Perseverance rover captured a 360-degree panorama of a region on Mars called “Bright Angel,” where a river flowed billions of years ago. - NASA/JPL-Caltech/ASU/MSSS
At least two-thirds of Mars' surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; [4] Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there.

The hypothesis also speculates that artifacts from past civilizations could be found on the Moon and Mars, where erosion and tectonic activity are less likely to erase evidence. The concept of pre-human civilizations has been explored in popular culture, including novels, television shows, short stories, and video games.
In its ancient past, Mars likely contained many of the necessarily ingredients for microbial life to flourish on its surface. Now, a new discovery by NASA’s Perseverance rover shows a trifecta ...
The Mars carbonate catastrophe was an event that happened on Mars in its early history. Evidence shows Mars was once warmer and wet about 4 billion years ago, that is about 560 million years after the formation of Mars. Mars quickly, over a 1 to 12 million year time span, lost its water, becoming cold and very dry.

[150] 9 November 2013: Plesetsk, Russia: 2: Two workers cleaning out a propellant tank died when exposed to poisonous nitrogen tetroxide gases within the tank ...
NASA's 38-year-old dead satellite has returned to Earth without incident. The Defense Department has confirmed that the Earth Radiation Budget Satellite (ERBS) reentered the atmosphere off the ...
The spacecraft reached an altitude of 120 km before reentry. Mars 1962A was a Mars flyby mission, launched on October 24, 1962, and Mars 1962B an intended first Mars lander mission, launched in late December of the same year (1962). Both failed from either breaking up as they were going into Earth orbit or having the upper stage explode in ...
