Mikrometeoroidy

Te moon lacks an atmosfere, and Mars has only a thin one, so both surfaces are subiet to micrometeoroid impacts.

Power Supply andEnergy Management

A reliable power source is thee lifeblod of any autonous vehicle. The choice of power system influences mass, coss, mission duration, and operational limitins.

Solar Power Challenges

Solar panels are te mest power source for surface rovers, but they face significant obstacles on both the Moon andMars. On the lunar surface, thee 14.5 -day- long night mean no solar for half of each month. In polar kraters that are candidates for water ice, permanent shadows block sunlight entirely. On Mars, global dusstorms can blocks up to 99% of sunlight for weeks, rendering sollais usels usels.

Alternatywy Nuclear Power

For misses requiring continuous operation through long night or duss storms, radioizotope power systems (RPS) such as radioizotope terieclectric generators (RTGs) are a proven solution. RTGs convert the heat frem plutonium-238 decay into electricity, providing steady power for decades. The Perseane rover uses a Multi- Mission RTG (MRTG) exering about 110 wats.

Arm andInstrument Deployment

Many ASV carry robotic arms for sample collection, deploying instruments, or clearing debris. The arm mutt be lightweight yet stiff enough to operate in low gravity. Precise strouge control andd torque limits are needed to avoid damaging scientific fores. On Mars, the Sample Handling and Caching System on Perseliance use a turret with multiple tools. Lunar arms for future rovers will need tpe handle extreme cold and dust whille maintaintaing.

Engineers use special geases with a broad temperatur range, such as Braycote, and sometimes contacte heaters into actuator housings. Seals mutt prevent dust duss ingress while allowing motion. Some designs use magnetic couplings or encapsulates motors to avoid contact with regolith.
