Russian scientists about to drill into Lake Vostok
Russian scientists are about to drill into Lake Vostok, a lake buried for the last 14 million years beneath the almost two and a half mile thick Antarctic icecap.
A look at the U.S. government’s planned budget for climate research
The next time someone begins ranting about how the money from “big oil” is used to attack the science of global warming, tell them to take a look at this post, which outlines in detail the more than $2 billion that the U.S. government plans to spend on climate change research in 2011 alone (too much of which is unfortunately used by partisans like James Hansen to try to prove the Earth is warming).
The Corrs – No Frontiers
An evening pause:
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!
The climate has been cooling since 2003, according to ocean data
From Watts Up With That: Data from the Argos ocean floats says that the Earth’s climate, as measured by the heat content of the ocean, has been cooling since 2001, not warming as predicted by climate models. You can download the actual science paper, “The Energy Balance of Earth,” here.
Congress’s inability to pass any full-year spending bills for 2011 will likely delay the launch of two civilian weather satellites by more than a year
It ain’t just NASA that’s having budget problems: The lack of a budget from Congress is going to delay the launch of two civilian NOAA weather satellites by more than a year.

A private science mission to an asteroid?
A proposal to revive a project to send a private science probe to an asteroid.
The original project, NEAP, was proposed back in 1997 by the late Jim Bensen of SpaceDev (now Sierra Nevada). Benson wanted to not only do research, but he planned to claim the asteroid as his property upon landing. Though his proposal never flew, it was clearly a forerunner to today’s resurgence of the private space industry, and in many ways kickstarted that resurgence.

The early Lunar Orbiter images, taken in the mid-1960s, have been reprocessed and recovered, in a spectacular manner.

University of Virginia resists releasing climate documents
Another whitewash? The University of Virginia is resisting releasing a variety of climate documents being requested under the state’s Freedom of Information Act (FOIA). Key quote:
In response to a previous FOIA request, U.Va. denied these records existed. However, during Cuccinelli’s pre-investigation under the Virginia Fraud Against Taxpayers Act (“FATA”), a 2007 law passed unanimously by Virginia’s legislature, which clearly covers the work of taxpayer-funded academics, U.Va. stunningly dropped this stance.
