Pluto’s atmosphere is expanding, and scientists don’t know why

5:59 pm

Pluto’s atmosphere is expanding, and scientists don’t know why.

Pluto travels along a highly elliptical path and last passed closest to the sun in 1989. Many planetary scientists expected the atmosphere to shrink as the icy orb began receding from the sun’s warmth. The unanticipated expansion may be related to changes in the darkness of the orb’s surface a decade or so ago, which may have caused the surface ices to absorb more solar radiation and more efficiently evaporate. Or, Greaves suggests, long-term variations in the sun’s ultraviolet output, changes linked to the roughly 11-year cycle of solar activity, may be playing a role.

NASA Awards Next Set Of Commercial Crew Development Agreements

11:59 pm

NASA has awarded the next set of commercial crew development agreements, giving contracts worth from $22 to $92 million to four companies, Blue Origin, Sierra Nevada, SpaceX, and Boeing. More here and here.

The amounts that NASA is giving these companies is minuscule, compared the monies spent on the program-formerly-called-Constellation. Yet I bet they all get their rockets/capsules launched and in operation, supplying cargos and crews to low Earth orbit, before NASA even test fires its heavy-lift rocket.

China finds SpaceX’s launch prices challenging

7:08 pm

Competition! China finds SpaceX’s launch prices low — and a challenge to meet.

Declining to speak for attribution, the Chinese officials say they find the published prices on the SpaceX website very low for the services offered, and concede they could not match them with the Long March series of launch vehicles even if it were possible for them to launch satellites with U.S. components in them.

No deal

No deal. Key quote:

If Democrats are not going to do even minor surgery on Medicare and Medicaid and Republicans are not going to raise taxes, there is no hope of big budget deal to cut a deficit now running at 11 percent of gross domestic product.

And that raises another question. How long can the Federal Reserve continue financing these deficits? China, choking on U.S. debt, is reportedly beginning to divest itself of U.S. bonds. Japan will need to sell U.S. bonds to get hard currency to repair the damage from the earthquake and tsunami. And the Fed is about to end its QE2 monthly purchases of $100 billion in U.S. bonds. Where is the Fed going to borrow the $125 billion a month to finance this year’s deficit of $1.65 trillion, and another of comparable size in 2012? Bill Gross’ Pimco, the world’s largest bond fund, has sold all his U.S. bonds and begun to short U.S. debt. Pimco is betting that the value of U.S. Treasury bonds will begin to fall.

We may be about to enter a maelstrom.
