Virgin Galactic awards contract

8:58 am

The competition heats up: Virgin Galactic has awarded a contract to a Waco company to strengthen the wings of a 747 it intends to use the first stage for LauncherOne.

L-3’s work will make the left wing stout enough to support a rocket that would launch in flight from beneath the wing. This rocket would propel satellites into space for commercial and government customers. Company spokesman Lance Martin said that for confidentiality reasons he could not disclose the value of the contract or the length of the plane’s stay in Waco. He said performing work for Virgin Galactic and Branson should enhance L-3’s image, saying, “the customer speaks for itself.”

I suppose I should be excited by this, as it suggests that LauncherOne is moving forward. Considering Virgin Galactic’s history, however, I find myself sadly disinterested. I won’t get excited by this company again until they actually begin flying something.

ULA official resigns

8:48 am

In an update to the story last night about the head of ULA rejecting comments made by one of his chief engineers, that engineer has now resigned.

[Brett Tobey, formerly ULA vice president of engineering] resigned his position, effective immediately, ULA chief executive Tory Bruno said in a statement. ULA is a joint venture of Lockheed Martin Corp and Boeing. “The views, positions and inaccurate statements Mr. Tobey presented at his recent speaking engagement were not aligned with the direction of the company, my views, nor the views I expect from ULA leaders,” Bruno said in the statement.

In other words, we can’t have too much honesty here. There are games that Congress and ULA play with each other to justify the billions in subsidies the government gives ULA, and to note these games in a straightforward way is to note that the emperor has no clothes. We can’t have that.

I hope Tobey finds a job at SpaceX.

ULA head rejects his engineer’s remarks about Aerojet Rocketdyne

9:47 pm

The heat of competition: The head of ULA has disavowed his engineers’ remarks that plugged Blue Origin’s engine for the Atlas 5 while dissing Aeroject Rocketdyne’s.

The engineer was giving a talk at the University of Colorado this week where he made it pretty clear that ULA favors Blue Origin over Aerojet Rocketdyne, but had to make believe they were treating both companies equally in the competition to replace the Atlas 5’s Russian engines in order to keep the Air Force happy. Bruno is probably now doing some damage control, as the government still wants to justify the Aerojet Rocketdyne contract (whose only real purpose was as a government pork barrel jobs program). Considering all the money the Air Force and congressmen give to ULA, he has to keep them both happy. And telling the world that their Aerojet contract is a waste of government money is not a very good way to do this.

Nonetheless, he also admitted that Blue Origin is way ahead in development, and is thus most likely to win the competition anyway.

Changes in Ceres’s white spots

3:56 pm

The uncertainty of science: Ground-based observations of Ceres now suggest that the white spots imaged by Dawn undergo subtle unexpected variations

As Ceres rotates every 9 hours, HARPS is so sensitive that it can detect the very slight Doppler shift in spectrum frequency as the bright spots rotate toward and away Earth, but during observations for 2 nights in July and August 2015, more changes not related to Ceres’ spin were detected. “The result was a surprise,” said co-author Antonino Lanza, also from the INAF–Catania Astrophysical Observatory. “We did find the expected changes to the spectrum from the rotation of Ceres, but with considerable other variations from night to night.”

And it appears that these changes are consistent with some kind of volatile (ice) being exposed to sunlight and venting vapor into space, causing an increase in reflectivity. It seems that when Occator experiences solar heating, plumes are produced and then evaporate, creating a complex spectroscopic signal that evolves during that hemisphere’s daytime. This finding appears to be consistent with earlier observations made by Dawn showing a mysterious haze over Occator.

The problem with this theory is that it assumes the white spots are comprised of water ice. However, data from Dawn has instead suggested that the white spots are not water but salt deposits.

It could be that the white spots are salt left behind when water vented from inside Ceres evaporates away, but so far the data from Dawn has not found any evidence of water at the spots. If it was venting there, Dawn should have seen it.

Tea party Republican wins primary for John Boehner’s seat

12:02 pm

A conservative tea party Republican has won the primary for former House Speaker John Boehner’s congressional seat.

If anything should tell the Republican leadership that they aren’t doing what the voters want, even more than the presidential campaign, it is this story. Boehner did nothing but show contempt for the tea party Freedom Caucus in the House, doing anything he could to block them. In the end, they were instrumental in getting him ousted. And as the article notes,

Davidson’s win Tuesday could give those [tea party] lawmakers reason to dig their heels in as things escalate. They can make their case to Republican leaders that, sure, putting their foot down on a proposed budget that increases spending might hinder Republicans’ goal of passing a budget on time. But what they’re doing is really in the interest of a growing number of Republican voters. Look no further than this highly symbolic seat they just won.

Even though I have serious doubts about Donald Trump’s conservatism, his rise is just another indication that the voters are pissed off at the leadership in Congress, from both parties. That leadership had better change its stripes soon, or it will find others taking their place, as has happened with John Boehner..

Starting a fire in space, on purpose

11:47 am

Engineers plan to intentionally start fires in every Cygnus capsule heading for ISS this year, beginning with the next on Tuesday, but they will wait each time until the freighter has been docked, unloaded, and has left the station.

“The specific goals of the SAFFIRE experiments are to investigate the spread of a large-scale fire in microgravity, essentially trying to answer the questions of how large does a fire get and how rapidly does it spread, or how long does it take to get to the point of being really hazardous to the crew.”

NASA intends to run SAFFIRE experiments on three consecutive Cygnus spacecraft launching through the end of this year. The SAFFIRE 1 and 3 tests will use single samples 15.7 inches wide by 37 inches tall to watch the development and spread of a large-scale low-gravity fire. Scientists want to know if there is a limiting flame size and to quantify the size and growth rate of flames over large surfaces. “SAFFIRE is a box with a wind tunnel in it, a flow duct, that contains the sample that will be burned,” said Ruff. With two cameras poised to capture the fire, a hot wire along the upstream edge of the fiberglass-cotton fabric sample will trigger the burn that should last at least 15 or 20 minutes.

This is very clever, using the capsule as a fire test facility when it is on its way back to Earth to burn up in the atmosphere.

High Diving Giraffes

6:01 pm

An evening pause: Based on some emails I have received, I think some people have been fooled by this cool animation and actually think these are real giraffes! This just tells us that it will not be long now before real actors are no longer necessary and it will be possible to do live action films entirely with animation.

Hat tip George Petricko.

Conservatives to block gigantic budget plan

10:54 am

Good news: The conservative Freedom Caucus in the House is moving to block the new 10-year budget plan put forth by the Republican leadership.

And why you ask? The highlighted sentence below explains it all:

The fiscal blueprint, released Tuesday by Budget Committee Chairman Tom Price, R-Ga., relies on eliminating health care subsidies and other coverage provided by Obama’s health care law, sharp cuts to Medicaid, and reprises a plan devised by Ryan years ago that would transform Medicare into a voucher-like program for future retirees.


But as in past years, GOP leaders have no plans to implement the severe cuts recommended by nonbinding blueprint. [emphasis mine]

This budget plan is merely a tool to make us think they are cutting things, when they really have no intention of doing so. When they finally get down to writing the real budget the increases will be there, as will funding for Obamacare and many of Obama’s pet projects, as they have been in all the previous years since the Republicans took power in Congress.

IRS given power to revoke passports

9:53 am

What could possibly go wrong? A new federal law, passed by a Republican Congress, gives the IRS the right to revoke your passport, even as another federal law will soon require many to use that passport for any airline travel, even within the United States.

What should happen is that both these laws should be repealed, now. Otherwise, I fully expect in the coming years that this new IRS power will be used to squelch opposition to those in power, just as the Obama administration used the IRS prior to the 2012 election to block conservatives from fighting his re-election.

Another glorious Democratic leader speaks!

9:47 am

Dumb and dumber: In yesterdays Democratic townhall event, Democratic presidential candidate Hillary Clinton not only claimed that “we didn’t lose a single person” in the regime change in Libya, she seemed unaware that

ISIS is taking up blocs of territory in Libya now, too. So have al-Qaeda affiliates like Ansar al-Sharia — the group that sacked our Benghazi consulate nearly four years ago, thanks in large part to security decisions made by State under Hillary’s leadership. We didn’t give Libya a chance — we destroyed Libya, and left nothing but a viper pit of terror networks to replace it. And Hillary thinks this is a success story.

Be sure to watch the video of Clinton at the link, where she argues that the elections in Libya have worked, installing a moderate government. I guess it was that moderate government that killed our ambassador and three others in Benghazi four years ago.
