Is Comet Elenin Going To Be An Extinction Level Event Or Will It Take More Than One Of These Objects Part 2 Of 3

WHY HASN'T LEONID ELENIN BEEN IN THE MEDIA?Additionally, why is Leonid Elenin so elusive? Is he really real, or is he just a figure that was put out there to deflect our attention or to hide something regarding the event? Looking on LinkedIn, he doesn't have his profile out there in a way that he can gain connections, or others can interact with him. In fact, it only shows that he has 20 connections, which seems really low for someone with a large discovery like Comet Elenin."Comet Elenin (C/2010 X1) made its debut on December 10th when Leonid Elenin, an observer in Lyubertsy, Russia, remotely acquired four 4-minute-long images using an 18-inch (45-cm) telescope at the ISON-NM observatory near Mayhill, New Mexico. Follow-up images by Aleksei Sergeyev and Artyom Novichonok at Maidanak Observatory in Uzbekistan revealed more about the new find: it had a teardrop-shaped, very diffuse coma just 6 arcseconds across and a tiny tail."What is strange is that the word ELE NIN may be an acronym for Extinction Level Event Near Impact Nemesis. It is coming out of Leo's direction (Leonid). It is going to be very very (0.24 AU) close to Earth and we will align with it two more times and cross it's debris field. http://thegreathate.wordpress.com/2011/04/04/leonid-elenin/ Will this actually be an Extinction Level Event? There was a practice event in 2005 when a plan was developed called "Deep Impact". Here is an excerpt... The launch window for Deep Impact opens on 6 Jan 2004. Deep Impact consists of twospacecraft - an impactor and a flyby. There is a one-year heliocentric orbit followed by anencounter with Earth in December 2004, at which time targeting techniques will be tested and calibrations will be performed using the moon. The impact with comet 9P/Tempel 1 will occur in early July 2005. One day before impact, the impactor and flyby spacecraft separate. The flyby spacecraft then slows down to allow time to observe the cometary nucleus after the impact... (about 14 minutes) and diverts so as to miss the nucleus by approximately 500 km. The instruments on the flyby spacecraft are body mounted so the spacecraft rotates to point the instruments at the nucleus during the approach. Some data are transmitted continuously in real time while all data are stored on board. When the spacecraft has rotated 45^0, nominally at a range of 700 km from the nucleus, the rotation is stopped at which point dust shields have been rotated into the direction of the velocity vector to protect the spacecraft through the innermost coma. After closest approach when the densest part of the coma has been transited, thespacecraft turns to take look-back observations of the comet. All data are transmitted to Earth within a few days after the encounter.Delivery date Archive Products08/31/2003 Earth based pre-encounter spectra and images.03/31/2004 Data collected in the 30 days after launch.03/31/2005 Calibration files and payload tests during Earth flyby.12/31/2005 Earth based data leading up to impact.Spacecraft measurements through impact.03/31/2006 Earth based post impact data.Read more at http://pdssbn.astro.umd.edu/missions/deepimpact/deep impact pdmp.pdfAnd then there's this...NASA SUN-WATCHING SATELLITE SPOTS COMET ELENIN IN DEEP SPACEA NASA spacecraft aimed at the sun shifted its unblinking gaze to an approaching comet last week to snap a new photo of the icy object as it flew by.The image shows the comet Elenin as it passed within 4.3 million miles (7 million kilometers) of one of NASA's twin Stereo sun-watching spacecraft during a series of deep space photo sessions that began on Aug. 1. NASA rolled the Stereo-B satellite to give its instruments a view of the comet flyby, officials said.From Stereo's observations, the fuzzy comet Elenin can be seen streaking across a small portion of the sky.The comet was seen by Stereo's HI-2 telescope between Aug. 1 to 5, and by the higher resolution HI-1 telescope between Aug. 6 to 12, NASA officials said. Stereo mission scientists planned to take photos for one-hour every day through Aug. 12....Conspiracy theorists say a planet, known as Nibiru, will swing in from the outskirts of our solar system and collide with Earth and wipe out humanity in 2012. Since no rogue planet has been found in the outer solar system, some people have argued that comet Elenin will be the true culprit in the Nibiru-Earth collision.NASA has dismissed the notion that comet Elenin is anything other than a dim, wimpy comet. It poses no threat to Earth, making its closest pass at a distance roughly 100 times farther than the distance from Earth to the moon.http://www.space.com/12603-comet-elenin-photo-nasa-stereo-spacecraft.html

Change 3 Lunar Probe Ready To Launch Weather Favorable

Change 3 Lunar Probe Ready To Launch Weather Favorable
The weather at the launch site for China's Chang'e-3 lunar ask behest be auspicious, a stuck-up graphic designer together with Xichang Satellite Mail Staple has said. Jiang Xiaohua, a stuck-up meteorologist, told Xinhua on Sunday that the weather behest be pious for the piece daytime for the launch. Offer behest be no rain. Jiang said cold weather and stuck-up winds may collection challenges as heat up variations behest take up the preference on how extensively agitate behest be enviable. Disposed winds may handling the rocket's stream. Porcelain behest launch Chang'e-3 lunar ask to the moon at 1:30 a.m. Monday (17:30 GMT Sunday) from the launch center. It behest be the first time Porcelain has sent a spacecraft to supple land on the surface of an extraterrestrial physique.

Facilities at the debut site are in pious circumstances and measures are going well, according to the foundation.

The ask behest be launched to spin aboard an patronizing Yearning March-3B carrier which is spread than three meters in diameter and 56.4 meters high.

The deputation behest be the 25th launch of the Yearning March-3B, which is the most strong launch cunning in the Yearning March rapid.

Engineers wolf adopted technologies of high-precision government and control, many narrow piece launches, transmission system for remote sensing, and reduction of the rocket's deadweight, said Cen Zheng, vitality system commanding officer of the deputation.

Chang'e-3 comprises a lander and a moon itinerant called "Yutu" (Lush Rabbit). The lunar ask behest land on the moon in mid-December if something goes according to plan.

"Chinese scientists wolf through practical breakthroughs for the Chang'e-3 deputation, which behest be the most stylish and petulant crate in China's space exploration," Wu Zhijian, narrator together with Demand Charge of Science, Tackle and Production for Family Defence said. "Spread than 80 percent of the technologies adopted in the deputation are new," he expand.

Tasks for Yutu addition surveying the moon's geological android and surface substances, while looking for intuitive worldly goods.

So far, scarcely the United States and the elderly Soviet Union wolf soft-landed on the moon.

After incoming lunar spin, Chang'e-3 behest go consume six stages of deceleration to perch from 15 km better to the lunar surface.

The soft-landing processes of the U.S. and elderly Soviet Union's unmanned spacecraft had no ability to balance or avert obstacles. Chang'e-3, on the other hand, can accurately point of view landforms at the landing site and advise the safest spots on which to land.

In alert to land high-speed, the ask is keen together with high-precision, fast-response sensors to suffering its wave your arms and location. The unpredictable central theme engine (absolutely meant and through by Chinese scientists) can follower up to 7,500 newtons of central theme.
