NASA has awarded a total of $1.5 million to two U.S. teams for their novel technology solutions addressing energy distribution, management, and storage as part of the agency’s Watts on the Moon Challenge. The innovations from this challenge aim to support NASA’s Artemis missions, which will establish long-term human presence on the Moon.

This two-phase competition has challenged U.S. innovators to develop breakthrough power transmission and energy storage technologies that could enable long-duration Moon missions to advance the nation’s lunar exploration goals. The final phase of the challenge concluded with a technology showcase and winners’ announcement ceremony Friday at Great Lakes Science Center, home of the visitor center for NASA’s Glenn Research Center in Cleveland.

“Congratulations to the finalist teams for developing impactful power solutions in support of NASA’s goal to sustain human presence on the Moon,” said Kim Krome-Sieja, acting program manager for NASA Centennial Challenges at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “These technologies seek to improve our ability to explore and make discoveries in space and could have implications for improving power systems on Earth.”

The winning teams are:

  • First prize ($1 million): H.E.L.P.S.  (High Efficiency Long-Range Power Solution) of Santa Barbara, California
  • Second prize ($500,000): Orbital Mining Corporation of Golden, Colorado

Four teams were invited to refine their hardware and deliver full system prototypes in the final stage of the competition, and three finalist teams completed their technology solutions for demonstration and assessment at NASA Glenn. The technologies were the first power transmission and energy storage prototypes to be tested by NASA in a vacuum chamber mimicking the freezing temperature and absence of pressure found at the permanently shadowed regions of the Lunar South Pole. The simulation required the teams’ power systems to demonstrate operability over six hours of solar daylight and 18 hours of darkness with the user three kilometers (nearly two miles) away from the power source.

During this competition stage, judges scored the finalists’ solutions based on a Total Effective System Mass (TESM) calculation, which measures the effectiveness of the system relative to its size and weight – or mass – and the total energy provided by the power source. The highest-performing solution was identified based on having the lowest TESM value – imitating the challenges that space missions face when attempting to reduce mass while meeting the mission’s electrical power needs.

Team H.E.L.P.S. (High Efficiency Long-Range Power Solution) from University of California, Santa Barbara, won the grand prize for their hardware solution, which had the lowest mass and highest efficiency of all competitors. The technology also featured a special cable operating at 800 volts and an innovative use of energy storage batteries on both ends of the transmission system. They also employed a variable radiation shield to switch between conserving heat during cold periods and disposing of excess heat during high power modes. The final 48-hour test proved their system design effectively met the power transmission, energy storage, and thermal challenges in the final phase of competition.

Orbital Mining Corporation, a space technology startup, received the second prize for its hardware solution that also successfully completed the 48-hour testwith high performance. They employed a high-voltage converter system coupled with a low-mass cable and a lithium-ion battery.

“The energy solutions developed by the challenge teams are poised to address NASA’s space technology priorities,” said Amy Kaminski, program executive for Prizes, Challenges, and Crowdsourcing in NASA’s Space Technology Mission Directorate at NASA Headquarters in Washington. “These solutions support NASA’s recently ranked civil space shortfalls, including in the top category of surviving and operating through the lunar night.”

During the technology showcase and winners’ announcement ceremony, NASA experts, media, and members of the public gathered to see the finalist teams’ technologies and hear perspectives from the teams’ participation in the challenge. After the winners were announced, event attendees were also welcome to meet NASA astronaut Stephen Bowen.

The Watts on the Moon Challenge is a NASA Centennial Challenge led by NASA Glenn. NASA Marshall Space Flight Center manages Centennial Challenges, which are part of the agency’s Prizes, Challenges, and Crowdsourcing program in the Space Technology Mission Directorate. NASA contracted HeroX to support the administration of this challenge.

NASA Data Helps Protect US Embassy Staff from Polluted Air

United States embassies and consulates, along with American citizens traveling and living abroad, now have a powerful tool to protect against polluted air, thanks to a collaboration between NASA and the U.S. State Department.

Since 2020, ZephAir has provided real-time air quality data for about 75 U.S. diplomatic posts. Now, the public tool includes three-day air quality forecasts for PM2.5, a type of fine particulate matter, for all the approximately 270 U.S. embassies and consulates worldwide. These tiny particles, much smaller than a grain of sand, can penetrate deep into the lungs and enter the bloodstream, causing respiratory and cardiovascular problems.

“This collaboration with NASA showcases how space-based technology can directly impact lives on the ground,” said Stephanie Christel, climate adaptation and air quality monitoring program lead with the State Department’s Greening Diplomacy Initiative. “This is not something the State Department could have done on its own.” For instance, placing air quality monitors at all U.S. diplomatic posts is prohibitively expensive, she explained.

“NASA’s involvement brings not only advanced technology,” she added, “but also a trusted name that adds credibility and reliability to the forecasts, which is invaluable for our staff stationed abroad.”

The forecasts, created using NASA satellite data, computer models, and machine learning, are crucial for U.S. embassies and consulates, where approximately 60,000 U.S. citizens and local staff work. Many of these sites are in regions with few local air quality monitors or early warning systems for air pollution.

“ZephAir’s new forecasting capability is a prime example of NASA’s commitment to using our data for societal benefit,” said Laura Judd, an associate program manager for Health and Air Quality at NASA. “Partnering with the State Department allows us to extend the reach of our air quality data, providing embassies and local communities worldwide with vital information to protect public health.”

Enhancing Health, Safety with NASA Air Quality Data

To manage air pollution exposure, the tool can assist diplomatic staff with decisions on everything from building ventilation to outdoor activities at embassy schools.

For many embassies, especially in regions with severe air pollution, having reliable air quality forecasts is crucial for safeguarding staff and their families, influencing both daily decisions and long-term planning. “Air quality is a top priority for my family as we think about [our next assignment], so having more information is a huge help,” said Alex Lewis, a political officer at the U.S. embassy in Managua, Nicaragua.

Previously, ZephAir only delivered data on current PM2.5 levels using air quality monitors on the ground from about 75 U.S. diplomatic locations and about 50 additional sources. Now, the enhanced tool provides PM2.5 forecasts for all sites, using the Goddard Earth Observing System forward processing (GEOS-FP), a weather and climate computer model. It incorporates data on tiny particles or droplets suspended in Earth’s atmosphere called aerosols from MODIS (Moderate-resolution Imaging Spectroradiometer) on NASA’s Terra and Aqua satellites.

Aerosols are tiny airborne particles that come from both natural sources, like dust, volcanic ash, and sea spray, and from human activities, such as burning fossil fuels. PM2.5 refers to particles or droplets that are 2.5 micrometers or smaller in diameter — about 30 times smaller than the width of a human hair.

“We use the GEOS-FP model to generate global aerosol forecasts,” said Pawan Gupta, of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the lead scientist on the project. “Then we calibrate the forecasts for embassy locations, using historical data and machine learning techniques.”

As of August 2024, the forecasting feature is available on the ZephAir web and mobile platforms.

The new forecasts are about more than just protecting U.S. citizens and local embassy staff; they are also contributing to global action on air quality. The State Department engages with local governments and communities to raise awareness about air quality issues. “These forecasts are a critical part of our strategy to mitigate the impacts of air pollution not only for our personnel but also for the broader community in many regions around the world,” Christel said.

Officials with the Greening Diplomacy Initiative partnered with NASA through the Health and Air Quality Applied Sciences Team  to develop the new forecasts and will continue the collaboration through support from the Satellite Needs Working Group.

Looking ahead, the team aims to expand ZephAir’s capabilities to include ground-level ozone data, another major pollutant that can affect the health of embassy staff and local communities.

Could Stars Hotter Than the Sun Still Support Life?

Universe Today - Fri, 09/20/2024 - 11:22am

Although most potentially habitable worlds orbit red dwarf stars, we know larger and brighter stars can harbor life. One yellow dwarf star, for example is known to have a planet teaming with life, perhaps even intelligent life. But how large and bright can a star be and still have an inhabited world? That is the question addressed in a recent article in the Astrophysical Journal.

Stable main-sequence stars such as the Sun are categorized by color or spectral type, with each type assigned a letter designation. For historical reasons the categories aren’t alphabetical. Red dwarf stars, the coolest stars with the smallest mass, are M type. Then with each brighter, bluer, and more massive category is K, G, F, A, B, and finally O. The Sun falls into the G category as a yellow star. Each spectral type is then broken into smaller sections, numbered 0 – 9. The Sun is G2 star because it is at the warmer end of G-type stars.

As you go up the scale, the potentially habitable zone shifts farther from the star but also gets larger. That makes it more likely for a planet to be in the zone. But larger stars also have shorter lives, which might not give life enough time to evolve on a world. Then there are other factors that can be harmful for life. The largest stars emit a tremendous amount of ionizing radiation, which could strip planets of their atmospheres, or sterilize the surface of a planet. Because of this, the largest stars of the B and O types aren’t likely to harbor life.

How habitable zones differ by spectral type. Credit: NASA, ESA and Z. Levy (STScI)

But what about F-type stars? They are a bit brighter than the Sun and more white than yellow in color. They are also stable for around 4 billion years, which is long enough for life to evolve and thrive. And they also emit more ultraviolet radiation, which may have helped life arise on Earth. What are the odds of a habitable F-type planet?

To answer this question, the team went through the database of known exoplanets. About 80 F-type main-sequence stars are known to have at least one planet. Of those, 18 systems have exoplanets that spend at least part of their orbit in the habitable zone of the star. And in one case, the exoplanet 38 Virginis b, the planet is always in the habitable zone. Statistically around 5% – 20% of F-type stars have potential for life.

What’s interesting about 38 Virginis b is that it is a gas giant about 4 times more massive than Jupiter, so it isn’t likely to be habitable. But it could have Earth-sized moons, similar to the Galilean moons of Jupiter. A world orbiting a Jovian planet could be a perfect home for life.

F-type stars only comprise 3% of main-sequence stars in the Milky Way, and it’s possible that their excess UV light could rule out habitable worlds. But alien astronomers might make similar arguments about G-type stars like the Sun. As this study shows, we shouldn’t rule out the Sun’s brighter cousins in the search for living worlds.
