1. SpaceX Starship
Payload Capacity
The SpaceX Starship is engineered to deliver up to 100 metric tons (about 220,462 pounds) of payload to the Martian surface in a single flight. To put that into perspective, NASA's Perseverance rover carried just around 1 metric ton to Mars. This massive payload capacity means Starship can transport multiple rovers, habitat modules, and even construction equipment in one trip. It’s equipped with large payload deployment doors, approximately 3 meters by 3 meters (roughly 10 feet by 10 feet), allowing for the autonomous unloading of heavy equipment. Combined with its reusability, this capability makes Starship a game-changer for interplanetary missions.
Reusability Features
Starship is designed for full reusability, featuring a heat shield made with hexagonal metallic-ceramic tiles capable of withstanding repeated atmospheric entries. During descent, it performs a unique "belly-flop" maneuver, using four flaps to guide its descent before flipping upright for a vertical landing powered by its engines. Standing at 52 meters (171 feet) tall, it’s the tallest spacecraft ever designed for landing on Mars. While this height provides exceptional payload space, it also introduces stability challenges that engineers have worked to address. Notably, the first Starship vehicles sent to Mars are planned to remain there permanently, serving as part of the infrastructure for future missions.
Surface Mobility Support
Starship's design also simplifies operations on the Martian surface. Its spacious payload bay can carry multiple mobile platforms and vehicles, such as rovers and rotorcraft, in both the forward and aft cargo areas. This setup allows for direct deployment, enabling simultaneous operations and broader surface exploration. The payload bay also provides direct access to the Martian surface, streamlining the deployment of equipment and allowing crews to exit the spacecraft more efficiently.
Crew Return Capability
One of Starship's standout features is its ability to bring the crew back to Earth. It achieves this by refueling on Mars, using local resources to produce methane and oxygen propellants through a process called in-situ resource utilization (ISRU). Early uncrewed missions will focus on setting up the necessary ISRU infrastructure and scouting for resources. Once refueled, Starship can take off directly from Mars, carrying both crew and cargo back to Earth. This round-trip capability is a game-changer for Mars exploration, paving the way for sustainable crew rotations and the regular return of materials, which are critical for establishing a long-term human presence on the Red Planet.
2. NASA Mars Ascent Vehicle
Payload Capacity
The NASA Mars Ascent Vehicle (MAV) is built with one specific mission in mind: bringing samples back from Mars. It’s designed to carry about 500 grams (approximately 1.1 pounds) of Martian material to orbit. The vehicle itself is relatively compact, measuring 2.8 meters (9.2 feet) in length and 0.57 meters (1.9 feet) in diameter. Despite its small size, it weighs around 400 kilograms (880 pounds) - a stark contrast to the massive 100-metric-ton capacity of SpaceX's Starship. Tailored exclusively for NASA's Mars Sample Return mission, the MAV is set to make history as the first rocket to launch from another planet.
Surface Mobility Support
Unlike the highly adaptable Starship, the MAV is a stationary vehicle. It’s designed to launch from a fixed platform delivered to Mars by a lander. While Starship can deploy cargo and move independently, the MAV focuses solely on one task: ascending to orbit with collected samples. It relies entirely on rovers to gather and deliver those samples to its platform. This specialized design ensures a clear division of responsibilities - rovers handle surface exploration, while the MAV takes on the critical job of transporting the samples into orbit.
Crew Return Capability
The MAV is uncrewed and laser-focused on its ascent mission. To complete its task, it needs to reach speeds of about 4 km/s (approximately 8,950 mph), allowing it to deliver its sample container into Mars orbit. Once in orbit, the container will be captured by a waiting spacecraft for its journey back to Earth. While the current design is solely for sample return, there are concepts for a crewed version in the future. These ideas include adding life support systems, increasing payload capacity, and using in-situ resource utilization (ISRU) to produce propellant on Mars. For now, the MAV’s design emphasizes reliability and efficiency, ensuring it can withstand the harsh Martian environment, including extreme temperature fluctuations and extended periods on the surface.

3. Starboat Concept Design
The Starboat concept introduces a fresh perspective for Mars exploration, prioritizing mobility and modular functionality over sheer cargo capacity.
Payload Capacity
Designed for surface operations on Mars, the Starboat takes advantage of the substantial cargo capacity offered by next-generation landers like Starship. It is proposed to carry between 20 and 50 metric tons - less than Starship's 100-metric-ton capacity. This reduction is intentional, trading off raw payload size to focus on specialized tasks. The Starboat's primary goal is to efficiently transport and reposition critical assets across the Martian surface, ensuring resources are deployed where they’re most needed.
Reusability Features
Unlike the fully reusable Starship, which is designed for Earth-to-Mars missions, the Starboat focuses on partial reusability for operations confined to the Martian surface. It would rely on Mars-refueled propellant to perform multiple surface hops, extending its operational lifespan. Key design features include sturdy landing gear, components resistant to Martian dust, and modular parts that can be serviced or replaced on-site. This approach ensures the Starboat can handle repeated use without requiring a return to Earth, making it a practical tool for sustained exploration.
Surface Mobility Support
One of the standout features of the Starboat is its emphasis on mobility. Equipped with propulsion systems, it could "hop" between locations, covering terrain that traditional rovers cannot navigate. This capability would allow for broader scientific exploration and greater redundancy, as multiple vehicles could be deployed simultaneously. Even if one vehicle faces an issue, others could continue operations. Experts like Robert Zubrin and NASA mission planners have emphasized the importance of such mobility in creating a lasting human presence on Mars.
Crew Return Capability
While the Starboat is not designed for direct Earth return, it offers limited crew return capability to Mars orbit. This means it can transport crew members to orbit, where they would rendezvous with a dedicated return craft. By focusing solely on Mars-orbit ascent, the Starboat avoids the added complexity and mass required for interplanetary travel. This design keeps the vehicle streamlined and better suited for surface operations, while still ensuring crew safety. However, this strategy does depend on additional orbital infrastructure to complete the return journey.
Advantages and Disadvantages
When it comes to sustainable Mars operations, every vehicle design comes with its own set of trade-offs. These trade-offs play a crucial role in determining which vehicle is best suited for specific mission needs.
SpaceX Starship stands out for its sheer capability and affordability. With an impressive payload capacity, it can deliver volumes that traditional methods simply can't match.
