Call for Letters of Application for Membership in the Joint Dark Energy Mission Interim Science Working Group Scientists at United States institutions are invited to serve as a member of the Joint Dark Energy Mission Interim Science Working Group (ISWG). The members of the JDEM ISWG will provide the JDEM Project Offices at NASA and the Department of Energy (DOE) with scientific assistance during preliminary concept (Pre-Phase A) activities. Near-term activities of the ISWG members will focus primarily on assessing the scientific approach to investigating the nature of dark energy with a medium-class JDEM-probe space mission. This assessment will complement previous analyses of JDEM mission concepts and scientific investigation approaches conducted by the agencies. To avoid conflicts of interest, ISWG members cannot be members of any National Academy of Science Astro2010 "Decadal Survey" panels. |

Mercury Facts Collected By Man In Pottstown
Mercury is the innermost and smallest planet in the Solar System, orbiting the Sun once every 87.969 days. The orbit of Mercury has the highest eccentricity of all the Solar System planets, and it has the smallest axial tilt. It completes three rotations about the axis for every two orbits. The perihelion of Mercury.s orbit precesses around the Sun at an excess of 43 arcseconds per century; a phenomenon that was explained in the 20th century by Albert Einstein.s General Theory of Relativity. Mercury is bright when viewed from Earth, ranging from .2.0 to 5.5 in apparent magnitude, but is not easily seen as its greatest angular separation from the Sun is only 28.3°. Since Mercury is normally lost in the glare of the Sun, unless there is a solar eclipse, Mercury can only be viewed in morning or evening twilight. Comparatively little is known about Mercury; ground-based telescopes reveal only an illuminated crescent with limited detail. The first of two spacecraft to visit the planet was Mariner 10, which mapped only about 45% of the planet.s surface from 1974 to 1975. The second is the MESSENGER spacecraft, which mapped another 30% during its flyby of January 14, 2008. MESSENGER will make one more pass by Mercury in 2009, followed by orbital insertion in 2011, and will then survey and map the entire planet. |

Mission To Mercury Could Solve Solar System SecretsMESSENGER Flies By Mercury's Surface Tuesday
BOULDER, Colo. -- Colorado scientists are hoping to learn big things from the solar system's smallest planet.The spacecraft MESSENGER flew right by the surface of Mercury Tuesday afternoon. It's carrying an instrument made at the Laboratory for Atmospheric and Space Physics at the University of Colorado at Boulder. The instrument is called the Mercury Atmospheric and Surface Composition Spectrometer, or MASCS.Scientists said the instrument will help them determine how Mercury formed."It's an instrument that measures reflected light from the surface of the planet. We analyze the color of that light, and it tells us something about the composition of the surface," said Bill McClintock, developer of the MASCS.McClintock said learning how Mercury formed will unlock more secrets about how the solar system formed. So far, scientists have learned Mercury has a tail cloud like a comet. |

Come join up with us! Get to space as a member! I am James Smith. I sit first Chair for the Office of Tomorrows Mars. I am working on changing the site up and even moving to a new and better server. We are looking for people to help in our task of building up and completing our group. We hgave several ventures on the side to help to self fund the program but without you the reader, follower or member we are unable to do so. So please sign up with us so that we can make the idea of Humans living in space and beyond complete. I have added or Mission statement to this post as I want everyone to understand we are in this for ALL human space flight not the elite nor just a select few. When the colonist came to America they didnt just come with a few things and a couple of elite people. They came with builders, Farmers, housewives, cooks and other everyday occupations. This is how the Human colonies should function as well. Please feel free to contact me personally or apply through the site. My email is

Asteroid Juno Grabs the Spotlight
Toward the end of September, the sun will turn a spotlight on the asteroid Juno, giving that bulky lump of rock a rare featured cameo in the night sky. Those who get out to a dark, unpolluted sky will be able to spot the asteroid's silvery glint near the planet Uranus with a pair of binoculars.
"It can usually be seen by a good amateur telescope, but the guy on the street doesn't usually get a chance to observe it," said Don Yeomans, manager of NASA's Near Earth Object Program Office at JPL. "This is going to be as bright as it gets until 2018."
Juno, one of the first asteroids discovered, is thought to be the parent of many of the meteorites that rain on Earth. The asteroid is composed mostly of hardy silicate rock, which is tough enough that fragments broken off by collisions can often survive a trip through Earth's atmosphere. |
