Asteroid threat has Congress' attention

As if you don't have enough to worry about, consider the subject of a hearing last week on Capitol Hill: asteroids that may be headed toward Earth. The good news: NASA is tracking most of the largest asteroids - the kind that a witness said "would likely end civilization" were they to hit.

"None of these civilization-enders thus far discovered is known to be on an impact course any time in this upcoming century," Ed Lu, a former astronaut who heads a group working to launch a to track threatening asteroids, told the House Space, Science and Technology Committee.

But there may be a lot of potential "city destroyers" up there that have yet to be detected.

" has not even come close to finding and tracking the 1 million smaller asteroids that might only wipe out a city," Lu said. "We can protect the Earth from impacts, but we can't do it if we don't know where the asteroids are."

The hearing Wednesday was the third on space threats since a 60-foot asteroid exploded over Russia in February, injuring about 1,500 people and causing millions of dollars in damage. On the same day, a 150-foot asteroid passed within 17,200 miles of Earth.

President has sent to Congress a proposed budget that includes funding to help NASA step up its efforts to identify space threats, as well as money to send an astronaut to an asteroid by 2025.

committee Chairman Lamar Smith, R-Texas, holding up a small piece of the asteroid that exploded over Russia, called it troubling that scientists had identified only 10 percent of the asteroids that could potentially destroy a city.

The asteroid explosion over Russia and the close flyby on the same day "demonstrate that even extremely improbable events can happen, and that it is prudent to pay attention to the problem of finding and tracking all potentially hazardous near-Earth asteroids," Donald K. Yeomans, manager of NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory, said in his written testimony.

Yeomans noted that a spacecraft could ram an asteroid, "modifying its orbital velocity by a very small amount, so that over several years its trajectory would be modified and its predicted impact of Earth in the future avoided by a safe margin."

NASA officials are worried that tighter budgets could delay its work.

News to me, didn't know they had a plan in place yet to protect us.

They have been more worried about global warming in 100 years.

funny , a nice little light show exploded over spain today. yea, asteroids are hitting earth ALL the time, it's the big ones that are not, and the ones to be worried about that. between the big asteroids and the big solar storms, that's about 2 major things you can prepare civilization for and defend against.

please please, no nonsense about man made climate change in the comments. neither of those poses anywhere near the outsize threat of catching civilization fully off guard with the threat of a surprise catastrophic destruction; no matter what you see in the movies, climate change is not going to snap on us in just a few day the way a solar storm could, or as instantaneous as a massive asteroid strike and the ensuing winter that would result from all the dust being aerosolized into the atmosphere.

Also, I don't know if it's just that we have only recently been able to observe it but it seems an usually large number of rocks are coming close to us, Apophis and 2 others, and little events like Chelyabinsk.

I for one would love to pursue a means of establishing multiple scientific/construction colonies. Lot's of desolate moons around Saturn and Jupiter.

Note, your comment itself could be construed as "nonsense about man made climate change". Or maybe you'd like to share some CV to help convince the rest of us you can be a respected source of knowledge. That you understand how to determine risk. That you aren't subject to bias that might cause you to make incorrect assessments.

We should treat it like typical problem on this forum and divide in to three groups:
1) Group A would deny existence of any rogue asteroids and claim world wide fraud
2) Group B would blow this problem out of any proportion and claim being the group supported by scientific consensus
3) Group C would claim that the problem can be solved using cold fusion

The really scary objects aren't the NEO's. Objects falling from the Kuiper belt, Ort cloud, or interstellar space are much more dangerous. They tend to be much larger, there are more of them, and they are moving 100's of times faster as they go past Earth. They are also much harder to see and come with too little warning time to do much, if anything, about. An object headed towards us from a direction not in line with the ecliptic from the Oort cloud would very likely be impossible to intercept with current technology. There are many trajectories that we could not achieve in time, even if we knew about the threat.

More small ones Asteroids to Impact

Father like son both Archimedes and his Father Phidias the Astronomer were well know to all wise men of their day that studied the Heavens Above. Long ago Wicked men dried to wipe out Archimedes and his Father Phidias from the History Books.

More small ones very likely large ones less likely without notice with all the eyes looking to the Heavens Above.

The PLANETARY DEFENSE is not to protect Earth from men from Mars.
It is for all mankind with most all Nation in on it to stop if can most all collision with EARTH from a ASTEROID IMPACT. It is if you will a AVOIDANCE SHIELD. "N.E.O.S. Near Earth Object Shield".

If only one were to hit or IMPACT EARTH on land get ready for a winter you will never forget. The winter from 1883 -1884 KRAKATOA you will think was a little pebble, and now the stone comes. Krakatoa was a great mountain till it erupted with fire and a blast heard thousands of miles away that cast that Great Mountain into the sea. The Shock Waves were felt around the Globe. The sea was full of Bodies from the Tsunamis more then 35,000 of them, the sea stayed red for weeks. 1884 was a year without a summer as the year 1816 was and many world wide Froze to Death from the KRAKATOA Event.

A Shock Wave was felt in England from a Event about 7:15 to 7:20 A.M. Siberia time in the morning in June of the year 1908 high in the sky above the Forest in the remote wilderness of Tunguska Siberia heard an explosion that laid flat more than 800 square miles of the forest with all the trees pointing away from the center of the blast with most all the trees laying on their side. Some trees that were right below the blast were still there looking like telephone poles with no bark or branches left on them. This Asteroid did not even hit the Ground and this is known by most as the TUNGUSKA EVENT. For all that lived there it was WORMWOOD Rev 8:11 the wood became full of worms and the rivers water no longer sweet and undrinkable.

If a Meteor Shower is big enough you might think all the Stars are falling from Heaven.



About one every 100 years makes it into the Earth's Atmosphere big enough for all to take note. Some make it to the surface the signs are all over the Planet and moon from the ones that have.



If you need a visual sign of a collided impact with a planet look to

"SHOEMAKER - LEVY 9" July 1994.

and it was found only a year before in 1993.
The impacts lasted for hours and some pieces were over a mile in diameter.



You Need More Look up "PROJECT WORMWOOD" Revelations 8: 10 - 11 based on the "TUNGUSKA EVENT" 1908

MOSCOW Russia is now saying it will use missiles to intercept Asteroid if need be.



Better to be safe then sorry.

The day will come when

ALL ON EARTH WILL SEE THIS NO MATTER WHERE YOU ARE. the night side of earth will become day and and day will be blinding bright. The Bow Shock from the Photo Electric Effect from the Sun's Solar Wind will really be something.

Shortly there after you will think the stars are falling from the Heavens,
REV 6:13,
REV 16:21
most will be between 60 to 80 pounds that will make it to the ground surface. Nonstop 12 to 14 hours at a time for two days.

P.S.
Help others in are Lord's name Jesus Christ help bring all to know him while you still can.Three kings that were wise men once flowed a star with a long tail 2,000 years ago. That lead them to Jesus Christ wise men still look to and hear are Lord Jesus Christ.
