Watch the Video: Dawn Spacecraft's Farewell Portrait of Giant Asteroid Vesta Lee Rannals for redOrbit.com - Your Universe Online The Dawn spacecraft will be departing from asteroid Vesta on September 4 and will head out on a two-and-a-half-year journey towards the dwarf planet Ceres. The spacecraft arrived at Vesta in July 2011 after launching in 2007 on a 3-billion-mile journey towards the asteroid belt. NASA said Dawn will be reaching Ceres in early 2014. Dawn will spiral away...

Lee Rannals for redOrbit.com - Your Universe Online It may seem like poppycock, but the methods utilized in the popular movie Armageddon wouldn't work, according to science. Students from the University of Leicester were the ones to burst everyone's bubble by using a popular arch-nemesis when it comes to battling the reality of a movie: physics. In the 1998 film, Bruce Willis, an old-drilling platform engineer, must save Earth from being pummeled by an asteroid by drilling to the...

Meteorites Hold Secrets Of Earth's Formation
2012-07-23 05:32:42

redOrbit Staff & Wire Reports - Your Universe Online Scientists attempting to better understand the formation and the present-day layering of planet Earth have turned to ancient meteorites -- meteorites which they say could hold important clues to some of the Solar System's earliest chemical processes. Those meteorites are known as diogenites, and researchers from the Carnegie Institution, the Scripps Institution of Oceanography, and the University of Maryland studied nine samples...

Standard Model Does Little To Explain Why Earth Is So Dry
2012-07-18 10:59:10

Lawrence LeBlond for redOrbit.com - Your Universe Online Despite seventy percent of the Earth´s surface being covered by water, in reality the whole of the planet is only made up of 1 percent water, making it relatively dry compared to the gas giants, such as Jupiter and Neptune. And now, that dryness, which has long perplexed scientists, has been explained by a team of scientists working at the Space Telescope Science Institute (STSI) in Baltimore, Maryland. The standard model...

Lee Rannals for redOrbit.com - Your Universe Online Virgin Galactic hasn't even taken a tourist to space yet, but the company is already expanding its means by partnering with Planetary Resources to launch tools into space. Planetary Resources will be relying on the transportation of Virgin Galactic to launch a series of spacecraft, including the Arkyd-100 low-Earth orbit (LEO) space telescopes. The company's goal is to eventually mine asteroids, but first has to take a series of...

Privately-Funded Deep Space Mission Planned

Lee Rannals for redOrbit.com - Your Universe Online Former astronauts are making plans to build and launch their own space telescope to track down dangerous asteroids. The B612 Foundation, which is made up of former NASA astronauts and U.S. scientists, said it plans to launch the first privately funded deep space mission. The company said that its Sentinel mission would see that a space telescope be placed in orbit around the sun. Ed Lu, a former NASA astronaut who flew aboard...

Rosetta Reveals History Of Asteroid Lutetia
2012-06-27 04:44:56

[ Watch the Video] The long and tumultuous history of asteroid Lutetia was revealed by ESA´s Rosetta spacecraft as it raced past this large, ancient asteroid. This spectacular movie shows a sequence of images snapped by Rosetta as it flew past the main-belt asteroid on 10 July 2010. The sequence begins nine and a half hours before Rosetta made its closest pass, when the asteroid still appeared like a distant tumbling speck seen from a distance of 500 000 km. Surface features...

Lee Rannals for redOrbit.com An asteroid about the size of a football stadium may slightly have a chance of impacting Earth in 2040, but new estimates show it's hardly a threat. The space rock, measuring about 460-feet in size, has a likelihood of missing Earth greater than 99 percent, according to the recent findings by scientists at a May 29 workshop at NASA's Goddard Space Flight Center. "While there is general consensus there is only a very small chance that we could be dealing...

Johann Daniel Titius was born on January 2, 1729 in Konitz, Royal Prussia. He was a professor at Wittenberg. He is most famous for the Titius-Bode law, which helped him find the existence of a minor planet at 2.8 AU from the sun in 1766. The planet was later named Ceres. Titius died in Wittenberg on December 11, 1796. To his honor, the Titius asteroid in 1998 and the Titius lunar crater are named after him.

Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

Solar System
2012-10-22 06:09:41

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
