Did the Earth once have two moons? And did they collide?

Did the Earth once have two moons?

Both satellites would have formed from debris that was ejected when a Mars-size protoplanet smacked into Earth late in its formation period. Whereas traditional theory states that the infant Moon rapidly swept up any rivals or gravitationally ejected them into interstellar space, the new theory suggests that one body survived, parked in a gravitationally stable point in the Earth–Moon system.

This new model also posits that the two moons eventually collided, producing the moon we have today.

Lack of U.S. government interest in commercial refueling mission causes problems

A lack of U.S. government interest in a privately designed satellite refueling technology has caused the company to pull back its plans.

MDA had signed a contract with the communications satellite company Intelsat to refuel some of its orbiting satellites, but needed additional customers to make a go of it. It had hoped the U.S. Defense Department would show interest, but they have not.

This is exactly where the government should be investing its capital, and that it is not tells us a lot about the real lack of sincerity behind the Obama administration’s claims that it wants to encourage private space. I also suspect that the turf war with satellite companies and defense contractors helped discourage Defense Department interest.

Moody Blues – Your Wildest Dreams

An evening pause:

And when the music plays
And when the words are
Touched with sorrow
When the music plays
I hear the sound
I had to follow
Once upon a time
Once beneath the stars
The universe was ours
Love was all we knew
And all I knew was you
I wonder if you know
I wonder if you think about it
Once upon a time
In your wildest dreams

Dow dives below 12,000

The Dow today dived below 12,000, a nine-month low.

The report above tries to look past the just signed debt agreement, but I wonder if maybe it was the debt deal itself that worried investors, since the deal really did little to gain control of the federal government’s out-of-control spending.

Update: “The joint committee process is yet another promise by Congress that it will get spending under control β€” just not now, but rather some time in the future, always in the future.”
