In "And Now For Something Completely Different" by Jodi Taylor the team from St Mary's travel to Mars. In this history briefing, we explore the mystery of lost Martian spacecraft.
Mars, the enigmatic Red Planet, has captivated the imagination of scientists, astronomers, and the public for centuries. As our closest planetary neighbour in the solar system with the highest potential for past or present life beyond Earth, Mars has become the target of numerous space missions since the dawn of space exploration. Yet, despite humanity’s technological advancements, a perplexing pattern has emerged: an unusual number of missions to Mars have ended in failure, with spacecraft mysteriously going silent or disappearing entirely. This curious phenomenon has become widely known as "The Mars Effect". This is not a scientific designation but rather a phrase coined to describe the strange frequency with which space missions to Mars encounter difficulties. It has haunted both robotic explorers and satellites, raising eyebrows and sparking speculation among the scientific community and the general public alike. Historically, Mars missions have suffered a disproportionately high failure rate compared to missions to other celestial bodies, such as the Moon or Venus. The failures have been documented since the early days of Mars exploration, beginning with the USSR’s Marsnik 1 in 1960, which failed to leave Earth’s orbit.
In the decades since, a series of high-profile mishaps have compounded the mystery. NASA’s Mars Observer disappeared without a trace in 1993, just days before it was set to enter Martian orbit. The UK’s Beagle 2 lander was declared lost in 2003 after failing to make contact with Earth. Even sophisticated missions like the European Space Agency’s Schiaparelli lander suffered failures, highlighting the challenges and dangers of interplanetary exploration.
Despite the tantalising suggestion of a “curse,” the reality of The Mars Effect is rooted in the harshness and complexity of space travel. Scientists and engineers have offered several plausible explanations for why so many missions go awry when venturing to Mars.
1. Distance and Communication Challenges
Mars is a considerable distance from Earth, averaging about 225 million kilometres away. This distance creates a significant communication delay, with signals taking between 5 and 20 minutes to travel one way. The vast distance also means that any anomaly or malfunction must often be addressed autonomously by the spacecraft, as real-time human intervention is not feasible. The need for flawless onboard software and automated responses leaves little room for error.
2. Atmospheric and Environmental Hazards
Mars’ thin and unpredictable atmosphere poses a formidable challenge for spacecraft entering its orbit or attempting a landing. Unlike Earth, where the atmosphere provides a relatively smooth deceleration for incoming spacecraft, Mars’ atmosphere is dense enough to cause complications but too thin to effectively slow down an object without additional assistance. Spacecraft need heat shields, parachutes, and retro-rockets in perfect synchrony to land safely. A slight miscalculation can result in catastrophe, as was the case with the Schiaparelli lander, which misjudged its altitude and crashed.
Furthermore, Mars’ surface and weather conditions are extremely harsh. Dust storms, which can cover the entire planet for weeks, are notorious for damaging equipment and blocking solar panels. The Martian dust, composed of fine, abrasive particles, can also degrade mechanical components over time.
3. Human Error and Engineering Limitations
Despite humanity’s best efforts, human error has been a recurring culprit in Mars mission failures. One infamous example is the Mars Climate Orbiter, which was lost in 1999 because of a simple but critical mistake: engineers at Lockheed Martin used imperial units, while NASA’s team used metric units. The discrepancy led to a navigation error, causing the spacecraft to disintegrate in Mars’ atmosphere. Such mishaps underline the complexity of designing and operating interplanetary missions, where even minor oversights can have devastating consequences.
While The Mars Effect has been a persistent theme in space exploration, advancements in technology have begun to turn the tide. More recent missions, such as NASA’s Perseverance rover and the UAE’s Hope Probe, have successfully reached Mars, collecting valuable data and demonstrating that lessons have been learned from past failures. Sophisticated onboard systems, improved communication protocols, and more rigorous testing procedures have contributed to higher success rates in recent years.
Moreover, international collaboration has brought new expertise and resources to the table. As more nations invest in space exploration, the knowledge base for tackling the Red Planet’s challenges has expanded, increasing the likelihood of future successes.
Despite the obstacles, Mars remains a tantalising target. The potential discovery of life, either past or present, drives scientists to overcome the many challenges. Future missions are set to be even more ambitious, with plans for sample return missions and, eventually, human exploration. Each mission will carry the weight of those that came before, equipped with the latest technologies and lessons from the past.
In the end, The Mars Effect serves as a reminder of the unforgiving nature of space exploration. Mars is an alluring but unforgiving frontier, and its mastery will not come easily. Until then, every spacecraft that embarks on the perilous journey to Mars carries with it humanity's hopes and dreams, along with the sobering knowledge that the Red Planet does not surrender its secrets lightly.
