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.

Years ago, physicist Dr. John Brandenburg stated that there is evidence of two nuclear explosions on Mars. These explosions could have been caused by thermonuclear bombs.
Remnants of an ancient city on Mars destroyed by thermonuclear attack.
Evidence supporting this theory includes the presence of nuclear isotopes in the Martian atmosphere and the detection of a thin layer of substances such as uranium, thorium, and radioactive potassium on the surface of Mars.
The absence of craters at the sites indicates that the bombs were likely detonated above ground in an air blast, which worsens the global fallout but dampens the immediate ground impact. Conversely, if detonated on the ground, the local devastation is immense but the global impact is minimized. Regardless, these explosions were powerful enough to cause a global catastrophe and significantly alter Mars' climate. According to Brandenburg, the nuclear attack apparently wiped out two races: the Cydonians and Utopians.
The MRO HiRISE image ESP_019103_1460 shows the "Atlantic Chaos," and a closer examination reveals a city that was almost destroyed by the thermonuclear explosions. Amid the ruins of destroyed buildings and towering structures, a largely intact dome-shaped structure is visible (See image below.)
The remnants of this city suggest that Mars was once inhabited by intelligent species like the Cydonians and Utopians, who lived there under conditions similar to those on Earth. This also serves as evidence that far more advanced civilizations may have existed for millions of years and possessed the capability to annihilate all life on a planet using thermonuclear bombs, among other means.

The Serpens Nebula from NASA’s James Webb Space Telescope. Alignment of bipolar jets confirms star formation theories
For the first time, a phenomenon astronomers have long hoped to directly image has been captured by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam). In this stunning image of the Serpens Nebula, the discovery lies in the northern area (seen at the upper left) of this young, nearby star-forming region.
Astronomers found an intriguing group of protostellar outflows, formed when jets of gas spewing from newborn stars collide with nearby gas and dust at high speeds. Typically these objects have varied orientations within one region. Here, however, they are slanted in the same direction, to the same degree, like sleet pouring down during a storm.
Image: Serpens Nebula (NIRCam)
In this image of the Serpens Nebula from NASA’s James Webb Space Telescope, astronomers found a grouping of aligned protostellar outflows within one small region (the top left corner). Serpens is a reflection nebula, which means it’s a cloud of gas and dust that does not create its own light, but instead shines by reflecting the light from stars close to or within the nebula. The discovery of these aligned objects, made possible due to Webb’s exquisite spatial resolution and sensitivity in near-infrared wavelengths, is providing information into the fundamentals of how stars are born.
“Astronomers have long assumed that as clouds collapse to form stars, the stars will tend to spin in the same direction,” said principal investigator Klaus Pontoppidan, of NASA’s Jet Propulsion Laboratory in Pasadena, California. “However, this has not been seen so directly before. These aligned, elongated structures are a historical record of the fundamental way that stars are born.”
So just how does the alignment of the stellar jets relate to the rotation of the star? As an interstellar gas cloud crashes in on itself to form a star, it spins more rapidly. The only way for the gas to continue moving inward is for some of the spin (known as angular momentum) to be removed. A disk of material forms around the young star to transport material down, like a whirlpool around a drain. The swirling magnetic fields in the inner disk launch some of the material into twin jets that shoot outward in opposite directions, perpendicular to the disk of material.
In the Webb image, these jets are signified by bright clumpy streaks that appear red, which are shockwaves from the jet hitting surrounding gas and dust. Here, the red color represents the presence of molecular hydrogen and carbon monoxide.
“This area of the Serpens Nebula – Serpens North – only comes into clear view with Webb,” said lead author Joel Green of the Space Telescope Science Institute in Baltimore. “We’re now able to catch these extremely young stars and their outflows, some of which previously appeared as just blobs or were completely invisible in optical wavelengths because of the thick dust surrounding them.”
Astronomers say there are a few forces that potentially can shift the direction of the outflows during this period of a young star’s life. One way is when binary stars spin around each other and wobble in orientation, twisting the direction of the outflows over time.
Stars of the Serpens
The Serpens Nebula, located 1,300 light-years from Earth, is only one or two million years old, which is very young in cosmic terms. It’s also home to a particularly dense cluster of newly forming stars (~100,000 years old), seen at the center of this image. Some of these stars will eventually grow to the mass of our Sun.
“Webb is a young stellar object-finding machine,” Green said. “In this field, we pick up sign posts of every single young star, down to the lowest mass stars.”
“It’s a very complete picture we’re seeing now,” added Pontoppidan.
So, throughout the region in this image, filaments and wisps of different hues represent reflected starlight from still-forming protostars within the cloud. In some areas, there is dust in front of that reflection, which appears here with an orange, diffuse shade.
This region has been home to other coincidental discoveries, including the flapping “Bat Shadow,” which earned its name when 2020 data from NASA’s Hubble Space Telescope revealed a star’s planet-forming disk to flap, or shift. This feature is visible at the center of the Webb image.
Future Studies
The new image, and serendipitous discovery of the aligned objects, is actually just the first step in this scientific program. The team will now use Webb’s NIRSpec (Near-Infrared Spectrograph) to investigate the chemical make-up of the cloud.
The astronomers are interested in determining how volatile chemicals survive star and planet formation. Volatiles are compounds that sublimate, or transition from a solid directly to a gas, at a relatively low temperature – including water and carbon monoxide. They’ll then compare their findings to amounts found in protoplanetary disks of similar-type stars.
“At the most basic form, we are all made of matter that came from these volatiles. The majority of water here on Earth originated when the Sun was an infant protostar billions of years ago,” Pontoppidan said. “Looking at the abundance of these critical compounds in protostars just before their protoplanetary disks have formed could help us understand how unique the circumstances were when our own solar system formed.”
These observations were taken as part of General Observer program 1611. The team’s initial results have been accepted in the Astrophysical Journal.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).
