Year: 2017

The SpaceX light show yesterday

9:12 am

Falcon 9 launch, December 22, 2017

Numerous news articles today have noted that last night’s launch by SpaceX of ten Iridium satellites produced a somewhat unusual light show for Californians. Reader Frank Kelly sent me some images he took, noting,

I was able to catch the booster ascent, stage separation, second stage burn and what looks like the booster spinning with at least one engine firing. The spinning went on for a while so it must have had some fuel left.

I read SpaceX said they would not land this booster so maybe they had some fun with it for us folks in LA. It spun around for a minute like a pinwheel. A great show.

The image above right is one of his images, reduced in resolution to post here. Below that is a cropped section of the full resolution image, showing the “pinwheel” being performed by the first stage. And as other readers of BtB have also noted, the launch crew was clearly performing engine tests and maneuvers with this first stage, all the way down to the ocean.

As is typical of SpaceX, they waste no opportunity to test their equipment and find out what it can do, on the extreme. I suspect these maneuvers were designed to push the first stage’s ability to recover from an out-of-control spin. From the call-outs by engineers during the launch, it appears that this test was a success, as it appears from those call outs that the first stage “landed” properly upright in the ocean.

Let me add that in reviewing some of the youtube videos posted by my readers in the comments below, I also think these first stage maneuvers might be tests in preparation for the first Falcon Heavy launch, which will involve landing three first stages at the same time, two landing very close together at Kennedy. The flight tests yesterday could be an effort to demonstrate how well they can program those first stages for their return.

SpaceX successfully launches 10 Iridium satellites

7:45 pm

Capitalism in space: SpaceX today successfully launched ten 10 Iridium satellites.

This launch for Iridium reused a first stage from a previous Iridium launch. This was the first time Iridium launched with a used first stage. SpaceX did not try to recover the stage, which could be for several reasons, including the possible desire by the customer that they devote their entire effort to getting the satellites in orbit.

This was also SpaceX’s last launch for the year. The launch standings for the year now are thus:

29 United States
19 Russia
18 SpaceX
15 China

Sometime in the first week of 2018 I will post a full table showing this year’s launches plus the launch totals going back to the early 1980s. It reveals a great deal about the history of the launch industry for the past half century, as well as where that launch industry is likely heading in the coming half century.

On the radio

3:11 pm

On Tuesday, December 19, 2017 I spent an hour with Robert Pratt on his Pratt on Texas radio show. Most of the show was devoted not to space and science but to discussing my weekly updates on the fascist culture on too many of today’s American campuses.

Robert has just let me know that this hour-long interview is going to be replayed twice over the next two weeks, on Christmas Day, December 25, 2017, and on New Year’s Day, January 1, 2018, both times from 6 to 7 pm Central time. He also let me know that the best link to listen is here.

So, if you have nothing better to do during these holidays, here is something that might help to fill your time.

Arecibo returns to operation with images of asteroid Phaethon

10:02 am

The Arecibo Observatory in Puerto Rico has resumed science observations after recovering from Hurricane Maria with new radio images of the asteroid Phaethon.

After several months of downtime after Hurricane Maria blew through, the Arecibo Observatory Planetary Radar has returned to normal operation, providing the highest-resolution images to date of near-Earth asteroid 3200 Phaethon during its Dec. 16 flyby of Earth. The radar images, which are subtle at the available resolution, reveal the asteroid is spheroidal in shape and has a large concavity at least several hundred meters in extent near the leading edge, and a conspicuous dark, circular feature near one of the poles. Arecibo’s radar images of Phaethon have resolutions as fine as about 250 feet (75 meters) per pixel.

The images also revealed that Phaethon, which is considered a potentially hazardous near Earth asteroid, is about 3.6 miles across and is about a half mile larger than previously believed.

Russia to launch luxury hotel room module to ISS?

12:11 am

Capitalism in space: Roscosmos is considering a plan to launch a hotel module to ISS where it could house tourists for profit.

According to a detailed proposal seen by Popular Mechanics, the 20-ton, 15.5-meter-long module would provide 92 cubic meters of pressurized space. It would accommodate four sleeping quarters sized around two cubic meters each and two “hygiene and medical” stations of the same volume. Each private room would also have a porthole with a diameter of 228 millimeters (9 inches), while the lounge area of the module would have a giant 426-millimeter (16-inch) window.

The external structure of the tourist module looks like the Science and Power Module, NEM-1, which Russia is currently building for the International Space Station. The second NEM module had originally been on the books in the station’s assembly scenario, but the Russian government funded only one module. It will serve primarily as a science laboratory and a power-supply station for the ISS.

Now, Russia’s prime space station contractor, RKK Energia, came up with a scheme to pay for the second NEM module through a mix of private and state investments. To make profit, the NEM-2 would be customized for paid visitors.

Makes sense to me. Russia doesn’t really have the money right now to fund a big deep space exploration program. Better they aim for profits in space, as that will keep them in the black and provide them the capital they presently lack.

Japan’s Google Lunar X-Prize rover arrives in India for launch

12:07 am

Capitalism in space: The rover being built by the Japanese team competing for the Google Lunar X-Prize has arrived in India for installation on the PSLV rocket that will launch it into space.

The Sorato rover which is flight ready will be mounted on Team Indus lander at its facility in Jakkur. HAKUTO, one of the five teams competing for the Google Lunar XPRIZE, has signed a ride share agreement with Team Indus (India’s first private aerospace startup) for launching the Sorato along with the Indian rover.

Team Indus’s spacecraft, along with the two rovers, will also carry a few payloads and will be launched onboard ISRO’s workhorse, the PSLV-XL. The launch is expected to take place early next year (before March 8, 2018, the date set by Google to the five privately funded teams to launch the landers and the rovers on the Moon surface).

Several important details here. First, though the Japanese team appears to have all the necessary funds to pay for their flight, Team Indus is still searching for investment, and might not have the money to pay for its share of the flight. What will happen in that case is unclear.

Second, the word Hakuto in Japan means “white rabbit.” This name was chosen because Japanese folklore says a rabbit can be seen in the dark areas of the Moon’s face. This makes Japan’s rover the second rabbit to fly to the moon, after China’s Yutu rover, which in English means “jade rabbit” a name also based on Chinese folklore.

Benjamin Shapiro – Theme from Schindler’s List

6:01 pm

An evening pause: Performed live in 1996, when Shapiro was twelve years old. Note that this is that Ben Shapiro, the orthodox Jew and well-known conservative columnist whom leftists ignorantly love to call a Jew-hater and white supremacist. How they come to that conclusion can only be because they are willfully ignorant or so filled with hate and their ideology that they can’t look at reality with any honesty.

I think, during this holiday season, it is wise to also reflect on humanity’s tragic failures, one of the worst of which was the Holocaust during World War II.

Hat tip Jim Mallamace.

This week in fascist academia

2:47 pm

Time for another depressing update on the fascist and childish culture that unfortunately seems to presently dominate the college campuses of modern America. (To read my earlier updates, posted almost weekly since October, go here.)

To begin, below are some stories illustrating the fascist and intolerant nature of many college administrations:

In every case above, we either have the college administrations taking actions to suppress speech they did not like, or college facility announcing to the world that they haven’t the faintest understanding of freedom of speech or its fundamental basis for the establishment of western civilization.

The last story describes a recent Columbia Journalism Review report about how a number of universities have become very hostile to working journalists, and have even taken actions to have journalists arrested. The universities mentioned including the University of Colorado-Boulder, Keene State College, and two New York state colleges, Bronx Community College and Kingsborough Community College.

However, as I have noted in earlier updates, the fascist culture at academia is unfortunately not limited to the administrators and teachers. Many students advocate intolerance as well.

A star that is devouring its planets?

12:55 pm

Astronomers now think that a nearby star that erratically dims inexplicably does so because of clouds of debris left by the destruction of one or more exoplanets.

A team of U.S. astronomers studying the star RZ Piscium has found evidence suggesting its strange, unpredictable dimming episodes may be caused by vast orbiting clouds of gas and dust, the remains of one or more destroyed planets. “Our observations show there are massive blobs of dust and gas that occasionally block the star’s light and are probably spiraling into it,” said Kristina Punzi, a doctoral student at the Rochester Institute of Technology (RIT) in New York and lead author of a paper describing the findings. “Although there could be other explanations, we suggest this material may have been produced by the break-up of massive orbiting bodies near the star.”

Their data also suggest that the star is young.

China’s 2017 year in review

11:09 am

Link here. The review summarizes every significant achievement and failure that occurred in the Chinese space industry in the past year. Unfortunately, it provides no further information of the cause of the launch failure of Long March 5 in July, nor when that rocket, China’s biggest, will resume launches.

The article also summarizes China’s long term plans as released earlier in the year. This quote struck me as most interesting:

The main contractor for the Chinese space programme, the China Aerospace Science and Technology Corporation (CASC), set out a space transportation roadmap in November. These targets include flying the low-cost Long March 8 by 2020, development of a reusable space plane by 2025, and super heavy-lift launch vehicle, referred to as the Long March 9, to make its maiden flight by 2030.

2035 is the target for full reusability for its launch vehicles, while 2040 is marked for developing next-gen launch vehicles capable of multiple interplanetary round-trips, exploiting space resources as well as a nuclear-powered space shuttle.

I don’t know if China will achieve these goals, but I do know that it intends to try, and that this effort guarantees that the 21st century will be the century where what I call the new colonial movement will take flight, with many nations on Earth pushing and succeeding in the establishment of viable bases on other worlds.
