Another fuzzy Dawn image?

12:11 pm

July 9 Vesta image

Another image of Vesta from Dawn has been released. This image was taken on July 9 from a distance of 26,000 miles away. It is definitely an improvement over the previous image, with more small details becoming visible. However, I once again wonder about the softness of the image. Look at the limb of the planet. It is soft against the black sky. This is not what one would expect from perfectly focused camera.

Dawn goes into orbit around Vesta next week. We sure learn then for sure if there is a problem with its camera, or whether I am merely being a bit too nervous.

Being tone deaf is not a good way to fund a government space program

11:59 am

Yesterday the House appropriations committee’s released budget numbers that included no additional funds for commercial space, limiting the subsidies to $312 million, the same number as last year and significantly less than the $850 million requested by the Obama administration.

This is what I have thought might happen since last year. The tone deaf manner in which the Obama administration has implemented the private space subsidies is leaving all funding for NASA vulnerable.

Astronomers have found two new brown dwarf stars only 15 and 18 light years away

11:08 am

Astronomers have found two new brown dwarf stars only 15 and 18 light years away.

Most brown dwarfs have reached surface temperatures below the “oven temperature” of about 500 Kelvin (about 230 degrees Celsius), may be even as cool as the temperature at the surface of the Earth. The search for these elusive neighbours of the Sun is currently in full swing. It cannot be excluded that ultracool brown dwarfs surround us in similar high numbers as stars and that our nearest known neighbour will soon be a brown dwarf rather than Proxima Centauri.

NASA stalls, Texas lawmakers fume

10:12 pm

The law is such an inconvenient thing: In a bipartisan effort, Texas lawmakers roast NASA administrator Charles Bolden for not meeting mandated Congressional deadlines for Congress’s personally designed rocket, the program-formerly-called-Constellation.

The heavy-lift rocket and capsule that Congress insists NASA build is a complete waste of money and nothing more than pork. It will never get built, mainly because Congress has given NASA less money and less time to build it than they did for Constellation under the Bush administration. Unfortunately, the reason they continue to require NASA to build it is to provide pork to their districts.

In a perfect world this funding would be cut now, especially considering the state of the federal debt.

Second ARTEMIS space probe about to enter lunar orbit

8:27 pm

The second ARTEMIS space probe will enter lunar orbit on Sunday.

“With two spacecraft orbiting in opposite directions, we can acquire a full 3-D view of the structure of the magnetic fields near the moon and on the lunar surface,” said Vassilis Angelopoulos, principal investigator for the THEMIS and ARTEMIS missions and a professor of space physics at UCLA. “ARTEMIS will be doing totally new science, as well as reusing existing spacecraft to save a lot of taxpayer money.”

White dwarf stars in a dance of death

8:24 pm

White dwarf stars in a dance of death.

[The binary pair of] white dwarfs are so near they make a complete orbit in just 13 minutes, but they are gradually slipping closer together. About 900,000 years from now – a blink of an eye in astronomical time – they will merge and possibly explode as a supernova. By watching the stars converge, scientists will test both Einstein’s general theory of relativity and the origin of some peculiar supernovae.

The two white dwarfs are circling at a bracing speed of 370 miles per second (600 km/s), or 180 times faster than the fastest jet on Earth. “I nearly fell out of my chair at the telescope when I saw one star change its speed by a staggering 750 miles per second in just a few minutes,” said Smithsonian astronomer Warren Brown, lead author of the paper reporting the find.

The brighter white dwarf contains about a quarter of the Sun’s mass compacted into a Neptune-sized ball, while its companion has more than half the mass of the Sun and is Earth-sized. A penny made of this white dwarf’s material would weigh about 1,000 pounds on Earth. Their mutual gravitational pull is so strong that it deforms the lower-mass star by three percent. If the Earth bulged by the same amount, we would have tides 120 miles high. [emphasis mine]

House spending panel cuts John Holdren’s science office budget by 55%

7:18 pm

The House spending panel today proposed cutting the budget of the White House Office of Science and Technology Policy (OSTP) office, run by John Holdren, by 55%.

“OSTP has chosen to disregard a strong and unambiguous legislative prohibition on bilateral engagement with China or Chinese-owned companies,” says language accompanying the 2012 bill, to be voted on tomorrow by the full appropriations committee. “OSTP’s behavior demonstrates a lack of respect for the policy and oversight roles of the Congress.”

I think the Obama administration is about to discover that ignoring the law as passed by Congress can have bad consequences.

Gore Announces New Campaign and Worldwide Event to Re-energize Global Warming Hysteria

12:57 pm

Al Gore has announced a new campaign “to broadcast the reality of the climate crisis and mobilize citizens to help solve it.”

And I ask: what the hell does a propaganda campaign tell us about the climate? The answer: nothing. Just because you say so, Al, does not make it so.

On another note, satellite data continues to show absolutely no warming for the past decade.

wings in space

12:49 pm

James McLane points out that the shuttle shape is not the only way to build a spaceship.

In an email to me Jim noted that he “is still trying to save NASA.” My response to him was that trying to save NASA right now is more hopeless than Don Quixote chasing a windmill. However, the engineering ideas he outlines in his essay are just the kind of innovative thinking required by the new private companies. And the more ideas the merrier!

Public debt and the peril of Obamacare

11:51 am

Public debt and the peril of Obamacare.

Countries with universal healthcare fall into two camps:

1. Totalitarian regimes like Cuba and North Korea, and authoritarian Third World countries in the Middle East and Africa.

2. Western nations that free-ride off of American military spending and its provision of international security, but nonetheless run unsustainable budgets with immense debts trying to pay for their social welfare states. [emphasis mine]

In other words, we had better repeal this monstrosity or we face economic collapse, probably preceded by a dictatorship.

House Budget Bill Would Leave it to NASA To Apportion Bulks of Cuts

9:49 pm

The House bill that brings NASA’s budget back to 2008 levels essentially leaves it to NASA to figure out what to cut.

If true, what this means is that NASA itself will have to choose what it considers important. The one problem is that according to this article Congress is still requiring NASA to spend $3 billion on the program-formerly-called-Constellation. which gives the agency less flexibility in doling out the cash.
