Fire during Firefly rocket engine test forces evacuations

9:32 am

A fire during an engine test of Firefly Aerospace’s Alpha rocket yesterday has forced local officials to evacuate nearby residents for a short time.

Earlier Wednesday, Firefly Aerospace tweeted an image of a first stage for the company’s Alpha rocket on a vertical test stand at the Briggs facility. In the tweet, Firefly wrote that teams were loading liquid oxygen into a test version of the company’s Alpha booster in preparation for the first hotfire qualification test of the rocket’s first stage.

Firefly later deleted the tweet after local authorities responded to reports of an “explosion” at the test facility in Central Texas, and ordered the closure of roads in the area and the evacuation of nearby residents.

Officials later clarified that no explosion occurred. Tom Markusic, Firefly’s CEO, told KXAN — the NBC television affiliate in Austin — that a fuel leak resulted in a small fire on the test stand. [emphasis mine]

This is not good for the company’s planned launch schedule, which presently calls for the first operational flight in 2020.

At the same time, the company announced the signing of a contract today with a company that will act as a coordinator scheduling multiple smallsat customers on the rocket.

Boeing abruptly exits DARPA’s experimental spaceplane project

5:37 pm

Boeing today announced it is pulling out of DARPA’s Experimental Spaceplane Program, cancelling development of its Phantom Express-1 hyposonic plane.

The Pentagon’s Defense Advanced Research Projects Agency says Boeing is dropping out of its Experimental Spaceplane Program immediately, grounding the XS-1 Phantom Express, even though technical tests had shown the hypersonic space plane concept was feasible. “The detailed engineering activities conducted under the Experimental Spaceplane Program affirmed that no technical showstoppers stand in the way of achieving DARPA’s objectives, and that a system such as XSP would bolster national security,” DARPA said in a statement issued today.

Boeing has provided no clear explanation for this exit. I suspect it might have to do with their other problems related to the 737-Max airplane and the costs it is imposing on the company. Also, the program called for the first test flights in 2020, and it might also be that Boeing had doubts about meeting that goal.

Right now I wonder if Boeing will have to return any of the cash DARPA provided it for the work done so far, out of the total $146 million award. Moreover, at least two other companies had bid for this contract, Masten and Northrop Grumman. Will Boeing’s exit now allow them to pick up the pieces? Or has Boeing’s contract win and sudden exit mainly achieved the goal of stymieing their compeition?

Overall, this decision by Boeing is just another black mark on the company, just one of many that has occurred in the past few years.

UPDATE: It appears that Doug Messier at Parabolic Arc suspects the same Machiavellian maneuvers from Boeing as I.

A couple of years ago, a friend made the surprising predication that DARPA’s Experimental Spaceplane Program (XSP) — a R&D effort designed to produce a rocket capable of being launched 10 times in 10 days — would never see any hardware built.

The reasoning went like this: the winning bidder, Boeing, really wasn’t interested in the technology. The company was actually interested in government funding and keeping other companies from developing the system.

Messier isn’t sure either, noting that the pull out might also have occurred due to the arrival of Boeing’s new CEO, only a week earlier.

Japan to establish its own military space unit

11:32 am

Working in conjunction with the new U.S. Space Force, Japan now plans to establish its own defense-oriented space unit.

The space unit will be added to an existing air base at Fuchu in the western suburbs of Tokyo, where about 20 people will be staffed ahead of a full launch in 2022. The role of the space unit is to conduct satellite-based navigation and communications for other troops in the field, rather than being on the ground.

Abe’s Cabinet in December approved 50.6 billion yen (U.S. $459.2 million) budget in space-related projects, pending parliamentary approval. [emphasis mine]

The highlighted words indicate the unit’s purpose, to provide support from space for the operations of Japan’s allies. This makes sense, as Japan itself has no real army.

Taking back the arts to make them meaningful again

10:31 am

Link here. The essay first outlines the destructive corrupt and meaningless consequences of postmodernism on the arts:

The systematic undermining of the arts were a prerequisite for the Marxist goal of cultural disintegration. Before elitists began decreeing blatantly absurd claims such as mere words can magically transform men into women, or that Jeffrey Epstein killed himself, our cultural institutions replaced art with artifice. What they call “art” is an empty mimicry, lacking substance and significance.

The result has been absurd museum exhibits where garbage, literally garbage, is lauded as great works of art

The essay then describes a new and booming movement in the artistic community, dubbed remodernism, focused on restoring art to its more laudable place in the human heart.

In 2000, two English painters, Charles Thomson and Billy Childish, codified what they called Remodernism, an insurgency against the manipulative and destructive Postmodern status quo. Remodernism acknowledges the purpose of art: an inclusive means of spiritual communion and connection. This inspiring message is particularly in sync with the values of the United States.

Remodernism is the latest iteration of the American character: ordinary people working as explorers and inventors, optimistic, self-reliant and productive. A Remodernist artist formulates expressions of personal liberty to convey higher meaning, personal growth, and connectivity.

Remodernism sees art as a conduit for shareable moments of beauty, enjoyment, comprehension, and truth. Assembling these elements together approaches a state of grace, the ultimate expression of the love bestowed on us by our Creator. We are called to follow His example.

In other words, the goal of art should to be raise us up, rather than tear us down. I couldn’t agree more.

As they say, read it all.

Trunk from Dragon recovered intact

10:03 am

Capitalism in space: In recovering various pieces, including the capsule, dropped in the Atlantic during its January 19 launch abort test, SpaceX (and Elon Musk) were surprised to retrieve the capsule’s trunk section, normally attached below the capsule, largely intact and undamaged.

The recovery does not mean SpaceX will recapture and reuse this component in the future, since on an orbital flight the trunk would go into orbit. What it does suggest strongly is that SpaceX’s engineering is remarkably robust. To quote the old Timex commercial, “Takes a licking, keeps on ticking!” Kudos to them.

An update on the new virus outbreak originating from China

9:51 pm

Link here. The numbers of people so far infected is hardly gigantic, less than 450 worldwide, with almost all confined to one province in China.

You can also find out some general information about this particular virus as well as other related viruses, such as SARS and MERS, in this separate article. All are far less threatening that press reports make them appear. For example, SARS only infected 8,000 people total, killing a little less than 10% of those infected.

This new virus appears so far to be even less deadly, with nine deaths total, about 5%.

While under no condition should this outbreak be ignored or poo-pooed, it is very important to recognize that, at least so far, it is hardly an epidemic that will wipe out civilization. This could change with time, but I doubt it.

Animal life thriving in Fukushima radioactive zone

9:27 pm

The uncertainty of science: Despite fears that the radioactivity released from the Fukushima nuclear accident would make life difficult if not impossible within the 80-mile radius exclusion zone surrounding the reactor, animals are thriving there, in large unexpected numbers.

Now, nearly a decade after the nuclear accident, the wildlife populations appear to be thriving. Animals are most abundant in areas still devoid of humans, with more than 20 species captured in the UGA’s camera study.

Particular species that often find themselves in conflict with humans, especially Fukushima’s wild boar, were most often photographed in human-evacuated areas. Without the threat of humankind, wildlife is flourishing. In the years since the nuclear accident, Japan’s wild boar seems to have taken over abandoned farmland — even moving into abandoned homes. The government hired boar hunters to cull the population prior to re-opening parts of the original exclusion zone in 2017.

This phenomenon has happened before. Life inside the Chernobyl exclusion zone in Ukraine became an accidental wildlife preserve after humans left following the nuclear disaster there in April 1986. [emphasis mine]

This story, and that of Chernobyl, does not prove that radioactivity is harmless. Not at all. What it shows is that we know diddly-squat about its effects on life. For example, one study has shown changes in the weight and size of one species of monkey at Fukushima has shrunk, but have flourished nonetheless.

The oldest known meteorite strike?

9:09 pm

The uncertainty of science: Scientists think they have identified the oldest meteorite strike known on Earth, dated at 2.33 billion years ago, located in a known impact site in Yarrabubba, Western Australia.

Lead author Dr Timmons Erickson, from Curtin’s School of Earth and Planetary Sciences and NASA’s Johnson Space Center, together with a team including Professor Chris Kirkland, Associate Professor Nicholas Timms and Senior Research Fellow Dr Aaron Cavosie, all from Curtin’s School of Earth and Planetary Sciences, analysed the minerals zircon and monazite that were ‘shock recrystallized’ by the asteroid strike, at the base of the eroded crater to determine the exact age of Yarrabubba.

The team inferred that the impact may have occurred into an ice-covered landscape, vaporised a large volume of ice into the atmosphere, and produced a 70km diameter crater in the rocks beneath.

Professor Kirkland said the timing raised the possibility that the Earth’s oldest asteroid impact may have helped lift the planet out of a deep freeze. “Yarrabubba, which sits between Sandstone and Meekatharra in central WA, had been recognised as an impact structure for many years, but its age wasn’t well determined,” Professor Kirkland said. “Now we know the Yarrabubba crater was made right at the end of what’s commonly referred to as the early Snowball Earth – a time when the atmosphere and oceans were evolving and becoming more oxygenated and when rocks deposited on many continents recorded glacial conditions”.

Associate Professor Nicholas Timms noted the precise coincidence between the Yarrabubba impact and the disappearance of glacial deposits. “The age of the Yarrabubba impact matches the demise of a series of ancient glaciations. After the impact, glacial deposits are absent in the rock record for 400 million years. This twist of fate suggests that the large meteorite impact may have influenced global climate,” Associate Professor Timms said. [emphasis mine]

I truly believe they have determined the approximate age of this impact, making it one of the oldest known impacts. Implying however a “precise” linkage to other only vaguely known climate events, and inferring that the former was the cause of the latter seems to me to be a very large overstatement. Their data might suggest this conclusion, but the uncertainties here demand a bit less certitude..
