St. Louis scientists get $3 million to further moon research

Published

on




Scientists at Washington University and local St. Louis startup, Impossible Sensing, have received a $3 million grant from NASA to develop a new sensor for future missions to the moon.The sensor will be able to measure the chemistry and composition of rocks and soil, providing a better understanding of the moon’s geology, said Jeffery Gillis-Davis, a research professor in WashU’s department of physics, who is leading the development.“It actually fires a laser that creates a little plasma,” he said. “So if you’re looking at it, you’d see a little blueish, grayish light, kind of like lightning.”The instrument then uses a spectrometer to read the light that reflects back, which produces distinct peaks, Gillis-Davis said.“The peaks are uniquely correlated with different elements, just like a fingerprint,” he said. “So we can measure the elemental concentrations of rocks and soils and even ices on the moon.”

The grant from NASA pays for another three years of development to take the sensor from concept to reality via Commercial Lunar Payload Service, said Gillis-Davis. That’s where private companies deliver payloads to the moon for NASA.“We know [this system] works. We know it’ll even work on the moon” Gillis-Davis said. “What we want to do is develop a really small, capable, low-cost, low-energy system that can measure element concentrations with very high fidelity.”Scientists already have some understanding of the elements and minerals that make up the surface of the moon, thanks to the Apollo missions that brought back hundreds of pounds of samples, Gillis-Davis explained. But most of those were collected near the moon’s equator and on the side that faces the Earth, he added.“As we explore the moon’s pole and the far side, we’re definitely going to learn more about the moon as we come across different rock types,” Gillis-Davis said. “That’s what we do as geologists—know how different minerals are mixed together to understand a rock and how it’s put together.”Impossible Sensing founder Pablo Sobron, a co-investigator on the project, added a lot of the understanding of the moon’s composition since the Apollo missions comes from satellites orbiting it.“The problem here is because you are far away, you are limited in your ability to see small features,” he said.Gillis-Davis agrees but this new instrument on a small rover could fill in those gaps.“Sometimes the minerals are really small,” he said. “So we can actually detect those really small millimeter sized minerals that you might not be able to see from a camera image or visually as an astronaut.”This type of data may help scientists answer some of the enduring questions about Earth, like how the planet got its water, Gillis-Davis said. Plate tectonics and weathering mean the Earth’s surface is relatively young compared to the moon’s, which can offer a glimpse into the conditions of the very early solar system, he explained.Gillis-Davis is particularly interested in the ice deposits at the moon’s poles.“If those polar ice deposits formed and may have come out of lunar volcanoes, that would show the moon also formed with water,” he said. “If we see those ice deposits were added later then it’s a better indication that Earth’s water would have come later rather than in its formation.”

Sobron argues this knowledge is also vital to discover given the interest from commercial companies in returning to the moon.“We’re looking at creating a lunar economy,” he said. “We know the moon has all the elements and minerals that we need to build things like rockets and launch pads. We can extract fuels, oxygen [and] water.”The development of this sensing technology can also be helpful for challenges on Earth because of the difficulty of engineering an instrument for space, Sobron said.“One of the hallmarks of space: every pound costs millions of dollars when you launch,” he said. “If you can cut down the volume, the size, the power consumption and how much human input you need to operate it, then you start seeing exponential cost reductions.”And combined with the ability to withstand and operate in low gravity, massive temperature swings and intense radiation exposure means they can have meaningful applications on Earth, Sobron said. Those include things like measuring soil composition at individual plants on a farm or mapping the seafloor and the ecosystems and minerals that exist there, he said.“The throughline is clear to me,” Sobron said. “If we unlock ways to study the moon, to study other planets and space in general, these technologies are automatically applicable to Earth problems.”Both Gillis-Davis and Sobron emphasized the importance of St. Louis being the place where these scientific advancements are developed.“These small companies in St. Louis that can do these types of high tech projects are really unique,” Gillis-Davis said. “It doesn’t have to be Silicon Valley [or] Lincoln Labs in Boston.”Having St. Louis known as a place for high-tech developments for exploration, can inspire local people in college or even elementary school to remain in the region or attract people from across the country, he said.Sobron added it builds on St. Louis’ legacy with space exploration, with the Mcdonnell Aircraft Corporation producing the Mercury and Gemini capsules in the 1950s and 1960s.“This new grant really solidifies the leadership of St. Louis and Washington University in particular in moon science and exploration,” he said.

Economic insecurity and depression are high among young adults

Published

on




Every generation has the sense that what it’s faced has been unique. People born between 1999 and 2005, however, can rightly claim they’ve lived through a great deal already. As the Federal Reserve Bank of St. Louis’ 2024 State of Economic Equity report points out, that swath of young people has already lived through recent instances of historic economic precarity: the COVID-19 recession (aka the Great Lockdown), and high inflation plus “the tightest labor market since World War II.”Ana Hernandez Kent is a senior researcher who’s part of the Institute of Economic Equity team behind the St. Louis Fed report. She told St. Louis on the Air those phenomena have contributed to a troubling number of “disconnected” 18-24 year olds who’re not working or in school, and comparatively high rates of depression.“They’re not acquiring retirement savings. They’re not acquiring savings to save for a house, a downpayment, or even future education. It’s concerning because they’re not potentially building for their future financial stability,” Kent said. “Depression isn’t just an isolated mental condition… it has an impact on the economy if they are perhaps staying out of either education or having a job because they’re depressed,” Kent continued. “Or if they have a job, we know depression and other mental illnesses are more likely to [cause] people to have lower productivity, to take days off. So [mental health] has a wider, broad spread economic impact.”The 2024 report also shows disparities by race in how secure young adults feel about their financial well being. While about 75% of white and Asian young adults said they felt they were doing “at least OK financially,” just over 50% of Black and Hispanic young adults reported the same. Kent said capacity to handle a $400 emergency expense illustrates how that disparity can show up in everyday life.“If you go to the emergency room and you don’t have health insurance, that’s going to blow that [$400] out of the water, and I have a car repair that’s needed, that’s likely going to be more than that. The fact that so many young adults – especially Black and Latino young adults – said they would be unable to handle this kind of expense, that’s very concerning.”Kent said it’s important to focus on 18-24 year olds because young adults are important to the economy at large.“If we’re not supporting these young adults, particularly by race, ethnicity, by gender — companies are missing out on a lot of that potential future leadership,” she said. “They’re not going to be building retirement savings, they’re not going to be building savings to be able to pay a down payment on a house…. So the economy as a whole is not gaining from that, leaving economic potential on the table.”To hear more about how factors like race and gender affect young people’s actual and perceived economic security and what practical support can do to help disconnected young folks gain stability, listen to St. Louis on the Air on Apple Podcast or Spotify, or click the play button below.

St. Louis families say they are grateful for $500 monthly checks

Published

on




Participants in St. Louis’ guaranteed basic income program say they appreciate the safety net the effort has provided.Five of the 540 recipients met Wednesday with Mayor Tishaura Jones and Treasurer Adam Layne to share how they are spending the money and what other resources the city can provide. The program uses $5 million in federal COVID relief funds, plus a $1 million donation from Jack Dorsey to give families $500 monthly checks.To be eligible for the program, families had to live in the city and be the parent or legal guardian of a minor enrolled in a city public or charter school. They could also make no more than 170% of the federal poverty level, which is about $53,000 for a family of four.“We were very specific and intentional about the families we wanted to reach, which were families who were too rich for benefits, but too poor for anything else,” Jones said.The participants can spend the money however they want. One mother who attended the roundtable uses the check to pay for groceries. The funds help another work fewer hours, giving her more time to spend with her daughter, who will be 5 in July.Travious Brooks is using his share to rebuild savings that were wiped out during the COVID-19 pandemic.“My kids are wanting to go on a vacation, so we’re saving up to do that,” he said.He also needs to make repairs to his house, which is more than 120 years old.

St. Louis Public RadioTravious Brooks says he wants to save his money to take his kids on vacation.

All five of the roundtable’s participants said they are glad for the extra help. But they also expressed a need for things like safe transportation for children, more resources for small businesses, and financial literacy classes.“There are a lot of resources in the city, and sometimes they’re not all coordinated,” Layne said. “We’re working on trying to get a resource hub so one place where people can go to our city site, here are all the resources, they’re all connected.”Funding for the program is only available through mid-2025 and Brooks said that was on his mind as he thought about how to use his share.“That was one of the reasons, not knowing the longevity of the program, that I would rather just sit on the funds and have something in the event that anything happened I had something built up,” he said.Jones said she is looking for ways to extend and expand the program.

Tech job listings decline puts focus on St. Louis startups

Published

on




The effort to substantially grow the region’s technology workforce is facing stiff headwinds.St. Louis is dealing with some of the national employment trends in the sector, like layoffs and companies cutting back on hiring new positions.From 2022 and 2023, the total number of active job listings for tech positions dropped 45%, according to a March report from TechSTL, the region’s tech council. The report also finds the St. Louis region had steeper drops in active listings compared to the U.S. as a whole in that same time period.As stark as this news was for TechSTL Executive Director Emily Hemingway, it also offered a sense of relief, she said.“When this [report] came out, it was really validating for all of us because we had seen in life, in reality, that things had shifted,” Hemingway said.She cites two culprits for the current contraction: an end to the pandemic hiring spree in tech and the explosive growth of artificial intelligence prompting some companies to become leaner.While the report found the number of active job listings dropped dramatically between 2022 and 2023, overall employment in the local tech industry ticked up slightly, by 2%.This comes as the U.S. Bureau of Labor Statistics anticipates some tech-sector occupations like software developers, information security analysts and data scientists, will grow as much as 35% by 2032 compared to about 3% growth for all occupations in the country.Hemingway said that means the underlying skills for a technology-focused role are still in demand, just maybe not at a large firm.“When you have significantly fewer jobs, you can’t be dependent on our large anchor institutions or corporate partners to really drive the workforce,” Hemingway said. “These jobs that are being cut are largely in these larger hiring agencies.”She said the St. Louis region needs to prioritize the development and growth of local startups and entrepreneurs as a way to support the existing tech talent in the region.“If we can’t find these folks a good way to make money in St. Louis, they will either change their industry or they will change their town,” Hemingway said. “It is a race to support what we have here and give them a reason to stay in St. Louis.”

‘A lot of fluff in the startup ecosystem’An innovative idea typically forms the basis of new startups, but there can be a downside to focusing too much on pitching them, said Christian Johnson, who runs the geospatial startup Metis Analytics, which provides workflow management software for intelligence analysts.In the 8½ years that Johnson’s been involved in the local startup scene, he said he’s seen some organizations catering to startups favor pitching and promotion over concepts like how to build and scale a new venture.“There’s a lot of fluff in the startup ecosystem,” he said. “It becomes a fashion show basically, instead of it being about can you actually build a product that people want and that will buy from you?”Johnson also runs Founders Lounge, a weekly forum where entrepreneurs of any experience level can discuss their ideas and any obstacles they’ve faced. It also has events that bring in speakers from other cities who shed light on marketing, sales and the technical sides of a business, like choosing a cloud database or how to incorporate large language models into an application, he said.“Just different things that will help move the needle in your business that actually do help,” Johnson said.Spaces for these kinds of interactions are vital, yet lacking in St. Louis, he said, that adding other markets in the U.S. have established places like these.“This is not something that is foreign but something that is super powerful that we’re bringing to St. Louis,” he said.

Financing and customersBeyond more programming to help startups with their business strategy, there’s the sticking point of securing local capital or customers that will invest in or buy a local company’s product.It’s something Arch Grants specifically looks for when vetting the companies it eventually supports, said Executive Director Gabe Angieri. The nonprofit awards grants to companies with high growth potential in St. Louis that are either already located in the region or that will relocate here, he said.“We want companies that see their long-term path to success in St. Louis and this region,” he said. “We put a high barrier to entry on that.”It helps when a startup, local or otherwise, can clearly articulate potential partners, customers or when it can point to people in the St. Louis region who have weighed in on its business plan or innovation, Angieri said. Locating capital and customers are frequent challenges for new ventures in the region, he added.“St. Louis is an extraordinarily generous city — there’s a lot of wealth in this region,” Angieri said. “It is not the most adventurous when it comes to investing in early-stage startups. And it is a high-risk endeavor, no question about it.”There is a push at the state level for tax credits for angel investing that could entice more early-stage investing. But even in the local biosciences sector, which has examples of successful startups that are now standalone companies or were acquired, lots of capital can be hard to come by.“There’s just fewer examples of people taking giant home run swings and succeeding,” said Tom Cohen, chief operating officer at Panome Bio, a local biotech startup.This can push local startups to look for capital or customers elsewhere, likely from the coasts, and that can leave startups asking, “Why am I here?” if their financial support is elsewhere, Angieri said.One solution he sees is in some of the existing large corporations in St. Louis working directly with local startups in addition to the dollars they already dedicate to organizations like Arch Grants, he said.“It’s shifting from a mindset of community-based philanthropy to a more risk-tolerant approach,” Angieri said. “To see the solutions and the innovations come out of the startup sector as viable options as you seek to address pain points in your own companies.”If local corporations started dedicating a portion of their budget to pilot with startups in St. Louis, it could unlock considerable growth for small to midsize ventures in the region, he said.

‘Right now we’re whispering’Entrepreneurs are also responsible for driving this shift in perspective for local companies, argues Chris Ocasio, a server and bartender who’s recently started developing apps.“If we want them to listen, then we have to speak,” he said. “And right now we’re whispering.”When Ocasio first decided to pursue his own venture less than a year ago, he said he was struck by the level of support he received.“Two years ago, a year ago, I had no idea there was this type of ecosystem in St. Louis,” he said. “Everyone was excited to see someone hungry to get into the entrepreneurial space.”Ocasio argues not enough people or companies in the broader St. Louis community are aware of the innovations people like him are working on or how they can get involved in the community if they wanted to.“There’s no TikTok’s about this, you know? Like why can’t we do that,” he said. “We need to show that pride and get St. Louis talking about the fact that there’s innovators here, [that] we’re hungry [and] going to make it happen.”

National Geospatial Intelligence AgencyThe exterior of the new National Geospatial-Intelligence Agency in north St. Louis. The agency has plans to collaborate with more outsider organizations, academic institutions and private industry when its new headquarters in St. Louis fully opens in 2026.

A blueprint for successLeaders across St. Louis don’t have to look far for a potential blueprint on how to respond to the current job environment in the technology sector. The biosciences sector experienced a similar contraction about 20 years ago, said Justin Raymundo, BioSTL’s director of regional workforce strategy for the bioscience sector.“In the early 2000s, we really didn’t have what we would call a thriving entrepreneurial ecosystem or an innovation economy,” he said. “We focused particularly on having large corporations or large academic institutions.”St. Louis saw large companies leave the area or get acquired by firms outside the region, Raymundo said. The strategic response to this and the urban depopulation of the time was to create the Coalition of Plant Live Sciences (the precursor to BioSTL) that would focus on developing an ecosystem to support homegrown innovation in the biosciences and cushion against corporate downsizings, he explained.Two decades later, that strategy has paid off and led to key drivers of innovation in the Cortex Innovation District, BioGenerator Ventures, a dedicated fund for investing in and building biotech startups, and other markers of a healthy startup system where new ventures are making successful exits, he added.“That’s a story of how anchors came together in this community at a point when we really needed to invest,” Raymundo said.But it wasn’t cheap or necessarily easy, he added.“What we’re demystifying now is that a lot of this requires investment, particularly philanthropic investment, state and local investment, private-sector investment,” Raymundo said. “We’ve reached this point in our region over 20 years of a lot of patient capital and commitment.”Johnson, of Metis Analytics, said it’s worth it for St. Louis to make similar pushes now for other sectors like geospatial or artificial intelligence.“We have to do that,” he said. “There are more geospatial startups that are coming here from out of town. But also there needs to be more geospatial startups that are starting from here.”The National Geospatial Intelligence Agency has plans to collaborate with more outsider organizations, academic institutions and private industry when its new headquarters in St. Louis fully opens in 2026.It could create similar conditions in the biotech sector now, where ideas can spin out into new ventures, said Cohen with Panome Bio.“That seems like something that could really blow up,” he said. “And could be the nucleus that creates a whole new sector. We could become the space to build geospatial companies.”
