That is good news! Thanx John:) Kinda losing hope in an Orbit@home restart. Looks like they're still online though:

I know what you mean Julie. Month after month goes by and no word is spoken. No updates ... nothing.

Just stumbled upon a relatively new NASA asteroid detection project ATLAS: Asteroid Terrestrial-Impact Last Alert System.

It is a ground based network of 8 small telescopic cameras with up to 100 megapixel resolution. It should provide a seven day warning of a 45 meter city killer rock. You can read more about it here: [url]www.space.com/19864-asteroid-threat-atlas-warning-system.html[\url]

Thanks John.

NASA not looking out for asteroids, not good. Happy others are watching.

NASA Announces Next Steps on Journey to Mars: Progress on Asteroid Initiative

NASA Wednesday announced more details in its plan for its Asteroid Redirect Mission (ARM), which in the mid-2020s will test a number of new capabilities needed for future human expeditions to deep space, including to Mars. NASA also announced it has increased the detection of near-Earth asteroids by 65 percent since launching its asteroid initiative three years ago.

For ARM, a robotic spacecraft will capture a boulder from the surface of a near-Earth asteroid and move it into a stable orbit around the moon for exploration by astronauts, all in support of advancing the nation’s journey to Mars.

Kinda late posting this.

Asteroid to Pass 6 Million Miles from Earth Thursday

An asteroid, designated 1999 FN53, will safely pass more than 26 times the distance of Earth to the moon on May 14. To put it another way, at its closest point, the asteroid will get no closer than 6.3 million miles away (10 million kilometers). It will not get closer than that for well over 100 years. And even then, (119 years from now) it will be so far away it will not affect our planet in any way, shape or form. 1999 FN53 is approximately 3,000 feet (1 kilometer) across.

"This is a flyby in the loosest sense of the term," said Paul Chodas, manager of NASA's Near-Earth Object Program Office, at the Jet Propulsion Laboratory in Pasadena, California. "We can compute the motion of this asteroid for the next 3,000 years and it will never be a threat to Earth. This is a relatively unremarkable asteroid, and its distant flyby of Earth tomorrow is equally unremarkable."

Asteroid Icarus to skim past the Earth in rare 'distant pass'



Asteroid Icarus, the kilometre-long spacerock named after the Greek mythological character that flew too close to the sun, will skim past the Earth on Tuesday night making a rare “distant pass” of five million miles.

According to Nasa, the asteroid 1566 Icarus will safely pass by the Earth at more than 21 lunar distances, which is 21 times the distance between form the Earth to the moon.

Can't make this stuff up.

Asteroid tsunami could kill thousands in Britain, warn scientists
Although the UK is not directly in an asteroid path, it is at risk from impact 'corridors' of known asteroids in the Atlantic Ocean and North Sea which could trigger devastating tsunamis

Britain is at risk from an asteroid tsunami which could kill hundreds of thousands of people living in coastal regions, scientists have warned.

Experts at the University of Southampton have developed software which predicts the impact ‘corridors’ of known asteroids and calculates the risk to communities if they struck.

Although the UK is not directly under an asteroid path, it is at risk from impacts in the Atlantic Ocean and North Sea which could trigger devastating tsunamis. For example there is a one in 10,000 chance that a space rock could hit just off the coast of Norfolk within the next 85 years.

we don't have ANY confirmed HITS on Torino scale...so NO! None of the Asteroids is going to hit us, soon!

I really don't understand the north/south tracks of probable impact - if a track is running north south where the impact is will depend on the time of day, not some "mystical" bent line on a map. Likewise the "east/West" tracks should continue right round the globe, as again the impact location will be dependent upon time of impact....
Very poor "science" and equally as bad journalism, what a combination for getting the wrong end of a story...


(That said the UK has a number of locations that are vulnerable to being hit by Tsunami in the event of earthquakes or volcanic activity in the North Atlantic region)

The new maps show a wide asteroid risk zone running through Europe, passing directly over Scandanavia, Germany, France and Spain.

Scandinavia?
According to the map Scandinavia has a "low" risk. British Isles and Russia as well.

PhD student Clemens Rumpf
“We have discovered around 13,000 asteroids and around 500 of them have a chance of hitting Earth,”
Only 13,000?
There are about 19,000 asteroids found and even have a name.
Many more without a name.
Actually one asteroid has my surname:)
Nr 18016 http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=18016
Discovered 1999 May 13 by the Lincoln Laboratory Near-Earth Asteroid Research Team at Socorro.

Currently there are about 19044 asteroids named officially by the IAU (International Astronomical Union).

In the news..

NASA: There is No Asteroid Threatening Earth

Numerous recent blogs and web postings are erroneously claiming that an asteroid will impact Earth, sometime between Sept. 15 and 28, 2015. On one of those dates, as rumors go, there will be an impact -- "evidently" near Puerto Rico -- causing wanton destruction to the Atlantic and Gulf coasts of the United States and Mexico, as well as Central and South America.
