In 1971, the Soviet Union’s Mars 3 became the first spacecraft to soft-land successfully on Mars—but it transmitted for just 14.5 seconds before falling silent, giving it the shortest successful surface mission in Martian history.

6+ day, 11+ hour ago   (897+ words) Mars 3 achieved the first soft landing on Mars, then lost contact within seconds. The surviving records distinguish a successful arrival from a surface investigation that never developed. By The Long View · Edited by Lachlan Brown Published September 8, 2026 · How we edit…...

At the summit of Mount Thor on Baffin Island, a cliff face drops 1,250 metres straight down at an average overhang of 15 degrees past vertical, meaning a person falling with arms spread could remain in open air for roughly 26 seconds before hitting the talus below

1+ week, 1+ hour ago   (1176+ words) On Baffin Island, a wall of ancient granite leans 15 degrees past vertical for 1,250 metres, producing the longest uninterrupted freefall path on any cliff on Earth.

When Hunga Tonga erupted underwater in 2022, it fired so much water vapour into the upper atmosphere that it measurably increased the total amount of water in the stratosphere, and scientists are still tracking how it may nudge the climate for years.

2+ week, 6+ day ago   (153+ words) A volcanic explosion in the South Pacific delivered an unprecedented amount of water vapor directly into Earth's upper atmosphere, potentially altering global temperatures in ways scientists are only beginning to understand.

The rainforest is not the lungs of the Earth — the ocean is. Microscopic phytoplankton drifting in the sunlit top layer of the sea produce roughly half of all the oxygen on the planet, more than every tree and forest combined

Early Neanderthals were probably striking sparks to make fire in England 400,000 years ago — roughly 350,000 years earlier than the previous convincing evidence, revealed by baked earth, heat-shattered handaxes and pieces of pyrite found at Barnham.

4+ week, 1+ day ago   (791+ words) A repeatedly heated patch of clay, fire-damaged tools and locally rare pyrite form the earliest convincing archaeological case for deliberate fire-making, although no human remains identify the makers directly.
