In 1962, one missing overbar in an Atlas guidance equation helped send Mariner 1 off course, forcing range safety to destroy NASA’s $18.5 million Venus mission less than five minutes after launch

On July 22, 1962, a missing overbar in a guidance formula, combined with a radar hardware failure, sent NASA's first interplanetary probe off course and forced Range Safety to destroy Mariner 1 just 293 seconds after launch.

In 1971, a global dust storm on Mars swallowed the entire planet for weeks, hiding every surface feature from Mariner 9 as it arrived in orbit, and forcing NASA to wait months before the first detailed maps could even begin

When Mariner 9 became the first spacecraft to orbit another planet in November 1971, a global dust storm had already erased every surface feature on Mars. NASA waited four months for the sky to clear — and the mission that followed rewrote everything we thought we knew about the Red Planet.

Every year, roughly 27.7 million tons of Saharan dust cross the Atlantic on trade winds and settle over the Amazon, carrying the phosphorus that keeps the rainforest soil from collapsing into something closer to sand

Every year, NASA satellites track around 27.7 million tons of Saharan dust drifting across the Atlantic to the Amazon, carrying roughly 22,000 tons of phosphorus — almost exactly what the rainforest's rivers wash away. Most of it comes from a single dry lake bed in Chad.

In December 2025, NASA’s Perseverance rover completed the first drives on another planet whose routes were generated by artificial intelligence, travelling 210 and 246 metres along Jezero Crater’s rocky rim after engineers verified the plans on Earth.

The rover's new route-planning partner isn't autonomous—it's a collaborative tool that lets engineers move faster while maintaining tight control, marking a shift in how humans and machines share the work of exploring Mars.
