Architecture Concept Review attendees listen to welcome remarks from NASA leadership on Nov. 14, 2023, at NASA’s Kennedy Space Center in Florida. Attendees included representatives from all of NASA’s centers, leaders from all of NASA’s mission directorates, various technical authorities, and other stakeholders across the agency. NASA/Kim Shifflett NASA hosted its second annual Architecture Concept Review in mid-November, bringing together leaders from across the agency to discuss progress on and updates to NASA’s Moon to Mars architecture since NASA released outcomes from its first such review in April.
As NASA builds a blueprint for human exploration throughout the solar system for the benefit of humanity, the agency has established the internal Architecture Concept Review process to help align NASA’s Moon to Mars exploration strategy and codify the supporting architecture through robust analysis. Through this evolutionary process, NASA continuously updates its roadmap for crewed exploration, setting humanity on a path to the Moon, Mars, and beyond.
NASA leadership gives opening remarks at the review. From left to right: Casey Swails, deputy associate administrator; Catherine Koerner, deputy associate administrator for the Exploration Systems Development Mission Directorate; Jim Free, associate administrator for the Exploration Systems Development Mission Directorate; and Pam Melroy, deputy administrator. NASA/Kim Shifflett “Our yearly strategic analysis cycle informs architecture decisions by identifying technology gaps, performing trade studies, and soliciting feedback from industry, academia, and the international community,” said Catherine Koerner, deputy associate administrator for NASA’s Exploration Systems Development Mission Directorate. “This year’s review focused on identifying the foundational decisions needed for a crewed mission to Mars and adding more detail to how we break down our objectives for long-term lunar exploration into specific architectural elements.”
During the review, NASA also began to define potentially viable and affordable opportunities for new programs and projects that close capability gaps.
NASA will share the results of this year’s Architecture Concept Review cycle early next year. This will include an update to the agency’s Architecture Definition Document and associated white papers, which provide additional detail on results from this year’s strategic analysis cycle.
Both the updated Architecture Definition Document and white papers will be made available on NASA’s Moon to Mars architecture webpages.

NASA Orbiter Snaps Stunning Views of Mars Horizon
This unusual view of the horizon of Mars was captured by NASA’s Odyssey orbiter using its THEMIS camera, in an operation that took engineers three months to plan. It’s taken from about 250 miles above the Martian surface – about the same altitude at which the International Space Station orbits Earth.NASA/JPL-Caltech/ASU The Odyssey orbiter captured clouds and dust in the Red Planet’s skies, along with one of its two tiny moons.
Astronauts often react with awe when they see the curvature of the Earth below the International Space Station. Now Mars scientists are getting a taste of what that’s like, thanks to NASA’s 2001 Mars Odyssey orbiter, which completed its 22nd year at the Red Planet last month.
The spacecraft captured a series of panoramic images that showcases the curving Martian landscape below gauzy layers of clouds and dust. Stitched end to end, the 10 images offer not only a fresh, and stunning, view of Mars, but also one that will help scientists gain new insights into the Martian atmosphere.
The spacecraft took the images in May from an altitude of about 250 miles (400 kilometers) – the same altitude at which the space station flies above Earth.
Laura Kerber, deputy project scientist for NASA’s Mars Odyssey orbiter, explains how and why the spacecraft captured a view of the Red Planet similar to the International Space Station’s view of Earth. Credit: NASA/JPL-Caltech “If there were astronauts in orbit over Mars, this is the perspective they would have,” said Jonathon Hill of Arizona State University, operations lead for Odyssey’s camera, called the Thermal Emission Imaging System, or THEMIS. “No Mars spacecraft has ever had this kind of view before.”
How It Was Done
The reason why the view is so uncommon is because of the challenges involved in creating it. Engineers at NASA’s Jet Propulsion Laboratory in Southern California, which manages the mission, and Lockheed Martin Space, which built Odyssey and co-leads day-to-day operations, spent three months planning the THEMIS observations. The infrared camera’s sensitivity to warmth enables it to map ice, rock, sand, and dust, along with temperature changes, on the planet’s surface.
It can also measure how much water ice or dust is in the atmosphere, but only in a narrow column directly below the spacecraft. That’s because THEMIS is fixed in place on the orbiter; it usually points straight down.
The mission wanted a more expansive view of the atmosphere. Seeing where those layers of water-ice clouds and dust are in relation to each other – whether there’s one layer or several stacked on top of each other – helps scientists improve models of Mars’ atmosphere.
“I think of it as viewing a cross-section, a slice through the atmosphere,” said Jeffrey Plaut, Odyssey’s project scientist at JPL. “There’s a lot of detail you can’t see from above, which is how THEMIS normally makes these measurements.
NASA’s 2001 Mars Odyssey orbiter used its THEMIS camera to capture this series of images of Phobos, one of the Red Planet’s two tiny moons.NASA/JPL-Caltech Because THEMIS can’t pivot, adjusting the angle of the camera requires adjusting the position of the whole spacecraft. In this case, the team needed to rotate the orbiter almost 90 degrees while making sure the Sun would still shine on the spacecraft’s solar panels but not on sensitive equipment that could overheat. The easiest orientation turned out to be one where the orbiter’s antenna pointed away from Earth. That meant the team was out of communication with Odyssey for several hours until the operation was complete.
The Odyssey mission hopes to take similar images in the future, capturing the Martian atmosphere across multiple seasons.
Over the Moon
To make the most of their effort, the mission also captured imagery of Mars’ little moon Phobos. This marks the seventh time in 22 years that the orbiter has pointed THEMIS at the moon in order to measure temperature variations across its surface.
“We got a different angle and lighting conditions of Phobos than we’re used to,” Hill said. “That makes it a unique part of our Phobos dataset.”
The new imagery provides insight into the composition and physical properties of the moon. Further study could help settle a debate over whether Phobos, which measures about 16 miles (25 kilometers) across, is a captured asteroid or an ancient chunk of Mars that was blasted off the surface by an impact.
NASA is participating with JAXA (Japan Aerospace Exploration Agency) in a sample return mission to Phobos and its sister moon, Deimos, called Mars Moon eXplorer, or MMX. Odyssey’s Phobos imagery will be helpful to scientists working on both Odyssey as well as MMX.

NASA Uses Two Worlds to Test Future Mars Helicopter Designs
This video combines two perspectives of the 59th flight of NASA’s Ingenuity Mars Helicopter. Video on the left was captured by the Mastcam-Z on NASA’s Perseverance Mars rover; the black-and-white video on the right was taken by Ingenuity’s downward-pointing Navcam. The flight occurred Sept 16. NASA/JPL-Caltech/ASU/MSSS Engineers will go beyond the ends of the Earth to find more performance for future Mars helicopters.
For the first time in history, two planets have been home to testing future aircraft designs. On this world, a new rotor that could be used with next-generation Mars helicopters was recently tested at NASA’s Jet Propulsion Laboratory in Southern California, spinning at near-supersonic speeds (0.95 Mach). Meanwhile, the agency’s Ingenuity Mars Helicopter has achieved new altitude and airspeed records on the Red Planet in the name of experimental flight testing.
“Our next-generation Mars helicopter testing has literally had the best of both worlds,” said Teddy Tzanetos, Ingenuity’s project manager and manager for the Mars Sample Recovery Helicopters. “Here on Earth, you have all the instrumentation and hands-on immediacy you could hope for while testing new aircraft components. On Mars, you have the real off-world conditions you could never truly re-create here on Earth.” That includes a whisper-thin atmosphere and significantly less gravity than on Earth.
The next-generation carbon fiber rotor blades being tested on Earth are almost 4 inches (more than 10 centimeters) longer than Ingenuity’s, with greater strength and a different design. NASA thinks these blades could enable bigger, more capable Mars helicopters. The challenge is, as the blade tips approach supersonic speeds, vibration-causing turbulence can quickly get out of hand.
To find a space big enough to create a Martian atmosphere on Earth, engineers looked to JPL’s 25-foot wide, 85-foot-tall (8-meter-by-26-meter) space simulator – a place where Surveyor, Voyager, and Cassini got their first taste of space-like environments. For three weeks in September, a team monitored sensors, meters, and cameras as the blades endured run after run at ever-higher speeds and greater pitch angles.
A dual rotor system for the next generation of Mars helicopters is tested in the 25-Foot Space Simulator at NASA’s Jet Propulsion Laboratory on Sept.15. Longer and stronger than those used on the Ingenuity Mars Helicopter, the carbon-fiber blades reached near-supersonic speeds during testing. NASA/JPL-Caltech “We spun our blades up to 3,500 rpm, which is 750 revolutions per minute faster than the Ingenuity blades have gone,” said Tyler Del Sesto, Sample Recovery Helicopter deputy test conductor at JPL. “These more efficient blades are now more than a hypothetical exercise. They are ready to fly.”
At around the same time, and about 100 million miles (161 million kilometers) away, Ingenuity was being commanded to try things the Mars Helicopter team never imagined they would get to do.
Fourth Rock Flight Testing
Ingenuity was originally slated to fly no more than five times. With its first flight entering the mission logbook more than two-and-a-half years ago, the helicopter has exceeded its planned 30-day mission by 32 times and has flown 66 times. Every time Ingenuity goes airborne, it covers new ground, offering a perspective no previous planetary mission could achieve. But lately, Team Ingenuity has been taking their solar-powered rotorcraft out for a spin like never before.
“Over the past nine months, we have doubled our max airspeed and altitude, increased our rate of vertical and horizontal acceleration, and even learned to land slower,” said Travis Brown, Ingenuity’s chief engineer at JPL. “The envelope expansion provides invaluable data that can be used by mission designers for future Mars helicopters.”
Limited by available energy and motor-temperature considerations, Ingenuity flights usually last around two to three minutes. Although the helicopter can cover more ground in a single flight by flying faster, flying too fast can confuse the onboard navigation system. The system uses a camera that recognizes rocks and other surface features as they move through its field of view. If those features whiz by too fast, the system can lose its way.
So, to achieve a higher maximum ground speed, the team sends commands for Ingenuity to fly at higher altitudes (instructions are sent to the helicopter before each flight), which keeps features in view longer. Flight 61 established a new altitude record of 78.7 feet (24 meters) as it checked out Martian wind patterns. With Flight 62 Ingenuity set a speed record of 22.3 mph (10 meters per second) – and scouted a location for the Perseverance rover’s science team.
The team has also been experimenting with Ingenuity’s landing speed. The helicopter was designed to contact the surface at a relatively brisk 2.2 mph (1 mps) so its onboard sensors could easily confirm touchdown and shut down the rotors before it could bounce back into the air. A helicopter that lands more slowly could be designed with lighter landing gear. So, on Flights 57, 58, and 59 they gave it a whirl, demonstrating Ingenuity could land at speeds 25% slower than the helicopter was originally designed to land at.
All this Martian Chuck Yeager-ing is not over. In December, after solar conjunction, Ingenuity is expected to perform two high-speed flights during which it will execute a special set of pitch-and-roll angles designed to measure its performance.
“The data will be extremely useful in fine-tuning our aero-mechanical models of how rotorcraft behave on Mars,” said Brown. “On Earth, such testing is usually performed in the first few flights. But that’s not where we’re flying. You have to be a little more careful when you’re operating that far away from the nearest repair shop, because you don’t get any do-overs.”
More About Ingenuity
Ingenuity began its life at Mars as a technology demonstration. It first flew on April 19, 2021, hovering 10 feet (3 meters) for 30 seconds. Four more flights in as many weeks added 499 seconds and saw the helicopter flying horizontally over the surface for 1,171 feet (357 meters). After proving flight was possible on Mars, Ingenuity entered an operations demonstration phase in May 2021 to show how aerial scouting could benefit future exploration of Mars and other worlds.
The Ingenuity Mars Helicopter was built by JPL, which also manages the project for NASA Headquarters. It is supported by NASA’s Science Mission Directorate. NASA’s Ames Research Center in California’s Silicon Valley and NASA’s Langley Research Center in Hampton, Virginia, provided significant flight performance analysis and technical assistance during Ingenuity’s development. AeroVironment Inc., Qualcomm, and SolAero also provided design assistance and major vehicle components. Lockheed Space designed and manufactured the Mars Helicopter Delivery System.
At NASA Headquarters, Dave Lavery is the program executive for the Ingenuity Mars Helicopter.

A fascinating and unique structure spanning 4 kilometers in length has been discovered on Mars by Myytinkertojat Media and shared by Suspicious0bservers.
While conventional geological perspectives might attribute it to a natural formation, such as a ridge or mountain shaped by specific erosion patterns over the planet's history, this particular structure stands out. Unlike numerous other straight and vertical formations on Mars, it defies the natural order and it does not fit with the surrounding landscape.
Rather than mirroring the typical traits of natural features, this structure bears a striking resemblance to a constructed wall. Notably, even there is a reflection of light bouncing off the structure onto the Martian surface.
This discovery adds to a growing list of anomalies on Mars that defy conventional explanations. Could it be conceivable that this intriguing structure represents the remnants of an ancient wall, perhaps constructed by intelligent beings who once inhabited Mars before a catastrophic event made the planet uninhabitable?
