NASA continues to stall on heavy-lift rocket

10:41 am

It ain’t ever happening: NASA continues to stall on their final design for Congress’s mandated heavy-lift rocket.

No one should be surprised by this. Obama has never wanted NASA to build this rocket, when it was Constellation and now when it is the program-formerly-called-Constellation. Moreover, Congress hasn’t given NASA enough money or time to do it anyway. Better the program die and the money is used for something else, or cut entirely in order to reduce the crushing federal debt.

More evidence dinosaurs were warm-blooded

11:57 am

A new study has found new evidence that dinosaurs were warm-blooded and active, unlike modern reptiles. Even more surprising,

“The dinosaurs appeared to be even more active than the mammals. We certainly didn’t expect to see that. These results provide additional weight to theories that dinosaurs were warm-blooded and highly active creatures, rather than cold-blooded and sluggish.”

Where to find life in the Milky Way galaxy

11:05 am

A paper published today on the Los Alamos astro-ph preprint website has attempted to model the habitable zones within the Milky Way galaxy. From the abstract:

We predict that ~1.2% of all stars host a planet that may have been capable of supporting complex life at some point in the history of the Galaxy. Of those stars with a habitable planet, ~75% of planets are predicted to be in a tidally locked configuration with their host star. The majority of these planets that may support complex life are found towards the inner Galaxy, distributed within, and significantly above and below, the Galactic midplane.[emphasis mine]

They took into consideration the hazard of supernovae for killing off planetary life, as well as other factors such as the where the necessary heavier elements would be available for producing planets.

Highest Water in a Decade Expected at Lake Powell

3:04 am

The highest water level in a decade is expected at Lake Powell by August.

Lake Powell’s rising water level is a result of the long and wet winter this year. An above-average snowpack, with late snows and unseasonably cold weather has lead to a slower melt than usual. As of May, the snowpack that feeds Lake Powell was 30 percent higher than average, with only 50 percent of the accumulated snowpack melted. [emphasis mine]

I thought Al Gore told us this wasn’t going to happen anymore.
