Why did Mariner 8 fail?

Mariner 8, part of NASA’s Mariner program, experienced a failure on May 8, 1971, just minutes after its launch. The mission aimed to explore Mars, but a rocket failure thwarted its journey. The Atlas-Centaur rocket carrying Mariner 8 deviated from its planned trajectory due to a guidance system malfunction. Attempts to correct the course were unsuccessful, leading to the decision to destroy the spacecraft to prevent any potential risks.

The failure of Mariner 8 underscored the inherent risks and complexities of space exploration. The incident prompted thorough investigations into the root causes, leading to improvements in spacecraft design and launch procedures. Despite this setback, the subsequent success of Mariner 9, launched just a few weeks later, demonstrated the resilience and adaptability of the space exploration community in learning from failures and pushing forward with advancements in planetary exploration.

Is the Mariner 10 still in space?

Mariner 10 is not in space. Launched by NASA on November 3, 1973, Mariner 10 conducted flybys of the planets Mercury and Venus, providing valuable data. After completing its primary mission objectives, Mariner 10 ceased communication in March 1975. The spacecraft remains in a heliocentric orbit, meaning it orbits the Sun, and it is not actively controlled or monitored by Earth. While it is still technically in space, Mariner 10 is no longer operational, and its communication systems have long been silent.
