Year: 2015

R.I.P. George Mueller

8:32 am

One of the most important managers during the 1960s and 1970s at NASA, George Mueller (pronounced “Miller”) has passed away at 97 after a short illness.

NASA and sources close to Mueller’s family confirmed his passing on Thursday (Oct. 15).

Mueller, as associate administrator, headed the Office of Manned Space Flight at NASA’s Washington headquarters from 1963 through 1969. During that time, Mueller brought together NASA’s three human spaceflight centers under a common management system, introduced an approach to testing that made landing a man on the moon by the end of the decade possible, played a key part in the design of the United States’ first space station and advocated for a reusable space transportation system that became known as the space shuttle.

Unlike the many government managers that followed him, Mueller’s goal was never to build an empire, but to get humans into space as quickly and as efficiently as possible. If only we had more people like him.

Fractures on Enceladus’s north pole

6:02 pm

Enceladus's North Pole

The Cassini science team has released the first image from Wednesday’s flyby of the Saturn moon Enceladus.

Scientists expected the north polar region of Enceladus to be heavily cratered, based on low-resolution images from the Voyager mission, but the new high-resolution Cassini images show a landscape of stark contrasts. “The northern regions are crisscrossed by a spidery network of gossamer-thin cracks that slice through the craters,” said Paul Helfenstein, a member of the Cassini imaging team at Cornell University, Ithaca, New York. “These thin cracks are ubiquitous on Enceladus, and now we see that they extend across the northern terrains as well.”

To see more you can browse the raw images here.

The next flyby later this month will be especially interesting as they will dip to within 30 miles of the surface.

Ben-Hur – The Chariot Race

6:01 pm

An evening pause: This clip is actually only the last half of the chariot race scene from Ben-Hur (1959), still one of the greatest action sequences ever put on film. And not only was it on film, but they did it without any computer animation. What you see is real, real horses and real chariots and real actors and real very skilled and brave stunt men. (See this short film on how the even earlier 1925 silent-era epic film Ben-Hur version was made, in a similar manner.)

If you get the chance, watch the 1959 film. Truly a great Hollywood epic.

Two more Obamacare state co-ops fail

12:27 pm

Finding out what’s in it: Obamacare co-ops in Tennessee and Kentucky have announced that they are going out of business and their customers need to find new health insurance plans.

The following two paragraphs about the failure of the Kentucky co-op illustrate succinctly what conservatives were saying about Obamacare before it was launched about why it was never going to work:

The co-op lost $50 million last year, partly because over 20,000 more people had purchased the insurance than originally estimated. Glenn Jennings, Kentucky Health Cooperative’s interim CEO, told the Herald-Leader that further financial woes came because many of their new members had not previously had health insurance, leading to “a lot of people with pent up medical needs.” Then, said Jennings, “when they suddenly had health insurance…they began using their benefits.”

Jennings said that they had slowed their losses to $4 million in the first half of 2015, but were counting on substantial federal loans to continue operations. Instead, the feds announced they would only provide 12.6 percent of the funds requested by insurers through the assistance program. Kentucky’s insurers were hoping to get a total of $77 million in loans, but only received $9.7 million.

If insurance companies are forced to take anyone, as Obamacare does, then no one is going to buy insurance until they need it, defeating the entire premise of insurance. Thus, the Kentucky co-op was quickly saddled with too many sick customers and not enough healthy ones to pay the costs. To solve this they were then depending on the government to make up the difference. This however is simply impossible. There just isn’t enough of other people’s tax dollars to fund such inefficiencies.

The unsurprising result: Bankruptcy. As the article notes, of the 23 state co-ops still in operation, 21 are losing money. Expect more bankruptcies to come.

Iran writes its own bill

9:56 am

The bill approved by Iran’s legislature this week is not the deal negotiated by John Kerry and approved by Obama.

Instead, the Majlis approved by a 161 to 59 vote, with 13 abstentions, a nine point document they created which authorizes the Iranian government to move forward on a path that will do at least two things: one, remove international sanctions against Iran, and two, end Israel’s nuclear weapons program.

Got that?

End Israel’s nuclear weapons program. Not end Iran’s nuclear weapons program. Ending Israel’s program is apparently point one of the nine point document approved by the Majlis on Tuesday.

Read it all. Rather than agree to limit their nuclear production, as declared by the idiots in the Obama administration, the legislation allows them to accelerate it. As the article notes, the only person sticking with Obama’s Iran nuclear deal is Obama.

More evidence of giant flash floods on Mars

9:45 am

Mangala Valles

A newly released image from ESA’s Mars Express orbiter shows that catastrophic flooding — caused by ice melted from volcanic activity — created the Mangala Valles channels on Mars.

The perspective image on the right shows the topography of the region, with low points indicated in blue and high points by red. The channel along the right side of the image is Mangala Valles itself, though you can also see additional flood channels to the left of it passing around and through a large crater whose floor now stands above the surrounding terrain caused by the erosion of the rim plus the deposit of sediment inside the crater during the flooding.

I have a soft spot for Mangala Valles. When it was first photographed by the first orbiter missions to Mars in the early 1970s I was struck by its river-like appearance and striking topography. I therefore placed my Martian colony here in one of my efforts at science fiction writing. I figured it a good location for colonization, as there would likely be water and, by roofing over the deep canyon, a colony could be built relatively easily.

Better locations on Mars have since been found, but the location still intrigues me.

Smallsat rocket launchers get NASA contracts

9:21 am

The competition heats up: NASA this week awarded contracts ranging from $4.7 to $6.9 million to three different smallsat launch companies.

The companies are Firefly Space Systems, Rocket Lab USA, and Virgin Galactic. The second is the company that just won the contract to put a privately-built lunar rover on the moon (part of the Google Lunar X-Prize).

In the past, cubesats and other small satellites could only afford to be secondary payloads on much larger rockets. Thus, they were at the mercy of the needs of the primary payload, often resulting in significant unplanned delays before launch. This in turn acted to discourage the development of smallsats. Now, with these private launch companies designed to service them exclusively the smallsat industry should start to boom.

Note also the low cost of these contracts. The small size of cubesats and the launchers designed for them means everything about them costs much less. Putting an unmanned probe into space is thus much more affordable.

Antares failure wipes out Aerojet’s 2nd quarter profits

9:07 am

The settlement between Orbital ATK and Aerojet Rocketdyne over the failure of an Aerojet Russian engine that failed during an Antares launch has wiped out Aerojet’s entire second quarter profit.

The Rancho Cordova rocket engine maker reported a $38.1 million quarterly loss Tuesday, largely the result of a spectacular launchpad explosion last October that forced Aerojet to pay a hefty settlement to a key customer and prompted the end of a profitable supply contract. Aerojet, which has embarked on a cost-cutting program, said the third-quarter loss came to 62 cents a share. It compared to a year-ago loss of $9.9 million, or 18 cents a share.

The company’s stock has also been declining, probably linked to its loss of business to Blue Origin.

Kepler finds a star no one can explain

3:56 pm

Observations using Kepler have uncovered a star whose light fluctuations can only be explained in two ways.

First,

If another star had passed through the unusual star’s system, it could have yanked a sea of comets inward. Provided there were enough of them, the comets could have made the dimming pattern. But that would be an extraordinary coincidence, if that happened so recently, only a few millennia before humans developed the tech to loft a telescope into space. That’s a narrow band of time, cosmically speaking.

Second? Maybe the star’s light is being blocked by a swarm of megastructures built by an alien civilization. They intend to look for radio emissions from the star in wavelengths associated with technology to see if this theory has any possibility.

New global maps of Titan

11:23 am

Titan's North Pole

The Cassini science team has released new maps of Titan, including new maps of both poles, assembled from images taken during the 100 flybys that the spacecraft has made of the moon since it arrived in orbit around Saturn.

The scale is rough, just less than a mile at best, and there is no topographic information because the thick atmosphere allows for no strong sunlight or shadows. The images show differences in surface brightness, which does tell us where Titan’s dark methane lakes are.

This is likely the best we will get of Titan for decades, until another spacecraft is sent there.
