When NASA’s Perseverance rover touched down in Jezero Crater on February 18, 2021, it wasn’t just another chapter in the exploration of Mars (Mars, scientific designation: Mars / Ares). It was a turning point—an inflection moment in humanity’s long, red-dust-covered pursuit of one profound goal: determining whether life ever emerged on another world. Perseverance was built to drill into ancient lakebed sediments, collect meticulously sealed core samples, test technology for future human missions, and scout environments that could one day support astronauts. But even as the rover continues to trundle across the crater’s rugged landscape, NASA and its international partners are preparing for what comes next. A new wave of Mars exploration is rising—more ambitious, more technologically advanced, and far more interconnected than any era before. These upcoming missions aim to answer the highest-order scientific questions, advance the engineering required for humans to set foot on Mars, and prepare for a future where robots and astronauts may work side by side. From the highly anticipated Mars Sample Return campaign to next-generation orbiters, long-distance helicopter scouts, and preparations for crewed exploration, the post-Perseverance future is shaping up to be NASA’s most daring chapter on the Red Planet yet.
A New Era Begins: The Legacy of Perseverance
Perseverance didn’t land on Mars in a vacuum. It inherited two decades of experience from Spirit, Opportunity, and Curiosity—rovers that revealed Mars’s watery past, its ancient river deltas, and the chemical fingerprints of habitability. But Perseverance’s mission is fundamentally different: it is the first step in a planetary-scale relay race. Rather than analyzing everything on Mars itself, it collects and caches samples for return to Earth, where laboratories can perform deep, sophisticated analysis beyond the capability of any robotic payload.
By drilling into the sediments of an ancient lakebed and its surrounding environment, Perseverance has been able to capture both igneous rocks that tell the story of Mars’s volcanic crust and sedimentary rocks that preserve a snapshot of ancient water flow. Together, these samples offer clues about Mars’s climate cycles, its early atmosphere, and whether the conditions existed for microbial life to take root. But NASA always knew that Perseverance could only be the beginning. The next steps—retrieving those samples, launching them off the planet, and delivering them safely back to Earth—represent some of the most challenging engineering NASA has ever attempted.
As Perseverance continues to explore, planetary scientists, mission planners, and aerospace engineers are working behind the scenes on the next chapter of exploration—one that expands the scope of Mars missions far beyond anything currently rolling across Jezero Crater.
Mars Sample Return: The Most Ambitious Planetary Mission in History
NASA’s Mars Sample Return (MSR) program is widely considered the most complex and scientifically valuable robotic exploration endeavor ever attempted. The campaign’s purpose is straightforward: retrieve the rock cores Perseverance has collected and bring them to Earth. Its execution, however, requires multiple spacecraft, a coordinated interplanetary ballet, and technologies that have never been used before on another planet.
MSR includes three major components. First, a Sample Retrieval Lander will touch down near Perseverance, bringing with it the critical Mars Ascent Vehicle—a small rocket designed to launch the sealed sample tubes into Mars orbit. Second, the system requires a method to collect the tubes and place them inside the ascent rocket. Current plans anticipate that Perseverance itself will deliver most of the samples directly to the lander, but NASA has also considered backup elements, including autonomous drones or small fetch rovers capable of retrieving any cached tubes if needed.
The ascent rocket represents the most unprecedented step of all. No spacecraft has ever launched from the surface of another planet. If successful, the Mars Ascent Vehicle will propel a container known as the Orbiting Sample capsule into orbit, where a third spacecraft—an Earth Return Orbiter built with international partners—will capture it. This orbiter will then ferry the samples back to Earth in a protective Earth Entry System designed to survive atmospheric reentry and deliver the samples safely to a secure receiving facility.
Scientists expect that once the tubes reach Earth, laboratories will begin years of analyses with microscopes, spectrometers, chemical assays, and imaging tools far more sensitive than any rover instrument could carry. This work may help determine whether microbial life left behind biosignatures in Mars’s ancient sediments, whether volcanic processes shaped the planet’s crust differently from Earth, and how water chemistry evolved across billions of years. For many researchers, Mars Sample Return is the holy grail—the long-awaited moment when Mars becomes not just a destination for exploration, but a source of physical material for deep planetary science.
The Next Generation of Mars Orbiters
While Perseverance works on the ground, future missions must rely on orbiters to map terrain, search for landing sites, and relay communications between Earth and surface operations. Several next-generation orbiters are currently in conceptual or planning stages, each designed to push the boundaries of what Mars exploration can accomplish.
NASA and its partners envision orbiters with ultra-high-resolution imaging systems capable of resolving features just tens of centimeters across—sharp enough to monitor dust storms, track surface changes, and scout safe traverses for future rovers and planes. These orbiters will also help plan the first human landing sites by identifying ice deposits beneath the surface. Subsurface water ice is critical for crewed missions, as it can support drinking water, radiation shielding, fuel production, and even agriculture.
Some mission concepts propose synthetic aperture radar systems capable of mapping the Martian crust at depth, revealing the structure of buried canyons, ancient lakes, and volcanic flows. Others focus on climate science, with instruments designed to track dust storms, temperature fluctuations, and seasonal carbon dioxide cycles.
These orbiters will also play a crucial role in communication. As human missions draw closer, NASA will require high-bandwidth relay networks to transmit video, scientific data, and real-time telemetry. Developing this “Mars internet” begins now, long before the first astronauts arrive.
Mars Helicopters: From Ingenuity to Entire Fleets
One of the most surprising breakthroughs to emerge from the Perseverance mission is the success of the Ingenuity helicopter. Originally designed as a technology demonstration, Ingenuity proved that powered flight is possible in Mars’s thin atmosphere—a feat once thought nearly impossible. What followed was an unexpected second act: Ingenuity performed dozens of reconnaissance flights, scouting terrain and providing aerial images that helped Perseverance navigate treacherous paths.
NASA is now designing the next generation of Mars rotorcraft. Unlike Ingenuity, which weighed just under four pounds, future helicopters could be substantially larger, capable of lifting scientific instruments, collecting samples, or transporting small payloads across long distances. These drones could explore rugged terrain inaccessible to wheels, such as cliffs, canyon walls, lava tubes, and steep dunes.
Future missions may incorporate multiple helicopters working in coordinated fleets. Imagine an airborne network of scouts mapping terrain, analyzing rock formations, or retrieving caches from remote regions. These rotorcraft could dramatically extend the reach of surface missions, enabling exploration of scientifically rich areas previously unreachable by rover.
NASA has also considered using helicopters as secondary sample-retrieval vehicles in the Mars Sample Return campaign. These drones would fly out, pick up sealed tubes deposited across the landscape, and return them to a lander—eliminating many of the risks associated with sending a small rover across tough terrain. Whether in support roles or as standalone explorers, Mars rotorcraft are poised to become key players in the next era of robotic discovery.
Building Toward Humans on Mars
Even as robotic exploration grows more advanced, NASA has never lost sight of its long-term goal: sending astronauts to Mars. The agency’s Artemis program, which focuses on lunar exploration, is designed as a proving ground for technologies that will be essential on the Red Planet. The Moon serves not as a detour but as a training lab for deep-space operations—including radiation protection, life-support systems, surface mobility, and in-situ resource utilization.
Future Mars missions will require a wide array of innovations. New propulsion systems, such as nuclear thermal propulsion, could shorten the journey between Earth and Mars, reducing astronauts’ exposure to cosmic radiation. Advanced life-support systems must operate autonomously for months or years at a time. Habitats must be capable of shielding crews from dust storms, temperature extremes, and high-energy radiation.
One of the most critical challenges is resource utilization. Carrying all necessary supplies from Earth is impractical, so astronauts will need to produce water, fuel, and oxygen locally. Perseverance began testing this process with MOXIE, a small experimental unit that successfully extracted oxygen from the Martian atmosphere. Scaling this technology is essential for supporting future crewed missions.
Scientists and engineers also study landing technology. Mars’s thin atmosphere makes descent extremely difficult. Parachutes alone are insufficient for slowing large payloads, so NASA is researching supersonic retropropulsion—firing engines while descending through the atmosphere—for future human landers.
Finally, astronauts must have mobility and scientific capability once they arrive. Pressurized rovers, robotic assistants, aerial drones, and modular habitats will all form part of a future Mars ecosystem. Surface operations may involve exploring ancient riverbeds, drilling deep into crustal layers, and searching for subsurface ice deposits. The goal is to create a sustainable presence on Mars, not a brief visit.
Science Priorities After Perseverance
With Perseverance paving the way, NASA’s scientific priorities for Mars over the next few decades are becoming clearer. One major focus is understanding the planet’s climate history—how it transitioned from a warm, wet world with flowing rivers into the cold, arid planet we see today. Studying ancient sediments, atmosphere chemistry, and volcanic activity can help answer these questions and provide insight into planetary climate evolution across the solar system.
Astrobiology remains at the heart of NASA’s mission strategy. Mars is the best nearby target for studying the potential origins of life beyond Earth. Ancient lakebeds, hydrothermal deposits, and subsurface environments represent the best places to search. Sample return missions will allow scientists to examine minerals and molecules with precision tools, potentially identifying biosignatures or chemical patterns associated with life.
Another priority is understanding Mars’s interior. Future landers may deploy seismometers, heat-flow probes, and magnetometers to map the structure of the crust, mantle, and core. These missions build on the successes of NASA’s InSight lander, which recorded thousands of marsquakes. Understanding Mars’s internal structure can help scientists determine how planets differentiate, cool, and evolve.
Atmospheric studies also remain important. Dust storms can grow to planetary scale, blocking sunlight and affecting temperature patterns. Understanding these storms is essential for protecting future robotic and human missions. New orbiters with advanced atmospheric sensors will help scientists track the development, behavior, and long-term cycles of Martian dust.
International Partnerships in Mars Exploration
While NASA leads many Mars missions, the future of exploration is global. The European Space Agency (ESA) is a key partner in Mars Sample Return, contributing major components such as the Earth Return Orbiter and sample-handling systems. ESA’s ExoMars Rosalind Franklin rover, though delayed, represents another attempt to drill below the surface—one of the best places to search for preserved organic molecules.
Other space agencies are making significant contributions as well. The United Arab Emirates’ Hope spacecraft, currently orbiting Mars, provides atmospheric data that complements NASA missions. China’s Tianwen-1 mission, which includes an orbiter, lander, and rover, has already achieved significant milestones and signals long-term plans for future Mars exploration. India, Japan, and several private U.S. companies are also exploring potential missions, instruments, or support roles.
These collaborations help share cost, expertise, and technology across nations. They also foster scientific cooperation, ensuring that discoveries on Mars benefit humanity as a whole. As exploration grows more complex, these partnerships will be essential for building sustainable and diverse scientific teams capable of tackling the immense challenges ahead.
The Road to a Sustainable Martian Future
Sustainable exploration means more than planting flags or operating isolated missions. It involves planning for a long-term presence that advances science, supports human activity, and maintains planetary protection standards. This includes ensuring that Earth microbes do not contaminate Martian environments and that Mars materials do not pose risks upon return. NASA works closely with organizations such as COSPAR to maintain strict safety protocols during all phases of mission planning.
Sustainability also involves designing missions that build on one another. Data from Perseverance will inform landing site selection for future missions. Weather measurements will support the development of safe descent systems for crewed vehicles. Mapping ice deposits will guide resource-production strategies. Each mission contributes part of a growing knowledge network, creating a blueprint for future explorers.
Long-term sustainability also requires autonomy. Robotics and artificial intelligence will increasingly handle maintenance, construction, repairs, and scientific analysis in the harsh Martian environment. Future missions may include robotic “caretakers” that repair equipment between crew visits, maximizing the lifespan of habitats and vehicles.
Ultimately, sustainability is about continuity—ensuring that exploration does not stall between mission cycles but instead evolves toward increasingly ambitious goals.
Mars in the 2040s and Beyond
Looking a few decades ahead, NASA envisions a Mars exploration program that includes both continuous robotic presence and periodic human crews. By the 2040s or 2050s, astronauts may live and work on Mars for months at a time, conducting ambitious scientific studies and testing technologies for possible future missions deeper into the solar system.
Robotic scouts may venture into caves and lava tubes, searching for protected environments where biosignatures could persist. Large-scale drilling rigs may extract samples from kilometers below the surface. Scientists may use 3D printing technologies to construct shelters, tools, or replacement parts from Martian regolith. Future helicopters may carry full scientific payloads capable of flying tens of kilometers per day, radically accelerating surface exploration.
Communication networks will become more seamless. High-bandwidth systems could allow near real-time communication between astronauts and mission control. Eventually, Mars may host infrastructure similar to what we have in Earth orbit—satellites, weather monitoring systems, relay networks, and science platforms. All of this will rely on the foundational missions being planned and built today.
The Moment We Stand On the Threshold of Discovery
Perseverance is still drilling, imaging, analyzing, and transmitting data from Jezero Crater, but its role in Mars exploration is already evolving. It has become a bridge between NASA’s past accomplishments and its future ambitions. What comes next after Perseverance is not just another mission; it is an interplanetary strategy—an integrated, multi-decade vision for understanding a world that has fascinated humanity for centuries.
The rover’s samples could rewrite the story of life in our solar system. New orbiters will help us see Mars with unprecedented clarity. Next-generation helicopters will soar above canyons and cliffs that no rover could reach. And for the first time in history, humanity is preparing to send astronauts to explore another planet.
NASA’s mission to Mars is entering its most exciting era yet. The coming years promise breakthroughs that will expand our knowledge, redefine our technological boundaries, and bring us closer than ever to answering one of the oldest questions in science: Are we alone?
The story of Mars is far from complete—Perseverance was only the beginning. The next chapters will be written not just by rovers or robots, but by a global partnership of nations, scientists, engineers, and eventually, by human beings who will stand on the Red Planet themselves. The journey continues, and the future of Mars exploration has never been brighter.
