Climate change study had ‘significant error’: experts
Climate scientists admit that a climate change study which claimed the Earth would warm by more than 4 degrees Fahrenheit in about a decade had “significant errors”. Key quote:
Scientist Scott Mandia forwarded to AFP an email he said he sent to Hisas ahead of publication explaining why her figures did not add up, and noting that it would take “quite a few decades” to reach a warming level of 2.4 degrees Celsius. “Even if we assume the higher end of the current warming rate, we should only be 0.2C warmer by 2020 than today,” Mandia wrote. “To get to +2.4C the current trend would have to immediately increase almost ten-fold.”

The state of Virgin Galactic
The state of Virgin Galactic. Key quote:
One of the great things about Galactic is that it’s still built on a non-government market — that is to say, the individual spacefarer market, the space tourist market, call it what you will. As you know, we’re now over 400 people [who have paid deposits for a spaceflight], and over $55 million dollars in deposits. None of that is based on a government program. I think that’s really encouraging. It’s a sign that there are markets outside the government, and that you can build a human spaceflight business around those markets.

Bad news for NASA, good news for private space
Earlier this week NASA submitted a report to Congress reviewing the design and construction status of the heavy-lift rocket and manned capsule that Congress has required them to build and launch by 2016. NASA’s conclusion: the space agency doesn’t think it can do the job in the schedule or budget that Congress has provided.
NASA does not believe this goal is achievable based on a combination of the current funding profile estimate, traditional approaches to acquisitions and currently considered vehicle architectures. . . . We will not commit to a date that has a low probability of being achieved.
NASA’s conclusions here are not surprising. The agency had been having trouble building Constellation on the much bigger budget and longer schedule given to them by past Congresses. For them to build the-program-formerly-called-Constellation for less money and in less time is probably impossible.
Nonetheless, this was the response of the Senate Commerce committee:
The production of a heavy-lift rocket and capsule is not optional. It’s the law.
This is why I have been saying that the money for this program is nothing more than pork. Congress knows that nothing can be built on this budget, but wants the money spent nonetheless, to keep people employed in their districts.
Meanwhile, in sharp contrast, Space Adventures yesterday announced a new deal with Russia, whereby the Russians have agreed to build and launch one extra Soyuz capsule per year, beginning in 2013, to fly 3 tourists to ISS. In addition, there is this report today about how SpaceX is successfully meeting all its milestones in building its cargo ferry for ISS. An earlier report last week also noted how Orbital Sciences is also moving forward with its cargo ferry, with a planned first test launch by the end of 2011.
All in all, this news is not good news for NASA. The space agency’s manned spaceflight program appears to have two futures, neither of which will involve it continuing to build rockets or fly humans into space. In one option, the new Congress, when it finally sits down to write a budget, will decide that pork and happy constituents are more important than a balanced budget, and will appropriate the money for the-program-formerly-called-Constellation. NASA will struggle hard to build it, but will not succeed. Thus, no government-built manned space program.
In the second option, Congress will agree with me and decide that it just doesn’t have money for pork, especially considering the terrible state of the federal budget. Moreover, seeing the success of the private efforts of SpaceX, Orbital Sciences, and Space Adventures, Congress will wonder why it needs to pour more billions into a vain effort by NASA to build something it can’t, when there are other private companies that can do it, and do it for less. In this circumstance, it will be very easy for them to cut the-program-formerly-called-Constellation. Once again, no NASA manned program.
Neither scenario is actually a bad thing. What we are actually seeing play out here is the free competition of different companies attempting to provide a service to a customer, and the customer eventually picking the best company from which to buy the product. NASA, as a government agency, simply can’t compete, and unless Congress decides to provide them welfare, will lose this competition hands down.
The U.S. will still have the capability of getting into space, but for far less money. And having multiple private companies competing to provide this service will also encourage innovation, something the rocket industry has sorely needed these past five decades.
NASA submits its Heavy Lift rocket proposal to Congress
NASA has submitted its Heavy Lift rocket proposal to Congress. However, NASA also noted bluntly that:
“Neither Reference Vehicle Design currently fits the projected budget profiles nor schedule goals outlined in the Authorization Act.”
In other words, they can’t build it for the money or in the timeframe they’ve been given by Congress.
Didn’t someone say this already? Several times?

New results from the Sloan Digital Sky Survey
From the second press conference at the AAS meeting today, results from the Sloan Digital Sky Survey, which has been surveying the sky in incredible detail over the past eleven years:
- The largest digital color image of the heavens, covering one third of the sky, imaging a half a billion stars and galaxies. Despite looking the sky in wide-field view, the data also has incredible close-up detail. This has and will continue to provide astronomers a precise baseline reference for future research.
- A 3D reconstruction of the local galactic neighborhood, showing the three dimensional position of the visible galaxies within a billion light years. They plan to use the new Sloan color image above to further extend this 3D reconstruction out to seven billion light years.
- The largest map of the Milky Way’s outer regions, showing the streams of stars captured from other galaxies, absorbed in the past galactic mergers that formed the Milky Way.
All this data will be available for anyone to dig around in.

Imaging the ground under the Greenland ice sheet
In a paper published today in Geophysical Research Letters of the American Geophysical Union, scientists describe how they have been able to produce remarkably detailed images of the ground buried almost a mile under the ice sheet of Greenland. These radar techniques are the same used in the past by spacecraft to image the hidden surface of Venus, only far more sophisticated.
This image from the paper compares the radar image of the Greenland surface (on the left) to an photograph of a known surface feature in the Northwest Territories of Canada, produced thousands of years ago by the giant icesheets of the last Ice Age. Both are at the same scale, about a third of a mile across, and are looking at the surface at an oblique angle of about 45 degrees. With the radar-produced image on the left, sunlight is simulated as coming from the right, with the elevation increasing as the colors go from green (lowest) to yellow to brown to purple (highest).
The long grooves, generally 30 to 100 feet deep and extending sometimes several miles, are produced as the icesheet slides across the ground. In the radar image, however, these grooves are slowly being ground out now.
It is the resolution of this technique that is so exciting. That they can look through ice almost a mile thick and resolve objects that are only tens of feet across tells me that someday it will be possible for spacecraft to map the smallest features on the surface of Venus or Titan. More exciting, this suggests that the technology will one day exist to even map the unknown surface of gas giants like Jupiter or Saturn, and do it in breathtaking detail.
Yowza!
