UW study: Flaw in rover tests risks future Mars missions
New computer simulations reveal a critical flaw in how space agencies test rovers, leading to overly optimistic predictions for missions on the moon and Mars.
NASA’s New Horizons pilots by starlight from 5B miles away
By measuring the apparent shift of nearby stars from its vantage point billions of miles away, NASA's New Horizons spacecraft successfully demonstrated the first-ever method of interstellar navigation.
Study: Mars self-regulated as a desert planet
New research suggests a negative feedback loop involving carbon-trapping rocks may have doomed Mars to become a self-regulating desert planet with only fleeting periods of habitability.
The Dormant Viruses That Wake Up in Astronauts
Because there’s a good chance that right now, you have at least one virus that’s been hiding inside of you for years, lying dormant.
NASA’s DART asteroid impact unleashed unexpected boulder swarm, study finds
A new study reveals that NASA's DART asteroid impact unleashed a massive barrage of boulders that carried more momentum than the spacecraft itself, complicating future planetary defense efforts.
‘Extraordinary claims require extraordinary evidence’ − an astronomer explains how much evidence scientists need to claim discoveries like extraterrestrial life
The universe is filled with countless galaxies, stars and planets. Astronomers may find life one day, but they…
