Timelapse photography of Fort Jefferson in Dry Tortugas National Park

6:01 pm

An evening pause: From the youtube webpage: “On a remote island hours away from Key West lies the largest masonry structure in the Americas: Fort Jefferson. Built with 16 million bricks, but never finished, the fort served as a prison during Civil War. In 1935, President Franklin D. Roosevelt, upon visiting the island, named it a National Monument, and in 1992 it became part of Dry Tortugas National Park.”

GAO finds issues in management of DOE space nuclear fuel program

5:24 pm

A new Government Accountability Office (GAO) report has found that though the Department of Energy has made good progress in re-establishing a domestic capability for providing NASA with Plutonium-238 as a nuclear power source for its deep space missions, the management of the program has continuing problems.

The report’s [pdf] introduction described the issues so vaguely I was left somewhat baffled. Here’s just part of it:

Moreover, while DOE has adopted a new approach for managing the Supply Project and RPS production—based on a constant production approach—the agency has not developed an implementation plan that identifies milestones and interim steps that can be used to demonstrate progress in meeting production goals and addressing previously identified challenges. GAO’s prior work shows that plans that include milestones and interim steps help an agency to set priorities, use resources efficiently, and monitor progress in achieving agency goals. By developing a plan with milestones and interim steps for DOE’s approach to managing Pu-238 and RPS production, DOE can show progress in implementing its approach and make adjustments when necessary. Lastly, DOE’s new approach to managing the Supply Project does not improve its ability to assess the potential long-term effects of challenges DOE identified, such as chemical processing and reactor availability, or to communicate these effects to NASA.

It sounds like DOE has taken a very lax approach to getting this done, and the GAO is noting this, but doing so in as gentle a way as possible.

Mars Odyssey makes its first observations of Phobos

2:37 pm

Sixteen years after entering Mars orbit Mars Odyssey finally made its first observations of the Martian moon Phobos last week.

Since Odyssey began orbiting the Red Planet in 2001, THEMIS has provided compositional and thermal-properties information from all over Mars, but never before imaged either Martian moon. The Sept. 29 observation was completed to validate that the spacecraft could safely do so, as the start of a possible series of observations of Phobos and Deimos in coming months.

In normal operating mode, Odyssey keeps the THEMIS camera pointed straight down as the spacecraft orbits Mars. In 2014, the spacecraft team at Lockheed Martin Space Systems, Denver; and NASA’s Jet Propulsion Laboratory, Pasadena, California; and the THEMIS team at Arizona State University, Tempe, developed procedures to rotate the spacecraft for upward-looking imaging of a comet passing near Mars. The teams have adapted those procedures for imaging the Martian moons.

The data from this particular observation is less significant than the fact that the spacecraft can now do it. Expect some new results about the Martian moons in the coming months.

Fannie Mae’s new headquarters included $250K chandelier

9:39 am

Government in action! In building its new gold-plated Washington headquarters, officials at Fannie Mae made sure they had the best, spending about $32 million in questionable expenses, including a chandelier that cost $250,000, according to an inspector general report.

The inspector general for the Federal Housing Finance Agency (FHFA), which acts as a conservator for the mortgage lender, recently noted $32 million in questionable costs in an audit for Fannie Mae’s new headquarters in downtown Washington, D.C. Fannie Mae will be the flagship of Midtown Center, which is scheduled to complete construction in June 2018. The inspector general reported that costs for the new headquarters have “risen dramatically,” to $171 million, up from $115 million when the consolidated headquarters was announced in 2015.

The inspector general blamed expensive upgrades for cost overruns, such as a third glass walkway costing $2 million to connect Fannie Mae buildings, $1.2 million for “decorative wood slatted ceilings,” decorative wood “lunch huts,” and pergolas, or garden-style pavilions, in elevator lobbies. FHFA officials have had poor oversight of the project, according to the inspector general, because they “did not review whether any of the major upgrades were cost-effective or whether lower cost alternatives were available.”

Among the upgrades: a $250,000 chandelier that no one was quite sure what it was for.

Read the whole article. It outlines some disgusting corruption in Washington that is unfortunately now the norm.

The Las Vegas shooting, based on police radio communications

9:16 am

This detailed analysis of the police radio traffic during the Las Vegas shooting dispels many of the absurd rumors about what happened, based on actual data.

I spent some time today listening to the audio feed of the police radio traffic for about 90 minutes following the start of the active killer event on Sunday night. If you are interested in active killer response, either from the police or armed citizen perspective, this audio is pure gold. In general, the police had a stellar response. Being able to hear how it played out is an incredible resource for anyone studying the topic.

This article is primarily written for my police readers, but has some very important insights for my armed citizen readers as well.

The post includes the full audio if you wish to hear it yourself. One tidbit that news reports are not covering: “It appears that the shooter had stopped firing by the time the officers isolated him to his room. Most likely, patrol officers would have forced entry into the room if the killer had been firing on their arrival.” This is only about eleven minutes after the first 911 call.

More strange behavior from Tabby’s Star

8:56 am

Astronomers reviewing past data of KIC 8462852, known as Tabby’s Star to the public, have discovered that not only has it been dimming in a variety of inexplicable ways, it also has brightened twice in a manner that eliminates all past theories for its behavior, including alien megastructures.

The latest findings from Carnegie’s Josh Simon and Benjamin Shappee and collaborators take a longer look at the star, going back to 2006—before its strange behavior was detected by Kepler. Astronomers had thought that the star was only getting fainter with time, but the new study shows that it also brightened significantly in 2007 and 2014. These unexpected episodes complicate or rule out nearly all the proposed ideas to explain the star’s observed strangeness.

Up until now, all the changes to the star had involved dimming, though in ways that did not fit any present theory of stellar evolution. Thus, astronomers theorized that the dimming was caused by something moving in front of the star, from comets to dust to alien structures. This new data of two significant brightening events makes all those theories invalid.

Update: More news about Tabby’s Star: Using two space telescopes as well as amateur telescopes on the ground scientists have determined that the dimming must come from an uneven dust cloud.

Viewing options for first National Space Council meeting

12:07 am

Keith Cowing of NASAWatch has located details about the time and video viewing opportunities for Thursday’s first public meeting of the National Space Council.

The event will be streamed online on NASA TV and via Whiteouse.gov starting around 10:00 am. The event itself is only 2 to 2.5 hours long (not mentioned on the advisory).

…There is nothing online anywhere to suggest that the public can attend this event so it looks like it is going to be an expensive photo op with only a select few actually in attendance listening to pre-written statements being read before the cameras. The expense of taking over a large portion of a busy museum seems to be for the purpose of providing impressive backdrops for a meeting that is mostly show and little substance.

The advisory still provides no details about speakers.

First Flight

9:21 pm

The last part in Doug Messier’s series on the commercial aviation/space history, First Flight, is now available.

Messier brings his history of Virgin Galactic up to the present, and then compares their efforts to build a reusable suborbital spacecraft with that of Blue Origin and its New Shepard design. For Virgin Galactic, the comparison does not reflect well upon them. While fourteen years have passed since the company began its so far unsuccessful effort to reach suborbital space, Blue Origin has already done it multiple times, with a reusable ship. And it took Blue Origin about half the time to make that happen.

Rory Feek – Fifty Thousand Names

6:01 pm

An evening pause: The song is by George Jones. It speaks of those who died and are remembered at the Vietnam Veterans Memorial in Washington. Even though that particular war was somewhat misguided, the courage and bravery of those who fought it, and the fact that in the end it did serve to halt for a time the spread of communism and tyranny, should not be forgotten.

There’s stars of David and rosary beads
and crucifixion figurines
and flowers of all colors large and small
There’s a Boy Scout badge and a merit pin
Little American flags waving in the wind
and there’s 50,000 names carved in the wall.

Sadly, there are a lot of very wealthy athletes today who have forgotten this.

Sierra Nevada and Canada sign agreement for using Dream Chaser

3:11 pm

Capitalism in space: Sierra Nevada has signed an agreement with the Canadian Space Agency (CSA) to study ways in which Canada might utilize the company’s reusable Dream Chaser spacecraft.

This agreement is very preliminary, with no apparent specific plans announced nor any exchange of money. It is however another signal of the strong interest that foreign governments have in buying time on Dream Chaser, once it is operational.

Pioneer

12:11 pm

Pioneer

I am today announcing the publication of Pioneer, a science fiction book I first wrote back in 1982 that has languished in my files now for more than three decades. As I note in the introduction,

It was never published because at the time I could not find an agent to market it to book publishers, and was then too naive and shy to attempt to do such things myself.

In viewing several recent science fiction movies, however, I was motivated to pull the final draft of Pioneer from my files, wondering if it might be marketable. I hadn’t read it in decades, and had literally forgotten the story. I started reading expecting a typical first novel, somewhat incoherent and emotionally immature.

Instead I was quite surprised and enthralled. I couldn’t put the book down. Moreover, I was astonished at the coherence of the story and characters. “This is a good book!” I exclaimed to my wife Diane. Nor am I bragging when I say this, since the person who wrote it is someone from many decades ago and who essentially no longer exists.

Thus, I decided it was time to get Pioneer published, especially since this is now a very easy thing to do, no longer requiring either an agent or a book publisher.

The press release announcing the book’s publication provides the story’s premise:
