Collage Of Radar Images Of Asteroid 2005 WK4
2013-08-16 17:04:11

NASA A collage of radar images of near-Earth asteroid 2005 WK4 was generated by NASA scientists using the 230-foot (70-meter) Deep Space Network antenna at Goldstone, Calif., on Aug. 8, 2013. The asteroid is between 660 and 980 feet (200 and 300 meters) in diameter; it has a rounded and slightly asymmetric shape. As it rotates, a number of features are evident that suggest the presence of some flat regions and a bulge near the equator. The data were obtained between 12:40 and 7:10...

Asteroids Classified As Easily Retrievable Objects
2013-08-13 04:33:19

Enid Burns for redOrbit.com - Your Universe Online While disaster movies are made about the looming threat of asteroids colliding with the earth, scientists are studying the space rocks for their mineral potential. Now scientists at the University of Strathclyde in the UK have identified a new category of asteroid they deem easy to capture. Scientist Daniel Garcia Yarnoz and a few colleagues at the University of Strathclyde have studied a database of over 9,000 near-Earth objects, and...

Asteroid Initiative RFI Receives 400+ Responses
2013-07-27 07:19:30

April Flowers for redOrbit.com - Your Universe Online NASA Deputy Administrator Lori Garver announced this week that the agency has received more than 400 responses to its request for information (RFI) on its Asteroid Initiative. "Under our plan, we're increasing the identification, tracking and exploration of asteroids, and the response to this initiative has been gratifying," said Garver, speaking at the Space Frontier Foundation's NewSpace 2013 conference in San Jose, Calif. "The...

NASA's Jet Propulsion Laboratory For his work making the solar system's nomads of the night sky -- near-Earth objects, asteroids and comets -- tangible and compelling for millions of people, Donald K. Yeomans, the manager of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, has received the 2013 Carl Sagan Medal from the American Astronomical Society (AAS). The Sagan Medal recognizes a planetary scientist for excellence in public communication....

Hawaiian Telescope Discovers Ten Thousandth Near-Earth Object
2013-06-25 13:56:23

Lee Rannals for redOrbit.com – Your Universe Online NASA said the 10,000th near-Earth object (NEO) has been discovered using the Pan-STARRS-1 telescope in Hawaii. Astronomers spotted asteroid 2013 MZ5 on the night of June 18, marking a significant milestone for the NEO search. The space agency said 90 percent of all NEOs discovered were first detected by NASA-supported surveys. "But there are at least 10 times that many more to be found before we can be assured we will have found...

NEAR-Shoemaker Mission -- The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of Gene Shoemaker, is an unmanned spacecraft designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objectives of NEAR were to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith...

Near-Earth Object -- Near-Earth Objects (NEO) are asteroids, comets and large meteoroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger. Due to their size and proximity, NEO's are also more easily accessible for spacecraft from Earth and are important for future scientific investigation and commercial development. In fact, some near-Earth asteroids can be reached with much less ΔV (change in velocity) than the Moon. In the United States, NASA...

Near-Earth Asteroid -- Near-Earth asteroids (NEAs) are asteroids whose orbit intersects Earth's orbit and which may therefore pose a collision danger, as well as being most easily accessible for spacecraft from Earth. In fact, some near-Earth asteroids can be reached with much less ΔV than the Moon. The most famous near-Earth asteroid is 433 Eros that was visited by NASA's Near Earth Asteroid Rendezvous probe. A few hundred such near-Earth asteroids are known, ranging in size up...

433 Eros -- The asteroid 433 Eros was named after the Greek god of love Eros. It is an S-type asteroid approximately 13 x 13 x 33 km in size, the second-largest near-Earth asteroid. It was visited by the NEAR Shoemaker probe, which first orbited it taking extensive photographs of its surface and then in 2001 at the end of its mission was landed on the asteroid's surface using only its maneuvering jets. Depending on where they stood on Eros, a person who weighed 200 pounds (90...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
