If NASA had asked astronaut Frank Rubio, well in advance, if he would like to spend a full year aboard the International Space Station, he likely would have turned it down. But that’s how it turned out anyway, when trouble with his crew’s Soyuz ferry ship forced them to extended a six-month stay to 12.
How long will the annular solar eclipse last on Oct. 14?
The duration of the annular solar eclipse depends on the viewing location. We look at where the longest 'ring of fire' will occur and how long the eclipse will last.

Solar Sails Could Reach Mars in Just 26 Days
A recent study submitted to Acta Astronautica explores the potential for using aerographite solar sails for traveling to Mars and interstellar space, which could dramatically reduce both the time and fuel required for such missions. This study comes while ongoing research into the use of solar sails is being conducted by a plethora of organizations along with the successful LightSail2 mission by The Planetary Society, and holds the potential to develop faster and more efficient propulsion systems for long-term space missions.

This 3D Simulation of a Supernova Needed 5 Million Hours of Supercomputing
When the largest stars in the Universe run out of fuel, they detonate as supernovae, collapsing inward and leaving behind a neutron star, black hole, or just wholly vaporizing. What’s happening inside the unfolding explosion is difficult to understand, and especially so for so-called exotic supernovae, the rarest and brightest types of stellar explosions.
