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...

Targeting An Asteroid
2013-04-17 10:28:38

NASA's Jet Propulsion Laboratory Like many of his colleagues at NASA's Jet Propulsion Laboratory, Pasadena, Calif., Shyam Bhaskaran is working a lot with asteroids these days. And also like many of his colleagues, the deep space navigator devotes a great deal of time to crafting, and contemplating, computer-generated 3-D models of these intriguing nomads of the solar system. But while many of his coworkers are calculating asteroids' past, present and future locations in the cosmos,...

Well, if it wasn't for the vacuum in space, then we would hypothetically be getting that rush as asteroid 2012 DA14 makes its nail-biting, close-approach of Earth this...

OSIRIS-Rex To Study Asteroid Yarkovsky Effect
2013-02-08 18:46:31

Lee Rannals for redOrbit.com — Your Universe Online NASA will be launching a new mission in 2016 to help estimate what kind of impact an asteroid would make if it struck Earth. The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, and Regolith Explorer) mission will travel to a potentially hazardous asteroid (PHA), and make measurements of the Yarkovsky effect. This effect is a push on an asteroid that happens when it is warmed up by the sun and...

Massive Asteroid Will Not Strike Earth In 2040
2012-12-23 05:40:35

redOrbit Staff & Wire Reports - Your Universe Online A 140 meter diameter asteroid experts once believed had a one in 500 chance of striking the earth no longer presents a significant impact risk, NASA officials have confirmed. Previously, orbital uncertainties meant there could have been a 0.2-percent chance that asteroid 2011 AG5 would collide with the planet in February 2040, prompting the scientific community -- including David Tholen, Richard Wainscoat and Marco Micheli of the...

Radar Images Of Asteroid 2007 PA8
2012-11-27 20:02:52

NASA Jet Propulsion Laboratory A collage shows nine radar images of near-Earth asteroid 2007 PA8 that were obtained between Oct. 31 and Nov. 13, 2012, with data collected by NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif. On Nov. 5 at 8:42 a.m. PST (11:42 a.m. EST/16:42 UTC), the object came about 4 million miles (6.5 million kilometers) from Earth, or 17 times the distance between Earth and the moon. The images of 2007 PA8 reveal possible craters,...

Asteroid Imaged By Deep Space Network Antenna
2012-11-06 06:27:07

NASA Statement Scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have obtained several radar images depicting near-Earth asteroid 2007 PA8. The images were generated from data collected at Goldstone on Oct. 28, 29 and 30, 2012. The asteroid's distance from Earth on Oct. 28 was 6.5 million miles (10 million kilometers). The asteroid's distance to Earth was 5.6 million miles (9 million kilometers) on Oct. 30. The perspective in the...

Asteroid Needs A Name!
