Largest diamond found in more than a century
Miners in Botswana have uncovered the largest single diamond discovered since 1905, more than 1,100 carets.
It is also the second largest diamond ever found.
Vine to Wine
An evening pause: Making wine, the modern way. It is interesting how many steps here are still done by hand when they clearly could be automated. I suspect that it doesn’t pay for this winery to upgrade to more sophisticated equipment because their overall output is relatively small and it is more efficient for these steps to still be done by hand.

ULA concedes GPS competition to SpaceX
The competition cools down: ULA has decided against bidding on a military GPS launch contract, leaving the field clear for SpaceX.
ULA, which for the past decade has launched nearly every U.S. national security satellite, said Nov. 16 it did not submit a bid to launch a GPS 3 satellite for the Air Force in 2018 in part because it does not expect to have an Atlas 5 rocket available for the mission. ULA has been pushing for relief from legislation Congress passed roughly a year ago requiring the Air Force to phase out its use of the Russian-made RD-180 engine that powers ULA’s workhorse Atlas 5 rocket.
This decision might be a lobbying effort by ULA to force Congress to give them additional waivers on using the Atlas 5 engine. Or it could be that they realize that they wouldn’t be able to match SpaceX’s price, and decided it was pointless wasting time and money putting together a bid. Either way, the decision suggests that ULA is definitely challenged in its competition with SpaceX, and until it gets a new lower cost rocket that is not dependent on Russian engines, its ability to compete in the launch market will be seriously hampered.
Short circuit on ISS
An electrical failure on ISS has deprived ISS of one of its main circuits.
They have alternative wiring and are using that, so that all equipment is presently functioning. However, a similar failure in 2014 required a spacewalk to fix. Moreover, they don’t have the necessary spare parts on board to fix the problem. They will have to be shipped up, and it is too late to put them on the Cygnus freighter now packed and ready for launch on December 3.
on account of because
An evening pause: From the 1941 Howard Hawks classic, Ball of Fire, about eight professors who hire a burlesque dancer to explain slang to them. Hat tip to Phil Berardelli, author of Phil’s Favorite 500: Loves of a Moviegoing Lifetime, who notes, “Barbara Stanwyck demonstrates the art of seduction, complete with luminously backlit hair, opposite the uncharacteristically prim Gary Cooper.”

Next Blue Origin test flight before end of year
The competition heats up: Blue Origin not only intends to launch another test flight of its suborbital New Shepard rocket/capsule before the end of 2015, they hope to begin commercial unmanned flights by the second quarter of 2016.
Manned flights will follow, though they don’t say when. Based on this schedule, however, it appears that Blue Origin, which had hardly been on anyone’s radar for most of the last decade, is going to beat Virgin Galactic and XCOR in flying their first commercial flight.
Copenhagen Phil – Ravel’s Bolero
An evening pause: You really can’t pick a better classical piece for a flash mob performance than Bolero. It builds bit by bit, allowing the performers to slowly gather as if by accident. I also noticed that they seemed to be really enjoying the casual dress nature of this performance, which occurred at Coperhagen Central Station on May 2, 2011..

Iridium launch delayed to fix problem
In the heat of competition: The first launch of Iridium’s second generation constellation of satellites will be delayed four months in order to fix a just discovered manufacturing problem in the satellites.
Dubai to use jetpacks to fight fires
Buck Rogers lives! In order to better fight fires among its many high skyscrapers, Dubai officials have purchased 20 jetpacks for use by its firefighters.
Martin Jetpacks have been developed with first responder use in mind. They can be flown by a pilot or via remote control, take off and land vertically, operate in confined spaces (such as close to or between buildings or near trees) and carry commercial payloads of up to 120 kg (265 lb). This functionality means the Jetpacks can provide a variety of first response services. For example, they can be used for surveillance or observation (such as to determine the focus of a fire), transporting equipment to where it is required, rescuing individuals or deploying specialist teams.
Though it sounds cool, remotely controlled drones would make more sense for most of these tasks. The jetpacks might be useful for getting crews in and out of difficult high locations, as well as possibly rescuing trapped victims, but to make this practical will require significant training, something that I don’t see as realistic.

SpaceX successfully tests its Dragon capsule abort rocket thrusters
The competition heats up: SpaceX has successfully tested its abort rocket thrusters that will be used to speed a Dragon capsule away from any rocket during a failed launch.
Named SuperDracos, the engines are arranged in four pairs – SpaceX calls them ‘jetpacks’ – integrated around the outside of the Crew Dragon spacecraft. Firing all at once, the eight engines produce 120,000 pounds of thrust – enough power to accelerate a Crew Dragon from zero to 100 mph in 1.2 seconds. In the unlikely event of an emergency, that power means the ability to lift the crew a safe distance off the launch pad or far away from a booster failing on the way to orbit. That capability was demonstrated earlier this year in a pad abort test that confirmed the SuperDraco design in a flight-like condition.
A normal launch of the Crew Dragon atop a Falcon 9 rocket would not offer the SuperDracos anything to do during the mission since their only responsibility is to fire in an emergency to rescue the crew onboard. Eventually, SpaceX plans to use the SuperDracos in the place of a parachute during landing.
Congress revises law governing commercial space
The competition heats up? Congress this week passed a revision to the Commercial Space Act that they claimed will help encourage the growth of the new industry.
According to the Senate press release, the bill does the following:
- Extend the liability waiver for private space launches until 2023
- Extend ISS operations until 2024
- Establishes a legal right for U.S. companies to mine resources in space
- Demands a new more streamlined framework for the government’s regulation of the industry
The last item is probably mostly blather, since a close look at the bill itself [pdf] reveals that most of these demands are merely requirements that the executive branch write a report. The odious rules that will allow the federal government to regulate and restrict the industry all remain. And even though the bill makes a big deal about establishing these regulations in concert with the industry itself, that only means that today’s players can use the government to make it difficult for new players to get started.
The claim that the bill also establishes “a legal right to resources a U.S. citizen may recover in space consistent with current law and international obligations of the United States,” as noted in the Senate press release, is a very big overstatement. The bill’s wording does nothing to get the U.S. out of the UN’s Outer Space Treaty, which forbids any person or nation from claiming ownership of territory in space. All the bill does is express the desire that American citizens should have the right to own what they mine, while at the same time stating that these resources will be “obtained in accordance with applicable law, including the international obligations of the United States.’’ In other words, the Outer Space Treaty still applies, and you can’t own it.
For what it’s worth, the bill also renames the FAA’s space regulatory agency from “The Office of Space Commercialization” to “The Office of Space Commerce.”
All in all, the bill’s most important overall accomplishment is that it strongly emphasizes and encourages the development of a private space industry, and tries to focus the government’s regulatory efforts in that direction. This ain’t perfect, but it could be considered a step in the right direction.
One more thing to note: Senator Ted Cruz (R-Texas) appears to have been a major player in getting this bill written and passed.
Another new American rocket engine tested successfully
The competition heats up: Sierra Nevada has successfully tested a new rocket engine, dubbed Vortex, specifically designed to fulfill a wide range of uses. From the press release:
These tests demonstrate the ability to transition use of different propellant combinations in the same core rocket engine design with slight changes to accommodate a specific combination of fuel and oxidizer, including propane and kerosene fuels with nitrous oxide (laughing gas) and liquid oxygen oxidizers. This latest development offers customers a suite of engines scalable to higher thrust levels and customer-selected fuel combinations from a single core rocket engine design. ORBITEC’s patented vortex rocket engines utilize a unique swirling propellant flow to naturally cool the engine walls, allowing for the development and manufacture of simpler, low-cost, light-weight and more robust rocket engine systems.
What strikes me about this is that, until SpaceX built its Merlin engine in the mid-2000s, it had been decades since the American aerospace industry had developed a new rocket engine. After the development of the shuttle’s main engines in the late 1970s nothing new was created for the rest of the 20th century. Since Merlin, however, we have seen a string of new engines from several different companies, suggesting that the new renaissance I wrote about back in 2005 is on-going and accelerating.
David Arnold – Independence Day
An evening pause: Vienna’s Radio Symphony Orchestra performs an excerpt of David Arnold’s soundtrack to the 1996 film Independence Day during the 2013 Hollywood in Vienna concert.
The film was incredibly silly, but fun nonetheless. The performance here captures some of that silliness, with the lighting and the smoke and the film clips. Also, the score’s use of a drum and flute in a short section near the middle is clearly intended to refer to the American Revolution, since in the movie the human race, led by Americans, conquers the aliens on the 4th of July, Independence Day..

Noteworthy – Amazing Grace
An evening pause: Normally I do not post music videos where the singers are lip-syncing so that they can stage some clever visuals, as is done in this video. However, the singing is so good, and the singers and song is filled with such joy, that it is worth listening and watching regardless. A good way to end the week.
