Mars presents mysteries of cosmic proportions. The question of whether life ever existed on its surface remains unanswered despite decades of robotic investigation. The planet's ancient river valleys suggest liquid water once flowed freely, yet its current frozen desolation offers few clues about this dramatic transformation. The Martian methane mystery - periodic detection of this gas potentially indicating biological processes - tantalises astrobiologists worldwide.

The planet's two moons, Phobos and Deimos, exhibit orbital characteristics suggesting they may be captured asteroids, though their origin story remains disputed. Mars conceals billions of years of geological and potentially biological history beneath its rust-coloured regolith.

Mars has demonstrated extraordinary durability, maintaining structural integrity for approximately 4.5 billion years without significant deterioration. The planet has survived countless asteroid impacts, solar flares, and the complete loss of its magnetic field, yet continues to orbit reliably. Its surface features, including Olympus Mons - the largest volcano in the solar system - have persisted for hundreds of millions of years.

The Martian atmosphere, whilst thin, has protected the surface from the worst of cosmic radiation. Rock samples analysed by rovers suggest the planet will continue existing for several billion years hence, assuming no catastrophic cosmic events intervene.

Mars presents considerable accessibility challenges. Located between 54.6 million and 401 million kilometres from Earth depending on orbital positions, the Red Planet requires a minimum seven-month journey using current propulsion technology. No commercial flights operate this route, and the return policy is, at present, non-existent. The estimated cost of a single human mission exceeds 100 billion dollars, placing Mars somewhat beyond the reach of most household budgets.

Even robotic visitors face a 40% failure rate, with numerous spacecraft having perished attempting the journey. The planet's thin atmosphere offers minimal assistance with braking manoeuvres, leading to what engineers diplomatically term 'lithobraking' - the technical term for crashing.

Mars has captured human imagination since ancient Babylonian astronomers first tracked its distinctive red wandering across the night sky. The planet has inspired countless works of literature, from H.G. Wells' The War of the Worlds to contemporary science fiction. Its name derives from the Roman god of war, lending martial associations that persist in popular culture.

The prospect of Martian colonisation drives billion-dollar space programmes and has influenced educational trajectories for generations of scientists and engineers. Mars serves as humanity's symbol of cosmic ambition, representing the next frontier of species expansion.

Mars maintains an essentially neutral environmental impact on Earth, existing at such distance that its gravitational and electromagnetic influences prove negligible for most practical purposes. The planet neither consumes terrestrial resources nor contributes to atmospheric pollution. Its orbital mechanics do contribute to long-term climate cycles through gravitational resonance effects, though these operate on geological rather than human timescales.

Future Martian colonisation would require significant resource investment, potentially including environmental modifications through proposed terraforming schemes. Such interventions remain speculative but could theoretically transform the planet's atmosphere over centuries of deliberate engineering.
