroxide). Compared to cryogenic propellants, like liquid oxygen and hydrogen, storable propellants require no active cooling measures and will not diminish between subsequent engine firings.

Rocket engines powered by storable propellants can have long lifetimes in space and are easy to reliably and repeatedly ignite during missions that last many months. Cryogenic propellants also require energy to begin combustion, provided by an "igniter," whereas the TLPD propellants ignite upon contact with each other, making the engine simpler and more reliable. % buffered

At heart: New electronically controlled valves and fuel injector

The main goal of the current throttleable engine project is to test a newly developed system of valves and a movable "pintle" injector—a type of propellant injector used in "bipropellant" rocket engines—all commanded by an electronic control system.

The valves ensure the appropriate rate of propellant flows into the combustion chamber—the higher the rate, the greater the thrust. The fuel injector mixes the two propellants (the ethanol fuel and hydrogen peroxide oxidizer) while they are injected at high pressure into the chamber, maintaining stable combustion as their rate varies coming through the valves. All of this ensures an efficient and controlled combustion process can take place.

Next: Going full throttle

The TLPD engine has been designed to be throttled down to 20% and up to 110% of its optimal level of thrust. Such "deep" throttling, i.e., the ability to really vary the engine's power, is necessary for landing rocket stages on Earth, or spacecraft on the moon or other planetary bodies.

The hot fire tests just completed in Phase A were originally planned to be purely static, testing the engine's ability to fire at a constant rate. The engine was fired 17 times for up to 10 seconds, while the amount of fuel and oxidizer flowing in was kept constant.

The initial results were so promising that teams decided to move onto the next phase earlier than planned—dynamic throttling. The engine was fired up twice again, each time for 15 seconds, during which the thrust was varied down to 20% and up to 80% of its optimal level.

Once the results have been analyzed, the TLPD engine will be remounted and the full scope of planned dynamic tests will begin, with even longer firing durations. This set of tests is expected to start in October and will really put the "throttleability" of the engine to the test.

ESA's Future Launchers Preparatory Program and Lukasiewicz-ILOT are now in discussions about continuing the project, building on these test results and working towards the design of an overall throttleable flight engine.

The Big Build: Artemis I Stacks Up

Our Space Launch System (SLS) rocket is coming together at the agency’s Kennedy Space Center in Florida this summer. Our mighty SLS rocket is set to power the Artemis I mission to send our Orion spacecraft around the Moon. But, before it heads to the Moon, NASA puts it together right here on Earth.

Read on for more on how our Moon rocket for Artemis I will come together this summer:

Get the Base

How do crews assemble a rocket and spacecraft as tall as a skyscraper? The process all starts inside the iconic Vehicle Assembly Building at Kennedy with the mobile launcher. Recognized as a Florida Space Coast landmark, the Vehicle Assembly Building, or VAB, houses special cranes, lifts, and equipment to move and connect the spaceflight hardware together. Orion and all five of the major parts of the Artemis I rocket are already at Kennedy in preparation for launch. Inside the VAB, teams carefully stack and connect the elements to the mobile launcher, which serves as a platform for assembly and, later, for fueling and launching the rocket.

Start with the boosters

Because they carry the entire weight of the rocket and spacecraft, the twin solid rocket boosters for our SLS rocket are the first elements to be stacked on the mobile launcher inside the VAB. Crews with NASA’s Exploration Ground Systems and contractor Jacobs team completed stacking the boosters in March. Each taller than the Statue of Liberty and adorned with the iconic NASA “worm” logo, the five-segment boosters flank either side of the rocket’s core stage and upper stage. At launch, each booster produces more than 3.6 million pounds of thrust in just two minutes to quickly lift the rocket and spacecraft off the pad and to space.

Bring in the core stage

In between the twin solid rocket boosters is the core stage. The stage has two huge liquid propellant tanks, computers that control the rocket’s flight, and four RS-25 engines. Weighing more than 188,000 pounds without fuel and standing 212 feet, the core stage is the largest element of the SLS rocket. To place the core stage in between the two boosters, teams will use a heavy-lift crane to raise and lower the stage into place on the mobile launcher.

On launch day, the core stage’s RS-25 engines produce more than 2 million pounds of thrust and ignite just before the boosters. Together, the boosters and engines produce 8.8 million pounds of thrust to send the SLS and Orion into orbit.

Add the Launch Vehicle Stage Adapter

Once the boosters and core stage are secured, teams add the launch vehicle stage adapter, or LVSA, to the stack. The LVSA is a cone-shaped element that connects the rocket’s core stage and Interim Cryogenic Propulsion Stage (ICPS), or upper stage. The roughly 30-foot LVSA houses and protects the RL10 engine that powers the ICPS. Once teams bolt the LVSA into place on top of the rocket, the diameter of SLS will officially change from a wide base to a more narrow point — much like a change in the shape of a pencil from eraser to point.

Lower the Interim Cryogenic Propulsion Stage into place

Next in the stacking line-up is the Interim Cryogenic Propulsion Stage or ICPS. Like the LVSA, crews will lift and bolt the ICPS into place. To help power our deep space missions and goals, our SLS rocket delivers propulsion in phases. At liftoff, the core stage and solid rocket boosters will propel Artemis I off the launch pad. Once in orbit, the ICPS and its single RL10 engine will provide nearly 25,000 pounds of thrust to send our Orion spacecraft on a precise trajectory to the Moon.

Nearly there with the Orion stage adapter

When the Orion stage adapter crowns the top of the ICPS, you’ll know we’re nearly complete with stacking SLS rocket for Artemis I. The Orion Stage Adapter is more than just a connection point. At five feet in height, the Orion stage adapter may be small, but it holds and carries several small satellites called CubeSats. After Orion separates from the SLS rocket and heads to the Moon, these shoebox-sized payloads are released into space for their own missions to conduct science and technology research vital to deep space exploration. Compared to the rest of the rocket and spacecraft, the Orion stage adapter is the smallest SLS component that’s stacked for Artemis I.

Top it off

Finally, our Orion spacecraft will be placed on top of our Moon rocket inside the VAB. The final piece will be easy to spot as teams recently added the bright red NASA “worm” logotype to the outside of the spacecraft. The Orion spacecraft is much more than just a capsule built to carry crew. It has a launch abort system, which will carry the crew to safety in case of an emergency, and a service module developed by the European Space Agency that will power and propel the spacecraft during its three-week mission. On the uncrewed Artemis I mission, Orion will check out the spacecraft’s critical systems, including navigation, communications systems, and the heat shield needed to support astronauts who will fly on Artemis II and beyond.

Ready for launch!

The path to the pad requires many steps and check lists. Before Artemis I rolls to the launch pad, teams will finalize outfitting and other important assembly work inside the VAB. Once assembled, the integrated SLS rocket and Orion will undergo several final tests and checkouts in the VAB and on the launch pad before it’s readied for launch.

The Artemis I mission is the first in a series of increasingly complex missions that will pave the way for landing the first woman and the first person of color on the Moon. The Space Launch System is the only rocket that can send NASA astronauts aboard NASA’s Orion spacecraft and supplies to the Moon in a single mission.
