"Obama plan to land on asteroid may be unrealistic for 2025."

Headline that made me laugh.

Anyway, what's unrealistic? In 2025, he won't be President. So it's totally realistic of him to blab about crap he won't have to do. And I'm quite happy to have him dreaming about the distant future instead of inflicting things on us right now.

The moon is 240,000 miles away. A trip to an asteroid would be 5 million miles — at a minimum.

Why go?

Why not!

Asteroids have always been passed over as a destination for human explorers. Then-president George H.W. Bush wanted NASA to go to Mars, while his son, George W. Bush, chose the moon. During the past six years, NASA spent $9 billion building a spaceship, rocket and other gear to help reach the second Bush's goal of returning humans to the lunar surface by 2020.

In February, Obama took steps toward killing Bush's moon program, which was beset by technical troubles and money woes. Two months later, in a speech at Cape Canaveral, Obama announced that the astronauts' next stop is an asteroid.

A President's got to be about going somewhere... somewhere else.

So far, the Obama administration has been quiet on the need for a major sum of money to accomplish his goal.

Ha.

What do you do once you get to an asteroid?

•Humans can't walk or drive on an asteroid.

... [E]ven the biggest asteroids have practically no gravity. So anything in contact with the surface could easily drift away.

Like thoughts in the cranium of a President.

"You don't land on an asteroid," says former Apollo astronaut Rusty Schweickart, a longtime advocate of asteroid studies. "You pull up to one and dock with it. ... And getting away from it, all you have to do is sneeze and you're gone." He envisions a spaceship hovering next to the asteroid and occasionally firing its thrusters to stay in place.

Astronauts wouldn't walk on an asteroid. They would drift next to it, moving themselves along with their gloved hands.

La la la. Float along!



In gloves!

To keep from floating into space, crewmembers could anchor a network of safety ropes to the asteroid's surface, but "that has its own risks, because we don't understand how strong the surfaces of asteroids are and whether (they) would hold an astronaut in place," says Daniel Scheeres, a planetary scientist at the University of Colorado.

Lasso an asteroid!

The minimal gravity also means that any dust the astronauts stir up will hang in a suspended cloud for a long time. Because there's no weather on an asteroid, there's no erosion to smooth the dust particles.

"It's all going to stay pretty razor-sharp. ... It's not the most friendly stuff in the universe," Korsmeyer says. Keeping humans safe as they explore an asteroid "is going to be really tricky."

Dodge razor-sharp dust!

Go 5 million miles to paddle your gloved hands across the surface of a rock and stir up a cloud of razor-sharp dust particles that will — once you leave — hang there endlessly.

IN THE COMMENTS: Lemondog says:

Any chance the little prince could speed it up???!

Mebbe......next year?

Now we know the B in B-612 stands for Barack.

Just so, you might say to them: "The proof that the little prince existed is that he was charming, that he laughed, and that he was looking for a sheep. If anybody wants a sheep, that is a proof that he exists." And what good would it do to tell them that? They would shrug their shoulders, and treat you like a child. But if you said to them: "The planet he came from is Asteroid B-612," then they would be convinced, and leave you in peace from their questions.

OMG! He's not a natural born citizen! But he was charming, he laughed, and he found quite a lot of sheep.
