Waiting for the Phoenix

Mars is scheduled to get another curious visitor from Earth on Sunday the 25th. The Phoenix robot lander will touch down at the Red Planet’s North Pole and "taste and sniff" the soil and buried water-ice that other robot instruments have shown to be there. Why bother? Aside from the Moon, Mars is the best spot for human colonies beyond the home planet. NASA has a blog that will begin coverage of Phoenix on Monday.

The whirlpool galaxy

One of the spectacular benefits of a journey into the black, even if it is thirty million light years away. 

Which is bigger?

Just in case you have troubling remembering the relative sizes of the rocky planets, like a certain blogger I read whose name I will not mention, who thought Mars was bigger than the home planet.

Through ultraviolet eyes

One of a series, this NASA ultraviolet image of Saturn was taken when the rings were at maximum tilt of 27 degrees toward Earth. Saturn has seasonal tilts away from and toward the sun, much the same way the home planet does.

Carrington Super Flare

It’s quiet on the sun these days. Too quiet. No sun spots of note. Some scientists regard that as possibly the cause of much of the late snow this spring and say it could be forecasting colder days ahead. But, theoretically, that won’t stop another brief super flare from our nearest star like the one that disrupted telegraph communications, caused auroras as far south as Cuba and surprised English solar astronomer Richard Carrington, in September, 1859. Imagine what another one would do to our electronic-dependent world. It could become known as the Day Silicon Died.

Forget the moon and Mars

That seems to be Rand Simberg’s conclusion in Popular Mechanics. Even McCain, the likely next president, seems lukewarm on W’s backing of returning to the moon for a permanent base–now that millions have been spent planning to do so. And, without a microgravity base out there to start from, that’s far less expensive than trying to get out of Earth’s gravity well, you can forget human travel to Mars anytime soon. At least the NYTimes will be happy. They’ve always favored robots over astronauts.

The Running Chicken Nebula. Can you find the running chicken? No? Me neither.
