Aliens!! Rat bomb sniffers! Sugar beets! Evil cuteness!

It must be aliens or a super secret spy mission for Bond. James Bond:

LOS ANGELES — The U.S. military's secretive X-37B unmanned spaceplane slipped out of orbit and landed itself in early morning darkness Friday at a California airbase after a successful maiden flight that lasted more than seven months, the Air Force said.

And then there's the rodents...

Reporting from Bogota, Colombia — Rats may soon become heroic figures in this nation's struggle to detect and dispose of land mines.

Early next year, anti-narcotics police will begin deploying squads of rats to sniff out land mines in remote areas of Colombia where leftist rebels and drug traffickers have planted hundreds of thousands of the deadly devices. It's an unconventional initiative in a country that is second only to Afghanistan in the number of land mine victims.

Using a project in Tanzania as a model, Colombian scientists have taught rats to detect mines buried as deep as 3 feet. The rats are conditioned to search and burrow down for explosives in exchange for the reward of sugar.

Monsanto!

DES MOINES, Iowa – A federal judge in California has ordered the removal from the ground of plants grown to produce seeds for genetically modified sugar beets, citing the potential for environmental harm.

The ruling by U.S. District Judge Jeffrey White has again raised questions about the use of genetically modified crops and what will happen if growers aren't allowed to plant GMO seeds.

About 95 percent of the sugar beet crop has been genetically modified to resist the weed killer Roundup. The crop provides roughly half of the nation's sugar supply.
In his decision, White cited, "a significant risk of environmental harm."

Dangerous cute animals like the platypus. Be afraid!

Probably?? After all that money, probably?

WASHINGTON - A Navy missile soaring 130 miles above the Pacific smashed a dying and potentially deadly U.S. spy satellite Wednesday and probably destroyed a tank carrying 1,000 pounds of toxic fuel, officials said.

I still say they launched a faulty satellite filled with explosives so they could 'lose control' over it and then pretend to shoot it down to shock and awe the Chinese who did this last year.

The sad thing is.. we can't trust anything Bush and his cohorts say or do. So if we shot down a satellite, I'll wait until somebody else in some other country with some other satellite photos verifies it.

Update 2/22: Bryan of Why Now? says it better.

Watching the spy satellite come down

Keeping track of it as its orbit decays:

When and where will it hit the Earth ?
This is the question which interests most people, and unfortunately very difficult to answer. The satellite is being slowed down by friction with the tenuous upper atmosphere and losing height steadily, as can be seen in the plot below, which shows the orbital height over the last year. As it sinks further, the atmospheric density increases and so does the friction, making the descent faster and faster. Re-entry will happen when the height reaches about 100km.

What are the risks ?

Fortunately, the risk to people on the ground is extremely low. The Earth is large and two-thirds of it is covered by ocean. Most of the satellite will burn up in the upper atmosphere, but a few large pieces are expected to survive the re-entry and fall to Earth. It would be very unlikely for any of them to hit someone.

Where is USA 193 now ?

You can see the current position in the ground track below.

Can we take bets?

Hit or miss?

The Pentagon says it has to shoot down a malfunctioning spy satellite because of the threat of a toxic gas cloud. Space security experts are calling the rationale highly unlikely. "Having the US government spend millions of dollars to destroy a billion-dollar failure to save zero lives is comedic gold," one tells DANGER ROOM.

Yesterday, Deputy National Security Advisor James Jeffrey said the satellite's tank full of hydrazine rocket propellant was the main reason the military was planning to blast the orbiter. There's a small but real risk that the hydrazine tank could rupture, releasing a "toxic gas" over a "populated area," causing a "risk to human life."

But, as we noted yesterday, Joint Chiefs of Staff Vice Chairman Gen. James Cartwright cast the threat from the satellite in much less dire terms. Even if the hydrazine were released, he noted, the effects would likely be mild -- akin to chlorine gas poisoning, which can cause burning in the lungs, and elsewhere. The area affected would be "roughly the size of two football fields [where you might] incur something that would make you go to the doctor."

And that doesn't sound like much of a risk at all.

Especially when you consider that several other hydrazine-filled object have come crashing down to Earth. Not only did the space shuttle Columbia have a similar tank, which survived re-entry, with no toxic gas cloud. Several other hydrazine-laced objects have also crashed into the atmosphere, with no ill effects. Space researcher Ed Kyle notes that there were 42 major reentry objects for 2007, including 9 satellites -- at least one of which contained a form of hydrazine, UMDH (unsymmetrical dimethylhydrazine).

Hmmm... I wonder if they have an explosive already on board the satellite so they can claim they shot it down even though they will miss by a mile. That will show the Chinese!

Obviously, I bet they'll miss. And will lie about it.

Update 2/17. Now the Russians are involved:

Moscow, Russia (AHN) - Russia has accused the United States of testing an anti-satellite weapon system as the Pentagon prepares to shoots down a broken spy satellite.

The pentagon has not given enough reasons to support its plan of smashing down the satellite.

"There is an impression that the United States is trying to use the accident with its satellite to test its national anti-missile defense system's capability to destroy other countries' satellites," Russia's Defense Ministry said in a statement, according to the Associated Press.

According to a report, spy satellite USA 193 should be visible in sky around the southeastern horizon before it is destroyed.

Update 1/17 11:30pm:

Jeffery of Arms Control Wonk:

Holding the aside the politics of this — which are terrible — the briefing on debris risk left me cold. I have to say that I am very, very uneasy about this decision — our missile defense tests have been heavily scripted to minimize debris creation and modeling of debris creation isn’t an exact science.

[snip]

1. The intercept will occur at 240 kilometers (130 nautical miles)
2. The mass of the satellite is 2,300 kg (5,000 pounds)
3. The mass of the interceptor is 20 kg. (From CBO)
4. The closing velocity will be 9.8 km/s (22,000 mph), suggesting a virtually head-on collision.

Other pertinent observations. At 240 km, the satellite should be traveling 7.8 km/s; the SM-3 has a burnout velocity of 3 km/s.

I am very worried about the debris creation — particularly the debris that the light-weight interceptor will kick into higher orbits when it hits the massive (bus-sized) satellite. Thnk, as Geoff Forden suggested, of a ping pong ball hitting a superball.

Virtually all the debris should come down quickly. Cartwright said 50 percent would come down within two orbits, with the rest coming down in weeks and months. That seems plausible, at first blush.

But those two orbits could be hairy and some of the debris will remain in orbit. Michael Griffin, NASA Administrator, said there are “good times and bad times” to conduct the intercept, based on the position of the ISS but that “bad times are not all that bad” comparing the risk to an order of magnitude lower than flying the shuttle.

Last I checked, the PRAN for the shuttle was 1 in 100. Extrapolating, there would be only a 1 in 1000 chance of wiping out the ISS.

Keep the car gassed up and buy a hard hat...

Duct tape and plastic wrap won't save you now:

WASHINGTON (AP) -- A large U.S. spy satellite has lost power and propulsion and could hit the Earth in late February or March, government officials said Saturday.

The satellite, which no longer can be controlled, could contain hazardous materials, and it is unknown where on the planet it might come down, they said.

The officials spoke on condition of anonymity because the information is classified as secret.

"Appropriate government agencies are monitoring the situation," said Gordon Johndroe, a spokesman for the National Security Council.

"Numerous satellites over the years have come out of orbit and fallen harmlessly. We are looking at potential options to mitigate any possible damage this satellite may cause."

Ahem. Just WHY is this classified as secret? On a need to know basis? Like ... your house may be flattened by a burning radioactive object hurtling through earth's atmosphere .. but go shopping.

Appropriate government agencies? Have they been Busherized? Do they still have scientists and mathematicians who can calculate orbital fall? Or are they just going to go down in the White House bunkers and other undisclosed locations and sit this one out?

Appropriate government agencies, my ass.
