Nasa‘s advice on asteroid hitting Earth: pray

Charles Bolden, the chief of the Nasa, has warned that the US space agency’s best advice on how to handle a large asteroid heading towards New York City is “pray”.

Mr Bolden told US lawmakers that prayer was all that the US or anyone could currently do about unknown asteroids and meteors that may be on a collision course with Earth.
An asteroid estimated to be have been about 55 feet (17 metres) in diameter exploded on Feb 15 over Chelyabinsk, Russia, generating shock waves that shattered windows and damaged buildings. More than 1,500 people were injured.
Later that day, a larger, unrelated asteroid discovered last year passed about 17,200 miles (27,681 km) from Earth, closer than the network of television and weather satellites that ring the planet.
The events “serve as evidence that we live in an active solar system with potentially hazardous objects passing through our neighborhood with surprising frequency,” said Representative Eddie Bernice Johnson, a Texas Democrat.
“We were fortunate that the events of last month were simply an interesting coincidence rather than a catastrophe,” said US House of Representatives Science Committee chairman Lamar Smith, a Texas Republican.
Mr Smith called a hearing on Tuesday to learn what is being done and how much money is needed to better protect the planet.
Nasa has found and is tracking about 95 percent of the largest objects flying near Earth, those that are .62 miles (1 km) or larger in diameter.
“An asteroid of that size, a kilometer or bigger, could plausibly end civilization,” White House science advisor John Holdren told legislators at the same hearing.
But only about 10 percent of an estimated 10,000 potential “city-killer” asteroids, those with a diameterof about 165 feet (50 meters) have been found, Mr Holdren added.

On average, objects of that size are estimated to hit Earth about once every 1,000 years.
“From the information we have, we don’t know of an asteroid that will threaten the population of the United States,” Mr Bolden said. “But if it’s coming in three weeks, pray.”
In addition to stepping up its monitoring efforts and building international partnerships, Nasa is looking at developing technologies to divert an object that may be on a collision course with Earth.
“The odds of a near-Earth object strike causing massive casualties and destruction of infrastructure are very small, but the potential consequences of such an event are so large it makes sense to takes the risk seriously,” Mr Holdren said.


About 66 million years ago, an object 6 miles (10 km) in diameter is believed to have smashed into what is now the Yucatan Peninsula in Mexico, leading to the demise of the dinosaurs, as well as most plant and animal life on Earth.
The asteroid that exploded over Russia last month was the largest object to hit Earth’s atmosphere since the 1908 Tunguska event when an asteroid or comet exploded over Siberia, leveling 80 million trees over more than 830 square miles (2,150 sq km).

The rancher and a Skippy minion

A cowboy named Bob was overseeing his herd in a remote mountainous pasture in Montana when suddenly a brand-new BMW advanced toward him out of a cloud of dust.

The driver, a young man in a Brioni® suit, Gucci® shoes, RayBan® sunglasses and YSL® tie, leaned out the window and asked the cowboy, “If I tell you exactly how many cows and calves you have in your herd, will you give me a calf?”
Bob looks at the man, who obviously is a yuppie, then looks at his peacefully grazing herd and calmly answers, “Sure, why not?”

The yuppie parks his car, whips out his Dell® notebook computer, connects it to his Cingular RAZR V3® cell phone, and surfs to a NASA page onthe Internet, where he calls up a GPS satellite to get an exact fix on his location which he then feeds to another NASA satellite that scans the area in an ultra-high-resolution photo.

The young man then opens the digital photo in Adobe Photoshop® and exports it to an image processing facility in Hamburg, Germany
Within seconds, he receives an email on his Palm Pilot® that the image has been processed and the data stored. He then accesses an MS-SQL® database through an ODBC connected Excel® spreadsheet with email on his Blackberry® and, after a few minutes, receives a response.

Finally, he prints out a full-color, 150-page report on his hi-tech, miniaturized HP LaserJet® printer, turns to the cowboy and says, “You have exactly 1,586 cows and calves.”

“That’s right. Well, I guess you can take one of my calves,” says Bob.
He watches the young man select one of the animals and looks on with amusement as the young man stuffs it into the trunk of his car.

Then Bob says to the young man, “Hey, if I can tell you exactly what your business is, will you give me back my calf?”

The young man thinks about it for a second and then says, “Okay, why not?”
“You’re a Congressman for the U.S. Government”, says Bob.
“Wow! That’s correct,” says the yuppie, “but how did you guess that?”
“No guessing required.” answered the cowboy. “You showed up here even though nobody called you; you want to get paid for an answer I already knew, to a question I never asked. You used millions of dollars worth of equipment trying to show me how much smarter than me you are; and you don’t know a thing about how working people make a living – or about cows, for that matter. This is a herd of sheep.

Now give me back my dog.
AND THAT FOLKS IS WHAT THE PROBLEM IS ALL ABOUT.

The Asteroid that Whisked by Earth

Did you feel it?

That huge asteroid that got conspiracy kooks all atwitter, such as Richard Hoagland who hysterically claimed that the asteroid would “smash” into the Moon on Nov. 9, 2011 — today.

Well, asteroid 2005 YU55 did whisk by Earth, nor did it smash into the Moon.

Here are some radar images of the asteroid from Space.com. The pics were taken on Nov. 7, 2011, at 11:45 a.m. PST (2:45 p.m. EST/1945 UTC), when the space rock was at 3.6 lunar distances, which is about 860,000 miles from Earth.

Did you see how the asteroid “smashed” into the Moon? LOL

We can now go on to the next apocalyptic event.

Today, Nov. 9, 2011, at 2 p.m., EST, FEMA and the FCC will conduct America’s first ever Emergency Alert System test. The test is “to assess the readiness and effectiveness of the current system and identify incremental improvements to better serve our communities in the preservation of life and property,” according to the FEMA website.

This is similar to the brief, but annoying, Emergency Alert System tests you hear on radio.

But this one is different, because it’s not just radio, but television this time. “All local, cable, and satellite TV stations across the country, as well as radio,” will be involved in the test, which will last “approximately three minutes.”

Which means that for the duration of  a pop song, every household, car and business in America–except for NOAA weather radio—will be pulsing, squawking, hissing and whistling a test message that begins with the ominous phrase, “This is a test.”

I suggest Hoagland, et al, should worry about this asteroid instead:

NASA: UARS Could Still Hit US


Last week, I posted about a used-up climate probe satellite known as UARS that NASA expected was going to reenter the Earth’s atmosphere sometime around today.

It appears its descent has now slowed somewhat, and may not come down until later tonight or possibly sometime tomorrow, which is when NASA had once thought was the most likely date of its return.

NASA is also saying that there is a chance it could come down somewhere here in America, although they are still not sure exactly where it will fall.

Of course, given this satellite’s mission, I’m still pulling for the roof of Al Gore’s mansion.  ;-)

As a hopeless space junkie, I have seen meteors streak across the sky many times, but I have never seen something man-made and the size of a school bus reenter the atmosphere live and in person.

That would be really cool to see.

Earth to satellite: When will you hit — and where?

By MARCIA DUNN – AP Aerospace Writer | AP – 11 hrs ago

I don’t know about you but 1 in 3200 is not that bad. You have a better chance of getting hit with space junk than the lottery or getting struck by lightning.

CAPE CANAVERAL, Florida (AP) — NASA scientists are doing their best to tell us where a plummeting six-ton satellite will fall later this week. It’s just that if they’re off a little bit, it could mean the difference between hitting Florida or landing on New York. Or, say, Iran or India.

Pinpointing where and when hurtling space debris will strike is an imprecise science. For now, scientists predict the earliest it will hit is Thursday U.S. time, the latest Saturday. The strike zone covers most of Earth.

Not that citizens need to take cover. The satellite will break into pieces, and NASA put the chances that somebody somewhere will get hurt at just 1-in-3,200.

As far as anyone knows, falling space debris has never injured anyone. Nor has significant property damage been reported. That’s because most of the planet is covered in water and there are vast regions of empty land.

If you do come across what you suspect is a satellite piece, NASA doesn’t want you to pick it up. The space agency says there are no toxic chemicals present, but there could be sharp edges. Also, it’s government property. It’s against the law to keep it as a souvenir or sell it on eBay. NASA’s advice is to report it to the police.

What Goes Up Must (Eventually) Come Down

 

Mir reentry March 2001
NASA satellite UARS, launched in 1991 and deactivaed in 2005,  is expected to reenter Earth’s atmosphere on or about the 23rd of this month.

A satellite reentry is not usually big news, and this one really is not either, other than perhaps its large size, which is said to be about that of a school bus.

What caught my eye when reading the Space.com article linked above was NASA’s explanation as to what had degraded its orbit:

NASA spokeswoman Beth Dickey confirmed with SPACE.com earlier today that the reason UARS is expected to fall early in its re-entry window is because of the sharp uptick in solar activity. Solar effects from the sun can create an extra drag on satellites in space because they can heat the Earth’s atmosphere, causing it to expand, agency officials have said.

LOL – But hasn’t James Hansen and his crew of NASA “scientists” been telling us all along that it was our SUVs and light bulbs that were warming Earth’s atmosphere?

There is one further tidbit of interesting, if not a little ironic information concerning UARS:

It is a climate probe satellite that was launched during the ozone scare.

A Tale of Three Galaxies

In April 2009, NASA’s Hubble telescope’s Wide Field Planetary Camera took this image of Arp 274 — a system of three galaxies that appear to be partially overlapping in the image, although they may be at somewhat different distances. The spiral shapes of two of these galaxies appear mostly intact. The third galaxy (to the far left) is more compact, but shows evidence of star formation.

Two of the three galaxies are forming new stars at a high rate. This is evident in the bright blue knots of star formation that are strung along the arms of the galaxy on the right and along the small galaxy on the left.

The largest component is located in the middle of the three. It appears as a spiral galaxy, which may be barred. The entire system resides at about 400 million light-years away from Earth in the constellation Virgo.

The colors in this image reflect the intrinsic color of the different stellar populations that make up the galaxies. Yellowish older stars can be seen in the central bulge of each galaxy. A bright central cluster of stars pinpoint each nucleus. Younger blue stars trace the spiral arms, along with pinkish nebulae that are illuminated by new star formation. Interstellar dust is silhouetted against the starry population. A pair of foreground stars inside our own Milky Way are at far right.

Texas Ablaze

This is the view of the terrible wildfires sweeping Texas, as seen from the International Space Station.

Beginning a week ago, blustering wind whipped up by Tropical Storm Lee swept across parched, drought-stricken Texas, sparking more than 190 wildfires. The worst of the fires has consumed more than 34,000 acres 30 miles southeast of Austin.

The number of homes destroyed has risen to 1,554 and is expected to further increase as firefighters enter more areas where the blaze has been extinguished, officials said Sunday. Seventeen people remain unaccounted for.

It’s difficult for most folks to really understand the scope of the crisis. Texas has suffered from a significant lack of rain all summer; 81% of the state’s land is listed as “exceptional drought” on the U.S. Drought Monitor’s scale. That makes conditions perfect for a terrifying blaze.

The video taken by the International Space Station helps us to better understand the scope. You can clearly make out the smoke plumes where they rise above Texas. The size of these fires is just that much more mind-boggling when you consider how visible they are from space.

Mercy, God! Have mercy on the innocent suffering wildlife and the humans who were made in your image….

That’s Some Cloud!

A roll cloud extends far into the distance as a storm approached in 2007 in Racine, Wisconsin:

Image Credit: Pierre cb, Wikipedia

Explanation: What kind of cloud is this? A type of arcus cloud called a roll cloud. These rare long clouds may form near advancing cold fronts. In particular, a downdraft from an advancing storm front can cause moist warm air to rise, cool below its dew point, and so form a cloud. When this happens uniformly along an extended front, a roll cloud may form. Roll clouds may actually have air circulating along the long horizontal axis of the cloud. A roll cloud is not thought to be able to morph into a tornado. Unlike a similar shelf cloud, a roll cloud is completely detached from their parent cumulonimbus cloud.

Black Hole Devours Star

Disclaimer:

Neither this post’s title nor its subject is a racist insult, although truth be told, there really is a black hole occupying the White House because it is sucking the life out of America.

A black hole is a region of spacetime from which nothing, not even light, can escape. It is called “black” because it absorbs all the light that hits the horizon, reflecting nothing. Around a black hole there is a mathematically defined surface called an event horizon that marks the point of no return.

Black holes of stellar mass are expected to form when heavy stars collapse in a supernova at the end of their life cycle. After a black hole has formed it can continue to grow by absorbing mass from its surroundings. By absorbing other stars and merging with other black holes, supermassive black holes of millions of solar masses may be formed.

Despite its invisible interior, the presence of a black hole can be inferred through its interaction with other matter. There is growing consensus that supermassive black holes exist in the centers of most galaxies. In particular, there is strong evidence of a black hole of more than 4 million solar masses at the center of our Milky Way.

Black hole eats star

Last March, NASA’s Swift spacecraft first detected what scientists believe to be a black hole eating a star 3.8 billion light years from earth. By devouring the star, the black hole not only sent a beam of X-rays shooting towards Earth, it also “rejuvenated” itself.

Here’s a video NASA put together, imagining the event:

NASA’s Goddard Space Flight Center explains why matter and X-rays are shooting out of the black hole:

“As a star falls toward a black hole, it is ripped apart by intense tides. The gas is corralled into a disk that swirls around the black hole and becomes rapidly heated to temperatures of millions of degrees.

The black hole itself is enormous, potentially four times the size of the one at the center of the Milky Way, according to NASA. The massive hole also seems to be shooting matter out of its center at 80 to 90% of the speed of light.

An event like this has never before been seen by scientists. David Burrows, professor of astronomy at Penn State University, told NASA, “It behaves unlike anything we’ve seen before.”

Earlier this year, NASA reported that the Swift telescope had detected dual black holes, that is, a supermassive blackhole at the center of a galaxy located extremely close to another galaxy with a blackhole at its center–a rarely observed occurrence.

At the 2011 Ted conference, Janna Levin, a professor of physics and astronomy at Barnard College, described the “sound” of a black hole as like “someone knocking on the door, or mallets banging on a drum.”
