One of the challenges many teachers face year after year is a sense of working alone. Despite the constant interaction with students many questions often linger: Did the lesson stick? Will students carry this knowledge with them? Will it shape how they see and engage with the world? What can be easy to overlook is that teaching does not happen in isolation. Each classroom, or any other educational setting, is part of a much larger journey that learners travel. This journey extends through a network of educators, where each experience can build on the last. These interconnected networks, known as Connected Learning Ecosystems (CLEs), exist wherever learning happens. At their core, CLEs are the collective of people who contribute to a young person’s growth and education over time.
Educators at the August 2025 Connected Learning Ecosystems Gathering in Orono, ME engaged in discussion around using NASA data in their learning contexts. Recognizing this, NASA’s Science Activation Program launched the Learning Ecosystems Northeast (LENE) project to strengthen and connect regional educator networks across Maine and the broader Northeast. With a shared focus on Science, Technology, Engineering, and Mathematics (STEM), LENE brings together teachers, librarians, 4-H mentors, land trust educators, and many others committed to expanding scientific understanding, deepening data literacy, and preparing youth to navigate a changing planet. To support this work, LENE hosts biannual Connected Learning Ecosystem Gatherings. These multi-day events bring educators together to share progress, celebrate achievements, and plan future collaborations. More than networking, these gatherings reinforce the collective impact educators have, ensuring that their efforts resonate far beyond individual classrooms and enrich the lives of the learners they guide.
“I am inspired by the GMRI staff and participants. I never expected to get to do climate resilience-related work in my current job as a children’s librarian. I am excited to do meaningful and impactful work with what I gain from being part of this the LENE community. This was a very well-run event! Thank you to all!” -anonymous
This year’s Gathering took place August 12 and 13, 2025, in Orono, ME at the University of Maine (a LENE project partner). Nearly 70 educators from across the northeast came together for two amazingly energized days of connection, learning, and future planning. While each event is special, this summer’s Gathering was even more remarkable due to the fact that for, the first time, each workshop was led by an established LENE educator. Either by self-nomination or request from leadership (requiring little convincing), every learning experience shared over the conference days was guided by the thoughtful investigation and real life application of LENE Project Partners, CLE Lead Educators, and community collaborators.
Brian Fitzgerald and Jackie Bellefontaine from the Mount Washington Observatory in New Hampshire, a LENE Project Partner, led the group through a hands-on activity using NASA data and local examples to observe extreme weather. Librarian Kara Reiman guided everyone through the creation and use of a newly established Severe Weather Disaster Prep Kit, including games and tools to manage climate anxiety. Katrina Heimbach, a long time CLE constituent from Western Maine taught how to interpret local data using a creative and fun weaving technique. Because of the established relationship between Learning Ecosystems Northeast and the University of Maine, attendees to the Gathering were able to experience a guided tour through the Advanced Structures and Composites Center and one of its creations, the BioHome3D – the world’s first 3D printed house made entirely with forest-derived, recyclable materials.
Two full days of teachers leading teachers left the entire group feeling energized and encouraged, connected, and centered. The increased confidence in their practices gained by sustained support from their peers allowed these educators to step up and share – embodying the role of Subject Matter Expert. Seeing their colleagues take center stage makes it easier for other educators to envision themselves in similar roles and provides clear guidance on how to take those steps themselves. One educator shared their thoughts following the experience:
“This was my first time attending the LENE conference, and I was immediately welcomed and made to feel ‘part of it all’. I made connections with many of the educators who were present, as well as the LENE staff and facilitators. I hope to connect with my new CLE mates in the near future!” Another participant reported, “I am inspired by the … staff and participants. I never expected to get to do climate resilience-related work in my current job as a children’s librarian. I am excited to do meaningful and impactful work with what I gain from being part of the LENE community. This was a very well-run event! Thank you to all!”
Even with the backing of regional groups, many educators, especially those in rural communities, still struggle with a sense of isolation. The biannual gatherings play an important role in countering that, highlighting the fact that this work is unfolding across the state. Through Connected Learning Ecosystems, educators are able to build and reinforce networks that help close the gaps created by distance and geography.
These Gatherings are part of ongoing programming organized by Learning Ecosystems Northeast, based at the Gulf of Maine Research Institute, that fosters peer communities across the Northeast, through which teachers, librarians, and out-of-school educators can collaborate to expand opportunities for youth to engage in data-driven investigations and integrate in- and out-of-school learning.

Video: 00:01:43 An essential part of ESA’s Space Safety programme is dedicated to getting and keeping Earth’s orbits clean from space debris. In the long run, the Agency aspires to stimulate a true circular economy in space, minimising the impact of spaceflight on Earth and its resources where possible. As part of ESA’s Zero Debris approach, new ESA missions will be designed for safe operations and disposal to stop the creation of new debris by 2030.
ESA has now taken another important step on the road towards sustainability in space with its first in-orbit servicing mission RISE, planned for launch in 2029.
RISE is a commercial in-orbit servicing mission that will demonstrate that it can safely rendezvous and dock to a geostationary client satellite, extending the life of geostationary satellites that need support with attitude and orbit control, but are otherwise in working order.
After verifying that it meets all the performance standards in a first demonstration, prime contractor, operator and co-founder D-Orbit will start commercial life extension services for geostationary satellites.
ESA’s RISE mission marks a promising step towards enhancing in-orbit services and technologies, such as refuelling, refurbishment and assembling – all essential elements for creating a circular economy in space.

NASA satellite data and trainings helped Uruguay create a drought-response tool that its National Water Authority now uses to monitor reservoirs and guide emergency decisions. A similar approach could be applied in the United States and other countries around the world.
From 2018 to 2023, Uruguay experienced its worst drought in nearly a century. The capital city of Montevideo, home to nearly 2 million people, was especially hard hit. By mid-2023, Paso Severino, the largest reservoir and primary water source for Montevideo, had dropped to just 1.7% of its capacity. As water levels declined, government leaders declared an emergency. They began identifying backup supplies and asked: Was there water left in other upstream reservoirs — mainly used for livestock and irrigation — that could help?
That’s when environmental engineer Tiago Pohren and his colleagues at the National Water Authority (DINAGUA – Ministry of Environment) turned to NASA data and trainings to build an online tool that could help answer that question and improve monitoring of the nation’s reservoirs.
“Satellite data can inform everything from irrigation scheduling in the Great Plains to water quality management in the Chesapeake Bay,” said Erin Urquhart, manager of the water resources program at NASA Headquarters in Washington. “NASA provides the reliable data needed to respond to water crises anywhere in the world.”
Learning to Detect Water from Space
The DINAGUA team learned about NASA resources during a 2022 workshop in Buenos Aires, organized by the Interagency Science and Applications Team (ISAT). Led by NASA, the U.S. Army Corps of Engineers, and the U.S. Department of State, the workshop focused on developing tools to help manage water in the La Plata River Basin, which spans multiple South American countries including Uruguay.
At the workshop, researchers from NASA introduced participants to methods for measuring water resources from space. NASA’s Applied Remote Sensing (ARSET) program also provided a primer on remote sensing principles.
DINAGUA team supervisor Jose Rodolfo Valles León asks a question during a 2022 workshop in Buenos Aires. Other members of the Uruguay delegation — Florencia Hastings, Vanessa Erasun Rodríguez de Líma, Vanessa Ferreira, and Teresa Sastre (current Director of DINAGUA) — sit in the row behind. Organization of American States “NASA doesn’t just deliver data,” said John Bolten, NASA’s lead scientist for ISAT and chief of the Hydrological Sciences Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We collaborate with our partners and local experts to translate the data into information that is useful, usable, and relevant. That kind of coordination is what makes NASA’s water programs so effective on the ground, at home and around the world.”
The DINAGUA team brought ideas and provided guidelines to Pohren for a tool that applies Landsat and Sentinel satellite imagery to detect changes in Uruguay’s reservoirs. Landsat, a joint NASA-U.S. Geological Survey mission, provides decades of satellite imagery to track changes in land and water. The Sentinel missions, a part of the European Commission managed Copernicus Earth Observation program and operated by ESA (the European Space Agency), provide complementary visible, infrared, and microwave imagery for surface water assessments.
From a young age, Pohren was familiar with water-related challenges, as floods repeatedly inundated his relatives’ homes in his hometown of Montenegro, Brazil. It was extra motivation for him as he scoured ARSET tutorials and taught himself to write computer code. The result was a monitoring tool capable of estimating the surface area of Uruguay’s reservoirs over time.
A screenshot of the reservoir monitoring tool shows the Paso Severino’s surface water coverage alongside time-series data tracking its variations. Tiago Pohren The tool draws on several techniques to differentiate the surface water extent of reservoirs. These techniques include three optical indicators derived from the Landsat 8 and Sentinel-2 satellites:
Normalized Difference Water Index, which highlights water by comparing how much green and near-infrared light is reflected. Water absorbs infrared light, so it stands out clearly from land. Modified Normalized Difference Water Index, which swaps near-infrared with shortwave infrared to improve the contrast and reduce errors when differentiating between water and built-up or vegetated areas. Automated Water Extraction Index, which combines four types of reflected light — green, near-infrared, and two shortwave infrared bands — to help separate water from shadows and other dark features. From Emergency Tool to Everyday Asset
In 2023, the DINAGUA team used Pohren’s tool to examine reservoirs located upstream from Montevideo’s drinking water intake. But the data told a tough story.
“There was water available in other reservoirs, but it was a very small amount compared to the water demand of the Montevideo metropolitan region,” Pohren said. Simulations showed that even if all of the water were released, most of it would not reach the water intake for Montevideo or the Paso Severino reservoir.
Despite this news, the analysis prevented actions that might have wasted important resources for maintaining productive activities in the upper basin, Pohren said. Then, in August 2023, rain began to refill Uruguay’s reservoirs, allowing the country to declare an end to the water crisis.

Organization of American States Though the immediate water crisis has passed, the tool Pohren created will be useful in the future in Uruguay and around the world. During an ISAT workshop in 2024, he shared his tool with international water resources managers with the hope it could aid their own drought response efforts. And DINAGUA officials still use it to identify and monitor dams, irrigation reservoirs, and other water bodies in Uruguay.
Pohren continues to use NASA training and data to advance reservoir management. He’s currently exploring an ARSET training on how the Surface Water and Ocean Topography (SWOT) mission will further improve the system by allowing DINAGUA to directly measure the height of water in reservoirs. He is also following NASA’s new joint mission with ISRO (the Indian Space Research Organization) called NISAR, which launched on July 30. The NISAR satellite will provide radar data that detects changes in water extent, regardless of cloud cover or time of day. “If a drought happens again,” Pohren said, “with the tools that we have now, we will be much more prepared to understand what the conditions of the basin are and then make predictions.”

NASA Stennis Buffer ZoneNASA / Stennis NASA’s Stennis Space Center is widely known for rocket propulsion testing, especially to support the NASA Artemis program to send astronauts to the Moon to prepare for future human exploration of Mars.
What may not be so widely known is that the site also is a unique federal city, home to more than 50 federal, state, academic, and commercial tenants and serving as both a model of government efficiency and a powerful economic engine for its region.
“NASA Stennis is a remarkable story of vision and innovation,” Center Director John Bailey said. “That was the case 55 years ago when the NASA Stennis federal city was born, and it remains the case today as we collaborate and grow to meet the needs of a changing aerospace world.”
Apollo Years
Nearly four years after its first Saturn V stage test, NASA’s Stennis Space Center faced a crossroads to the future. Indeed, despite its frontline role in supporting NASA’s Apollo lunar effort, it was not at all certain a viable future awaited the young rocket propulsion test site.
In 1961, NASA announced plans to build a sprawling propulsion test site in south Mississippi to support Apollo missions to the Moon. The news was a significant development for the sparsely populated Gulf Coast area.
The new site, located near Bay St. Louis, Mississippi, conducted its first hot fire of a Saturn V rocket stage in April 1966. Saturn V testing progressed steadily during the next years. In fall 1969, however, NASA announced an end to Apollo-related testing, leading to an existential crisis for the young test site.
What was to become of NASA Stennis?
An Expanded Vision
Some observers speculated the location would close or be reduced to caretaker status, with minimal staffing. Either scenario would deliver a serious blow to the families who had re-located to make way for the site and the local communities who had heavily invested in municipal projects to support the influx of workforce personnel.
Such outcomes also would run counter to assurances provided by leaders that the new test site would benefit its surrounding region and involve area residents in “something great.”
For NASA Stennis manager Jackson Balch and others, such a result was unacceptable. Anticipating the crisis, Balch had been working behind the scenes to communicate – and realize – the vision of a multiagency site supporting a range of scientific and technological tenants and missions.
A Pivotal Year
The months following the Saturn V testing announcement were filled with discussions and planning to ensure the future of NASA Stennis. The efforts began to come to fruition in 1970 with key developments:
In early 1970, NASA Administrator Thomas Paine proposed locating a regional environmental center at NASA Stennis. U.S. Sen. John C. Stennis (Mississippi) responded with a message of the president, “urgently requesting” that a National Earth Resources and Environmental Data Program be established at the site. In May 1970, President Richard Nixon offered assurances that an Earth Resources Laboratory would be established at NASA Stennis and that at least two agencies are preparing to locate operations at the site. U.S. congressional leaders earmarked $10 million to enable the location of an Earth Resources Laboratory at NASA Stennis. On July 9, 1970, the U.S. Coast Guard’s National Data Buoy Project (now the National Data Buoy Center) announced it was relocating to NASA Stennis, making it the first federal city tenant. The project arrived onsite two months later on September 9. On Sept. 9, 1970, NASA officially announced establishment of an Earth Resources Laboratory at NASA Stennis. Time to Grow
By the end of 1970, Balch’s vision was taking shape, but it needed time to grow. The final Saturn V test had been conducted in October – with no new campaign scheduled.
A possibility was on the horizon, however. NASA was building a reusable space shuttle vehicle. It would be powered by the most sophisticated rocket engine ever designed – and the agency needed a place to conduct developmental and flight testing expected to last for decades.
Three sites vied for the assignment. Following presentations and evaluations, NASA announced its selection on March 1, 1971. Space shuttle engine testing would be conducted at NASA Stennis, providing time for the location to grow.
A Collaborative Model
By the spring of 1973, preparations for the space shuttle test campaign were progressing and NASA Stennis was on its way to realizing the federal city vision. Sixteen agencies and universities were now located at NASA Stennis.
The resident tenants followed a shared model in which they shared in the cost of basic site services, such as medical, security, and fire protection. The shared model freed up more funding for the tenants to apply towards innovation and assigned mission work. It was a model of government collaboration and efficiency.
As the site grew, leaders then began to call for it to be granted independent status within NASA, a development not long in coming. On June 14, 1974, just more than a decade after site construction began, NASA Administrator James Fletcher announced the south Mississippi location would be renamed National Space Technology Laboratories and would enjoy equal, independent status alongside other NASA centers.
“Something Great”
For NASA Stennis leaders and supporters, independent status represented a milestone moment in their effort to ensure NASA Stennis delivered on its promise of greatness.
There still were many developments to come, including the first space shuttle main engine test and the subsequent 34-year test campaign, the arrival and growth of the U.S. Navy into the predominant resident presence onsite, the renaming of the center to NASA Stennis, and the continued growth of the federal city.
No one could have imagined it all at the time. However, even in this period of early development, one thing was clear – the future lay ahead, and NASA Stennis was on its way.
