NASA's approach to Mars rover design exemplifies a blend of cutting-edge technology and rigorous engineering principles tailored to the harsh Martian environment. Each rover, from Sojourner to the more recent Perseverance, is built to perform complex scientific tasks while enduring extreme conditions. The designs incorporate robust mobility systems to navigate diverse terrains, from rocky landscapes to sand dunes. Rovers are equipped with sophisticated scientific instruments intended for astrobiology, geology, and atmospheric studies, helping to unravel Mars' history and assess its habitability. Solar panels or radioisotope thermoelectric generators typically power these rovers, ensuring sustained operations. Additionally, communication systems are crucial for transmitting vast amounts of data back to Earth. With each mission, NASA iteratively improves its rover designs, incorporating lessons learned from previous missions to enhance durability, efficiency, and scientific capabilities.

Perseverance is a complex machine comprising thousands of different parts. Perseverance is built with multiple systems that include cameras, sensors, scientific instruments, and a robotic arm. Each of these systems is made up of numerous components. Although a specific count of every individual part isn't typically detailed publicly due to the complexity and proprietary nature of the design, it's safe to say that the rover includes several thousand distinct parts. These range from small screws and electronic components to large assemblies such as the rover's chassis and wheels.

Alex: "I'm very surprised that all of the rovers on Mars aren't standardized and easy to disassemble for reuse. I think that the unique design of each Martian rover seems inefficient as designed by humans who practice standardization on Earth."

Designing a rover capable of salvaging previous rovers is notably more expensive than creating a standard rover. The increased cost stems from the complexity of the technology, requiring advanced robotics, sensors, and specialized tools. Extensive research and development efforts, including customization for specific missions and target rovers, contribute to the higher expenses. Rigorous testing, integration, redundancy, and potential human involvement further elevate the overall cost.

Despite the greater upfront investment, the benefits of resource recovery and sustainability in future missions may justify these expenses. Salvage rovers have the potential to recycle valuable materials and components, reducing the need for new resources and minimizing waste. The decision to develop a salvage-capable rover should be carefully weighed against the associated costs and mission objectives to determine its feasibility and value.

Current property laws for man-made equipment on Mars are primarily governed by the principles of the Outer Space Treaty of 1967, ensuring that ownership remains with the entity that deployed the equipment, while preventing national appropriation of Martian territory. The Moon Agreement of 1979 allows for the ownership of man-made objects (e.g., rovers, landers) to remain with the entity that launched them.

Salvage-capable systems, designed to repurpose parts from previous missions or repair damaged equipment, would be controlled by their respective country's space agency through a combination of automation and direct remote operations. These space agencies, such as NASA or ESA, would retain jurisdiction and control over their rovers as per the Outer Space Treaty, ensuring compliance with international space law. The control systems would involve a sophisticated blend of pre-programmed instructions and real-time adjustments, facilitated by deep-space communication networks. This setup would enable the systems to efficiently navigate the Martian terrain, identify salvageable materials, and perform intricate repair tasks while adhering to the safety protocols and mission objectives set by their space agency. Continuous supervision and oversight would be necessary to adapt to the dynamic challenges of the Martian environment, ensuring the systems' operations align with both the technical goals and the broader international guidelines for space exploration.

As human activities outside of Earth increase, there will likely be a push for more detailed laws and agreements addressing property rights, resource utilization, and potential conflicts.

The primary mission of Mars 2020 rover involves meticulously collecting Mars rocks and soil, sealing them in tubes, and depositing them at specific surface locations with precise maps for potential future retrieval. In the rover's abdomen, essential equipment like a rotating drill carousel and 43 sample tubes are managed by a small robotic arm. To prevent Earth contamination, "witness tubes" accompany sample tubes, capturing potential contaminants. These witness tubes are opened on the Martian surface to monitor the environment during sample collection. Once collected, samples are stored within the rover until they are strategically placed at designated "sample cache depots" with precise coordinates, allowing for future retrieval and potential return to Earth, ensuring contamination-free Martian material study.

The dirt sample tubes dropped from the Mars 2020 rover look like lightsabers.

Consider the landing sites of the major Mars rover missions: Sojourner (part of the Mars Pathfinder mission in 1997), Spirit and Opportunity (Mars Exploration Rovers, landed in 2004), and Curiosity (Mars Science Laboratory, landed in 2012).

Here are the approximate landing coordinates for each rover:

• Sojourner (Mars Pathfinder): 19.13°N, 33.22°W (Ares Vallis)
• Spirit (MER-A): 14.5684°S, 175.472636°E (Gusev Crater)
• Opportunity (MER-B): 1.9462°S, 354.4734°E (Meridiani Planum)
• Curiosity (MSL): 4.5895°S, 137.4417°E (Gale Crater)

Using these coordinates, we can calculate the great-circle distances between the rovers. This calculation considers the curvature of Mars, which has an average radius of approximately 3,389.5 km. The great-circle distance is the shortest distance between two points on the surface of a sphere, measured along the surface of the sphere (as opposed to a straight line through the sphere's interior).

• Between Sojourner and Spirit: Approximately 9004 km
• Between Sojourner and Opportunity: Approximately 2036 km
• Between Sojourner and Curiosity: Approximately 9633 km
• Between Spirit and Opportunity: Approximately 9670 km
• Between Spirit and Curiosity: Approximately 2292 km
• Between Opportunity and Curiosity: Approximately 8426 km

These distances highlight the vast areas covered by Mars missions and the logistical challenges involved in planning a rover recovery mission, considering the significant distances between each landing site. ​​

A rover recovery mission on Mars, utilizing a helicopter or a modified SkyCrane, would require meticulous planning and innovative engineering solutions. The mission would commence with the deployment of a highly advanced helicopter, designed for the thin Martian atmosphere, or a modified version of the SkyCrane that successfully delivered the Curiosity and Perseverance rovers. This aerial vehicle would need to be equipped with state-of-the-art navigation systems, robust power sources, and a versatile grappling mechanism capable of securely attaching to and lifting the varied designs of the target rovers. The recovery route would be strategically planned to minimize travel distance while navigating around Martian terrain features such as craters, canyons, and dust storm-prone areas.

The mission's first phase would focus on the closest rovers, starting with the pair of Opportunity and Spirit, given their relatively close proximity compared to others. The aerial vehicle would navigate to the Opportunity rover at Meridiani Planum, secure it, and then proceed to the Gusev Crater to recover Spirit. This phase would test the vehicle's operational capabilities, including its lifting power, endurance, and the efficiency of its grappling mechanism. Subsequent phases would target the more distant rovers, with Sojourner and Curiosity being the next priorities. Special attention would be given to optimizing flight paths to conserve energy, taking advantage of prevailing winds, and ensuring safe landings for rover pick-up and drop-off.

Technological advancements, such as improved battery technology or the utilization of nuclear power sources, would be crucial for the success of this mission. The recovery vehicle would also need to be equipped with autonomous systems for navigation and decision-making, given the communication delay between Earth and Mars. This ambitious mission would not only demonstrate the feasibility of Mars surface asset recovery but also pave the way for future missions involving the recycling of hardware and materials, significantly contributing to the sustainability of long-term exploration efforts on the Red Planet.

Estimating the total cost of a Mars rover recovery mission involving a helicopter or modified SkyCrane is complex and depends on numerous factors including development, manufacturing, testing, and operational aspects. The development of a new aerial vehicle capable of navigating the Martian atmosphere and terrain, equipped with advanced grappling mechanisms and autonomous systems, could easily run into the billions of USD. For context, the Mars Helicopter Ingenuity, a technology demonstrator, cost about $85 million to develop and build, and it is a small, simple rotorcraft compared to what would be needed for a recovery mission.

The modified SkyCrane or helicopter would require significant advancements in propulsion, power, and autonomy technologies. Research, development, and testing of these new systems could increase the mission's cost substantially. Additionally, the cost of launching the mission, which includes the launch vehicle, integration, operations, and mission support, would also be a major component of the total cost. A heavy-lift rocket capable of sending the recovery vehicle to Mars could cost upwards of $150 million to $300 million per launch, depending on the launch provider and the mission's requirements.

Given these considerations, a rough estimate for a Mars rover recovery mission could exceed $1 billion to $3 billion, factoring in the development of the aerial recovery vehicle, launch costs, mission operations, and contingencies. This estimate is speculative and could vary widely based on the mission's final design, the technologies employed, and the extent of the recovery efforts. The mission's unprecedented nature and the technological advancements required would likely place it at the higher end of cost estimates for interplanetary missions.

The total time estimate for a Mars rover recovery mission involves several phases, each with its own set of complexities and time requirements. The initial phase, focusing on research, development, and testing of the aerial recovery vehicle (helicopter or modified SkyCrane), could span several years. Given the advanced technologies and novel systems required, this phase alone might take 5 to 7 years, considering the iterative design, extensive testing, and validation processes needed to ensure the vehicle's capability to perform under Mars' unique conditions.

Following the development phase, the preparation and launch phase would include final vehicle assembly, integration with the launch vehicle, and pre-launch testing. This phase could take an additional 1 to 2 years, depending on the launch window availability and the readiness of the launch infrastructure. The transit from Earth to Mars, aligning with the optimal launch window to minimize travel time and fuel consumption, takes approximately 6 to 9 months, depending on the specific alignment of Earth and Mars.

Once on Mars, the operational phase of the mission, including navigating to and recovering each rover, would depend heavily on the distances between rovers, the recovery vehicle's speed and operational efficiency, and the Martian environmental conditions. This phase could take anywhere from several months to over a year, especially when factoring in the time required for planning each recovery leg, executing the operations, and dealing with potential Martian challenges such as dust storms. In total, from initial development to the completion of recovery operations on Mars, the mission could span approximately 7 to 10 years.

Sending humans to Mars presents a unique set of advantages and challenges compared to deploying humanoids, or robots with human-like features. Humans possess the unparalleled ability to make real-time decisions, adapt to unforeseen circumstances, and bring a level of flexibility to problem-solving that current robotic technology cannot match. This adaptability is especially crucial for nuanced scientific research, where human intuition and the ability to pivot based on new findings can lead to significant discoveries. Moreover, the inspirational impact of human spaceflight cannot be understated; it captures the public imagination and fuels interest in science, technology, engineering, and mathematics (STEM) fields, driving further investment in space exploration.

However, the challenges of sending humans to Mars are substantial. Life support systems to provide oxygen, water, food, and waste management significantly increase the complexity and cost of manned missions. Protecting astronauts from cosmic and solar radiation is another major hurdle, given Mars' lack of a significant magnetic field and thick atmosphere. The psychological and physical health risks associated with long-duration spaceflight, including muscle atrophy and bone density loss, pose additional concerns. Furthermore, human missions are inherently more expensive due to the necessities of life support, return vehicles, and extensive safety measures.

On the other hand, sending humanoids to Mars offers its own set of advantages, primarily in risk reduction. Robots can be sent into hazardous environments without the moral and ethical concerns associated with risking human lives, making them ideal for preliminary exploration tasks. From a cost perspective, although advanced robots are expensive to develop, the absence of life support systems makes robotic missions more budget-friendly in comparison. Robots can also be designed for extended operations, allowing for prolonged scientific studies far beyond what would be feasible for human crews. The development of advanced humanoid robots could further drive technological innovations in robotics, AI, and materials science, with broad applications beyond space exploration.

Yet, humanoids are not without their limitations. Their ability to adapt to unexpected situations is still far behind human capabilities, as they require pre-programmed instructions for most tasks and are prone to malfunctions that require remote troubleshooting. The current state of technology limits robot autonomy, with a reliance on delayed instructions from Earth hindering real-time decision-making. Additionally, robots lack the intuition and creativity that humans bring to exploration and scientific discovery, which can be crucial for making significant breakthroughs.

In conclusion, the choice between sending humans or humanoids to Mars involves a complex trade-off between the adaptability and creativity of humans and the risk reduction and cost-effectiveness of robots. A phased approach, starting with robotic missions to conduct reconnaissance and establish infrastructure, followed by human missions to leverage human cognition and creativity, might offer the most balanced strategy for Mars exploration. This combination could maximize scientific returns while minimizing risks and costs associated with deep space exploration.

Creating a mission plan that involves setting off a nuclear explosion on Mars to modify its environment is purely speculative and raises significant ethical, legal, and scientific concerns. Current international space law, including the Outer Space Treaty, to which many spacefaring nations are signatories, prohibits the deployment of nuclear weapons in space. Moreover, the scientific community continues to debate the feasibility and consequences of such drastic measures for terraforming.

The type of animal capable of surviving on the harsh surface of Mars would need to exhibit extreme resilience to cold, radiation, and the near absence of atmospheric oxygen. Envision a creature somewhat akin to Earth's tardigrades or "water bears," renowned for their ability to endure extreme environments. This Martian species, let's call it the "Ares Microbeast," would likely be very small, possibly microscopic, to minimize its exposure to surface radiation and cold. It could possess a biochemistry that allows it to extract water from the minimal moisture found in the Martian soil and utilize carbon dioxide directly from the atmosphere, similar to how plants perform photosynthesis on Earth.

This animal's cellular structure would be extraordinarily robust, possibly having a unique form of DNA repair system to quickly fix damage caused by cosmic rays and solar radiation, challenges that are prevalent on Mars due to the thin atmosphere. Moreover, its metabolism might operate in a cryptobiotic state—meaning it could effectively shut down during prolonged periods of extreme cold or drought, and then revive itself when conditions become more favorable, much like Earth's resurrection plants. Living near or under the surface, it would likely thrive in Martian caves or crevices, where it can avoid some radiation and perhaps access subsurface ice deposits for water, pointing to a fascinating adaptation strategy in the stark conditions of Mars.

To determine landing spots on Mars for rockets and rovers, NASA and other space agencies consider factors like scientific value, surface safety, accessibility, and potential for future exploration. The primary objective often shapes the choice: for science-focused missions, such as the Mars rovers, regions with significant geological diversity, ancient water flow indicators, or unique mineralogy are prioritized. For example, NASA's Curiosity rover landed in Gale Crater due to the presence of layered sedimentary rocks, which can preserve a record of past environmental conditions, including potential ancient water bodies. Engineers simulate Mars' conditions, conduct risk assessments of terrain features, and rely on high-resolution imagery from orbiters like the Mars Reconnaissance Orbiter (MRO) to meticulously analyze potential sites.

Surface safety is a critical factor. The landing area must be relatively flat and free of large boulders, cliffs, and other hazards that could endanger the spacecraft. For instance, NASA’s Perseverance rover landed in Jezero Crater, a challenging yet scientifically promising site. To handle the crater's rugged terrain, NASA equipped Perseverance with a new "Terrain Relative Navigation" (TRN) system, which allows the rover to navigate hazards autonomously. This site was chosen despite its risks due to signs of an ancient river delta, which is an ideal spot for looking for biosignatures. This navigation system was crucial, as it enabled precise landing amidst potentially treacherous landscapes that would be off-limits to rovers with less sophisticated landing technologies.

Additionally, agencies evaluate accessibility to sunlight and communication capabilities. For example, solar-powered missions, like the Mars Pathfinder, needed sunny landing sites near the Martian equator to maximize energy absorption. In contrast, NASA’s InSight mission landed at Elysium Planitia, a flat plain close to the equator, which was favorable for its stationary scientific instruments. The landing site selection process combines various high-resolution mapping tools, remote sensing technologies, and simulations to ensure the safe deployment of scientific instruments and data relay capabilities between the lander and Earth. This multidisciplinary approach is essential for understanding both the landing environment and the broader implications of site choice on mission success.

For SpaceX's Starship missions to Mars, likely landing sites will consider a balance of surface safety, proximity to essential resources like water ice, and favorable solar conditions for energy production. Based on current research and speculation, locations in the mid-latitudes, like the Arcadia Planitia, are considered promising. Arcadia Planitia has flat plains and evidence of subsurface ice, which could provide a valuable water source for producing oxygen and fuel. Its relatively mild terrain and potential accessibility to resources align with SpaceX’s goal of establishing a sustainable human presence on Mars.
