(click to view the full-size image) This oblique view of the lower mound in Gale Crater shows layers of rock that preserve a record of environments on Mars. Here, orbiting instruments have detected signatures of both clay minerals and sulfate salts, with more clay minerals apparent in the foreground of this image and fewer in higher layers. This change in mineralogy may reflect a change in the ancient environment in Gale Crater. Mars scientists have several important hypotheses about how these minerals may reflect changes in the amount of water on the surface of Mars. The Mars Science Laboratory rover, Curiosity, will use its full suite of instruments to study these minerals to provide insights into these ancient Martian environments. These rocks are also a prime target in the search for organic molecules since these past environments may have been habitable -- able to support microbial life. Scientists will study how organic molecules, if present, vary with mineralogical variations in the layers to understand how they formed and what influences their preservation. The smaller hills in this view may provide clues to the modern water cycle on Mars. They contain sulfate salts that have water in them, and as temperatures warm into summer, some of that water may be released to the atmosphere. As temperatures cool, they may absorb water from the atmosphere. The Mars Science Laboratory team will investigate how water is exchanged between these minerals and the atmosphere, helping us understand Mars' modern climate. The hills are particularly useful for this investigation because different parts of the hills are exposed to different amounts of sunlight and thus to different temperatures. Curiosity will be able to compare the water in these contrasting areas as part of its investigations. This three-dimensional perspective view was created using visible-light imaging by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter and the High Resolution Stereo Camera on the European Space Agency's Mars Express orbiter. Three-dimensional information was derived by stereo analysis of image pairs. The vertical dimension is not exaggerated. Color information is derived from color imaging of portions of the scene by the High Resolution Imaging Science Experiment camera. The Mars Science Laboratory spacecraft is being prepared for launch on Nov. 25, 2011. In a prime mission lasting one Martian year -- nearly two Earth years -- after landing, researchers will use the rover's tools to study whether the landing region has had environmental conditions favorable for supporting microbial life and for preserving clues about whether life existed.

These are the voyages of the starship enterprises to go where no man has gone before. captains log 11.49 Mr. SPOCK .L.T. KESLO ARE due back on the enterprise soon after checking out class m planet near the just discovered velta region of space. captain Kirk was comfortable at the command seat of the enterprise the 5-year mission of the 1701 u.s.s .enterprise would come to an end with one year kirk knew would never command a starship again because soon he would be promoted Admiral and given a dull desk job. Engineering chief commander Scott's voice rang out. Kelso has teleported back up from the enterprise captain but Spock is not here neither is he on the ship!
PROLOGUE Somewhere in the outskirts of Quezon City, Philippines. [This Sci-fi TL will be grisly & graphic: viewer discretion advised] It was a Monday night in a small secluded town & Emma Barboarda was facing a large waterfall next to the cave. It was 10:00 PM & she had been having a problem with solving a nagging itch.... Meanwhile, Vivoree Escamilla was one of the bullies of Emma from school. She had followed Emma secretly all the way to the river & hid behind one of the large rocks "What's this Emma girl hiding ?" Little did Vivoree know, she would see a grisly eye-opener as Emma revealed her true identity..... More on this later...
