Pee power: Urine-loving bug churns out space fuel
Researchers have gained insights into a bacterium that transforms ammonium, the ingredient of urine, into hydrazine, a rocket fuel.
In the Shadow of Saturn
In the shadow of Saturn, unexpected wonders appear. The robotic Cassini spacecraft now orbiting Saturn drifted in giant planet’s shadow for about 12 hours in 2006 and looked back toward the eclipsed Sun. Cassini saw a view unlike any other. First, the night side of Saturn is seen to be partly lit by light reflected from its own majestic ring system. Next, the rings themselves appear dark when silhouetted against Saturn, but quite bright when viewed away from Saturn, slightly scattering sunlight, in this exaggerated color image. Saturn’s rings light up so much that new rings were discovered, although they are hard to see in the image. Seen in spectacular detail, however, is Saturn’s E ring, the ring created by the newly discovered ice-fountains of the moon Enceladus and the outermost ring visible above. Far in the distance, at the left, just above the bright main rings, is the almost ignorable pale blue dot of Earth.
Space Junk Problem Reaches Tipping Point
It’s bad news for all you aspiring space tourists out there. Soon, the only ticket into space may be of the suborbital variety and nothing more ambitious, like actually flying into orbit. Earth is now surrounded by so much space junk that a leading expert on the issue has declared that we are at a “tipping point” — it may soon become too dangerous to venture into low-Earth orbit (LEO) through fear of having a manned spaceship punctured or a communications satellite trashed.
