Space Junk

While a cascade in LEO is something to be very concerned about, this Pop Sci article gets this quite wrong:

If a chain reaction got out of control up there, it could very quickly sever our communications, our GPS system (upon which the U.S. military heavily relies)…

Most communications satellites are in GEO, thousands of miles above LEO, and GPS are in twelve-hour orbits, also very high, but not as high as GEO. Most of our communications would remain intact, as would GPS.


Sestak or Gibbs? Someone is lying.

I know where I’d put my money.

[Update a few minutes later]

As usual, it’s not the crime, it’s the cover up. And why am I not shocked that there’s a Clinton involved?

[Update a few more minutes later]

I, like everyone else, expect a White House release on this late this afternoon. It’s merely a coincidence that it’s a Friday just before a three-day weekend.

[Update a while later]

Well, the WH PR staff blew it. You’re supposed to release these things late in the afternoon, after it’s impossible to get hold of anyone to ask questions, not in the morning.

[Update a few minutes later]

Republicans are skeptical. So am I. All this does is raise more questions (like why did Sestak say “someone in the White House,” which Bill Clinton hasn’t been for almost a decade).

[Update a while later]

Well, now that they’ve had time to coordinate their stories, Sestak confirms it. Even though it’s not what he said the first time.

Lying then, or lying now? I know where my money is.

[Update a few minutes later]

The Sestak smell test. And why did the White House contact Sestak’s (lawyer) brother yesterday?

Oh, what a tangled web we weave…

[Late morning update]

Jonah Goldberg isn’t buying it, either:

If it wasn’t a job offer but instead was some third-rate perk, he shouldn’t have pretended otherwise to seem like the one honest man in the whorehouse of politics. I hope he gets hounded by local press asking him to explain the disconnect. Something like: “You said you were offered a job to get out of the race. This wasn’t a job. Were you exaggerating then or are you lying now?”

Again, I know where I’d put my money.

XCOR Update

I’m seeing tweets from the ISDC that Jeff Greason is saying Lynx rollout and flight tests are about a year from now.

This is interesting:

XCOR has plans to develop an orbital vehicle.

Jeff has been saying that he has some ideas along those lines. I wonder how much he’s revealing publicly?

[Update a while later]

A lot more XCOR tweets over at Space Transport News.

Peter Beinart’s Hero

Ron Radosh has some thoughts on anti-Israeli Jews.

[Update late morning]

More thoughts, and good ones, from Noah Pollack:

The sad truth is that Peter Beinart isn’t any kind of trailblazer or whistleblower, and he most certainly has not earned himself any trouble by coming out as an Israel-basher. He is someone who has rather belatedly fallen completely and predictably into line with the demands his ideological compatriots make for orthodoxy when it comes to their increasingly passionate interest in assaulting Israel and championing the Palestinian cause. In Beinart’s work, we are not witnessing an act of courage but rather a spectacle of conformity.

I used to think that Beinart was smarter than that.
