Small Asteroid Will Pass By Earth Safely
2013-02-04 08:30:02

NASA's Jet Propulsion Laboratory The small near-Earth asteroid 2012 DA14 will pass very close to Earth on February 15, so close that it will pass inside the ring of geosynchronous weather and communications satellites. NASA's Near-Earth Object Program Office can accurately predict the asteroid's path with the observations obtained, and it is therefore known that there is no chance that the asteroid might be on a collision course with Earth. Nevertheless, the flyby will provide a unique...

Large Asteroid Will Make Earth Flyby Next Month
2013-01-29 12:55:40

[Watch Video: Record-Setting Asteroid Flyby] Lee Rannals for redOrbit.com — Your Universe Online A record-setting asteroid about the size of half a football field will be making a close flyby to Earth just after Valentine's Day. Although there is no danger of a collision, the asteroid, 2012 DA14, will still be making a record-setting close approach, according to NASA. "Since regular sky surveys began in the 1990s, we've never seen an object this big get so close to Earth," Don...

Apophis Won’t Hit Earth In 2036
2013-01-13 08:33:31

redOrbit Staff & Wire Reports — Your Universe Online There is a less than one-in-a-million chance that a massive asteroid, approximately as wide as three American football fields, will collide with Earth in 2036, NASA officials confirmed on Wednesday. According to MSNBC.com´s Alan Boyle, the “all-clear” was sounded by the US space agency after asteroid Apophis came within nine million miles of our planet. In fact, officials with NASA´s...

Herschel Observed Asteroid Apophis Over The Weekend
2013-01-09 14:28:25

ESA ESA´s Herschel space observatory made new observations of asteroid Apophis as it approached Earth this weekend. The data shows the asteroid to be bigger than first estimated, and less reflective. Catalogued as asteroid (99942) Apophis (previously 2004 MN4), it is often nicknamed ℠the doomsday asteroid´ in popular media, after initial observations made after its discovery in 2004 gave it a 2.7% chance of striking Earth in April 2029. With additional data, however,...

Asteroid Apophis To Swing By Earth This Week
2013-01-09 05:27:01

April Flowers for redOrbit.com - Your Universe Online Asteroid 99942, named Apophis after an ancient Egyptian mythological demon, will be whizzing by Earth this week. Apophis is a near-Earth asteroid with an estimated diameter of approximately three football fields — over 880 feet. The Slooh Space Camera will cover it's near approach on Wednesday, January 9th, 2013. The public can watch several live shows — available on PC, iPhone and Android devices - on Slooh.com starting...

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 Fragments May Give Insight Into Origins Of Planets
2012-10-05 13:38:38

Alan McStravick for redOrbit.com - Your Universe Online The year was 1998. The Red Hot Chili Peppers had just parted ways with Dave Navarro. The world was introduced to Britney Spears. And the movie Armageddon bested all other films at the box office. It seems fitting that the same year that gave us Michael Bay´s fictional interpretation of how we should deal with an asteroid coming towards us would be the same year that the Lincoln Near-Earth Asteroid Research (LINEAR) project...

Asteroid Needs A Name!
2012-09-04 13:39:18

Watch the Video: NASA Announces Asteroid Naming Contest Lee Rannals for redOrbit.com - Your Universe Online NASA is opening up an opportunity for students to help name an asteroid the space agency will be gathering samples from and returning back to Earth. The Origins-Spectral Interpretation-Resource Identification-Security-Regolith Explorer (OSIRIS-REx) mission is scheduled to launch in 2016. During the mission, a spacecraft will land on the near-earth asteroid currently called 1999...

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...

  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
