Saturn’s weird moon Pan

Pan

New images from Cassini have provided scientists their first sharp images of Saturn’s moon Pan, and what those images show is something really weird. The image on the right is only one sample, with the link providing more.

Pan orbits in a gap between two rings, and the ridge might have accumulated from material from those rings. Then again, maybe not. It will take more data to I think completely unravel how this moon got to look like it does.

Congress micromanages rocket development at ULA

Corrupt Congress: Even though ULA favors Blue Origin’s BE-4 engine for its Vulcan rocket, various elected officials in Alabama are pushing the company to use Aeroject Rocketdyne’s AR-4 engine instead.

At the end of February, two US representatives, Mike Rogers of Alabama [Republican] and Mac Thornberry of Texas [Republican], decided to push a little harder. On February 28, they sent a letter to Lisa Disbrow, the acting secretary of the US Air Force, and James MacStravic, who is performing the duties of the undersecretary of defense for acquisition, technology, and logistics. In addition to reiterating a desire that ULA continue to fly a second rocket, the Delta IV Heavy, the letter urges the Pentagon officials to be skeptical about the BE-4 engine.

“The United States Government (USG) must have a hands-on, decision-making role… in any decision made by United Launch Alliance to down-select engines on its proposed Vulcan space launch system, especially where one of the technologies is unproven at the required size and power,” the letter states. “If ULA plans on requesting hundreds of millions of dollars from the USG for development of its launch vehicle and associated infrastructure, then it is not only appropriate but required that the USG have a significant role in the decision-making concerning the vehicle.” The letter then goes on to say the Air Force should not give any additional funding to ULA, other than for current launch vehicles, until the company provides “full access, oversight of, and approval rights over decision-making” in its choice of contractors for the engines on Vulcan.

The article also mentions porkmaster Senator Richard Shelby (R-Alabama), who also favors Aerojet Rocketdyne because they say they will build it in Alabama. Note also that these elected officials are not only trying to pick the winner in the private competition between these two rocket engines, they also want to force ULA to keep using the Delta rocket, even though it is very expensive and not competitive with the newer rockets being developed by other companies. And their only reason for doing so is because they provide jobs for their districts.

This one story illustrates perfectly the corruption that permeates both parties in Congress. While it is more likely that Democrats will play this pork game, there are plenty of corrupt Republicans who play it as well. These petty dictators all think they have the right to interfere in the private efforts of Americans, whether it involves building a new rocket or buying health insurance. And all we get from this is a poorer nation and a bankrupt federal government.

Stratolaunch to fly in 2017?

The competition heats up: In an interview Paul Allen has revealed that he hopes to begin flight tests of his gigantic Stratolaunch airplane, the largest ever built, later this year.

No word on the rocket that this air-launched system would launch, however. In fact, it appears that no one seems interested in providing one. This could change once the plane is flying.

Meet the fascist professors at Middlebury College

Following the violent protests at Middlebury College in Vermont that injured a professor during a speaking event by author Charles Murray last week, two professors issued a “statement of principles” in favor of free speech and expressing opposition to such violence. The following, only an excerpt, gives a flavor of the whole statement:

Exposure to controversial points of view does not constitute violence.

Students have the right to challenge and to protest non-disruptively the views of their professors and guest speakers.

A protest that prevents campus speakers from communicating with their audience is a coercive act.

No group of professors or students has the right to act as final arbiter of the opinions that students may entertain.

No group of professors or students has the right to determine for the entire community that a question is closed for discussion.

The purpose of college is not to make faculty or students comfortable in their opinions and prejudices.

So far 79 professors at Middlebury College have put their names to this document. What is interesting, however, is a list of those professors who have not signed this basic statement in favor of free speech. An academic at a different college took a close look at the signatories, and found not surprisingly that no teachers from certain departments had signed. Before you click to see, I am willing to bet you can guess many of the departments and their teachers who oppose the idea of free speech. There are surprises however:

Rand Paul introduces his Obamacare replacement

Competing crap: Senator Rand Paul, who opposes the Obamacare replacement introduced by the Republican leadership, introduced his own bill today to replace Obamacare.

I’ve looked at the summary [pdf] of his bill, and it contains most of the same problems contained in the Republican leadership’s proposal. Neither repeals Obamacare really, since both keep the ability of everyone to wait until they are sick before they buy health insurance, thereby guaranteeing that every health insurance company will go bankrupt.

We need Congress to repeal Obamacare, clean and simple. The tinkering by Congress in this business has only caused problems. The more tinkering they do, the more problems they will cause. They need to get out, now.

Blue Origin signs second contract for New Glenn

The competition heats up: One day after announcing its first launch contract, Blue Origin announced today a second contract for its New Glenn rocket.

In a tweet this morning, Blue Origin Founder Jeff Bezos said OneWeb has reserved five launches using the rocket, bringing to six the number of missions in the New Glenn manifest.

So far I can find no information about the prices being charged by Blue Origin for these launches. I suspect they are giving their customers discounts for being the first, but this is not confirmed yet.

At the crest

Looking north at the crest

Cool images time! The image above, cropped and reduced to show here, is a panorama that I have created from the most recent images sent down from Opportunity yesterday. The rover sits on the crest of the rim of Endeavour Crater, and this panorama looks north at that crest, back in the direction where the rover has come. The rovers tracks can be seen fading away into the distance slightly to the left of the crestline..If you click on the picture you can see the full resolution image.

The crater floor is to the right, the plains that surround the crater are to the left.

Below is another panorama, created by me from the same images sent down today, this time looking south at the crest in the direction Opportunity is heading. Once again, if you click on the picture you can see the full resolution version.

The full set of today’s images from Opportunity suggest that the science team took them to assemble a full 360 degree panorama before they begin the journey south to the gully that is just now becoming visible at the southernmost edge of the most recent overhead traverse image. To get to that gully they will now have to descend off the crest and down outside the rim of Endeavour Crater, moving to the right in the panorama below. This is therefore their last opportunity for awhile to get a good view from a high overlook.
