Mission News and Science
Modified from: http://www.ras.org.uk/index.php?option=com_content&task=view&id=982&Itemid=2
Recent evidence suggests that Mercury might have been created from a larger parent body that was involved in a catastrophic collision. New computer simulations of Mercury’s formation suggest the fate of material blasted out into space when a large proto-planet collided with a giant asteroid 4.5 billion years ago. The simulations, which track the material over several million years, might shed light on why Mercury is denser than expected and show that some of the ejected material would have found its way to the Earth and Venus.
The theory suggests that a large fraction of the debris eventually fell back onto Mercury. The simulations showed that it would take up to 4 million years for 50% of the particles to land back on the planet and in this time many would be carried away by solar radiation. This explains why Mercury retained a much smaller proportion than expected of the material in its outer layers. While this is only a small fraction, it illustrates that material can be transferred between the inner planets relatively easily. Given the amount of material that would have been ejected in such a catastrophe, it is likely that there is a reasonable amount of proto-Mercury in the Earth.
Hubble Finds "Tenth Planet" is only Slightly Larger Than Pluto
Modified from: http://www.nasa.gov/mission_pages/hubble/hst_xena_20060410.html
For the first time, NASA's Hubble Space Telescope has seen distinctly the "tenth planet," currently nicknamed "Xena," and has found that it is only slightly larger than Pluto. Because Xena is smaller than previously thought, but comparatively bright, it must be one of the most reflective objects in the solar system. The only object more reflective is Enceladus, a geologically active moon of Saturn whose surface is continuously recoated with highly reflective ice by active geysers. Xena's bright reflectivity is possibly due to fresh methane frost on its surface. The object may have had an atmosphere when it was closer to the sun, but as it moved to its current location farther away this atmosphere would have "frozen out," settling on the surface as frost. Another possibility is that Xena leaks methane gas continuously from its warmer interior. When this methane reaches the cold surface, it immediately freezes solid, covering craters and other features to make it uniformly bright to Hubble's telescopic eye.
Hubble will be used in the future to study other recently discovered Kuiper Belt objects that are almost as large as Pluto and Xena. The Kuiper Belt is a vast ring of primordial icy comets and larger bodies encircling Neptune's orbit. Finding that the largest known Kuiper Belt object is a virtual twin to Pluto may only further complicate the debate about whether to categorize the large icy worlds that populate the belt as planets. If Pluto were considered to be the minimum size for a planet, then Xena would fulfill this criterion, too. In time, the International Astronomical Union will designate the official name.
NASA Clarifies Information on Comet Approach
NASA recently issued information about Comet 73P/Schwassmann-Wachmann, which will be passing Earth as it approaches the point nearest the sun during its 5.5 year orbit. Astronomers have been observing the comet for more than 75 years. The trajectory of this comet has been monitored and refined over time, and its path around the sun is well understood.
The comet has broken into more than 40 fragments. Any pieces resulting from the breakup of its main body will come no closer than 5.5 million miles to Earth, or more than 20 times the Earth-moon distance, during its closest approaches May 12 - 28. Neither the main comet nor any of its pieces pose a danger to Earth.
The main fragment of the comet will pass closest to Earth on May 12 at a distance of approximately 7.3 million miles. It will be visible to small telescopes during the morning hours in the constellation Vulpecula. NASA's Spitzer Space Telescope will observe the comet in
May. NASA's Hubble Space Telescope has also viewed it. For images and more information about the comet, visit: http://www.nasa.gov/hubble.
Titan’s Sandy Oceans
Until a couple of years ago, scientists thought the dark equatorial regions of Titan might be liquid oceans. New radar evidence shows they are seas -- but seas of sand dunes like those in the Arabian or Namibian Deserts, a University of Arizona member of the Cassini radar team and colleagues report in Science (May 5).
Radar images taken when the Cassini spacecraft flew by Titan last October show dunes 330 feet high that run parallel to each other for hundreds of miles at Titan's equator. One dune field runs more than 930 miles long, said Ralph Lorenz of UA's Lunar and Planetary Laboratory.
Ten years ago, scientists believed that Saturn's moon Titan is too far from the sun to have solar-driven surface winds powerful enough to sculpt sand dunes. They also theorized that the dark regions at Titan's equator might be liquid ethane oceans that would trap sand. But researchers have since learned that Saturn's powerful gravity creates significant tides in Titan's atmosphere, driving winds. Saturn's tidal effect on Titan is roughly 400 times greater than our Moon's tidal pull on Earth.
The researchers' model of Titan suggests tides can create surface winds that reach about one mile per hour (a half-meter per second). "Even though this is a very gentle wind, this is enough to blow grains along the ground in Titan's thick atmosphere and low gravity," Lorenz said. Titan's sand is a little coarser but less dense than typical sand on Earth or Mars. "These grains might resemble coffee grounds."
Did You Know?
The Moon has Alps
Might there some day be skiing on the Moon? The moon's dust-covered slopes are good places to ski. There's plenty of powder, moguls and only 1/6th of Earth’s gravity holding humans down.
Modified from: http://www.universetoday.com/am/publish/lunar_olympics.html?922006
And there's a perfect spot for the Olympic Village: the crater Plato. Plato is flat-bottomed, filled with raw materials for building stadia and habitats, and Plato is near the lunar Alps.
The lunar Alps are a range of mountains on the moon named after the Alps of Europe. They are similar to their Earthly counterparts in height, breath and spectacle. You can see the lunar Alps using a small backyard telescope. Although the two Alps look much alike, they formed in different ways. The Alps of Earth grew over a period of millions of years. Powered by plate tectonics, sections of Earth's crust pushed together, squeezing the land to produce jagged mountains. The range stretches from France through Italy all the way to Albania; the tallest peak is Mont Blanc, 15,700 feet high. The Alps of the moon were formed in an instant some 4 billion years ago when a huge asteroid struck and formed a big crater and the surrounding Alps.
In those early days, lunar Alps were probably as jagged and rough as the Alps of Earth. But in eons that followed, meteoroids relentlessly pounded the moon, smashing rocks into dust and blunting the sharp edges of mountain peaks. Today's lunar Alps are a bit shorter (the moon's Mont Blanc is only 11,800 feet high) and a lot smoother than their terrestrial counterparts—perfect for Olympics.
