Look out. The Mirror Bees are coming this week on planetary radio. Hi everyone, welcome to Public Radio's travel show that takes you to the final frontier.

I'm at Kaplan of the Planetary Society. It's only a matter of time.

There's a rock out there with our name on it. So what do we do when we see it headed our way?

Max Vazile has a new answer to that question and he calls it

wimps or weekly interacting massive particles. Never heard of them? Well Bill Nye is

here to tell you that they might make up most of our universe. And it's not that

Bruce Betts is a wimp, he's just under the weather, but that won't stop him

from joining me for this week's edition of What's Up?

What's no longer up is Endeavor.

The shuttle made a night landing at the Kennedy Space Center on Sunday, February 21.

It had spent two weeks in space, most of that docked with the International Space Station,

where it delivered the tranquility module.

Joined by middle school kids in an engineering competition,

President Barack Obama made a White House call

to the commanders of Endeavor and the ISS.

I just want to repeat and I think I speak for all the of Endeavor and the ISS.

I just want to repeat and I think I speak for all the young people here and everybody back

home, how proud we are of you, how excited we are about the work that's being done on the space station and how

committed we are to continuing human space exploration in the future.

President Obama talking with the crews of space shuttle endeavor and the international space

station as the buzz surrounding the President's proposed NASA budget continues.
