The Soviet Union’s gigantic nuclear equipped Ekranoplane

9:53 am

The Soviet Union’s gigantic nuclear equipped Ekranoplane, rusting on the shores of the Caspian Sea. With pictures.

Equipped with nuclear warheads and able to blast across the sea at 340 mph, the Lun-class Ekranoplane; part plane, part boat, and part hovercraft — is a Ground Effect Vehicle (GEV). A GEV takes advantage of an aeronautical effect that allows it to lift off with an immense amount of weight, but limits its flight to 16 feet above the waves. Its altitude can never be greater than the length of the wings.

The full Gingrich speech on space

11:47 pm

As noted by one commenter, the full Gingrich speech on space is available here on C-SPAN.

I have now listened to the whole speech, and can say without hesitation that everything I wrote in my previous post was correct. Gingrich is knowledgeable about space, science, and history. He is basing his proposals on past successful models where the U.S. government did nothing but buy the product developed by private individuals or companies. These proposals actually continue as well as accelerate the Obama administration’s efforts. And he is not proposing a giant pork program.

His proposal to have a moon base by 2020 is unquestionably campaign talk that won’t happen. Nonetheless, this proposal is aimed at energizing the American aerospace industry by focusing the government’s goals, which will then need to be purchased by the government from private companies. He also made it very clear he wants to shrink the NASA bureaucracy, reducing its budget while devoting ten percent of that savings (equal to billions of dollars) for prizes. The example of a $10 billion tax-free prize for the first to get to Mars was only for illustration. As he said,

The model I want us to build is largely is the model of the ’20s and ’30s, when the government was actively encouraging development but the government wasn’t doing anything. The government was paying rewards, it was subsidizing the mail. … We had enormous breakthroughs in aviation in the ’20s and ’30s at very little cost to the government because lots of smart people [outside the government] did it.

I beg everyone to listen to this speech, in its entirety. It illustrates a thoughtful man who understands history. Gingrich might not be a perfect man, and he certainly is not the perfect candidate for President, but don’t tell me what you think of him if you refuse to listen to him. For two decades too many people have eagerly expressed opinions about him without really listening to what he has actually said or done. And what he says here is reasonable, intelligent, and certainly worthy of consideration.

Gingrich’s speech on space

8:31 am

In the days ahead there is going to be a lot of talk about Newt Gingrich’s proposals for space exploration. I think it important that people actually see and listen to the entire speech before discussing it. Here is the longest clip I can find on youtube, covering the first seven and a half minutes. I think it is complete, but unfortunately, I can’t be sure. It doesn’t appear to include his remarks about awarding space prizes, and when it ends Gingrich does not appear to be finished. When I find a longer clip I will post it.

Several points immediately come to mind:

A new superconducting detector might supersede CCDs for astronomy

11:27 am

Good news: A new superconducting detector might supersede CCDs for large astronomical telescopes.

Ben Mazin, an astronomer at the University of California, Santa Barbara, believes that he is on the cusp of a camera breakthrough: his lab is working on a superconducting detector that could eventually replace the charge-coupled devices (CCDs) that have become de rigueur in both consumer and astronomical digital cameras. Mazin’s detectors, known as microwave kinetic inductance detectors (MKIDs), can simultaneously count photons, measure their energy and record each one’s time of arrival — something that CCDs can do only after the light is split with a prism or a grating, an extra step that adds to the loss of photons.

And you know that inevitably some variation of this technology is going to find its way into ordinary commercial products.

The Russian commission investigating the failure of Phobos-Grunt has concluded that the spacecraft failed because of Russian engineering errors, not U.S. sabotage.

Why am I not surprised? The Russian commission investigating the failure of Phobos-Grunt has concluded that the spacecraft failed because of Russian engineering errors, not U.S. sabotage.

I had suspected this whole kerfuffle was a fake issue inspired by Russian politicians. This report proves it.

Drilling in Antarctica

8:53 am

Drilling down to Lake Vostok has resumed in Antarctica.

This week, a Russian team drilling into Lake Vostok in the center of the Antarctic continent is likely to break through the ice to water. It will be the first time that a subglacial lake has been breached. These modern-day explorers hope to discover whether Vostok, which at 5000 km 3 is the third largest lake on the planet, is teeming with hidden, cold-loving life that could have evolved separately from the rest of the world for hundreds of thousands of years….

After drilling 3720 meters last February, time ran out for the team and the project was stymied just 29.5 meters from its destination as winter set in. Over the summer, they modified their drill bits and now the team is back at work with plenty of time to spare. They had left the large hole filled with antifreeze, so it was ready and waiting for them. It will remain open for years to come, Priscu says, potentially allowing other teams to sample the waters in the future.

In a break from standard practice, U.S. military has removed the links to its tracking data of Phobos-Grunt.

7:39 pm

Could the Russians be right!? In a break from standard practice, U.S. military has removed the links to its tracking data of Phobos-Grunt.

On Jan. 12, the Space Track website originally published information on the estimated re-entry track for Phobos-Grunt, a Russian probe that malfunctioned shortly after its November 2011 launch and was stuck in low-Earth orbit for more than two months.

After routine updates and revised estimates over the course of the next two days, the military removed links to these re-entry predictions and did not publish final confirmation data on the spacecraft’s fall on Jan. 15, according to Aviation Week.

A careful analysis of recent activities by U.S. radar show that it could not have affected Phobos-Grunt. Yet, the U.S. military has now taken actions that not only break with standard procedures, they draw attention to the issue. All very astonishing.

Orbital Sciences has once again delayed its first launch of Antares, the rocket that will lift its Cygnus cargo capsule to ISS.

Orbital Sciences has once again delayed its first launch of Antares, the rocket that will lift its Cygnus cargo capsule to ISS.

A hold-down test of Orbital Sciences Corp.’s Antares rocket, a prerequisite for the launch vehicle’s maiden flight, likely will not be completed before April because of ongoing tests and certification work on the vehicle’s launch pad at Wallops Island, Va., a launch official said.

As much as I am a fan of these private companies (Orbital and SpaceX), I also recognize the great risks. Both companies are building new rockets and capsules, and have many enemies. If they fail, those enemies will jump on their effort like sharks, ready to shut them down and move all government funding to NASA’s big heavy-lift program. Thus, they have to succeed. Better to delay and get things right then hurry and have them blow up in everyone’s face.

Skyscrapers As Spaceships

9:48 pm

Skyscrapers as spaceships.

As we spend more of our lives in cyberspace, we come to expect its primary characteristics (convenience, efficiency, abundance) to define our off-screen lives as well. And supertall, mixed-used skyscrapers are currently the most potent physical approximations of the virtual world we have. They’re environments designed for maximum convenience and efficiency, with elevators functioning like hypertext, taking you almost instantly from one mode of existence to the next. Push a button and you’re at work. Push another button, you’re at home.

There’s a lot more. Read the whole thing.

It looks like there will be no manned Soyuz missions launched from South America.

6:52 pm

It looks like there will be no manned Soyuz missions launched from South America.

An ESA study conducted between 2002 and 2004 found that because the Soyuz has not been designed to land in the sea, a French Guiana launch that had to be aborted would endanger the spacecraft and its crew as it would likely have to ditch in the Atlantic Ocean. The Soyuz spacecraft have always landed on land in the former Soviet territory of Kazakhstan.

Russia is now claiming that a U.S. military radar might have disabled Phobos-Grunt.

9:04 am

Looking for scapegoats: Russia is now investigating whether a U.S. military radar signal might have disabled Phobos-Grunt.

The state news agency RIA Novosti quoted Yury Koptev, former head of the Russian space agency Roscosmos, as saying investigators will conduct tests to check if a U.S. radar emissions could have impacted the Phobos-Ground space probe, which became stuck in Earth’s obit for two months before crashing down. “The results of the experiment will allow us to prove or dismiss the possibility of the radar’s impact,” said Koptev, who is heading the government commission charged with investigating causes of the probe’s failure.

The current Roscosmos head, Vladimir Popovkin, previously said the craft’s malfunction could have been caused by foreign interference. Deputy Prime Minister Dmitry Rogozin acknowledged U.S. radar interference as a possible cause but said it was too early to make any conclusions. “This version has the right to exist,” Rogozin said Tuesday. “There is evidence indicating that frequent disruptions in the operation of our space technologies occur in that part of the flight path that is not visible to Roscosmos and is beyond its control.”

Though this might be technically possible, it is incredibly unlikely. For Russian politicians to focus on this issue indicates serious problems in both their space engineering community and their political culture.

Geothermal energy developers plan to pump 24 million gallons of water into a dormant volcano in Oregon this summer to demonstrate a new way to generate electricity.

9:55 am

Geothermal energy developers plan to pump 24 million gallons of water into a dormant volcano in Oregon this summer to demonstrate a new way to generate electricity.

The irony I glean from this article is this: Pumping water underground to produce energy from geothermal sources (a source liked by the environmental movement) is good. However, pumping water underground to produce energy from gas or oil (energy sources hated by the environmental movement) is bad. And yet, what difference really is there between either effort?

Phobos-Grunt due to crash to Earth anytime in the next ten hours

9:00 am

path of Phobos-Grunt's reentry

Updated and bumped. An updated prediction from Aerospace now calls for Phobos-Grunt to come down sometime between 9 and 3 pm (Eastern). This puts the U.S. now out of danger, though Europe, South America, Africa, Australia, and the southern half of Asia all remain in the spacecraft’s path.

Watch your heads! Phobos-Grunt is due to crash to Earth anytime in the next ten hours. And unfortunately, this new prediction has it flying over both North America and much of Europe and Africa during that time period.
