Asteroid Subject Of Future NASA Mission Gets New Name
2013-05-02 04:56:09

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online NASA's Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) spacecraft, scheduled to be launched in 2016, will touch down on an asteroid in 2018. Then, after collecting samples from the surface, the probe will rocket back to Earth, returning its find to be studied by terrestrial scientists by 2023. But project leaders noticed that the asteroid in question, asteroid (101955)...

Monitoring Elusive Collisions In Space
2013-04-24 06:09:40

April Flowers for redOrbit.com - Your Universe Online Asteroids and other objects in our solar system collide often, but researchers are not always able to detect or track such impacts from Earth. This means that we are sometimes caught unaware by the "rogue debris" created by the impacts. New research from the University of California, Los Angeles, has devised a method to monitor these types of collisions in interplanetary space. The team used a new method to determine the mass of...

At a major planetary defense conference in Flagstaff, AZ, last evening, the Planetary Society announced the winners of its 2013 Shoemaker Near Earth Object (NEO) grants and was recognized itself for the Society´s long history of international leadership in the detection and mitigation of threatening asteroids, and other planetary discoveries. “As the Chelyabinsk impact demonstrated, asteroid impacts happen; they are dangerous, destructive, with no regard for human life,”...

Asteroid Tracking Sensor Passes Key Test
2013-04-16 07:07:54

April Flowers for redOrbit.com - Your Universe Online A critical design test for an infrared sensor that could improve NASA's future ability to detect and track asteroids and comets has been passed. The Near Earth Object Camera's (NEOCam) performance in an environment that mimicked the temperatures and pressures of deep space were assessed by the test. NEOCam will be the key instrument for a proposed new asteroid-hunting space-based telescope for which design and capability details have...

President Barack Obama's NASA Budget Proposal Welcomed By UA Asteroid Experts
2013-04-11 08:10:17

University of Arizona Scientists at the University of Arizona welcome President Barack Obama's NASA budget proposal, rolled out today, and specifically its focus on gaining a better understanding of asteroids that could potentially harm Earth. The UA has a unique depth of capabilities and expertise that can help inform such missions and ensure their success. The UA is operating the most prolific ground-based system for identifying near-Earth asteroids, and it is tasked by NASA with...

Kappa Coronae Borealis
2013-04-10 05:00:44

Lee Rannals for redOrbit.com - Your Universe Online The European Space Agency's (ESA) Herschel space observatory has snapped images of a dust belt orbiting a subgiant star that hosts a planetary system. The space observatory's sensitive far-infrared detection helped astronomers resolve bright emission around Kappa Coronae Borealis, indicating the presence of a dusty debris disc. The star is a little heavier than our own Sun at 1.5 solar masses, is around 2.5 billion years old, and sits...

JAXA Set To Launch Hayabusa 2 In 2014
2013-04-01 20:59:22

Lee Rannals for redOrbit.com — Your Universe Online The Japan Aerospace Exploration Agency's (JAXA) next asteroid exploring spacecraft, Hayabusa 2, will be launching in 2014 on a mission to bring back sand from an asteroid. Hayabusa 2 will travel through space for four years before arriving at asteroid 1999 JU3, and will not be returning to Earth until 2020. Once the spacecraft reaches its target, it will fire off fingertip-sized bullets into the surface of the asteroid at about...

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...
