Mars may take on a very Saturn-like look in the future.
The red planet’s largest moon, Phobos, has an inward-moving orbit that is sending it on a destructive path toward Mars’ strong gravitational grasp. This could cause the moon to break apart and disintegrate into a planetary ring some 20 million to 40 million years from now, according to a study published Monday in the journal Nature Geoscience.
“This research tells us both about how the Martian system may change in the future, and about the processes that might have affected any other inwardly migrating moons that self-destructed in our solar system’s past,” Dr. Benjamin Black, a postdoctoral researcher at the University of California, Berkeley and a co-author of the new study, told The Huffington Post.
Black and his colleague Tushar Mittal, a graduate student at the university, used a combination of simulations and models to analyze how Phobos’ orbit may evolve. They took a close look at the physical stresses Mars exerts on Phobos as the moon’s orbit causes it to gradually veer inward.
Phobos is a delicate moon with lots of pores and rubble on its surface, which researchers say could contribute to it eventually crumbling to pieces under the red planet’s powerful gravitational pull. These fragmented pieces would then orbit Mars, forming a planetary ring.
The destruction of a planet’s moon or another passing object, such as an asteroid or comet, is one of the most common ways in which planetary ring systems form.
Saturn’s rings may have formed in a similar way, and some scientists speculate that Neptune’s moon Triton might be falling apart currently, causing it to reach the same doomed fate, Nature magazine reported.
The researchers noted that our own moon is slowly moving away from Earth, so it likely —> Read More
After the successful restart of the Large Hadron Collider and its first months of data taking with proton collisions at a new energy frontier, the LHC is moving to a new phase, with the first lead-ion collisions of season 2 at an energy about twice as high as that of any previous collider experiment. —> Read More
This illustration shows a star behind a shattered comet. Observations of the star KIC 8462852 by NASA’s Kepler and Spitzer space telescopes suggest that its unusual light signals are likely from dusty comet fragments, which blocked the light of the star as they passed in front of it in 2011 and 2013. The comets are thought to be traveling around the star in a very long, eccentric orbit. Credit: NASA/JPL-Caltech
The story of KIC 8462852 appears far from over. You’ll recall NASA’s Kepler mission had monitored the star for four years, observing two unusual incidents, in 2011 and 2013, when its light dimmed in dramatic, never-before-seen ways. Models to explain its erratic behavior were so lacking that some considered the possibility that alien megastructures built to capture sunlight around the host star (think Dyson Spheres) might be the cause.
But a search using the SETI Institute’s Allen Telescope Array for two weeks in October detected no significant radio signals or other signs of intelligent life emanating from the star’s vicinity. Something had passed in front of the star and blocked its light, but what?(…)

Crews and cargo shipments will be coming and going at the International Space Station during a busy December in space. Two resupply ships will arrive, one cargo craft will leave and an Expedition 45 trio will head home before an Expedition 46 trio replaces it.
NASA’s Operation IceBridge, an airborne survey of polar ice, recently finalized two overlapping campaigns at both of Earth’s poles.
Global catastrophes over the last 20 years includes 6,457 recorded floods, storms, heatwaves, and the like. Continue reading → —> Read More

Author’s note: In the wake of the November 13th terrorist attacks, the French Space Agency CNES canceled the celebration of the 50th anniversary of the launch of Asterix. This post commemorates the launch of France’s first satellite 50 years ago this week, and pays a small tribute to the noblest of human endeavors, namely the exploration of space and the pioneering spirit of humanity exemplified by a heroic nation.(…)
