Scientists have produced a small amount of a self-healing solid composite that not only remembers its shape but can, under certain conditions, heal itself should it break or crack.
Don’t get out your checkbook yet. This is only the preliminary research, though the concepts look very promising.
The competition heats up: The Air Force has awarded Orbital ATK and SpaceX contracts to develop new rocket engines to help end the U.S.’s reliance on Russian rocket engines.
The Orbital contract is initially worth $47 million, with the company committed to spend $31 million of its own money., according to the Defense Department’s daily digest of major contract awards. Eventually the government could pay the company $180 million. SpaceX’s contract meanwhile was for $33.6 million initially for the development of its new Raptor upper stage engine, with a total government payment to be $61 million.
And that’s not all. Later today NASA will announce the winners in its second ISS cargo contract. The competitors are SpaceX, Orbital ATK, and Sierra Nevada. I am hoping the latter two win, since that would allow the construction of a fourth American spacecraft, Sierra Nevada’s Dream Chaser, capable of lifting cargo and crew into space.
An evening pause: This short video demonstrates that all is possible if one combines flying drone capability with that of a road vehicle. I’m not sure if this has any practical value, but it sure is cool to see 1960s comic book engineering come to life.

SpaceX has produced a short video that recaps its last launch and the successful landing of its first stage. I have embedded it below, because it is worth seeing again as the company is preparing to do it again this weekend. It is also worth watching again to see the joyous celebration of everyone watching at the moment, all of whom know deep down that they have just witnessed a significant event in the history of the human race.
An evening pause: Hat tip Kyle Kooy. I don’t think the Chinese military realized that they were marching to this music, but gosh darn it, they sure appear to. As Kyle noted to me, “Somebody took a Chinese military parade and set the music to the American song “Get Lucky” by Daft Punk. … [It] creates a very mesmerizing video that is both upbeat and somewhat eerie at the same time.”
A former employee of Virgin Galactic, in a arbitration dispute, has accused the company of lying about its spacecraft’s safety and performance.
Virgin Galactic’s former vice president of propulsion, Thomas Markusic, has accused Richard Branson’s space company of lying about the safety and performance of its SpaceShipTwo suborbital tourism vehicle. “Dr. Markusic was forced to separate from VG [Virgin Galactic] because the company was defrauding the public about the ability of the vehicles to reach space and was utilizing rocket engine technologies that have a high probability of causing catastrophic failure and loss of life,” according to the document. “VG directed Dr. Markusic to lie to customers about the performance and safety of the company’s hybrid rocket technology,” the document continues. “VG asserts that Dr. Markusic secretly plotted to start his own rocket company and exploited his position at VG; whereas, in reality, Dr. Markusic’s conscience forced him to to leave.”
Read the whole thing. It appears Markusic left Virgin Galactic to form his own company, and in doing so might have violated an anti-competition clause in his contract, resulting in the arbitration dispute. At the same time, his accusations ring true, considering these rumors had been flying about at the time and have since been more or less confirmed.
The competition heats up: In its routine preparations for its January 17th launch, SpaceX has successfully conducted a static fire launch test of the Falcon 9.
The test was longer than usual, 7 seconds, because of the time that has elapsed since the first stage’s last test firing, a delay caused by the launch failure earlier this year.
An evening pause: What could be better? Glowworms, a cave, and beautiful music by Dexter Britain called Light Bridges.

Link here. The skyscraper is over 2,000 feet high and has 128 floors.
The competition heats up: The Russian government has apparently given the go-ahead to the development of a Falcon 9-like modular rocket, original dubbed Soyuz 5 but now called Fenix (Phoenix).
The images at the link show it to be similar in concept to Falcon 9, with its first stage used as a component to produce multiple configurations. With one first stage it would resemble Falcon 9. In its Falcon Heavy configuration it would use three first stages strapped together. Moreover, the article notes that development would begin as expendable, but shift towards re-usability during operation, like Falcon 9. And it does appear that reducing cost is its main driver, since it will involve the development of only one engine and the reuse of it in every stage, like Falcon 9,
If all goes as outlined in the plan (don’t bet on it), the rocket would be operational by 2025, which is the one difference with Falcon 9. SpaceX got its rocket designed and launched in about five years. The Russian governmental system is going to take ten years to do the same..
The article is a detailed explanation of the rocket mentioned by Deputy Prime Minister Dmitri Rogozin during his confusing television briefing on December 30. The irony here is that, while this rocket might be able to compete with the Falcon 9 of 2016, when it becomes operational in 2025 who knows what will be considered competitive.

The competition cools down? Bigelow Aerospace has laid off somewhere between 30 and 50 employees out of approximately 150 total employees.
In a Jan. 6 statement provided to SpaceNews, Bigelow Aerospace President Robert Bigelow said that the company determined that many areas of the company were “overstaffed” and decided to lay off employees to reduce the company’s expenses. “In December of 2015, we analyzed the amount of staff that we employed throughout all of our departments at Bigelow Aerospace, and discovered that numerous departments were overstaffed,” Bigelow said in the statement. “Regrettably, we had to make the choice that, beginning with the New Year, we need to follow standard business protocols, which sensibly requires an attempt to achieve balance in how much staff is necessary.”
The lay-offs do not necessarily indicate the company is failing, only that it is adjusting its payroll to the specific conditions of the moment. They have completed construction of their inflatable module for ISS and now only await its launch. Time to save money until they win their next contract.
