Responding To Potential Asteroid Redirect Mission Targets
2014-02-15 06:26:56

NASA/Jet Propulsion Laboratory One year ago, on Feb. 15, 2013, the world was witness to the dangers presented by near-Earth Objects (NEOs) when a relatively small asteroid entered Earth's atmosphere, exploding over Chelyabinsk, Russia, and releasing more energy than a large atomic bomb. Tracking near-Earth asteroids has been a significant endeavor for NASA and the broader astronomical community, which has discovered 10,713 known near-Earth objects to date. NASA is now pursuing new...

NASA Asteroid Initiative

NASA In June of last year, NASA Administrator Charlie Bolden spoke to the United Nations Committee on Peaceful Uses of Outer Space (COPUOS) and shared with the international community what NASA is doing to detect and track asteroids. He also engaged the United Nation’s support for NASA’s mission to find, capture and redirect an asteroid to lunar orbit, and then send humans to explore it by 2025. Following Bolden’s presentation, Mazlan Othman, director of the U.N. Office for Outer...

Astronomers Get A Good Look Inside Asteroid Itokawa

[ Watch the Video: What's Inside An Asteroid? ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers, using the European Southern Observatory’s (ESO) New Technology Telescope (NTT), have discovered that asteroids have a highly varied internal structure. The astronomers used the instrument to look at different parts of the asteroid Itokawa, which was the target of the Japanese spacecraft Hayabusa in 2005. This spacecraft took samples of an asteroid for the first time and...

MIT Scientists Claim Rogue Asteroids Are More Common Than Thought

[ Watch the Video: What Happens When Asteroids Go Rogue? ] Lee Rannals for redOrbit.com - Your Universe Online Scientists from MIT and the Paris Observatory claim that rogue asteroids are more common than previously thought. Previously, scientists believed that asteroids were static and remained near the sun. However, observations in the last decade have revealed that asteroids show up in unexpected places in space. “That [theory] has been completely turned on its head,”...

Brett Smith for redOrbit.com - Your Universe Online Once a hibernating craft drifting silently through space, NEOWISE was repurposed and reactivated last month with a new mission – find asteroids and other potentially hazardous near-Earth objects (NEO). On Thursday, NASA announced that the probe has identified 857 minor bodies in our solar system, including 22 NEOs and four comets, in its first 25 days of operation. Three of these NEOs are new discoveries measuring hundreds of feet in...

WASHINGTON, Jan. 22, 2014 /PRNewswire-USNewswire/ -- Scientists using the Herschel space observatory have made the first definitive detection of water vapor on the largest and roundest object in the asteroid belt, Ceres. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) Plumes of water vapor are thought to shoot up periodically from Ceres when portions of its icy surface warm slightly. Ceres is classified as a dwarf planet, a solar system body bigger than an asteroid...

Dwarf Planet Ceres Caught Spewing Out Water Vapor

[ Watch the Video: Ceres Lets Of A Little Steam ] Lee Rannals for redOrbit.com - Your Universe Online Water vapor has been discovered around the dwarf planet Ceres thanks to new data from the Herschel Space Observatory. Ceres is the largest object in the asteroid belt and sits between the orbits of Mars and Jupiter. Scientists believe that Ceres is layered with a rocky core and icy outer mantle, which has significant implications for our understanding of the evolution of the Solar...

Asteroid Discovery Comes After NASA Reactivates NEOWISE
2014-01-08 10:07:31

Brett Smith for redOrbit.com - Your Universe Online Considering NASA’s recent budget cuts, re-purposing the space agency’s assets is more important than ever. One asset re-purposed by NASA, the Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE), has made its first discovery since coming out of hibernation last year: a never-before-seen asteroid dubbed 2013 YP139. Formerly known as the Wide-field Infrared Survey Explorer (WISE), the orbiter was shut down in 2011 after...

[ Watch the Video: Binary Asteroid System Discovered ] Brett Smith for redOrbit.com - Your Universe Online An undergraduate astronomy class for non-astronomy majors at the University of Maryland has made a rare discovery that was completely overlooked by professional scientists: a pair of asteroids that orbit and regularly eclipse each other located in the main asteroid belt between Mars and Jupiter. There are currently fewer than 100 known eclipsing binary asteroids and the...

WASHINGTON, Jan. 7, 2014 /PRNewswire-USNewswire/ -- NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft has spotted a never-before-seen asteroid -- its first such discovery since coming out of hibernation last year. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) NEOWISE originally was called the Wide-field Infrared Survey Explorer (WISE), which had made the most comprehensive survey to date of asteroids and comets. The spacecraft was shut...

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

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...
