What the Mars Flyby Missions Captured — and Why It Matters
Flyby mission captures historic views of Mars — and in 2025 and 2026, two spacecraft did exactly that, delivering some of the most striking images of the Red Planet in years.
Here’s a quick summary of what happened:
- NASA’s Psyche spacecraft flew within 2,864 miles (4,609 km) of Mars on May 15, 2026, capturing crescent views, the south polar cap, and sweeping canyon systems
- ESA’s Hera spacecraft passed within 5,000 km of Mars and just 300 km from its moon Deimos on March 12, 2025, snapping the first-ever spectral image of Deimos’s far side
- Both flybys served as gravity assists — using Mars’s gravitational pull to boost speed and adjust trajectory without burning extra fuel
- Psyche gained a 1,000 mph speed boost and is now on course to reach asteroid 16 Psyche in 2029
These weren’t just pretty pictures. Each flyby was a carefully planned scientific event — testing instruments, confirming trajectories, and revealing new details about Mars and its moons.

Flyby Mission Captures Historic Views of Mars: The Psyche Encounter
On May 15, 2026, the NASA Psyche spacecraft executed a flawless maneuver that brought it closer to the Red Planet than most of us will ever get to a festival stage. Passing just 2,864 miles (4,609 kilometers) above the Martian surface, the spacecraft utilized the planet’s massive gravitational pull as a natural slingshot.
This wasn’t just a casual drive-by. By dipping into Mars’s gravity well, the spacecraft received a 1,000 mile-per-hour boost to its velocity. It also achieved a critical 1-degree shift in its orbital plane relative to the Sun. This “gravity assist” is essential for long-distance space travel; it’s like catching a perfect gust of wind that carries you toward your destination without having to pedal. For Psyche, that destination is a 2.2 billion-mile journey to a metal-rich asteroid.
During this high-speed encounter, the mission team took the opportunity to point their cameras toward the planet. The result was a series of images that NASA’s Psyche captures gorgeous Mars crescent photo on way to asteroid, showing the planet from a perspective we rarely see from Earth-bound telescopes or even orbiting satellites.
Historic Views of Mars Captured by Psyche’s Multispectral Imager
The images returned by the Psyche mission are nothing short of breathtaking. Because of the specific angle of the flyby, the spacecraft captured Mars as a glowing, thin crescent. This perspective is particularly valuable because it highlights the Martian atmosphere. The dusty air scatters sunlight, making the illuminated edge of the planet appear exceptionally bright and causing the crescent to stretch further around the planet’s circumference than it would on a world without an atmosphere.
As the spacecraft moved past its closest approach, it captured a nearly “full” view of the planet. These photos showcased iconic Martian landmarks, including:
- Huygens Crater: A massive impact basin measuring roughly 470 kilometers (290 miles) in diameter. Enhanced color views helped scientists distinguish between the bedrock, sand, and dust within the crater.
- Valles Marineris: The “Grand Canyon of Mars,” a sprawling system of canyons that dwarfs anything we have on Earth.
- Syrtis Major: A dark volcanic region where the spacecraft’s high-resolution sensors picked up wind-blown streaks stretching nearly 50 kilometers (30 miles) across the surface.
- The South Polar Cap: Psyche provided a stunning look at the 700-kilometer-long frozen expanse of the southern pole.
According to Psyche Mission Captures Never-Before-Seen Images of Mars During Flyby, the ability to capture these high-speed shots at nearly 20,000 km/h without motion blur is a testament to the advanced imaging technology on board.
Scientific Calibration During the Flyby Mission Captures Historic Views of Mars
While we all love a good space photo, the primary reason for turning the cameras on was scientific calibration. Before the spacecraft reaches its final target—the asteroid 16 Psyche—the team needs to ensure every instrument is working perfectly.
The Mars flyby served as a “dress rehearsal.” By imaging a known target like Mars, engineers could test the multispectral imagers, the gamma-ray and neutron spectrometer, and the magnetometer. It was also a chance to test communication with the Deep Space Network, ensuring that when the craft reaches the asteroid belt in 2029, it can send its data back home without a hitch.
This calibration process is a vital part of the Trajectory Tweaked Mars Gravity Propels Psyche Toward Asteroid Belt strategy. By using Mars as a test subject, the team verified that their image processing tools were ready to handle the unique lighting conditions of deep space.
Beyond the Red Planet: ESA’s Hera and the Deimos Flyby
While Psyche was making headlines in 2026, the European Space Agency’s (ESA) Hera mission had its own historic moment just a year prior. On March 12, 2025, Hera performed its own Mars flyby, coming within 5,000 km of the planet.
However, Hera had a secondary target: Deimos, the smaller and more distant of Mars’s two moons. Hera zoomed within a mere 300 km of Deimos, providing an unprecedented look at this tiny, lumpy world. Deimos has traditionally been difficult to study because it is usually imaged from the Martian surface or from high orbits. Hera’s close approach allowed for the first-ever spectral image of the far side of Deimos.
Using an innovative Dutch instrument called the HyperScout H, the mission captured hyperspectral data that reveals the chemical composition of the moon’s surface. This is a huge win for planetary defense and our understanding of how these moons formed. As noted in the report on Amazing new images of Mars captured by a spacecraft zooming past on its way to the asteroid belt, this data helps determine if Deimos is a captured asteroid or a piece of Mars itself that was blasted into space long ago.
The Science of the Slingshot: Gravity Assists and Calibration
Why do we send spacecraft on these “scenic routes” instead of flying in a straight line? It all comes down to orbital mechanics and fuel. Space is big—really big—and carrying enough fuel to reach the outer solar system is incredibly heavy and expensive.
A gravity assist (or slingshot) allows a spacecraft to steal a tiny bit of a planet’s orbital energy. This changes the spacecraft’s velocity and direction for “free.”
| Statistic | Psyche (May 2026) | Hera (March 2025) |
|---|---|---|
| Closest Mars Approach | 4,609 km (2,864 miles) | 5,000 km |
| Velocity Boost | 1,000 mph | N/A (Trajectory focus) |
| Primary Goal | Reach Asteroid 16 Psyche | Reach Asteroid Dimorphos |
| Unique Feature | High-angle crescent views | Deimos far-side spectral data |
These maneuvers are also the perfect time for a “check-up.” Just as the Nasa Perseverance Rover Captures New Selfie On Mars helps engineers monitor the rover’s health on the surface, these flyby images tell the teams in mission control that their “eyes in the sky” are focused and ready for the main event.
Comparing Modern Flybys to the History of Mars Exploration
When we look at the images from 2025 and 2026, it’s easy to forget how far we’ve come. The very first successful flyby mission captures historic views of Mars was NASA’s Mariner 4 in July 1965. Back then, the images were grainy, black-and-white, and took hours to transmit.
Historically, Mars has been a tough nut to crack. Roughly 60% of all missions destined for the Red Planet have ended in failure. From the early Soviet attempts to the Viking program of the 1970s, every success has been hard-won. Today, we have high-resolution sensors that can pick out wind streaks and individual craters from thousands of miles away, a feat that would have seemed like science fiction to the Mariner 4 team. You can find a deeper dive into this history at Everything You Ever Wanted To Know About Science.
Future Milestones After the Flyby Mission Captures Historic Views of Mars
So, where are these spacecraft headed now?
For Psyche, the journey is far from over. After its 2026 Mars encounter, it is cruising toward the main asteroid belt. It is scheduled to arrive at asteroid 16 Psyche in August 2029. This asteroid is unique because it is thought to be the exposed metallic core of a “planetesimal”—a building block of an early planet that had its outer layers stripped away by violent collisions billions of years ago. By studying it, we are essentially looking at the “heart” of a planet like Earth.
Hera is also on a mission of discovery. After leaving Mars, it is heading toward the binary asteroid system of Didymos and Dimorphos. It will arrive in late 2026 to perform a “crime scene investigation” of NASA’s DART mission, which intentionally crashed into Dimorphos to see if we could deflect an asteroid’s path.
According to NASA’s Psyche Mission Sees Mars’ South Pole After Flyby, these missions are providing the data we need to understand the very formation of our solar system.
