Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Double Asteroid Redirection Test required extreme precision in mission planning to achieve its mission of impacting an asteroid. The founders of Continuum Space worked on astrodynamics relating to this mission, which they used to inform their product.NASA Planning space missions is a very involved process, ensuring orbits are lined up and spacecraft have enough fuel is imperative to the long-term survival of orbital assets. Continuum Space Systems Inc. of Pasadena, California, produces a cloud-based platform that gives mission planners everything they need to certify that their space resources can accomplish their goals.
Continuum’s story begins at NASA’s Jet Propulsion Laboratory in Southern California. Loic Chappaz, the company’s co-founder, started at JPL as an intern working on astrodynamics related to NASA’s Double Asteroid Redirection Test. There he met Leon Alkalai, a JPL technical fellow who spent his 30-year career at the center planning deep space missions. After Alkalai retired from NASA, he founded Mandala Space Ventures, a startup that explored several avenues of commercial space development. Chappaz soon became Mandala’s first employee, but to plan their future, Mandala’s leadership began thinking about the act of planning itself.
Because the staff had decades of combined experience at JPL, they knew the center had the building blocks for the software they needed. After licensing several pieces of software from JPL, the company began building planning systems that were highly adaptable to any space mission they could come up with. Mandala eventually evolved into a venture firm that incubated space-related startups. However, because Mandala had invested considerably in developing mission-planning tools, further development could be performed by a new company, and Continuum was fully spun off from Mandala in 2021.
Continuum’s platform includes several features for mission planners, such as plotting orbital maneuvers and risk management evaluations. Some of these are built upon software licensed from the Jet Propulsion Laboratory.Continuum Space Systems Inc. Continuum’s tools are designed to take a space mission from concept to completion. There are three different components to their “mission in a box” — design, build and test, and mission operations. The base of these tools are several pieces of software developed at NASA. As of 2024, several space startups have begun planning missions with Continuum’s NASA-inspired software, as well as established operators of satellite constellations. From Continuum to several startups, NASA technologies continue to prove a valuable foundation for the nation’s space economy.

NASA’s Cloud-based Confluence Software Helps Hydrologists Study Rivers on a Global Scale
The Paraná River in northern Argentina. Confluence, which is open-source and free to use, allows researchers to estimate river discharge and suspended sediment levels in Earth’s rivers at a global scale. NASA/ISS Rivers and streams wrap around Earth in complex networks millions of miles long, driving trade, nurturing ecosystems, and stocking critical reserves of freshwater.
But the hydrologists who dedicate their professional lives to studying this immense web of waterways do so with a relatively limited set of tools. Around the world, a patchwork of just 3,000 or so river gauge stations supply regular, reliable data, making it difficult for hydrologists to detect global trends.
“The best way to study a river,” said Colin Gleason, Armstrong Professional Development Professor of Civil and Environmental Engineering at the University of Massachusetts, Amherst, “is to get your feet wet and visit it yourself. The second best way to study a river is to use a river gauge.”
Now, thanks to Gleason and a team of more than 30 researchers, there’s another option: ‘Confluence,’ an analytic collaborative framework that leverages data from NASA’s Surface Water and Ocean Topography (SWOT) mission and the Harmonized Landsat Sentinel-2 archive (HLS) to estimate river discharge and suspended sediment levels in every river on Earth wider than 50 meters. NASA’s Physical Oceanography Distributed Active Archive Center (PO.DAAC) hosts the software, making it open-source and free for users around the world.
By incorporating both altimetry data from SWOT which informs discharge estimates, and optical data from HLS, which informs estimates of suspended sediment data, Confluence marks the first time hydrologists can create timely models of river size and water quality at a global scale. Compared to existing workflows for estimating suspended sediment using HLS data, Confluence is faster by a factor of 30.
I can’t do global satellite hydrology without this system. Or, I could, but it would be extremely time consuming and expensive.
Colin Gleason
Nikki Tebaldi, a Cloud Adoption Engineer at NASA’s Jet Propulsion Laboratory (JPL) and Co-Investigator for Confluence, was the lead developer on this project. She said that while the individual components of Confluence have been around for decades, bringing them together within a single, cloud-based processing pipeline was a significant challenge.
“I’m really proud that we’ve pieced together all of these different algorithms, got them into the cloud, and we have them all executing commands and working,” said Tebaldi.
Suresh Vannan, former manager of PO.DAAC and a Co-Investigator for Confluence, said this new ability to produce timely, global estimates of river discharge and quality will have a huge impact on hydrological models assessing everything from the health of river ecosystems to snowmelt.
“There are a bunch of science applications that river discharge can be used for, because it’s pretty much taking a snapshot of what the river looks like, how it behaves. Producing that snapshot on a global scale is a game changer,” said Vannan.
While the Confluence team is still working with PO.DAAC to complete their software package, users can currently access the Confluence source code here. For tutorials, manuals, and other user guides, visit the PO.DAAC webpage here.
All of these improvements to the original Confluence algorithms developed for SWOT were made possible by NASA’s Advanced Intelligent Systems Technology (AIST) program, a part of the agency’s Earth Science Technology Office (ESTO), in collaboration with SWOT and PO.DAAC.

A video taken by an airline passenger reportedly during a commercial flight over the UK shows what seem to be two figures standing on a layer of clouds.
The intriguing footage has sparked a wave of speculation online. While some viewers suggest the figures could be supernatural beings, closer analysis of the footage reveals additional shapes emerging through the clouds as the camera pans from left to right, image below.
This has led others to theorize that the "figures" might actually be exhaust stacks or other tall structures releasing steam, breaking through a fog layer and creating an illusion of human-like forms.
Rather than supernatural entities, the phenomenon is more likely an example of pareidolia, a psychological tendency to perceive familiar shapes, such as faces or figures, in random patterns.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This image shows an aviation version of a smartphone navigation app that makes suggestions for an aircraft to fly an alternate, more efficient route. The new trajectories are based on information available from NASA’s Digital Information Platform and processed by the Collaborative Departure Digital Rerouting tool.NASA Just like your smartphone navigation app can instantly analyze information from many sources to suggest the best route to follow, a NASA-developed resource is now making data available to help the aviation industry do the same thing.
To assist air traffic managers in keeping airplanes moving efficiently through the skies, information about weather, potential delays, and more is being gathered and processed to support decision making tools for a variety of aviation applications.
Appropriately named the Digital Information Platform (DIP), this living database hosts key data gathered by flight participants such as airlines or drone operators. It will help power additional tools that, among other benefits, can save you travel time.
Ultimately, the aviation industry… and even the flying public, will benefit from what we develop.
Swati Saxena
NASA Aerospace Engineer
“Through DIP we’re also demonstrating how to deliver digital services for aviation users via a modern cloud-based, service-oriented architecture,” said Swati Saxena, DIP project manager at NASA’s Ames Research Center in California.
The intent is not to compete with others. Instead, the hope is that industry will see DIP as a reference they can use in developing and implementing their own platforms and digital services.
“Ultimately, the aviation industry – the Federal Aviation Administration, commercial airlines, flight operators, and even the flying public – will benefit from what we develop,” Saxena said.
The platform and digital services have even more benefits than just saving some time on a journey.
For example, NASA recently collaborated with airlines to demonstrate a traffic management tool that improved traffic flow at select airports, saving thousands of pounds of jet fuel and significantly reducing carbon emissions.
Now, much of the data gathered in collaboration with airlines and integrated on the platform is publicly available. Users who qualify can create a guest account and access DIP data at a new website created by the project.
It’s all part of NASA’s vision for 21st century aviation involving revolutionary next-generation future airspace and safety tools.
Managing Future Air Traffic
During the 2030s and beyond, the skies above the United States are expected to become much busier.
Facing this rising demand, the current National Airspace System – the network of U.S. aviation infrastructure including airports, air navigation facilities, and communications – will be challenged to keep up. DIP represents a key piece of solving that challenge.
NASA’s vision for future airspace and safety involves new technology to create a highly automated, safe, and scalable environment.
What this vision looks like is a flight environment where many types of vehicles and their pilots, as well as air traffic managers, use state-of-the-art automated tools and systems that provide highly detailed and curated information.
These tools leverage new capabilities like machine learning and artificial intelligence to streamline efficiency and handle the increase in traffic expected in the coming decades.
Digital Services Ecosystem in Action
To begin implementing this new vision, our aeronautical innovators are evaluating their platform, DIP, and services at several airports in Texas. This initial stage is a building block for larger such demonstrations in the future.
“These digital services are being used in the live operational environment by our airline partners to improve efficiency of the current airspace operations,” Saxena said. “The tools are currently in use in the Dallas/Fort Worth area and will be deployed in the Houston airspace in 2025.”
The results from these digital tools are already making a difference.
Proven Air Traffic Results
During 2022, a NASA machine learning-based tool named Collaborative Digital Departure Rerouting, designed to improve the flow of air traffic and prevent flight delays, saved more than 24,000 lbs. (10,886 kg.) of fuel by streamlining air traffic in the Dallas area.
If such tools were used across the entire country, the improvements made in efficiency, safety, and sustainability would make a notable difference to the flying public and industry.
“Continued agreements with airlines and the aviation industry led to the creation and expansion of this partnership ecosystem,” Saxena said. “There have been benefits across the board.”
DIP was developed under NASA’s Airspace Operations and Safety Program.
