A pristine comet has swept past Mars, passing it closer than one-third of the distance from the Earth to the Moon. Astronomers had a unique chance to observe the celestial body up close, as such an astronomical event occurs just once in a million years.
Mimas, one of Saturn’s moons (nicknamed ‘Death Star’) has a telltale wobble that leads scientists to believe the orb may have underground water ‒ or even a subterranean ocean ‒ according to a new study.
The Air Force’s top-secret space plane landed in California on Friday morning after nearly two years orbiting Earth on a classified mission. The robotic spacecraft’s purpose remains a mystery, though surveillance is a likely candidate.
For eight months, six astronauts will be essentially locked into a small dome in Hawaii as NASA attempts to study the consequences of living the quiet, lonely lifestyle that humans would experience on Mars.
Comet Siding Spring is expected to travel exceptionally close to Mars at 126,000 mph (202,000 kph) on October 19, according to NASA, which says it will strategically maneuver its craft orbiting the Red Planet away from the comet’s impacts.
A blood-red moon has dazzled stargazers for the second time this year, presenting a spectacular view in the skies over the eastern hemisphere. The rare optical phenomenon has been best seen from Asia, Australia, North America and Russia’s Pacific region.
To dramatically cut the cost of its future manned missions to Mars, NASA is testing a sci-fi sounding technique of placing the crew in stasis. The deep sleep conditions would also reduce psychological challenges for the astronauts during the 180-day trip.
For the first time in over a year, a NASA astronaut has performed routine maintenance outside the International Space Station. It was a maiden spacewalk for both American Reid Wiseman and German Alexander Gerst who finished a job aborted last December.
Once the fourth-biggest lake in the world, the eastern basin of the Aral Sea in central Asia is now completely dry. It is the result of a Soviet-era project to divert rivers for agriculture and a lack of rainfall at its source.
